AMD "Vega 20" Optical-Shrunk GPU Surfaces in Linux Patches

[btarunr]

AMD "Vega 20" is rumored to be an optical shrink of the current "Vega 10" GPU die to a newer process, either 12 nm, or 10 nm, or perhaps even 7 nm. Six new device IDs that point to "Vega 20" based products, surfaced on AMD's GPU drivers source code, with its latest commit made as recently as on 28th March. AMD "Vega 10" is a multi-chip module of a 14 nm GPU die, and two "10 nm-class" HBM2 memory stacks, sitting on a silicon interposer that facilitates high-density wiring between the three. In an effort to increase clock speeds, efficiency, or both, AMD could optically shrink the GPU die to a smaller silicon fabrication process, and carve out a new product line based on the resulting chip.

Isn't Vega 20 also going to have four stacks of HBM2 (4096-bit)?

Inbefore miners buy them all and it sells for a price of 1000€...

Not likely given the present market. It goes up and down. We are presently down.

So you think this is just temporary or will the big money move onto better things? Genuinely interested in how this plays out, also we might see the 2.4GBps HBM modules being used here.

Not at today's rates and difficulty level. It's so low right now that my friend's farm w/ 4xGTX1060s and one R9 380x only makes around $20-25/mo of profit these days. With Vega2 the ROI will be unreachable(even if it performs like crazy).

Ethash ASIC is in the works, so if Bitmain releases their miracle-box before AMD does their VEGA 20, then GPU mining becomes obsolete (at least for Ethereum and its forks). Scrypt is already overtaken by ASICs, SHA-256 is next on the line. That leaves only Equihash, but you can't keep it asic-resistant forever.

Inbefore they make up some new dumb cryptocurrency that makes graphic cards interesting again. This shit will never end.

I'm sure there's going to be a fair amount of speculators who are still going to do that.

If this does indeed happen, I wonder if the optical shrink will be AMD's GPU for this year (or next). An optical rebrand with lower power consumption and higher clocks isn't a bad thing.

 

[HD64G]

Maybe the RX570-580 successor with GDDR6 on 12nm? I cannot see why to make a 14nm--->12nm Vega 10 successor just to up the clocks 10-15% but they know better for sure. And we can relate this to the nVidia's plans for 2018, so nothing impossible.

It's a shrink, how do you expect it to have a redesigned RAM controller?

The same expectations have been thrown around about Ryzen's optical shrink. So you should have seen this one coming

More OT, if Vega manages to improve its perf/W ratio, it can become a really nice proposition. Though HBM2 will still keep it from being produced in significant quantities

The only thing that Polaris needs is to overclock much better close to 2GHz, and that's it... it will be okay for FHD.

As a reminder, TSMC "12nm" and Samsung "12nm" are just refinements of their "16nm"/"14nm" variants, not actual node shrinks, and are still just a little denser than Intel "22nm".

AMD has promised full fp64 support and availability by the "end of 2018" for Vega20…

 

[jabbadap]

Probably yes and with full fp64 compute capabilities, which means it won't be gaming gpu.

 

[MT66]

Iirc the vega 20 is on the 7nm node, thats what mark papermaster said i believe and its for machine learning. Should be sampling it toward the end of 2018. Radeon instinct vega 7nm perhaps.

Although AMD could potentially sell "broken" professional gpu's as gaming variants. Who knows?

 

[TristanX]

Seems that 'big' 7nm GPU will be Navi, while 'small'' will be old Vega ported to 7nm. AMD have no money to prepare two custom ASIC for given process.

That would make sense. On a gaming gpu that would hopefully translate to 200-250W tdp and slightly better performance (100mhz higher core clock, optimized hbm2 and less underclocking would be nice) or still 300W+ tdp and much better performance. The potential for a great gaming gpu is there, so it would be a shame if AMD left us with vega 64 and 56 for the foreseeable future. I mean, just look at hades canyon and raven ridge!

If there was a way for Polaris to scale up, we wouldn't have seen Vega.

Just because something is optically shrunk, it doesn't mean they are not allowed to revise certain parts of the chip. Good example is Ryzen refresh.

I must have missed it, what's revised in the new Ryzens?

 

[Space Lynx]

$20 says they don't provide enough stock in the first 4 months of launch, keeping us refreshing pages daily, mining aside, the last ten years alone shows how bad they are at predicting market demands for their products. sucks.

I almost regret buying my 1080 ti for $790 though, now that mining is dying, Ebay is going to be flooded in a few months with old cards. lol. oh well.

something on the memory controller if it s true that they can run up to 4000mhz ram

Old and worn out , I personally wouldn't touch them.
