The Intel Core 2 Extreme X7900 was a mobile processor with 2 cores, launched in August 2007, at an MSRP of $851. It is part of the Core 2 Extreme lineup, using the Merom XE architecture with Socket P. Core 2 Extreme X7900 has 4 MB of L2 cache and operates at 2.8 GHz. Intel is building the Core 2 Extreme X7900 on a 65 nm production process using 291 million transistors. You may freely adjust the unlocked multiplier on Core 2 Extreme X7900, which simplifies overclocking greatly, as you can easily dial in any overclocking frequency.
With a TDP of 44 W, the Core 2 Extreme X7900 consumes typical power levels for a modern PC. Intel's processor supports DDR2 memory with a dual-channel interface. Actual memory technology support depends on the chosen motherboard, because the memory controller is located on the motherboard (not in the processor). For communication with other components in the machine, Core 2 Extreme X7900 uses a PCI-Express N/A connection.
The SSE4 instruction set is not supported, which can cause problems with modern games, as they require that capability. Hardware virtualization is available on the Core 2 Extreme X7900, which greatly improves virtual machine performance.
