GeForce 8800 GTS (G92) vs GeForce GTX 965M

Intro

Compare all that to the GeForce GTX 965M, which features a clock frequency of 944 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 128-bit bus, and makes use of a 28 nm design. It features 1024 SPUs, 64 Texture Address Units, and 32 ROPs.

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 speaking, the GeForce GTX 965M is 3% faster than the GeForce 8800 GTS (G92) in general, due to its higher data rate. (explain)

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

Texel Rate

The GeForce GTX 965M should be quite a bit (more or less 45%) faster with regards to texture 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 will be a lot (more or less 190%) more effective at 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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 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 amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could 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 Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
