GeForce GTX 460 1GB vs GeForce GTX 480
Intro
The GeForce GTX 460 1GB has a GPU clock speed of 675 MHz, and the 1024 MB of GDDR5 RAM runs at 900 MHz through a 256-bit bus. It also is made up of 336 Stream Processors, 56 Texture Address Units, and 32 ROPs.Compare those specs to the GeForce GTX 480, which uses a 40 nm design. nVidia has clocked the core speed at 700 MHz. The GDDR5 RAM is set to run at a speed of 924 MHz on this specific card. It features 480 SPUs as well as 60 TAUs and 48 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in MB per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 can be applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the 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 most pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability 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.
