GeForce GT 450 (OEM) vs Radeon RX 460

Intro

The GeForce GT 450 (OEM) uses a 40 nm design. nVidia has clocked the core frequency at 790 MHz. The GDDR5 RAM is set to run at a frequency of 1000 MHz on this particular model. It features 144 SPUs along with 24 Texture Address Units and 24 ROPs.

Compare all that to the Radeon RX 460, which has a core clock frequency of 1090 MHz and a GDDR5 memory speed of 1750 MHz. It also uses a 128-bit bus, and uses a 14 nm design. It is made up of 896 SPUs, 56 TAUs, and 16 ROPs.

Memory Bandwidth: Bandwidth is the max amount of information (measured in MB per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 number of texture map elements (texels) that are applied per second. This number 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 video card will be at handling 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 card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's 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 rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
