IBM z196 CPU Fastest Microprocessor

IBM gives us more details on its 5.2 GHz IBM z196 microprocessor, which is the fastest ever. To be used on IBM mainframe Z series, the z196 is a CISC chip with 1.4 billion transistors on 512 mm square chips manufactured on 45-nm SOI technology PD, 64 KB of level-1 cache of instructions, a 128-Kbyte L1 data cache, L2 cache of 1.5MB private by heart, and a pair of co-processors used for cryptographic operations.

The IBM z196 also gets 19.5MB SRAM L1 cache private, 144 MB of L2 cache and 576 MB SRAM private cache L3 eDRAM. It will be delivered in September and will cost hundreds of thousands of dollars, if not more than one million.
