GeForce GTX 1650 vs Radeon HD 7870 XT

Intro

Compare all of that to the Radeon HD 7870 XT, which comes with a clock frequency of 925 MHz and a GDDR5 memory speed of 1500 MHz. It also uses a 256-bit bus, and uses a 28 nm design. It features 1536 SPUs, 96 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1650		75 Watts
Radeon HD 7870 XT		185 Watts
	Difference: 110 Watts (147%)

Memory Bandwidth

The Radeon HD 7870 XT should in theory perform quite a bit faster than the GeForce GTX 1650 in general. (explain)

Radeon HD 7870 XT		192000 MB/sec
GeForce GTX 1650		131072 MB/sec
	Difference: 60928 (46%)

Texel Rate

The Radeon HD 7870 XT is a small bit (more or less 7%) better at anisotropic filtering than the GeForce GTX 1650. (explain)

Radeon HD 7870 XT		88800 Mtexels/sec
GeForce GTX 1650		83160 Mtexels/sec
	Difference: 5640 (7%)

Pixel Rate

The GeForce GTX 1650 should be quite a bit (about 61%) more effective at full screen anti-aliasing than the Radeon HD 7870 XT, and also should be able to handle higher screen resolutions while still performing well. (explain)

GeForce GTX 1650		47520 Mpixels/sec
Radeon HD 7870 XT		29600 Mpixels/sec
	Difference: 17920 (61%)

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 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. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
