Frequently Asked Questions
Is the RTX 4070 better than the Arc A770?
The RTX 4070 is the stronger card overall. It scores 44/100 in synthetic benchmarks and 47/100 in gaming versus 28/100 and 30/100 for the Arc A770. In practical terms, the RTX 4070 is a 1440p medium / 1080p ultra card while the Arc A770 targets 1080p high. The RTX 4070 also has 12GB of GDDR6X on a 192-bit bus, giving it more headroom for high-res textures and future titles.
Which is the better value, RTX 4070 or Arc A770?
The RTX 4070 costs $200 more (57% premium) but delivers roughly 57% better performance, making the upgrade worthwhile if your budget allows it. Our value scores reflect this: RTX 4070 gets 65/100 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 4070 justifies its price for demanding workloads.
Can the RTX 4070 or Arc A770 run games at 4K?
Neither card is an ideal 4K GPU. The RTX 4070 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.
RTX 4070 vs Arc A770 for 1440p gaming -- which is better?
At 1440p, the RTX 4070 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 4070 is the safer choice.
What CPU should I pair with the RTX 4070 or Arc A770?
To avoid bottlenecking the RTX 4070 (gaming score 47/100), pair it with at least a Ryzen 5 7600 or Ryzen 5 9600X. 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 4070 worth it in 2026?
The RTX 4070 remains a solid buy in 2026. With 12GB of GDDR6X and Ada Lovelace architecture, it handles current games at 1440p medium / 1080p ultra settings without issues. Support for DLSS 3.5 extends its lifespan further by boosting frame rates in supported titles. At $549 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 RTX 4070 vs Arc A770 use?
The Arc A770 draws 225W TDP versus 200W for the RTX 4070, 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 RTX 4070 uses a 1x 8-pin connector while the Arc A770 needs 2x 8-pin.
How many FPS can I expect from the RTX 4070 vs Arc A770?
Exact FPS varies by game and settings, but based on our gaming benchmark scores (RTX 4070: 47/100, Arc A770: 30/100), the RTX 4070 typically delivers 57% more frames than the Arc A770 at the same resolution and settings. In popular titles at 1440p or 1080p, the RTX 4070 with its 29.1 TFLOPS of compute power and 504 GB/s memory bandwidth pushes well above 60 FPS. Enabling DLSS 3.5 upscaling can boost that by another 30-50% with minimal visual quality loss.
