If you didn't think two 230mm2 chips could compete with 1 315mm2 chip then you had some seriously low, low expectations. Pitcairn in crossfire soundly best GK104. These leaks show Polaris 10 essentially matching GP104. From a technical perspective, it's an actuality that AMD will have lost significant ground in perf/mm2. The only thing this is proving to me is how much Nvidia's prices suck right now.

Who cares what size the die is? Nvidia is currently charging $450 for their cut down version and AMD will sell you one for $199. CF 480's will murder 1070.

Anyways that 1.5ghz claim is awesome.. nearly a 50% overclock from base!!!
 
It seems like Nvidia wants to get away from it. We will have to see if AMD is willing, or if devs want to spend the time on it. I would imagine devs really dont want to though.
It all points to Nvidia being behind on the transition to scalable multi-die GPU families. AMD needs the ground work done by 2018 to ensure a worthwhile experience. Nvidia, if limited to monolithic dies, would prefer little to no work done on multi GPU, as scalable many die GPUs on interposers can scale beyond the monolithic die limit. They can't say no more SLI as this would alienate their most performance oriented and lucrative fans. The first step has been to say max 2 card SLI from this point. If any of the new consoles have multiple GPUs then we'll see what happens.

As I said in a post several weeks ago, I think multi-GPU is going to experience a huge renaissance. The future as envisioned and stated by Koduri and AMD. They seem to be betting on and making it happen.

The only way SLI/CF will take off if AMD somehow manages to convince console makers to put dual GPUs in their system. AMD would have to make an offer those console makers can't refuse. If that happens, developers would freakin' hate it but will be forced to use it. Highly doubt that would happen, though.

I'm pretty sure this is the plan as AMD higher-ups have hinted at it a few times...smaller chips being used in multiples is where the industry will head over the next decade.

My build next month will be using 2 480s or 3 470s depending on AIB performance and price. Super excited since I'm coming from my first major mining/gaming rig (965be/dual 7950s)

With DX12 multi-gpu is going to be much more impressive than it was on DX11 and prior.

I think the chances of that happening are minimal. 2 GPU's are bound to being more power inefficient and there is twice the chance of GPU failure. Also people who buy consoles generally don't take care of them at all (i.e clean out dust) exacerbating the problem.

The only way I can see it happening is if AMD puts 2 GPU's on on a single die, but I'm not sure this is even technically possible.

Actually that's a 16% overclock if we look at XFX's 1288 MHz clockspeed.

CF 480's will murder 1070.

Yet most people will still pay more for the fast single GPU VGA. Even if you look at AMD, I'd rather take a heavily OCed Radeon RX 480 than Radeon RX 460/470 Crossfire. Multi GPU support has been poor in some of the latest titles.

Some custom Geforce(s) GTX 1070 can come really close to Geforce GTX 1080 FE (stock). If we look at the latest 3DMark chart from Videocardz, 2x 232mm² P10 XT is not really murdering 3/4 of a 314mm² GP104 - 92% the score @ Fire Strike Ultra (4598 vs 4990 pts).

The 3dmark of videocardz is not really that reliable right?
That would imply that 480 is ~10% faster than 470. That would imply 470 would have 2048 shaders (at least). Which doesn't fit with the released benchmarks of AMD of 270x versus 470. (which actually fits better with the rumour of 1792 shaders).


Also your links to the 460 imply the same right?

if 460 = 50% of 470 with lower clocks. (1GHz)-->7900 * 2 * 1.2 ~ 19000.

470 should be close to 290 performance (>+60% on top of 270x):
Scaling should be extremely bad for the 470 to get ~13000.

However 7900 * 1.75 * 1.2 = 16600 would be more in line with its expected performance of around 13000 in this benchmark.

Which would put the expected score of an 480 to around 16900 or in line with Fury. (which falls in line with other rumours)
_________________

in short, the leak of 460 in combination with released information from AMD about 470 vs 270x would invalidate the videocardz benchmarks imho.

When CF/mGPU works, sometimes up to 6 months after release. I really hope DX12 ends up meaning better mGPU support, not worse, but I fear that mGPU is headed on a downward trajectory for at least the next year or so.

Shouldn't VR be the simplest workload for CF to fly. 1 card for 1 eye. 😵

Double edit, just need to get the programming done right.

That's effin daylight robbery D:

I prefer Amazon though; this will likely be the launch price for many parts of the world outside US, prepare to get robbed by (r)etailers 😀
I wouldn't be surprised when they release here in two weeks that the "MSRP" price of $199 wont be the actual price just like the 1070 $379 price wasnt the real price either.

Yes, there will be a Founders Edition RX 480 with the best craftsmanship and premium materials for $100 more than the $199 MSRP.

MultiGPU AFR style doesn't work well with anything that introduces dependencies between frames like TAA. Most modern engines use TAA as primary anti-aliasing method..so drawn your own conclusions 🙂 For multi GPU to really work we need such configurations to *efficiently* behave as a single GPU, which is not impossible but it's damn hard.

And a GTX 1070 murders a single RX 480 by the tune of 45-50%. CFX and SLI aren't practical solutions. Scaling is game and developer dependent, as well as driver dependent. P10 is just looking more and more meh. The only way P10 is a great deal is if it comes in at $229 or less and the 1070 stays inflated. If the 1070 comes down to MSRP or the 8gb 480's are $249 out of the gate, then it's only a very small increase in perf/$ over $400 1070's which is right in line with how lower performing parts should be priced.

The 8gb models should be $229 to $249. The 1070 won't go down in price just yet. I expect them to perform pretty close even if it's not crossfire. At least for 1080p.

What are you basing this on? I have definitely seen and bought AMD MSRP reference cards at MSRP before on the day of the launch. The same way people have bought $699 1080 FE cards.

If a company says that's the price for their reference card than that's the price, unless the supply is so low, then the retailers start gouging.

Maybe it won't happen with amd but with nvidia that's the case. Early adopters usually pay a premium. Let's hope supply is good enough.

could also be 15-25%... if you believe other leaks and not videocardz leak.

Yeah, but then you have to deal with lack of driver support and other issues associated with multiple cards. Not a huge problem if you're not a day-one gamer, but both CF and SLI support has seemed to be especially bad right now. Maybe it's a consequence of both AMD and NV shifting focus to new cards, but I don't know if I'd want to run CF right now even if the value is there just because of the poor support as of late.

Tell me how you're able to state all these claims without seeing a single review? Leaked synthetic benchmarks don't really mean much. A lot of indicators out there that this may be a great OC'ing chip. I'll be damned if I had to read through thread after thread of people saying its not fair to compare a FuryX with a 980ti when the 980ti overclocks so well and then hear everyone go back to "stock vs stock" testing.

Personally, I'd prefer "lower" pure FPS scaling in return for better and more consistent frametimes a-la Civ BE's SFR implementation. If you have explicit control over the GPU and you don't pick an AFR based method you could (theoretically) reuse data over frames for things like TAA while still getting meaningful scaling. Perhaps you could do even a "Smart AFR" that is somewhere in between, but that's beyond my understanding. At the end of the day though, im all for an improved experience even if the pure FPS scaling is not as high in the microstutter filled world of driver-based AFR. I'd buy a second card that got only 50% average FPS scaling if it stuttered less and dropped fewer frames, felt smoother, etc.

Well, here are the news for you. DX12 Explicit multiadapter Linked mode, the basis of the next gen consoles and AMDs future nextgen multigpu dies on interposer GPUs.
