GeForce GTX 580 vs GeForce GTX 980

Intro

The GeForce GTX 580 uses a 40 nm design. nVidia has clocked the core speed at 772 MHz. The GDDR5 memory runs at a frequency of 1002 MHz on this particular model. It features 512 SPUs as well as 64 Texture Address Units and 48 Rasterization Operator Units.

Compare all that to the GeForce GTX 980, which features a clock speed of 1126 MHz and a GDDR5 memory speed of 1750 MHz. It also makes use of a 256-bit bus, and makes use of a 28 nm design. It features 2048 SPUs, 128 TAUs, and 64 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.

looks like the bus width data has been reversed, 384 vs 256
