Radeon HD 5570 vs Radeon R5 M330

Intro

Compare those specifications to the Radeon R5 M330, which has a core clock speed of 1030 MHz and a DDR3 memory frequency of 900 MHz. It also uses a 64-bit memory bus, and makes use of a 28 nm design. It is comprised of 320 SPUs, 20 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 5570 should be 100% faster than the Radeon R5 M330 overall, due to its greater bandwidth. (explain)

Radeon HD 5570		28800 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 14400 (100%)

Texel Rate

The Radeon R5 M330 should be much (approximately 58%) more effective at anisotropic filtering than the Radeon HD 5570. (explain)

Radeon R5 M330		20600 Mtexels/sec
Radeon HD 5570		13000 Mtexels/sec
	Difference: 7600 (58%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R5 M330 is a better choice, and very much so. (explain)

Radeon R5 M330		8240 Mpixels/sec
Radeon HD 5570		5200 Mpixels/sec
	Difference: 3040 (58%)

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 information (measured in megabytes per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
