RTX A2000 vs RX 6400: Which Should You Actually Buy?
A head-to-head comparison of the RTX A2000 and the RX 6400. NVIDIA 6 GB GDDR6, ~70 W. Last updated 2026-04-22.
RTX A2000 vs RX 6400: the short version
Two strong options in the same gpu class, aimed at different buyers. Below is a clean side-by-side, the real performance gap, and a no-nonsense recommendation so you stop second-guessing and buy the one that fits your build and budget.
Side-by-side specs
| Spec | RTX A2000 | RX 6400 | | --- | --- | --- | | Vendor | NVIDIA | AMD | | Tier | entry | entry | | Released | 2021 | 2022 | | VRAM | 6 GB GDDR6 | 4 GB GDDR6 | | Board power | 70 W | 53 W |
Real-world performance (estimated)
Estimated average FPS from a tuned config — your CPU, resolution and settings shift these, but the gap between the two holds:
| Model | 1080P Low | 1080P Med | 1080P High | 2K Med | 4K Med | | --- | --- | --- | --- | --- | --- | | RTX A2000 | ~67 | ~54 | ~42 | ~30 | ~14 | | RX 6400 | ~65 | ~52 | ~40 | ~29 | ~14 |
Head-to-head: who wins what
- Performance: RTX A2000 and RX 6400 trade blows by workload. RTX A2000 has the edge where its stronger 6 GB GDDR6 and 70 W of headroom matters; RX 6400 wins the rest.
- Efficiency: RX 6400 draws less power and is easier to cool and power.
- Value: Same-class rivals shift price constantly — check current street pricing and let the cheaper one at your target resolution decide value.
- Our pick: Buy RTX A2000 if you want the outright ceiling and can cool/power it. Buy RX 6400 if you want lower power, lower cost, or a feature the other lacks. (Plan for ~70 W board power plus the rest of the system.)
