GeForce GTS 150 vs Radeon RX 460

Intro

Compare those specs to the Radeon RX 460, which uses a 14 nm design. AMD has clocked the core frequency at 1090 MHz. The GDDR5 memory runs at a speed of 1750 MHz on this particular card. It features 896 SPUs as well as 56 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

As far as performance goes, the Radeon RX 460 should in theory be quite a bit superior to the GeForce GTS 150 overall. (explain)

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

Texel Rate

The Radeon RX 460 will be a lot (about 29%) better at AF than the GeForce GTS 150. (explain)

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

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 460 is superior to the GeForce GTS 150, and very much so. (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 information (counted in megabytes per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units 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 applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs 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 is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
