AMD EPYC 7773X "Milan-X" Benchmarks Show Very Strong HPC Performance Upgrade
Compared to the AMD briefings focusing on just a few particular workloads (and with that mostly proprietary applications), it was good seeing a fairly robust array of software packages benefiting from the 3D V-Cache.
But for general purpose workloads like say code compilation, the gains from the large cache are much smaller to in some workloads no measurable difference.
There was not a significant difference in the overall AC system power consumption when toggling 3D V-Cache from the BIOS. In fact, with 3D V-Cache enabled the system power consumption was ~11 Watts less on average, possibly due to the increased L3 cache hit rate and thus not needing to go out to the DDR4 system memory as often.
The combined CPU power consumption also had an average showing the 3D V-Cache enabled mode to be slightly more efficient, again by about ~12 Watts for the EPYC 7773X 2P configuration.
When looking at the CPU0 temperatures over the course of all the runs, there wasn't any significant difference there.
