Report an Error Intel Xeon Phi 3120A 57 Cores 228 Threads 300 W TDP 1100 MHz Frequency N/A Boost Knights Corner Codename PCIe x16 Socket
Front
PCIe x16 The Intel Xeon Phi 3120A is a server/workstation processor with 57 cores, launched in June 2013. It is part of the Xeon Phi lineup, using the Knights Corner architecture with PCIe x16. Intel Hyper-Threading technology is available and effectly doubles the core-count of the P-Cores, to a total of 228 threads. Xeon Phi 3120A has 512 KB of L2 cache per core and operates at 1100 MHz. Intel is building the Xeon Phi 3120A on a 22 nm production process using 5,000 million transistors. The multiplier is locked on Xeon Phi 3120A, which limits its overclocking capabilities. With a TDP of 300 W, the Xeon Phi 3120A is extremely power hungry, which means you need top-notch cooling. Intel's processor supports DDR3 and DDR4 memory. ECC memory is supported, too, which is an important capability for mission-critical systems, to avoid data corruption. This processor lacks integrated graphics, you might need a graphics card. Hardware virtualization is available on the Xeon Phi 3120A, which greatly improves virtual machine performance. Additionally, IOMMU virtualization (PCI passthrough) is supported, so that guest virtual machines may directly use host hardware. Programs using Advanced Vector Extensions (AVX) will run on this processor, boosting performance for calculation-heavy applications. Besides AVX, Intel is including the newer AVX2 standard, too, but not AVX-512. Physical

Notes
| On November 15, 2011, Intel showed an early silicon version of a Knights Corner processor. On June 5, 2012, Intel released open source software and documentation regarding Knights Corner. In June 2012, Cray announced it would be offering 22nm 'Knight's Corner' chips (branded as 'Xeon Phi') as a co-processor in its 'Cascade' systems. |
