Performance in Applications
To test the performance during data archiving we used popular WinRAR and 7-zip archiving utilities.
As we can see, even faster DDR3 memory doesn’t help AMD platform here. Both Intel Atom based platforms take the lead in WinRAR and 7-zip. This is one of those cases when Hyper-Threading technology comes in very handy.
We use Apple iTunes utility to test audio transcoding speed. It transcodes the contents of a CD disk into AAC format. Note that the typical peculiarity of this utility is its ability to utilize only a pair of processor cores.
Eee PC 1215B netbook with an AMD E-350 processor inside wins in this test with a great advantage. Now we see that Hyper-Threading technology can’t work its magic any more and processors on Bobcat microarchitecture offer higher individual core performance than Intel Atom CPUs. At the same time, Eee PC 1015B netbook with an AMD C-50 processor can’t boast the same brilliant results: its clock speed is only enough to help it catch up with Atom N570.
We measured the performance in Adobe Photoshop using our own benchmark made from Retouch Artists Photoshop Speed Test that has been creatively modified. It includes typical editing of four 10-megapixel images from a digital photo camera.
Here AMD E-350 processor can only outperform Atom N570, so Eee PC 1215N on Nvidia ION platform with Atom D525 processor inside becomes the fastest netbook for Photoshop. The Eee PC 1015B based on the junior Brazos modification turns into a total outsider here. Besides, Photoshop seems to be a too challenging application for netbooks anyway.
Excel performance is presented as the time it takes to complete calculations of an electronic table that uses Monte-Carlo algorithm for solving an economic problem.
Here Atom processors benefit a lot from Hyper-Threading support. Therefore, Eee PC 1215N and Eee PC 1015PE netbooks based on Intel processors get remarkable far ahead here.
We used Cyberlink Media Espresso 6.5 to test the video content transcoding speed. This utility is particularly fit for netbooks because it can employ the resources of different graphics cores, which makes up for the weak processors used in systems like that. We measured the time it took to transcode a short 2-minute H.264 1080p video clip into an iPhone 4 friendly format (H.264, 1280x720, 4 Mbps).
The ION based netbooks is an indisputable leader here. The thing is that only Nvidia GT218 graphics core supporting CUDA technology is capable of handling not only decoding, but also video stream encoding. Brazos based netbooks with Radeon HD graphics cores use their cores only for decoding, making computational cores take over the video stream encoding. That is why it takes them much more time to transcode the same video. Unfortunately, Eee PC 1015B netbook with an Ontario processor working at low clock frequency doesn’t do well here. It loses even to a Pine Trail based netbook, which can only use the computational resources of the Atom processor for encoding and decoding.
We also used Fritz chess benchmark to get a more complete picture of the platforms capabilities.
The two Atom based netbooks are ahead in this test, proving once again that Atom processors are faster than Zacate and especially Ontario in resource-demanding tasks that can be well-paralleled.
