GeForce RTX 3050 vs Radeon HD 7990

Intro

The GeForce RTX 3050 features core speeds of 1552 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 RAM. It features 2560 SPUs as well as 80 TAUs and 32 Rasterization Operator Units.

Compare all of that to the Radeon HD 7990, which features a core clock frequency of 950 MHz and a GDDR5 memory speed of 1500 MHz. It also makes use of a 384-bit bus, and makes use of a 28 nm design. It features 2048 SPUs, 128 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 3050 130 Watts
Radeon HD 7990 375 Watts
Difference: 245 Watts (188%)

Memory Bandwidth

In theory, the Radeon HD 7990 should be 151% quicker than the GeForce RTX 3050 overall, due to its higher bandwidth. (explain)

Radeon HD 7990 576000 MB/sec
GeForce RTX 3050 229376 MB/sec
Difference: 346624 (151%)

Texel Rate

The Radeon HD 7990 is much (about 96%) faster with regards to anisotropic filtering than the GeForce RTX 3050. (explain)

Radeon HD 7990 243200 Mtexels/sec
GeForce RTX 3050 124160 Mtexels/sec
Difference: 119040 (96%)

Pixel Rate

The Radeon HD 7990 will be quite a bit (approximately 22%) better at FSAA than the GeForce RTX 3050, and capable of handling higher screen resolutions better. (explain)

Radeon HD 7990 60800 Mpixels/sec
GeForce RTX 3050 49664 Mpixels/sec
Difference: 11136 (22%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Bandwidth is the max amount of data (measured in MB per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its 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 - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
