GeForce GTX 460 SE vs Radeon RX 460

Intro

The GeForce GTX 460 SE has a GPU clock speed of 650 MHz, and the 1024 MB of GDDR5 memory is set to run at 850 MHz through a 256-bit bus. It also is comprised of 288 Stream Processors, 48 Texture Address Units, and 32 Raster Operation Units.

Compare those specs to the Radeon RX 460, which features a core clock frequency of 1090 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 128-bit bus, and makes use of a 14 nm design. It features 896 SPUs, 56 Texture Address Units, and 16 ROPs.

Memory Bandwidth: Bandwidth is the max amount of information (measured in megabytes per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
