The AMD Opteron 146 was a server/workstation processor with 1 core, launched in August 2005, at an MSRP of $218. It is part of the Opteron lineup, using the Venus (D4) architecture with Socket 940. Opteron 146 has 1 MB of L2 cache and operates at 2000 MHz. AMD is making the Opteron 146 on a 90 nm production node using 114 million transistors. The multiplier is locked on Opteron 146, which limits its overclocking potential.
With a TDP of 67 W, the Opteron 146 consumes typical power levels for a modern PC. AMD's processor supports DDR1 memory with a dual-channel interface. The highest officially supported memory speed is 400 MT/s, but with overclocking (and the right memory modules) you can go even higher. Although neither the processor nor its chipsets support integrated graphics, certain motherboards include dedicated graphics chipset that can provide some basic display output functionality.
The SSE4 instruction set is not supported, which can cause problems with modern games, as they require that capability.
