Frequently Asked Questions
Is the RX 7800 XT better than the Arc B570?
The RX 7800 XT is the stronger card overall. It scores 43/100 in synthetic benchmarks and 46/100 in gaming versus 25/100 and 27/100 for the Arc B570. In practical terms, the RX 7800 XT is a 1440p medium / 1080p ultra card while the Arc B570 targets 1080p high. The RX 7800 XT also has 16GB of GDDR6 on a 256-bit bus, giving it more headroom for high-res textures and future titles.
Which is the better value, RX 7800 XT or Arc B570?
The RX 7800 XT costs 128% more for about 72% more performance. The Arc B570 at $219 offers noticeably better performance per dollar. Our value scores reflect this: RX 7800 XT gets 72/100 and Arc B570 gets 84/100. If you are building on a tighter budget, the Arc B570 at $219 is the smarter buy. If you can stretch to $499 and want the extra performance, the RX 7800 XT justifies its price for demanding workloads.
Can the RX 7800 XT or Arc B570 run games at 4K?
Neither card is an ideal 4K GPU. The RX 7800 XT can manage 4K at medium settings in less demanding titles, but both are really designed for 1440p or 1080p gaming. If 4K is a priority, consider stepping up to a higher-tier card.
RX 7800 XT vs Arc B570 for 1440p gaming -- which is better?
At 1440p, the RX 7800 XT is more comfortable but you may need to dial settings down in newer AAA games. The Arc B570 will struggle at 1440p ultra in demanding titles. For a consistent 1440p experience, the RX 7800 XT is the safer choice.
What CPU should I pair with the RX 7800 XT or Arc B570?
To avoid bottlenecking the RX 7800 XT (gaming score 46/100), pair it with at least a Ryzen 5 7600 or Ryzen 5 9600X. For the Arc B570 (gaming score 27/100), a Ryzen 5 7600 or Ryzen 5 9600X will keep things balanced. Overspending on the CPU relative to the GPU -- or vice versa -- leaves performance on the table. As a rule of thumb, your CPU should cost roughly 40-60% of your GPU budget for a gaming-focused build.
Is the RX 7800 XT worth it in 2026?
The RX 7800 XT remains a solid buy in 2026. With 16GB of GDDR6 and RDNA 3 architecture, it handles current games at 1440p medium / 1080p ultra settings without issues. Support for FSR 3 extends its lifespan further by boosting frame rates in supported titles. At $499 MSRP, it offers strong value and should stay relevant for at least another 2-3 years of AAA gaming.
Should I wait for next-gen or buy the Arc B570 now?
If you need a GPU now, the Arc B570 at $219 is a perfectly capable 1080p card. The latest GPUs (NVIDIA RTX 50-series Blackwell, AMD RDNA 4) are now available, so consider comparing against the newest options in your budget. The Arc B570's Xe2 (Battlemage) architecture and 10GB VRAM still have plenty of life left.
How much power does the RX 7800 XT vs Arc B570 use?
The RX 7800 XT draws 263W TDP versus 150W for the Arc B570, a difference of 113W. A 650W PSU should handle either card comfortably. The Arc B570's significantly lower power draw also means less heat output, which matters in smaller cases or warmer climates. The Arc B570 uses a 1x 8-pin connector while the RX 7800 XT needs 2x 8-pin.
How many FPS can I expect from the RX 7800 XT vs Arc B570?
Exact FPS varies by game and settings, but based on our gaming benchmark scores (RX 7800 XT: 46/100, Arc B570: 27/100), the RX 7800 XT typically delivers 70% more frames than the Arc B570 at the same resolution and settings. In popular titles at 1440p or 1080p, the RX 7800 XT with its 18.7 TFLOPS of compute power and 624 GB/s memory bandwidth pushes well above 60 FPS. Enabling FSR 3 upscaling can boost that by another 30-50% with minimal visual quality loss.
