GeForce GTX 650 vs Radeon RX 590

Intro

Compare those specifications to the Radeon RX 590, which uses a 12 nm design. AMD has set the core frequency at 1469 MHz. The GDDR5 RAM is set to run at a speed of 2000 MHz on this specific card. It features 2304 SPUs as well as 144 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650		64 Watts
Radeon RX 590		175 Watts
	Difference: 111 Watts (173%)

Memory Bandwidth

As far as performance goes, the Radeon RX 590 should theoretically be a lot superior to the GeForce GTX 650 in general. (explain)

Radeon RX 590		262144 MB/sec
GeForce GTX 650		80000 MB/sec
	Difference: 182144 (228%)

Texel Rate

The Radeon RX 590 should be a lot (about 525%) more effective at texture filtering than the GeForce GTX 650. (explain)

Radeon RX 590		211536 Mtexels/sec
GeForce GTX 650		33856 Mtexels/sec
	Difference: 177680 (525%)

Pixel Rate

The Radeon RX 590 is quite a bit (about 178%) faster with regards to anti-aliasing than the GeForce GTX 650, and also will be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 590		47008 Mpixels/sec
GeForce GTX 650		16928 Mpixels/sec
	Difference: 30080 (178%)

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 largest amount of information (counted in MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of 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 number of 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 output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
