GeForce GTX 460 (OEM) vs Radeon HD 5750 1GB

Intro

The GeForce GTX 460 (OEM) makes use of a 40 nm design. nVidia has clocked the core speed at 650 MHz. The GDDR5 memory works at a frequency of 850 MHz on this particular card. It features 336 SPUs along with 56 Texture Address Units and 32 Rasterization Operator Units.

Compare those specifications to the Radeon HD 5750 1GB, which makes use of a 40 nm design. AMD has set the core speed at 700 MHz. The GDDR5 memory runs at a frequency of 1150 MHz on this specific card. It features 720(144x5) SPUs along with 36 TAUs and 16 Rasterization Operator Units.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling 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 video card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
