Greymon55 has shared new purported specifications for AMD and NVIDIA’s next flagship graphics cards. Among them are core counts; the AMD Radeon RX 7900 XT (RDNA 3) will supposedly feature 15,360 cores, while the NVIDIA GeForce RTX 4090 (Lovelace) will supposedly feature 18,432 cores. AMD and NVIDIA’s current flagships feature 5,120 cores and 10,496 cores, respectively.

5nm TSMC
144SM 18432CUDA
384bit 24G GDDR6X 21Gbps？
2.3~2.5GHz？
85~92T FP32？
From Wccftech’s coverage:
Performance-wise, the [Navi 31] GPU is expected to feature a clock speed of 2.4 – 2.5 GHz which puts its theoretical performance at around 75 TFLOPs (FP32). This is an insane 226% improvement vs a Radeon RX 6900 XT graphics card. […]
The NVIDIA AD102 “ADA GPU” appears to have 18432 CUDA Cores based on the preliminary specs (which can change), housed within 144 SM units. This is almost twice the cores present in Ampere which was already a massive step up from Turing. A 2.3-2.5 GHz clock speed would give us up to 85 to 92 TFLOPs of compute performance (FP32).
AMD and NVIDIA are expected to introduce these graphics cards next year. Navi 31, the GPU that will power the Radeon RX 7900 XT, will leverage a multi-chip module design.
