As mentioned earlier, our review unit came with AMD’s E-450 processor. A minor update to the proceeding E-350, it is a dual-core part with a clock speed of 1.65 GHz, a mere 50 MHz increase. More relevant is the Radeon IGP built in to the processor, which is now clocked at 600 MHz rather than 492 MHz. The processor was backed up by 4GB of RAM, so there was plenty of memory available.
While any increase in clock speed is appreciated, a mere 50 MHz bump in a part with low per-clock performance is nothing to be excited about. In SiSoft Sandra the E-450 returned a combined processor arithmetic score of 8.53 GOPS, while 7-Zip showed a combined score of 2433. These results are significantly lower than those provided by an Intel Core i5. Even the low-voltage Core i5 in the Acer Aspire S3 more than triples the E-450’s SiSoft Sandra results and doubled the 7-zip results. While some might debate that the HP dm1z is too large to be a true netbook, they certainly can’t debate it is too powerful to be a true netbook.

Or maybe they can – if they approach it from the perspective of graphics. The HP dm1z returned a PCMark 7 score of 1083, which is still low, but reduces the margin of the laptop’s defeat. Running 3DMark 06 resulted in a score of 2710, which is lower than Intel’s HD 3000 IGP, but much better than that provided by Intel Atom netbooks, which are still saddled with the ancient GMA3150.
That graphics solution usually manages a score of just 150 in 3DMark 06. No, I didn’t forget a zero. While an Atom netbook will struggle to play some games sold ten years ago, AMD’s E-450 can run many modern 3D games at playable framerates so long as you keep their detail set to low.
These results, poor though they may be compared to Intel Core powered laptops, represent the best you can expect from a modern netbook processor. This is the price you pay in exchange for over eight hours of battery life in a laptop that costs less than an Apple iPad.
