GeForce 830M vs Radeon R5 M330

Intro

The GeForce 830M uses a 28 nm design. nVidia has clocked the core speed at 1029 MHz. The DDR3 RAM runs at a speed of 900 MHz on this specific model. It features 256 SPUs as well as 16 TAUs and 8 Rasterization Operator Units.

Compare those specs to the Radeon R5 M330, which comes with clock speeds of 1030 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 RAM. It features 320 SPUs as well as 20 TAUs and 8 Rasterization Operator Units.

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 Radeon R5 M330 should be much (approximately 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 a high screen resolution is important to you, then the Radeon R5 M330 is superior to the GeForce 830M, though not by far. (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.

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in MB per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
