GeForce 8800 GT 1GB vs GeForce GTX 965M

Intro

Compare those specs to the GeForce GTX 965M, which makes use of a 28 nm design. nVidia has set the core frequency at 944 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this model. It features 1024 SPUs along with 64 TAUs and 32 Rasterization Operator Units.

GeForce GTX 965M		60 Watts
GeForce 8800 GT 1GB		105 Watts
	Difference: 45 Watts (75%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 965M should be 11% quicker than the GeForce 8800 GT 1GB overall, due to its greater data rate. (explain)

GeForce GTX 965M		64000 MB/sec
GeForce 8800 GT 1GB		57600 MB/sec
	Difference: 6400 (11%)

Texel Rate

The GeForce GTX 965M should be much (more or less 80%) better at texture filtering than the GeForce 8800 GT 1GB. (explain)

GeForce GTX 965M		60416 Mtexels/sec
GeForce 8800 GT 1GB		33600 Mtexels/sec
	Difference: 26816 (80%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 965M is a better choice, by a large margin. (explain)

GeForce GTX 965M		30208 Mpixels/sec
GeForce 8800 GT 1GB		9600 Mpixels/sec
	Difference: 20608 (215%)

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 transported across the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate 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 fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
