GeForce GT 1030 vs Radeon R9 270

Intro

Compare those specs to the Radeon R9 270, which features core clock speeds of 900 MHz on the GPU, and 1400 MHz on the 2048 MB of GDDR5 RAM. It features 1280 SPUs along with 80 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 1030		30 Watts
Radeon R9 270		150 Watts
	Difference: 120 Watts (400%)

Memory Bandwidth

Theoretically, the Radeon R9 270 should perform quite a bit faster than the GeForce GT 1030 overall. (explain)

Radeon R9 270		179200 MB/sec
GeForce GT 1030		49152 MB/sec
	Difference: 130048 (265%)

Texel Rate

The Radeon R9 270 will be a lot (about 78%) better at AF than the GeForce GT 1030. (explain)

Radeon R9 270		72000 Mtexels/sec
GeForce GT 1030		40480 Mtexels/sec
	Difference: 31520 (78%)

Pixel Rate

The Radeon R9 270 should be quite a bit (more or less 42%) better at anti-aliasing than the GeForce GT 1030, and also capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon R9 270		28800 Mpixels/sec
GeForce GT 1030		20240 Mpixels/sec
	Difference: 8560 (42%)

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 data (measured in megabytes per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. 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 lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
