This fast?!

这两年无论是AMD还是Intel，处理器性能的提升幅度都小得可怜，但如果把眼光放长远一些，历史的进步还是相当猛的，可能会超出很多人的想象。
比如一边是今年的Celeron J1850，Bay Trail-D入门级桌面平台，22nm工艺，四核心，主频2.0GHz，热设计功耗10W；另一边是2008年初的Core 2 Duo E8200，扣肉时代的高端桌面产品，45nm工艺，双核心，主频2.66GHz，热设计功耗65W。
将它们俩放在一起，孰强孰弱呢？
作为基准性能测试软件开发商，PassMark Software的官方网站上还有一系列的处理器、显卡、硬盘性能数据库。通过查询可知，Celeron J1850的平均得分为1814，Core 2 Duo E8200则是平均1845。
这意味着什么？五年多过去了，你现在只需要当初不到六分之一的功耗，就可以得到几乎同样的性能，如今的入门级产品已经媲美当年的高端型号了！
此外，Ivy Bridge家族的双核心Celeron G530T 2.0GHz/35W平均得分为1604，换了“Atom芯”的新赛扬都要比它强13％呢。
这一系列还有更高端的Pentium J2850/J2900 2.41GHz，得分超过2000应该不成问题。

时代的进步

呢邊10W 個邊就200W

比如一边是今年的Celeron J1850，Bay Trail-D入门级桌 ...

AMD A6-5200 APU (25W TDP, 4C, 2.0GHz) 2,446
AMD A4-5000 APU (15W TDP, 4C, 1.5GHz) 1,912
AMD A6-1450 APU (8W TDP, 4C, 1.4/1.0GHz) 1,644
AMD E1-2500 APU (15W TDP, 2C, 1.4GHz) 837

不過就算係數字快過C2D, single-thread performance (低階CPU比較重要的metric) 都係差1倍,
PassMark基本上係perfect scaling.

Not exactly, if the quad core score is counted by 1.99GHz,
then with single core + turbo boost, the difference should be narrower.
And for J2900, 10W TDP but 2.4GHz quad core, it should be much faster.

Not really for J1850, as they were taking G530T in the test,
G530 itself can reach 22XX in passmark, but still it maybe overtaken by J2900 later....

For similar mark with dual-core E8400, the single-thread performance difference is 100%, turbo boost by 20% will narrow the difference to about 67% times faster (2/1.2 = 1.67).

You mean J2900 vs A6-5200?
AMD deliberately disables turbo-core for high-end Jaguar cores, so the real difference is not that large.

And for Pentium J2900, the expected mark is about 2218

Recalling the Celeron G530 I got in early 2012, it took like 22XX marks in passmark,
and is now overcome in the multithread score by this 10W TDP monster.........time to build the new router/nas/server with ATOM

In fact, a dual-core Bay-Trail or dual-core Jaguar is more than enough for router / nas / low-end server.

want to replace it for my main computer, turn it to 24 hrs on machine

I doubt that it would suffice daily use at this time.
You'd better stick with G840 for a better performance, assembling yet another Bay Trail server would be more appealing.

睇下佢d版要幾多錢可以諗下換換佢
