EPYC “Genoa” based on Zen 4 architecture are still months away from appearing on the server processor market. However, the company with the three acronyms has just presented its AMD EPYC Milan-X. An improved version of their CPUs with Zen 3 architecture to which they have added the V-Cache. That surely adds a performance boost even when playing THABET casino games online. What are the first models and what is their performance?
One of the biggest challenges facing the performance of a CPU is precisely the enormous distance with RAM memory, which causes a latency that often becomes not tens, but hundreds and even thousands of clock cycles lost per waiting for her A solution to this is cache memories, which allow the processor to access a copy of the data from RAM in its internal memory and have it much sooner.
However, the memory that we can put inside a chip is limited by space. Well, as you already know by now, AMD has found the solution, putting it on top of the processor to increase the last level cache of its processors: an idea that they have baptized as V-Cache and in which the AMD EPYC Milan-X are built to boost performance on these server CPUs based on their 3rd generation Zen architecture. Processor Users Manuals are documents provided to users that help in using a particular system, product or service seamlessly. Thus, they should help users to get more out of such processors.
This is the AMD EPYC Milan-X range
The idea behind Milan-X is simple, place in each of the CCD Chiplets the so-called V-Cache so that the total size of the L3 cache in the processor reaches up to 768 MB per full processor in its maximum configuration of 64 cores or 8 processing chiplets with Zen 3 architecture. In other words, it is the same variant of its Zen 3 cores used in the Ryzen 7 5800X3D.
Each of the processors is compatible with the same sockets as the previous EPYC Milan and comes in several configurations ranging from 16 cores with a base speed of 3.5 GHz and a Boost of 4 GHz to the most complex model with 64 cores running at 2.2. GHZ and with peaks of up to 3.5 GHz. All accompanied by 8 channels of DDR4-3200 memory and a TDP ranging from 240 W to 280 W. So you will not be able to install them on the motherboards for your AMD Ryzen. Although we don’t think you’re looking forward to it either, since the cheapest of these processors costs $3,521 and the most expensive goes for over $8,000.
As for their performance, their greater amount of L3 cache compared to the standard EPYC Milan allows them to have higher performance, since the increase in cache partially solves the problem of latency to memory. According to AMD itself we can see performance increases ranging from 19% in WRF with 8 active virtual machines to 78% with Ansys Fluent with 64 virtual machines in total. So that’s a hefty performance boost for Intel’s Xeon Sapphire Rapids to outperform.
