Performance in Applications
To estimate the average performance in popular applications we used Futuremark PCMark 7 benchmarking suite. We worked with three benchmarks from this suite: general score test, lightweight test for low-performance systems and productivity test emulating user’s work in office applications.
The Atom N2800 is close to the Atom D525 in performance in the last two tests, but the newer CPU enjoys a hefty 26% advantage in the overall score. It’s because the Cedarview Atoms feature a new and faster graphics core which helps them do better in the graphics tests included into this trace. On the other hand, they still cannot beat the competing AMD E-350 which delivers higher performance three times in a row.
By the way, take note that the gap between the senior and junior Atoms of the new generation is no larger than 9%. It means the lack of Hyper-Threading in the D2500 is not a big problem for real-life applications, at least according to PCMark 7.
It’s quite normal for the new Atom to be a little faster than the older one, but there’s one peculiarity about the results. The Hyper-Threading technology doesn't seem to accelerate the web-browsers in some cases. We have no other explanation of the Atom D2500 being ahead of the Atom N2800 in the Peacekeeper test.
The AMD Zacate CPU beats every Atom once again. It looks like the Cedar Trail will have a hard time trying to shake the market positions of the Brazos platform, at least in the office nettop segment.
To test the processors performance during data archiving we resort to WinRAR archiving utility. Using maximum compression rate we archive a 715 MB folder with multiple files.
The Cedarview is about 5% ahead of the Pineview at archiving data but the more interesting fact is that the Hyper-Threading technology is highly useful here. Thanks to it, the Atom N2800 beats the AMD E-350 and is over 17% ahead of the Atom D2500 which lacks Hyper-Threading.
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.
The gap between the Atom N2800 and Atom D2500 widens when they process images. The Cedarview without Hyper-Threading is slower than the AMD-E350 whereas the flagship Cedarview model is ahead of the latter. The difference between the Pineview and Cedarview series amounts to 3% again.
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 create single-threaded load.
The Atom N2800 is close to the Atom D2500 in performance here. They are hardly any faster than the Atom D525 and only enjoy a small advantage due to the increased clock rate. The best results are delivered by the AMD E-350 as is often the case under single-threaded loads.
In order to measure how fast our testing participants can transcode a video into H.264 format we used x264 HD Benchmark. It works with an original MPEG-2 video recorded in 720p resolution with 4 Mbps bitrate. I have to say that the results of this test are of great practical value, because the x264 codec is also part of numerous popular transcoding utilities, such as HandBrake, MeGUI, VirtualDub, etc.
It is the Hyper-Threading technology that can give the Atom CPUs an edge in certain applications. As you can see by comparing the results of the N2800 and D2500, its benefits can amount to 40%! It's no wonder that the senior Atom CPUs of the Cedarview and Pineview series are considerably faster than the competing processor from AMD under high multithreaded load. Interestingly, the Atom D2500 is also no slower than the AMD E-350 here, although lacks Hyper-Threading.
We will measure final rendering speed in Maxon Cinema 4D using special Cinebench benchmark.
The new design and 32nm tech process ensure a 7% advantage for the new Atom processors here but that’s not enough for the Atom N2800 to beat the AMD E-350. Of course, Intel has got the faster Cedarview D2700 but it's out of mass production already, so its availability is going to be low.
Following our good tradition we also added Fritz chess benchmark to our testing suite:
This chart doesn’t show us anything new. Fritz Chess Benchmark being a multithreaded application, the Atom N2800 beats the Atom D525 by about 6%. The Cedarview with Hyper-Threading is almost 50% as fast as its cousin without Hyper-Threading. As a result, the Atom D2500 is slower than the AMD E-350 whereas the Atom N2800 is faster than the latter.
