Radeon R5 M330 vs Radeon R7 240

Intro

Compare that to the Radeon R7 240, which uses a 28 nm design. AMD has set the core frequency at 730 MHz. The DDR3 memory runs at a speed of 900 MHz on this model. It features 320 SPUs as well as 20 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R7 240 should perform much faster than the Radeon R5 M330 in general. (explain)

Radeon R7 240		28800 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 14400 (100%)

Texel Rate

The Radeon R5 M330 should be quite a bit (about 41%) more effective at AF than the Radeon R7 240. (explain)

Radeon R5 M330		20600 Mtexels/sec
Radeon R7 240		14600 Mtexels/sec
	Difference: 6000 (41%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R5 M330 is a better choice, by far. (explain)

Radeon R5 M330		8240 Mpixels/sec
Radeon R7 240		5840 Mpixels/sec
	Difference: 2400 (41%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better 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 are applied in one second. This figure 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel 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.
