GeForce GTX 650 vs Radeon RX 5600

Intro

Compare those specs to the Radeon RX 5600, which makes use of a 7 nm design. AMD has set the core speed at 1375 MHz. The GDDR6 memory works at a speed of 1500 MHz on this card. It features 2048 SPUs as well as 128 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650		64 Watts
Radeon RX 5600		150 Watts
	Difference: 86 Watts (134%)

Memory Bandwidth

In theory, the Radeon RX 5600 is 269% faster than the GeForce GTX 650 overall, due to its greater bandwidth. (explain)

Radeon RX 5600		294912 MB/sec
GeForce GTX 650		80000 MB/sec
	Difference: 214912 (269%)

Texel Rate

The Radeon RX 5600 will be much (more or less 420%) faster with regards to texture filtering than the GeForce GTX 650. (explain)

Radeon RX 5600		176000 Mtexels/sec
GeForce GTX 650		33856 Mtexels/sec
	Difference: 142144 (420%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 5600 is superior to the GeForce GTX 650, and very much so. (explain)

Radeon RX 5600		88000 Mpixels/sec
GeForce GTX 650		16928 Mpixels/sec
	Difference: 71072 (420%)

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 (in units of MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 most pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
