VS

GeForce GTX 260 Core 216 vs Radeon HD 6450 (OEM) 1GB

Intro

The GeForce GTX 260 Core 216 has a clock frequency of 576 MHz and a GDDR3 memory speed of 999 MHz. It also features a 448-bit bus, and uses a 65 nm design. It is comprised of 216 SPUs, 72 Texture Address Units, and 28 Raster Operation Units.

Compare those specs to the Radeon HD 6450 (OEM) 1GB, which comes with GPU clock speed of 750 MHz, and 1024 MB of GDDR5 memory running at 900 MHz through a 64-bit bus. It also is comprised of 160 Stream Processors, 8 TAUs, and 4 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR type 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 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 in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the 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 maximum number of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
