GeForce GT 340 vs Radeon R5 M230

Intro

Compare those specs to the Radeon R5 M230, which comes with a GPU core clock speed of 780 MHz, and 2048 MB of DDR3 memory running at 1000 MHz through a 64-bit bus. It also is made up of 320 Stream Processors, 20 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GT 340 should be 240% faster than the Radeon R5 M230 overall, because of its greater data rate. (explain)

GeForce GT 340		54400 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 38400 (240%)

Texel Rate

The GeForce GT 340 is a little bit (more or less 13%) faster with regards to anisotropic filtering than the Radeon R5 M230. (explain)

GeForce GT 340		17600 Mtexels/sec
Radeon R5 M230		15600 Mtexels/sec
	Difference: 2000 (13%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GT 340 is a better choice, by a large margin. (explain)

GeForce GT 340		4400 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 1280 (41%)

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 maximum amount of information (counted in MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
