GeForce GT 450 (OEM) vs Radeon R9 M280X

Intro

The GeForce GT 450 (OEM) features core speeds of 790 MHz on the GPU, and 1000 MHz on the 1536 MB of GDDR5 RAM. It features 144 SPUs as well as 24 Texture Address Units and 24 Rasterization Operator Units.

Compare that to the Radeon R9 M280X, which has GPU clock speed of 900 MHz, and 4096 MB of GDDR5 RAM set to run at 1375 MHz through a 128-bit bus. It also is comprised of 896 Stream Processors, 56 TAUs, and 16 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure 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 output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
