GeForce GTX 460 1GB vs Radeon HD 6870
Intro
The GeForce GTX 460 1GB makes use of a 40 nm design. nVidia has clocked the core frequency at 675 MHz. The GDDR5 memory is set to run at a frequency of 900 MHz on this specific model. It features 336 SPUs along with 56 Texture Address Units and 32 ROPs.Compare all that to the Radeon HD 6870, which comes with GPU clock 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 Stream Processors, 56 Texture Address Units, and 32 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher 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 amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock 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 fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum 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
