GeForce GT 1030 vs Radeon R7 250X

Intro

Compare those specifications to the Radeon R7 250X, which features 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 SPUs, 40 TAUs, and 16 ROPs.

As far as performance goes, the Radeon R7 250X should in theory be a lot superior to the GeForce GT 1030 overall. (explain)

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

Texel Rate

The GeForce GT 1030 is a bit (approximately 1%) faster with regards to AF than the Radeon R7 250X. (explain)

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

Pixel Rate

The GeForce GT 1030 will be quite a bit (more or less 27%) better at FSAA than the Radeon R7 250X, and capable of handling higher resolutions while still performing well. (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: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen 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 number of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
