GeForce GTS 450 1GB vs Radeon HD 6670 (OEM)
Intro
The GeForce GTS 450 1GB has a core clock speed of 783 MHz and a GDDR5 memory frequency of 902 MHz. It also features a 128-bit memory bus, and makes use of a 40 nm design. It is made up of 192 SPUs, 32 TAUs, and 16 ROPs.Compare all that to the Radeon HD 6670 (OEM), which makes use of a 40 nm design. AMD has set the core speed at 800 MHz. The GDDR5 RAM works at a speed of 1000 MHz on this card. It features 480 SPUs along with 24 TAUs and 8 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better 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 most pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core 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 fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
