GeForce GT 1030 vs Radeon R9 270

Intro

Compare those specifications to the Radeon R9 270, which uses a 28 nm design. AMD has set the core speed at 900 MHz. The GDDR5 memory runs at a speed of 1400 MHz on this specific card. It features 1280 SPUs as well as 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

Performance-wise, the Radeon R9 270 should in theory be quite a bit superior to the GeForce GT 1030 in general. (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 anisotropic filtering than the GeForce GT 1030. (explain)

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

Pixel Rate

If using a high resolution is important to you, then the Radeon R9 270 is a better choice, and very much so. (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: Bandwidth is the max amount of information (measured in megabytes per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR RAM, the result should 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 AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few 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.
