GeForce GTX 960 vs Radeon HD 5850

Intro

The GeForce GTX 960 features a GPU clock speed of 1127 MHz, and the 2048 MB of GDDR5 RAM runs at 1750 MHz through a 128-bit bus. It also is comprised of 1024 Stream Processors, 64 Texture Address Units, and 32 Raster Operation Units.

Compare those specs to the Radeon HD 5850, which has a clock speed of 725 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 256-bit memory bus, and makes use of a 40 nm design. It is comprised of 1440(288x5) SPUs, 72 TAUs, and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video 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 most pixels that the graphics card can 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 Render Output Units 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 rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
