Nvidia GTX290? GT200b 55nm 3Q 2008

NVIDIA says it will win back performance leadership this year
http://channel.hexus.net/content/item.php?item=14993&page=2

The two people we speak to are Nick Stam (pictured), the technical marketing director for GeForce and Bryan Del Rizzo, PR manager in the US. We start by asking them what they feel about losing the performance leadership.

"Is that interesting?" says Del Rizzo. "To some people maybe, but it took two of their GPUs to beat one of ours. We have had dual GPU cards and it's feasible that it may happen again."

That last point was intriguing. In our review of the 4870 X2, HEXUS.net editor Tarinder Sandhu said: "We'll have to wait for the GTX 200-series to go on a process diet, to 55nm, and then, just perhaps, we'll see a GX2 based on GeForce GTX 260."

While we're unable to draw either of them on whether or not this will happen, when we ask them if they expect to regain the performance leadership this year, Stam says "Yes".

That's as much as you're going to get on that topic for now and we move swiftly back to the 4870 X2. "Is that product the best product you can buy for a PC?" asks Del Rizzo. "A lot of people care about power consumption. Two GTX 260s have lower power consumption than one 4870 X2. In the Asia-Pacific region, for example, they're sensitive about power consumption."

Stam is keen to point out that he thinks NVIDIA's multi GPU platform has advantages over AMD's. "We've done our own testing of SLI vs Crossfire and we see a lot of issues with Crossfire. SLI is far more developed and doesn't have as many issues."

nice find i was thinking about that power draw as well full load on them x2 cards are 110watts more

also you no that is scan computers (uk) foram was going to go up there and ask this above no need to now .

[lee63]

I hope its before my step up ends, I have 44 days left :D

step up? thought they only did that on relase cards

[mtl]

Nvidia has fantastic cards coming. I much prefer single GPU anyway.

according to what walter posted, they are coming this year

Nvidia wants its crown back
http://www.fudzilla.com/index.php?option=com_content&task=view&id=8951&Itemid=1

Beware ATI

We've learned that Nvidia is working hard to get its performance crown back. Nvidia is planning to introduce a few products that might change the game, but it doesn’t look that rosy for the green goblin.

The first projection are showing that if GT200 55nm as an optical shrink of GT200 65nm won’t have enough performance headroom to beat the Radeon HD 4870 X2 also well known as R700 card. No matter how high they clock, it might not be enough.

Nvidia might be adding some more horsepower to this chip and the thermals will be much better which might imply that there is a change. GT200 55nm with more Shaders and some additional architectural adjustments might have a chance.

Currently, RV710 and RV730 will hit Nvidia the most, in entry and mainstream level, and this is where the volume sales are. These chips are going the hit the cash cow called Geforce 9500GT and 9400.

"No matter how high they clock, it might not be enough." Agree with Fuad here. The difference in shading power or memory bandwidth is huge, for a single chip card. But, maybe a GX2 style card with 2x "GTX260b" chips could be possible at 55nm.

[hemmy]

IMO, the most likely GX2 is also a 55nm GTX 260, or 260+ w/e they want to call it and it would probably have around FTW speeds or even closer to 700

That would probably be enough to outperform the X2, except those games that just love the ATI architecture - Grid, Call of Juarez, etc.

4870X2 -> 2 x 750 MHz x 800 SPs x 2 Flops = 2400 GFlops

GTX280 -> 1 x 1296 MHz x 240 SPs x 3 Flops = 933 Glops

In the worst case, the ATi chip could deliver only 1/5 of the shading power = 480 GFlops (when you only can extract 1 op of the shader code per clock cycle).

ATI only needs to extract (933/480 = 1.94) 2 ops per clock cycle to outperform the GTX280 (easy).

The 4870 needs to extract (933/240 = 3.88) around 4 ops to outperform it (complicated).

I also heard that the dual issue in the GT200 isn't working very well, so, it could end with 622 GFlops.

Translation: developers must write the shaders to exploit the parallelism.

[CaptNKILL]

Remember though, that's just shader processing.

The actual rendering speed has little to do with the amount of Flops the SPs are capable of processing.

This is how you can get cards with 64, 96 and 112 shader processors that perform almost the same in all but the most shader heavy games. When the resolution and AA go up, its less about the SPs and more about fill rate. As it has always been.

[walterman]

You need to feed all that shading power, of course. :)

GT200 55nm to come in Q4 2008

Won't launch at Nvision

We've learned that Nvidia is working hard to launch GT200 55nm but this will most certainly won't happen in August or September. Our sources imply that this will take place in Q4 2008.


Nvidia simply wants to win the performance crown back from R700. Adding GDDR5 memory and 55nm process will certainly speed things up and they will take the dissipation down.

Thermal dissipation is Nvidia's biggest problem as the chip turns to be extremely hot and the new 55nm should be a bit better. Once you take care of thermals, you can clock the chip higher which eventually means more performance.

The 55nm process with a new clock and GDDR5 memory should get GT200 55nm a bit faster than R700 and this is exactly what Nvidia needs.

Come on, i want my 512bit bus with GDDR5 :drooling:

I think that's going to be very hard for them to pull off. The costs would be too much. I think they also stated they're moving to GDDR5 in a couple of generations.

[nekrosoft13]

seems like my step up will run out by that time

[walterman]

Do you remember nVidia's answer to the x1800XT after the 7800GTX ?

It was the 7800GTX512, and if you remember, this card featured a huge increase in the memory bandwidth (56GB/s vs 34GB/s -> 64% bigger), and the performance gains were awesome.

So, bring me that 512bit bus with GDDR5 :drooling:

[namuk]

and it cost allot of money + they had alot of trouble with them

Yes, but that was pure clock speed increases. They didn't change anything architecture wise. I think this will be a bit harder to pull off, with pure clock increases. I hope they do, competition always drives prices down and performance up... :)

[walterman]

The most expensive part in the GTX280 is the 512bit PCB. You can save more money using a 256bit PCB combined with GDDR5.

Nvidia has been using GDDR3 since the NV40 (6800 Ultra), so, they had 4 years to think & design new memory controllers.

Also, 450E for a 2GB GDDR5 4870X2 isn't expensive, compared to the 600E that the 1GB GDDR3 GTX280 costed on launch day here.

so the main cost has allready been done? yes

[MisterMister]

Basically.

1080 GFlops / (240 SPs * 3 Flops) = 1500 MHz +-

Just speculation, but, this could be the shader clock of the GT200b.

The rest of params seem unchanged.

Also, check the bw in year 2013 :)

interesting that . sneaky c##ts 2013 lol yea seen that

[bakalu]

GPU 2013 : 20 TFLOPs = 20000 GFLOPs / (3 Flops * 1500 MHz) = 4444 SPs:captnkill::captnkill::captnkill:

[nekrosoft13]

maybe they have a working prototype already ;)
