GT200 specs

[Revs]

I would. Look how much thinker the line is between the GPU's on the R700 series chip :captnkill:

That's one THICK line!!

Honestly though, the lack of a PCIe switch should make a difference. I wish it was in English.

[slaWter]

That PCIe Switch chip is the problem IMO. Didn't AMD say something about a PCIe 2.0 Switch chip for the new X2, as an improvement over the 3870X2? Plus did you guys see the '?' in that picture....

[Revs]

Well noticed :D

I was too busy looking at the MCM.

Whatever, it's an improvement in the right direction, for better multi-chip performance.

With this enhancement, the 2 chips will share the memory, and prolly better CF scaling performance.

Copyright 2007? Seems more like a guess than anything.

lol, ATi must have read my sli 2.0 wish list thread from 3 years ago...

[Viral]

I really hope they do go down the shared memory route with some kind of fast link between the cores, but so far, the leaked R700 cooler pics prove that the chip and memory layout is the exact same as R680.

Both the GeForce GTX and Radeon HD 4800 series will arrive in about three weeks. Each series will bring two new cards to the market; GeForce GTX 280 and 260, and Radeon HD 4870 and 4850. There is a big difference between the cards though as the GeForce GTX series is enthusiast range, while Radeon HD 4800 series is more mid-range. There have been talks of what GeForce GTX 280 can do in Vantage, but it has now been completed with figures for the other cards.

These are of course in no way official and we can't say for certain where they come from. The only thing we know is that the numbers are not unreasonable, but some information about the rest of the system would be nice. ATI performance (with all cards) is still subpar due to poor drivers, and should improve in Vantage with coming releases. The numbers that are circulating the web are something like this;


Graphics card Vantage Xtreme profile*
GeForce GTX 280 41xx
GeForce GTX 260 38xx
GeForce 9800GX2 36xx
GeForce 8800 Ultra 24xx
Radeon HD 4870 XT 26xx
Radeon HD 3870X2 25xx
Radeon HD 4850 Pro 20xx
Radeon HD 3870 14xx
* 1920x1200 4AA/16AF



I hope these are false. :)

[Revs]

Looks about right to me. The GTX280 is more or less a GX2 merged in to one card with slightly more efficient architecture. Don't forget it will also be far less CPU limited at lower res'.

If that Radeon HD 4870 XT score is correct, that's awesome! It means ATI's X2 card will piss all over the 280 if ATI get the drivers right, at the same time being cheaper and less power hungry.

I can see ATI having a very good year. I just hope they're not selling at a loss. They need to get some pennys in the bank.

[Viral]

Yep, if it can surpass an 8800U like that then that's not bad at all, also keeping in mind the note on the immature drivers. They seem pretty reasonable to me.

[Revs]

If nVidia don't sort this full screen video crashing problem with the 780i chipset very soon I might just have to build myself my 1st Intel/ATI rig.

The main reason I want ATI to do well is so I can point and laugh at Tygerwoody :D

I'm very interested is seeing that work.:)

Back to geforce 280 gtx, those vantage numbers look very nice.Now for some game benchmarks! :D

"Nvidia GT200 sucessor tapes out"

http://www.theinquirer.net/gb/inquirer/news/2008/05/29/nvidia-gt200-sucessor-tapes

The answer to that is to tape out the GT200b yesterday. It has taped out, and it is a little more than 400mm^2 on a TSMC 55nm process. Given that TSMC tends to price things so that on an equivalent area basis, the new process is marginally cheaper than the old, don't look for much cost saving there. Any decrease in defectivity due to smaller area is almost assuredly going to be balanced out by the learning curve on the new process. Being overly generous, it is still hard to see how the GT200b will cost less than $100 per chip. Don't look for much cost savings there.

The new shrink will be a much better chip though, mainly because they might fix the crippling clock rate problems of the older part. This is most likely not a speed path problem but a heat/power issue. If you get a better perf/watt number through better process tech, you can either keep performance the same and lower net power use, or keep power use the same and raise performance.

Given NV's woeful 933GFLOPS number, you can guess which way they are going to go. This means no saving on heatsinks, no savings on components, and a slightly cheaper die. For consumers, it will likely mean a $50 cheaper board, but no final prices have come my way yet. It will also mean a cheaper and faster board in a few months.

The GT200b will be out in late summer or early fall, instantly obsoleting the GT200. Anyone buying the 65nm version will end up with a lemon, a slow, hot and expensive lemon. Kind of like the 5800. It would suck for NV if word of this got out. Ooops, sorry.

GTX290 ? ;)

OMG, how biased is that?

[mtl]

Riiiiight! Nvidia's products are sooo bad they make record revenues and profits every year while ATI and AMD struggle to stay afloat. And the 2900xt just destroyed the 8800 GTX.
This guy's on crack.

LOL, that guy is such a douche. His numbers seem to be mostly accurate though, NV is going to have a tough time this cycle because the GT200 parts are both expensive as hell.

Charlie has a big hard on for Nv for some reason. Or maybe he is just miffed....or his ego has taken beating since NV do not leak stuff to him and has instructed OEMs not to do so too.

It seems to me the opposite, that he doesn't like Nvidia. Though what he says, if true, is pretty spot on.

[Viral]

It's true, nVidia won't have a very cost effective or energy efficient chip. But him saying it will be slow is just bias. GT200 will undoubtedly perform very well, but ATI's approach with RV770 may end up the better option despite it failing to reach performance parity with GT200. If ATI have designed an efficient link between chips for an MCM style R700, it will truly revolutionise the GPU industry. Being able to make one chip for all market segments would save a lot on R&D and manufacturing. Comparing it to SLI or Crossfire isn't doing it any justice, we're talking about a dual chip setup that is recognised as a single chip as actually functions like one.
