Radeon R5 M330 vs Radeon R9 M395X

Intro

The Radeon R5 M330 comes with core speeds of 1030 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 320 SPUs as well as 20 Texture Address Units and 8 Rasterization Operator Units.

Compare all of that to the Radeon R9 M395X, which has a clock speed of 723 MHz and a GDDR5 memory speed of 1250 MHz. It also uses a 256-bit bus, and makes use of a 28 nm design. It is comprised of 2048 SPUs, 128 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M395X should in theory be quite a bit superior to the Radeon R5 M330 overall. (explain)

Radeon R9 M395X 160000 MB/sec
Radeon R5 M330 14400 MB/sec
Difference: 145600 (1011%)

Texel Rate

The Radeon R9 M395X is a lot (about 349%) more effective at texture filtering than the Radeon R5 M330. (explain)

Radeon R9 M395X 92544 Mtexels/sec
Radeon R5 M330 20600 Mtexels/sec
Difference: 71944 (349%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 M395X is superior to the Radeon R5 M330, and very much so. (explain)

Radeon R9 M395X 23136 Mpixels/sec
Radeon R5 M330 8240 Mpixels/sec
Difference: 14896 (181%)

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 largest amount of data (in units of MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher 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 texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called 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 bandwidth is, the lower the ability to get to the max fill rate.
