I think a reworked fiji, but not fiji. I think using fiji would be a mistake.
Ya, you are right because with their push for HDMI 2.0 and DP1.3, it would be a facepalm moment to reuse HDMI1.4a/DP1.2 Fiji in the $300-500 range next gen.
inb4 the performance per watt literally just means that nothing will change except for that TDP that will be halved.
I just hope that I'm overly pessimistic here.
Nah. Graphics card volume unit sales in 2015 are near decade low, if not near all-time low. There has to be incentive to upgrade for people using older GPUs. If someone skipped R9 200/300/Fiji series, do you think they'll suddenly be excited to buy a new GPU just to save on power? There also has to be incentive for cutting edge early adopters and that comes from more performance.
I would be fine with Fiji being shrunk, but isn't there supposed to be a new architecture for the 400 Series?
Anyways, I do want to see HBM2 make it's way from midrange and up, because it should help reduce it's cost for all those products.
True. If they have the funds to do it, it's probably best to scrap Fiji gen 1 chips entirely and redesign them to include HDMI 2.0/DP 1.3 + 3rd gen GCN architecture (AMD still considers that there were only 2 real generations of GCN not 3 like all the media talks about).
Fiji can't be reused. 4GB VRAM midrange, AFTER an 8 GB VRAM midrange is just a disaster. 6GB VRAM+ needs to be midrange. FIji isn't being reused unless AMD really doesn't care about even attempting to actually compete with Nvidia.
From a marketing point of view, if AMD goes 4GB and the competitor has 6-8GB, it could be a real disaster for them. That's why I mentioned how risky I think reusing Fury, Nano, Fury X could be. At the same time, HBM1 is limited to 4GB so to use 8GB for mid-range, they'd have to use HBM2 (too expensive) or go with GDDR5X. But going with GDDR5X requires an all new memory controller redesign for Fiji. Seems like that would get costly and complex real fast.
That's why I have no clue what they might use to fill in the $249-449 price bracket with.
Edit:
Best Bet actually would be to use new chips from the R9 390x, Fury, and Fury X. But use fiji and older chips for the cards below it. That way, your midrange higher end product can have 8GB VRAM, but the lower end midrange product can have 4GB VRAM, and be targeted at 1080p/1440p, while the other cards can handle 4K.
But 390/390X are slower than Nano/Fury/Fury X. So if you have AI flagship replacing Fury/Nano/Fury X, if you move down Fiji to the $249-449 range, suddenly you run into this 4GB limitation I am talking about.
Also I personally couldn't care less if the new 390 replacement didn't have the updated standards and used the Fiji current stuff.
Ya, but for the majority of the market they'll label it old tech. Not having HDMI 2.0 would do serious damage in 2016 and AMD is trying to push FS over HDMI unless price/performance is out of this world. Don't forget the UVD in 300 series is going to be very outdated by 2016 standards.
AMD needs the latest tech in a superior package.
I agree. They need to have upgraded UVD, HDMI 2.0, DP1.3. The old ATI/AMD was almost always leading with 2D/3D visuals/latest codec support, HD4800 brought 7.1 pass-through over HDMI, and AMD was first to adopt cutting edge DP standard, etc. They need to get back to leading on features.
If AMD Shrink Fiji, based on the 2x Perf / Watt, they could get roughly Nano performance at 75 Watts. That is low end in terms of power so they could easily have two tiers above Fiji for their mid range and high end parts. 4GB on the low end is enough but would the cost of HBM and the die size of Fiji (even shrunk) make it prohibitive?
Ya, but then you are now labeling Nano as low end, aren't you? I think that's a bit optimistic for 2016.
I have the feeling those two new GPUs Raja Koduri talked about are going for the high-end high-margin cards above the $300 mark.
That's what I am thinking one high-end, one mid-range though because otherwise how would they fill the low end $249 and below market? Reuse Tonga XT/390/390X again?
The smart move, imo, if they only plan to have 2 dies for most of 2016 is have one moderately sized one optimized for mobile, i.e. next gen Pitcairn, and one big die desktop, i.e. next gen Fiji. Make the most of Nvidia having to deliver its big die chip to HPC customers first to fulfill contracts by prioritizing desktop volume delivery over non-contractual HPC.
Wow, that's actually pretty ingenious. Didn't think of that. :thumbsup:
Using the strategy you outlined they would be able to create a lot of cut-down GPUs from both of those filling in the high-end on the desktop with cut-down big die like they have Nano/Fury/Fury X now while the Pitcairn mid-range chip would be their mid-range desktop and flagship mobile dGPU. What about the lowest end $199 and below?
IMO, if they want a 16nmFF pipe cleaner, Tonga would make a better choice. It's still GCN 1.2, and the die is almost half the size which would hopefully keep initial yields good. They would get the extra experience with the process, it'd still be a card that's probably 40% faster that a 960 but with GTX 950 power consumption. Even if the die costs are close to the same, the board costs could be lower with the reduced power consumption. That kind of performance at the <$200 price level would be very appealing, even if it doesn't hit the market until early in the new year.
Tonga seems like a disaster. Larger die than Tahiti and has 384-bit memory controller that's unused. If they are going to reuse any GPU from the old stack, might as well add HDMI 2.0/DP1.3 and shrink Hawaii. Hawaii is still a powerhouse as far as performance is concerned. 390X is about 50% faster than the 380X and their die sizes are only about 20% apart iirc (438mm2 vs. 365mm2). Aging UVD would be a sore point though.
It will be 80-100% as always with new node.
Ya, in this case also the biggest breakthrough in memory bandwidth with flagship cards hitting 800GB/sec-1TB/sec and both coming out with new/heavily revised GPU architecture. I think 80-100% @ 4K for flagship cards is realistic but they might split the gen into two halves by giving us 30-40% in 2016 and another 30-40% in 2017.
