AMD launched its new second-gen EPYC Rome CPUs a few months ago and now we're getting more details on the chip itself, and just how many transistors it is packed with -- something that is quite amazing to behold.
The new second-gen EPYC Rome CPUs have had some gorgeous up-close die shots courtesy of the folks at Hardwareluxx, where we get some ridiculously detailed images of the 9-die design (which is known as an MCM, or multi-chip module).
We now know that the AMD second-gen EPYC Rome processors pack a total of 39.54 billion transistors, which is kinda mind blowing. To compare this to NVIDIA's flagship TITAN RTX graphics card, which packs 18.6 billion -- AMD is doing some magic here with Zen 2, the 7nm node, and EPYC Rome CPUs with nearly 40 billion transistors.
The 9 dies inside of the EPYC Rome CPUs pack 8 x CCDs (Compute Core dies) and a single IOD (input/output die). Each of the CCDs have 2 x CCXs (Compute Core complexes) that each pack 4 x Zen 2 cores with their own L2 cache and shared L3 cache. Each of the 8 x CCDs are connected to the I/O through AMD's in-house Infinity Fabric technology.
