Radeon HD 7750 vs Radeon R5 M330

Intro

Compare those specifications to the Radeon R5 M330, which comes with a core clock speed of 1030 MHz and a DDR3 memory speed of 900 MHz. It also features a 64-bit bus, and makes use of a 28 nm design. It features 320 SPUs, 20 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon HD 7750 should in theory be much superior to the Radeon R5 M330 overall. (explain)

Radeon HD 7750		72000 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 57600 (400%)

Texel Rate

The Radeon HD 7750 should be quite a bit (about 24%) more effective at anisotropic filtering than the Radeon R5 M330. (explain)

Radeon HD 7750		25600 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 5000 (24%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 7750 is the winner, by a large margin. (explain)

Radeon HD 7750		12800 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 4560 (55%)

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 largest amount of information (measured in MB per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the 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 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 speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
