GeForce GT 1030 vs Radeon R7 250X

Intro

Compare all of that to the Radeon R7 250X, which comes with a GPU core clock speed of 1000 MHz, and 1024 MB of GDDR5 RAM running at 1125 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 1030		30 Watts
Radeon R7 250X		95 Watts
	Difference: 65 Watts (217%)

Memory Bandwidth

Theoretically speaking, the Radeon R7 250X will be 46% faster than the GeForce GT 1030 overall, because of its greater bandwidth. (explain)

Radeon R7 250X		72000 MB/sec
GeForce GT 1030		49152 MB/sec
	Difference: 22848 (46%)

Texel Rate

The GeForce GT 1030 is a little bit (approximately 1%) better at anisotropic filtering than the Radeon R7 250X. (explain)

GeForce GT 1030		40480 Mtexels/sec
Radeon R7 250X		40000 Mtexels/sec
	Difference: 480 (1%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GT 1030 is the winner, by far. (explain)

GeForce GT 1030		20240 Mpixels/sec
Radeon R7 250X		16000 Mpixels/sec
	Difference: 4240 (27%)

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 max amount of information (counted in megabytes per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is worked out 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
