VS

GeForce GTS 250 1GB vs Radeon HD 5670

Intro

The GeForce GTS 250 1GB comes with core clock speeds of 738 MHz on the GPU, and 1100 MHz on the 1024 MB of GDDR3 memory. It features 128 SPUs as well as 64 TAUs and 16 ROPs.

Compare that to the Radeon HD 5670, which makes use of a 40 nm design. ATi has clocked the core frequency at 775 MHz. The GDDR5 memory works at a frequency of 1000 MHz on this model. It features 400(80x5) SPUs along with 20 TAUs and 8 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the 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 number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total texture units by the core 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 applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
