GeForce GT 450 (OEM) vs Radeon R9 M280X

Intro

The GeForce GT 450 (OEM) features a core clock speed of 790 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 192-bit bus, and makes use of a 40 nm design. It is made up of 144 SPUs, 24 TAUs, and 24 Raster Operation Units.

Compare those specifications to the Radeon R9 M280X, which uses a 28 nm design. AMD has set the core frequency at 900 MHz. The GDDR5 memory works at a speed of 1375 MHz on this particular card. It features 896 SPUs along with 56 TAUs and 16 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can 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 clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
