Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 3050		130 Watts
Radeon HD 7950 3GB		200 Watts
	Difference: 70 Watts (54%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 7950 3GB should perform just a bit faster than the GeForce RTX 3050 overall. (explain)

Radeon HD 7950 3GB		240000 MB/sec
GeForce RTX 3050		229376 MB/sec
	Difference: 10624 (5%)

Texel Rate

The GeForce RTX 3050 should be a lot (approximately 39%) more effective at texture filtering than the Radeon HD 7950 3GB. (explain)

GeForce RTX 3050		124160 Mtexels/sec
Radeon HD 7950 3GB		89600 Mtexels/sec
	Difference: 34560 (39%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce RTX 3050 is the winner, and very much so. (explain)

GeForce RTX 3050		49664 Mpixels/sec
Radeon HD 7950 3GB		25600 Mpixels/sec
	Difference: 24064 (94%)

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 largest amount of data (measured in MB per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range 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 figure is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
