Recently, we took some time to assemble and test new components, especially the new Ryzen 3700X combined with a Gigabyte X570 I Aorus Pro WiFi. And nothing went well, at all.
Motherboard:
The first issue occurred when we tried to boot the board. We had to factory reset the card to finally succeed in this simple process. After installating the OS, we rebooted the computer and, once again, the board didn't turned on. We finally achieved to install Windows by flashing the bios. Then, we proceeded in standard installations of softwares and drivers, started some thermal tests and tried to update the bios - as required by the manufacturer. Bad idea. At the end, the motherboard didn't work at all without any possibility to flash the bios.
CPU:
Following all these unexpected events, we didn't get that time to properly test the 3700X CPU. What we saw, at this point, is that the iddle power & temperature were very high (20/25W - 45/50°C). Plus, the temperatures could be very hot compared to the power consumption - results are worst than any Intel references or even Ryzen 2000 generation. We also noted that the frequency goes down close to 4.0Ghz when temperatures rise. If you are a little bit curious, you will see same results on the web provided by many users, including watercooling users.
Conclusion:
We personally sent back components to our partner. We do not recommend this Gigabyte reference at the moment. Especially considering all other references from older generations didn't show any issue, so far (we use to install B450 I Aorus Pro WiFi from Gigabyte and X470 Gaming from ASRock). Plus, the older generations do not have a fan installed on the chipset. With The First, it is required to remove this part for many references and, if you find a model that doesn't require to remove the fan, it is really annoying at any speed.
For the 3700X reference, we think it is not the best choice for a fanless configuration since the temperatures can get very high. A 9700KF will be a better choice if you want to keep the same range and will even perform better for most of applications due to higher stable frequencies.
