AMD Vega 10, Vega 11, Vega 12 and Vega 20 Rumors and Discussion

You seriously think they're concealing information this late in the game? Come on...

 

You have some solid benchmarks of Vega and architectural details to show me?

 

Of course not, don't be facetious, you know exactly what I mean.

Do you seriously believe they are withholding information so as to not give away how it competes with *Volta*?

Maybe that was sarcasm that went over my head?

 

One plausible explanation would be drivers, maybe they are not up to par yet. The consumer cards are 2 months away from release and probably 3 months away from stock being healthy.

 

Well the feature set is more in line with Voltage than Pascal, so why not? Unified memory, theoretical TFLOPs, FP16 (possibly), so why not? All indications were they skipped high end Polaris to focus on high end Vega against Volta which was pushed back when HMC fell through.

 

Absolutely, but that's a far cry from claiming they're withholding information so as to not give away how it compares to *volta*, because it outperforming anything Pascal based is a given.

The point being that the reason they are not showing more straightforward performance numbers is because they are not impressive, and not that they are so impressive that they don't want to give nvidia a heads up, that seems like very wishful thinking .

12.5 tflops is comfortably Pascal territory, a 1080Ti is around 14 tflops if you consider the aftermarket models that throttle far less.

The Volta based GP102 equivalent will likely be in the 16tflop range.

Unified memory is also available on Pascal ?

Like I said, seems like wishful thinking.

 

It really doesn't matter what they demoed if the card is 2 months away still. What else are they going to show? They already showed a single card demo multiple times.

Also nobody has ever done a GPU demo with an fps counter for a card that is 2 months from release, why does anyone expect AMD to start now?

 

That may be part of it, but then why is the NCU configuration still unknown? That would be useful for any programmers designing for the hardware. If AMD wanted the server market, providing simple details would be a good idea to get people started.

Yet it's faster than P100 at some tasks and TFLOPs can be misleading without knowing the NCU configuration.

Not the hardware form like what Volta advertised. There is a difference and I don't foresee Pascal paging data like the HBCC should enable. Still a question if the controller can work on x86.

If you want to talk Volta, take it to another thread, but my point stands. I'm sure driver work is part of the reason, all indications are that Vega targets Volta.

 

Nobody, except AMD who has already done 2 such demos of Vega...

 

The didn't put settings in those demos so the fps is worthless. So it's either FPS or settings, not both.

 

I never said that AMD pre-pre-pre-pre-launches were not worthless.

 

When was it stated there was a high-end polaris? I thought it was playing out exactly like that chart with polaris, vega, and navi suggested. Lower end in polaris and high end in vega.

 

Pascal has hardware page migration that works on x86 and Power: https://devblogs.nvidia.com/parallelforall/beyond-gpu-memory-limits-unified-memory-pascal/

 

Really? So now Vega will somehow leapfrog Pascal and achieve 100% performance over Fiji with what? The same ALU count and a frequency boost?

These kind of statements are dangerous, this just keeps repeating every time AMD is about to launch something. People kept believing Polaris is targetting GTX 1080 till the very last minute, also with Fiji before it and Hawaii too. The hype kept reaching unbelievable levels, till it came crashing down. If AMD had a winner on their hands they wouldn't hesitate to show it in a heartbeat. Afterall, their premium card is only a month away.

 

This is from Nvidia Volta white paper:

IOW: improved virtual memory access, but not the first to have HW support virtual memory.

I don't understand the urge to pit Vega against this architecture but not the other. At the end of the day, what matters is that AMD took a break from competing against the high end for more than a year.
But one has to give credit to AMD marketing for realizing that putting "Poor Pasca..." in that video would have made them look even dumber.

 

They did, they told the press they ran both the Doom and Battlefront demos at the Ultra settings.

 

No they didn't...

Yes, they did...

This is all besides the point, they HAVE run demos with settings+performance numbers before. Surely you can't have forgotten this

 

hmm, I guess they did show the doom one but I know they did not have settings for the sniper elite demo they did.

The chart for the AotS is from a launch event tho...
