GeForce 810M vs GeForce GTX 285 2GB

Intro

The GeForce 810M features a core clock frequency of 738 MHz and a DDR3 memory frequency of 900 MHz. It also features a 64-bit memory bus, and makes use of a 28 nm design. It is comprised of 48 SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Compare those specs to the GeForce GTX 285 2GB, which uses a 55 nm design. nVidia has set the core frequency at 648 MHz. The GDDR3 memory runs at a frequency of 1242 MHz on this specific model. It features 240 SPUs as well as 80 TAUs and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's 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 is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
