GeForce GT 230 vs Radeon R9 M265X

Intro

Compare that to the Radeon R9 M265X, which makes use of a 28 nm design. AMD has set the core speed at 575 MHz. The GDDR5 memory works at a frequency of 1125 MHz on this particular model. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M265X should be 88% faster than the GeForce GT 230 overall, because of its greater data rate. (explain)

Radeon R9 M265X		72000 MB/sec
GeForce GT 230		38400 MB/sec
	Difference: 33600 (88%)

Texel Rate

The Radeon R9 M265X should be quite a bit (more or less 161%) better at texture filtering than the GeForce GT 230. (explain)

Radeon R9 M265X		23000 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 14200 (161%)

Pixel Rate

The Radeon R9 M265X will be much (approximately 109%) more effective at anti-aliasing than the GeForce GT 230, and also should be capable of handling higher screen resolutions more effectively. (explain)

Radeon R9 M265X		9200 Mpixels/sec
GeForce GT 230		4400 Mpixels/sec
	Difference: 4800 (109%)

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 (measured in megabytes per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one 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 the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
