[Guru3D]AMD Teases PCs with Radeon Fury X2 Dual FIJI GPUs - Page 4

post #31 of 45
This is going to be an awkward product launch.

Sure it'll have the power to plough through pretty much everything but that's alot of GPU power for a measly 4GB framebuffer per GPU for a dual GPU computational monster.

With the increase in video memory demands in some of the more demanding titles this could create issues if the games are running at their highest settings and higher than 1440p resolutions.

VR shouldn't be much of a worry though as none of the current VR headsets have displays that are higher than the combined 2160x1200 resolution, however I'm not sure of the memory demands of a VR setup.

The next generation GPUs are also launching this year with HBM2 and possibly GDDR5X, but they might not be able to put out performance close enough to a dual FIJI GPU.

Could it be possible and practical to revise the Dual FIJI GPU and add HBM2 to it? This would allow for more than 4GB memory per GPU. It could also be a factor behind the delays of this GPU. thinking.gif

AMD Dual-Fiji “Gemini” Video Card Delayed To 2016, Aligned With VR Headset Launches

Quote:
With winter upon us, I reached out to RTG last night to find out the current status of Gemini. The response from RTG is that Gemini has been delayed to 2016 to better align with the launch of VR headsets.

The product schedule for Fiji Gemini had initially been aligned with consumer HMD availability, which had been scheduled for Q415 back in June. Due to some delays in overall VR ecosystem readiness, HMDs are now expected to be available to consumers by early Q216. To ensure the optimal VR experience, we’re adjusting the Fiji Gemini launch schedule to better align with the market.

DX12 is also believed to be able to combine memory pools of multi GPU setups, but we don't know how well this will work, how practical it will be and what developers will take advantage of this for their games. And also, what about the hundreds of DX11 games?

I don't mean to sound negative or anything, I'm honestly genuinely worried about this.
Look at the amazing longevity of the Radeon 7990 and the R9 295X2, they pretty much bested NVIDIA's competing dual GPUs.

The large framebuffer of 3GB for the 7990 was apart of this and is a factor which helped it beat the GTX 690.
The R9 295X2's pricing is what made it alot more affordable and feasible to consumers, as-well as it's 4GB frame buffer.

In all fairness NVIDIA didn't response really well to AMD's 295X2. They launched the TITAN Z which was a 12 GB dual GPU card with 6GB per GPU, but it's pricing was insane which made it completely uncompetitive with the 295X2 for gaming purposes. It has other uses, but in terms of gaming it was not a justifiable purchase at all.

GeForce® GTX TITAN Z is a gaming monster, the fastest graphics card we’ve built to power the most extreme PC gaming rigs on the planet. Stacked with 5760 cores and 12 GB of memory, this dual GPU gives you the power to drive even the most insane multi-monitor displays and 4K hyper PC machines.

Good thing you're not alone on this planet then eh ? lol


But yea this card comes way too late, and 4gb per card ? that's not serious, first with Fury, it didn't make sense, but now with a x2 Fury.. it would make even more sense to have at least 8gb.

It is nice for itx builds however i would be more interested in 8 way crossfiring it. But we have a while before DX12 really is used so newer cards will be out before 8way crossfire really becomes do-able.

Newer cards are not going to make the Fury X2 go away any more than newer cards have been able to make the 295x2 go away. The card will be relevant for a long while, but I do agree that DX12 / Vulkan VR titles through 2017 - 2018 will eventually need to unlock the full 8GB on the card.

But in the end, if it runs well with an Oculus / Vive, it's not like consumers are going to drop their $600+ headsets immediately for Rev. 2 when they come out.

EDIT: I wrote way too much!

I thought I remembered reading something about AMD working on dual GPU solutions specifically for VR. It was along the lines of each eye gets a dedicated GPU, and thus I would think that is just the res of each eye that the 4gb buffer has to worry about.

Found it- it's called Affinity Multi GPU http://www.anandtech.com/show/9043/amds-liquidvr-announced-amd-gets-expanded-vr-headset-functionality

The GPU wasn't installed and the system wasn't fully assembled.
This is more realistic:

@TopicClocker and @Ultracarpet
I agree, there is the vr route, however this is based on the same underlining API. Mantle and DX12 will be capable of doing 1/2 render type of thing, so you have 2x4GB to use and each will display on 1/2 of the display.
http://www.guru3d.com/news-story/both-mantle-and-dx12-can-combine-video-memory.html

There's a couple of ways to this via Mantle; similarly to multiprocessing programming mantle gives the developer a lot of options to share resources or to do directly cross-device presenting.
Shared memory objects, shared semaphores, p2p mem transfers (would be slow) and the best option for doing what we would consider a truly usable 8GB (or very close to it, since there needs to have a few share resources for timing and such) would be Cross Device Presentation.

For more info, check out there doc:
https://www.amd.com/Documents/Mantle-Programming-Guide-and-API-Reference.pdf
