NVIDIA GeForce RTX 3090 Ti is based on the 2nd gen RTX architecture Ampere architecture, manufactured on Samsung 8N same as the rest of the RTX 30 Series. The GeForce RTX 3090 Ti uses the GA102-350 silicon, while comparatively, the GeForce RTX 3090 is GA102-300 silicon. The RTX 3090 Ti utilizes all 84 SMs, and 10,752 CUDA Cores, while the RTX 3090 uses 80 SMs and 10,496 CUDA Cores. The RTX 3090 Ti has 84 Ray Tracing Cores and 336 Tensor Cores, while the RTX 3090 has 82 RT Cores and 328 Tensor Cores. The RTX 3090 Ti has 112 ROPs and 336 TMUs while the RTX 3090 has 112 ROPs and 328 TMUs. Therefore, as you can see the RTX 3090 Ti has a bit more CUDA Cores, a couple more RT Cores, a bit more Tensor Cores, and the same number of ROPs.

For clock speeds, the GeForce RTX 3090 Ti has a base clock of 1560MHz and a Boost Clock of 1860MHz. The GeForce RTX 3090 has a base clock of 1395MHz and a Boost Clock of 1695MHz. Therefore, the new RTX 3090 Ti has a much-improved GPU clock speed, they really brought it up from 1695MHz to 1860MHz, an increase of 10% higher clock frequency, which can make a difference for sure.

NVIDIA also gave the GeForce RTX 3090 Ti even faster memory, still using 24GB of GDDR6X but now running at 21GHz versus 19.5GHz on the RTX 3090. That brings the memory bandwidth now to over 1TBs, while it was 935GB/s on the RTX 3090.

All of this means a higher TDP, to push these features and clock speed NVIDIA gave the GeForce RTX 3090 Ti a 450W TDP which is way up from the 350W TDP of the RTX 3090. That’s a fairly large increase in TDP, and as such the recommended PSU is 800W and it will require 3x 8-pin power connectors.
