主题：【注意】90nm的AMD Athlon发热知多少？ -- Highway

AMD已经于日前推出了90nm的Athlon CPU。虽然开始起跳的速度并不快，但大家关心的是90nm的工艺能否把发热降下来一下，为今后进一步提升频率铺平道路。

据玩家们的初期测试，新的CPU表现良好。比同频率的130nm Athlon有不小的下降，空闲时的CPU温度以及全负荷状态下的温度都比以前下降了6-7度。比起Intel 90nm Pentium 4(3.4GHz)那更是低了很多。非常令人鼓舞。

空闲时，130nm Athlon 64 温度为49度，10分钟全负荷运转后为61度；而90nm Athlon 64分别为41度，55度。

测试系统大致是这样的：

Let me give you the test setup briefly. We compared power consumption by measuring power usage for our entire testbed system, sans monitor, at the wall outlet.

The testbed system included an Asus A8V Deluxe motherboard, 1GB of Corsair XMS 3200XL DDR400 memory, an NVIDIA GeForce 6800 GT graphics card, an Asus DVD-ROM drive, a Maxtor MaxLine III 250GB SATA hard drive, and an OCZ PowerStream 470W power supply. (The 130nm chip we used was actually an Athlon 64 3800+ underclocked to 2.2GHz, for what it's worth.) We also tested power consumption on a similarly-configured Pentium 4 system based on an Abit AA8 DuraMax motherboard with 1GB of OCZ DDR2 533MHz memory and the PCI-E version of the GeForce 6800 GT (all other components were the same as the Athlon 64 rig). The Pentium 4 was a Prescott 90nm core running at 3.4GHz. Update: Cool'n'Quiet was not enabled on the Socket 939 motherboard.
