Heavy Lifting: Performance in Complex Workloads

Brazos is clearly faster than Atom in light workloads, but what about in more complex/heavier applications? Are the Bobcat cores enough to allow E-350 systems to move up in the world or will they still be confined to the web browsing/email usage models of netbooks? I've run the E-350 through our entire Bench suite to find out. If you want the full gamut of results head over to CPU Bench, but I've chosen a few here. I also included performance results from a 2.66GHz Pentium 4 to put things in perspective for users of really old systems.

Adobe Photoshop CS4 - Retouch Artists Speed Test

Photoshop CS4 performance is not half bad on the E-350 compared to other similarly priced platforms. Also impressive is the E-350's performance advantage over the old Pentium 4. Compared to the Athlon II X2 however the E-350 is still noticeably slower.

The standings and performance trends continue in our x264 encode benchmark. I don't expect you to do a lot of video transcoding on the E-350 as it's not much faster than Atom here. VIA's dual-core Nano is a bit quicker but still not enough to make this a viable usage case.

Windows Media Encoder 9 x64 - Advanced Profile Transcode

Windows Media Encoder provides a far lighter workload, but the standings don't change. The E-350 is faster than anything Atom based, faster than the old Pentium 4, but slower than VIA's Nano X2.

Cinebench R10

While I don't expect E-350 users to do any offline 3D rendering work, Cinebench does give us a good characterization of single threaded performance. The problem with Atom is that its single threaded performance isn't nearly as good as its multithreaded performance. In all of the previous benchmarks an Atom D510 is clearly quicker than the old 2.66GHz Pentium 4, but looking at single threaded Cinebench R10 you get a different story entirely. The P4 has nearly twice the single threaded performance of an Atom D510.

The E-350 is still a bit behind the Pentium 4 in single threaded performance, but it's not nearly as bad as Atom. The out-of-order execution engine helps tremendously here. What you get as a result is a system that doesn't really feel slower than a 5 year old PC but has the features of a more modern system.

Overall the E-350 is clearly faster than Atom ever was at running these heavier workloads. The highly threaded workloads aren't much faster on E-350 vs. Atom thanks to the latter's Hyper Threading , but single threaded performance continues to play an important role and is a huge advantage of AMD's. VIA's simple out-of-order architecture is consistently faster than the E-350, however I don't expect to see widespread adoption or support for VIA's platform (at least compared to AMD's). Compared to the larger out-of-order x86 cores the E-350 is still in a lower performance class, the Athlon II X2 is easily twice as fast as the E-350 in these tests.

Ultimately the same rules that applied to Atom based systems apply to Brazos systems:

1) Swapping to disk is painful so you need enough memory (I'd recommend no less than 2GB for Windows 7, ideally 4GB) and you'll want a fast HDD. My preference is still an SSD, even a low end value drive over even a fast hard drive. Even a low end SSD (e.g. Kingston SSDNow V100) will make a Brazos system feel acceptably fast.

2) Outside of media playback and some gaming, you're still limited in the types of applications and workloads you can run on Brazos. The Brazos platform is great for web browsing/email workloads, but don't try to do too much more with it. The advantage over Atom here is that Brazos just does those things noticeably faster.

    I was wondering if it is possible to overclock this mobo+APU combo? Reply
  • allzhat - Thursday, March 15, 2012 - link

    I use K10stat to increase the multiplier for my notebook (e350) from x16 to x18 (1800Mhz)or even x22 (2200Mhz), but I can't feel more performance for this APU but it draw more power consumption and heat of course

    I suggest to use gamebooster for heavy application

    PS: I'm sorry for my bad english

    So an SSD really makes difference on Brazos platform? Now I can place my order :)

    My choice is Corsair Nova 64GB since it is the cheapest drive with the minimum accpetable space I need. Any drive cheaper than this one is not big enough and bigger ones are more expensive... Hope its low Random Read performance doesn't impact much, at least faster than an HDD!

    Being cheap with SSDs? Good luck when you suffer reliability problems with your SSD. Reply

    Guess what? Somebody ran an durability test for an Intel X-25V, a non-stop read--write-erase cycle for 300 days and still working. Performance began to drop after 6 months, but keep in mind that this stress test is over 20 times beyond daily use. So it actually takes years to destroy an SSD, without SF controller, of course :) Reply

    A sample of ONE is by no means enough. The same person could have tested a second SSD and have it die on him after a week.

    After all that's what MTBF is all about - the average time for a failure in a population of identical devices.

    Is it me or the Nano X2 just beats the crap out of both Brazos and Atom? Can we get a review of that chip, Anand? Reply

    Not a full review but darn close.

    they did, its here:

    Problem is that what they tested was basically an engineering sample built on the wrong node, they havent gotten anything to market yet, so actual numbers from real products are unknown. having said that, yeah it does look like it might be better, but until someone makes a product based on it, we'll never know.
