GeForce GTX 460 1GB vs GeForce GTX 480
Intro
The GeForce GTX 460 1GB features 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 GeForce GTX 480, which features core speeds of 700 MHz on the GPU, and 924 MHz on the 1536 MB of GDDR5 memory. It features 480 SPUs as well as 60 Texture Address Units and 48 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in MB per second) that can be moved 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 type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, 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 number of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount 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 is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max 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.
