GeForce GTS 150 vs Radeon RX 460

Intro

Compare those specs to the Radeon RX 460, which comes with GPU clock speed of 1090 MHz, and 4096 MB of GDDR5 memory set to run at 1750 MHz through a 128-bit bus. It also is made up of 896 Stream Processors, 56 TAUs, and 16 Raster Operation Units.

Radeon RX 460		75 Watts
GeForce GTS 150		141 Watts
	Difference: 66 Watts (88%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 460 will be 250% quicker than the GeForce GTS 150 overall, due to its higher data rate. (explain)

Radeon RX 460		112000 MB/sec
GeForce GTS 150		32000 MB/sec
	Difference: 80000 (250%)

Texel Rate

The Radeon RX 460 should be much (more or less 29%) faster with regards to texture filtering than the GeForce GTS 150. (explain)

Radeon RX 460		61040 Mtexels/sec
GeForce GTS 150		47360 Mtexels/sec
	Difference: 13680 (29%)

Pixel Rate

The Radeon RX 460 should be much (more or less 47%) faster with regards to anti-aliasing than the GeForce GTS 150, and should be able to handle higher screen resolutions while still performing well. (explain)

Radeon RX 460		17440 Mpixels/sec
GeForce GTS 150		11840 Mpixels/sec
	Difference: 5600 (47%)

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 (in units of megabytes per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, the result should 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 AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling 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 can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
