Oh that is right, haven't thought about that.
Oh well I hope there will be versions with lower VRAM though. AMD needs to destroy Nvidia when it comes to price.

Well, looking how much concern there about with Ampere's "low" amount of RAM, AMD will be able to market their cards solely with the RAM numbers alone to win the gamers wallets.

I believe that is their strategy.
But these VRAM fearmongering people are in the vocal minority. Features like DLSS, better Raytracing, Nvidia Broadcast, CUDA, OptiX, stable drivers etc are far more important selling points than VRAM. AMD has to significantly undercut Nvidia's price in the same performance category to compete.

They don't need to match Turing, at least at the high end. They need above 2060 performance in raytracing for 40 CUs clocked at 2 GHz+. That would be less efficient than Turing, since in rasterisation we would expect 2080 Super performance. But double it up (for 80 CUs) and you get to 2080 Ti/3070 levels.
Even if you are less efficient per CU, you can still scale performance by increasing the number of CUs. And actually it's not clear that Ampere is massively more efficient in raytracing than Turing from a transistor perspective, since they increased the number of transistors by 108% vs the 2080, and performance seems to have scaled by 120%-130%.

For rdna1, the average game clocks are about 3% higher than advertised with existing 'last gen' games.
Im not sure if rdna2 6000 will have similar headroom, seeing they are already pushing 7nm with 2ghz gameclock.
My prediction is 6000/rdna2 game clocks are very much the end game limits, with no more positive upside.
I predict the opposite.
I think AIBs will be handling 2.4Ghz easy work.
+150hz shouldnt be outside the realm of possibility with a Strix level cooler, assuming the chips arent already at the power limits.

So the game clocks, aka realistically sustainable clocks in-game, are between 1.8 to 2ghz, ha!, right in between my estimates.
That 1.8ghz sure look familiar..
What happened to the 2.4ghz rumors...ha!
Shhhh!
The FUD screeching brigade will be here in no time if you keep saying that!

By amd own admission, ryzen 5000 will have even less over clocking than before. Im not optimistic

Ryzen ≠ RDNA2
It would be a big fuck you to AIBs if there is literally not even 150Mhz of headroom in these chips.
150Mhz....i dont think even OEM GPUs have failed to give atleast 150Mhz.
You really think AMDs GPUs are already at their max on AMDs coolers?
Why would any high end variant cards need to exist then?
AIBs are going to have a very very hard time charging anything above MSRP for a card thats only marginally quieter at full load and doesnt perform any better.

2.3Ghz for 80 CUs....RDNA2 can clock super high even with a huge CU count.

They will most likely use the same 2.5-3 slot coolers used in Ampere cards, as it's always the case, so the thermals shouldn't be much of an issue, my guess is it's the the power delivery/chip capabilities that will be the bottleneck.
By amd own admission, ryzen 5000 will have even less over clocking than before. Im not optimistic
But does it matter if you are getting X clocks out if the box or by manually tuning a chip yourself? IMO 2+GHz on a GPU out of the box is a much better situation than counting on silicon lottery.

I'm talking about stock operations, that's the game clock this time round, won't be higher than specs, unlike rdna1 with its +50-70mhz more headroom.
I guess AIB can go higher than game clocks specs, maybe the very best lightning/rog/Xtreme models can do about 2.15ghz.
Because 7nm is 7nm.

You mean just like most 3080 AIB cards that charge 100 bucks more while only offering like one or two percent more performance compared to the Founder Edition?

But is PS5 really like 6800 and 6900?If ps5 were to be like 6800 and 6900, at voltages normally seen with stock pc GPUs, its average sustainable frequency will be about 2ghz.

Em... you do realize that those power draw figures are not confirmed.....right? The ones quoted by the OP are simply referencing Igor's speculative numbers. Literally the same thing. Personally I doubt those power draw numbers as well based on what I've seen discussed in the tech sphere.

HBM's only real advantage over GDDR was it's lower power consumption which as history has found out, gamers don't really care about. Otherwise you would just get the same performance for a much higher price.
The only place where it's preferable nowadays are for enterprise users.

Not at all. Crysis Remake on Ultra settings @4k/unlocked FPS allocates over 16G VRAM. These newer games coming out will absolutely take advantage of the amount of VRAM on board to stabilize framerates.

Do you and me really need to have a discussion about VRAM allocation vs usage again?

You mean the CPU that just reached 6 GHz?By amd own admission, ryzen 5000 will have even less over clocking than before. Im not optimistic
AMD Ryzen 9 5950X gets record-breaking 6GHz overclock... on macOS
But it's unlikely the CPU will hit such heights for the average user

Why would I? There are likely AIB cards that will use that much power. I doubt AMD will release their own version using that much power, especially because they likely don't need to push the GPU to its absolute limit to be competitive.Can someone Ping Ascend?

The thing is, barely anyone worries about the power consumption of the nVidia cards, but now that AMD's cards are close to coming out, everyone wants to jump on the high power consumption AMD cards train.

If I have to allocate storage just because I think I might need it, I'm still locking it up. I could be doing a number of swaps within that memory block. If I had a smaller memory store, I would allocate less and probably destroy more often. It all depends but my point is that memory is a precious commodity. The more you have the better off you'll be.

That would show up in 3080 vs 3090 benchmarks. Does it?

I have never seen a benchmark tool that measures allocated VRAM space on a per-GPU basis per frame in a game. It would certainly be an interesting metric to examine.

If Crysis Remake allocates more VRAM to somehow take advantage of it to speed things up, we'd simply see a bigger gap in the 3090 vs 3080 benchmarks than than the usual 5-15%. I couldn't find any benchmarks though.

never owned an AMD gpu before but might buy the 6700xt instead of a 3060 after a month simply becuz of that vram........how r the drivers for the AMD cards?
AquaticSquirrel
Member
We won't know until they release. New launches can sometimes have driver issues, crashes or hiccups as anyone following the 3000 series launch will know. Hopefully they will have solid drivers, some whispers state that one of the reasons they have not launched these cards earlier is that they are trying to perfect the drivers, or at least remove any deal breaker issues like what happened to the 3000 series. If it is any consolation it doesn't look like they are rushing out this launch so hopefully that will translate to more stable drivers.

Drivers are fine now. They had lots of issues late last year following the 5700/XT launch but seem to have it all ironed out. ANd have been taking big strides in fixing things in timely manner. Brand wise if your not interested in Reference then AIB wise, XFX and Sapphire are in my opinion the top tier with MSI being second tier.

Well the fine wine meme does seem to be real, although I'm not sure if that is because Radeon initial drivers are maybe "just ok" and don't bring out the best in the hardware until later? Or if it is just AMD being committed to continued improvement. I think it is probably the latter.
Most of the time Nvidia cards also improve performance with drivers over time, sometimes with great gains in some edge cases but on average the gains/improvements don't seem to be as large as what AMD delivers over time vs initial launch period drivers.

Sapphire are a tier 1 AIB partner for AMD, they work exclusively with AMD. They tend to have the best overall cards for AMD in terms of quality.
Think of them as equivalent to EVGA for Nvidia.

Nice, so AMD might actually have decent graphics cards for once.
The power draw might be concerning tho, let's wait and see.

"Optimizing" For console means dropping settings 99% of the time. 9/10 "Unoptimized" PC games are just people upset that the game doesn't run well when set to Max settings which go far beyond what consoles can do.

Everyone has their own priorities in what is important to them for their purchases. Personally I think DLSS is pretty cool tech, I've no idea if AMD has anything to compete with it. Having said that currently it is only supported in around 6 titles and need to be implemented on a game by game basis by the developers. Granted that number of supported titles will likely grow over the next two years as RT starts to gain adoption due to consoles etc...
Having said that I certainly wouldn't base my purchase on an adhoc feature that needs to be supported on a game by game basis and currently only works on a tiny handful of titles. Until DLSS can be turned on at the driver level with no work from developers it is not going to be a huge thing, despite the paid promotional hype from Digital Foundry and the like.
But if DLSS is something you can't live without and you want to future proof yourself then I can't really complain, buying a 3000 series card would be a great investment for you if that is the case.

This right here is my main concern. I really, really hope they offer up a solid RT solution, but even if they do, you know they aren't going to have something like DLSS. And while it may not be for every game, DLSS is a HUGE benefit and not something I'd want to be without. AMD would seemingly have to just go for insane raw performance to try and keep up, and I don't see that happening. I hope they prove me wrong though. Either way I'm interested to see what they announce next week.

The number of games running DLSS is increasing a lot, there's tons of games that are announced to be supporting on release, or adding support for DLSS soon TM.
I expect most AAA games to support it in the future, and that's kinda all that matters, because those are the games that will be pushing these cards, I don't care if indies support it because they're usually not that demanding.

Those are fair points to be honest, can't really argue with you. The DLSS does seem like great tech. Either way I'm looking forward to seeing what AMD have in store for the reveal on the 28th.

DLSS 2.1 will be a step in the right direction. I'm convinced that Nvidia will keep pushing it and that most of the demanding games will support it, sooner than later.
