GeForce GTX 460 1GB vs GeForce GTX 480
Intro
The GeForce GTX 460 1GB features a GPU clock speed of 675 MHz, and the 1024 MB of GDDR5 memory is set to run at 900 MHz through a 256-bit bus. It also is comprised of 336 Stream Processors, 56 Texture Address Units, and 32 ROPs.Compare those specs to the GeForce GTX 480, which has a clock frequency of 700 MHz and a GDDR5 memory frequency of 924 MHz. It also features a 384-bit bus, and uses a 40 nm design. It features 480 SPUs, 60 TAUs, and 48 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in 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 the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics card will be at 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 the video card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.

2 Responses to “GeForce GTX 460 1GB vs GeForce GTX 480”What card is above gtx 480?
That would depend on what you consider "above". The 580, 660 (maybe), 760, 6970, 7870, and likely 8770 when it comes out will be above it. Though some of that depends on what you are using it for, as I get better frames on a 480 than I ever did on my 6970s with Metro 2033.
