GeForce 8800 GTX vs GeForce GTX 965M

Intro

The GeForce 8800 GTX makes use of a 90 nm design. nVidia has clocked the core frequency at 575 MHz. The GDDR3 memory is set to run at a speed of 900 MHz on this particular model. It features 128 SPUs along with 64 Texture Address Units and 24 ROPs.

Compare those specs to the GeForce GTX 965M, which features GPU clock speed of 944 MHz, and 2048 MB of GDDR5 memory running at 1000 MHz through a 128-bit bus. It also is comprised of 1024 Stream Processors, 64 TAUs, and 32 Raster Operation Units.

GeForce GTX 965M 64000 MB/sec
Difference: 22400 (35%)

Texel Rate

The GeForce GTX 965M is quite a bit (approximately 64%) more effective at AF than the GeForce 8800 GTX. (explain)

GeForce GTX 965M 60416 Mtexels/sec
GeForce 8800 GTX 36800 Mtexels/sec
Difference: 23616 (64%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 965M is a better choice, and very much so. (explain)

GeForce GTX 965M 30208 Mpixels/sec
GeForce 8800 GTX 13800 Mpixels/sec
Difference: 16408 (119%)

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.

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in MB per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR memory, it must 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, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in a 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 - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
