Oh. OH. Being foreign does have it's drawbacks when trying to understand such things. Thanks for the clarification!
 


And it seems you're not from a Spanish speaking country either, since "dedos de mantequilla" is the direct translation to it and implies the same.

But yeah, let's go back to speculation with that out of the way, haha.

Cheers! 😛
 


If those are legit that is very promising! Matching the 980 and Fury isn't bad, especially at stock speed.
 
It's not quite at Fury levels, but it's at 980 levels at least (check the detailed report). Also, another thing to point out, it's using GDDR5/X at 2Ghz (since HBM wouldn't be clocked that high) and it's the 8GB version. I wonder if it's GDDR5 or GDDR5X. From the performance standpoint, it might be GDDR5.

Cheers!
 
Yeah, Nvidia is using GDDR5 at 8 GT/s and GDDR5X at 10 GT/s, so this is likely GDDR5.

Not that it really matters much beyond the clocks. GDDR5X is very closely related to GDDR5, HBM is where things get radically different.
 


I'm guessing that test is being boosted by something new in the uArch, assuming the results are genuine of course. Maybe that's a very geometry heavy scene and the new primitive discard accelerator is kicking in? Thinking about it that new block could likely solve AMD's relative weakness in tessellation heavy scenarios- as I'd imagine much of the tessellation is hidden anyway once it goes above a certain point.
 


Well I think it's possible there will be a more powerful version of the 480, as Polaris 10 having 36 cu's sounds strange. You would think the full die would be bigger. I guess we'll find out more on the 29th.
 


That and all three have a Core i7 4770K listed but each have different clock speed or turbo speeds listed. Makes me wonder why.
 


The two first are with a 4770, the last is with a 4770K. They have slightly different clocks.

I don't think it'll really affect the benchmark aside from the Physics test, but obviously it's not a perfect comparison.
 
here is an article from forbes from amd http://www.forbes.com/sites/jasonevangelho/2016/06/12/exclusive-amds-radeon-uprising-campaign-incites-gpu-rebellion/#7547af811c8d

interesting note is they speak of handing a lot more control of voltages and other things to the buyer of the card. handing a lot more overclocking potential and control to the user. unlike nvidia which has clearly locked down the new pascal cards in this respect. would be a nice salvo fired at nvidia by amd if they allow such control while nvidia does not.
 


nVidia has learned it's "lesson" about giving too much control over to users. Back in the day of "unlimited" warranties with some AiB's, nVidia was seeing lots of damaged GPU's. I think nVidia was put under pressure from their AiB partners to lock down some of the overclocking. It is now up to the AiB's to free up some of the "restrictions" with custom cards and custom BIOS's on said cards.

Opening up overclocking on this generation of AMD's GPU's may actually be practical now. Before this release (on this process) AMD really didn't have the thermal headroom for much overclocking as their GPU's were already running very hot. I expect this new process to allow AMD GPU's to overclock quite nicely. It's nice to see AMD trending in this direction. The 300 series was an improvement (albeit small) over the 200 series GPU's which were practically nuclear. The step from the 300 series to the 400 series should be dramatic. However we will need to wait and see if they release a more "flagship" product like a 490/X to see if these improvements translate to a larger die in a significant way.
 


OMG, the comments are bad... It's like the full of worst from Twitch went to that thing, lol.

Still, I'm LMAO with the comments. Specially the: "1FPS, console port junk" XD

Cheers!

EDIT: Ok, so the 480, 470 and 460 are very ready and will be available the 29th. The interesting bit was a quote from the DOOM head lead, but I don't want to take it at face value: "you won't need a 700 dollar video card to play DOOM". That was a very nice jab at nVidia, haha.

No signs of Zen performance numbers, but they did say a lot of pretty marketing terms that we don't really care about.
 
Cheers for the link Math, interesting they said the entire Polaris range was 460,470 & 480 so maybe 390 will be Vega or they mean't the entire range thats confirmed but I would think any card more powerful than 480 would at least get a mention if it was coming any time soon.
 


Shots fired, for sure.

Too bad they're doing this while Belgium and Italy are playing.
