Best DMA Cards in 2025: Artix-7 35T vs 75T vs 100T Compared
Best DMA Cards in 2025: Artix-7 35T vs 75T vs 100T Compared
Choosing the right DMA card depends on your intended use case, firmware requirements, and budget. This guide compares the most popular Artix-7 FPGA DMA card variants — the 35T, 75T, and 100T — so you can make an informed decision before purchasing.
What Makes a Good DMA Card?
A professional DMA card should offer:
- Sufficient FPGA logic capacity — enough logic cells to support your required firmware
- PCIe compatibility — works reliably with standard aftermarket motherboards
- Quality manufacturing — precision assembly and individual testing before dispatch
- Firmware support — compatible with professional firmware development platforms
- Reliable supplier — verified reviews, warranty, and post-sale support
Artix-7 35T DMA Card
The Artix-7 35T is the entry-level configuration in the Xilinx 7-series FPGA family. With 33,280 logic cells, it handles standard DMA configurations reliably and is the most cost-effective option for users new to DMA hardware.
35T specifications:
- 33,280 logic cells
- PCIe Gen3 interface
- Compatible with standard DMA firmware configurations
- Best for: Entry-level setups, budget-conscious buyers, standard workloads
Artix-7 75T DMA Card
The Artix-7 75T is the most widely recommended DMA card for professional configurations. With 75,520 logic cells — more than double the 35T — it supports a wider range of firmware configurations and handles more demanding workloads with greater stability.
75T specifications:
- 75,520 logic cells
- PCIe Gen3 interface
- Greater firmware compatibility — supports advanced configurations
- Best for: Professional setups, users who want maximum firmware flexibility
The 75T is the most popular choice in the FTW DMA range and the card we recommend for most users.
Artix-7 100T DMA Card
The Artix-7 100T is the highest-capacity variant in the 7-series family, offering 101,440 logic cells for the most demanding firmware environments. It is the premium option for users who need maximum FPGA capacity and the broadest possible firmware compatibility.
100T specifications:
- 101,440 logic cells
- PCIe Gen3 interface
- Maximum firmware capacity — supports the most complex configurations
- Best for: Advanced users, demanding firmware requirements, long-term investment
35T vs 75T vs 100T: Quick Comparison
| Model | Logic Cells | Best For | Firmware Compatibility |
|---|---|---|---|
| Artix-7 35T | 33,280 | Entry-level setups | Standard |
| Artix-7 75T | 75,520 | Professional setups | Advanced |
| Artix-7 100T | 101,440 | Demanding workloads | Maximum |
Which DMA Card Should You Buy?
For most users, the Artix-7 75T is the best choice. It provides significantly more FPGA capacity than the 35T, supports a wider range of firmware configurations, and is the most commonly supported card across professional firmware development platforms including Project 7.
If you are on a strict budget or just starting out, the 35T is a solid entry point that handles standard configurations reliably. If you need maximum capacity and plan to run advanced firmware long-term, the 100T is worth the investment.
