Radeon HD 4830 512MB vs Radeon R5 M330

Intro

The Radeon HD 4830 512MB uses a 55 nm design. AMD has set the core speed at 575 MHz. The GDDR3 RAM works at a speed of 900 MHz on this specific card. It features 640(128x5) SPUs as well as 32 TAUs and 16 ROPs.

Compare all of that to the Radeon R5 M330, which has a core clock speed of 1030 MHz and a DDR3 memory speed of 900 MHz. It also features a 64-bit memory bus, and uses a 28 nm design. It is made up of 320 SPUs, 20 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon HD 4830 512MB should in theory be a lot better than the Radeon R5 M330 in general. (explain)

Radeon HD 4830 512MB 57600 MB/sec
Radeon R5 M330 14400 MB/sec
Difference: 43200 (300%)

Texel Rate

The Radeon R5 M330 should be a small bit (approximately 12%) more effective at anisotropic filtering than the Radeon HD 4830 512MB. (explain)

Radeon R5 M330 20600 Mtexels/sec
Radeon HD 4830 512MB 18400 Mtexels/sec
Difference: 2200 (12%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 4830 512MB is superior to the Radeon R5 M330, though only just barely. (explain)

Radeon HD 4830 512MB 9200 Mpixels/sec
Radeon R5 M330 8240 Mpixels/sec
Difference: 960 (12%)

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.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's 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 calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the 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 that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
