GeForce GTX 460 2GB vs Radeon RX 550

Intro

The GeForce GTX 460 2GB features a core clock speed of 675 MHz and a GDDR5 memory speed of 900 MHz. It also uses a 256-bit bus, and makes use of a 40 nm design. It is made up of 336 SPUs, 56 TAUs, and 32 Raster Operation Units.

Compare those specifications to the Radeon RX 550, which has GPU clock speed of 1100 MHz, and 2048 MB of GDDR5 RAM running at 1750 MHz through a 128-bit bus. It also is comprised of 512 Stream Processors, 32 TAUs, and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 amount of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the 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 maximum amount of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output 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 reach the max fill rate.
