When Ryzen processors hit the market, their success was far
from obvious. Intel is a tough competitor to face, and in 2017 it was the clear
leader in the industry, in terms of product diffusion and performance. Today
the situation has changed radically, Intel continues to grind huge revenues and
still offer interesting performances, but the failure to arrive of the 7nm
production node has left the field free to AMD, which is gaining ground every
month.
After all, the Zen 2 processors have convinced everyone and
their technological load is considerable. A few weeks ago AMD launched a small
refresh of this architecture, of which we reviewed the 3600XT and 3800XT
models, only the top of the range was missing, the Ryzen 3900XT . Again, no
revolution, just a small upgrade in operating frequencies, for a processor that
confirms all the qualities of its predecessor.
The specifications and placement of the Ryzen 3900XT
We have already talked about the new Ryzen 3600XT and
3800XT, in this article we will therefore point directly to the test of the
Ryzen 9 3900XT, as an integration to the previous review. This processor is
equipped with 12 Cores and 24 Threads and is made with a 7 nm manufacturing
process, further optimized compared to traditional variants to achieve two
objectives. The first is the increase in the clock, which remains the same as
regards the base frequency, of 3.8 GHz, but rises to 4.7 GHz in boost mode. The
second is the maintenance of the consumption seen with the Ryzen 9 3900X
released last year. As we will see both of these targets have been reached, the
3900XT maintains the TDP at 105 W and from our tests the consumption is
substantially in line with the previous model.
This can only confirm the goodness of AMD's proposal, which
has managed to get a little more out of an architecture on the market for a
year now.
The launch period of the XT range makes these CPUs
attractive for those who are now assembling a new PC and do not want to wait
for the next-gen. There is also another positive aspect, namely the repositioning
of the "old" models : in the case of the Ryzen 9 3900X the price
drops $ 449, against the $ 499 of the new variant. In short, AMD's move makes
more sense than one might think at first glance and allows it to better occupy
the different market segments.
To measure the performance of the Ryzen 9 3900XT we used the
same configuration used in the review of the other variants, consisting of the
ROG CrossHair VIII Wi-Fi motherboard, RTX 2080 Ti, 16 GB of RAM at 3200 MHz and
ROG PG27UQ monitor.
As in the case of the 3800 XT and 3600XT the performance
jump is small compared to the previous models but it is still present and
slightly more incisive. Nothing revolutionary however, the XT range is not born
to bring a marked increase in performance . The scores of the synthetic
benchmarks show the 3900XT a slight advantage over its predecessor, coming
closer to the i9-9900K in the single core tests, the strength of the Intel
solutions, which instead lag behind in the multi-core ones, by virtue of a
smaller number of computing units.
In the gaming field, the higher clock speed is felt, even in
this case without incisive changes but it is still palpable in the frame rate
of the tested games. The test of this Ryzen 9 3900XT therefore confirmed the
impressions we had with the other models, and that to see important changes in
performance we would have to wait a few more months, with the arrival of the
Ryzen 4000.
