Since early 2011 the hallmark of HP Pavilion dm1z series has been the use of AMD FUSION technology: an “accelerated processing unit” (APU) which combines a dual-core CPU with a Radeon graphics processing unit (GPU) on a single processor die. This allows HP to squeeze more computational power into the same small space as a netbook but deliver notebook-like performance. Another way of putting it is that the E-series APUs inside the dm1 blow away any other netbook equipped with an Intel Atom processor.
Performance and Benchmarks
The new E-450 dual-core processor runs at a clock speed of 1.65GHz and the Radeon HD 6320 graphics cores run at 508MHz. This is a very minor speed boost over the 1.6GHz E-350 APU used in the old dm1 models. That said, general productivity tasks and editing video are “snappier” with the dm1-4010us compared to the model from earlier this year. While one can argue the new APU deserves some of the credit for performance, the faster hard drive in this notebook is also largely responsible.
The 320GB, 7200 rpm hard drive is slightly faster than the hard drive in the previous generation dm1. This hard drive is fast enough to quickly load most basic applications like Microsoft Office or Adobe Photoshop but it simply doesn’t offer the extreme bursts of speed that you get from a SSD or a hybrid hard drive like the Seagate Momentus XT. That said, adding a faster storage drive in this machine would unnecessarily raise the price.
We don’t usually test netbooks with the 3DMark 11 benchmark, but AMD is quick to point out that the E-series APUs are capable of DirectX 11 gaming, so we ran the performance test in 3DMark 11 just to see the results. As the numbers show below, the dm1-4010us puts up a modest fight with DX11 games — certainly better than Intel Atom netbooks which can’t handle DX11 at all — but you’re better off with a system like the Alienware M11x R3 if you are looking for an ultraportable “gaming notebook.”
