Radeon R5 M230 vs Radeon R5 M330

Intro

The Radeon R5 M230 makes use of a 28 nm design. AMD has set the core speed at 780 MHz. The DDR3 RAM is set to run at a frequency of 1000 MHz on this model. It features 320 SPUs as well as 20 TAUs and 4 Rasterization Operator Units.

Compare that to the Radeon R5 M330, which features a clock frequency of 1030 MHz and a DDR3 memory frequency of 900 MHz. It also uses a 64-bit bus, and uses a 28 nm design. It features 320 SPUs, 20 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R5 M230 should in theory be a little bit better than the Radeon R5 M330 in general. (explain)

Radeon R5 M230 16000 MB/sec
Radeon R5 M330 14400 MB/sec
Difference: 1600 (11%)

Texel Rate

The Radeon R5 M330 is much (about 32%) faster with regards to texture filtering than the Radeon R5 M230. (explain)

Radeon R5 M330 20600 Mtexels/sec
Radeon R5 M230 15600 Mtexels/sec
Difference: 5000 (32%)

Pixel Rate

The Radeon R5 M330 should be quite a bit (more or less 164%) faster with regards to full screen anti-aliasing than the Radeon R5 M230, and able to handle higher screen resolutions while still performing well. (explain)

Radeon R5 M330 8240 Mpixels/sec
Radeon R5 M230 3120 Mpixels/sec
Difference: 5120 (164%)

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: Memory bandwidth is the max amount of data (counted in MB per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. 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 many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
