The Intel Core 2 Extreme X6800 was a desktop processor with 2 cores, launched in July 2006, at an MSRP of $999. It is part of the Core 2 Extreme lineup, using the Conroe XE architecture with Socket 775. Core 2 Extreme X6800 has 4 MB of L2 cache and operates at 2.933 GHz. Intel is building the Core 2 Extreme X6800 on a 65 nm production process using 291 million transistors. The multiplier is locked on Core 2 Extreme X6800, which limits its overclocking capabilities. With a TDP of 75 W, the Core 2 Extreme X6800 consumes typical power levels for a modern PC. Intel's processor supports DDR1, DDR2 and DDR3 memory with a dual-channel interface. For communication with other components in the computer, Core 2 Extreme X6800 uses a PCI-Express Gen 2 connection. Although the processor doesn't come with integrated graphics, certain motherboards with compatible chipsets can provide this capability. The SSE4 instruction set is not supported, which can cause problems with modern games, as they require that capability.
