I think crossfire is coming back.
(Sounds so stupid it might be crazy, eh?)
I mean, it kind of has to. There is not much road left for monolithic, it has to be chiplets.

My guess is that RDNA 4 was supposed to have software based crossfire for the top chips but didn't work out. So it had to be scrappedI mean, it kind of has to. There is not much road left for monolithic, it has to be chiplets.
Could be (I think there was some rumors of very late RDNA 5), but if the RDNA 4 is the RDNA 1-5700xt type of launch, short gap before the real complete stack:Considering the rumors are that RDNA 4 won't be until early 2025, that means RDNA 5 is likely 2027.

Could it no go, about that fast :

early 2025 for RDNA 4, mid 2026 for RDNA 5 ?
AMD has plans to change their gpu division name to 'Nvidia 2' but they can't get the power consumption down... at least, the prices match up.
5% faster than current top card and MSRP $2.999.69
Top Polaris was 200 dollarsI think their top part is expected to be $599, possibly $699. They want to repeat Polaris and put one in every other gaming PC.

I'm not so worried about production capacity. It's not like we're seeing shortages of anything else TSMC makes on advanced processes except for NV's datacenter AI accelerators, and those are limited by their fancy packaging facilities rather than the chip fabs. The $40k or whatever AI accelerators are a big complicated package with a bunch of chips in it. I think it's 2 compute dies, a couple others, HBM... much more complicated than a Radeon GPU or Ryzen desktop CPU. The consumer stuff isn't going to need Chip on Wafer on Substrate or whatever they call it like the AI accelerators.I meant in terms of proliferation. I think AMD has a $200 part in the works, but it might be $250 or $300. Also, money's not worth money any more, so they have to raise prices.
I fully expect Nvidia to paper launch most of their GPUs, too, then focus on workstation cards for 5x the profits.

I'm expecting cheaper options from AMD and NV this time around, partly because they have to deal with Intel Arc Battlemage chasing the low end and partly because both of them totally skipped it for the current generation. AMD made a 6500XT, 6400 and 6300 and NV made an RTX 3050, but this time around the bottom end was RX 7600 and RTX 4060 for desktops. I suspect AMD will likely have a less costly option than NV since NV doesn't seem likely to release anything that isn't fast enough to turn on ray tracing (with some help from DLSS) at 1080p, while AMD will be more realistic about it and simply admit that low end cards shouldn't be used for ray tracing.
It's all gone a bit quiet on this front...![]()
AMD announces unified UDNA GPU architecture
— bringing RDNA and CDNA together to take on Nvidia's CUDA ecosystem
Here in Berlin, Germany, at IFA 2024, AMD's Jack Huynh, the senior vice president and general manager of the Computing and Graphics Business Group, announced that the company will unify its consumer-focused RDNA and data center-focused CDNA architectures into one microarchitecture, named UDNA, that will set the stage for the company to tackle Nvidia's entrenched CUDA ecosystem more effectively.
Huynh told me (Paul Alcorn, Tom's Hardware) that CUDA has four million developers, and his goal is to pave the path for AMD to see similar success.
What precisely will UDNA change compared to the current RDNA and CDNA split? Huynh didn't go into a lot of detail, and obviously there's still plenty of groundwork to be laid. But one clear potential pain point has been the lack of dedicated AI acceleration units in RDNA. Nvidia brought tensor cores to then entire RTX line starting in 2018. AMD only has limited AI acceleration in RDNA 3, basically accessing the FP16 units in a more optimized fashion via WMMA instructions, while RDNA 2 depends purely on the GPU shaders for such work.
Our assumption is that, at some point, AMD will bring full stack support for tensor operations to its GPUs with UDNA. CDNA has had such functional units since 2020, with increased throughput and number format support being added with CDNA 2 (2021) and CDNA 3 (2023). Given the preponderance of AI work being done on both data center and client GPUs these days, adding tensor support to client GPUs seems like a critical need.

AMD's plan is built on moving a mass volume of cards and getting developers onboard. That plan also includes a moderate profit. The larger portion of the profit will come from their AI GPU solutions priced significantly less than their Nvidia equivalent. All in all the market is going to have good gaming choices in the $500 and down category. AI is here to stay, this is going to become physicX 2.0 Soon AI components are just going to be baked into every card as an offload function and compiler libraries will start supporting the calls natively. If you don't have the specific offload support there will be fallback mechanisms similar to how modern games treat older cards.Am I the only one who reads this as horrible news for gaming? I don't want AI in any form on my PC. I'm not going to be using a GPU for it. I foresee higher prices and GPU shortages again as a result of this. All of the cards get bought up for AI or Bitcoin mining again on launch.
This strategy has already failed. The "we need AMD to offer competitive parts at lower prices so Nvidia will lower prices so I can afford them" is the mentality that won out.AMD needs to stop trying to beat Nvidia performance and undercut their prices to take market share from Jenson. RT is still a novelty and doesn't increase gaming competitive advantage.
The problem for AMD is if they cut prices nvidia also will follow suit. And nv has a much larger war chest. Best for AMD to not go into direct head to head with nvidiaBut they have not really been trying to undercut nvidia though, their prices have not been not low enough to make it appealing when they have inferior features and worse efficiency and occasional drivers issues. AMD has been in effect a budget alternative (they do the same things, but a bit or a lot worse) for a long while now, but have not priced their products accordingly.
Most games have DLSS and Reflex whatnot, which are measurably and objectively superior to any similar feature AMD offers. Same goes for NVENC or overall efficiency, it's indisputable and measurable facts. It's literally a bad idea to buy an AMD GPU unless it's a massive price difference and you are sure it will pay off for your use case/lifestyle to save those bucks. I mean Christ, Space Marines 2 that came out a month ago has massive stability issues on AMD 7000 cards. That game is NEW and POPULAR, and AMD still messes it up.
Yes, there is always a few titles and use cases where AMD shines... that you can count on one hand. For the vast majority of consumers, this is a non-argument.
I don't think they can do anything other than play on pricing, they are really far behind and don't have the means to magically close that gap.
And there is 2 other problemThe problem for AMD is if they cut prices nvidia also will follow suit. And nv has a much larger war chest. Best for AMD to not go into direct head to head with nvidia
Unlike the previous plan of not moving mass volume and not get developers onboardAMD's plan is built on moving a mass volume of cards and getting developers onboard.
AMD is planning going head to head with nVidia.... but only on the 4070 and down, where they have a good chance of competing.And there is 2 other problem
1) As mentionned, underpricing is generally not enough it needs a significant price cut as Nvidia can sell less performance for the same dollar usually.
2) Nvidia card by units could be significantly cheaper to make on their end
- AIB could be accepting lesser margin for higher volume
- The very large binning of wide family product
- superior tech/drivers, deliver more fps by die size&memory bandwidth
AD104 now goes from the 7680 core 4070ti down to a variant of the 4060 using just 4352 cores and RTX 3500 desktop and mobile taht used only 5120 all along, 300mm die that is capable to sell at an high price down to just 56% of the chips enabled, that quite the business model.
AD106 you have 4608 (4070 mobile) and 3072 (66% of a small die) with the 4060 on it, all up and down the stack they are fully used with pro RTX-Mobile-Desktop version of the same product, high volume also mean amortizing the R&D over more units (that where consoles market could be really important to amd).
I.e. to be able to undercut Nvidia pricing enough, there is 2 possible things
- A technical reason for their cards to cost less to make, that what the chiplets design tried and failed, that something that could do it
- Undercutting things that Nvidia really do not want to because it would hurt the pro line, like vram amount, issue being if you need to run on a ~10gb console and 6/8gb nvidia cards because of market volume, you will not see many games that do not play well if you do not have 16/20GB of vram.
Unlike the previous plan of not moving mass volume and not get developers onboardthere could be more to the plan than the high end design did not scale as well as expected, actual reason why it would help, but it is not obvious how much better and cheaper the 6700xt would have been without a 6800-6900 card, is there a cost to the mid-range to design something that can scale higher ? Maybe, specially if that mean it must be a chiplet design, but it is never said or asked how concentrating on the mid-range will significantly help it, over the usual and always the less you do the more attention to it you can give.
And how much not having a "real" 8800xt-8900xt sku help them doing that, in what way ? Why would the 8600-8600xt-8700-8700xt need to be more expensive or worst performing if they make a 8800xt version ?AMD is planning going head to head with nVidia.... but only on the 4070 and down, where they have a good chance of competing.
Video cards have gotten stupidly expensive and it's about time the pricing is brought back down to earth. I truly hope AMD pulls this off, if only to bring a little sanity to the pricing.
The previoous method which you are endorsing was to focus on building a competitive high end die, making several cut down versions of that and making a lessor die and using that to cover the low end of the market.And how much not having a "real" 8800xt-8900xt sku help them doing that, in what way ? Why would the 8600-8600xt-8700-8700xt need to be more expensive or worst performing if they make a 8800xt version ?
People say it as if it was obvious or as if AMD did not go head-to-head and try to sell volume in the 5700xt-6700xt-7800xt and lower range all along, maybe it is, but it is not for me how significant it changes things that they do not make an extremely similar but 80 CU version of their 8700xt.
As for Dev buying in, console made that relatively working well enough I think, is FSR 2 issue, not being present in enough title ? Getting close to 200 of them and about all 2024-2025 game will have FSR 2 support. They said some PR spin, people repeat it, without asking the following why/how and by how much it help reducing the price and boosting the performance of the mid-range to not launch an actual 8800xt-8900xt, by telling us how it helped the 5700xt and was a detriment to the 6700xt-6750xt for example.
That can be overstated, $650 vs $700, in 2024 the 3080 still tie or win many benchmark (some by more than 10%):The 6800 XT clobbered the 3080 10Gb in value for money, efficiency, and longevity,
Well, that's the big issue. AMD is never the best for more than half a generation, and it's usually by 5-10%.AMD’s problem is that they can never seem to deliver a one-two punch. The 6800 XT clobbered the 3080 10Gb in value for money, efficiency, and longevity, but the 7900 series was a big disappointment and 8900 is a no-show. They shouldn’t have put all of their eggs in the MCM basket. Assuming they work the bugs out, you can extrapolate some very impressive performance numbers from top RDNA 5 based on the midrange RDNA 4’s performance expectations of being somewhere near a 4070 Ti Super. But RDNA 5 is not going to come out soon enough to help consumer choice and pricing for at least another year.
It was never $650 vs $700, though. For a long time it was $1,000 to $1,300 for 6800 XT vs up to $2,000 for 3080. When prices came back down to Earth, the 6800 XT hit its MSRP much sooner. The 3080 wasn’t widely available at MSRP until the generation was on its way out. Even if the pandemic craze pricing had never happened, shipments showed that the $700 was only intended to be a phantom price to trick reviewers, available only on low-volume FE and reference cards that would be constantly out of stock, and the real price was more like $800.That can be overstated, $650 vs $700, in 2024 the 3080 still tie or win many benchmark (some by more than 10%):

average in a recent 2024 test suite:
It was a winner, but not by some clobbering amount and DLSS could end up making it close to some.
And with 2024 drivers:
https://www.techpowerup.com/review/nvidia-geforce-rtx-4080-super-founders-edition/41.html
40 watt difference, 50 for max, for the model they had 3080 easier for 20ms spiking than the 6800xt, a win but not really clobbering.
Nicehash create stange price, they ended up probably similar value for money if you ran it enough hours a day here (i imagine that what was setting those relative price)It was never $650 vs $700, though. For a long time it was $1,000 to $1,300 for 6800 XT vs up to $2,000 for 3080.
Balanced by games that do not have an raytracing off option, consoles and the popularity of 10gb or less GPU kind of force the hand of gamedev to make playable game with 10 or less gb. Are people playing Blackmyth (a record breaker seller) feel like the 3080 has less longevity than the 6800xt, it is a mixed bag.You might see similar average FPS in bechmarks, but the 10 GB card is going to have a lot more stutters as time goes on.
Are people playing BMW with Hard RT on on a 3080 ?Are people playing Blackmyth (a record breaker seller) feel like the 3080 has less longevity than the 6800xt
Obviously not, at lower setting than that, but it is still an example at playable setting where the 3080 did not age worst than a 6800xt.Are people playing BMW with Hard RT on on a 3080 ?
At what settings ??
You make a good case that “clobbered” was too strong of a word. But whatever word I should have chosen, that’s what I’d like to see AMD bring to the table with Navi 5 in 2026.
With the actual street price, for a gamer never running nicehash that was probably a correct word, I had more the $50 price gap in mind, it is just something I often see everywhere about the 2 cards, and yet it seem that half the big game released 4 years later run better on the 3080...You make a good case that “clobbered” was too strong of a word.

Now he says this is 192 bit bus & not the 384 bit bus
Apologies for over hyping this
Still lots to be excited
The PS5 pro was identical to 9060 xt in performance
Whereas this new xbox GPU will literally be the 9070 xt successor
that is still quite a leap in performance over the PS5 pro (if the power budgets allow this)
View: https://youtube.com/watch?v=uLsykckkoZU
If the new xbox has the 9070 xt successor in it, what will the system cost at launch 999? I feel like they need another generation like the Xbox One and PS 4 where they pull back on the specs a bit, things are way too expensive right now and I'm not so sure it's wise to sell at console at a huge loss.Next gen 9070 xt successor could have 36 wgp or 72 cu
https://x.com/Kepler_L2/status/1946289792657793093
Could AMD simply attach a MID (Media Interface Die) with Display/Media Engine and PCIe to the Magnus GCD and turn that into a desktop GPU?
Latest should be the latest to make per unit at the same level of wanted performance ? RDNA 5 or newer depending on launch date make a lot of sense.If the new xbox has the 9070 xt successor in it, what will the system cost at launch 999?
