Atom Z2760挣扎运行win8 desktop

spring62

还请开word打字能把CPU吃到50%的伟大的ARM来说话
而且这还是个阉割的win以及word

atom跑win8的桌面模式是有点强人所难了，体验肯定不会好

Atom玩桌面模式在挣扎，ARM微软干脆连它玩桌面模式的机会都没有

楼主的帖子只能让我用一句话来形容：

Surface的测评
In Word, it’s relatively easy to pull 30% CPU utilization when typing quickly. Anand saw up to 40% on Surface, and I managed to get CPU utilization all the way up to 55% when pressing random keys as quickly as possible. Compare this to Notepad, which usually hovers in the 5-10% CPU utilization range, and it’s clear to see how heavy a load Office puts on the system. Even with the high CPU utilization though, I never saw any lag in the characters appearing, so it’s mostly an interesting point to note and not an issue with the typing experience.

To really push the system, I loaded up some of the Excel files I work with at my real life job as an automotive technology researcher. These are raw and mostly unprocessed dynamometer data test files, with roughly 3 million data cells each (give or take.) The largest had just under 4 million data cells and was 39MB in size, smallest about 1.8 million and 19MB in size. A couple of graphs and some equations. Together, the four files totaled 112MB. I decided to open all four at once - it took about a minute and a half, with a max CPU load of 72%. It was crazy, but once everything was loaded, performance was actually decent. I wouldn’t want to necessarily work on the files for extended periods with a system like this - the screen is too small, and the couple of bits of lag would drive me nuts (plus, without Matlab, it’s a bit pointless) but for quick graphing of basic data, it works significantly better than expected.

记事本都能跑到10%的性能，这是20年前的CPU吧。Excel能跑到72%，T神不是说WinRT不支持4核吗？

其实还是比4核的RT好的。
桌面软件很多是无下限的，很多PC用户还抱着这种习惯用平板，会死得很惨，例如360，例如QVOD还后台悄悄传，还顺便自启动点PPS之类，挂个迅雷吃掉几百MB内存之类的。

但是ATOM用Metro应用很顺了，不比RT差。
装Office2013，相对RT上的缩水版，至少不会段落中插入东西打字延迟。

ATOM会轻易被无下限的桌面软件拖垮，但会用的人，会远比RT用得自在。

笑死人了，都是单线程程序那Surface打字怎么会有50%占用率？

打字的时候，t3是单核占有率50%还是四核的总占有率是 50%？
给出原始链接或文字，才能进一步讨论。

自己看9楼去

PS:这是单线程占用50%时会出现的状况？？？

另外每次YY软件都是单线程前先想想半年后4T A15vs 2T 22nm atom时怎么收场

Windows下CPU占用率是整个一起算的，i7单核满载CPU占用率是12%

我手机上网不想看视频。

按照t3总占有率50%计算，tegra4的四核A15@1.6Ghz占有率会在30%以内，打字表现 ...

打字30%叫可以？我用586跑95的时候，用Word打字也没出现过30%的CPU占用率。

不用什么原始链接，我亲自试过，头脑发热，苏宁首发第二天就买了。
记事本里面连续打字，10%左右波动。
Office里面连续输入40-50%波动。
这个是总的CPU占用率，至于4个核看起来，反正都差不多。
其实CPU占用普通用户也没空关心，关键是：
如果是在段落中插入字，而不是在文章末尾输入。
可能会造成输入延迟。
不是因为这个，也没空去关心CPU占用，毕竟RT有桌面却没杀软件可用，基本等于单任务，不卡就行。
