Frequently Asked Questions
Is the RTX 5070 better than the Arc A770?
The RTX 5070 is the stronger card overall. It scores 60/100 in synthetic benchmarks and 63/100 in gaming versus 28/100 and 30/100 for the Arc A770. In practical terms, the RTX 5070 is a 1440p high card while the Arc A770 targets 1080p high. The RTX 5070 also has 12GB of GDDR7 on a 192-bit bus, giving it more headroom for high-res textures and future titles.
Which is the better value, RTX 5070 or Arc A770?
The RTX 5070 costs $200 more (57% premium) but delivers roughly 114% better performance, making the upgrade worthwhile if your budget allows it. Our value scores reflect this: RTX 5070 gets 75/100 and Arc A770 gets 60/100. If you are building on a tighter budget, the Arc A770 at $349 is the smarter buy. If you can stretch to $549 and want the extra performance, the RTX 5070 justifies its price for demanding workloads.
Can the RTX 5070 or Arc A770 run games at 4K?
Neither card is an ideal 4K GPU. The RTX 5070 can manage 4K at medium settings in less demanding titles, but both are really designed for 1440p gaming. If 4K is a priority, consider stepping up to a higher-tier card.
RTX 5070 vs Arc A770 for 1440p gaming -- which is better?
Both GPUs can handle 1440p, but the RTX 5070 does it with more headroom. With 30.9 TFLOPS of compute and 12GB VRAM, it consistently pushes higher frame rates at 1440p ultra compared to the Arc A770's 17.2 TFLOPS and 16GB. If you own a high-refresh 1440p monitor (144Hz+), the RTX 5070's extra performance matters. For a standard 60Hz panel, either card will do fine.
What CPU should I pair with the RTX 5070 or Arc A770?
To avoid bottlenecking the RTX 5070 (gaming score 63/100), pair it with at least a Ryzen 5 9600X or Core i5-14600K. For the Arc A770 (gaming score 30/100), 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 5070 worth it in 2026?
The RTX 5070 remains a solid buy in 2026. With 12GB of GDDR7 and Blackwell architecture, it handles current games at 1440p high settings without issues. Support for DLSS 4 extends its lifespan further by boosting frame rates in supported titles. At $549 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 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 RTX 5070 vs Arc A770 use?
The RTX 5070 draws 250W TDP versus 225W for the Arc A770, a difference of 25W. A 650W PSU should handle either card comfortably. The power difference is modest enough that PSU choice should not be a deciding factor between these two. The Arc A770 uses a 2x 8-pin connector while the RTX 5070 needs 1x 16-pin.
How many FPS can I expect from the RTX 5070 vs Arc A770?
Exact FPS varies by game and settings, but based on our gaming benchmark scores (RTX 5070: 63/100, Arc A770: 30/100), the RTX 5070 typically delivers 110% more frames than the Arc A770 at the same resolution and settings. In popular titles at 1440p, the RTX 5070 with its 30.9 TFLOPS of compute power and 672 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.
