Radeon R5 M330 vs Radeon RX 460

Intro

Compare those specifications to the Radeon RX 460, which has a clock speed of 1090 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 128-bit bus, and makes use of a 14 nm design. It is made up of 896 SPUs, 56 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon RX 460 should theoretically be quite a bit superior to the Radeon R5 M330 in general. (explain)

Radeon RX 460		112000 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 97600 (678%)

Texel Rate

The Radeon RX 460 should be quite a bit (about 196%) more effective at texture filtering than the Radeon R5 M330. (explain)

Radeon RX 460		61040 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 40440 (196%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 460 is a better choice, by far. (explain)

Radeon RX 460		17440 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 9200 (112%)

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 maximum amount of data (in units of MB per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
