GeForce GTX 650 Ti 2GB vs Radeon RX 460

Intro

Compare all that to the Radeon RX 460, which features a clock speed of 1090 MHz and a GDDR5 memory frequency of 1750 MHz. It also features a 128-bit bus, and makes use of a 14 nm design. It is comprised of 896 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460		75 Watts
GeForce GTX 650 Ti 2GB		110 Watts
	Difference: 35 Watts (47%)

Memory Bandwidth

Performance-wise, the Radeon RX 460 should in theory be a lot superior to the GeForce GTX 650 Ti 2GB overall. (explain)

Radeon RX 460		112000 MB/sec
GeForce GTX 650 Ti 2GB		86400 MB/sec
	Difference: 25600 (30%)

Texel Rate

The Radeon RX 460 is a small bit (more or less 3%) better at anisotropic filtering than the GeForce GTX 650 Ti 2GB. (explain)

Radeon RX 460		61040 Mtexels/sec
GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
	Difference: 1648 (3%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 460 is the winner, though only just barely. (explain)

Radeon RX 460		17440 Mpixels/sec
GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
	Difference: 2592 (17%)

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 max amount of information (counted in megabytes per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units by the core clock 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines 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 fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
