GeForce RTX 3050 vs Radeon HD 7950

Intro

The GeForce RTX 3050 comes with a GPU clock speed of 1552 MHz, and the 8192 MB of GDDR6 memory runs at 1750 MHz through a 128-bit bus. It also features 2560 Stream Processors, 80 Texture Address Units, and 32 ROPs.

Compare those specifications to the Radeon HD 7950, which comes with GPU core speed of 800 MHz, and 1536 MB of GDDR5 memory running at 1250 MHz through a 384-bit bus. It also features 1792 SPUs, 112 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

As far as performance goes, the Radeon HD 7950 should in theory be a small bit better than the GeForce RTX 3050 overall. (explain)

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

Texel Rate

The GeForce RTX 3050 should be a lot (more or less 39%) faster with regards to AF than the Radeon HD 7950. (explain)

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

Pixel Rate

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

GeForce RTX 3050 49664 Mpixels/sec
Radeon HD 7950 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.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If it uses 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 processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
