GeForce GTX 275 vs Radeon HD 6770 1GB

Intro

The GeForce GTX 275 features a core clock frequency of 633 MHz and a GDDR3 memory speed of 1134 MHz. It also makes use of a 448-bit bus, and makes use of a 55 nm design. It is made up of 240 SPUs, 80 Texture Address Units, and 28 Raster Operation Units.

Compare those specifications to the Radeon HD 6770 1GB, which uses a 40 nm design. AMD has clocked the core frequency at 900 MHz. The GDDR5 RAM runs at a speed of 1050 MHz on this particular model. It features 800 SPUs as well as 40 TAUs and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 are applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could 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 Raster Operations Pipelines 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 output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
