More flops = Output.Bertster7 wrote:
The fact that the FLOP rate is 3x higher does not mean the card will be 3 times faster, although it could be even quicker than that due to a number of other extended features. It is also rumoured to draw less power than the 8800.
Without knowing more about the architecture it is almost impossible to predict how the card will perform, even then there's no real substitute for proper performance testing.
I didn't expect a new Nvidia GPU series out so soon.
No. More FLOPs = more FLoating point OPerations. What about integer operations? What about CPI? There are lots of other factors that are concerned with the architecture. The instruction set itself will play an important role as will the efficiency of a the pipeline (which will be an enhancement on the existing stream processing technology, combining vertex and pixel shaders, to perform T&L and rasterization concurrently). There are many important factors, you can't tell much from one of them on its own.cyborg_ninja-117 wrote:

it is very likely to be dual core chip. and combined with 50% increase in performance/core it would be theoretically 3x faster than 8800gtxBertster7 wrote:

I'm not saying it won't be. I'm just saying don't start judging it on the FLOP rate. It's not a good indication. It's like judging it by clock rate - inaccurate. these things can only be used in comparison to over chips using the same architecture and we don't know what the architecture is yet. This is just more ill informed people jumping to conclusions before any real information is out.[69th_GFH]GC_PaNzerFIN wrote:

You don't like the fact that since technology is moving so fast, better components are becoming cheaper more quickly? How does that make things more expensive, unless you need to buy the best of everything straight away, which you don't - since software doesn't keep pace with these new hardware developments.Jello.01 wrote:

Technology is moving wayyy too fast, I don't like it, since I don't have an infinite amount of money at my disposal.
yea. have you seen those benchmarks about 2900xt shader power? it's 2x faster than 8800gtx! but because it sucks in pixel power it gets pwned by 8800 seriesBertster7 wrote:

Remember the R600 that was going to blow the 8800 out of the water? The 2900XT appeared and is nothing super special - despite having a higher FLOP rate than the 8800GTX. Which gives a good indication that FLOP rates are not a good thing to judge performance by.
A 4GHz P4 is significantly slower than a 2GHz C2D.cyborg_ninja-117 wrote:

Since we're using rasterized graphics, pixel power is very important. Good performance in one field is unacceptable, it is overall performance designers want. The 2900XT does not deliver.[69th_GFH]GC_PaNzerFIN wrote:

is it really that much?damn,that's more than my computer costs all together.surgeon_bond wrote:

There is no way it'll cost that much. A 3rd of that perhaps.aj0404 wrote:

Whatever the price tag will be, I'd like to see something similar to the 8800GTS 640/320-solutionBertster7 wrote:

I'm sure you will. The GTSs have been very successful. I'm sure Nvidia plan to build on that success by doing more of the same.Stormscythe wrote:

yeah, AMD/ATI is in big trouble cuz of 8800GTS. and when G90 is released amd will be even more in trouble.Bertster7 wrote:

Nvidia make a lot of brash claims about GPU FLOP rates. Remember when quad SLI came out? 6TFLOPS, apparently. Maybe so, but that power is not usable due to the way the cards are set up.topal63 wrote:
3D-Graphics are a pipeline of FLOPS (for tessellation) and more FLOPS = more frames per sec. (FPS) = faster card, in theory.
But the Graphics-Card has a CPU dependency; and has a code-dependency. The game-code (game-engine) is CPU related and structured in a linear fashion (usually). The GPU-pipeline will stall if it is waiting on an instruction being executed by the CPU.
It doesn't matter if the card is faster (more FLOPS) if:
1.) You have a slow/slower CPU.
2.) The coding of the video-driver is not state of art.
3.) The coding in DX9 (and its relation to the game-engine) doesn't support the advances included in the new/newer card design.
4.) The game itself can't take advantage of increases in resolution (res. modes).
5.) The meshes and textures in game are of lower resolution than the card is capable of supporting.
6.) Parallel processing (taking advantage of dual/quad core technology) has to be implemented in the: video-driver, in DX9 or DX10, and/or in the game engine itself; to make sure the 3D-graphics pipeline is not waiting on the CPU - so that FLOPS = FPS = the actual performance threshold is realized.
3x FLOPS will equal more FPS, but not 3x FPS, the increases in speed will be a percentage increase, and that (% increase in performance) will be dependent upon all those other things mentioned.
SLI's main advantage is not FPS at lower or normal resolutions - here there is little or no improvement in FPS. Currently, SLI is really all about AA and/or Higher Resolution FPS (with AA enabled). But once again there is a dependency to Code issue. Greater resolution = more pixels per view on triangle faces = more FLOPS needed = a FRAME occasionally being hung (or feeling like the action is stuttering) while waiting on Code being processed by the CPU. All game titles (now) are either OpenGL or DX9; and they are very linear (not much parallel code execution happening in current game titles). An SLI rig needs a good CPU to make it all run smoothly at higher resolutions (or with 16x AA enabled).Bertster7 wrote:

So is it fair to say that G92 cards will be 6x slower than a quad SLI setup? Of course not. Many other factors will play equally important roles. The GPU pipeline is extremely important in actually harnessing the power of the GPU efficiently - but the unified shader architecture seems to do a very good job of most of that stuff, so it's good to hear they are extending that.
