You do get faster memory too, with 10GB of GDDR6X memory, running across an aggregated 320-bit memory interface. It is though a larger slice of silicon than the TU104 which powered the equivalent level card of the last generation, the RTX 2080.Ī side-by-side look at the Boost clock speed of the RTX 3080 compared with the RTX 2080 Super might have you worrying for the performance of the GPU as it rated slower, but in our testing we've clock speeds well north of 1,800MHz as standard-at a similar level to the last-gen Turing card. That's smaller than the top Turing chip, which was 754mm2, but packs in another 10 billion transistors at 28.3 billion transistors. The GeForce RTX 3080 GPU is built on the Samsung 8N design, which is nominally an 8nm production node, with a die size of 628.4mm2. Because of the way the new architecture is designed, however, you do get fewer AI-driving Tensor Cores. These cores are arrayed across 68 streaming multiprocessors (SMs), which means that you get a few more of the dedicated 2nd gen RT Cores too. Although that kinda depends on your definition of a 'core'. That is still a huge increase over the paltry 3,072 CUDA cores Nvidia released the RTX 2080 Super with just last year.
The cut-down version dropped into the RTX 3080, however, sports 8,704.

The full GA102 GPU, the same essential chip which powers both the RTX 3080 and the upcoming RTX 3090, houses 10,752 CUDA cores. That's down to the redesigned data paths Nvidia has fitted into the GA102 silicon at the heart of the RTX 3080. We're seeing effectively twice the number of cores compared to what we were expecting, and far more than the equivalent GPU of the previous Turing generation. The key specs, most especially when it comes to gaming, are those heavily beefed up CUDA core numbers.
