    Quantum3D Mercury brick

    Yeah, back in the day we used to fanboi on those cards in the 3dfx forums. They were "god-like" to us (the 200SBi boards that is).

    Quantum3D Mercury brick

    I remember those cards from back in the day. I still have a Quantum Obsidian X-24 with the Medusa cable. It's basically a sandwiched variant of one of those Obsidian 2 200SBi boards. This brings back memories :)

    AMD Announces The Radeon RX 480 Starting At Just $199

    Oculus are the ones who specced the R9 390 as being the minimum spec for VR. Valve followedsuit. So AMD is simply quoting them as it pertains to VR. I would assume that gaming wise... Polaris 10 is geared for 1440p gaming. You folks are unreal.

    AMD Announces The Radeon RX 480 Starting At Just $199

    AMD are not budget producers. Polaris 10 replaces the Radeon R9 380 series. Basically... Polaris 10 brings R9 390 series performance down to the R9 380 series market segment. Vega 11 will be the RX 490 series while Vega 10 will be the RX Fury series. AMD are not budget producers... they simply...

    From ATI to AMD back to ATI? A Journey in Futility @ [H]

    Read the original article from VentureBeat and not the interpretation from Ars. Koduri: It’s an architecture codename. It’ll still be Radeon something something on the box. But we didn’t have a consistent architecture name like our competitors do. It was hard, because for people, including...

    Ashes of the Singularity Day 1 Benchmark Preview @ [H]

    Pardon me if I come across as frustrated but I am. Since around July of last year I've been discussing these topics and all along the way I've received massive amounts of push back only to be proven right every time. I've corrected my knowledge, learned quite a lot along the way and have been...

    Ashes of the Singularity Day 1 Benchmark Preview @ [H]

    AMDs DX11 performance is a recent development for AotS. It is due to AMDs driver work and not due to anything on Oxide's end. What it shows is that AMD can optimize DX11 drivers but the manpower it takes to do so, and AMDs financials, don't really allow for AMD to do this routinely. The Star...

    Ashes of the Singularity Day 1 Benchmark Preview @ [H]

    Maybe I misunderstood what you stated but it seemed to me that you stated that Asynchronous Compute + Graphics was not enabled in the drivers at first, when it was. The feature was available in NVIDIA's driver. Asynchronous Compute + Graphics worked. When I say worked, I mean that Maxwell was...

    Ashes of the Singularity Day 1 Benchmark Preview @ [H]

    Are they doing it with DX11? If so then how can it be that Kepler can run PhysX when it does not support mixing Graphics and Compute together in parallel? Is Kepler executing concurrently instead? Most probable. Maxwell appears to execute in parallel, however, from the graphs I've seen from...

    AotS officially launched today, where is Nvidia's async driver?

    True, But what we do know is that originally, AotS attempted to run Asynchronous compute + graphics on Maxwell using the exposed driver feature. The result was an unmitigated disaster. Maxwell dropped performance into single digit-land. This prompted Oxide to code a separate path for the...

    AotS officially launched today, where is Nvidia's async driver?

    Yes, it is much higher than Kepler and Fermi but the question is... How does it perform compared to GCN. If the Beyond3D tests, which you commented on, are any indication it is that Maxwell's performance falls rather quickly compared to GCN based on the amount of concurrent kernels being...

    AotS officially launched today, where is Nvidia's async driver?

    A University led study published a short while ago. Let me find the link for ya. It also highlights some other interesting aspects of the Maxwell architecture. Like how it appears to have shrunk its memory controller logic, compared to Kepler, resulting in global memory efficiency of only 69%...

    AotS officially launched today, where is Nvidia's async driver?

    I'm not sure it would work well even if activated given that Maxwell SMs run out of local cache resources in between 16-32 concurrent Warps. Maxwell thus begins to spill into L2 cache more quickly than Kepler and even Fermi.

    Has Nvidia Forgotten Kepler? The GTX 780 Ti vs. the 290X Revisited

    SIGGRAPH, GDC etc. I've been following the talks and downloading all of the powerpoint and PDF presentations. As the XBox One and PS4 began losing steam newer workarounds were employed to use the idling compute resources over pure GPU front end performance. Just look at the titles released...

    Ashes of the Singularity Day 1 Benchmark Preview @ [H]

    So what AotS does is that both AMD and NV run a general path but vendor ID specific optimizations are thrown into the mix. Both NV and AMD had access to the source and could submit vendor specific optimizations. So on the whole, AotS is an example of a very well optimized DX12 Real Time...

    Ashes of the Singularity Day 1 Benchmark Preview @ [H]

    As for DX12, it ain't for Indie games. DX12 requires separate Vendor paths because of the fact that it is a closer to metal API. That means that it requires a large investment in time and effort to properly optimize the code so that it can run as well as possible across a wide selection of PC...

    Ashes of the Singularity Day 1 Benchmark Preview @ [H]

    It's the opposite. The developer Dan Baker (Kollock) stated that they're doing vendor specific optimizations. Both AMD GCN and NV Maxwell run on separate paths. There's a vendorID specific path for NVIDIA. Kollock also mentioned that they would disable Async by default for NV hardware of it...

    Unreal isn't vendor agnostic. Unreal has NVAPI embedded into it. Unity as well. Vendor agnostic would be something like CryEngine V.

    Ashes of the Singularity Day 1 Benchmark Preview @ [H]

    You can use a compute shader in order to do the same calculations. Given that DX12 pretty much requires separate IHV paths, then you can have the AMD GCN path performing CR by using an Asynchronous shader. I believe Dirt Rally did this and Deus Ex: Mankind Divided will be doing the same thing...

    Has Nvidia Forgotten Kepler? The GTX 780 Ti vs. the 290X Revisited

    While it is universal, it being Dynamic Memory, how it is used is what matters. With DX11, you can tweak your software driver so that it intelligently stores excess framebuffer data into system memory while retaining data requiring immediate use in the VRAM framebuffer. This is how AMD have...

    Has Nvidia Forgotten Kepler? The GTX 780 Ti vs. the 290X Revisited

    It is premature but the design time frame for Pascal doesn't appear to indicate that it will be drastically different from Maxwell. I could be wrong but that's my take on it.

    Has Nvidia Forgotten Kepler? The GTX 780 Ti vs. the 290X Revisited

    The console versions of those titles are drastically different. They were re-worked from scratch for the PC. The console titles starting with the end of 2015 and beginnings of 2016 kept most of their code optimizations intact. It's the pattern we've been seeing in most new game releases. One...

    Has Nvidia Forgotten Kepler? The GTX 780 Ti vs. the 290X Revisited

    Well I don't think Pascal will have Async Compute + Graphics support. I think Pascal will brute force its way to a win like the GTX 980 Ti did. As for Polaris, it will benefit from Async Compute...perhaps more so than previous GCN iterations due to the CU improvements.

    It It has nothing to do with DX12 or Async Compute. Heck we can leave DX12 and Async out of it. Take the 2015 titles. Isolate console vs non-console titles and this is what you get.. R9 290x vs GTX 780 Ti (non-console) 1080p: GTX 780 Ti is 8.3% faster 1440p: GTX 780 Ti is 1.7% faster R9 290x...

    Gears of War PC: A complete disaster on GCN1.2 cards in Microsoft's own game + API debut

    I know it's obvious but fans of both AMD and NVIDIA love to reject reason and instead cling to false hoods. Sourcing Dan Baker, for my comment, should help to over come some of that. I have the quote over at overclock.net too :)

    Gears of War PC: A complete disaster on GCN1.2 cards in Microsoft's own game + API debut

    GoW UE, whether AMD or nVIDIA lead, is not a true DX12 title. Fans on both sides keep claiming that a UE3 engine based game can truly take advantage of DX12 but that's not really possible. I spoke to Dan Baker about this as well as his opinion was that, absent a near complete re-write of the...

    Doom Alpha GPU test

    Not likely. ID stated that the performance, in the Alpha, was without PC optimizations. So we're looking at code which was optimized for the GCN architecture in the consoles with the Alpha. ID stated that they're working on PC optimizations. The 60Hz lock is also part of the console...

    [PCGH] Hitman DX12 Benchmarks -- 390 faster than 980 by 20%

    No, but the fences involved in Asynchronous Compute + Graphics do. You generally have one fence for the graphic context and a few fences (varying on how many concurrent compute jobs) for the compute context. The GTX 980 Ti was likely CPU/API bottlenecked at 1080p and under DX11. DX12 alleviated...

    Ugh? Nothing you said is true. I mean it's your opinion but it ain't true. Late summer last year? That was Fiji launching end of June-beginning of July. Polaris was known as Ellesmere and part of the Artic Islands architecture. It was aiming for a Q2/2H2016 release and is on schedule. As for...

    Rise of the Tomb Raider Graphics Features Performance @ [H]

    That's what I'm getting at. I think that CrossfireX + this memory management optimization from AMD might be causing PCIe bus saturation. It could also be: Higher API overhead/CPU bottleneck Or maybe these optimizations don't work with CrossfireX?

    Rise of the Tomb Raider Graphics Features Performance @ [H]

    The one limiting factor may be the PCIe bandwidth when operating under CrossfireX which uses XDMA. This might explain the bad scaling for Fiji with Crossfire under certain titles where the minimum FPS drops bellow 30.
