A quick look at the chart below will tell you the differences between the 192-bit 8800GS and other 8 series. The price tag of 8800GS 384MB will be 1199CNY or about 164USD, while the 768MB version will cost 1499CNY (~204USD). Redirect here for some more pics and results.

OMG this is insane...another variant of the 8800, it losing sense flooding the lineup this way. Maybe this is to counter the sudden rise in the sales of the HD2900 Pro

It just seems to me Nvidia is bit confused of the current situation where ATI does not even try to compete in the high end currently. Nvidia have great products for sure but just don´t seem to know what to do with them. The sheer amount of different products out there with Nvidia name slapped on them is proof enough in my opinion.

nvidia is confused.? what about the poor gamers, getting lost in all this 192/256/112/96/90/65 mess? i myself have difficulty following all these variants :ohwell:

An 8800 GS that will be more powerful than the 8800 GT?
This should have been 96 SPs.

Weer,
GS has 192bit bus, GT wins at 256bit.

Confuse and sell....so that the consumer concentrates less on the specs, more on the name

Hooray I got a GeForce 8800 !!!

Which 8800?

I dunno.

...new tactic from NVidia.

192bit??? WTF? I thought it went like 64-128-256-512-1024 etc. I know the old G80's were like 768 or w/e but 192? Thats pretty lame =/

The G80's were 320bit and 384bit (GTS, GTX)

Now the other news is just silly about "NVIDIA Asks Card Makers to Reduce Manufacturing Costs of 8800 GT Cards". Why should the 8800GT go down in price as that 8800GS 768MB is clearly targeted to HD 3870 and 8800GS 384MB to the HD 3850.

arent the gt's 45nm? that chart states that they are 65, is it being generalised or something, or am i just lost in all the different modelseZeses o.0

Nope 65nm :) They went down from 90nm G80.

I doubt it can compete with the 256-bit awsomenessosity of the HD 3850 :nutkick:

They go in steps of 32:
32bit (1)-64bit (2)-96bit (3)-128bit (4)-160bit (5)-192bit (6)-224bit (7)-256bit (8)-288bit (9)-320bit (10)-352bit (11)-384bit (12)-416bit (13)-448bit (14)-480bit (15)-512bit (16)-etc.

All these bus widths are possible to make but only those bolded have been done, the "(number)" in the list after each bus width means the minimum number of GDDR3/4/5 chips that are needed.
Bus width = amount of chips working in parallel.

ShadowFold,
GDDR3/4 chips used therse days are 32bits "wide" ie. 32bits can be read/written at the same time. If you put 2 such chips on a video card you get 64bit bus - that means the GPU can read/write 64bits in/from it's memory pool in a single clock cycle. Put 10 chips and you'll get a 320bit bus (10×32bit) just like on the G80 based 8800GTS 320MB/640MB. 8800GTX/Ultra has 12 chips yielding a 384bit bus (12×32bit). 8800GS has 192bit bus thus it has exactly six GDDR3 chips on board (6×32bit).

They can keep bringing on the cheap cards I say... :p
Talk about confusing though.

Well W1zzard got 8876 with E6550 & HD 3870 in 3DMark06 and that screen shows 9826 3DMarks with E6750. That lower-clocked-half-memory-8800GS one should not follow too far behind as it's just like HD 3850 is to HD 3870.

No, the GT does not "win".

The 64 extra bit on the memory bus aren't going to make much difference in performance.
Where as the extra 100Mhz memory clock on the GS and the extra 50Mhz core clock will.

Performance should be on-par if not superior.

I still say it's a type-o, and I say that you are condesending. If you really thought I'd be stupid enough not to notice the difference in memory bus, you'd have to be pretty pathetic to call me out on it.

I think this product is directed at oem vendors wanting a cheap 8800 to beef up the specs of their retail systems.

Weer, don't forget that the 8800 GS has 4 less ROPs than the GT as well.

That said, given the higher clocks of the 768MB GS model, I'd agree that the number of SPs is probably a typo - especially given that the core clock is 50MHz higher than on the 8800 GT, and nVidia cards have traditionally seen greater performance from higher core speeds as opposed to higher memory clocks.

Still, it'll be interesting to see exactly what effect - if any - the 192-bit bus has on performance. Given that 128-bit cards have generally been poor performers and 256-bit cards the opposite, it might be the case that a 192-bit bus is just a little too restrictive for the G92 core. Time will tell...
