Frequently Asked Questions
Is the Arc A770 better than the RTX 3090?
The Arc A770 is the stronger card overall. It scores 28/100 in synthetic benchmarks and 30/100 in gaming versus 47/100 and 49/100 for the RTX 3090. In practical terms, the Arc A770 is a 1080p high card while the RTX 3090 targets 1440p medium / 1080p ultra. The Arc A770 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, Arc A770 or RTX 3090?
The RTX 3090 costs 330% more for about 68% more performance. The Arc A770 at $349 offers noticeably better performance per dollar. Our value scores reflect this: Arc A770 gets 60/100 and RTX 3090 gets 20/100. If you are building on a tighter budget, the Arc A770 at $349 is the smarter buy. If you can stretch to $1499 and want the extra performance, the RTX 3090 justifies its price for demanding workloads.
Can the Arc A770 or RTX 3090 run games at 4K?
Neither card is an ideal 4K GPU. The RTX 3090 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.
Arc A770 vs RTX 3090 for 1440p gaming -- which is better?
At 1440p, the RTX 3090 is more comfortable but you may need to dial settings down in newer AAA games. The Arc A770 will struggle at 1440p ultra in demanding titles. For a consistent 1440p experience, the RTX 3090 is the safer choice.
What CPU should I pair with the Arc A770 or RTX 3090?
To avoid bottlenecking the Arc A770 (gaming score 30/100), pair it with at least a Ryzen 5 7600 or Ryzen 5 9600X. For the RTX 3090 (gaming score 49/100), 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 Arc A770 worth it in 2026?
The Arc A770 remains a solid buy in 2026. With 16GB of GDDR6 and Xe HPG architecture, it handles current games at 1080p high settings without issues. Support for XeSS extends its lifespan further by boosting frame rates in supported titles. At $349 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 A770 now?
If you need a GPU now, the Arc A770 at $349 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 A770's Xe HPG architecture and 16GB VRAM still have plenty of life left.
How much power does the Arc A770 vs RTX 3090 use?
The RTX 3090 draws 350W TDP versus 225W for the Arc A770, a difference of 125W. For the RTX 3090, a quality 850W PSU is recommended. The Arc A770's significantly lower power draw also means less heat output, which matters in smaller cases or warmer climates. The Arc A770 uses a 2x 8-pin connector while the RTX 3090 needs 2x 8-pin.
How many FPS can I expect from the Arc A770 vs RTX 3090?
Exact FPS varies by game and settings, but based on our gaming benchmark scores (Arc A770: 30/100, RTX 3090: 49/100), the RTX 3090 typically delivers 63% more frames than the Arc A770 at the same resolution and settings. In popular titles at 1440p or 1080p, the RTX 3090 with its 35.6 TFLOPS of compute power and 936 GB/s memory bandwidth pushes well above 60 FPS. Enabling DLSS 2.0 upscaling can boost that by another 30-50% with minimal visual quality loss.
