NVIDIA's GeForce RTX 40 GPUs based on the Ada Lovelace graphics architecture have their SM configurations allegedly leak out, pointing out to over 18,000 cores for the flagship AD102 chip.

NVIDIA GeForce RTX 40 'Ada Lovelace' GPU Configurations Leak Out: AD102 With 144 SMs, AD103 With 84 SMs, AD104 With 60 SMs, AD106 With 36 SMs, AD107 With 24 SMs

Recently, NVIDIA got hacked and hackers were able to steal over 1 TB of confidential information which has started leaking out. Some information that has leaked out in the public already includes a bypass for the LHR technology, source code for DLSS technology, & codenames of next-gen GPU architectures. We have seen information regarding Hopper's successor, Blackwell, leak out that will feature at least two Data Center chips but this latest leak is specific to the consumer GPU lineup on the Ada Lovelace GPU architecture.

According to the leak, NVIDIA will have at least six GPUs within its Ada Lovelace lineup. These will include AD102, AD103, AD104, AD106, AD107, and AD10B. The first five SKUs will be designed for the desktop and mobility segments and featured in both GeForce RTX 40 and RTX Workstation solutions. The last part is reported by Kopite7kimi to be specific to the next-gen Tegra SOC while the Ampere-based GA10F could go on to power the next-gen Switch handheld console and Tegra Drive solutions.

So coming to the leaked SKUs, the top AD102 GPU which is likely going to power the next-gen GeForce RTX 4090, RTX 4080 Ti graphics cards will make use of 144 SMs, a 71% increase over the existing GA102 GPU and house a massive 18,432 CUDA core count. The interesting thing here is that the AD102 GPU is the only SKU that is getting over a 50% increase in SM count & considering what we have heard about the flagship chip, in terms of performance and power consumption, it looks very likely that NVIDIA is going all out with its top chip in the Ada Lovelace family.

The AD103 GPU will replace the GA103 GPU which was recently introduced on mobile and feature the same SM count as the GA102 GPU at 84. The AD104, AD106, and AD107 GPUs will feature 60, 36, and 24 SM units, respectively. Besides the AD103 GPU which is a 40% SM increase over GA103, every other GPU gets a 25-20% SM count increase over its predecessor. It's not as significant as the AD102 GPU but considering this is the mainstream segment, we are likely going to get RTX 3080 or similar performance out of an RTX 4060 Ti & RTX 3070 or higher performance out of the standard RTX 4060. The RTX 4050 should be close or on par with an RTX 3060 given the addition of IPC and clock improvements aside from architectural upgrades.

In addition to the SM counts, the Ada Lovelace GPUs will also feature increased L2 cache sizes. Starting with the AD102 GPU, the flagship would be outfitted with up to 96 MB of L2 cache, an insane 16x increase over the 6 MB L2 cache featured on GA102. The AD103 GPU will feature 64 MB, AD104 will feature 48 MB while both AD106/AD107 GPUs will feature 32 MB of L2 cache. As for the memory bus, the flagship AD102 GPU will feature a 384-bit bus interface, the AD103 GPU will get a 256-bit bus interface, AD104 will feature a 192-bit bus interface, while the AD106/AD107 GPUs will get a 128-bit bus interface.
