GeForce GT 340 vs Radeon R5 M230

Intro

Compare those specifications to the Radeon R5 M230, which features clock 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 340, in theory, should perform quite a bit faster than the Radeon R5 M230 overall. (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 (approximately 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 lots of anti-aliasing is important to you, then the GeForce GT 340 is the winner, by far. (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: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units by the core clock 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core 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 fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
