Key Differences
-
The RTX 5080 has 28% more theoretical FP32 compute
The RTX 5080’s 56.3 TFLOPS leaves the RTX 5070 Ti’s 43.9 TFLOPS well behind, so if this spec matters to you, the choice is easy. Architectures use their compute differently, so treat the gap as a guide and look at game benchmarks for the details.
-
The RTX 5080 has 20% more shader units
Not a close call. The RTX 5080 lists 10,752 and the RTX 5070 Ti lists 8,960. That’s a substantial gap. Treat shader count as a strong hint about performance tier, then check benchmarks for the games you actually play.
-
The RTX 5070 Ti has 60 W lower board power
Among all the differences on this page, 300 W against 360 W is one of the most meaningful, and it favors the RTX 5070 Ti. The RTX 5070 Ti draws less power, which makes it easier to cool in compact cases.
-
The RTX 5080 has 20% more ray tracing units
The RTX 5070 Ti gives up a lot on ray tracing units: 70, compared with 84 on the RTX 5080. Ray tracing units differ between generations and brands, so the count matters most within the same family.
-
The RTX 5080 has 7.1% more memory bandwidth
Don’t expect a night-and-day difference here. 960 GB/s against 896 GB/s is a small but genuine lead for the RTX 5080. Bandwidth needs vary by architecture, so compare it alongside VRAM and cache rather than on its own.
-
The RTX 5070 Ti has a smaller 750 W PSU requirement
The RTX 5070 Ti nudges ahead with 750 W, while the RTX 5080 lists 850 W. With the RTX 5070 Ti, you’re more likely to keep your existing power supply, which can save real money.

GPU & Performance
RTX 5080 leads
In the gpu & performance category, the RTX 5080 isn’t just ahead; it’s clearly ahead. The RTX 5080 brings 28% more theoretical FP32 compute. The RTX 5080 has more theoretical compute, which often, but not always, translates into higher frame rates. If this section decides it for you, choose the RTX 5080.
FP32 compute
RTX 5070 Ti: 43.9 TFLOPS RTX 5080: 56.3 TFLOPS FP32 compute is a theoretical peak that combines shader count and clock speed, a quick way to size up raw power.
Shader units
RTX 5070 Ti: 8,960 RTX 5080: 10,752 Shader units do most of the heavy lifting in games, so more of them usually means more frames per second within the same architecture.
Memory
RTX 5080 leads
The RTX 5080 takes memory by a nose. The RTX 5080 steps ahead thanks to 7.1% more memory bandwidth. The RTX 5080 has more bandwidth to work with, helping it hold up in memory-heavy games. In short, the RTX 5080 is the better-equipped card for memory.
Memory bandwidth
RTX 5070 Ti: 896 GB/s RTX 5080: 960 GB/s Memory bandwidth decides how quickly the GPU can feed itself with data, which matters most at 1440p and 4K.
Features
The features entries below are descriptive rather than numeric. Read them side by side to see where the RTX 5070 Ti and the RTX 5080 part ways.
Power & Thermals
RTX 5070 Ti leads
This is one of the RTX 5070 Ti’s strongest areas. On power & thermals, the RTX 5080 falls well short. Choose the RTX 5070 Ti and you get 60 W lower board power. Higher board power often comes with higher performance, so the RTX 5080’s appetite may be part of the price of its speed. Weighing only power & thermals, the RTX 5070 Ti comes out ahead.
Total board power
RTX 5070 Ti: 300 W RTX 5080: 360 W Lower board power means less heat, quieter cooling and a smaller impact on your electricity bill.
Recommended PSU
RTX 5070 Ti: 750 W RTX 5080: 850 W Recommendations include a safety margin for the rest of the system, so they’re a guide rather than a hard limit.
