GeForce GT 430 (OEM) vs Radeon R7 250

Intro

Compare all of that to the Radeon R7 250, which makes use of a 28 nm design. AMD has clocked the core speed at 1000 MHz. The GDDR5 RAM works at a frequency of 1150 MHz on this specific card. It features 384 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

GeForce GT 430 (OEM)		60 Watts
Radeon R7 250		65 Watts
	Difference: 5 Watts (8%)

Memory Bandwidth

Theoretically speaking, the Radeon R7 250 is 156% quicker than the GeForce GT 430 (OEM) overall, because of its higher bandwidth. (explain)

Radeon R7 250		73600 MB/sec
GeForce GT 430 (OEM)		28800 MB/sec
	Difference: 44800 (156%)

Texel Rate

The Radeon R7 250 will be much (about 114%) better at AF than the GeForce GT 430 (OEM). (explain)

Radeon R7 250		24000 Mtexels/sec
GeForce GT 430 (OEM)		11200 Mtexels/sec
	Difference: 12800 (114%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R7 250 is the winner, by far. (explain)

Radeon R7 250		8000 Mpixels/sec
GeForce GT 430 (OEM)		2800 Mpixels/sec
	Difference: 5200 (186%)

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 information (measured in megabytes per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total number of texture units by the core clock 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 processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs 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 output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
