Radeon R5 M230 vs Radeon R5 M330

Intro

The Radeon R5 M230 features core clock speeds of 780 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 320 SPUs as well as 20 TAUs and 4 ROPs.

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R5 M230 should be just a bit faster 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 a lot (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

If running with a high screen resolution is important to you, then the Radeon R5 M330 is a better choice, by far. (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 maximum amount of data (in units of MB per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses 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 high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core 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 output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
