GeForce GT 320 vs Radeon R5 M230

Intro

Compare that to the Radeon R5 M230, which features core speeds of 780 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 320 SPUs as well as 20 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GT 320 should theoretically perform much faster than the Radeon R5 M230 overall. (explain)

GeForce GT 320		25280 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 9280 (58%)

Texel Rate

The Radeon R5 M230 is just a bit (about 20%) better at AF than the GeForce GT 320. (explain)

Radeon R5 M230		15600 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 2640 (20%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GT 320 is the winner, by far. (explain)

GeForce GT 320		4320 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 1200 (38%)

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.

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 are applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, 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 number of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated 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 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 potential to reach the max fill rate.
