GeForce 830M vs Radeon R5 M330

Intro

Compare those specifications to the Radeon R5 M330, which makes use of a 28 nm design. AMD has set the core frequency at 1030 MHz. The DDR3 RAM runs at a speed of 900 MHz on this specific card. It features 320 SPUs as well as 20 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

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

Texel Rate

The Radeon R5 M330 is a lot (about 25%) more effective at AF than the GeForce 830M. (explain)

Radeon R5 M330		20600 Mtexels/sec
GeForce 830M		16464 Mtexels/sec
	Difference: 4136 (25%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R5 M330 is superior to the GeForce 830M, but it probably won't make a huge difference. (explain)

Radeon R5 M330		8240 Mpixels/sec
GeForce 830M		8232 Mpixels/sec
	Difference: 8 (0%)

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 largest amount of data (measured in MB per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

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