Vega 7nm early benches

Would make the efficiency pretty low doesnt crossfire get at least 80%?

Some think the software isnt reading the core speed right yet rx480 samples also gave 1000 mhz at first in early leaked benches and the perf was pretty much what it was expected to be only that it ran a bit faster once released at 1288 core.

no 60% to 80% depending on the game or benchmark and drivers is about right for a x2 crossfire card and the double memory as there is no need for 32gb on a gaming card at this time with 4k

at this point I can't believe they got 70% out of vega any other way than crossfire

with just a die shrink unless 14nm vega was so broke it should never have been released

Some more thoughts on it in there...

If its a dual gpu with dual banks of 32 GB that thing will be hella pricey for sure.

If its already running on dual gpus here seems it might be pretty seemless once it comes out in regular apps...

most likely dual banks of 16 GB AMD still calls x2 cards by total memory on card not each gpu
the UEFI data could be entered that way as 32gb card memory


......

unless it is like ryzen and two gpu's on one chip with one big pool of memory
but I think that is still a year or two out before we see that
 
They seem pretty sure about the 4096 bit 1250 mhz bw bus. That would mean 4 stacks.

But is it 1.2 tb/s per gpu or combined for both?
 
There's no point at all focusing in dual GPU/Crossfire if games don't utilize multi-gpu.

Ayup. Why sell $500 gaming cards when you can make $2500+ on enterprise boards? Only reason to push consumer Vega is to use up otherwise functional low ASIC quality silicon that can't meet enterprise voltage targets.
 
More news on the issue will be released on the 6th of June.....This Wednesday basically:


https://www.tweaktown.com/news/62105/amd-launching-vega-20-7nm-32gb-hbm2-computex-2018/index.html


7nm allows to pack up to 4X the transistor count compared to the 14nm process, so in Vega terms with it's 12.5 billion at 14nm and near 500mm^ die size, a 7nm version could have up to 50 billion for the same die size.


They do state in the above article that it's for professional markets only and it will be expensive, So Nvidia's Volta based Titan V ( 3000$ each ), may soon have some company.

:lol:

D-Day

……

Vega Frontier Edition 2

1500 to 2000 I don't think they will go near as high as Titan V

and like last time a gaming version may well follow but with 16gb

Hi there....It's been a long time since I posted indeed...:)

True, it's highly likely that a "gaming" version of this could be released with 16GB onboard to reduce costs, but despite it still being the same architecture and not Navi, the transition to the 7nm process allows options to have more hardware onboard the chip, keep the die small and use less power and do all 3 at the same time, so it might still be quite a nice refresh part.


I still won't part with my existing ones since there's still nothing stressing these out, even at 4k and still work on the double or nothing principle.....Next chips need to be twice as fast or no deal, regardless of their price as I'm limited to 2 cards since Crossfire maxes out at 2 since Vega was released....Frees up cash for each card....:lol:

Kind of a harsh way of putting it, but I suppose we could say that the power consumption issue of the original Vega is a problem and them running hot too, as well as it not taking the speed crown either as another "problem".



Already owning extensive water cooling hardware on my end, and having a power setup that was ready and able to run 4 cards with one 1200 watt PSU dedicated just for the cards, which I already owned solved the first 2 issues for me, and performance wise having 2 working together in crossfire solved the last one with speed to spare even at 4k :


So the move to 7nm alone, can solve all those 3 issues in one shot as the process uses a lot less power than the 14nm process, therefore opens possibility that it also releases less heat and allows to clock the chip faster and / or add more hardware in them while keeping the die small, and it's still the Vega architecture at the end of the day.....The current Vega is about 22 by 22 millimeters in size at 484mm^ at the 14nm process and 12.5 billion transistor budget, so a 7nm version with no changes at all hardware wise and with the same transistor budget, would be 11 by 11 millimeters ( 121mm^ die ).....It's tiny.


If however Vega 20 at 7nm is kept intentionally at the same size as it's 14nm version ( 484mm^), you can see just how much more hardware can be installed in it and still kept at the 300 watt PCI-e limit.


Gaming version?.....Who knows.
 
if a Gaming version can beat my 1080 ti strix by 20% to 40% and have hdmi 2.1 and maybe DP 1.5 I'll buy one

or two if under 600 each

looking to get a 55 to 65 inch 4k/120 freesync monitor
 
Well, well......Seems like AMD will release a 32 core threadripper tomorrow, likely featuring the same 12 nm dies of the latest Ryzen 2*** series, but as usual there's 4 dies in threadripper chips..... :D


Now let's see Vega 20 at 7 nm tomorrow as well.....Nvidia's Volta Titan V, or the Quadro version or the Tesla versions using the same chip, might be in for one hell of a shock if this Vega 20 7nm instinct card is aimed for the same market.
