GeForce GTX 965M vs Radeon R5 M330

Intro

Compare all that to the Radeon R5 M330, which comes with a GPU core clock speed of 1030 MHz, and 2048 MB of DDR3 memory running 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 965M should be quite a bit faster than the Radeon R5 M330 in general. (explain)

GeForce GTX 965M		64000 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 49600 (344%)

Texel Rate

The GeForce GTX 965M is a lot (about 193%) better at texture filtering than the Radeon R5 M330. (explain)

GeForce GTX 965M		60416 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 39816 (193%)

Pixel Rate

The GeForce GTX 965M should be quite a bit (approximately 267%) better at anti-aliasing than the Radeon R5 M330, and should be capable of handling higher resolutions while still performing well. (explain)

GeForce GTX 965M		30208 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 21968 (267%)

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 (measured in megabytes per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
