GeForce 930M vs Radeon R5 M330

Intro

Compare all that to the Radeon R5 M330, which makes use of a 28 nm design. AMD has clocked the core speed at 1030 MHz. The DDR3 memory works at a speed of 900 MHz on this model. It features 320 SPUs as well as 20 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

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

Texel Rate

The GeForce 930M is a bit (approximately 8%) faster with regards to AF than the Radeon R5 M330. (explain)

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

Pixel Rate

The Radeon R5 M330 should be a bit (about 11%) faster with regards to FSAA than the GeForce 930M, and also capable of handling higher screen resolutions without losing too much performance. (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: Bandwidth is the max amount of information (counted in megabytes per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 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 anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units 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 a second.

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