Radeon R9 M265X vs Radeon RX 460 2GB

Intro

Compare those specifications to the Radeon RX 460 2GB, which comes with a GPU core clock speed of 1090 MHz, and 2048 MB of GDDR5 memory running at 1750 MHz through a 128-bit bus. It also is made up of 896 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon RX 460 2GB should perform a lot faster than the Radeon R9 M265X overall. (explain)

Radeon RX 460 2GB		112000 MB/sec
Radeon R9 M265X		72000 MB/sec
	Difference: 40000 (56%)

Texel Rate

The Radeon RX 460 2GB is quite a bit (about 165%) more effective at anisotropic filtering than the Radeon R9 M265X. (explain)

Radeon RX 460 2GB		61040 Mtexels/sec
Radeon R9 M265X		23000 Mtexels/sec
	Difference: 38040 (165%)

Pixel Rate

The Radeon RX 460 2GB is quite a bit (about 90%) faster with regards to anti-aliasing than the Radeon R9 M265X, and also able to handle higher screen resolutions while still performing well. (explain)

Radeon RX 460 2GB		17440 Mpixels/sec
Radeon R9 M265X		9200 Mpixels/sec
	Difference: 8240 (90%)

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 max amount of data (in units of megabytes per second) that can be transported past the external memory interface in one 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, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount of texture units of the card by the core clock 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 processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its 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 card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
