Power-draw credentials

We've skirted around the power-efficiency angle thus far, and it's important to discuss because it's what makes the 2500S and 2500T chips special.

Sat twiddling their silicon thumbs at the Windows desktop screen, there's not a whole lot to separate them. The minimum power-draw is predicated more by the motherboard than the chip.

Beat up on the CPU cores and the 2500T (45W) and 2500S (65W) show clear power-draw advantages over the full-fat (95W) models, though the differences may not be as large as you would expect by looking at on-paper specs.

Fire up a taxing game and the power-draw differences actually diminish. Looking at our numbers, it's difficult to make a case for lower-power chips when the full-fat 2500K draws an additional six watts during gaming.
