GeForce GT 230 vs Radeon R7 370 4G

Intro

Compare those specs to the Radeon R7 370 4G, which uses a 28 nm design. AMD has set the core frequency at 975 MHz. The GDDR5 RAM works at a frequency of 1400 MHz on this particular model. It features 1024 SPUs as well as 64 TAUs and 32 ROPs.

GeForce GT 230		65 Watts
Radeon R7 370 4G		110 Watts
	Difference: 45 Watts (69%)

Memory Bandwidth

Theoretically speaking, the Radeon R7 370 4G should be 367% faster than the GeForce GT 230 in general, due to its higher data rate. (explain)

Radeon R7 370 4G		179200 MB/sec
GeForce GT 230		38400 MB/sec
	Difference: 140800 (367%)

Texel Rate

The Radeon R7 370 4G will be quite a bit (approximately 609%) better at anisotropic filtering than the GeForce GT 230. (explain)

Radeon R7 370 4G		62400 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 53600 (609%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R7 370 4G is the winner, by a large margin. (explain)

Radeon R7 370 4G		31200 Mpixels/sec
GeForce GT 230		4400 Mpixels/sec
	Difference: 26800 (609%)

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 largest amount of data (counted in megabytes per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
