Intel launches Third-gen Xeon knowledge centre processors

by akoloy


Intel’s third-generation Xeon “Ice Lake-SP” knowledge centre processors have arrived to problem AMD’s “Milan” Epyc processors.

Codenamed Ice Lake-SP, the brand new processors use Intel’s 10nm+ transistors and the Sunny Cove core structure that debuted in 2019. According to Intel, Ice Lake-SP boasts 1.7x AI inference efficiency, 1.62 occasions community efficiency, and 1.5 occasions enchancment in latency-sensitive cloud functions.

Overall, the corporate stated clients can count on a 2.65 occasions common efficiency enhance in comparison with a five-year-old system.

Additionally, Intel claimed that Ice Lake-SP is quicker than AMD’s just lately introduced Milan processors in sure workloads.

Its press slides confirmed that with built-in AI acceleration, Ice Lake-SP is as much as 25 occasions sooner in picture recognition and total 1.5 occasions sooner in 20 ML workloads. Similarly, Ice Lake-SP was proven to be sooner than the Nvidia A100 GPU in these functions as nicely.

The processor’s numerous architectural enhancements quantity to roughly a 20 per cent IPC uplift. Ice Lake-SP’s Sunny Cove core brings a better capability department predictor and considerably larger execution assets. Moreover, it will increase the interpretation lookaside buffer (TLB) web page assist to 1024, 64 occasions that of Cascade Lake, to cut back reminiscence entry latency.

Other enhancements embody bigger cache sizes, new directions for AI, compression, decompression and SIMD.

Every processor helps 6TB of DDR4 ECC reminiscence, 2.6 occasions greater than the earlier Xeon technology. Memory will be put in in as much as eight-channel configurations. Ice Lake-SP additionally helps Intel Optane persistent reminiscence and options as much as 64 PCIe 4 lanes per socket.

Ice Lake-SP additionally comes with safety safeguards, together with reminiscence encryption, firmware safety, and Intel’s software program guard extension suite. Furthermore, it options improved cryptography acceleration to assist with duties akin to monetary transactions.

There are a whopping 57 SKUs to select from. They’re divided into 10 segments, every optimized for a particular use case or cooling demand. The vary between 10 to 40 cores and 105W to 250W TDP and multi-socket configuration ranges from single to eight sockets.
