AMD Big Navi to have 5120 cores and 24GB HBM2e?

Take it with a grain of salt but some new Big Navi rumors are making the rounds. A Twitter user claims he received some specifications of Big Navi from a contact at SK Hynix. According to the leak, the upcoming Big Navi GPU from AMD will feature 5120 shader processors, 320 TMUs, 96 ROPs, 80 CUs, 24GB HBM2E memory from SK Hynix, and 2048GB/s memory bandwidth.

Surprisingly, the document lists the complete GPU and memory configurations. For the GPU itself, we are looking at 5120 stream processors packed in 80 Compute Units. The GPU consists of a total of 320 TMUs and 96 ROPs. The L2 cache size on the chip also sits at a mammoth 12 MB. That's 2x the cache of NVIDIA's flagship Tesla V100 GPU and Titan RTX. It's also 3x the cache size over AMD's own Radeon RX 5700 XT which is based on the Navi 10 GPU. There are no clock speeds mentioned for this part but the memory configuration is listed.

According to other rumors, AMD may talk about this chip in March so we may find out soon if there's any truth to this.

@ghost_motley @KOMACHI_ENSAKA Didn’t know where else to send this. One of my contacts in SK sent to me. Looks like a new GPU? pic.twitter.com/MEIc8smAZS
