Key Differences

• The XFX has 16GB of VRAM on a 256-bit bus with 644.6 GB/s of bandwidth, while the 51Risc makes do with 6GB on a 192-bit bus at 288 GB/s. That's a massive gap for modern games and any kind of AI workload.
• Raw compute is not even close: 36.13 FP32 TFLOPS on the XFX vs 5.44 on the 51Risc. PassMark G3D scores tell the same story, 25,398 vs 12,696.
• Power draw flips the script. The XFX pulls 245W and wants an 800W PSU, while the 51Risc sips 125W and runs fine on a 500W unit. Your electricity bill and PSU budget will notice the difference.
• The XFX scores 77 for 4K gaming and 78 for 1440p, while the 51Risc lands at 19 and 28. The 51Risc is really a 1080p card at best, and even there it scores 35 vs the XFX's 80.
• Customer sentiment is strong for the XFX at 4.8/5 with owners praising the cooling and massive performance jumps, but multiple buyers warn it barely fits in their cases. The 51Risc sits at 4.4/5 with solid value-for-money feedback, but some users report power connector issues and early defects.
