Doesn't make any sense to release another 995X chip. The 990X was already launched silently and is pretty much the same silicon quality as 980X.
Intel is preparing its next high-end/enthusiast desktop platform for release in Q4 2011. That platform will be driven by a new socket, the LGA2011, and the new Intel X79 Express chipset. Before that, Intel will give its 2-year old current enthusiast platform, the LGA1366 and X58 Express, a fitting farewell with a new high-end processor model, the Core i7-995X Extreme Edition. The i7-995X is a six-core processor based on the 32 nm "Gulftown" silicon. It features a default clock speed of 3.60 GHz (27 x 133 MHz), 3.86 GHz max Turbo, though the BClk multiplier is unlocked to help with overclocking.
The six x86-64 cores are aided by Intel HyperThreading technology to give the OS a total of 12 logical CPUs (threads) to deal with. The processor features a triple-channel (192-bit wide) DDR3 memory controller, and connects to the X58 chipset over a 6.4 GT/s QuickPath Interconnect link. Intel will launch its new chip some time in Q3 2011, i7-995X is expected to be priced at $999 (in 1000-unit tray quantities), displacing the current SKU at this price, the Core i7-990X Extreme Edition. For now, a lucky few (read: "industry partners") have access to engineering samples.
