AMD Fusion: Brazos Gets Previewed: Part 2, Performance

AMD gave us an opportunity to go hands-on with its upcoming Brazos platform--the only preview you'll see before this technology surfaces in retail notebooks. Is it fast enough to compete with the Nehalem-based competition, and cool enough to trounce Atom?

AMD Fusion: Brazos Recap, Power, And Heat

One week ago, we went over the details on Brazos and Zacate. Today, we are finally allowed to go release our benchmark numbers. If you haven't read our earlier coverage, it's a good time to go back and go over all the nitty gritty details on Brazos, Zacate, and Ontario.

A quick recap:

Bobcat: The processing architecture behind AMD's upcoming Zacate and Ontario APUs.

Brazos: AMD's 2011 platform for the ULV Zacate/Ontario APU + SB750 southbridge. It effectively replaces the high-end parts of the Nile platform.

Because we were dealing with notebooks, we often have no way to control memory timings. Given that platforms often ship with memory specific to that product line, we tried not to alter memory module configurations.

    Looking extremely impressive AMD, where as before you were a full gen behind, now id just say half gen. Make BD a big success, and you will most definitely get back in the game, however i doubt it would be enough to take the lead.

  • did you realize that sometime it's as fast as the i3 with 2,2ghz?

    If an Intel processor and an AMD processor were exactly the same - 9 out of 10 'normal' people would choose the Intel

    The only people "in the know" are in the enthusiast segment of the market, which is a very small slice really.

    Its a constant uphill battle for AMD, but then again, if they didn't exist, we'd all be paying through the nose for slower processors

  • I don't like when Tom's trow at us many facts from the AMD crowd to brainwash our mind. I don't like when the game is to convince the community to buy something who is not proved again.

    "The new AMD Fusion developer "trust fund" is actually a great way to start chipping away at the current CPU-heavy mentality." Yeas and we are also GPU-heavy mentality too!!!

    Who the hell plays games on a netbook? Another spectacular fail for AMD.

    Probably not a lot of people, but when netbooks have the capability to play at acceptable levels for the masses, they will be great.

    Nifty, an the best thing about AMD making high end competition for intel is price drops lol, if AMD can pull it off.

    Even more interesting would be a tablet that can be used to play games!
    So it could mean that we can read e-mail, read e-books watch movies and internet pages and even play with tablet-PC. Netbook is just one step ahead... Yep it is not the same as Nvidia 460, even 350 or amd 5650 from the low end (gaming), but the resolution would be smaller, so it would be possible.

    Let see what we get when this is really out.
    All in all it gives people a choice. Need more CPU and very rarely GPU power... take intel... If you don't need so much CPU power, but need GPU power chose AMD. It's good to have altenatives!

And when the user picks Apple the CPU manufacturer is absolutely out of question.
