Radeon HD 5830 vs Radeon R5 M330

Intro

Compare that to the Radeon R5 M330, which makes use of a 28 nm design. AMD has clocked the core frequency at 1030 MHz. The DDR3 memory is set to run at a speed of 900 MHz on this particular model. It features 320 SPUs as well as 20 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon HD 5830 should theoretically be a lot better than the Radeon R5 M330 in general. (explain)

Radeon HD 5830		128000 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 113600 (789%)

Texel Rate

The Radeon HD 5830 should be quite a bit (more or less 117%) more effective at AF than the Radeon R5 M330. (explain)

Radeon HD 5830		44800 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 24200 (117%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon HD 5830 is superior to the Radeon R5 M330, by a large margin. (explain)

Radeon HD 5830		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: Memory bandwidth is the max amount of information (counted in MB per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If 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 higher screen 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 texture units by the core speed of the chip. The higher this number, the better the graphics 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 number of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
