GeForce GT 240 GDDR5 vs Radeon R5 M330

Intro

Compare those specs to the Radeon R5 M330, which comes with GPU core speed of 1030 MHz, and 2048 MB of DDR3 memory set to run at 900 MHz through a 64-bit bus. It also is comprised of 320 SPUs, 20 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GT 240 GDDR5, in theory, should be much faster than the Radeon R5 M330 overall. (explain)

GeForce GT 240 GDDR5		54400 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 40000 (278%)

Texel Rate

The Radeon R5 M330 should be a little bit (approximately 17%) better at AF than the GeForce GT 240 GDDR5. (explain)

Radeon R5 M330		20600 Mtexels/sec
GeForce GT 240 GDDR5		17600 Mtexels/sec
	Difference: 3000 (17%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R5 M330 is superior to the GeForce GT 240 GDDR5, by far. (explain)

Radeon R5 M330		8240 Mpixels/sec
GeForce GT 240 GDDR5		4400 Mpixels/sec
	Difference: 3840 (87%)

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 information (measured in MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

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