It is part of the Core 2 Extreme lineup, using the Merom XE architecture with Socket P. Core 2 Extreme X7800 has 4 MB of L2 cache and operates at 2.6 GHz. Intel is making the Core 2 Extreme X7800 on a 65 nm production node using 291 million transistors. You may freely adjust the unlocked multiplier on Core 2 Extreme X7800, which simplifies overclocking greatly, as you can easily dial in any overclocking frequency.
With a TDP of 44 W, the Core 2 Extreme X7800 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 system, Core 2 Extreme X7800 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 X7800, which greatly improves virtual machine performance.
