GeForce GT 130 vs Radeon R9 M390X

Intro

Compare that to the Radeon R9 M390X, which features GPU core speed of 723 MHz, and 4096 MB of GDDR5 RAM set to run at 1250 MHz through a 256-bit bus. It also is made up of 2048 Stream Processors, 128 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 130		75 Watts
Radeon R9 M390X		125 Watts
	Difference: 50 Watts (67%)

Memory Bandwidth

In theory, the Radeon R9 M390X should be 1233% quicker than the GeForce GT 130 overall, due to its higher bandwidth. (explain)

Radeon R9 M390X		160000 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 148000 (1233%)

Texel Rate

The Radeon R9 M390X is a lot (approximately 671%) more effective at AF than the GeForce GT 130. (explain)

Radeon R9 M390X		92544 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 80544 (671%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M390X is superior to the GeForce GT 130, and very much so. (explain)

Radeon R9 M390X		23136 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 15136 (189%)

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 moved across the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 applied per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in one 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 speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
