According to VideoCardz, Nvidia has now released the complete information about the chip size and transistor count of AD102, AD103 and AD104 GPUs. According to VideoCardz
- AD102 (RTX 4090): 608 mm², 76.3 billion transistors
- AD103 (RTX 4080 16G): 378.6 mm², 45.9 billion transistors
- AD104 (RTX 4080 12G): 294.5 mm², 35.8 billion transistors
The new GPUs are reported to have transistor densities higher than 121 million per square millimeter. The AD104, with 35.8 billion transistors, has 7.5 billion more transistors than the previous flagship GA102 GPU.
In addition, the next-generation GPUs have far more rendering output units (ROPs) than their predecessors, with the AD102 at 192 ROPs, the AD103 at 112 ROPs, as many as the previous flagship GA102, and the AD103 at 80 ROPs. higher ROPs will improve rasterization performance.
The new generation GPUs also have improved L2 cache, with 96MB for the AD102, 64MB for the AD103, and 48MB for the AD104. NVIDIA has confirmed that both RTX 4080 models will have a 48MB L2 cache.
