RTX 5070 vs RTX 5070 Ti: Which Should You Buy?
Head-to-head on performance, VRAM, power and value for 2026.
Quick Summary · TL;DR
On our relative performance index the RTX 5070 Ti leads the RTX 5070 by about 15% — a moderate gap. The RTX 5070 Ti has more VRAM (16GB vs 12GB), which helps at high resolutions and in VRAM-hungry titles.

Which should you buy?
Buy the RTX 5070 Ti if you want the higher frame rate and can find it at a fair price. Choose the RTX 5070 if it is clearly cheaper and its 12GB+ of VRAM and features cover your target resolution. Both are from a similar lineage, so price is the main deciding factor.

RTX 5070 vs RTX 5070 Ti at each resolution
| Resolution | RTX 5070 | RTX 5070 Ti |
|---|---|---|
| 1080p | Excellent | Excellent |
| 1440p | Great (10 short of Excellent) | Excellent |
| 4K | Good (10 short of Great) | Great (10 short of Excellent) |
The 10-point gap (66 vs 76) changes the verdict at 1440p and 4K: that is where the RTX 5070 Ti earns its place. At 1080p both get the same rating, so paying for the faster card buys headroom rather than a different experience there. The RTX 5070 Ti also carries 4GB more memory (16GB vs 12GB).
Power, PSU and efficiency
Reference board power is 250W for the RTX 5070 and 300W for the RTX 5070 Ti, a 50W difference. Per 100W that works out to 26.4 index points for the RTX 5070 and 25.3 for the RTX 5070 Ti, so the RTX 5070 does more per watt. An existing 650W supply meets the maker guidance for the RTX 5070 but not for the RTX 5070 Ti (750W). Full sizing: RTX 5070 PSU · RTX 5070 Ti PSU.

Frequently asked questions
Is the RTX 5070 better than the RTX 5070 Ti?
On our relative index the RTX 5070 Ti is about 15% ahead of the RTX 5070. The RTX 5070 Ti has more VRAM (16GB vs 12GB), which helps at high resolutions and in VRAM-hungry titles. The smaller the gap, the more other factors like price, VRAM and features should decide it.
Which is better value, the RTX 5070 or the RTX 5070 Ti?
Value depends on the price you can find each at. The slower card is usually the smart buy if it is meaningfully cheaper, unless you need the extra VRAM or features of the faster one.
Do the RTX 5070 and RTX 5070 Ti need different power supplies?
The RTX 5070's maker lists a 650W supply and the RTX 5070 Ti's lists 750W; our starting classes are 650W and 750W. If you might move to the RTX 5070 Ti later, size for its 750W now. The RTX 5070 and RTX 5070 Ti can also take a PCIe Gen 5 (12V-2x6) cable; see the connector guide.
