The Brazos Performance Preview: AMD E-350 Benchmarked
by Anand Lal Shimpi on November 16, 2010 12:01 AM ESTDesktop IGP Comparison: Faster than Clarkdale
I split the graphics comparison into two sections: desktop and mobile. For the desktop section I compared the E-350 to the latest Clarkdale chips, AMD's own 890GX and a discrete Radeon HD 5450 graphics card. While the Radeon HD 5450 has the same number of shader processors as the E-350 (80), they run faster and it has a dedicated 1.6GHz memory bus to feed it. The E-350 has to share memory bandwidth between the two Bobcat cores and the 80 SPs, severely limiting its performance potential.
The E-350 does extremely well compared to its desktop brethren. In our Modern Warfare 2 and BioShock tests its easily faster than the Core i3/i5 and in the case of BioShock 2 it's even faster than AMD's 890GX. Dragon Age Origins is another story however as the benchmark is primarily CPU limited, giving the desktop parts a huge advantage. In GPU bound scenarios, it's clear that our initial Zacate benchmarking was accurate: the E-350's Radeon HD 6310 is quicker than Intel's HD Graphics.
Compared to the Radeon HD 5450 the 6310 offers between 66 - 69% of its performance in our GPU bound tests. The performance reduction is entirely due to the 6310's limited memory bandwidth being shared with the dual Bobcat cores on-die.

sure, they run at different frequencies, and if you could turn up the clock speed of zacate's GPU, then it might be the champ. But as it stands now, in the real world, according to anand, there is NO zacate GPU that can run that fast. Regardless of wishful thinking, the best Zacate only won one test, out of three, against intel's GPU.Can ANYONE (besides AMD's propaganda demo) show ANY more benchmarks where Zacate or Ontario or Brazos can beat Intel's Clarkdale integrated on-chip graphics?

The CPU performance of this product line is way below what i expected from AMD and the hype around it's architecture. Brad Burgess and his team should go back to the white board and refine their way of tackling the given performance/power constraints without sacrificing this huge CPU performance. Bobcat is OoO arch. even though it can handle 2 threads as opposed to 4 threads in Atom, it should give a marginal advantage. 18 w is still not a tight constraint to justify the poor performance I see in this overview.I'm really disappointed. Many architectural details of this processor will be similar in the Bulldozer design. I hope the latter won't carry the same degree of failure.
I totally agree with some inputs here .. what's the point of having a discrete-class graphics perofmrance in a machine that barely faster than the crappy Atom-based counterparts??

>>> "what's the point of having a discrete-class graphics performance in a machine that's barely faster than the crappy Atom-based counterparts??"and of course AMD is hyping the graphics performance too: i keep hearing that it's faster than the integrated graphics on an Intel Core i5 661, yet there is no evidence of that.
do not fall for the propaganda: the GPU part is NOT stronger than the current integrated crap from Intel, or nVidia's ION, or even AMD's Radeon HD 4290 integrated graphics.

IMO, AMD has the full capacity to deliver the competitive GPU performance level they want. Their graphics division is doing extraordinary job, and I don't think intel will EVER be able to catch AMD in the graphics part.What i'm really worried about, for the sake of our interests (the customers), is the terrible progress this company has made in the CPU development since 2005 compared to the giant chip. After the uter failure of Intel's Larrabee project, AMD now becomes the only entity in the world that has x86 license and the necessary technology to fuse high class GPUs and x86 processors into heterogeneous cores with overall performance never seen before. It's really sad to see how the outcome of "Fusion" starts out this way. I hope the upcoming products live up to the hype of this very promising project.
From marketing point of view, Brazo platform will take some attention only if it's "dirt cheap" .. I don't like this path AMD been taking last few years in the CPUs.

Anand, I believe you forgot Amd's predecessor in this market in the neo and 750 combination. I think this is where Amd is positioning their Zadcate chips. Could you add this combination in you next benchmarks?phillipguy - Monday, April 25, 2011 - link
I know this is an older post but I was thinking of buying the Sony VAIO VPC-YB13KX/S 11.6-Inch Laptop.From what I read I believe this AMD E-350 has better performance than my Atom 330 on my Asus Eee PC 1201N. (Correct me if I'm wrong)
My question is does the AMD E-350 have AMD-V support?
I ask because I will be running Ubuntu Linux as my operating system but I'll also like to run Mac OSX Server in a Virtual Machine (virtual box) however it requires hardware virtualization.
(Sorry if you mentioned this in your post however it's a really long and I understand about 20% of it all) LOL
THANK YOU!!

yes, it support amd-v
