GeForce GTX 970M vs Radeon R5 M330

Intro

Compare all that to the Radeon R5 M330, which has core clock speeds of 1030 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 RAM. It features 320 SPUs along with 20 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 970M should be a lot faster than the Radeon R5 M330 in general. (explain)

GeForce GTX 970M		96000 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 81600 (567%)

Texel Rate

The GeForce GTX 970M should be quite a bit (approximately 259%) more effective at AF than the Radeon R5 M330. (explain)

GeForce GTX 970M		73920 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 53320 (259%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 970M is superior to the Radeon R5 M330, by far. (explain)

GeForce GTX 970M		44352 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 36112 (438%)

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 megabytes per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 can be processed per second. This is worked out by multiplying the total number of texture units of the card by the core clock 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 applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its 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 speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
