GeForce GTX 1650 vs Radeon HD 3870 X2 512MB

Intro

Compare that to the Radeon HD 3870 X2 512MB, which uses a 55 nm design. AMD has set the core speed at 825 MHz. The GDDR3 memory is set to run at a speed of 900 MHz on this model. It features 320(64x5) SPUs as well as 16 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1650 should perform a small bit faster than the Radeon HD 3870 X2 512MB overall. (explain)

GeForce GTX 1650		131072 MB/sec
Radeon HD 3870 X2 512MB		115200 MB/sec
	Difference: 15872 (14%)

Texel Rate

The GeForce GTX 1650 should be quite a bit (approximately 215%) more effective at AF than the Radeon HD 3870 X2 512MB. (explain)

GeForce GTX 1650		83160 Mtexels/sec
Radeon HD 3870 X2 512MB		26400 Mtexels/sec
	Difference: 56760 (215%)

Pixel Rate

The GeForce GTX 1650 will be quite a bit (more or less 80%) more effective at FSAA than the Radeon HD 3870 X2 512MB, and also should be able to handle higher screen resolutions more effectively. (explain)

GeForce GTX 1650		47520 Mpixels/sec
Radeon HD 3870 X2 512MB		26400 Mpixels/sec
	Difference: 21120 (80%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
