SoC Power降了12W，和预估的差不多
package power不变估计是core power上去了，吃掉了SoC部分节约的功耗，而package power受制于散热规模上不去
搜了一下hardocp做过2990WX配合银箭TR4的评测，可惜这人跳槽outel之后把hardocp网站关掉了，现在只能看google cache，看不到图：
The delta between the Thermalright and the Cooler Master on this run is a minimal ~50MHz. Even with our 2990WX it can still edge out a tiny lead, which I find somewhat impressive. Of course the standout here is our XSPC cooler which allows our 2990WX to run a full ~666MHz faster than the Silver Arrow TR4...devilish. If you look however, both our air cooler systems are running clocks lower than they were with Precision Boost 2. Certainly that is not good. PBO is penalizing us on air compared to PB2.
Keep in mind, that our 2990WX has a specified TDP of 250 watts. The Silver Arrow TR4 run shows to be using 283 watts package power. The Wraith Ripper system package power is 42 watts lower. I think this spread between the two air coolers does not seem quite "correct." Surely as the 2990WX get hotter, its power usage becomes exponential and certainly does not ramp linearly, but it still seemed like a big bump to me. If you look, the Cooler Master cooler is actually below TDP. Certainly the water cooled 2990WX is rolling through the power. While 442 watts might seem excessive, we have seen package power above 650 watts doing hand overclocking here recently. No matter how you look it, PBO is an issue for our air coolers in terms of clocks and power.
水冷能比银箭快666MHz，package power能压到442W，银箭能压制283W package power
你这里只有210W的话，可能是机箱温度比hardocp的测试环境温度要高
先试试银箭上挂满3风扇吧，高马甲条的话竖直机箱没法固定风扇，我的做法是主板平放，用胶带把TY-143扇子固定住 |
