AMD Radeon RX Vega 64 and Radeon RX Vega 56

[Marrond]

Vega 56 looks alright. But the price... meh. Also it would be nice if you used more popular titles in your gaming benchmarks. I mean I guess it's cool to know how it performs in Hitman that you will play once and forget about it but how does it fare in those games people play the living rubbishrubbishrubbishrubbish out every day? PlayerUnknown's Battlegrounds? DOTA2? Path of Exile? (personally I'd love to know how they perform in IL2 Sturmovik: Battle of Stalingrad/Moscow/Kuban but I guess it's too niche).

How about OpenCL computing performance? Who cares about synth benchmarks when you can actually download Blender with a bunch of test scenes from Blender Cloud and compare how it fares to other GPUs on the market for Cycles rendering?

LOL,why has AMD overvolted Vega56 so much:

Look at how much power was saved by undervolting Vega56 and Vega64.

[Rubarb]

main thing that puts me off is the looks, (should post a stupid emoji for that ).

if the price was right I dont care if it's not as quick as a 1080ti or what ever , I dont but top of the range anyway, it all comes down to price first/ looks second / performace per pound third.

looks is a big part of it tho and AMD have missed a barn sized door target by a mile, even 1 extra fan wouldnt have added too much to the cost, why did they go for a blower fan rather than the direct fan option is simply beyond me.

What is going on there? Am I just tired but is it that undervolting not only reduces power consumption but increases performance?

I may very well be asleep and just dreaming that.

Where AMD or Nvidia, reference cards always have blower fans so they can sell them to OEMs with poorly vented cases.
For instance:

That's probably the most expensive reference-only consumer card ever but it too clearly comes with a blower.

Apparently!!

Now why on earth would they do that if that's the case? Surely they would know this? Are we suddenly going to see better performing, less power hungry partner cards who were told about this all along?

I haven't the faintest idea what's going on anymore.

Doesn't AMD have a history of undervolting improving performance, IIRC speculation was that they push more voltage through them because of yields (higher voltage = more usable silicon).

... Am I just tired but is it that undervolting not only reduces power consumption but increases performance? ...

Same was true for Polaris - it's because an undervolted card draws less power and generates less heat, so it can maintain its peak boost clocks for longer within the same power/temperature constraints.

As to why:

... IIRC speculation was that they push more voltage through them because of yields (higher voltage = more usable silicon).

This is pretty much spot on. You use a voltage that guarantees stability across a wide range of silicon. Of course, silicon lottery means that you might get a chip that is stable at lower voltages, but we've no way of knowing how many chips could run stably at those lower voltages, or for how long, or under what conditions. It could be lots, it could just be a few. And somewhere out there there is probably a chip that can't be undervolted...

Thanks guys, yeah I do understand the logic it's just by this day and age when you know what your product can do it's disappointing that they can't mass produce so that that can be the norm rather than the exception. Damn you silicon!

Mind you I guess then that wouldn't leave room for all the buyers tinkering...

AMD makes another statement on Vega64 pricing:

http://wccftech.com/radeon-rx-vega-6...ricing-update/

Apparently certain select retailers will get rebates to keep the pricing at $499,and apparently pricing will drop towards the end of the year. This is because AMD is using Samsung HBM2(the stuff Nvidia uses in its expensive compute cards). Apparently SK Hynix has still not delivered on HBM2,and that is the original partner AMD was working with on both HBM and HBM2 - Samsung was only added much later.

Wow,if AMD had not managed to get some HBM2 from Samsung,Vega would have been delayed one year!! Wow.

At least they have finally managed to put a proper statement together.

Also wondering if part of the delay could have been additional work/testing to make sure the Samsung stuff actually worked with their design, or if its just a plug and play.

There is apparently three versions of the package which are all different:

From the technical side,I think everything went a bit tits up,so its almost they have tried to salvage what they could from a bit of a disaster with HBM2. I am actually quite shocked,SK Hynix still has not even delivered on HBM2 for AMD.
People said the Frontier Edition used Samsung HBM2 due to the capacities involved,but I certainly thought SK Hynix would be supplying it for the gaming cards.

Now I am not certain they can really compete on price,and even if they try to,I think it will only be in limited quantities and maybe not making that much money from the sales.

Edit!

At least here is the first picture of an aftermarket Vega56:

It looks like etaliers aren't the only ones pushing up the SEP for Vega.



Obviously it's only one distributor but if the companies who supply the etailers are pushing up prices all AMD's efforts are going to count for nout.

Scan and OcUK have the cheapest Vega56 at £379.99 it seems.

For now. Scan seem to have some listed twice, £90 or so more so whether that's an indicator of an initial 'batch' at the 380 i'm not sure.
