GeForce RTX 3050 vs Radeon HD 7950 3GB

Intro

Compare all of that to the Radeon HD 7950 3GB, which uses a 28 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 RAM is set to run at a frequency of 1250 MHz on this card. It features 1792 SPUs along with 112 Texture Address Units and 32 ROPs.

GeForce RTX 3050		229376 MB/sec
	Difference: 10624 (5%)

Texel Rate

The GeForce RTX 3050 is quite a bit (approximately 39%) better at AF 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 running with a high screen resolution is important to you, then the GeForce RTX 3050 is the winner, by far. (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 (in units of megabytes per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 processed per second. This figure 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 graphics 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 that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
