UPDATED* AMD announces the Radeon VII - but it's $699 | Nvidia calls it "Lousy"

It was good to see that for Radeon 7 gaming the performance increase over Vega 64 is a lot higher than the clock-speed increase. Seems to be a combo of clocks, memory bandwidth and some micro-architectural tweaks.

 

I'm guessing the original Vega was a bit immature with all the stories about the project been short staffed and rushed because of engineering resources diverted to Navi. When Vega64 came out there was some tests done with it downclocked to Fury X clocks which proved that clock for clock the improvement was less than 5% over Fiji.

I don't think there's any architectural tweaks that would aid gaming. As far as I know it's all compute and ML. Of course there might be silicon bug fixes but I haven't heard of anything being gaming oriented specifically. I mean it is MI50 leftovers after all. Vega is mostly a write-off for consumers. Great enterprise card though.

Anandtech just confirmed that there's not 128 ROPs on the chip after all. That's disappointing. However that explains the small performance gain and somehow becomes somewhat of a relief. So the gains are all memory bandwidth and clock speed.

rip ROPs 😰

Ok, so there aren't 128 ROPs. But how many are there? Still 64 or have they bumped that to 96 ? I mean, if they gained all this performance from 200MHz more on the core and some bandwidth on HBM2, then that's quite significant, meaning Vega core is actually really capable, if you can get it clocked high enough and give it enough memory bandwidth. If Radeon 7 had 2GHz core like RTX 2080 (or Ti), it would be in the same performance territory.

It's interesting they cut out 4 CU's (Vega 64 had 64 of them, Radeon 7 has 60) while obtaining higher performance just from clocks then if ROP count is the same as on Vega 64.

Nothing's changed in Vega in the uarch so it's still 64. You have to overclock the Nvidia cards to get 2 GHz. You won't get it out of the box from what I can tell.

All of a sudden I'm interested in the card at all... I was assuming the FP64 would be crippled like consumer cards are these days. If not, this is HUGE for compute. The bandwidth starts to make sense. Think this would be by far the fastest FP64 card under 4 figure price tag.

Well, ya it's still "Vega (GCN 5)" and 64 ROPs.  The boost clock is 1800, but no word on base/stock.  But, the manufacturing process is 7nms compared to the 14nm of Vega 64.

My GTX 1080Ti runs at 1950MHz out of the box (granted, it's AORUS which isn't reference). With some convincing, I think they could ship it at 2GHz out of the box. But still, 50MHz probably doesn't make much of a difference.

Aren't the listed specs just for the ref model?  If so I'm sure XFX or Sapphire could have a higher clocked card.

That's the highest factory overclock I've seen yet. Most seem to be in the 1840-1900 range. Yours is probably the most expensive card in the lineup considering I looked at a Gigabyte card that was clocked much lower.

 

Edit: just saw yours is a Pascal card. From what I can tell Turing cards on average are clocked lower from the factory I think. Probably to keep the power in check. The uarch requires more power.

RTX cards have more shaders so they need to compensate that with lower clocks. Besides, this 1080Ti isn't even the fastest, there's Xtreme version of it, but it was too expensive and imo not worth it. Happy with this one tho. Good cooler unlike Strix GTX 980 I had before that had really noisy fans that often rumbled in a really weird way.

Ya the clocks are like 15% higher but the performance is like 30% faster. Apart from the memory bandwidth maybe there was a little tweaking to get rid of some architectural bugs or inefficiencies. 

 

It's possible that this is the vega architecture we should have gotten at first, and the stories about Engineers being diverted to Navi resulting in the original Vega being sub par and undercooked were true. 

 

We should get a better idea in 3 weeks when they are sending out the samples to reviewers they will brief them on all the changes and optimizations done if any.

By a hell of a lot too, near 100 times faster.

Looking only at rated flops, assuming it is near enough same as MI50, it is 16x faster than 2080 Ti, 21x faster than 2080. 8.5x faster than Vega64. Assumes scaling only with rated flops and doesn't take ram bandwidth into consideration.

We'll never get the Vega we were promised. Vega responds very well to memory bandwidth. I'm pretty sure the remaining 10-15% is all memory.

I have wanted as Vega 64 since launch. Just never got one. I am super tempted to get this just so I dont have to give Nvidia the $700 again. I already had 1 1080 and 2 1070s...  My next build will be all AMD later this year.

Ya we will have to wait for reviews but tbh for now this new Radeon 7 looks more appealing to me than Vega64 did. This seems like a more balanced design. Whereas Vega 64 was starved for memory bandwidth so it performed how a hypothetical Fury X would if you could somehow clock it that high. Also with Radeon 7 for once people can buy the reference air cooler as it actually is good.

ARGH! Those External IF links were worth at least a few good videos among the TechTuber set. Someone was going to get 2 working together. I'm bummed about that. I guess we'll have to wait for the 2x GPU Instinct cards later in the year. (IF exposed over PCIe 4.0 means they can actually just toss 2 Compute GPUs the same PCB and they'll act as 1 GPU.)

I'm betting on the FP64 being enabled. If it is then I will be buying this for my simulation programming. These are the numbers on GPU db. This is good news for AMD who haven't had a decent FP64 card since 2013. Better FP32 than the 2080 Ti as well. Better FP64 than all but Volta and Quadro 8000

 

In OpenCL work we already know from AMDs numbers that this card easily beats out the 2080 Ti.

AMD's benchmark number are in the footnote here. They show:

Quote

Testing done by AMD performance labs 1/3/19 on AMD Ryzen 2700X,16GB DDR4 3000MHz, Radeon VII, Radeon RX Vega 64, AMD Driver 18.50 and Windows 10. Across 4 content creation workloads/benchmarks: Davinci Resolve 15, Adobe Premiere, LuxMark and Blender. Radeon VII completed in /scored 101s, 330s, 50202 and 92s respectively. Radeon RX Vega 64 completed in/scored 138s, 462s, 31013 and 126s respectively. Resulting in Radeon VII vs Radeon RX 64 performance uplift of: 1.27x, 1.29x, 1.62x and 1.27x respectively.

We can see on this site and here that a score of 50202 is the same or better than the 2080 Ti and is only beaten by Volta GPUs.

Looking good for compute!
