Achronix FPGA covers two product lines from Achronix Semiconductor: the standalone Speedster7t FPGA family and the Speedcore embedded FPGA (eFPGA) IP that gets built directly into a customer’s own ASIC. Both run on a 7nm process and target data-acceleration workloads — AI inference, 400G networking, high-frequency trading — where a general-purpose Xilinx or Altera part runs out of bandwidth. Here’s what most product pages skip: you won’t find a bare Speedster7t die sitting in a Digi-Key cart with a live stock counter next to it. Achronix sells through regional franchised distributors, direct sales representatives, and card-level partners, and knowing which channel a quote actually came from matters as much as picking the right part number.
- Achronix FPGA = the Speedster7t standalone FPGA family (AC7t700/800/1400/1500) plus Speedcore eFPGA IP, both built on TSMC’s 7nm process
- There’s no public per-unit price for bare Speedster7t die; the VectorPath S7t-VG6 accelerator card lists at an $8,495 MSRP
- Parts move through regional franchised distributors and direct sales reps, not general open-stock catalog inventory
- Genuine parts trace back to an authorized channel by date and lot code; anything that doesn’t needs incoming inspection before it reaches your line
What Is Achronix FPGA? Speedster7t vs. Speedcore Explained
Achronix Semiconductor is a fabless chipmaker headquartered in Santa Clara, California. It was founded in 2004 in Ithaca, New York, on FPGA architecture licensed from Cornell University research, then relocated to Silicon Valley in 2006. It’s a genuinely small player next to AMD (Xilinx) and Intel (Altera), but it holds two firsts worth knowing if you’re specifying high-bandwidth compute: Achronix shipped the industry’s first FPGA built on a 7nm process node, and it was first to build dedicated machine learning processor (MLP) blocks directly into FPGA fabric instead of repurposing generic DSP slices.
That history explains the product split. Speedster7t is the standalone FPGA — a packaged BGA component you place on a board like any other IC. Speedcore is the same underlying logic fabric, delivered instead as licensable eFPGA IP: Achronix hands you a GDSII hard macro sized to your specified LUT, memory, and DSP/MLP resource counts, and you drop it directly into your own ASIC or SoC design. The two families share LUT architecture, MLP blocks, and tool flow on purpose — you can prototype on a Speedster7t FPGA, validate your RTL, then migrate the same design into a Speedcore instance once volume justifies the move to a custom ASIC. Xilinx and Intel don’t offer that migration path; you commit to a standalone FPGA or a fixed-function ASIC from day one.
Both families lean on the same architectural centerpiece: a two-dimensional network-on-chip (2D NoC) that moves data between the FPGA fabric and its high-speed interfaces — GDDR6, 400G Ethernet, PCIe Gen5 — without routing wide buses through general-purpose programmable logic the way a conventional FPGA has to. On the flagship AC7t1500, that NoC carries more than 20 Tbps of cross-sectional bidirectional bandwidth out to over 80 access points across the die.
Achronix’s own pitch is that it’s the only independent supplier shipping both standalone FPGAs and licensable eFPGA IP in volume production at the same time — Xilinx (now AMD) and Intel (Altera) each offer one or the other, not both from a single shared architecture. Whether that distinction matters to your project depends on whether you’re building one board or already planning the ASIC transition three years out.
Achronix FPGA Series Compared: Speedster7t and Speedcore Specs
Achronix’s standalone lineup spans four devices in the Speedster7t family, anchored by the entry-level AC7t800 and the flagship AC7t1500 — the part you’ll see specified in most accelerator cards. AC7t700 and AC7t1400 fill out the range between them. Speedcore eFPGA IP runs alongside as a separate, fully configurable product line built for embedded designs rather than a board-mounted package.
| Device / IP | Logic Capacity | Process Node | GDDR6 Bandwidth | 2D NoC Bandwidth | Networking / PCIe |
| AC7t800 (entry) | ~326K 6-input LUTs | TSMC 7nm FinFET | Fewer GDDR6 channels than AC7t1500 | 12+ Tbps | Up to 400GbE / Gen5 x16 |
| AC7t1400 / AC7t1500 (flagship) | Up to 692K 6-input LUTs (1,522K 4-input equiv.) | TSMC 7nm FinFET | Up to 4 Tbps (8 channels) | 20+ Tbps | Up to 2x400GbE / Gen5 x16 |
| Speedcore eFPGA IP | Configurable: <10K to >1M LUTs | TSMC 7nm / 12FFC / 16FFC | Customer-defined (no fixed I/O) | Optional, scalable NoC | Customer-defined |
A few numbers beyond the table matter for board planning: the AC7t1500’s SerDes transceivers run up to 112 Gbps per lane — fast enough that they’re commonly the limiting factor in layout, not the FPGA fabric itself. Speedcore IP tops out at a 750 MHz max clock, with a typical operating range of 300–500 MHz — meaningfully slower than the 1 GHz-plus an ASIC’s fixed logic runs at, which is exactly why a Speedcore boundary needs deliberate clock-domain-crossing design rather than an afterthought.
Achronix also shipped a newer card in 2025 — the VectorPath 815 (VP815), built around the same AC7t1500 FPGA but aimed specifically at generative AI inference and HPC workloads, including support for lower-precision 1-bit/2-bit/4-bit inference formats. If your application is AI-inference-specific rather than general data acceleration, it’s worth comparing against the original S7t-VG6 before you default to the older card.
How Much Does an Achronix FPGA Cost?
Here’s the honest answer: Achronix doesn’t publish a per-unit price for bare Speedster7t die, and a sourcing page that quotes you one with total confidence is worth questioning. High-end datacenter FPGAs are priced by quote, not by list — the number depends on volume tier, memory and package configuration, and whether you’re buying through a distributor markup or Achronix’s direct channel.
This isn’t unusual for the category. Enterprise-tier FPGAs at this performance level almost never carry public unit pricing the way a $2 microcontroller does — the die is expensive to fabricate on a 7nm process, volumes are a fraction of consumer silicon, and configuration options like memory density, package, and temperature grade change the bill of materials enough that a single sticker price wouldn’t tell you much anyway.
What is public: the VectorPath S7t-VG6 accelerator card — an AC7t1500 pre-mounted on a PCIe card, co-developed with BittWare — launched at $7,500 in 2019 and lists at an $8,495 MSRP following its PCIe Gen5 certification. That’s a reasonable proxy for what a fully populated AC7t1500 platform costs an end user, even though it tells you nothing about what the bare die costs a board house buying in volume for a custom design.
Speedcore eFPGA IP pricing works differently again: you’re licensing a hard macro sized to the logic, memory, and DSP/MLP resources you specify, plus the non-recurring engineering (NRE) to integrate it into your ASIC. That’s real money and real schedule committed up front. At production volume, eliminating a standalone FPGA’s package, unused I/O pins, and board footprint can cut per-unit cost meaningfully — it’s the trade Achronix built Speedcore for. Below a few thousand units a year, though, the NRE rarely amortizes, and a standalone Speedster7t part stays the cheaper path. That’s worth running the numbers on before you commit either way, not after.
One thing worth flagging before you request quotes: a price for an AC7t1400 or AC7t1500 that comes in well under what the VectorPath card’s own component cost would imply is a reason to slow down, not a reason to order — more on why in the sourcing section below.
Achronix Distributor and Sales Channels: How to Source Genuine Parts
Unlike a general-purpose logic IC, Achronix doesn’t move its standalone FPGAs through the same open-stock catalog model you’d expect from Digi-Key or Mouser’s typical inventory. Parts reach customers through three channels:
- Direct sales — Achronix maintains its own regional sales representatives by territory; an independent rep firm handles inquiries across most U.S. states, for example. This is the default route for a new design-in, especially at the AC7t1400/1500 tier.
- Regional franchised distributors — Achronix appoints exclusive, authorized distributors by geography. Nexcomm Asia became the authorized distributor for the ASEAN and India region in 2021; ACAL Technology covers parts of the EU. These are legally authorized channels with warranty and return backing from Achronix itself, not resellers operating on their own terms.
- Card-level catalog availability — you can buy a Speedster7t FPGA today without going through either channel above, just not as a bare chip. BittWare’s VectorPath and related accelerator cards, which carry the AC7t1500, are stocked and sold through Mouser the same way any other catalog part is.
None of these three channels are mutually exclusive on a single project, either. It’s common to prototype against a card-level VectorPath bought through Mouser, then move to a direct- or distributor-sourced bare die once the design locks and volume production starts — which means the sourcing question isn’t a one-time decision made at kickoff, it’s one you revisit at each stage of the program.
That third point tends to surprise people. If your BOM calls out the bare Speedster7t die for a custom board, the part reaching you through a mainstream catalog distributor’s live “in stock” count is the exception, not the rule — most standalone die volume moves through the direct and regional-distributor channels above, quoted rather than shelf-priced. A site that shows a specific unit count in stock for the bare AC7t1500 is telling you something about its own sourcing that’s worth asking about directly.
This is where FPGA.IO’s component sourcing team earns its keep on an Achronix-based build: we verify which of these channels a quoted lot actually came from before it lands on your BOM, not after the boards are populated. For a design that’s going into full PCB assembly with us, that verification runs as part of the same DFM review we apply to every other line item — one submission covers the FPGA and the rest of the bill of materials together.
Avoiding Counterfeit or Mismarked Achronix FPGAs Before Assembly
Achronix parts are expensive, allocation-constrained at the high end, and — like any component with strong demand and price volatility — a target for remarking and relabeling in the secondary market. SAE International’s AS6081 standard (Fraudulent/Counterfeit Electronic Parts: Avoidance, Detection, Mitigation, and Disposition — Distributors, updated to AS6081A in 2023) exists specifically for this problem. It was written for aerospace and defense supply chains, but its practices hold up just as well on a commercial data-center or networking build.
A real example from our own line: a test-and-measurement customer sent us a partial reel of AC7t800-class parts sourced through a marketplace broker ahead of a scheduled build. Incoming AOI flagged inconsistent laser-mark depth across parts sharing the same lot code — a classic resurfacing signature, not a manufacturing defect. We rejected the lot and re-sourced through an Achronix-authorized channel before assembly started. It cost about two weeks against the original schedule, which is considerably cheaper than a field failure on a shipped unit.
Before you release a PO for an Achronix part sourced outside Achronix’s direct or franchised channels:
- Request the seller’s franchise or authorization documentation — a legitimate authorized distributor provides it without hesitation.
- Cross-check the date and lot code format against what Achronix’s own datasheet documents for that device family.
- Run incoming AOI and X-ray inspection on the lot before it reaches the SMT line — on a package this size, a hidden defect isn’t visible after reflow.
- Treat a quote priced well under the VectorPath card’s own implied component cost as a reason to slow down, not speed up.
- Keep the certificate of conformance and chain-of-custody paperwork attached to the physical lot, not filed away in an email thread.
The board side of this matters too. IPC-7095 (Design and Assembly Process Implementation for BGAs) governs how a package this size should be inspected and, if necessary, reworked. It sets single solder-ball voiding around 25% of ball diameter as the threshold for engineering evaluation, and above 50% as generally unacceptable. On a 2,597-ball, 52.5 mm package that’s usually the single most expensive line item on the BOM, that’s not a detail worth skipping.
Achronix FPGA Applications: AI Inference, Networking, and 5G
AI Inference and Machine Learning Acceleration
The distributed MLP blocks, combined with high-bandwidth GDDR6 memory, are built specifically for neural network inference rather than training. Each MLP supports integer formats from 4-bit through 24-bit precision plus bfloat16 and block floating-point, so a design can trade precision against throughput without leaving the fabric. Unlike a GPU, which needs large batch sizes to stay efficient because of its SIMD architecture, an FPGA can run many parallel low-latency pipelines simultaneously — the reason Achronix parts show up in real-time inference and automatic speech recognition deployments where response time matters more than raw batch throughput.
400G Networking and SmartNICs
Speedster7t’s 400G Ethernet MACs and direct 2D NoC connection are built for the kind of terabit-scale switching that conventional FPGA routing can’t sustain. That makes the part a natural fit for SmartNICs and data-path acceleration in environments running SDN, Open vSwitch, or NFV, where packet processing has to keep pace with the link rate rather than fall behind it.
5G/6G Wireless Infrastructure
Distributed unit (DU) and central unit (CU) acceleration for 5G/6G radio access networks leans on the same combination of high SerDes rates and deterministic NoC latency. Because Speedcore eFPGA IP shares the same architecture, semiconductor vendors building custom baseband processors can embed exactly the amount of programmable logic their design needs rather than carrying a full standalone FPGA’s I/O and package overhead.
High-Frequency Trading and Low-Latency Compute
Speedster7t keeps a direct connection between SerDes and fabric rather than routing through an intermediate chiplet interconnect, which matters when every nanosecond of latency in market-data processing and order execution has a dollar value attached to it.
Automotive and Industrial via Speedcore eFPGA
Speedcore eFPGA IP also shows up in automotive and industrial designs, where the driver isn’t raw bandwidth but supply-chain risk. A fixed-function ASIC that goes end-of-life mid-program forces a redesign; embedding reconfigurable logic into that same ASIC gives a design team room to patch a protocol change, add a sensor interface, or work around a second-source silicon issue without a full re-spin. That’s a different argument for eFPGA than the AI or networking case above — it’s about de-risking a ten-year program, not squeezing out extra TOPS.
Designing Your Board Around a Speedster7t FPGA: DFM Checklist
A 2,597-pin FBGA carrying 112 Gbps SerDes lanes doesn’t forgive layout shortcuts the way a QFN microcontroller does. A few areas deserve attention before you send Gerbers anywhere:
- Controlled impedance and differential routing — SerDes traces typically target 85Ω differential, with minimal via stubs; plan for via-in-pad or back-drilling on any transition that would otherwise leave a stub long enough to resonate at your target data rate.
- Power delivery — the AC7t1500 draws from multiple independent rails (core, I/O banks, SerDes domains), and Achronix’s own reference designs lean on partners like Monolithic Power Systems for sequencing; get your PMIC vendor involved during schematic capture, not after layout is done.
- GDDR6 and DDR4/5 symmetry — memory interface routing needs matched trace lengths and consistent reference-plane continuity across all channels, since the PHY is JEDEC-compliant and DFI 4.0-compliant but not forgiving of asymmetric layout.
- Thermal and copper pour discipline — a package moving this much data dissipates real power in a small footprint; don’t treat thermal relief and copper pour as a last-minute layer-stack decision.
- Stack-up and layer count — the pin density on this package typically drives a higher layer count than the rest of your board would otherwise need; size your stack-up around the FPGA’s breakout requirements, not the average net on the board.
Achronix backs all of this with real board-level documentation, not just a datasheet: the Speedster7t AC7t1500 Board Designer’s Guide (UG101) walks through GDDR6 and DDR4 channel topologies, signal-integrity sign-off methodology, and power-rail sequencing in board-level detail. Pull it before you finalize stack-up, not after a first spin comes back with a signal integrity problem you could have caught on paper.
First-pass yield matters more here than on a typical board, for one simple reason: reworking a component this expensive, on a BGA assembly this fine-pitch, is a bigger risk than reworking almost anything else on the bill of materials. That’s the case for running a proper DFM pass — checking pad geometry, via strategy, and stencil design against the package before you commit to a build — rather than finding out during first article inspection. It’s also why BGA assembly on a part like this is worth sourcing from a shop that runs X-ray inspection as a standard step, not an optional add-on.
Frequently Asked Questions About Achronix FPGA Distributors
Is there an official Achronix distributor?
Yes — Achronix appoints regional franchised distributors rather than selling through one global catalog distributor. Nexcomm Asia covers ASEAN and India, ACAL Technology covers parts of the EU, and WPG Americas also carries the line. Which one is current for your region is worth confirming directly, since appointments do change.
Can I buy a single Achronix Speedster7t FPGA for a prototype?
Not easily as a bare die — standalone Speedster7t parts are typically quoted through direct sales or a regional distributor rather than sold as single-unit catalog stock. The practical prototyping path is the VectorPath accelerator card, which carries the AC7t1500 and is available through catalog distributors like Mouser as a complete PCIe board.
What’s the difference between Achronix Speedster7t and Speedcore?
Speedster7t is a standalone, packaged FPGA you mount on a board like any other BGA component. Speedcore is the same logic architecture licensed as eFPGA IP — a GDSII hard macro you embed directly into your own ASIC or SoC. Both share LUT, MLP, and tool-flow compatibility, so designs can migrate from one to the other.
How much does an Achronix VectorPath accelerator card cost?
The VectorPath S7t-VG6, which carries the flagship AC7t1500 FPGA, launched at $7,500 in 2019 and currently lists at an $8,495 MSRP following PCIe Gen5 certification. Bare-die pricing for a custom board isn’t public and depends on volume, configuration, and sales channel.
What is the lead time for Achronix FPGAs?
Lead time varies by device, channel, and current allocation. Achronix has stated it maintains fab capacity and packaging inventory specifically to keep lead times competitive during supply constraints, but the only reliable number is the one your distributor or sales rep confirms at the time you quote — it moves with market conditions.
How can I tell if an Achronix FPGA part is genuine?
Request franchise or authorization documentation from the seller, cross-check the date and lot code format against Achronix’s datasheet, and run incoming AOI and X-ray inspection before the part reaches your SMT line. A price significantly below what an authorized channel would quote is the most common warning sign.
Can FPGA.IO source and assemble boards using Achronix FPGAs?
Yes. Our component sourcing team verifies the channel behind any Achronix part quoted for your BOM, and our BGA assembly line runs AOI and X-ray incoming inspection as standard on high-value, fine-pitch packages like the Speedster7t family before they reach the SMT line.
Does Achronix make a lower-cost or entry-level FPGA?
Within the Speedster7t family, the AC7t800 is the power-efficient, lower-density entry point, built on the same 7nm architecture as the flagship AC7t1500 but with less logic and fewer memory channels. For embedded designs, Speedcore eFPGA IP can also be sized down to under 10,000 LUTs — well below anything a standalone device offers.
Getting Your Achronix FPGA Board From Schematic to Assembly
Specifying an Achronix FPGA is the easy part — the Speedster7t and Speedcore datasheets tell you exactly what the silicon does. Getting a genuine part onto a board that’s been laid out to handle 112 Gbps SerDes and an 8-channel GDDR6 interface, without a sourcing shortcut turning into a field failure eighteen months later, is where most of the actual risk sits. A board built around a single component costing thousands of dollars doesn’t get a second chance at a bad reflow profile or a rejected lot discovered after populated boards are already sitting in a test fixture. That’s worth planning for before you release a PO, not after a lot shows up with a date code that doesn’t quite match the datasheet.
Send us your Gerbers, BOM, and Achronix part numbers, and we’ll fold the sourcing verification into the same PCB assembly quote as the rest of your build.
