GeForce 930M vs Radeon R5 M330

Intro

Compare those specifications to the Radeon R5 M330, which features 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 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so theoretically they should have identical performance. (explain)

Texel Rate

The GeForce 930M will be a bit (approximately 8%) better at AF than the Radeon R5 M330. (explain)

GeForce 930M		22272 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 1672 (8%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R5 M330 is the winner, not by a very large margin though. (explain)

Radeon R5 M330		8240 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 816 (11%)

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.

Price Comparison

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of MB 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 the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill 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 potential to reach the max fill rate.
