AMD EPYC Milan-X server CPU lineup will consist of four processors. The EPYC 7773X features 64 cores and 128 threads, the EPYC 7573X features 32 cores and 128 threads, the EPYC 7473X features 24 cores and 48 threads while the EPYC 7373X features 16 cores and 32 threads. The models along with their OPN codes are:

  • EPYC 7773X 64 Core (100-000000504)
  • EPYC 7573X 32 Core (100-000000506)
  • EPYC 7473X 24 Core (100-000000507)
  • EPYC 7373X 16 Core (100-000000508)

The flagship AMD EPYC 7773X will rock 64 cores, 128 threads and feature a maximum TDP of 280W. The clock speeds will be maintained at 2.2 GHz base and 3.5 GHz boost while the cache amount will drive up to an insane 768 MB. This includes the standard 256 MB of L3 cache that the chip features so essentially, we are looking at 512 MB coming from the stacked L3 SRAM which means that each Zen 3 CCD will feature 64 MB of L3 cache. That’s an insane 3x increase over the existing EPYC Milan CPUs. In terms of pricing, the EPYC 7773X costs $8800 US which is $1090 US higher than the MSRP of EPYC 7763, making it 12% more expensive than its predecessor.

The second model is the EPYC 7573X which features 32 cores and 64 threads with a 280W TDP. The base clock is maintained at 2.8 GHz and the boost clock is rated at up to 3.6 GHz. The total cache is 768 MB for this SKU too. Now interestingly, you don’t need to have 8 CCDs to reach 32 cores as that can be achieved with a 4 CCD SKU too but considering that you’d need double the amount of stack cache to reach 768 MB, that doesn’t look like a very economical option for AMD and hence, even the lower-core count SKUs might be featuring the full 8-CCD chips. The 7573X costs $5590 which is 15% more expensive than the $4860 US pricing of the EPYC 75F3.

With that said, we have the EPYC 7473X which is a 24 core and 48 thread variant with a 2.8 GHz base and 3.7 GHz boost clock and a TDP of 240W while the 16 core and 32 thread EPYC 7373X is configured at a 240W TDP with a base clock of 3.05 GHz and 3.8 GHz boost clock and  768 MB of cache. Both chips cost $3900 and $4185, respectively, which makes them 34 ($2900 74F3) & 267 ($1565 73F3) percent more expensive than their Non-X counterparts.

As for performance, AMD showcased a 66% performance uplift in RTL verifications with Milan-X versus the standard Milan CPU. A live demo showcased how Synopsys VCS Functional verification test was completed by Milan-X 16-core SKU much faster than the non-X 16 core SKU. We have also seen latency and bandwidth benchmarks for the Milan-X lineup which means that there are indeed use cases in the HPC segment for chips with such large cache designs. As a result, there will be a lot of customers who will be willing to pay the slight price difference to get access to almost 1 GB of cache per chip. The lineup is expected to launch tomorrow on 21st March.
