The Brazos Performance Preview: AMD E-350 Benchmarked
by Anand Lal Shimpi on November 16, 2010 12:01 AM ESTSetting Performance Expectations
AMD provided this slide of PCMark Vantage and 3DMark Vantage performance of Brazos compared to its existing mobile platforms (Danube and Nile):
If you look at the PCMark Vantage numbers you'll see that AMD's E-350 provides roughly the same performance as an Athlon V120. That's a single core, 45nm chip running at 2.2GHz with a 512KB L2 cache. Or compared to a dual core processor, it's within striking distance of the Athlon Neo K325 which features two cores running at 1.3GHz and 1MB L2 per core. The GPU performance however tells a very important story. While AMD's previous platforms offered a great deal of CPU performance and an arguably imbalanced amount of GPU performance, Brazos almost does the opposite. You get a slower CPU than most existing mainstream platforms, but a much better GPU.
In the sub-$500 market, you're not going to get much in the way of a discrete GPU. What AMD is hoping for is that you'll be happy enough with Brazos' CPU performance and be sold on its GPU performance and total power consumption. From AMD's standpoint, there's not much expense involved in producing a Zacate/Ontario APU, making Brazos a nice way of capitalizing on mainstream platforms. The 75mm2 die itself is smaller than most discrete GPUs as well as anything Intel is selling into these market segments.

The Comparison
Brazos, like Atom, will fight a two front war. On the one hand you have the price comparison. The E-350 will be found in notebooks in the $400 - $500 range according to AMD. That puts it up against mainstream notebooks with 2.2GHz Intel Pentium DC and 2.26GHz Core i3-350M processors. Against these platforms, Brazos won't stand a chance as far as CPU performance goes but it should do very well in GPU bound games. I've included results from a 2.2GHz Pentium dual-core part (1MB L2 cache) as well as a simulated Core i3-350M in the mobile IGP comparison.
The other front is, of course, the ultraportable space. Here you'll see the E-350 go head to head with dual-core Atom, Core 2 ULV and Arrandale ULV parts. AMD's CPU performance should be much more competitive here. From this camp we've got the Atom D510 (close enough to the N550) and a simulated Core i3-330UM. The expectations here are better CPU performance than Atom, but lower than Arrandale ULV. GPU performance should easily trump both.

TDP doesn't mean real world power consumption, I think you should look at a few other reviews first who did a better compare.... Zacate even owns atom 525 big time with ION and even better then single core atom.... what TDP again? :)http://hothardware.com/Reviews/AMD-Zacate-E350-Pro...

No, it isn't.E-350 has the same number of cores as I7-680UM(top of the line Intel CULV Processor that is supposedly available but nowhere to be found), higher frequency, better IGP and it comes at a far cheaper price.Also, Sandy Bridge, at its launch, won't bring new CULV chips, because the current line has been out for less than 6 months.So, no more competition for this segment.

NST im not sure what your point is, yes the E350 has the same number of cores and the same TDP as all core i3/i5/i7 ULV parts, I'm not sure about price but they can be found in a variety of laptops, from the lenovo u160,u260,u460s, .... well almost every mfgr has a shipping laptop with a core iX ulv part (sans apple).laptops with these parts have been purchasable since june, and the e350 is only benchmarkable via an engineering platform... so its not exactly that close to market... even if it was.. seems like it can't compete vs core ix ulv. on anything other than price.
maybe if its super-cheap, it'll sell in a few netbooks vs atom.

1. E-350 has much better power consumption.2. E-350 has better GPU performance.
3. Intel CULVs are based on a better architecture however, E-350 has a higher frequency, which is crucial for 720p gaming.
As a gamer, what I see here is the potential for ultraportable notebooks with gaming performance close to this of Alienware M11x and never before seen battery life at the cost of an Atom-based netbook.
I do not question Intel's current supremacy in every segment but I think that next year Intel will face some strong competition from AMD.And that's good for us customers.

And you forgot the most important point - Brazos is playing in a completely different price bracket.The Atom price bracket.
Dark_Archonis - Tuesday, November 16, 2010 - link
Brazos is aiming at the $300-500 market. Guess what, there are some Celeron systems that fall in that price bracket as well.8steve8 - Tuesday, November 16, 2010 - link
1. does it have much better power consumption? the tdp's are the same, ive yet to see ulv arrandale vs e350, total system power consumption.2. yes, it has better gpu performance
3. the e350 has higher non-turbo frequencies than ulv arrandales, but why do you think that's crucial for 720p gaming... by that logic the 3.6Ghz pentium 4 is better suited for gaming than a 3Ghz sandy bridge cpu... which is false.

1.All you got to do is check the review of a laptop featuring an Arrandale ULV chip and then compare the power consumption.There plenty out there.Plus AMD stated that E-350's idle power consumption would be even lower in the final product.3. 720p gaming--->More CPU dependant
1080p, 1600p etc--->More GPU dependant
Generally about gaming, in higher resolutions, GPU becomes more and more important than the CPU.What I meant was that in a game that utilizes 2 cores E-350 will have an edge due to the higher frequency.And yes, if you find a game that utilizes only one CPU core (probably an old one) the Pentium will probably manage to hold his own against Sandy Bridge.

1. How about the ~10W consumption of the Alienware M11x R2 while running the Anandtech Internet battery life test? That's a i7-640UM that'll ramp up to 2.27GHz when it's needed.With respect to other power consumption figures... It's mildly annoying how other sites are typically comparing desktop/'nettop' systems to the 'brazos' demo platform. After all, take a look at the power consumption of any actual notebook/netbook implementation of the same processors and suddenly the power consumption numbers of the 'brazos' demo platform is simply in line/above the competition rather than far below it...
If interested in other power numbers, the Anandtech "Intel Core 2 CULV Roundup" published earlier this year has some good figures for both atom and CULV. For example, the Asus 1005PE with the single-core atom N450 at 1.66GHz consuming a massive 9.5 watts under 100% CPU load. So theoretically an N550 with its 3 watt higher TDP would get up to all of 12.5 watts... Of course more interesting is the fact that the 1.3GHz CULV notebooks in that review are at all of 19 watts under 100% CPU load - so comparable power consumption, despite being faster and on a 45nm process tech instead of 40nm (though the Intel 45nm is roughly equal to TSMC 40nm, if not better.)

Do you see those ULV chips selling for Atom prices as Zacate and Ontario are ?You are comparing an enduro to a moped while complaining the latter is slower.
Hell it is. IT IS SUPPOSED TO BE.
The fact that Zacate is actually considered an alternative to ULV series at 1/3 the cost is a HUGE success on itself.
