Key Differences
-
The RTX 4080 Super has 53% more theoretical FP32 compute
Put simply, the RTX 4080 Super is far ahead here: 52.2 TFLOPS compared with 34.1 TFLOPS. The RTX 4080 Super has more theoretical compute, which often, but not always, translates into higher frame rates.
-
The RTX 4080 Super has 4 GB more VRAM
The RTX 4080 Super’s 16 GB leaves the RTX 3080 Ti’s 12 GB well behind, so if this spec matters to you, the choice is easy. Newer games tend to ask for more video memory, so the RTX 4080 Super’s extra VRAM helps the card age better.
-
The RTX 3080 Ti has 24% more memory bandwidth
Not a close call. The RTX 3080 Ti lists 912 GB/s and the RTX 4080 Super lists 736 GB/s. That’s a substantial gap. Memory bandwidth decides how quickly the GPU can feed itself with data, which matters most at 1440p and 4K.
-
The RTX 4080 Super has 30 W lower board power
Don’t expect a night-and-day difference here. 320 W against 350 W is a small but genuine lead for the RTX 4080 Super. Lower board power means less heat, quieter cooling and a smaller impact on your electricity bill.
-
The RTX 4080 Super has a 53% higher boost clock
Among all the differences on this page, 2,550 MHz against 1,665 MHz is one of the most meaningful, and it favors the RTX 4080 Super. Clock speeds are only comparable within similar architectures; across generations, they tell you less.

GPU & Performance
RTX 4080 Super leads
This section belongs to the RTX 4080 Super. In gpu & performance, it leads the RTX 3080 Ti by a margin that’s hard to ignore. The RTX 4080 Super takes this one with 53% more theoretical FP32 compute. Architectures use their compute differently, so treat the gap as a guide and look at game benchmarks for the details. For gpu & performance, the RTX 4080 Super is the one to beat.
FP32 compute
RTX 3080 Ti: 34.1 TFLOPS RTX 4080 Super: 52.2 TFLOPS FP32 compute is a theoretical peak that combines shader count and clock speed, a quick way to size up raw power.
Boost clock
RTX 3080 Ti: 1,665 MHz RTX 4080 Super: 2,550 MHz A higher boost clock means the GPU runs faster when it has thermal and power headroom.
Memory
Trade-off
In the memory category, the RTX 3080 Ti counts 24% more memory bandwidth in its favor, and the RTX 4080 Super answers with 4 GB more VRAM. Which card wins on memory depends on which of those strengths you’ll actually use.
VRAM
RTX 3080 Ti: 12 GB RTX 4080 Super: 16 GB At high resolutions or with texture packs, running out of VRAM can hurt more than a small speed gap.
Memory bandwidth
RTX 3080 Ti: 912 GB/s RTX 4080 Super: 736 GB/s The RTX 3080 Ti has more bandwidth to work with, helping it hold up in memory-heavy games.
Features
For features, the differences are in the specifics (component names and types), so the table is the place to look.
Power & Thermals
RTX 4080 Super leads
On power & thermals, the difference is modest, and it favors the RTX 4080 Super. The RTX 4080 Super makes its case with 30 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 4080 Super is the card to pick.
Total board power
RTX 3080 Ti: 350 W RTX 4080 Super: 320 W The RTX 4080 Super draws less power, which makes it easier to cool in compact cases.
