GeForce 810M vs Radeon R5 M330

Intro

Compare those specs to the Radeon R5 M330, which features a core clock frequency of 1030 MHz and a DDR3 memory speed of 900 MHz. It also makes use of a 64-bit bus, and uses a 28 nm design. It features 320 SPUs, 20 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

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

Texel Rate

The Radeon R5 M330 should be much (about 249%) more effective at anisotropic filtering than the GeForce 810M. (explain)

Radeon R5 M330		20600 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 14696 (249%)

Pixel Rate

The Radeon R5 M330 should be much (more or less 179%) more effective at full screen anti-aliasing than the GeForce 810M, and also able to handle higher resolutions better. (explain)

Radeon R5 M330		8240 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 5288 (179%)

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 maximum amount of data (measured in MB per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock 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 in one second.

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