Key Differences
-
The RTX 3080 Ti has 154% more theoretical FP32 compute
Big gap, real consequences. The RTX 3080 Ti’s 34.1 TFLOPS versus the RTX 2080 Ti’s 13.4 TFLOPS changes how the two compare in daily use. FP32 compute is a theoretical peak that combines shader count and clock speed, a quick way to size up raw power.
-
The RTX 3080 Ti has 135% more shader units
The RTX 2080 Ti is clearly behind on shader units (4,352 against 10,240), and that’s one of its biggest weak spots in this matchup. Treat shader count as a strong hint about performance tier, then check benchmarks for the games you actually play.
-
The RTX 2080 Ti has 100 W lower board power
On this line of the spec sheet, the RTX 2080 Ti is in a different league: 250 W, next to 350 W for the RTX 3080 Ti. The RTX 2080 Ti draws less power, which makes it easier to cool in compact cases.
-
The RTX 3080 Ti has 48% more memory bandwidth
For memory bandwidth, the RTX 3080 Ti leads by a wide margin: 912 GB/s versus 616 GB/s. Bandwidth needs vary by architecture, so compare it alongside VRAM and cache rather than on its own.
-
The RTX 3080 Ti has 18% more ray tracing units
This is a headline difference. With 80 to the RTX 2080 Ti’s 68, the RTX 3080 Ti has a lead that’s easy to see on paper and in practice. If you enable ray tracing, the RTX 3080 Ti’s extra RT hardware should take less of a hit.

GPU & Performance
RTX 3080 Ti leads
Few areas are as clear-cut as this one: the RTX 3080 Ti leads the gpu & performance section with room to spare. The RTX 3080 Ti stands out with 154% more theoretical FP32 compute. The RTX 3080 Ti has more theoretical compute, which often, but not always, translates into higher frame rates. Net result: the RTX 3080 Ti leads this part of the comparison.
FP32 compute
RTX 2080 Ti: 13.4 TFLOPS RTX 3080 Ti: 34.1 TFLOPS Architectures use their compute differently, so treat the gap as a guide and look at game benchmarks for the details.
Shader units
RTX 2080 Ti: 4,352 RTX 3080 Ti: 10,240 The RTX 3080 Ti’s extra shaders give it more raw muscle, although comparisons across different architectures aren’t one-to-one.
Memory
RTX 3080 Ti leads
For memory, the verdict is easy: the RTX 3080 Ti leads, and not by a little. On its side, the RTX 3080 Ti has 48% more memory bandwidth. The RTX 3080 Ti has more bandwidth to work with, helping it hold up in memory-heavy games. On memory alone, the RTX 3080 Ti gets the nod.
Memory bandwidth
RTX 2080 Ti: 616 GB/s RTX 3080 Ti: 912 GB/s Memory bandwidth decides how quickly the GPU can feed itself with data, which matters most at 1440p and 4K.
Features
On features, the useful details are the names in the table: what each one uses, not a figure we can rank.
Power & Thermals
RTX 2080 Ti leads
The RTX 3080 Ti is outclassed on power & thermals; the RTX 2080 Ti leads by a clear margin. Choose the RTX 2080 Ti and you get 100 W lower board power. Higher board power often comes with higher performance, so the RTX 3080 Ti’s appetite may be part of the price of its speed. If power & thermals is your priority, the RTX 2080 Ti is the card to pick.
Total board power
RTX 2080 Ti: 250 W RTX 3080 Ti: 350 W Lower board power means less heat, quieter cooling and a smaller impact on your electricity bill.
Recommended PSU
RTX 2080 Ti: 650 W RTX 3080 Ti: 750 W The recommended power supply tells you whether your current PSU can handle the card without an upgrade.
