videocardzAMD Radeon R9 290X confirmed to feature 64 ROPs

[BallaTheFeared]

I think the difference would be how far they went on TDP, and if they continued this locked down shenanigans that required bios mods to unfluck.

Should be interesting to see how much better perf/w they get out of 290X, and what the final draw is because if it's 200/210 like Titan/780 and faster Nvidia will be between a rock and a hard place with just a simple SMX tacked on.

Still just tossing thoughts out, nothing concerete we don't know anything of importance yet, performance, wattage, perf/w, OC headroom, boost characteristics...

so there you have it. 438 sq mm Hawaii. a tour de force of the AMD GCN architecture. 6.2 billion transistors. 512 bit memory bus, 64 ROPs. 4 billion triangles/sec, 64 Gigapixels/s fill rate, 176 Gigatexels / sec.

mind boggling is the word to describe this GPU. it will crush Tahiti on perf/watt, perf/sq mm. i remember sushiwarrior saying it beats Pitcairn too in both metrics.

Nvidia's response is to observe the competition's perf and pricing and adjust their pricing accordingly. Nvidia have a full GK110 Geforce to bring. But it looks more likely that Nvidia is going to need that. Nvidia is in for a long winter. With BF4, Mantle and R9 290X and the next gen consoles this holiday season "RADEON IS GAMING" truly makes sense. :thumbsup:

also credit to sushi for trying to reveal as much as possible about Hawaii without hurting his contact. he was right on all counts.

Hmm. This will drive 3 x 1080p in current gen then? Looks like a big bump over 7970....

I'm out after this, people are taking perceived slights towards companies personally and that never ends well.

Here is the comment that sparked the response.



My reply:




Anything I said there wrong, anything I said there have anything to do with 1500MHz 7970s? Anything said there have anything to do with performance today? Performance in BF4? Anyone have any idea 1125 was a below average OC for a 7970 on January 9th? Anything at all with what I said that gave the impression that 7970 wasn't way faster than the 580, OC or not? Anything I said in there that made it seem like the 7970 wasn't much faster than the 580 OC vs OC then or now?

Anything at all, to warrant what has been said since?


I also said I would take back what I said about the ROPs and BUS until we see it in reviews and we have more information, but that was of course ignored much like the comment I made was ignored and a new one was spun up for straw man attacks.

Notice I said 580, implying STOCK, which was my complaint because when HD 7970 launched OCing it and comparing to a stock 580 was taboo but these same people had no issues comparing an OC'ed 460 to a stock 6870 (in fact this is my third time stating this, my initial was in my first post which you quoted and responded to something I didn't say.)

I didn't understand why you replied to me with OC'ed 580's since that wasn't part of my post at any point. Explains why you called my post a half truth. My post has nothing to do with the tanget you guys are arguing.

 

[NTMBK]

Why Ugh? Price?

Probably the rampant fanboyism from raghu78.

 

[Grooveriding]

The 290/290X are going to be pleasantly less expensive than the 780 and Titan.

I'm thinking nvidia will have to drop prices, maybe not right away, but once these cards gain momentum because of their price and performance against the 780/Titan, they likely will.

Maybe they will do a full GK110, but with all their harping on efficiency and power consumption, I have my doubts they would do a stock card with a higher TDP.

From what we've seen with cards like the 780 Classified that allow you to modify voltage and get clocks to the point where you are decently beyond stock Titan performance; you're no longer anywhere near efficient - cards are then consuming almost 400W and running at 90C under air cooling. Makes more sense to release a Titan core with 3GB RAM as 775 and full GK110 as 785 with the same TDP if they are actually going to want to regain the performance crown before 20nm.

SushiWarrior :thumbsup:

yeah big :thumbsup: to sushi. actually coming to think of it HD 7870 doubles everything of HD 7770 (sp, geometry engines, raster engines, TMU, ROPs, memory bus width and bandwidth) and ends up around 1.9x perf of HD 7770.

R9 290 is actually HD 7870 doubled up all over once again. sp, geometry engines, raster engines, TMU, ROPs, memory bus width and bandwidth are all doubled. ACE count is quadrupled from 2 to 8. I would not be surprised if we see a similar 1.9x perf of HD 7870. In that case R9 290 beats a GTX 780 and ends up close to Titan. now that we see the specs, R9 290X performing at 2x the HD 7870 would not surprise me.

 

[Nintendesert]

Am I mistaken or is a full GK110 Tesla?


Unless Tesla buyers are drying up I'm not sure how much financially Nvidia has to gain by selling expensive chips at cheaper consumer price points. That's what made Titan so amazing for Nvidia, binned chips not worthy of being a Tesla commanded a huge premium in the consumer market.

Unless Nvidia feels that money be.. darned.. that holding the performance crown is worth those lost sales.

I'd figure it would still have the $1,000 price point (or more) and at that point, they aren't losing much. Selling a couple hundred $1,000 cards beats selling a few dozen $3,500 cards.

 

[BallaTheFeared]

Nvidia is dual purpose with all their chips afaik, I dunno about GK107/8/9 47 82 or any of the other variants, but both GK104 and GK110 are HPC cards as well as geforce.

I don't know their sales numbers on Tesla vs. GeForce if both using a GK110 chip, so I have no idea how that works out for them.

That we're even talking about AMD close to Titan performance is a great turn of events this generation. I was starting to think that Titan was it for 28nm.

 

[exar333]

I think the specs look great, and I am glad I waited on the 780 to see how this compared. It look's like I will probably go with the 290 if benches are in-line with what we are expecting from the specs...

My only concern are the 280x review(s) and the relatively poor overclocking potential there. If the 290 doesn't OC very well, then the 20-30% advantage over the 7970 is pretty much erased because those were VERY good overclockers. If the 290/290x DOES OC well (15-20%+) then we are looking at an amazing card.

I don't think we will really know until we start seeing a representative sampling of the OC headroom on different models. If good performance and OC ability is confirmed, I am in for 1 (or 2).

 

[blackened23]

Erm, the impression I get is that the 280X overclocks just fine. The original clock of the 7970 was 925MHz. If you look at various Asus DC2 and Gigabyte WF3 280X reviews, most of them are overclocking in the 1200mhz+ range. That's a huge jump over the original speed of 925MHz and a fairly large overclock IMO.

You also were pretty damn close on your prediction of a larger die you predicted back in June (420-440sq mm) along with the possible performance improvement %, so I have to give you also a :thumbsup:

Many of the reviews I read were 1200+ overclocks, while there were also reviews in the mid 11XX range.

I would be surprised if it's (280x) any different than current Tahiti chips.

That's an average of 1072 CORE and 1121.7 BOOST. These represent reviews from the two sites I consider the most trustworthy and reliable in reviewing GPUs. This is MUCH more underwhelming than what we saw with Tahiti. This worries me a lot in regards to 290/290x.

For those providing anecdotal evidence of higher OCs, links please?

 

[njdevilsfan87]

Don't expect anything apart from a fully enabled GK110.

I'm not even expecting that. What would be the point? 5% faster than a Titan? Which means it will be negligible against a 290X. Unless they throw on 12GB of VRAM (for compute), I can't see the point for gaming or compute. If they do release a full GK110, I expect Titan to be discontinued.

Yes, I'd expect any full GK110 to completely replace Titan and those dies that have 1 bad or dodgy SMX and would have been Titans will be pushed down to either 780 or a 780 TI/ULTRA. Assuming Nvidia responds to 290X with anything other than pricing changes and marketing.
