GeForce 8800 GTS (G80) 320MB vs GeForce GTX 965M

Intro

The GeForce 8800 GTS (G80) 320MB makes use of a 90 nm design. nVidia has set the core frequency at 513 MHz. The GDDR3 RAM runs at a frequency of 792 MHz on this particular model. It features 96 SPUs as well as 48 TAUs and 20 ROPs.

Compare those specifications to the GeForce GTX 965M, which makes use of a 28 nm design. nVidia has clocked the core frequency at 944 MHz. The GDDR5 RAM runs at a frequency of 1000 MHz on this particular model. It features 1024 SPUs as well as 64 TAUs and 32 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher 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 number of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock 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 rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
