GeForce GTS 150 vs Radeon RX 470

Intro

Compare those specs to the Radeon RX 470, which comes with a clock frequency of 926 MHz and a GDDR5 memory frequency of 1650 MHz. It also features a 256-bit bus, and makes use of a 14 nm design. It is comprised of 2048 SPUs, 128 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 470		120 Watts
GeForce GTS 150		141 Watts
	Difference: 21 Watts (18%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 470 will be 560% faster than the GeForce GTS 150 overall, because of its higher data rate. (explain)

Radeon RX 470		211200 MB/sec
GeForce GTS 150		32000 MB/sec
	Difference: 179200 (560%)

Texel Rate

The Radeon RX 470 will be quite a bit (about 150%) more effective at AF than the GeForce GTS 150. (explain)

Radeon RX 470		118528 Mtexels/sec
GeForce GTS 150		47360 Mtexels/sec
	Difference: 71168 (150%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 470 is a better choice, by far. (explain)

Radeon RX 470		29632 Mpixels/sec
GeForce GTS 150		11840 Mpixels/sec
	Difference: 17792 (150%)

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 (measured in megabytes per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the video 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 that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
