It was introduced in June 1998. Bitcoin 28nm cmos also support multi-socket systems with 2, 4, or 8 sockets.
In the second generation, Xeon Phi evolved into a main processor more similar to the Xeon. Xeon, the design point of the Xeon Phi emphasizes more cores with higher memory bandwidth. 450 MHz Pentium II Xeon with 512 KByte L2 cache: The cartridge cover has been removed. The L2 cache was implemented with custom 512 kB SRAMs developed by Intel. The number of SRAMs depended on the amount of cache. A 512 kB configuration required one SRAM, a 1 MB configuration: two SRAMs, and a 2 MB configuration: four SRAMs on both sides of the PCB.
Each SRAM was a 12. That came in two variants: with 1 MB or 2 MB of L2 cache. Its bus speed was fixed at 100 MHz, though in practice the cache was able to offset this. This improved performance slightly, but not enough to lift it out of third place. 80528 product code with Willamette.
It supported Intel’s new Hyper-Threading technology and had a 512 kB L2 cache. L3 cache of 1 MB or 2 MB. 1 MB L2 cache was released in 2004. The Xeon was noticeably slower than AMD’s Opteron, although it could be faster in situations where Hyper-Threading came into play. 2005, with 2 MB L2 cache and the ability to have its clock speed reduced during low processor demand. Both of these Prescott-derived Xeons have the product code 80546. 64-bit Xeon MPs were introduced in April 2005.
