Amd third generation epyc Xiaolong processor released: up to 64 cores, 19% IPC u

March 15 news today, amd released the third generation epyc (Xiaolong) processor "Milan", which adopts the latest Zen 3 architecture and 7Nm technology, with up to 64 cores and 128 threads, achieving a 19% intergenerational IPC improvement. Amd said that "Milan" has realized the access of 32MB L3 cache per core, memory interleaving has also increased the 6-channel mode on the basis of the previous generation of 4 / 8 channels, and the security features have been further enhanced. In addition, the third-generation epyc of AMD can be compatible with the second-generation platform, just need to update the BIOS.

AMD's third-generation epyc "Milan" has brought 19% increase in IPC. In terms of instruction set, "Milan" extends avx2 instruction to 256 bits, and greatly enhances the security and stability of the system.

In terms of memory interleaving, AMD's third-generation epyc "Milan" adds a 6-channel mode on the basis of the previous generation's support for 4 / 8-channel ddr4-3200 memory, which can give customers more flexibility and optimize the cost of memory.
In terms of security, AMD's third generation epyc "Milan" adopts amd secure processor technology integrated with SOC. In addition, amd also provides encryption function for key generation and management, and enables the startup of hardware verification, which can realize platform security based on hardware trust“ "Milan" also adds shadow stack and SNP security nested paging technology, which can increase the protection against control flow attacks. SNP can target some virtual machine programs that visitors have the right to log in to prevent them from malicious attacks.
Performance improvement
According to the official test of AMD, the third generation epyc "Milan" 32 core and above products have a very strong advantage over Intel 28 core Xeon gold 6258r in terms of single core performance, overall performance and thread density. Compared with Intel's 16 core supremacy silver 4216, AMD's third generation epyc "Milan" 16 core and above products also have great advantages.
