AMD ships over 25,000 Radeon RX Vega graphics cards

Well, the person I responded to, whom specifically tagged me and told me to read the post, said that there is a 2-3 performance difference when there is clearly more.

 

Both you and that person has since said that there is a big difference when the memory is overclocked but so far I have seen no evidence of this. Like I said before, the only reviews I have seen struggled to overclock the card at all, and I have not seen any review compare only memory overclock vs only core overclock so I would like to see that before I buy into those arguments.

 

Not saying that the arguments are wrong, but I won't believe them without evidence. Especially not when the person who told me that is quite a bit off regarding the performance difference between power profiles.

They didn't finalize all the tests,  but GamersNexus did a couple OC/UV lives 
 

You can see the txt in various parts of the video, but there's a "final" one at 2:02:35, with earlier tests showing up in the same txt in other parts of the video (like 1:32:58)

Power target has a large impact, HBM2 too and core clock looks like it's giving a good a mount of performance uplift only with PWR up and no undervolt, so HBM2 OC+ core UV seems the best way to get Vega performance and perf/W up by quite a margin

They only tested FS though and OC at launch was a lot sketchy, while now is a little more stable, though Vega and its drivers are clearly not in an actual finalized state.

Edit:

Oh and Vega 56 memory OC limit is between 980 and 1000 Mhz, the 1000Mhz is only if you're extremely lucky and was more alluded to as possible in the Gamers Nexus video.

 

Vega64 margin should be a bit higher, since HBM is at 1.35V on 64 and FE and 1.3V on 56

I haven't watched the video yet, but from reading these posts I really don't think they prove that Vega is memory bottlenecked anywhere the same degree that was claimed earlier in the thread.

It doesn't sound to me like there is any solid evidence to determine just how much memory bottlenecked Vega is at all. For all I know (after reading these posts) it might be just as memory bottlenecked as Pascal is (which for all I know might not really be memory bottlenecked).

 

I will look at the video later, but the person who called me out made it sound like you could overclock the core 20% and get like 3-4% performance increase, while a 20% memory overclock gave a 19% performance increase.

That's the kind of evidence I would like to see.

 

I mean... the video linked isn't even about the same card. It's about Vega 56 and not Vega 64.

Oh Look Vega 56....Aaaand it's gone.

Same chip, no big difference. Maybe V64 could be even more memory bottlenecked due to larger number of shaders.

Hardwareluxx oc/uv test showed V56 performing practically the same as V64 with less than 80MHz higher gpu clock (both HBM2 at 1000 MHz)

I guess someone in AMD must have regretted using HBM2 on Vega. Expensive and limited production of this hurts this company which desperately needs more money.

HBM2 memory is the future. Everything is getting smaller not larger. Form factor alone in everything from tablets to computers will use it not gddr5. It also uses less power.

So they didnt expect selling more than 25 000 then.

Its not just 25,000. They have Ryzen, Thread Ripper, Epyc and Vega plus the 25,000. AMD has a lot going on.

I know, I am talking about Vega not other stuff.

My point, they have sold 25 000 and they are sold out everywhere...

The thing is, AMD is quite poor when compared to its main (and only) competitor in the GPU market, Nvidia. I think they should put equal priority on making money and applying new technology. HBM itself is new and potent, but it doesnt make any money at its current state. If AMD wants to develop this immature technology, then they shouldn't use it on mainstream cards, instead save it for workstation cards like the Frontier Edition or Radeon Pro Duo. Being workstation cards means they can sell them at much higher prices, balancing out the high cost on HBM.

 

I doubt if any tablet or computers without a dedicated graphics card will use GDDR5 or HBM at all. GDDR and HBM memory arent suitable as RAM.
