GeForce RTX 3050 vs Radeon HD 7970

Intro

The GeForce RTX 3050 comes with clock speeds of 1552 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 memory. It features 2560 SPUs as well as 80 TAUs and 32 ROPs.

Compare those specs to the Radeon HD 7970, which uses a 28 nm design. AMD has set the core speed at 925 MHz. The GDDR5 memory works at a speed of 1375 MHz on this model. It features 2048 SPUs along with 128 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 3050 130 Watts
Radeon HD 7970 250 Watts
Difference: 120 Watts (92%)

Memory Bandwidth

The Radeon HD 7970 should in theory be just 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 should be a little bit (approximately 5%) better at texture filtering 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 the winner, 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.

Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 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 anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output 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.
