GeForce GTX 465 vs GeForce GTX 880M

Intro

The GeForce GTX 465 has a core clock speed of 607 MHz and a GDDR5 memory frequency of 802 MHz. It also features a 256-bit memory bus, and uses a 40 nm design. It is comprised of 352 SPUs, 44 TAUs, and 32 Raster Operation Units.

Compare all of that to the GeForce GTX 880M, which comes with core speeds of 954 MHz on the GPU, and 1000 MHz on the 4096 MB of GDDR5 RAM. It features 1536 SPUs along with 128 Texture Address Units and 32 ROPs.

Memory Bandwidth: Bandwidth is the max amount of information (counted in megabytes per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it should 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 AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is worked out by multiplying the total number of texture units of the card by the core 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 amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
