Radeon HD 5750 512MB vs Radeon R5 M330

Intro

Compare that to the Radeon R5 M330, which has GPU core speed of 1030 MHz, and 2048 MB of DDR3 memory running at 900 MHz through a 64-bit bus. It also is made up of 320 Stream Processors, 20 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 5750 512MB will be 411% quicker than the Radeon R5 M330 in general, due to its greater data rate. (explain)

Radeon HD 5750 512MB		73600 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 59200 (411%)

Texel Rate

The Radeon HD 5750 512MB is a lot (about 22%) more effective at AF than the Radeon R5 M330. (explain)

Radeon HD 5750 512MB		25200 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 4600 (22%)

Pixel Rate

The Radeon HD 5750 512MB should be quite a bit (approximately 36%) faster with regards to FSAA than the Radeon R5 M330, and should be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon HD 5750 512MB		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: Bandwidth is the max amount of data (measured in megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units 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 processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
