Our verdict

The RX 7800 XT Graphics Card takes the performance lead with a 35% higher overall score, driven by its more shader cores, 16 GB of memory, and 18.7 TFLOPS TFLOPS of compute power. In gaming benchmarks at 1440p, it delivers roughly 31% more frames per second across demanding titles like Alan Wake 2 and Black Myth Wukong.

However, the Arc B580 Graphics Card tells a compelling value story. At $249 versus the RX 7800 XT Graphics Card's $499 price tag, it costs 100% less while delivering performance that's only 35% behind. Its 12 GB of memory is still more than enough for 1440p and even 4K gaming in most titles.

Our recommendation: for the majority of gamers targeting 1440p or even 4K with upscaling enabled, the Arc B580 Graphics Card is the smarter purchase. The RX 7800 XT Graphics Card only makes sense if you need the absolute maximum performance for native 4K ray tracing, professional 3D rendering, or AI workloads where the extra VRAM and compute power provide a tangible advantage.
