Performance drops, but by a few percent
After the start of sales of the Ryzen 7 7800X3D processor, some motherboard manufacturers (for example, Gigabyte, MSI and ASRock) were quick to assure that their budget models based on the AMD A620 chipset are fully compatible with the new CPU. The enthusiast undertook to check how true this is by choosing the Gigabyte A620 Gaming X motherboard as an example.
It turned out that on a cheap motherboard, the Ryzen 7 7800X3D does not reach the maximum frequency: in tests, it was limited to 4.4-4.6 GHz, while on a motherboard based on the X670 chipset, the CPU overclocked to 4.8-4.9 GHz. Naturally, consumption also varies: the Ryzen 7 7800X3D installed in a cheap motherboard in the Cinebench test consumed 81 watts, while the consumption in the X670 motherboard reached 95 watts.
Does the Ryzen 7 7800X3D need to use only the top X670 motherboard?
But what about the results in the tests? And here is the main surprise: in synthetic tests, the difference in performance was only 5%, and in games – no more than 3%. Hence the conclusion: Ryzen 7 7800X3D can be used with an inexpensive motherboard based on the A620 chipset – performance in games will hardly suffer from this.
Another point – perhaps it makes sense to pay attention to solutions based on the AMD B650 chipset. There are no longer power restrictions, and PCIe 5 support for SSDs will not be superfluous. And the surcharge for this is only 25-50 dollars.
