GeForce GTS 450 vs Radeon HD 6750
Intro
The GeForce GTS 450 makes use of a 40 nm design. nVidia has clocked the core frequency at 783 MHz. The GDDR5 memory runs at a speed of 902 MHz on this model. It features 192 SPUs along with 32 TAUs and 16 ROPs.Compare those specifications to the Radeon HD 6750, which makes use of a 40 nm design. AMD has set the core frequency at 725 MHz. The GDDR5 RAM is set to run at a frequency of 1000 MHz on this card. It features 720 SPUs along with 36 Texture Address Units and 16 Rasterization Operator Units.

26100 Mtexels/sec |
| GeForce GTS 450 |
|
25056 Mtexels/sec |

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 can be processed per second. This is calculated 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 per second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out 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 rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
