GeForce GTX 275 vs Radeon RX 560

Intro

Compare all of that to the Radeon RX 560, which uses a 14 nm design. AMD has clocked the core frequency at 1175 MHz. The GDDR5 memory is set to run at a speed of 1750 MHz on this card. It features 1024 SPUs along with 64 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 560		80 Watts
GeForce GTX 275		219 Watts
	Difference: 139 Watts (174%)

Memory Bandwidth

Theoretically, the GeForce GTX 275 should be a small bit faster than the Radeon RX 560 in general. (explain)

GeForce GTX 275		127008 MB/sec
Radeon RX 560		114688 MB/sec
	Difference: 12320 (11%)

Texel Rate

The Radeon RX 560 is a lot (approximately 48%) more effective at AF than the GeForce GTX 275. (explain)

Radeon RX 560		75200 Mtexels/sec
GeForce GTX 275		50640 Mtexels/sec
	Difference: 24560 (48%)

Pixel Rate

The Radeon RX 560 should be a bit (more or less 6%) faster with regards to anti-aliasing than the GeForce GTX 275, and will be capable of handling higher resolutions while still performing well. (explain)

Radeon RX 560		18800 Mpixels/sec
GeForce GTX 275		17724 Mpixels/sec
	Difference: 1076 (6%)

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 largest amount of data (counted in MB per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated 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 drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
