GeForce GT 210 vs Radeon R7 250

Intro

Compare that to the Radeon R7 250, which uses a 28 nm design. AMD has set the core frequency at 1000 MHz. The GDDR5 RAM works at a speed of 1150 MHz on this particular model. It features 384 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

GeForce GT 210		31 Watts
Radeon R7 250		65 Watts
	Difference: 34 Watts (110%)

Memory Bandwidth

Performance-wise, the Radeon R7 250 should theoretically be quite a bit better than the GeForce GT 210 in general. (explain)

Radeon R7 250		73600 MB/sec
GeForce GT 210		12800 MB/sec
	Difference: 60800 (475%)

Texel Rate

The Radeon R7 250 should be a lot (about 409%) better at texture filtering than the GeForce GT 210. (explain)

Radeon R7 250		24000 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 19288 (409%)

Pixel Rate

The Radeon R7 250 is quite a bit (approximately 240%) faster with regards to anti-aliasing than the GeForce GT 210, and also should be able to handle higher screen resolutions more effectively. (explain)

Radeon R7 250		8000 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 5644 (240%)

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 information (measured in megabytes per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
