GeForce GTX 860M vs Radeon R5 M330

Intro

Compare all of that to the Radeon R5 M330, which features GPU clock speed of 1030 MHz, and 2048 MB of DDR3 memory set to run at 900 MHz through a 64-bit bus. It also is made up of 320 SPUs, 20 TAUs, and 8 Raster Operation Units.

The GeForce GTX 860M is a lot (approximately 271%) more effective at texture filtering than the Radeon R5 M330. (explain)

GeForce GTX 860M		76512 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 55912 (271%)

Pixel Rate

The GeForce GTX 860M should be a lot (about 55%) better at AA than the Radeon R5 M330, and also will be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 860M		12752 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 4512 (55%)

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 data (counted in megabytes per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
