Fresh from the launch of its second generation six-core workstation / server CPUs, the uber-fast and Xeon 5600-series, Intel is now ready to unveil its first ever eight-core CPU. Meet the Xeon X7500-series, codename Nehalem EX - we put it through its paces in a 64-thread test system.

AMD has launched its fastest desktop CPU ever, the Phenom II X4 965 Black Edition. With an improved manufacturing process making it more tolerant of high voltages, is this the most overclockable Phenom ever?

If you thought Core i7 was fast, prepare to be shocked all over again - you can run two Nehalem EP Xeon W5580s together in one motherboard. We take a look at Intel's latest workstation/server CPU which is up to 93 per cent faster than previous Core 2 architecture Xeons.
