GeForce GTX 460 1GB vs Radeon HD 6870
Intro
The GeForce GTX 460 1GB uses a 40 nm design. nVidia has clocked the core speed at 675 MHz. The GDDR5 memory works at a frequency of 900 MHz on this particular model. It features 336 SPUs as well as 56 TAUs and 32 ROPs.Compare all of that to the Radeon HD 6870, which uses a 40 nm design. AMD has clocked the core frequency at 900 MHz. The GDDR5 memory is set to run at a frequency of 1050 MHz on this model. It features 1120 SPUs along with 56 TAUs and 32 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in MB per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record 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 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 output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach 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
