These CPU were submitted last month, and it was already clear that it is unlikely they have a special meaning. For the beginning of the performance, and mention at the same time “normal” model, so you can see the difference.
As you can see, it is almost there. The increase of 100-200 MHz peak frequency, which is achieved not always, obviously will not lead to any significant increase in performance. In fact, even the AMD results in this chart.
Now for the real tests. Today, the Network appeared a huge number, but I will mention only a few — the situation is clear and so.
Yes, the increase on average is only 2-3%, and in some applications it is at the level of accuracy. Power consumption and temperature regime has changed about the same.
Why are these CPU? If you focus on the recommended prices, they are the new models identical to the old. That is, Ryzen 9 3900XT is the same as Ryzen 9 3900X. But it’s recommended prices. Let me remind you, Ryzen 9 3900X together with other models of the line came last summer and has managed to considerably cheaper. Not all models fell equally, but, for example, Ryzen 9 3900X in the United States today is not $ 500, and $ 430. That is the moment to buy the upgraded CPU makes no sense.
But AMD they were produced not in order to really make their lineup better. Just had to respond to the recently released the Intel line of Comet Lake-S, so we are only in marketing. In addition, not all buyers understand PC hardware, but there is supposedly a new CPU, which was released even later than competing solutions from Intel. Oh and don’t forget about the market of ready PC, which is quite large.
In General, if you are going to buy an AMD processor while in the direction of the XT models don’t have to look — take something of the main line or wait for the new generation, which will be presented, presumably, in October.
