GeForce GTS 250 512MB vs Radeon HD 6670 (OEM)
Intro
The GeForce GTS 250 512MB uses a 65/55 nm design. nVidia has clocked the core frequency at 738 MHz. The GDDR3 memory runs at a frequency of 1100 MHz on this particular model. It features 128 SPUs as well as 64 TAUs and 16 Rasterization Operator Units.Compare those specs to the Radeon HD 6670 (OEM), which has a core clock frequency of 800 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 128-bit bus, and uses a 40 nm design. It is made up of 480 SPUs, 24 TAUs, and 8 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total amount 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 processed in one second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock 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 lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
