GeForce GT 340 1GB vs Radeon R5 M230

Intro

Compare that to the Radeon R5 M230, which features a clock frequency of 780 MHz and a DDR3 memory speed of 1000 MHz. It also uses a 64-bit memory bus, and uses a 28 nm design. It is made up of 320 SPUs, 20 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GT 340 1GB should be quite a bit faster than the Radeon R5 M230 in general. (explain)

GeForce GT 340 1GB		54400 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 38400 (240%)

Texel Rate

The GeForce GT 340 1GB should be a little bit (approximately 13%) better at texture filtering than the Radeon R5 M230. (explain)

GeForce GT 340 1GB		17600 Mtexels/sec
Radeon R5 M230		15600 Mtexels/sec
	Difference: 2000 (13%)

Pixel Rate

The GeForce GT 340 1GB will be quite a bit (more or less 41%) more effective at full screen anti-aliasing than the Radeon R5 M230, and will be able to handle higher screen resolutions more effectively. (explain)

GeForce GT 340 1GB		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 (measured in megabytes per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total number of texture units 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 one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
