GeForce GTX 1650 vs Radeon HD 3850 1GB

Intro

Compare those specs to the Radeon HD 3850 1GB, which has a core clock frequency of 668 MHz and a GDDR3 memory frequency of 828 MHz. It also uses a 256-bit memory bus, and uses a 55 nm design. It is made up of 320(64x5) SPUs, 16 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Performance-wise, the GeForce GTX 1650 should theoretically be much superior to the Radeon HD 3850 1GB in general. (explain)

GeForce GTX 1650		131072 MB/sec
Radeon HD 3850 1GB		52992 MB/sec
	Difference: 78080 (147%)

Texel Rate

The GeForce GTX 1650 is quite a bit (about 678%) more effective at anisotropic filtering than the Radeon HD 3850 1GB. (explain)

GeForce GTX 1650		83160 Mtexels/sec
Radeon HD 3850 1GB		10688 Mtexels/sec
	Difference: 72472 (678%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 1650 is superior to the Radeon HD 3850 1GB, and very much so. (explain)

GeForce GTX 1650		47520 Mpixels/sec
Radeon HD 3850 1GB		10688 Mpixels/sec
	Difference: 36832 (345%)

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 maximum amount of data (measured in megabytes per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at 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 graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number 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 output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
