Topic 218130

Thoughts guys? Reviews are out.

From a gaming perspective it's pretty bad (may be fixed with drivers) but it's on par with an old 1080Ti.

Id DID perform well in the Open CL testing though. Will that have an impact on Einstein crunching?

I can't see the value in upgrading from my Vega 56's though.

VEGA VII should be really

VEGA VII should be really powerfull at einstein thanks to is 1TB/s Memory Bandwidth.

 

Looking forward to someone that purchase one and post times calculations on FGRPB1G GPU tasks.

from gaming perspective it is with undvolting more efficent as a 2080 and only 5% slower...but I would buy a custom design, because the cooling is for gaing bad. however for computing is the cooling much better.

Who did the review where thery undervolted it to 2080 power levels?

3,46 TFLOPS double precision for this price. Smile

Unfortunately, the cooling system is not good. Custom designs are not to be expected in the next weeks.

Is this the new AMD gpu for about $699 US? If so over at MilkyWay they are saying the dual precision rate is 1:4 which is much better than most gpu's lately.

There's 0 availability any

There's 0 availability any way at the moment. I think the AIB partners will hopefully do a better job of cooling this beast.

And, I reckon the price will come off over the next few weeks given the luke warm reception of this card from gamers. Just as the 2080Ti price has come down since release. The price for a 2080Ti in AUS now wildly varies from AUD$1879 (USD$1336) up to AUD$2250 (USD$1600).

If anyone wants to get some

If anyone wants to get some idea of the likely OpenCL compute performance of the new Radeon VII at Einstein (as opposed to Milkyway where double precision performance is paramount) take a look at page 11 of a very comprehensive review (performed under Linux by Phoronix).  The graphic on this page shows mean performance of a range of different compute benchmarks for a who's who list of GPUs from both AMD and NVIDIA.  It's quite an eyeopener.  In fact, the whole review is well worth reading (even though a lot of stuff is related to gaming performance).

One of the reasons I'm keen on AMD GPUs (quite apart from the 'Australia Tax' on nvidia products) is that AMD have been steadily open-sourcing all their Linux GPU drivers, over the last couple of years.  Here is a prime example of the benefits of that approach.  There are lots of very smart people out there who contribute in their spare time to driver development.  For this new release, those contributions (on top of what AMD's own people produce) have resulted in drivers of quite outstanding performance, ready to go at product launch date.  In the past, it has often been a significant time (months to years) after launch date before drivers have matured.

The new card is an updated Vega design with a die shrink from14nm to 7nm.  Its compute performance is 52% higher than the previous Vega 64.  It's up there between a 2080 and a 2080Ti.  It kills a 1080Ti.

After you finish with p11, take a look towards the bottom of p8.  You will find a system power performance graphic.  This shows it uses less power than a Vega 64, despite the 52% performance gain.  It has a pretty similar power use to a 1080Ti.  The good thing is that now the product is launched and with very interesting performance, there is bound to be a lot more open-source community interest and activity.  Over the coming months, it wouldn't surprise to see further performance gains as a result of that activity.

 

Cheers,
Gary.

Thanks for sharing that

Thanks for sharing that Gary!

I'll have a read today/tonight :)

I've got one on the way; they

I've got one on the way; they were back in stock on AMD's website today. I'll try to get it running next weekend so we can see what it can do on E@H (if it works at all).

I too have made a 'pre order'

I too have made a 'pre order' purchase but have no eta for delivery. Given the current limited UK stocking levels it could be weeks before the new toy arrives but I just had to have one!

Hopefully when your card arrives and you have it running it will not dissapoint. I look forward to hearing of your experience. On paper at least, this card should be a monster doing what we do here :-)... There is always a chance it will make for a very expensive doorstop! Given the cost of these new 'latest and greatest' cards I would rather not face the pain nVidia RTX owners are going through.
