GeForce GTX 460 1GB vs GeForce GTX 480
Intro
The GeForce GTX 460 1GB has a GPU core clock speed of 675 MHz, and the 1024 MB of GDDR5 RAM is set to run at 900 MHz through a 256-bit bus. It also is comprised of 336 SPUs, 56 Texture Address Units, and 32 ROPs.Compare those specifications to the GeForce GTX 480, which makes use of a 40 nm design. nVidia has clocked the core speed at 700 MHz. The GDDR5 memory works at a speed of 924 MHz on this specific model. It features 480 SPUs as well as 60 TAUs and 48 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of MB per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.

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.
