GeForce GTS 150 vs Radeon RX 570

Intro

Compare those specs to the Radeon RX 570, which has a core clock frequency of 1168 MHz and a GDDR5 memory speed of 1750 MHz. It also makes use of a 256-bit memory bus, and uses a 14 nm design. It is comprised of 2048 SPUs, 128 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTS 150		141 Watts
Radeon RX 570		150 Watts
	Difference: 9 Watts (6%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 570 will be 617% quicker than the GeForce GTS 150 in general, because of its greater data rate. (explain)

Radeon RX 570		229376 MB/sec
GeForce GTS 150		32000 MB/sec
	Difference: 197376 (617%)

Texel Rate

The Radeon RX 570 will be much (more or less 216%) more effective at texture filtering than the GeForce GTS 150. (explain)

Radeon RX 570		149504 Mtexels/sec
GeForce GTS 150		47360 Mtexels/sec
	Difference: 102144 (216%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 570 is the winner, by a large margin. (explain)

Radeon RX 570		37376 Mpixels/sec
GeForce GTS 150		11840 Mpixels/sec
	Difference: 25536 (216%)

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 data (in units of megabytes per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

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