GeForce GTX 460 SE vs GeForce GTX 970M

Intro

The GeForce GTX 460 SE makes use of a 40 nm design. nVidia has clocked the core speed at 650 MHz. The GDDR5 RAM is set to run at a frequency of 850 MHz on this specific model. It features 288 SPUs as well as 48 TAUs and 32 ROPs.

Compare that to the GeForce GTX 970M, which uses a 28 nm design. nVidia has clocked the core frequency at 924 MHz. The GDDR5 RAM is set to run at a frequency of 1000 MHz on this model. It features 1280 SPUs as well as 80 Texture Address Units and 48 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics 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 the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. 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.
