GeForce 9800 GX2 clock speeds revealed

[JPB]

Expreview has got their hands on what they're claiming are the final clock speeds of the GeForce 9800 GX2 and if these numbers are indeed correct, then this card might not be as fast as expected.

The GPUs will be clocked at 600MHz, that's 50MHz slower than the 8800 GTS, or the same as the 8800 GT. The Shaders will apparently be clocked at 1,500MHz, again slower than the 8800 GTS which has its Shaders clocked to 1,625MHz.

The memory clock is somewhat higher at 1GHz or 2GHz effectivley for the GDDR3 chips, but this is a mere 60MHz faster than a stock clocked 8800 GTS and is unlikely to make a huge difference.

Not exactly spectacular numbers, but the cards are expected to run quite hot as it is, especially with the two GPU's facing eachother, so the lower clock speeds might have been a safety precaution on Nvidia's behalf to make sure they don't end up with a lot of returns.

Does the 8800GTS512 support OpenGL 2.1 ?

According to the specs here it does.

In your expreview link, it says this at the bottom of the paragraph:

"The core clock is similar to 8800GT?s, but as you can see, memory clock raised up to 1000MHz. Also, source mantioned the card supports OpenGL 2.1.(8800GT only supports OpenGL 2.0)."

But in your GPU review link, I compared both GTS512 and a GT and it says they both support OGL 2.1.

Basically, I was trying to discern any core differences from an standard G92. Since this new card is called a "9800" GX2, I was wondering if these cores had the same tweaks as the new 9600GT with the G94 core. Rather than being 2 G92 GTS's slapped together.

Damn!! Now I'm really confused...

Only thing I know is that the 9800GX2, aesthetically, looks really nice (IMO) but I don't think I like the prospects of the heat issue. OCing those are going to suck.
Where is the 9800GTX?
I think that is where the real upgrade will be. Thoughts?

I don't know what to do about my video card situation...

1) Single GT ($240)
2) Single GTS ($290)
3) Dual GT ($480)
4) Dual GTS ($580)
5) Keep 320MB ($0)
6) Keep waiting for 9800GTX ($0)

NOTE: Resale value of my 320MB is $200.

Well, wait. You have an 8800Series, which is good as-is. I don't think this card is very good anyway. If you wanted a $400+ option anyway, I'd get the HD 3870x2.

Hmm... When I try the site, I get: Fatal Error: Out of memory. Tried to allocate ( ), allocated ( ) in an address that doesn't exist on my computer.

Based on those clocks, I don't see why anybody w/out a step up option would go for it.
1. It doesn't support 3 way sli
2. It won't overclock very well due to thermal limitations.
3. The clocks are basically what you get out of a stock gt.
4. While we don't know what the prices are yet, I think its safe to assume that you can get 2 gt's sli for less or comparable.
5. The power requirements look sick. Two power connectors for one card(ok 2 in 1 but still its silly)
6. The only plus over a 8800 gt sli config is the "quad-sli" argument(which everybody on the forums seems to have a bad taste over from the 7900 experiment) or they want this on a x-38 or x-48 board because of lack of sli support.

I say all this as a very disappointed EVGA step up participant who is not going to waste the money on this card. I think I'll just get another 8800 GTS in a few months so then I can step up my current card for the extra cash and use that for the difference in the step for the 9800 gts. I'm very disappointed in this news but even happier I didn't sit on my 7900 gs any longer than I did.

did you miss one?


5a) Keep 320MB ($0) ... add 320MB ($200 total)

?

7. There probably won't be any 3rd party coolers.

Can this card be tripled for 6x Sli?

exactly!

oh and
8. Nvidia doesn't like Dual GPU (Yes I intentionally worded the link to make it more inflammatory)

If the brass at Nvidia don't like the architecture, why should anybody else?

 

[taltamir]

I think the nvidia claim there is more along the lines "well... the 3870x2 might beat the ultra... but multi GPUs are bad so the ultra is still the best card on the market" actually thats verbatim what he said...

Anyways... what would you rather have... 4x 3870 cards in a 4 slot PCI machine... or a single 9800GTX getting a little less performance, but costing less, and require less then 1000+watts PSU... (more along the lines of a 400watt)...
I'll take the single card thank you very much.
