GeForce GTS 250 512MB vs Radeon HD 6670 (OEM)
Intro
The GeForce GTS 250 512MB uses a 65/55 nm design. nVidia has set the core frequency at 738 MHz. The GDDR3 RAM is set to run at a frequency of 1100 MHz on this particular model. It features 128 SPUs as well as 64 Texture Address Units and 16 ROPs.Compare those specs to the Radeon HD 6670 (OEM), which comes with core speeds of 800 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR5 RAM. It features 480 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 are processed in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
