Radeon R5 M230 vs Radeon R5 M330

Intro

The Radeon R5 M230 uses a 28 nm design. AMD has clocked the core speed at 780 MHz. The DDR3 memory is set to run at a speed of 1000 MHz on this card. It features 320 SPUs along with 20 TAUs and 4 Rasterization Operator Units.

Compare all that to the Radeon R5 M330, which makes use of a 28 nm design. AMD has clocked the core speed at 1030 MHz. The DDR3 RAM runs at a speed of 900 MHz on this particular model. It features 320 SPUs as well as 20 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R5 M230 should theoretically be a bit superior to 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 will be quite a bit (approximately 32%) faster with regards to AF 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 much (more or less 164%) more effective at AA than the Radeon R5 M230, and also should be able to handle higher resolutions more effectively. (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: Bandwidth is the largest amount of information (counted in megabytes per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's 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 amount of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
