Elmer - RE: "what you just described is EXACTLY what double pumped means" Thanks for the clear up. Ace's has ANOTHER update about Willy's ALU. Apparently now a different Intel rep is saying it IS 3GHz! aceshardware.com and aceshardware.com Johan says this is Intel's official explanation - "The ALU is running at 3Ghz. The clock for the 3Ghz is generated in reference (strobe) to the 1.5 Ghz base clock. Means, if the base clock would be 1.4Ghz, the ALU would run at 2.8Ghz. Effectively the transistors have to switch at a rate required to achieve 3 Ghz (1/3000.000.000 s). This is also called double pumping which could be described as well: The processor could finish a calculation in the first half of the base clock and pass on the data for further actions in the second half of the clock (again base clock). The conclusion is that the ALU latency is 0.5 clocks (in reference to the base clock). To achieve a 0.5 clock latency in both ALUs, the ALUs have to run at the double of the base clock. In this case, it was 3 Ghz." "Cringe" And you wonder why people are sometimes hostile towards you...
