GeForce GTX 275 vs Radeon R5 M330

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 275 will be 782% faster than the Radeon R5 M330 in general, because of its higher data rate. (explain)

GeForce GTX 275		127008 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 112608 (782%)

Texel Rate

The GeForce GTX 275 should be quite a bit (approximately 146%) faster with regards to texture filtering than the Radeon R5 M330. (explain)

GeForce GTX 275		50640 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 30040 (146%)

Pixel Rate

The GeForce GTX 275 should be a lot (more or less 115%) more effective at AA than the Radeon R5 M330, and also will be capable of handling higher resolutions while still performing well. (explain)

GeForce GTX 275		17724 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 9484 (115%)

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 maximum amount of information (counted in megabytes per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, 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 amount of texture units by the core clock 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 a second.

Pixel Rate: Pixel rate is the maximum number of 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 calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
