Icon17 Intel Atom 230 (1.6Ghz) 4W TDP does SuperPi 1M in 92.766 Seconds

FudZilla got a chance to test Intel's low power CPU dubbed the "Atom". Running at 1.6Ghz they ran a few benchmarks on the CPU which they called slow overall.


The benchmarks include MP3 Lame encoding, Sisoft Sandra and the enthusiast all time favourite: SuperPi !

Quote:
Sandra tells us that the 1.6GHz Atom is about two times slower than the single core Celeron 420 at the same clock speed, at least in the FPU test. It was funny to notice that the 3GHz Core 2 Duo E8400 scores ten times better than the Atom 230.

As long as you don't use any multi-media applications, the system runs fine. So the most common use will be for POS systems or surfing stations. But if you think you want to do some multi-media stuff, just forget it, it's too slow.
Not very promising, but it's a low power unit, raw single threaded application performance can be gauged by running SuperPi 1M:



If these results can be trusted, the Intel Atom 1.6Ghz scores 92.766 seconds at 1M.

If we take a look at the HWbot.org database and check for results between 92 & 93 seconds we get the following list of CPUs:


The Atom 230 (1.6Ghz) is as fast/slow in SuperPi as:
- Pentium 4 Wilmetta @ 2125Mhz
- Pentium 3 @ 1517Mhz
- Athlon Tbird @ 1616Mhz
- Pentium M 745 @ 1804Mhz
- Pentium 4 Nortwood @ 2.4Ghz
- Duron 600@1069Mhz

The SuperPi 32M result is even worse, as it's not even able to match Pentium 3 1Ghz CPU ( http://hwbot.org/listResults.do?cpuM...true&limit=100 )

Do note that SuperPi performance is also decided by memory bandwidth, so take these results with a grain of salt when comparing raw CPU performance.

It does give a clear message though that this CPU is not really going to be that hot for building yourself a low power system; if you buy an entry level 45nm Core 2 Duo you won't be using up that much power and you'll get plenty of performance. Even if the Atom 1.6Ghz uses less than the average power-saving light-bulb, it's not really enthusiast material;

Superpi 1M has a future after all

A P3 1Ghz has TDP rating of 26W
A Pentium M 2.16Ghz 27W
A Pentium M 778 1.6Ghz... 10W rating

... and let us not forget:

A Core Solo U1400 1.2Ghz 5W which does SuperPi 1M in 48.97 seconds http://hwbot.org/result.do?resultId=603809

but the real advantage of the Intel Atom is neither power usage or performance. Physical size is what it is all about:
