GeForce GTX 460 (OEM) vs Radeon R5 M230

Intro

Compare those specifications to the Radeon R5 M230, which makes use of a 28 nm design. AMD has set the core speed at 780 MHz. The DDR3 RAM is set to run at a frequency of 1000 MHz on this particular card. It features 320 SPUs as well as 20 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 (OEM) should be 580% quicker than the Radeon R5 M230 overall, due to its higher data rate. (explain)

GeForce GTX 460 (OEM)		108800 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 92800 (580%)

Texel Rate

The GeForce GTX 460 (OEM) should be quite a bit (approximately 133%) better at AF than the Radeon R5 M230. (explain)

GeForce GTX 460 (OEM)		36400 Mtexels/sec
Radeon R5 M230		15600 Mtexels/sec
	Difference: 20800 (133%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 460 (OEM) is a better choice, by a large margin. (explain)

GeForce GTX 460 (OEM)		20800 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 17680 (567%)

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 max amount of information (in units of MB per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If 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 texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics 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 number of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
