GeForce RTX 3050 vs Radeon HD 7770

Intro

Compare those specifications to the Radeon HD 7770, which has a GPU core clock speed of 1000 MHz, and 1024 MB of GDDR5 RAM set to run at 1125 MHz through a 128-bit bus. It also features 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Radeon HD 7770		80 Watts
GeForce RTX 3050		130 Watts
	Difference: 50 Watts (63%)

Memory Bandwidth

Performance-wise, the GeForce RTX 3050 should in theory be a lot superior to the Radeon HD 7770 in general. (explain)

GeForce RTX 3050		229376 MB/sec
Radeon HD 7770		72000 MB/sec
	Difference: 157376 (219%)

Texel Rate

The GeForce RTX 3050 should be a lot (more or less 210%) faster with regards to texture filtering than the Radeon HD 7770. (explain)

GeForce RTX 3050		124160 Mtexels/sec
Radeon HD 7770		40000 Mtexels/sec
	Difference: 84160 (210%)

Pixel Rate

If running with high levels of AA 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 7770		16000 Mpixels/sec
	Difference: 33664 (210%)

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 (measured in MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could 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 Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
