Detailed images of the GA102 GPU, which powers graphics cards such as RTX 3090 and RTX 3080, have been shared.Earlier, AMD’s Ryzen 5 5600X processor was broken down and we looked at what the Zen 3 architecture looked like.
We have the same name Fritzchens Fritz, but this time the GA102 GPU is on the table. To summarize, NVIDIA’s high-end graphics cards such as RTX 3080 and RTX 3090 use this GPU silicon. On the other hand, NVIDIA has the possibility to configure the same GPU according to the model.
Many PC users may be unaware of the graphics processor (GPU) inside their graphics card. Even if we see these GPUs, there is a cooler layer on the top. Let’s take a look at what the GA102 looks like with high resolution images.
GeForce RTX 3090 graphics card was used to produce high resolution images. The new GPUs do not have large IHS (Integrated Heat Spreader) as in the old. For this reason, the part on the processor was easily removed and the details were immediately revealed.
The uncropped GA102 GPU consists of 7 graphics processing clusters with 12 SM (Streaming Multiprocessors) units in each section. In the resulting 84 SMs, 10752 CUDA cores can be found. There is also 10 MB L1 and 6 MB L2 cache in the GPU. On the other hand, there are ROPs, TMUs, memory controllers and an NVLink I / O hub.
The unit, called SM, is divided into four processing blocks, each with 32 FP32 Cores, 16 INT32 Cores, a Tensor Core, a warp scheduler and a dispatch unit.
You can take a look at the work detailed by Locuza right below. Here, each part of the graphics processor is mapped and marked separately.
