Only a few differences between the 10GB and 12GB RTX 3080 variants. These differences improve performance slightly. Nvidia provided more than just extra VRAM to the RTX 3080 12GB. The two graphic cards share many similarities. Nvidia’s September 2020 Ampere architecture powers both cards. Both use the same 8nm Samsung node and design.

Core Clock And Boost Clock

Compared to the 12GB variant, the 10GB RTX 3080 should have fewer features. Not exactly. The lower VRAM model leads to some specifications. RTX 3080 10GB has a 1440 MHz core frequency, whereas the 12GB version has 1260 MHz.

This is critical when comparing two graphic cards like we are now. The RTX 3080 10GB excels in increasing game FPS. Both GPUs have 1710 MHz boost clocks.

Memory And Memory Bandwidth

Memory or VRAM is the main difference between the cards. We offer GDDR6X-based 10GB and 12GB models. The RTX 3070’s GDDR6 memory was slower and used more power.

The RTX 3080 12GB has 912.4 GB/s memory bandwidth and more VRAM than the 10GB version, which has 760.3. The RTX 3080 12GB’s faster VRAM-to-core data transmission compensates for the 10GB’s higher core clock.

Memory Clock And Memory Bus

Both GPUs have the same memory clock but different memory bandwidths. Memory clocks are VRAM speeds. Both cards transfer 19GB/s at 1188 MHz. The memory bus is another way to calculate memory bandwidth, which measures GPU data flow. The RTX 3080 12GB’s 384-bit memory bus beats the 10GB’s 320-bit. After considering all memory considerations, this does increase FPS.

RT Cores, CUDA Cores, And Tensor Cores

Nvidia GPUs have RT cores for Ray Tracing. These cores expedite the mathematical operations needed to trace light to create a realistic scene virtually, hence the term “Ray Tracing.” The 10GB and 12GB RTX 3080s have 68 and 70 RT cores, respectively. CUDA and Tensor cores do complicated calculations like RT cores. CUDA cores are more accurate than Tensor cores.
