[中央處理器] Intel® Xeon® Processor E3-1231 v3

想問一下, 有無C.hing 知道同E1230V3 除高0.1GHz 外, 仲有乜分別 ???

Not exactly
TDP is not power consumption, it's just the maximum amount of heat the cooling system should dissipate

咁D熱係邊度黎丫...

熱由心出. 你想知道實際用電量, 你應該用叫KILLERWATT的量電器得知.

另外, V3同V2的分別主要有三

1.散熱好

2.較上代省電,相同效率.

3.無內顯

On-die VRM

The bad news is that building the FIVR on die may hurt CPU temps and overclocking at higher clock speeds. According to leaked (but trustworthy) spec sheets, the upcoming HD 4770K series holds the line on base and turbo clock speeds compared to the 3770K, but increases TDP to 84W, up from 77W. That increase is likely driven by incorporating the FIVR. That doesn't mean the system's power consumption has changed, but a component that used to exist in a separate domain is now being cooled by the CPU heatsink+fan and sits within the same socket.

Here, another test showing the relation between rated TDP and platform power consumption
http://techreport.com/review/248 ... ocessors-reviewed/7
By spec, the 4770K has a 7W higher power ceiling than the 3770K. In this test, the difference in total system power consumption boils down to just 1-2W.

With IGP disabled, Haswell has nearly identical peak power consumption as Ivybridge (remember they are using two different motherboards)
But idle power and task energy test suggest a fair improvement in power efficiency

咁我都知, 但普遍黎講, 網上評測多數都係指 v3 相對比較耗電, 而且仲熱好多
