Radeon R5 M330 vs Radeon R9 M295X

Intro

Compare all that to the Radeon R9 M295X, which comes with GPU core speed of 750 MHz, and 4096 MB of GDDR5 RAM running at 1375 MHz through a 256-bit bus. It also features 2048 Stream Processors, 128 TAUs, and 32 ROPs.

Radeon R5 M330		14400 MB/sec
	Difference: 161600 (1122%)

Texel Rate

The Radeon R9 M295X should be much (approximately 366%) better at texture filtering than the Radeon R5 M330. (explain)

Radeon R9 M295X		96000 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 75400 (366%)

Pixel Rate

The Radeon R9 M295X should be quite a bit (more or less 191%) better at FSAA than the Radeon R5 M330, and also able to handle higher screen resolutions more effectively. (explain)

Radeon R9 M295X		24000 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 15760 (191%)

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: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the 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 texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling 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 that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
