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 ...

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 faste ...

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/serv ...

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