Review and testing of the AMD Ryzen 7 3800XT processor. Red revenge.

Over the past three years, since the release of the first Ryzen, the changes in the desktop processor market have been much more productive than since the introduction of Sandy Bridge back in 2011. AMD has imposed a nuclear race on a competitor, and by this indicator wins victory after victory. If at first the older Ryzen 7 1800X was able to offer users eight cores with SMT support, now the top-end Ryzen 9 3950X

We recently reviewed the Ryzen 9 3900XT, which promised to bring an extra 100 MHz for cores under load. But as practice has shown, we got them in single-threaded calculations, while with full load on the processor, the frequency of all cores was at the level of Ryzen 9 3900X. But with manual adjustment of the parameters, we managed to squeeze the maximum out of the new product, which the previous model was not capable of.

Now we turn our attention to the eight-core Ryzen 7 3800XT.

The model in question occupies a middle position in the updated series, where, in addition to the Ryzen 9 3900XT, there is also a junior solution Ryzen 5 3600XT, thereby AMD has filled all the niches of processors for demanding users. core m

But for the thrifty enthusiasts, the company introduced the Ryzen 3 3100 / 3300X a little earlier, which, when overclocked, compete well with conventional six-core models. But back to our ward.

So, the main characteristics of the Ryzen 7 3800XT remain unchanged.

The TDP level remained unchanged at 105 W, and if the processor does not go beyond the maximum power consumption of 142 W, then the frequency of individual cores can rise to 4700 MHz, which is 200 MHz more than the Ryzen 7 3800X. Under multi-threaded load, the beginner runs at 4200

The processor design has not changed

But this barrel of honey has its own fly in the ointment.

Now it is not surprising that AMD decided not to complete the new product with a boxed cooler and left users to choose a suitable cooling system themselves.

It got better with overclocking, and after the release of the ClockTuner for Ryzen (CTR) program by 1usmus

It overclocks in CCX, which I used to find the maximum frequency on all processor cores, after which I introduced adjustments to the UEFI of the motherboard. The Ryzen 7 3800XT was able to run stably in benchmarks at 4600 MHz with a voltage of 1.333 volts. In this mode, the CPU warmed up to 77 degrees in Cinebench R20 (80

But CCX does not always succeed in overclocking synchronously. If a very unsuccessful core gets into such a complex, then the rest will work at its frequency. As a result, half of the processor can operate stably at 4600 MHz, and the second
