Previewing AMD's Brazos, Part 1: More Details on Zacate/Ontario and Fusion
by Anand Lal Shimpi on November 9, 2010 1:09 AM ESTThe Chipset err...Fusion Controller Hub
The Zacate/Ontario APUs have an integrated PCIe interface sporting 8 lanes. Four of those lanes are used for AMD’s Universal Media Interface (UMI) - a bus that links the APU to the Hudson FCH. The remaining four can be used for discrete graphics or a combination of discrete graphics and other PCIe controllers. Both PCIe interfaces can run at gen 1 or gen 2 transfer rates.
Display output naturally stems off of the APU. You can drive two displays in tandem over any combination of VGA or Display Port/DVI/HDMI/LVDS.
As I mentioned earlier, the APU sports a single channel memory controller - but you can install up to two DIMMs on that channel. Speeds are down from the 1333MHz system we tested at IDF, DDR3-1066 is the max you’ll officially see on a Brazos system.
The Hudson FCH supplies up to 14 USB 2.0 ports, 6 x 6Gbps SATA ports and another 4 PCIe lanes. The FCH is based on AMD’s SB800 series of South Bridges. Despite the small size, this is a full featured platform.
From the looks of it, AMD has all of the right ingredients for some very competitive entries in the mainstream and ultraportable notebook markets. Now it’s just up to the OEMs to build something cool out of it.
Check back in about a week for the full rundown on Zacate performance.

These are still not really hybrid processors. They've taken a GPU and a CPU (well, two of 'em) and stuck them on the same die. There's no sharing of resources between the two.A true hybrid chip would, in my opinion, share most of the hardware between the CPU and GPU. They'd share execution resources. For example, in these AMD chips, the CPU's SIMD instructions can't take advantage of the GPU's SIMD blocks, from what I'm seeing (forgive me if I'm misreading this all).

Have you seen AMD's roadmap for this? It can answer your question.TemplarGR - Tuesday, November 9, 2010 - link
This hardware is amazing, and has many possible uses. The most obvious is in netbooks and ultraportables: It will simply destroy the competition. AMD is right, what this market segment needs right now is more gpu power, not cpu. If their use case involved higher cpu usage, they wouldn't get a netbook or ultraportable anyway.This will also enable great tablets-ipad clones. Ideally a zacate tablet running Linux (for me).
I bought an Acer Aspire One more than 2 years ago, and i am frustrated by Intel policies. The GMA they paired original Atom netbooks with was garbage, consuming 5 times the power Atom consumed... And its performance sucks. Current Atoms still suck, although with more battery power, because Intel hates Atom since it has lower margins. They didn't really expect this kind of success, they didn't want to believe for most people cpu power is enough... They stopped advancing Atom so it is no wonder Netbook sales growth has reached negative numbers... But this tactic will become a boomerang for them...
It is nice seeing AMD making the hardware market exciting again!

Can't wait to see whatever numbers AMD lets you give us next week. Hopefully they'll be enough so I can decide whether to wait past the holiday season for Zacate or go with an N550 system now.rayson - Tuesday, November 9, 2010 - link
the total power draw for a netbook based on the brazos platform amd e-series will be 22-24 watts. the cpu performance for a amd e series will be equal to a core i5 520m.i got proof look at the other amd slideshows and videos they have done they have even shown avp running on 720p medium setting bit choppy though

CPU performance equal to an i5 520m? Thanks for the laugh. No way that is the case.rayson - Tuesday, November 9, 2010 - link
i am a intel fanboy but amd really will have me buying a netbook nowfic2 - Tuesday, November 9, 2010 - link
In the AMD Brazos Lineup table it lists:AMD E-350 2 1.6GHz
AMD E-240 1 1.5GHz
Seems like the clock speed of the E-350 and the E-240 are reversed unless the dual core does actually have a faster clock than the single.
I don't know why your spam program thinks my comment is spam.

Good article. I currently own a Intel SU4100 system (Gateway ec1430u). I am very interested in zacate platform vs. the intel SU processor platform. There are very few SU4100 + GPU platforms (read MAC Book Air and Zotac IONITX-O-E), so I hope your tests will include these systems as competitors.What is more interesting (to me) is AMD’s Universal Media Interface (UMI) and the Hudson FCH. A necessary upgrade for every ultra portable is a SSD. I hope we will see the SB800 chipset SATA6 performance. Also why isn't there any concern about the memory (CPU, GPU) bottleneck.
Staying tuned for the article next week and I hope to see benchmarks of the sata controller, especially SSD benchmarks, TRIM support, and overall SB800 throughput performance (USB, ethernet, etc).

Yeah, I have a gateway 1803 with a su3500 (core 2 solo 1.4) and even with only one core, it is fairly fast, much faster than an Atom with only a 5.5 watt TDP. I am not sure what the TDP of the graphics on the 945 is. The 945 graphics are certainly nothing real impressive, but they will do 720p youtube and accelerated ie9 beta is pretty fast. I see the Su line as the best competitor for the bobcat, and would like to see them compared.
