Epic AMD EPYC 7002 Cover 6 Chips

AMD this morning launched two new processors, the AMD EPYC 7662 and EPYC 7532. The EPYC 7662 is a 64-core part while the EPYC 7532 is a 32-core part. This also marks the company filling out an SKU stack from a relatively smaller number of models.

AMD EPYC 7662 Overview

The AMD EPYC 7662 is a 64-core and 128-thread processor with 256MB of L3 cache. The chip has a TDP of 225W matching the highest-end mainstream (e.g. non- EPYC 7H12) CPUs.

This SKU is interesting since it seems to be an alternative to the EPYC 7702 series of processors offering a higher TDP to let the cores stay at turbo clocks longer than the launch part. We can see why some customers wanted another option since the 64-core parts are currently unique to AMD. AMD claims they have five SKUs, however, one is the EPYC 7702P a single socket only version of the EPYC 7702. AMD seems to be differentiating their stack at that 64-core level.

AMD EPYC 7532 Overview

The AMD EPYC 7532 is a 32-core and 64-thread processor with 256MB of L3 cache. The chip has a TDP of 200W. That means that this chip, like the 64-core EPYC 7662, is an eight CCD design. In other words, it has eight chiplets that are attached to the central I/O die. Each has 4 cores and 32MB of L3 cache active per chiplet.

AMD is focusing this part on applications such as ANSYS CFX that are cache intensive. With the EPYC 7532, each core gets 8MB of cache. When one compares these EPYC chips to Intel Xeon, AMD simply has significantly more cache per core.

Here is what the new SKU stack looks like with these additions:

As you can see, the SKU numbers are becoming challenging to see in a linear fashion with the EPYC 7662 looking like it may be a match for the EPYC 7702. We are also noting that with these new parts, AMD is not using a low cTDP figure and is simply presenting one number. Perhaps this is AMD trying to simplify how they go to market with their chips.

Some may think that these are the VMware optimized SKUs mentioned in our Licenseageddon Rages as VMware Overhauls Per-Socket Licensing piece. We think that a 225W version of the EPYC 7532 will be what that chip eventually looks like. Still, for some organizations optimizing around 32-core license sets, this gives another option.

AMD says that Dell and Supermicro will now offer the two new SKUs while HPE and Lenovo will follow. We requested list pricing and will update this piece when we get it.
