GeForce GTX 465 vs Radeon RX 560

Intro

Compare those specifications to the Radeon RX 560, which features a core clock frequency of 1175 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 features 1024 SPUs, 64 TAUs, and 16 ROPs.

Radeon RX 560		80 Watts
GeForce GTX 465		200 Watts
	Difference: 120 Watts (150%)

Memory Bandwidth

As far as performance goes, the Radeon RX 560 should in theory be a little bit superior to the GeForce GTX 465 overall. (explain)

Radeon RX 560		114688 MB/sec
GeForce GTX 465		102592 MB/sec
	Difference: 12096 (12%)

Texel Rate

The Radeon RX 560 will be a lot (approximately 182%) better at texture filtering than the GeForce GTX 465. (explain)

Radeon RX 560		75200 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 48492 (182%)

Pixel Rate

The GeForce GTX 465 should be just a bit (approximately 3%) faster with regards to AA than the Radeon RX 560, and should be capable of handling higher resolutions while still performing well. (explain)

GeForce GTX 465		19424 Mpixels/sec
Radeon RX 560		18800 Mpixels/sec
	Difference: 624 (3%)

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 data (measured in MB per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
