GeForce GTX 465 vs GeForce GTX 980

Intro

The GeForce GTX 465 makes use of a 40 nm design. nVidia has clocked the core frequency at 607 MHz. The GDDR5 RAM is set to run at a speed of 802 MHz on this particular model. It features 352 SPUs along with 44 Texture Address Units and 32 ROPs.

Compare all of that to the GeForce GTX 980, which has core speeds of 1126 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 RAM. It features 2048 SPUs along with 128 Texture Address Units and 64 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 number of 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 processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. 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 many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
