GeForce 8800 GTS (G92) vs GeForce GTX 970M

Intro

Compare all of that to the GeForce GTX 970M, which makes use of a 28 nm design. nVidia has set the core frequency at 924 MHz. The GDDR5 RAM is set to run at a frequency of 1000 MHz on this particular model. It features 1280 SPUs along with 80 TAUs and 48 ROPs.

GeForce 8800 GTS (G92)		62080 MB/sec
	Difference: 33920 (55%)

Texel Rate

The GeForce GTX 970M should be a lot (more or less 78%) better at texture filtering than the GeForce 8800 GTS (G92). (explain)

GeForce GTX 970M		73920 Mtexels/sec
GeForce 8800 GTS (G92)		41600 Mtexels/sec
	Difference: 32320 (78%)

Pixel Rate

The GeForce GTX 970M will be quite a bit (about 326%) better at full screen anti-aliasing than the GeForce 8800 GTS (G92), and capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 970M		44352 Mpixels/sec
GeForce 8800 GTS (G92)		10400 Mpixels/sec
	Difference: 33952 (326%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
