GeForce 7600 is only 8 pipe!!

[A554SS1N]

According to xbitlabs, the 7600 Go mobile series are only 8 pipe cards, so that is likely what the desktop versions will be. Link: 7600 Go Info.

But don't get worried, the GeForce Go specs mentioned clock rates of 450Mhz and 1000Mhz GDDR3, and if that is anything to go by, any desktop GT variant could be much higher. The following quote shows reasons to be happy:

The GeForce Go 7600 sports 8 pixel processors, 5 vertex processors, 8 raster operation units (ROPs), 8 texture mapping units (TMUs) and sport a 128-bit memory controller according to a spec sheet provided by Nvidia Corp. The new chip is produced using 90nm process technology. Notebook manufacturers are allowed to clock the GeForce Go 7600 at up to 450MHz for chip and up to 1000MHz for memory.

So it has 8 ROP's (and more vertex shaders than 6600) - meaning that the full use of those 8 pipes is made, meaning it could well easily outperform an X1600 12 pipe card limited by 4 ROP's. I must admit I was hoping for 12 pipes with 8 ROP's (is there still a chance of that for the desktop chip?) but we'll just have to see how performance goes. Obviously NVidia have decided this is the best compromise and chip production cost and performance for the mid range, so if the chip turns out fast, it'll make more sense.

I was hoping for 12 pipes as well, but I hope this will suffice to beat the X1700... I don't think ATI's going to make the same mistake twice... However, this makes me pretty happy actually... This way I know the 6800GS I recently bought, should not be outperformed by it...

EDIT: Could always be that the desktop variant has 12 pipes, but I'd rather see it having a 256-bit memory bus...

Heh, 6800GS should slaughter it!!! Maybe some hope in pure speed apps if the GT version has a high enough clock speed, but it'll have to be in the 650Mhz range.

Hehe

It would have sucked if it were the other way around... There will be some benchmarks where the 7600 will shine (prolly the 3DMarks), but other than that, I don't really see it kicking GS-b*tt (given that the specs are indeed 8 pipes and 128-bit mem bus)...

 

[A554SS1N]

Just checked my trusty Excel spread sheet I setup, and it works out exactly at 638Mhz that it would have the same fill-rate. But with the memory, it'd need 1800Mhz memory to get even close with a 128 bit bus (which would work out still behind at 28.8GB bandwitch compared to 32GB for the 256-bit GS).

Probably similar to 6600GT versus 6800 vanilla type scenario in purespeed (i.e. an advantage with the 6800, with the odd clock-speed dependant game swapping things around), and then falling miles behind in AA+AF situations. That's assuming it's given a high core clock - if it's less than 600Mhz then.. oh dear...

Possibly the only advantage it may have is lower power consumption/and shorter card design enabling it to fit it small cases.

 

[Wentelteefje]

Seems right to me... However, my 6800GS hits 520/1200MHz, so I don't think the 7600 will be touching that... We'll see about it...

 

[A554SS1N]

With those clocks you'll be beating a 6800ultra easily!!! Nice OC!!!

 

[Wentelteefje]

Yeah I know... It did cost me a NV Silencer however... More than worth it I'd say...

EDIT: Some time later I'll try the VR-Zone volt mod...

Maybe ATi Will pull a 6600GT (How it owned the x600) with the x1700?

Normally, it should be (much) better... The X1600 wasn't aimed at the 6600GT (although it could hardly compete with it), but at the 6800GS/X800GTO level of performance... It remains to be seen however, but IMO, the 6600GT shouldn't pose a threat...

 

[IlllI]

i'm guessing the 7600 will be replacing the 6600 and have similar/slightly higher performance.

 

[NoStateofMind]

So I guess If you were looking for a 6600GT now, It would be better to just wait for the 7600GT huh?

LOL yeah, the 7600 and X1700 should be better... However, in your case, I doubt there are going to be AGP versions of 'em... Could always be of course... Their introduction will probably make the 6600's price lower as well...

Have your money already?

Depends - if you're looking at 6600GT now because of price, 7600GT will debut at an initially higher cost putting it in a different price range, at which point a 6800GS would fit the bill. I suppose it's worth waiting for more details on specs a little longer.... depends what you're after performance wise - a vanilla 7600 at those 7600 Go specifications would probably work out similar to a 6600GT in performance. 7600 would likely be more economical on power consumption, so that may be worth waiting for..?

If it'd come out in AGP...

Nope, no money. Gonna have to take other measures to retrieve it I guess

As for the post about the 6600GT, I was refering to the PCIe version, the one's that are looking for low end should wait for the 7600. But I see how you could be confused

I know what you are looking for... Sorry to hear the money's still not OK... We'll have to wait for them to arrive, and then we'll see how the market will take on 'em (dropping prices on 6600's etc.)...

Yeah, but how well do you think it will do against a x1700 if that thing has 8 pipes and 24 shaders? I suspect that's what the x1700 is gonna be.

That's what I said before... It's no direct competitor... It should be better...

That'd be mighty expensive to produce for a mainstream card

Could be true, but ATI really will probably hold onto its principle of 1:3...

Yeah I stopped waiting for this card when I read about the probable 128-bit mem bus.

256 Bit Memory Bus is going to be limited to high end cores in most likelyhood.

Yes, I could see how this would worked if this card was clcoked at something like 700MHZ or around where G71 is rumored to be plus paired with 256MB or either 1.4ns or 1.2ns GDDR3. The RV530 is also limited by it's 4 TMU's, as well.

Well 12 Pipes and 8 ROP's is already here with the NV42 chip, it's just clocked low in comparison to the RV530.

So based on 90nm low k, i would expect clocks as high as 600~700mhz. Remember that 6600GT based on 110nm (not lowk) was clocked at 500. The 7600 "pipeline" is 1.5 times faster than the 6600 "pipeline".

We could expect around 1200mhz on memory scaling down from the rumorued 7900 GTXs 1900 mhz memory speed. Maybe even higher, because a 7300GS is also rumoured to use 1.4ns GDDR3 rams (although 128bit).

In the end, for a MSRP of 249 the 7600GT looks something like this.

90nm low k
600~700mhz core clock
8 pixel piplines
8 ROPs
5 VS
1200~ mhz memory clock
128bit GDDR3 (256bit?)
128/256mb
