Updated: AMD 785G: The Venerable 780G, Evolved

Other 785G Goodies

AMD has a few more tricks up its sleeve with the 785G, including:

Lower Power Usage

It's hard to argue with lower power usage. AMD claims that the new Radeon HD 4200 IGP can dynamically scale IGP clock speeds based on usage requirements.

ATI Stream Technology

AMD's GPGPU solution is compatible with all Radeon 4000 series graphics processors, and that includes the integrated Radeon HD 4200. While both Nvidia and AMD make a lot of claims about processing all sorts of tasks on the GPU, there are precious few applications that take good advantage of either CUDA or ATI Stream.

It is interesting that we can now use an application that is optimized for both Nvidia's CUDA and AMD's ATI Stream to see which vendor’s IGP takes the best advantage of GPU acceleration. We'll try Cyberlink's Mediashow Espresso with the 785G chipset in addition to the GeForce 9300 chipset and see what happens. With no GPGPU solution of its own, Intel will have to sit this one out.

Windows 7 Support

Windows 7 has already hit RTM, and while it's nice to know that the 785G works with it out of the box, I'm not sure how many people are chomping at the bit to upgrade to an operating system the moment it's released. Still, there's certainly nothing wrong with timely Windows 7 support.

    the real question is how would this perform if mated to an Atom processor in an nettop.

    "refined architecture" ? To my knowledge, and please correct me if im wrong, all that was changed between the original phenom and the phenom 2 was the addition of more L3 cache allowing it to do more simultaneously and a die shrink allowing for higher clocks. That does not a refined architecture make. When AMD added an on die memory controller to their processors years ago they had made a huge advancement in architecture. Im sad to see them fall away from the performance crown. Here's hoping their new Bull Dozer architecture brings something genuinely intriguing to the table.

    ^^^ and support for DDR3. Although thats a change to the board, not the CPU.

    Very interesting.
    A integrated GPU that can game. =D

    Makes my lil Pentium D with a 4670 seem puny...
    3.3GB/s memory bandwidth (single channel DDR2 533... though 2 sticks, it runs in single channel... damn prebuilts) also seems sad on my rig...

    Good question. A dual core Atom with a 4200 integrated would be nice.
    We all know Intel makes shitty mothebroards and AMD makes kickass motherboards anyways.

    Not correct, the P2 has a built in memory controller so the switch to ddr3 affected that controller

    Native ram for a pentium d is PC4200 which has a max of 4.2gb/s per channel etc and the FSB has the max of 6.4gb/s

    The Intel atom would most likely underpower any video card out there, and Intel does actually make a good reliable business platform where video performance is not required etc

  • I'm sorry, is this an Intel benchmark site? All other reviews put SYSTEM power consumption for Athlon II 250 well below Intel E7200.

    This article raised a lot of questions for me. What about Hybrid Crossfire for example? What kind of cards can be used together with this new IGP? Is the discrete graphics card on standby if no performance is required? If no then how much extra outlet wattage is expected? And how much extra if actively in use? I'm interested in using the 785G solution in the 24/7 HTPC setup with the possibility to do occasional gaming as well. My current setup with 690G chipset and Athlon 64 X2 BE-2350 CPU draws around 50 watts most of the time and up to 90 watts under heavy load. Is it too much to expect similar levels from 785G and Phenom II X3 705e combo for example?

    when can we see the mobile version of this? this is most certainly a welcome update compared to the 780g-hd3200 chipset. and beats any nvidia igp hands down. id love to see this on an $700-$800 laptop. good thing im still holding back on buying a new notebook.

    Good timimg, I was wondering if 785G is better than 790GX or not yesterday. Thanks.
