Both console will almost certainly be below 10 Teraflops, based on the gonzalo codenamn showing PS5 having a 1,8ghz navi gpu it will likely just have 32CU's with 2-4 disabled CU's giving 6,4-6,9TF. Xbox anaconda will probably have 40CU's but 4 disable for yield improvements so 36CU's clocked at 1,9ghz is my guess and will result in a 8,7TF gpu.

Please stop posting more nonsense every 10 minutes.

The PS4Pro already has 36CUs. There is no way a next gen chip has fewer CUs.

Also your 1.8Ghz clock is way too high for consoles, unless we get monster cooling solutions. There has been an image of a navi board floating around for a few weeks now, it has two 8-pin connectors. That alone tells you all about the problems AMD STILL has with power consumption, even at 7nm.

Unfortunately the information is pretty scarce at the moment, but according to WCCF the 64 CU limit is gone and according to a leak by KOMACHI there are 8 SEs in Navi 10, which would be very good news if true. That would mean we will see performance improvements in the geometry/rasterizer/zROP bound workloads, which becomes more prominent when scaling beyond 40 CUs (10CU/SE). Most likely the 64 ROP limit has been increased as well even though the midrange cards to be introduced in July probably won't feature more than 64 ROPs.

It will be interesting to see where the 25% IPC comes from and under what conditions they have measured it. Some will come from the improved cache and most likely widened data paths into the CUs as well as some new instructions, but it's unlikley that would yield a 25% IPC. Introducing separate integer units in the CUs similar to Turing could be one explanation but I'm sure AMD would have touted that if that was the case, so the IPC increase probably comes from several minor improvments.

All in all, at least some notable improvements from AMD, even though they still lag nVidia by quite a bit, and good news for the PS5, in particular the performance/watt improvements. Still no confirmation that Navi supports VRS, which when utilized properly can give a significant performance boost (I'm pretty sure PS5 will support it though, but that's pure speculation on my behalf). Hopefully AMD will be more informative at E3.

Finally, someone speaking English!

Navi is certainly a re-balanced uArch, the doubling of SE's over Vega is a very strong hint towards that... GCN was always very compute heavy.
It's similar to what AMD did when they took VLIW5 and made VLIW4, re-balanced the functional units for better overall utilization in games.

I think Variable Rate Shaders will be in, Microsoft is baking it into Direct X, so should be a uniform standard going forward with some luck.

Strange Brigade demo? It's a known AMD-friendly title. That's kind of shady. This sounds like GCN rebranded with some new features. Like Maxwell -> Pascal. I also wonder about the power consumption. If this is anywhere close to 200W, that's... very bad.

At least Ryzen is looking pretty good.

AMD is likely driving up the clockrates hard at the expense of power I think. I could be wrong.
But I would expect power consumption around the RX 480/580 levels, it's not super high.

vivster said:
I wonder how scalable this will be. Will it be possible to produce a higher end chip with this that's closer to the 2080? If not I see dark times for people who expect a 10+TFLOPS console.

The increase in real-world gaming performance will be substantially larger than the increase in TFLOPS.

Trumpstyle said:

I don't know the die size, Lisa Su said it was small on stage and I assume it's a midrange card putting it about 200mm2.

Anandtech has done some basic rough math and pegged it at almost 275mm2.



There will be some deviation from that of course, it's still a large die for 7nm, to put that into perspective... Vega 7 was 331mm2.

In time though, it will be an extremely cost effective chip to manufacture... But I doubt they will have a costing advantage over the 2070, which despite being 445mm2... It is built on an extremely high-yield, mature and cheap 16nm TSMC based process. AKA. 12nm.

Polaris, when it came out as the RX 480, was pretty good - just not the high-end chip everybody was hoping for, but a mid-range chip. It did keep up with Geforce 970 in performance/watt and performance in games. It just couldn't keep up with the 980/980Ti/Titan, and Pascal destroyed it in terms of performance per watt one year later.

I think your vision of Polaris got skewed by Maxwell and Pascal, where NVidia leaped so far forward that AMD couldn't nearly keep up anymore, but kept rehashing the chip as they had nothing else apart from Vega to show off.

And while 25% IPC increase is not 25% increase in performance, it should come pretty close at the same clock speed and CU amount. Also, don't forget the 50% reduction in power draw at the same time.

So yeah, it will be like Polaris, a good mid-range card that can keep up with it's peers from NVidia at it's release - it's just not the high-end card to compete with them at the top.

I never expected Polaris to hit the high-end, so my expectations were more aligned to reality back then.

The RX 480 was a good chip, don't get me wrong... And it has aged well. But a high-end part it never was... I do own a Polaris GPU, so I am talking from an owners perspective as well.

Maxwell was just a solid part and nVidia refined it with Pascal.

The reduction in power is probably what Navi needs to bring to the table the most, AMD pushed up the clocks and voltages with the RX 580 and 590, so power consumption got a little out of control...

But it was the same with Vega 64, it's actually an extremely efficient GPU... At lower clocks and lower voltages, AMD pushed it super hard to try and keep pace with nVidia.

At the end of the day though, I found it extremely difficult to recommend AMD's GPU's for gaming towards the end of Pascals life because nVidia was simply the superior option in almost every regard, even sometimes price if you shopped around.
The RTX does lean things towards AMD a little, but not definitively... And certainly not in the high-end.

Trumpstyle said:

The tweet is probably correct, those people are experts, we probably looking at a Navi card with 275mm2 die size with very close performance to geforce 2070, so it's a bit worse than I expected ):

Anandtech can still get shit wrong (And have done so in the past), but it's probably a good ballpark number.
Either way, we will know definitely in the coming months.

I will probably be an early Navi adopter, I game at 1440P, so it should be the perfect GPU for my needs.

Trumpstyle said:

Sony doesn't pay retail prices, they pay wafer costs + margins to AMD, now we know why the gonzalo codename said it was a navi 10 lite. Amd and Sony has probably done some customizations to Navi 10 to reduce the die size, they need to get it down to about 200-210mm2 to fit 8core zen2 cpu in a 350mm2 apu/soc.

Not sure what rumors you talking about, I'm assuming adoredtv, they were fake dude. He got tricked, stuff like that can happen.

About gpu prices for PC, I expect them to come down big when Nvidia launches their 7nm gpu lineup.

Rumor has it that nVidia may be updating RTX with faster GDDR6 memory rather than drop their parts to 7nm... So that may make things more difficult for AMD and will probably allow nVidia to continue to charge their nVidia tax.

fatslob-:O said:

AMD aging better is probably just down to benchmarking new games transitioning to new gfx APIs ... 

Being moderately faster tham a 2070 is easy enough when Vega 64 matched it but the hardest part for AMD is going to be finding another tier of performance so that it can get closer to the 2080 ...

That is exactly it.

AMD still has a faster Vega 7 part they can throw into the fight as well with a full 64CU part...

Guys some terrible news, I think navi sucks, look at this tweet:

It's 50% effiency gain with 7nm process and architectural improvements, just doing simple math we are absolutely not getting any crazy Teraflops numbers. The card AMD demoed is at best a 225watt gpu, probably 250watt and has about 10 Teraflops based on the 25% ipc gain. A $400 dollar console (PS5) need a gpu that pulls 120watt and a premium $500 console (Xbox anaconda) about 150-160watt.

Both console will almost certainly be below 10 Teraflops, based on the gonzalo codenamn showing PS5 having a 1,8ghz navi gpu it will likely just have 32CU's with 2-4 disabled CU's giving 6,4-6,9TF. Xbox anaconda will probably have 40CU's but 4 disable for yield improvements so 36CU's clocked at 1,9ghz is my guess and will result in a 8,7TF gpu.

Navi went from super-good to good to terrible. Look at this quote from Lisu Su at computex:

"And then, when you put that together, both the architecture – the design capability – as well as the process technology, we're seeing 1.5x or higher performance per watt capability on the new Navi products"

She mentions process technology!!!

It's not going to "suck". - It's just not going to be some revolutionary improvement that some people are making it out to be.

It's the same with Zen 2... There is a jump in IPC, but the bulk of the performance improvements is actually thanks to an uptick in clockrates thanks to the  headroom that the smaller manufacturing process brings... And then AMD takes the IPC and Clockrate and pegs it as a "50%" improvement over the old part... Which whilst true, clock for clock the needle movement was actually smaller when comparing architecture against architecture, clock for clock.

CU's and Clockrate play a role hand in hand. You can have 18 CU's and have more performance than 36 CU's.

I think about 40CU's is a good place to be with a high clockrate, 7nm does bring with it a slew of advantages in regards to die size and power consumption remember.

shikamaru317 said:

I know they don't pay retail, but a $400 at retail GPU in PS5 still seems highly unlikely to me when PS4's GPU was much cheaper than that.

I think I saw that $280-320 pricing rumor for the highest end Navi chipset on Anandtech or another big site, but I could be wrong. 

There is going to be a larger emphasis on the CPU next gen though, it's not going to be all about the GPU. Actually excited for the Playstation 5 and what it will mean in CPU based tasks and how that is going to translate over to simulation quality of the worlds being built.

So my PC will essentially be good enough for the whole next console generation.

Nice.

Specs?

Got myself an i7-9900K with an RTX 2070 and 32 Gigs of Ram. So nothing too crazy, but it should be in the ballpark of the new consoles.

That's good news though. If they have to use a crappy GPU anyways there is more room for that 1TB crazy fast SSD of yours!

AMD still has a faster Vega 7 part they can throw into the fight as well with a full 64CU part...

AMD has a lot of options relatively speaking if the rumors of 8 shader engines hold true. On 7nm EUV, they could even do with a 128 CU SKU if they wanted ... 

As for people raising an issue about the choice of game to demo Navi's performance, I don't imagine it'll factor whether it's AMD sponsored or not when just about every most likely potential AAA game benchmarks this year are coming with either DX12 or Vulkan so the playing field is somewhat skewed this year ... (RE2, Crackdown 3, Exodus, Division 2, WWZ, Rage 2, Youngblood, Eternal, Control, Detroit, Gears 5, Halo 2 remake, etc and many more that's probably yet to be revealed)

Indeed they do have allot of options, plus they have more experience with 7nm at TSMC than nVidia, so that advantage can't exactly be understated.
In saying that, Navi is still going to be a pretty average GPU all things considered... And won't be besting nVidia at 12nm (Aka 16nm Enhanced.)

8 SE's even with 64 CU's and a beefy clockrate should result in a chunky uplift though, especially backed by GDDR6 on a 256bit bus.

Finally a wise man comment, i can see a bit optimisme from your side, all this previous people has been dark, gloomy and an underestimate comment LOL. 

I believe we both want to see a powerful PS5.

I can understand the gloom though and I suspect it depends a lot on the expecations. I didn't expect Navi to be a Turing killer, AMD is/was just too far behind nVidia for that. So compared to RTX, Navi is somewhat a disappointment since it doesn't seem to beat an eight month old architecture, not even when having a process node advantage. However, compared to Vega it clearly seems to be a step forward and indicates the entire PS5 GPU will be beefed up, not just some parts of it, and combined with the performance/watt improvements it tickles my mind to see how far they will be able to push the PS5 GPU.

Unfortunately, AMD is very vague about Navi/RDNA and I suspect there are a lot of misinformation, even from usually reliable sources like AnandTech, going around. For instance, I've not found any indications that the IPC improvement is as high as 25%, which would be quite remarkable. AMD claim there is a 1.25 performance/clock improvement compared to GCN, but that's a different metric than IPC. So either the journalists at AnadTech have spoken to AMD at Computex and the IPC improvements happens to coincide with the 1.25 performance/clock improvement or their information isn't based on facts but (at least in some part) incorrect assumptions.

What is more worriesome though is that AMD don't disclose which GCN based card they have used to come up with the 1.25 performance/clock improvement. In a footnote they state it's the geometric mean for a benchmark consisting of 30 games rendered at 4K with 4xAA. If they have compared Navi to a Vega card, then a 1.25 performance/clock improvement is exceptionally good, but it's more likely they have compared it to a midrange Polaris card and then a big portion of the performance improvement simply comes from the increased bandwidth of Navi and not the RDNA architecture. Similarly they are vague about how they have measured the 1.5 performance/watt improvements. Is that compared to a Vega 14nm, Vega 7nm, Polaris 12nm or Polaris 14nm?

I believe we'll get a lot more info at E3 and until then there will probably be a lot of wild speculations, both optimistic and pessimistic.



Well, so far I'm pleased with the provided numbers. They're not great or mind blowing, but they offer a nice performance increase over AMD's current parts.

We have to remember that Navi is replacing AMD's current mid range cards, the RX 480/580/590s, that competed with Nvidia's GTX 1060. it was never meant to be a high end part. And yet we see the 5700 being compared with the RTX 2070! Even if the end product ends being with 10% of the Nvidia card in real world benchmarks, it will already be a massive improvement over what AMD has now.

And there's also an interesting question: this is the 5700 chip/card, will there be a 5800 part?

By the way, regarding power consumption, there will be two cards that will use 180 and 225W: https://wccftech.com/amd-radeon-rx-5000-navi-gpu-7nm-asrock-two-variants-report/

225W would be pretty bad. The card they've shown should have been 150W at most if they're willing to catch up with Nvidia. 180W and it's just back to the Polaris, pre-Turing status quo.
