4/7/2023 0 Comments Intel tick tock![]() Additional improvements include a non-inclusive last-level cache, a larger 1MB L2 cache, faster 2666 MHz DDR4 memory, an increase to six memory channels per CPU, new memory protection features, Intel® Speed Shift Technology, on-die PMAX detection, integrated Fabric via Cornelis Networks, Internet Wide Area RDMA Protocol (iWARP)*, Intel® Virtual RAID on CPU (Intel® VROC), and more. The Intel Xeon processor Scalable family on the Purley platform provides up to 28 cores, which bring additional computing power to the table compared to the 22 cores of its predecessor. Block Diagram of the Intel® Xeon® processor Scalable family microarchitecture. Intel® Xeon® processor Scalable family Microarchitecture Overviewįigure 3. This paper discusses the new features and enhancements available in Intel Xeon processor Scalable family and what developers need to do to take advantage of them. All available features are available across the entire range of processor socket count (two through eight) at the platinum level. The bronze level has the least amount of features and as you move towards platinum more features are added. New branding for processor models.Ī two-socket Intel Xeon processor Scalable family configuration can be found within all the levels of bronze through platinum, while a four-socket configuration will only be found at the gold through platinum levels, and the eight-socket configuration will only be found at the platinum level. They are Intel’s platform of choice for the most scalable and reliable performance with the greatest variety of features and integrations designed to meet the needs of the widest variety of workloads.įigure 2. The processors from Intel Xeon processor Scalable family are scalable from a two-socket configuration to an eight-socket configuration. One of the big changes with the Intel Xeon processor Scalable family is that it includes all the processor models associated with this new generation. In previous generations two and four socket processor families were segregated into different product lines. These features include increased processor cores, increased memory bandwidth, non-inclusive cache, Intel® Advanced Vector Extensions 512 (Intel® AVX-512), Intel® Memory Protection Extensions (Intel® MPX), Intel® Ultra Path Interconnect (Intel® UPI), and sub-NUMA clusters. ![]() Intel Xeon processor Scalable family on the Purley platform is a new microarchitecture with many additional features compared to the previous-generation Intel® Xeon® processor E5-2600 v4 product family (formerly Broadwell microarchitecture). Major architecture changes take place on a “tock,” while minor architecture changes and a die shrink occur on a “tick.” The new generation, the Intel® Xeon® processor Scalable family (formerly code-named Skylake-SP), is a “tock” based on 14nm process technology. Intel uses a tick-tock model associated with its generation of processors. ![]()
