VS

GeForce RTX 3060 vs Radeon R9 390X 8G

Intro

The GeForce RTX 3060 has core speeds of 1320 MHz on the GPU, and 1875 MHz on the (Unknown) MB of GDDR6 RAM. It features 3584 SPUs as well as 112 Texture Address Units and 48 Rasterization Operator Units.

Compare that to the Radeon R9 390X 8G, which has GPU clock speed of 1050 MHz, and 8192 MB of GDDR5 RAM set to run at 1500 MHz through a 512-bit bus. It also features 2816 SPUs, 176 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 3060 170 Watts
Radeon R9 390X 8G 275 Watts
Difference: 105 Watts (62%)

Memory Bandwidth

Theoretically speaking, the Radeon R9 390X 8G should be 4% quicker than the GeForce RTX 3060 in general, due to its higher bandwidth. (explain)

Radeon R9 390X 8G 384000 MB/sec
GeForce RTX 3060 368640 MB/sec
Difference: 15360 (4%)

Texel Rate

The Radeon R9 390X 8G is quite a bit (approximately 25%) more effective at AF than the GeForce RTX 3060. (explain)

Radeon R9 390X 8G 184800 Mtexels/sec
GeForce RTX 3060 147840 Mtexels/sec
Difference: 36960 (25%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 390X 8G is a better choice, but not by far. (explain)

Radeon R9 390X 8G 67200 Mpixels/sec
GeForce RTX 3060 63360 Mpixels/sec
Difference: 3840 (6%)

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 maximum amount of data (in units of megabytes per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
