GeForce 930M vs Radeon R5 M330

Intro

Compare all of that to the Radeon R5 M330, which has a core clock speed of 1030 MHz and a DDR3 memory frequency of 900 MHz. It also features a 64-bit bus, and uses a 28 nm design. It features 320 SPUs, 20 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have the exact same bandwidth, so in theory they should perform the same. (explain)

Texel Rate

The GeForce 930M will be a small bit (approximately 8%) more effective at texture filtering than the Radeon R5 M330. (explain)

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

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R5 M330 is superior to the GeForce 930M, but it probably won't make a huge difference. (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 max amount of information (measured in megabytes per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, 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 figure is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
