GeForce GT 230 vs Radeon R7 250

Intro

Compare all of that to the Radeon R7 250, which comes with a GPU core clock speed of 1000 MHz, and 1024 MB of GDDR5 RAM running at 1150 MHz through a 128-bit bus. It also is comprised of 384 Stream Processors, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Radeon R7 250, in theory, should be a lot faster than the GeForce GT 230 in general. (explain)

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

Texel Rate

The Radeon R7 250 is much (about 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

The Radeon R7 250 will be a lot (approximately 82%) faster with regards to anti-aliasing than the GeForce GT 230, and capable of handling higher screen resolutions better. (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 largest amount of data (counted in MB per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 are processed in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
