GeForce GTX 460 2GB vs Radeon RX 460 2GB

Intro

Compare all that to the Radeon RX 460 2GB, which uses a 14 nm design. AMD has set the core frequency at 1090 MHz. The GDDR5 memory runs at a frequency of 1750 MHz on this model. It features 896 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.

Pixel Rate

The GeForce GTX 460 2GB is quite a bit (about 24%) better at FSAA than the Radeon RX 460 2GB, and also capable of handling higher resolutions while still performing well. (explain)

GeForce GTX 460 2GB		21600 Mpixels/sec
Radeon RX 460 2GB		17440 Mpixels/sec
	Difference: 4160 (24%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be transported past 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, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. 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 can be processed per second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the 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 most pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
