GeForce GT 450 (OEM) vs Radeon RX 460 2GB

Intro

The GeForce GT 450 (OEM) comes with a clock frequency of 790 MHz and a GDDR5 memory speed of 1000 MHz. It also makes use of a 192-bit memory bus, and makes use of a 40 nm design. It features 144 SPUs, 24 Texture Address Units, and 24 ROPs.

Compare those specs to the Radeon RX 460 2GB, which uses a 14 nm design. AMD has clocked the core speed at 1090 MHz. The GDDR5 memory runs at a frequency of 1750 MHz on this specific model. It features 896 SPUs along with 56 TAUs and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the 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 maximum amount of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
