GeForce GT 130 vs Radeon HD 6450 (OEM)

Intro

The GeForce GT 130 features core clock speeds of 500 MHz on the GPU, and 250 MHz on the 768 MB of DDR2 RAM. It features 48 SPUs along with 24 Texture Address Units and 16 ROPs.

Compare those specifications to the Radeon HD 6450 (OEM), which has a GPU core clock speed of 625 MHz, and 512 MB of GDDR3 memory running at 800 MHz through a 64-bit bus. It also is comprised of 160 Stream Processors, 8 Texture Address Units, and 4 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 number of texture units by the core speed of the chip. The higher this number, the better the graphics 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 the graphics 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 amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
