XFX Radeon RX 580 8GB GDDR5 Black
ASRock Radeon RX 6900 XT OC Formula 16GB GDDR6
Grab the XFX RX 580 if you're building a budget 1080p rig for older or esports titles and want something cheap and easy to run, but know that a lot of owners report black screens, driver crashes, and cards dying within a couple years.
Buy the ASRock RX 6900 XT if you want maxed-out 1440p or 4K gaming with ray tracing and don't mind a 1000W PSU requirement plus a card that runs hot under load.
Principais diferenças
- Raw performance gap is massive: 26,652 vs 8,788 PassMark G3D and 23.04 vs 2.61 FP32 TFLOPS. The 6900 XT is roughly 3x faster in real-world gaming and nearly 9x faster in compute workloads.
- VRAM and memory tech: 16GB GDDR6 with 512 GB/s bandwidth on the 6900 XT vs 8GB GDDR5 with 112 GB/s on the RX 580. That's the difference between comfortable 4K textures and struggling at 1080p in newer titles.
- Power draw is a real trade-off: the RX 580 needs only a 500W PSU and pulls 175W, while the 6900 XT wants 1000W and 300W. Your electricity bill and case cooling will notice the difference.
- Reliability sentiment flips the script: the RX 580 has a higher rating (4.5 vs 4.3 stars) but way more complaints about black screens, driver instability, and early deaths. The 6900 XT owners mostly praise build quality, with heat being the main gripe rather than failures.
- Value depends on your resolution: at 1080p the RX 580 still gets a 33 gaming score vs the 6900 XT's 76, but at 4K it's 19 vs 76. If you're on a 1080p monitor and tight budget, the RX 580 does the job. Anything higher and it falls apart.
