GeForce GTX 285 1GB vs Radeon R5 M330

Intro

Compare all of that to the Radeon R5 M330, which has a GPU core clock speed of 1030 MHz, and 2048 MB of DDR3 RAM running at 900 MHz through a 64-bit bus. It also features 320 SPUs, 20 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 285 1GB will be 1004% quicker than the Radeon R5 M330 overall, because of its higher bandwidth. (explain)

GeForce GTX 285 1GB		158976 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 144576 (1004%)

Texel Rate

The GeForce GTX 285 1GB should be quite a bit (about 152%) more effective at texture filtering than the Radeon R5 M330. (explain)

GeForce GTX 285 1GB		51840 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 31240 (152%)

Pixel Rate

The GeForce GTX 285 1GB is much (more or less 152%) more effective at anti-aliasing than the Radeon R5 M330, and also able to handle higher resolutions more effectively. (explain)

GeForce GTX 285 1GB		20736 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 12496 (152%)

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 maximum amount of data (in units of megabytes per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, 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 amount of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in a 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 - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
