    Re: AMD desktop CPU update - Wraith cooling, new APUs

    According to Anandtech the Athlon X4 845 should have clock speeds of 3.5GHz base/3.8GHz boost. Claimed IPC improvements for Excavator are 4% - 15%, which means worst case performance will be just a shade behind an A10 7850k, and best case will be around 10% faster. That's fairly tasty in a 65W processor.

    reviews of athlon x4 845 will be interesting, although the other APUs will be same old performance

    Re: AMD desktop CPU update - Wraith cooling, new APUs

    Surely it's a bit too close to AM4 for these - there's only a few months to go, so the new motherboards won't last long till they're outclassed by new motherboards with DDR4

    Re: AMD desktop CPU update - Wraith cooling, new APUs

    That Athlon looks very interesting as a home server CPU, if it wasn't for the fact I would have to spend another £20 on a GPU. With only 8 PCIe lanes, I wonder how that would split between the graphics card and second network card.

    No-one knows when AM4 will be released.

    Zen isn't due until year end, and AMD will have to decide how they overlap products and which market segment gets Zen first. The plan could easily be to release desktop CPUs with Zen at the same time as the new AM4 APUs with whatever the next construction core is going to be called, to ensure that there's a clear performance separation between the lines. if that's the case, we could easily not be seeing AM4 motherboards and processors for another 9 - 10 months. They need to so something in that time to keep people thinking about AMD as a CPU/APU provider.

    AMD still offer good value, but I think there's a recognition that they were starting to drift in terms of motherboard spec, particularly with the AM3+ platform. This is more a move to keep existing market share than gain new share - to keep the people who want to build AMD but are worried about losing out on M.2, USB3.1 etc. At the end of the day if you need to build a PC now, AM4 coming out later this year isn't much use to you. At least AMD are doing something to try to persuade those people to build AMD....

    I suspect it'll be hard wired x8 to the primary PCIe slot - AFAIK the secondary on most FM2+ boards runs at 2.0 x4 off the chipset anyway? How it'll play out on a board that splits the APU PCie lanes is anyone's guess. Stick to an A58 board and that shouldn't be an issue, though?

    EDIT: officially only the A88X supports splitting the PCIe lanes anyway. Apparently the A58 has just been replaced by the A68H (less SATA/USB ports but includes SATA 3/USB 3) anyway, but any of those boards with 2 PCIe x16 slots are running at least one of them off the chipset

    "Replaces the previous stock thermal solution at no additional cost..... original thermal solution will continue at new price"

    That kind of spin really pisses me off. Had the price reduction on old stock happened yesterday, they would have to say the new thermal solution does cost more. If your product is more expensive to produce and you think its worth the extra cost, then say so, dont try and muddy the waters by claiming its free when its not, which makes it sound worthless anyway.

    oh how I love 'marketing' spiel... 2x Multithreading Capacity of the i5. Well I would hope 8 'cores' are better than 4 in capacity, shame the actual performance isn't that much better.

    Re: AMD desktop CPU update - Wraith cooling, new APUs

    The A10 7860K with a 65W TDP is replacing the A10 7850K,A10 7700K and the A10 7800.

    Companies seem to insist on using 4 digit numbers for their products, but the last digit is usually zero so really only three digits. Not surprising that numbers are coming around again and again.

    4670 makes me think of the GPU first, then I have to remind myself it is an i5 these days.
    8800 was a PA-RISC chip, a graphics card, a Xeon, now an AMD laptop APU.

    Waiting for someone to bring out a 6809 CPU, my old 1980's Dragon32 could do with an update

    Re: AMD desktop CPU update - Wraith cooling, new APUs

    Charlie adds some snippets: http://semiaccurate.com/2016/02/02/a...neup-for-2016/

    The Athlon is 65W TDP rated, but supposed to only actually use 50W.

    There is an A10 7890K coming. Would be nice if that was Carrizo with the graphics still enabled, but if AMD are squeezing decent performance now out of 65W then at 95W then might be able to bump the clocks up a bit on the old stuff.

    From what I gathered on another forum is that FM2+ cannot support the graphics part of the Carrizo chips due to lacking the necessary voltage regulation.

    Also,it Carrizo might not do scale as well at TDPs,since the whole design is orientated towards mobile and lower clockspeeds and the design is also much denser than Kaveri as its an SOC with similar surface area. Plus there is a reduction in the amount of L2 cache to 2MB for a dual module SKU and a reduction to 8 lanes of PCI-E bandwidth(unless there is additional bandwidth that can be provided by the motherbaord).

    I can't imagine doing crossfire high end GPUs on a quad core Carrizo, so I think the 8 lanes thing is fine.

    Graphics incompatible with FM2+ seems unfortunate, but originally Carrizo was slated to come out on FM2+ so it also seems odd.
