GeForce GT 1030 vs Radeon R7 250X 2GB

Intro

Compare all of that to the Radeon R7 250X 2GB, which has a core clock speed of 1000 MHz and a GDDR5 memory frequency of 1125 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It features 640 SPUs, 40 Texture Address Units, and 16 ROPs.

The GeForce GT 1030 is a little bit (approximately 1%) more effective at AF than the Radeon R7 250X 2GB. (explain)

GeForce GT 1030		40480 Mtexels/sec
Radeon R7 250X 2GB		40000 Mtexels/sec
	Difference: 480 (1%)

Pixel Rate

The GeForce GT 1030 should be much (about 27%) better at FSAA than the Radeon R7 250X 2GB, and also able to handle higher screen resolutions more effectively. (explain)

GeForce GT 1030		20240 Mpixels/sec
Radeon R7 250X 2GB		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: Bandwidth is the max amount of information (counted in MB per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses 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 amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
