The result itself is not that impressive, however. One review found that the 3800X achieves about 10100 points in Time Spy, right below the leaked 3800XT score of 10400. However, the leaked CPU was running 2933 MHz RAM, so there is some room for improvement since that review’s 3800X was using 3200 MHz RAM with tight timings. Still, memory will only get you so far, so this score still isn’t really that impressive. But it should be noted that since we do not know the testing conditions, it’s possible that perhaps this isn’t operating with a normal power limit or some other thing is going on that is dragging down performance.
4.8 GHz is a higher boost clock than even seen on the 3950X. Either through binning or switching to the 7nm P node (which is not difficult and increases clocks by 7%), AMD has been able to achieve higher clock speeds on a lower end part. For the 3900XT, could we even see 4.9 or 5 GHz? Maybe, but keep in mind that AMD only hits these clock speeds for like a hundred or so milliseconds, so it’s not exactly a big deal. What matters most is sustained clock speed, and judging by this leak, the sustained clock speed isn’t much higher, if it’s even higher at all, than the original Matisse.
