GeForce 8800 Ultra vs GeForce GTX 970M

Intro

Compare that to the GeForce GTX 970M, which comes with a core clock frequency of 924 MHz and a GDDR5 memory speed of 1000 MHz. It also makes use of a 192-bit memory bus, and makes use of a 28 nm design. It is made up of 1280 SPUs, 80 TAUs, and 48 ROPs.

GeForce GTX 970M		96000 MB/sec
	Difference: 7680 (8%)

Texel Rate

The GeForce GTX 970M is quite a bit (more or less 89%) faster with regards to anisotropic filtering than the GeForce 8800 Ultra. (explain)

GeForce GTX 970M		73920 Mtexels/sec
GeForce 8800 Ultra		39168 Mtexels/sec
	Difference: 34752 (89%)

Pixel Rate

The GeForce GTX 970M is a lot (approximately 202%) better at AA than the GeForce 8800 Ultra, and able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX 970M		44352 Mpixels/sec
GeForce 8800 Ultra		14688 Mpixels/sec
	Difference: 29664 (202%)

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 maximum amount of data (in units of MB per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
