GeForce GT 230 vs Radeon R7 250

Intro

Compare that to the Radeon R7 250, which comes with core clock speeds of 1000 MHz on the GPU, and 1150 MHz on the 1024 MB of GDDR5 RAM. It features 384 SPUs as well as 24 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Radeon R7 250 should in theory perform much faster than the GeForce GT 230 overall. (explain)

Radeon R7 250		73600 MB/sec
GeForce GT 230		38400 MB/sec
	Difference: 35200 (92%)

Texel Rate

The Radeon R7 250 is a lot (more or less 173%) more effective at AF than the GeForce GT 230. (explain)

Radeon R7 250		24000 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 15200 (173%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R7 250 is superior to the GeForce GT 230, by far. (explain)

Radeon R7 250		8000 Mpixels/sec
GeForce GT 230		4400 Mpixels/sec
	Difference: 3600 (82%)

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 maximum amount of information (measured in megabytes per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The figure 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 drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
