    Re: AMD Vega GPU architecure uncovered

    So when do we get to see the cards?

    I'm planning a Ryzen / Vega build in Q2

    AFAIK they're still slated for release in Q1, but that could mean anything up to the end of March...

    Looking forward to Raven Ridge implementing these improvements. Now give me Bristol Ridge already!

    Re: AMD Vega GPU architecure uncovered

    ...uh, is that it?

    Did AMD's marketing department make a big song and dance about how good Vega is on paper - leaving out details like RRP, lineup specs, release date?

    Want to know what is more impressive than Vega is on paper? Releasing something that is at least 95% as good nearly 8 months ago.

    Maybe that is why the 1080 ti never appeared. Looks like AMD and Nvidia are trying to launch to get one up on each other. Wouldn't be surprised if Shield was Nvidia's plan B announcement.

    Quite possible. There is certainly no reason to release the 1080 Ti when they can continue charging £600+ for a chip as small as the 1080.

    In fact given how big Vega is (and how long the GP102 manufacturing process has had to mature) they might be better off releasing a 1090 and 1090 Ti. Then, as AMD releases it's 1080-beater nearly a year after the 1080 was launched, nVidia turns the 1080 into an upper midrange card.

    I intended to build a high-end Ryzen/Vega machine, but everything AMD is doing is arriving far too late.

    Re: AMD Vega GPU architecure uncovered

    To be fair to AMD, there was no point them even thinking about releasing an HBM2 card until there was good reliable supply of HBM2 available. Particularly since the first Vega card is using the smaller Vega chip and will be expected to ship in reasonable volume. No HBM2 = no cards in the channel.

    We'll see if nVidia relase those details about their product, but I wouldn't be surprised if they didn't either they are very commercially sensitive and are exactly the kind of thing both nVidia and AMD keep under wraps until later since there's little a consumer can do about it now anyway.

    Re: AMD Vega GPU architecure uncovered

    The GPU seems to be 500MM2+ so I suspect AMD will be targeting the GTX1080TI and Titan X.

    Marketshare matters! Game on Intel IGPs! Makes gaming a unique experience!

    AMD can update their webpage http://www.amd.com/en-us/innovations...raphics/stream

    and say any modern card with stream processors on can be used like CUDA with AMD's own openCL, instead of telling everyone they need a firepro card

    My guess is around 460mm2.

    Which isn't what the page says at all. It refers to a combination of technologies, collectively branded as "Stream", that are optimised for compute workloads via OpenCL. One of those technologies is ECC memory, which is only available on the FirePro cards. So if you want to use the optimised Stream technologies, you do need a FirePro card.

    Nowhere on AMD's website does it say you can't use OpenCL with consumer gaming cards. They only advertise the capability for professional cards, but frankly anyone who needs GPUs for compute workloads and isn't tech-savvy enough to know that you can run OpenCL on AMD's consumer cards should probably buy a professional card anyway, as they're likely to need the improved/dedicated support.

    EDIT:

    Here's the compatibility statement on the AMD OpenCL 2.0 driver download page (http://support.amd.com/en-us/kb-arti...-Driver.aspx):

    The AMD OpenCL 2.0 driver is compatible with AMD graphics products based on GCN first generation products or higher.
    If you're not tech savvy enough to find and understand that, you probably shouldn't be running OpenCL on consumer cards...

    the page is saying you need a firepro card, if you don't have the time for more useless information after trying to find what you need on MSDN while nvidia has a whole subdomain dedicated to cuda, which easily destroys openCL rendering in blender and other 3d programs, so if you look into all the opensource drivers for openCL, then those would probably not be using stream processors on normal RX or R9 cards for all the floating point math

    The page is about firepro graphics cards. It's right there in the url. The specific technology stack it's talking about - Stream - only works on firepro graphics cards. Stream != OpenCL. OpenCL runs on all AMD GPUs (you need GCN for OpenCL 2.0). Stream is only applicable to firepro. These are different things.

    And I'm afraid I simply can't parse the rest of your comment into something meaningful. AFAICT it boils down to a claim that cuda > opencl therefore nvidia > AMD?

    Comparing OpenCL to CUDA is pointless - OpenCL is an open standard for compute that can run on any GPU/CPU/accelerator with appropriate drivers/software, while CUDA is a proprietary software stack that only runs on nvidia cards. Of course nvidia invest a lot more effort into pushing CUDA - it ties people to their graphics cards and makes them money. Besides, the first google result for 'AMD OpenCL' is http://developer.amd.com/tools-and-sdks/opencl-zone/ - compare that to the first result for 'nvidia cuda': http://www.nvidia.co.uk/object/cuda-...puting-uk.html ... I'm not seeing a huge amount of difference in the level of content available between those sites...
