GeForce GT 240 GDDR5 vs Radeon R5 M230

Intro

Compare that to the Radeon R5 M230, which features a core clock frequency of 780 MHz and a DDR3 memory speed of 1000 MHz. It also makes use of a 64-bit memory bus, and makes use of a 28 nm design. It is comprised of 320 SPUs, 20 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GT 240 GDDR5 should be a lot faster than the Radeon R5 M230 in general. (explain)

GeForce GT 240 GDDR5		54400 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 38400 (240%)

Texel Rate

The GeForce GT 240 GDDR5 should be a bit (approximately 13%) faster with regards to AF than the Radeon R5 M230. (explain)

GeForce GT 240 GDDR5		17600 Mtexels/sec
Radeon R5 M230		15600 Mtexels/sec
	Difference: 2000 (13%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GT 240 GDDR5 is a better choice, and very much so. (explain)

GeForce GT 240 GDDR5		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 maximum amount of information (counted in MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
