RTX 4080 vs RTX 5070 Ti
The RTX 4080 and the RTX 5070 Ti share their roots, so the useful question isn’t which is “good” but where each one differs. Both have a headline advantage (gpu & performance for the RTX 4080, memory for the RTX 5070 Ti), so the right choice depends on how you’ll use it. That $450 launch price gap between the RTX 4080 and the RTX 5070 Ti will shape the verdict as much as any spec.

Key Differences
-
The RTX 5070 Ti has 25% more memory bandwidth
The numbers aren’t close. The RTX 5070 Ti lists 896 GB/s for memory bandwidth, while the RTX 4080 lists 717 GB/s. The RTX 5070 Ti has more bandwidth to work with, helping it hold up in memory-heavy games.
-
The RTX 4080 has 11% more theoretical FP32 compute
A narrow win for the RTX 4080. With 48.7 TFLOPS to 43.9 TFLOPS, it’s the kind of difference that adds up rather than stands out. The RTX 4080 has more theoretical compute, which often, but not always, translates into higher frame rates.
-
The RTX 4080 has 8.6% more shader units
Close, but not identical: the RTX 4080 lists 9,728 and the RTX 5070 Ti lists 8,960. Treat shader count as a strong hint about performance tier, then check benchmarks for the games you actually play.
-
The RTX 5070 Ti has 20 W lower board power
The gap on total board power is slim (300 W against 320 W), yet it tips toward the RTX 5070 Ti. The RTX 5070 Ti draws less power, which makes it easier to cool in compact cases.
-
The RTX 4080 has 8.6% more ray tracing units
You may not notice this one every day, but the RTX 4080’s 76 is a step ahead of the RTX 5070 Ti’s 70. If you enable ray tracing, the RTX 4080’s extra RT hardware should take less of a hit.

GPU & Performance
RTX 4080 leads
The RTX 5070 Ti is outclassed on gpu & performance; the RTX 4080 leads by a clear margin. On its side, the RTX 4080 has 11% more theoretical FP32 compute. FP32 compute is a theoretical peak that combines shader count and clock speed, a quick way to size up raw power. The RTX 5070 Ti steps ahead thanks to. The takeaway: on gpu & performance, the RTX 4080 is the stronger card.
FP32 compute
RTX 4080: 48.7 TFLOPS RTX 5070 Ti: 43.9 TFLOPS Architectures use their compute differently, so treat the gap as a guide and look at game benchmarks for the details.
Shader units
RTX 4080: 9,728 RTX 5070 Ti: 8,960 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 5070 Ti leads
On memory, the gap between these two is wide, and it favors the RTX 5070 Ti. Point to the RTX 5070 Ti for 25% more memory bandwidth. Bandwidth needs vary by architecture, so compare it alongside VRAM and cache rather than on its own. If this section decides it for you, choose the RTX 5070 Ti.
Memory bandwidth
RTX 4080: 717 GB/s RTX 5070 Ti: 896 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 4080 and the RTX 5070 Ti part ways.
Power & Thermals
RTX 5070 Ti leads
Call it a small but real win for the RTX 5070 Ti in this area. The RTX 5070 Ti gives you 20 W lower board power. Higher board power often comes with higher performance, so the RTX 4080’s appetite may be part of the price of its speed. That makes the RTX 5070 Ti the natural choice for buyers focused on power & thermals.
Total board power
RTX 4080: 320 W RTX 5070 Ti: 300 W Lower board power means less heat, quieter cooling and a smaller impact on your electricity bill.
