G92 Has New Compression Technology

It has come to our attention that the GeForce 8800 GT and GeForce 8800 GTS 512MB have a new compression technology inherent to the G92 GPU. There are physical transistors inside the GPU, plus some new algorithms, that allows better data compression across the memory bus, making the process more efficient. This is important because of the narrow 256-bit memory bus, and since it is inherent to the GPU that means a lower spec GPU may use this technology as well providing a performance advantage.
 
Nope. The GX2 is still a half-baked product in my book, regardless of any fancy and probably quite meaningless compression technologies.

That's not to say I don't want such technologies in NVIDIA's next true high end product.
 
Good to know.

Haven't heard of much in the S3TC or DXTC compression front since RAM prices took a nosedive.

Still - Anything that allows more textures is a good thing. The megatexture seems to be working just fine in Quake Wars, and better compression can only mean more realistic detail (IE: less texture duplication, higher res, or visually clearer textures)
 
So whats with the ever shrinking memory bus. I haven't been keeping up on this latest G92 core, i actually didn't even know it was out there, but the 8800 series as essentially gone from 384 bus, to 320 bus in the GTS, to now a 256bit bus with the new GTS on G92.... someone correct me if that's wrong.

I don't know the differences between the G92 core and the G80 benchmark wise but it would seem they did this to lower heat output? or cost. I'm not sure how it would increase heat to have a bigger bus but I also don't know why you would shrink the die, add more stream processors, and then create a bottleneck.

Anyone care to explain what the hell is going on?
 
Simple- the 8800GTS G80 was a cheaper 8800GTX with fewer sp's, less memory, and a smaller bus (aka, less performance- you get what you pay for). The 8800GTS G92 packed-in 33% more stream processors with clocks on all of them that exceeded those on even the 8800 Ultra. However, to keep the price down (and possibly because of the technology from this news posting), nVidia gave it only a 256-bit bus. Of course, they also could have done this to ensure the continued relevancy of the 8800GTX and 8800 Ultra (both of which have higher price points).
 
I haven't posted on here in forever.. where's the edit button?

Whats the status on the true next generation chips or is everyone assuming they're going to just keep phasing in the G92 for the higher end products and just up the memory bus while waiting for AMD to get more competitive?

Assumption atm is that nVidia is "waiting" on AMD- from what I've seen, it looks like they'll arrive some time in Q2 '08.

I have been saying this for months. ;)
 
I think I am going to get one when they come out. I was going to get a 8800gtx but might as well wait now
 
I'm severly dissapointed in the 9800GX2 simply because it'ss only 2 8800GTX slapped together with a fancy new chip. It's got nothing new in it and it's not going to get my purchase. Until something actuallly NEW comes out fron nVidia I'm sticking with my watercooled 8800GTX.

Feel free- I have a feeling the 9800GX2 and 9800GTX are not being aimed at those who already have OCed 8800GTX's- they seem to be aimed more at those who must always have the fastest card available and those who skimped on their last 8 series purchase (maybe went for an 8600GT/GTS or 8800GTS) or who have not yet upgraded to the 8 series but are looking to upgrade nevertheless.
 
Doesn't mean anything until they can show these imporvements when it gets reviewed, then we will see if it's any good.
