GeForce GT 230 vs Radeon R7 M265

Intro

Compare all of that to the Radeon R7 M265, which comes with a GPU core clock speed of 725 MHz, and 2048 MB of DDR3 memory running at 1000 MHz through a 128-bit bus. It also is comprised of 384 SPUs, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GT 230 should theoretically perform a little bit faster than the Radeon R7 M265 in general. (explain)

GeForce GT 230		38400 MB/sec
Radeon R7 M265		32000 MB/sec
	Difference: 6400 (20%)

Texel Rate

The Radeon R7 M265 is a lot (more or less 98%) faster with regards to anisotropic filtering than the GeForce GT 230. (explain)

Radeon R7 M265		17400 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 8600 (98%)

Pixel Rate

The Radeon R7 M265 should be quite a bit (approximately 32%) faster with regards to anti-aliasing than the GeForce GT 230, and also able to handle higher screen resolutions more effectively. (explain)

Radeon R7 M265		5800 Mpixels/sec
GeForce GT 230		4400 Mpixels/sec
	Difference: 1400 (32%)

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 information (in units of megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better 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 number of texture map elements (texels) that can be applied per 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 higher this number, the better the card will be at 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 that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
