GeForce GTS 450 1GB vs Radeon RX 460

Intro

Compare all of that to the Radeon RX 460, which has core clock speeds of 1090 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 RAM. It features 896 SPUs as well as 56 Texture Address Units and 16 ROPs.

Radeon RX 460		75 Watts
GeForce GTS 450 1GB		106 Watts
	Difference: 31 Watts (41%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 460 should be 94% faster than the GeForce GTS 450 1GB in general, due to its higher bandwidth. (explain)

Radeon RX 460		112000 MB/sec
GeForce GTS 450 1GB		57728 MB/sec
	Difference: 54272 (94%)

Texel Rate

The Radeon RX 460 is quite a bit (approximately 144%) better at anisotropic filtering than the GeForce GTS 450 1GB. (explain)

Radeon RX 460		61040 Mtexels/sec
GeForce GTS 450 1GB		25056 Mtexels/sec
	Difference: 35984 (144%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 460 is the winner, by a large margin. (explain)

Radeon RX 460		17440 Mpixels/sec
GeForce GTS 450 1GB		12528 Mpixels/sec
	Difference: 4912 (39%)

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 largest amount of information (measured in MB per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics 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 most pixels the graphics card could 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 Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few 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.
