One of the cuts, unjustified for us, that Intel has made in its processors is to eliminate the support for AVX-512 instructions on your Intel Core 12. They did this in the second batch with the intent that the Sapphire Rapids-based Intel Xeon would have exclusive use of these units. However, if you are interested in a processor that supports them, we will tell you how to identify them.
One commonality between fourth-generation Intel Core 12 and Xeon Scalable processors is the use of Golden Cove cores, which are given the trade name P-Cores and are symmetrical from processor to processor. So both have AVX-512 units. However, Intel faced with the second shipment of its chips decided to eliminate this capability.
However, there are applications that are optimized to use these instructions and therefore gain execution speed by using them, so the fact that they have been lost in newer processors is a major loss on Intel’s part. . Doubly, if you take into account that AMD is going to adopt them in Ryzen 7000 due to the fact that they will be adopted in Zen 4 cores. In any case, we predict that if you are going to buy a boxed processor of the store, we warn you that all those who have the unlocked slogan
How to detect if your Intel Core 12 supports AVX-512
There are several ways to find out if your Intel Core 12 supports the so-called Advanced Vector Extensions in its 512-bit version. So we’ll start with the serial number that came with the processor. The first payments into your the serial number starts with V149 or X149 above and will therefore have the ability to execute AVX-512 instructions. Instead, newer ones with serial numbers V202 or X202 have them completely disconnected. Where can we have doubts? If the code printed on our GPU package changes from V150 or X150 to V201 or X201, then in this case it will be a lottery.
The other important thing you will need to check for AVX-512 instruction support on your Intel Core 12 is the CPU control unit firmware. You can do this with apps like HWInfo64 where is it is listed as MCU. In case you find the version is 0x16 or earlierthen it will mean that AVX-512 support is assured on your Intel Core 12, but still, there is one last point that you will need to check what your motherboard BIOS is.
Let’s not forget that to enable the use of AVX-512 instructions we must perform a process of disabling the E-Cores through the BIOS and not all of them have this ability. So you may have the right processor and firmware, but that capability may not be included on your motherboard.
