Seems that the only good card here is Vega 56. Vega 64 and Liquid are a dissaster.

But the real star will be Vega Nano. When is launch, very few cards of the same kind of Nano will stand a chance against it.

I don't know how successful Vega Nano will be simply because there isn't a lot of room for AMD to work with on price. I suppose if they only go with 4 GB of HBM2 and use chips that only have 48 function CU that would otherwise be tossed in a bin they could get away with a $300 part, but that's encroaching on 580 prices and there's a question of how much availability such a part will see.

Which variant is AMD Radeon RX Vega Nano based on? 64? Running at ~1200 MHz (estimate)?

From Anandtech's review:

On a brief aside, the number of compute engines has been an unexpectedly interesting point of discussion over the years. Back in 2013 we learned that the then-current iteration of GCN had a maximum compute engine count of 4, which AMD has stuck to ever since, including the new Vega 10. Which in turn has fostered discussions about scalability in AMD’s designs, and compute/texture-to-ROP ratios.

Talking to AMD’s engineers about the matter, they haven’t taken any steps with Vega to change this. They have made it clear that 4 compute engines is not a fundamental limitation – they know how to build a design with more engines – however to do so would require additional work. In other words, the usual engineering trade-offs apply, with AMD’s engineers focusing on addressing things like HBCC and rasterization as opposed to doing the replumbing necessary for additional compute engines in Vega 10.

So basically, RTG's engineers are claiming they could have increased the number of compute engines (and thus the number of triangles/clock) if they wanted, but they just didn't care. This reinforces my belief that they are basically giving up on gaming. If they were taking gaming seriously, they would have increased the number of compute engines to 8 and the number of ROPs to 128. They had plenty of room to do this while still fitting within the reticle limit, and it would have prevented disgraceful results like this one:



Instead, we get a card that basically retains almost all of the potential bottlenecks of Fiji. In a handful of cases, the drivers can try to use tricks to reduce the amount of geometry rendered, but when these optimizations are not done or when the geometry actually does have to be drawn, then Vega is no better than Fiji.

I don't expect anything worthwhile in gaming for Navi, either. They aren't going to bother to make two GPUs act transparently as one - they'll expect the developers to do it with explicit multi-adapter in DX12. The developers won't; instead, they will continue to write easier-to-code DX11 titles that Nvidia's driver team will optimize to the point that they are as fast as DX12. Navi will still be limited to four compute engines and 64 ROPs because RTG simply doesn't care to do any better.

Vega 56 faster than VEga 64? A lot wrong going on in that game.....

The delay, hyper focus on Zen, extreme focus on compute.. if that didn't tell you AMD's intentions, I don't know what else would. They have given up on gaming, but also failed at the GPU datacenter.

The pro-consumer market isn't large enough to sustain it, but whatever.

I think Vega could have a nice spot in the living room gaming PC with supposed Freesync TV's coming next year. Might carve out a nice little niche for itself there, expecially the nano version. the fact the new Xbox will support freesync should help spur adoption of it I hope

hmmmm, it sounds more like amd have given up on the PC gaming market because their hardware is in consoles. Consoles is where all the money is anyway and given they have released such a crap "high end" card maybe that's the way they see it?

Not that I really care. I am annoyed about waiting for vega though. When I could have bought an nvidia card months ago. Oh well yet more first world problems.

Consoles don't make much money for AMD. They initially sell at a loss for Microsoft and Sony and every time there are seasonal variations in sales, like the post-holiday season quarter, AMD's revenues take a dip.

In a way NVIDIA is much better off due to not making chips that go into consloes.

This really doesn't bode well for AMD. I really hope that the perf/w for the lower end VEGA variants aren't off the charts, especially the APUs because im quite interested in them. Ryzen has been a big hit, but VEGA is almost R600/NV30 level of bad.

It's pretty clear that Zen has been the priority, but something that is being overlooked is that both Polaris and Vega have made significant improvements in memory bandwidth efficiency. Vega does have significantly improved absolute performance vs Fiji despite having less bandwidth available. That likely bodes well for the upcoming Zen/Vega APUs, which is where the bulk of the market is, particularly in mobile.

AMD isn't being dishonest in what you posted above. Vega 64 is the fastest GPU in pure compute under $500. And it will get over 60FPS in pretty much every game out. Now saying they are fastest based on compute alone is kind of cherry picking, but getting over 60fps in those games is not dishonest. Sure it may only get 90fps to a 1080Ti's 130fps, but those extra frames mean nothing to the vast majority of people with 60Hz displays.

And since the graphic was touting 4k performance (where Vega 64 is best) those extra frames above 60fps are meaningless from a visual standpoint. I have a 4k Freesync monitor, a really nice LG, and once the game is in the Freesync band any changes in fps aren't noticeable.

The only way you can claim that Vega 64 is a 4K card is if you're talking about reducing settings a TON. In which case, a GTX 1060 is also a "4k" card.

This doesn't get me into the 4K minimums for my monitor. It would cost me $400 to have had a GTX 1080TI+Gsync monitor, but with Gsync on the monitor it would sync down to 30 offering a larger range, and the faster GPU would ensure EVERY title works.

AMD should have focused marketing on 1440p. Problem is, their GPU does best at 4K, where it doesn't actually have the grunt most 4K GPU users will want. It's the best case for those who want to stick with AMD.

Looking at reviews, it almost seems like I'm better off using a 1080Ti instead of Vega 64 even if I have Freesync. GTX 1080Ti is just so fast, especially when OC'd that it would actually just get games to 4K with a reduced setting, while Vega 64, you're just struggling to get to the 48 FPS minimum....

The 1070,1080 and 1080Ti have the same fps, so it's quite likely to be a CPU bottleneck and not geometry performance.

Now they wait for Navi..

All joking aside, would be great to see an exhaustive technological deep dive on why VEGA is the modern day R600 if not the NV30 (I still think that the NV30 was the worst out of the bunch - nothing can beat the stock cooler)

Its hard to tell if AMD (ATI) got worse over the years or if Nvidia just got way better. I honestly can't tell what happened, but here we are. I am starting to have the same feelings for AMD's GPU's as I did for their CPU's before Ryzen came along. I think AMD will need a massive jump in GPU performance to catch up, because they aren't catching up to 1080ti, which is already impossible enough. They will have to go straight from Vega performance to trying to cope with Volta. I doubt a Volta Ti card is going to play very nice with AMD next round.

- No kidding, those TPU performance summary charts are going to start looking a little ridiculous with the 1080, 1080 ti, 2060, 2070, 2080 and 2080ti sitting uncontested at the top of the pile...

I think we're past the "easy" part of making much of anything silicon related and now R&D budgets are really going to separate the wheat from the chaff. As shown earlier in this thread, NV spends ~50% more than all of AMD on GPU R&D alone. All that extra R&D money goes into ensuring they have the "next big thing" ready to rock at expected performance levels at the expected time.

No more "free lunches" from die shrinks, companies have to really work for that extra performance/power ratio and anyone that keeps chugging along like everything is the same as it was 10 or even 5 years ago is going to have a bad time...

One of the most underwhelming GPU launches in recent memory, while Fermi had power and heat issues it had no trouble dethroning the 5870, this one struggles to beat even a 1080.The asking price is also quite atrocious to be honest, frankly after doing some initial benches they should have have skipped vega entirely and go straight to Navi.

Thanks to betting everything on HBM2, they have way less wiggle room when it comes to price.

It is sad that going full HBM did not pay off at all for them.
- They dont have a speed-advantage or power-advantage in the prosumer/datacenter market. From my POV, going full HBM *could* have made sense if they got some advantage out of it. But they did not.
- The gaming market does not need HBM at all. It only makes your GPU more expensive...and cuts your margins.

I believe they should have already learned that lesson from Fury X, 980 Ti beat Fury X even with it's inferior memory technology. They should just go back to the drawing board and hire some competent gpu designers imo and completely scrap their marketing which does more harm than good to AMD.

Honestly if Navi slips at all (like Vega did) there has to be some chance of there being 3050's up there as well Although I suppose the consoles mean that AMD are at least likely to push out a decent new mid range chip like the 470/80.

You're assuming that either of those is what's holding Vega back, which we have no proof of.

Also, that Civ 6 graph is a clear example of driver overhead. It got nothing to do with GPU performance.

Don't even need to be old really, lots of low powered games released every year on steam which Vega would chew apart
