VS

GeForce 820M vs Radeon R5 M230

Intro

The GeForce 820M has a core clock frequency of 719 MHz and a DDR3 memory speed of 1000 MHz. It also features a 64-bit memory bus, and uses a 28 nm design. It is comprised of 96 SPUs, 16 Texture Address Units, and 4 Raster Operation Units.

Compare those specifications to the Radeon R5 M230, which uses a 28 nm design. AMD has set the core frequency at 780 MHz. The DDR3 RAM works at a speed of 1000 MHz on this particular model. It features 320 SPUs as well as 20 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

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

Texel Rate

The Radeon R5 M230 is much (about 36%) more effective at AF than the GeForce 820M. (explain)

Radeon R5 M230 15600 Mtexels/sec
GeForce 820M 11504 Mtexels/sec
Difference: 4096 (36%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R5 M230 is superior to the GeForce 820M, not by a very large margin though. (explain)

Radeon R5 M230 3120 Mpixels/sec
GeForce 820M 2876 Mpixels/sec
Difference: 244 (8%)

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 information (measured in megabytes per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen 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 texture units by the core speed of the chip. The higher the texel rate, the better the video 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 maximum amount of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
