GeForce GT 230 vs Radeon R7 M265

Intro

Compare that to the Radeon R7 M265, which comes with GPU core speed of 725 MHz, and 2048 MB of DDR3 memory set to run at 1000 MHz through a 128-bit bus. It also is made up of 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce GT 230 should perform a small bit faster than the Radeon R7 M265 overall. (explain)

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

Texel Rate

The Radeon R7 M265 should be much (more or less 98%) more effective at 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 a lot (approximately 32%) better at AA than the GeForce GT 230, and will be 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: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If 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 texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, 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 that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
