Intel’s Mobile Core i5 And Core i3: Arrandale Is For The Rest Of Us

Our threaded Photoshop benchmark demonstrates an advantage in favor of Intel's Hyper-Threading technology, as Asus' K42F beats out the competing HP Penryn-based machine.

The difference between a dual-core processor and a dual-core processor with Hyper-Threading is staggering in AVG 9. We’ve seen this same behavior in past performance evaluations, where the anti-virus suite uses very little resources, but rewards the shift to more logical cores with a halved completion time.

We know that this one is threaded, so the massive speed-up in going with the Arrandale platform is attributable mostly to Hyper-Threading (though we also know a Turbo-equipped CPU under its TDP will still add a 133 MHz bin of acceleration, even when both cores are being utilized).

Considering that WinRAR is threaded, it’s interesting to see Hyper-Threading having little effect on this test’s overall standing. For the most part, both of these mobile platforms are even.

In a big contrast to WinRAR, 7-Zip shows a massive gain in favor of Hyper-Threading. The speed (KB/s) and rating (MIPS) components of our compression routine really accelerate Intel's Arrandale processor.
