GeForce GTX 1650 vs Radeon HD 5850

Intro

Compare those specs to the Radeon HD 5850, which has GPU clock speed of 725 MHz, and 1024 MB of GDDR5 RAM set to run at 1000 MHz through a 256-bit bus. It also is comprised of 1440(288x5) SPUs, 72 Texture Address Units, and 32 ROPs.

Radeon HD 5850		128000 MB/sec
	Difference: 3072 (2%)

Texel Rate

The GeForce GTX 1650 should be a lot (more or less 59%) faster with regards to AF than the Radeon HD 5850. (explain)

GeForce GTX 1650		83160 Mtexels/sec
Radeon HD 5850		52200 Mtexels/sec
	Difference: 30960 (59%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 1650 is the winner, by a large margin. (explain)

GeForce GTX 1650		47520 Mpixels/sec
Radeon HD 5850		23200 Mpixels/sec
	Difference: 24320 (105%)

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 (counted in megabytes per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel 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 ability to get to the max fill rate.
