AD104 has more transistors than GA102
Recently, NVIDIA released the 4nm Ada Lovelace architecture GPU, and the first batch of three graphics cards, GeForce RTX 4090 / RTX 4080 16GB / RTX 4080 12GB, were launched, equipped with AD102, AD103, and AD104 chips respectively. Ryan Smith of AnandTech has full information on these chips.
The areas of AD102, AD103, and AD104 are 608mm², 378.6mm², and 294.5mm² respectively, and the corresponding transistor numbers are 76.3 billion, 45.9 billion, and 35.8 billion respectively. The transistor density of AD103 and AD104 is the same, and the transistor density of AD102 is slightly higher. In terms of quantity, AD104 has 7.5 billion more transistors than GA102.
To free up more space, Nvidia has made some architectural changes, such as removing NVLink on the Ada Lovelace architecture GPU. At the same time, the L2 cache of the Ada Lovelace architecture GPU has also undergone great changes, and the capacity has been significantly increased. The Ada Lovelace architecture uses the same TSMC (TSMC) 4N process as the Hopper architecture. According to the introduction of HKEPC, it is not the same as the generally considered N4 process, but a reduced version on the 5nm process node.
