Radeon HD 5750 1GB vs Radeon R5 M330

Intro

Compare all of that to the Radeon R5 M330, which has a clock frequency of 1030 MHz and a DDR3 memory frequency of 900 MHz. It also makes use of a 64-bit memory bus, and makes use of a 28 nm design. It features 320 SPUs, 20 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 5750 1GB is 411% quicker than the Radeon R5 M330 overall, because of its greater data rate. (explain)

Radeon HD 5750 1GB		73600 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 59200 (411%)

Texel Rate

The Radeon HD 5750 1GB should be much (more or less 22%) more effective at texture filtering than the Radeon R5 M330. (explain)

Radeon HD 5750 1GB		25200 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 4600 (22%)

Pixel Rate

The Radeon HD 5750 1GB should be a lot (approximately 36%) more effective at AA than the Radeon R5 M330, and also should be able to handle higher resolutions without slowing down too much. (explain)

Radeon HD 5750 1GB		11200 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 2960 (36%)

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 max amount of data (measured in MB 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. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour 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 output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
