GeForce RTX 3050 vs Radeon HD 7970

Intro

Compare those specs to the Radeon HD 7970, which features GPU clock speed of 925 MHz, and 3072 MB of GDDR5 RAM set to run at 1375 MHz through a 384-bit bus. It also features 2048 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

Memory Bandwidth

Theoretically speaking, the Radeon HD 7970 should perform a bit faster than the GeForce RTX 3050 in general. (explain)

Radeon HD 7970		264000 MB/sec
GeForce RTX 3050		229376 MB/sec
	Difference: 34624 (15%)

Texel Rate

The GeForce RTX 3050 will be a little bit (more or less 5%) better at AF than the Radeon HD 7970. (explain)

GeForce RTX 3050		124160 Mtexels/sec
Radeon HD 7970		118400 Mtexels/sec
	Difference: 5760 (5%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce RTX 3050 is superior to the Radeon HD 7970, and very much so. (explain)

GeForce RTX 3050		49664 Mpixels/sec
Radeon HD 7970		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 max amount of data (measured in MB per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total number of texture units of the card by the core clock 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 processed in one second.

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