GeForce GTX 285 2GB vs GeForce GTX 880M

Intro

The GeForce GTX 285 2GB comes with core speeds of 648 MHz on the GPU, and 1242 MHz on the 2048 MB of GDDR3 RAM. It features 240 SPUs along with 80 Texture Address Units and 32 ROPs.

Compare that to the GeForce GTX 880M, which uses a 28 nm design. nVidia has set the core speed at 954 MHz. The GDDR5 RAM runs at a frequency of 1000 MHz on this model. It features 1536 SPUs along with 128 Texture Address Units and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high 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 texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can 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 Raster Operations Pipelines by the the core speed of the card. 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 many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
