GeForce GT 230 vs Radeon R9 M375

Intro

Compare that to the Radeon R9 M375, which comes with a core clock frequency of 1015 MHz and a DDR3 memory speed of 1100 MHz. It also makes use of a 128-bit memory bus, and makes use of a 28 nm design. It features 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GT 230, in theory, should be a bit faster than the Radeon R9 M375 overall. (explain)

GeForce GT 230		38400 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 3200 (9%)

Texel Rate

The Radeon R9 M375 will be a lot (about 361%) more effective at AF than the GeForce GT 230. (explain)

Radeon R9 M375		40600 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 31800 (361%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 M375 is the winner, by a large margin. (explain)

Radeon R9 M375		16240 Mpixels/sec
GeForce GT 230		4400 Mpixels/sec
	Difference: 11840 (269%)

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 megabytes per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
