7400/7410 350–550 MHz, uses AltiVec, a SIMD extension of the original PPC specs 7440/7450 micro-architecture family up to 1.5 GHz and 256 kB on-chip L2 cache and improved Altivec 7447/7457 micro-architecture family up to 1.83 GHz with 512 kB on-chip L2 cache
750CXe (codename Anaconda), introduced in 2001, is a minor revision of 750CX to increase its clock speed to 700 MHz and memory bus from 100 MHz to 133 MHz. The 750CXe also features improved floating-point performance over the 750CX. [5] Several iBook models and the last G3-based iMac have this processor.
Power 760 (9109-RMD) (1~4 12-core POWER7+ DCMs) [14] 2014 POWER8-based IBM Power Systems E870 can be configured with up to 80 processor cores and 8 TB of memory.
The first devices used standard processors, but later consoles used bespoke processors with special features, primarily developed by or in cooperation with IBM for the explicit purpose of being in a game console. In this regard, these computers can be considered "embedded".
IBM states that it is two to three times as fast as its predecessor, the POWER7. It was first built on a 22 nanometer process in 2014. [4] [5] [6] In December 2012, IBM began submitting patches to the 3.8 version of the Linux kernel, to support new POWER8 features including the VSX-2 instructions. [7]
IBM POWER is a reduced instruction set computer (RISC) instruction set architecture (ISA) developed by IBM.The name is an acronym for Performance Optimization With Enhanced RISC.
Watson employs a cluster of ninety IBM Power 750 servers, each of which uses a 3.5 GHz POWER7 eight-core processor, with four threads per core. In total, the system uses 2,880 POWER7 processor threads and 16 terabytes of RAM. [14] According to John Rennie, Watson can process 500 gigabytes (the equivalent of a million books) per second. [15]
