GeForce GT 230 vs Radeon R9 M375X

Intro

Compare all of that to the Radeon R9 M375X, which has a GPU core clock speed of 1015 MHz, and 4096 MB of GDDR5 RAM running at 1125 MHz through a 128-bit bus. It also features 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M375X should theoretically be quite a bit superior to the GeForce GT 230 overall. (explain)

Radeon R9 M375X		72000 MB/sec
GeForce GT 230		38400 MB/sec
	Difference: 33600 (88%)

Texel Rate

The Radeon R9 M375X is much (approximately 361%) better at AF than the GeForce GT 230. (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 31800 (361%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R9 M375X is the winner, by a large margin. (explain)

Radeon R9 M375X		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: Bandwidth is the max amount of information (in units of megabytes per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the 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 texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number of texture units 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 a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
