![]() Genoa is available across 18 SKUs (14 2-socket and four 1-socket), ranging from 16 to 96 cores and consuming between 200 and 400 maximum watts. In benchmarking tests, the AVX-512 extensions provided a 4.2x boost for NLP throughput, a 3x boost for image classification and a 3.5x boost for object detection throughput, according to AMD.ĪMD highlighted gen-over-gen performance increases across HPC, cloud and enterprise workloads for the fourth-generation Epycs with a 123% boost for HPC workloads, represented by the SPECrate 2017_fp_base benchmark, with head-to-head comparisons from the top of the stack. This capability is targeted to heavy-lifting HPC applications like molecular simulation, ray tracing, physics simulations, and more, ” said Mark Papermaster, AMD’s chief technology officer. This is designed to prevent frequency fluctuations while you’re running AVX-512 workloads. “Our implementation uses a double pumped approach on a 256-bit data path. There are new AVX-512 instructions for Zen 4 that include per-lane masking capabilities, new Scatter/Gather instructions, BFloat16 instruction support and VNNI instruction support. Su reiterated that five of the top 10 most powerful supercomputers and eight of the top 10 most efficient supercomputers are using Epyc, including Frontier, the world’s first exascale supercomputer and its most energy-efficient. “With the third-gen Epyc, we’re already the world’s fastest supercomputing chip, and going to the fourth-gen Epyc, our leadership has delivered two-and-a-half times more performance than the competition,” said AMD CEO Lisa Su. On the SpecRate 2017-fb-base benchmark, the 96-core Genoa yielded roughly 2x better performance over the previous generation 64-core Epyc and about 2.5x better performance versus a 40-core Intel Ice Lake CPU-based server. For HPC, this translates into faster time to solutions. The fourth-gen Epyc chips – which tout more than 90 billion transistors – offer “a significant upgrade in core performance” according to AMD: about 14% more instructions per clock (IPC), based on a geomean of 33 server workloads. Security-focused enhancements include expanded AMD Infinity Guard and a doubling of encryption keys. Genoa also introduces support for CXL 1.1 for memory expansion. At a launch event held today in San Francisco, AMD announced the general availability of its newest Epyc CPUs with up to 96 TSMC 5nm Zen 4 cores, 12 channels of DDR5 memory and up to 160 lanes of PCIe Gen5. Introducing the Core i5 750.Since 1987 - Covering the Fastest Computers in the World and the People Who Run ThemĪMD’s fourth-generation Epyc processor line has arrived, starting with the “general-purpose” architecture, called “Genoa,” the successor to third-gen Epyc Milan, which debuted in March of last year. Without further ado, let’s take a better look at the CPU on offer today. The C2D and Pentium processors still make up a significant amount of the market but the Nehalem micro-architecture is expected to take over gradually.Īs a rule of thumb, the i7 series is high-end intended for hardcore enthusiasts, Core i5 is mid ranged with the Core i3’s (yet to be released) aimed at entry level customers. The Core i5’s aim is to offer what the i7’s couldn’t – an affordable mid-range CPU. After all, the LGA1366 socket requires not only the processor but also an X58 motherboard and triple channel DDR3 memory. The processors have had a mixed reception and it is fair to say that although the new series has been impressive performance wise, the pricing was and still is too much for many users. The introduction of the Core i7 range of processors late last year was the beginning of the Nehalem family.
