With the GeForce Beyond event on Wednesday, the new generation RTX 4000 series graphics cards were introduced. Although NVIDIA talked about the details of the Ada Lovelace architecture, it briefly talked about its new GPUs. Fortunately, the production partners fill in the gaps with the information they provide.
Ada Lovelace is based on the TSMC 4N process customized for NVIDIA, offering higher AI, ray tracing and rendering performance compared to Ampere architecture. AD102, the largest of the GPU family, became the highest transistor consumer GPU with 76.3 billion transistors.
Also, the size of the GPU die measured 608.4 mm². This means a transistor density of 125.5 million per mm². In other words, 2.78 times higher transistor density was achieved than the GA102 (Ampere) GPU produced using Samsung’s 8N technology. To remind you again, a maximum of 18,432 CUDA cores can be used in AD102.
The island architecture features Shader Execution Reordering (SER), which speeds up rasterization operations and provides up to 25% better gaming performance. However, we mentioned that 3rd Generation RT Cores and 3rd Generation Tensor Cores are used in the new architecture. The new Tensor cores deliver 1400 TFLOPS of computational performance, 4.3 times greater than the cores used in the Ampere architecture.
- GeForce RTX 4090: AD102-300
- GeForce RTX 4080 16GB: AD103-300
- GeForce RTX 4080 12GB: AD104-400
GeForce RTX 4090 comes with AD102-300 GPU, which is a cropped variant of AD102. The RTX 4080 16GB model uses the AD103-300 GPU. The 12GB version, which replaces the RTX 4070, takes advantage of the smaller AD104-400 GPU.
