Radeon R5 M330 vs Radeon R9 280X

Intro

Compare all that to the Radeon R9 280X, which uses a 28 nm design. AMD has clocked the core speed at 850 MHz. The GDDR5 RAM is set to run at a frequency of 1500 MHz on this specific card. It features 2048 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 280X should be much faster than the Radeon R5 M330 in general. (explain)

Radeon R9 280X		288000 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 273600 (1900%)

Texel Rate

The Radeon R9 280X is quite a bit (about 428%) faster with regards to texture filtering than the Radeon R5 M330. (explain)

Radeon R9 280X		108800 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 88200 (428%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 280X is the winner, by far. (explain)

Radeon R9 280X		27200 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 18960 (230%)

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.

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
