Did you get that from the Inquirer, Andreas? I could swear Magee had a story up there with the link you posted, but it seems to have disappeared. Oops, here it is: theinquirer.net , I got confused by the melodramatic headline. I'm sure Mike will ask Craig about his horse Pentium if the opportunity arises. I wonder if Joe is anybody we know.

The most important data points (for the 1.13 GHz, 512KB L2 cache version): Voltage: 1.45V T_Case: 69°C Max power consumption: 27.9W 28W? That's quite disappointing. Although this is a maximum number (not TDP), it's much more than I expected -- especially since the CPU is running at 1.45V (instead of 1.75V). I.e. a mobile Athlon 4 is very competitive with Tualatin. The 1 GHz version has a maximum power consumption of around 30W, that's less than 10% more. Glass half empty or half full argument: How much difference does the bigger cache (512 KB vs. 256 KB) make? You say A4 is around 27.9 watts. What's it's max power, for an apples to apples comparison. As you point out, the intel spec. calls out a max Icc. Power goes up as with frequency. 1.13 > 1.0 (Tualatin vs. A4). This is an early 0.13 part. Further iterations may take the power down at the same voltage and clock speed? I'll read the spec. more later. From the spec.: 512 KB Advanced Transfer Cache (on-die, full speed ...with Error Correcting Code (ECC). Will Intel use the 512K cache version for servers? I certainly would. Why not? Tony

Re: "The 1 GHz version has a maximum power consumption of around 30W, that's less than 10% more." But that's with the mobile AThWiper running at 13% LESS Speed !

Andreas: 28W? That's quite disappointing. (...) mobile Athlon 4 is very competitive with Tualatin. The 1 GHz version has a maximum power consumption of around 30W, that's less than 10% more. Well, there is some "moving" of power consumption here. Because it has 512kB of on-die L2 cache, the Tualatin will consume relatively more power. However, there will be far fewer accesses to main memory, which not only speeds up the system, it also significantly reduces overall power consumption. -fyo
