GeForce 8800 GTS (G92) vs GeForce GTX 965M

Intro

Compare all that to the GeForce GTX 965M, which has core speeds of 944 MHz on the GPU, and 1000 MHz on the 2048 MB of GDDR5 RAM. It features 1024 SPUs along with 64 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 965M		60 Watts
GeForce 8800 GTS (G92)		135 Watts
	Difference: 75 Watts (125%)

Memory Bandwidth

Theoretically, the GeForce GTX 965M should be a little bit faster than the GeForce 8800 GTS (G92) in general. (explain)

GeForce GTX 965M		64000 MB/sec
GeForce 8800 GTS (G92)		62080 MB/sec
	Difference: 1920 (3%)

Texel Rate

The GeForce GTX 965M is much (more or less 45%) more effective at anisotropic filtering than the GeForce 8800 GTS (G92). (explain)

GeForce GTX 965M		60416 Mtexels/sec
GeForce 8800 GTS (G92)		41600 Mtexels/sec
	Difference: 18816 (45%)

Pixel Rate

The GeForce GTX 965M is a lot (about 190%) more effective at full screen anti-aliasing than the GeForce 8800 GTS (G92), and should be capable of handling higher screen resolutions while still performing well. (explain)

GeForce GTX 965M		30208 Mpixels/sec
GeForce 8800 GTS (G92)		10400 Mpixels/sec
	Difference: 19808 (190%)

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 information (in units of MB per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
