Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 3050		130 Watts
Radeon HD 7870 XT		185 Watts
	Difference: 55 Watts (42%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 3050 will be 19% quicker than the Radeon HD 7870 XT in general, because of its greater bandwidth. (explain)

GeForce RTX 3050		229376 MB/sec
Radeon HD 7870 XT		192000 MB/sec
	Difference: 37376 (19%)

Texel Rate

The GeForce RTX 3050 is quite a bit (approximately 40%) faster with regards to texture filtering than the Radeon HD 7870 XT. (explain)

GeForce RTX 3050		124160 Mtexels/sec
Radeon HD 7870 XT		88800 Mtexels/sec
	Difference: 35360 (40%)

Pixel Rate

The GeForce RTX 3050 should be quite a bit (more or less 68%) more effective at full screen anti-aliasing than the Radeon HD 7870 XT, and also will be able to handle higher screen resolutions more effectively. (explain)

GeForce RTX 3050		49664 Mpixels/sec
Radeon HD 7870 XT		29600 Mpixels/sec
	Difference: 20064 (68%)

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 transferred past the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 processed per second. This number 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
