GeForce GTX 460 1GB vs Radeon HD 6870
Intro
The GeForce GTX 460 1GB has a core clock frequency of 675 MHz and a GDDR5 memory frequency of 900 MHz. It also features a 256-bit bus, and uses a 40 nm design. It is comprised of 336 SPUs, 56 Texture Address Units, and 32 ROPs.Compare that to the Radeon HD 6870, which features GPU core speed of 900 MHz, and 1024 MB of GDDR5 RAM running at 1050 MHz through a 256-bit bus. It also is made up of 1120 SPUs, 56 TAUs, and 32 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in MB per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.

2 Responses to “GeForce GTX 460 1GB vs Radeon HD 6870”Am a fan of Nvdia graphic cards i have an old 1gb 9400gt and i was planing to upgrade to the high performance Gtx to 150£ MAX but since am in this WEBSITE I thing am buying an Ati card they have better performance an cheaper then the Nvdia so am thinking 6870 is my choice
