[Tom's] Intel ATOM mini-review

post #1 of 7
Thread Starter 
Wanna see how Intel's latest low cost CPU ATOM @1.6GHz HyperThreading runs versus the proven Pentium 2160 @1.6GHz?

Answer here: Tom's article

Quote:
To measure the performance of the Atom, pending more complete testing, we used an entry-level processor, Intel’s Pentium E2160. We reduced the E2160’s speed from 1.80 GHz to 1.60 GHz (the same as the Atom) and tested it on a motherboard similar to that provided with the Atom: i945G chipset, ICH7 and one 1 GB of DDR2 memory.

instead of downclocking why didn't they just use the e2140

You know, the Atom is actually less powerful than their previous model, the Celeron 220.

For the ones that are not up to date with the Intel ATOM CPU, it's designed to fit a power envelope of 3W. It is also designed to be cheap, thus the retail price will probably be below 30$ and still give Intel a nice profit margin.

The ATOM isn't build for anything more than a ultra low end computer, and I would venture to say that its performance can't be that far of a 1GHz Pentium III. I would be curious tho how would it fare against the Celeron ULV 900MHz that powers the EEE PC, because after all this is where it's gonna find its niche.

Celeron 900Mhz did better then Atom 1.33GHz.

We measured a power consumption difference of 19W between our two test platforms. Note however that the frequencies did not seem to change as they would with true mobile power reduction circuitry and that the motherboard’s i945G chipset has a GMA 950 clocked at 400 MHz. The version used in notebook PCs will use a slower GMA which should reduce the power consumption of the platform.

The complete Atom platform (i945 motherboard + 1 GB DDR2-667 + Raptor 74 GB HDD) consumed 59W, while the Pentium E-based platform consumed 78W.
So you really need that Intel board to get the super low power usage.
