GeForce GTX 860M vs Radeon R5 M330

Intro

Compare those specs to the Radeon R5 M330, which comes with 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 is made up of 320 Stream Processors, 20 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 860M is 344% quicker than the Radeon R5 M330 overall, because of its greater data rate. (explain)

GeForce GTX 860M		64000 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 49600 (344%)

Texel Rate

The GeForce GTX 860M should be a lot (about 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

If using a high resolution is important to you, then the GeForce GTX 860M is the winner, and very much so. (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 largest amount of data (in units of MB per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses 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 high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
