GeForce GTX 750 Ti vs Radeon RX 590

Intro

Compare those specifications to the Radeon RX 590, which has clock speeds of 1469 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 memory. It features 2304 SPUs as well as 144 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750 Ti		60 Watts
Radeon RX 590		175 Watts
	Difference: 115 Watts (192%)

Memory Bandwidth

The Radeon RX 590, in theory, should perform quite a bit faster than the GeForce GTX 750 Ti overall. (explain)

Radeon RX 590		262144 MB/sec
GeForce GTX 750 Ti		86400 MB/sec
	Difference: 175744 (203%)

Texel Rate

The Radeon RX 590 is a lot (about 418%) faster with regards to AF than the GeForce GTX 750 Ti. (explain)

Radeon RX 590		211536 Mtexels/sec
GeForce GTX 750 Ti		40800 Mtexels/sec
	Difference: 170736 (418%)

Pixel Rate

The Radeon RX 590 will be quite a bit (more or less 188%) better at full screen anti-aliasing than the GeForce GTX 750 Ti, and should be capable of handling higher screen resolutions more effectively. (explain)

Radeon RX 590		47008 Mpixels/sec
GeForce GTX 750 Ti		16320 Mpixels/sec
	Difference: 30688 (188%)

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: Memory bandwidth is the max amount of information (in units of MB per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 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 texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel 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 max fill rate.
