Intel is planning on a newer flagship desktop CPU to lead the Core i7 Extreme Edition pack: the Core i7 975 Extreme Edition (XE). The model surfaced at an XtremeSystems forum thread where overclockers FUGGER and Mikeguava took a shot at the 3DMark05 world record of 45,474 3DMarks, set by AMD at its presentation of the Phenom II X4 processor running at speeds of around 6.30 GHz. The overclockers used a bench consisting of the new Core i7 975 XE, Gigabyte GA-EX58 Extreme motherboard, two Radeon HD 4870 X2 accelerators in a CrossFireX setup, powered by a PC Power & Cooling Silencer 750W PSU. The CPU was cooled by a custom-made copper cooling pot. At a clock speed of 5,239 MHz and the graphics cards running at reference speeds, the bench cracked the world record to reach 47,026.

During the course of this feat however, we get to know more about the Core i7 975 XE. The new premium offering by Intel comes with a clock speed of 3.33 GHz. It achieves this frequency using a bus multiplier of 25X. Intel built this chip on the new D0 revision of the Bloomfield core, on which the company also plans to release fresh batches of the Core i7 920. Apart from the unlocked bus multiplier and the broader QuickPath Interconnect bandwidth of 6.4 GT/s, other features remain standard: 4 processing cores supporting 8 threads with HyperThreading enabled, 256 KB of L2 cache per core, 8 MB of shared L3 cache, and a triple-channel DDR3 memory interface.
