Frequently Asked Questions
Is the RTX 5080 better than the Arc B570?
The RTX 5080 is the stronger card overall. It scores 77/100 in synthetic benchmarks and 80/100 in gaming versus 25/100 and 27/100 for the Arc B570. In practical terms, the RTX 5080 is a 4K medium-to-high / 1440p ultra card while the Arc B570 targets 1080p high. The RTX 5080 also has 16GB of GDDR7 on a 256-bit bus, giving it more headroom for high-res textures and future titles.
Which is the better value, RTX 5080 or Arc B570?
The RTX 5080 costs 356% more for about 208% more performance. The Arc B570 at $219 offers noticeably better performance per dollar. Our value scores reflect this: RTX 5080 gets 52/100 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 $999 and want the extra performance, the RTX 5080 justifies its price for demanding workloads.
Can the RTX 5080 or Arc B570 run games at 4K?
The RTX 5080 handles 4K gaming well, delivering playable frame rates in most AAA titles at high-to-ultra settings especially with DLSS 4 upscaling enabled. The Arc B570 is better suited to 1440p or 1080p gaming, where 10GB of VRAM is adequate. For a native 4K experience without heavy reliance on upscaling, the RTX 5080 is the clear pick.
RTX 5080 vs Arc B570 for 1440p gaming -- which is better?
Both GPUs can handle 1440p, but the RTX 5080 does it with more headroom. With 56.3 TFLOPS of compute and 16GB VRAM, it consistently pushes higher frame rates at 1440p ultra compared to the Arc B570's 11.5 TFLOPS and 10GB. If you own a high-refresh 1440p monitor (144Hz+), the RTX 5080's extra performance matters. For a standard 60Hz panel, either card will do fine.
What CPU should I pair with the RTX 5080 or Arc B570?
To avoid bottlenecking the RTX 5080 (gaming score 80/100), pair it with at least a Ryzen 7 9800X3D or Core Ultra 7 265K. 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 RTX 5080 worth it in 2026?
The RTX 5080 remains a solid buy in 2026. With 16GB of GDDR7 and Blackwell architecture, it handles current games at 4K medium-to-high / 1440p ultra settings without issues. Support for DLSS 4 extends its lifespan further by boosting frame rates in supported titles. At $999 MSRP, it is on the pricier side, but you are paying for top-tier performance that will age gracefully.
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 RTX 5080 vs Arc B570 use?
The RTX 5080 draws 360W TDP versus 150W for the Arc B570, a difference of 210W. For the RTX 5080, a quality 850W PSU is recommended. 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 RTX 5080 needs 1x 16-pin.
How many FPS can I expect from the RTX 5080 vs Arc B570?
Exact FPS varies by game and settings, but based on our gaming benchmark scores (RTX 5080: 80/100, Arc B570: 27/100), the RTX 5080 typically delivers 196% more frames than the Arc B570 at the same resolution and settings. In popular titles at 4K or 1440p ultrawide, the RTX 5080 with its 56.3 TFLOPS of compute power and 960 GB/s memory bandwidth pushes well above 60 FPS. Enabling DLSS 4 upscaling can boost that by another 30-50% with minimal visual quality loss.
