As per Igor’s Lab, AMD’s 4th Gen Vermeer flagship, the Ryzen 9 4950X will feature a boost clock higher than 4.8GHz. Considering that this is a sixteen core part it’s mighty impressive. Even Intel’s 10th Gen Comet Lake flagship, the Core i9-10900K which features just ten cores boosts slightly more than 5GHz. If AMD can manage a 5GHz boost for its top-end Vermeer part, it’ll come very close to beating Intel in gaming workloads as well.
This info was deducted from the OPN of the chip which is as follows:
While the first part was already known, the last part was discovered this time around. The base clock is 3.5GHz while the boost is limited to 4.8GHz. It’s likely that the final clocks will be very close to these figures as we’re approaching the launch date. A boost of 5GHz would be ideal, but you’ll definitely need liquid cooling to achieve it similar to the 3900XT and the 3950X.
The primary reason why AMD is able to achieve such high clocks on the same node can be explained using a new feature that will be introduced with Vermeer, known as per core voltage adjustment. As the name suggests, it allows the user to set voltages for the individual cores from the BIOS as well as using software. Therefore, you can be sure it’ll be integrated into AMD Ryzen Master later on.
Another interesting but you can in the above AGESA change-log is the addition of per port TXCLK gating for Cezanne. This means that AMD already has the first chips on hand. As for what it does, TXCLK gating makes the processor more power efficient by minimizing activity in parts of the circuit that aren’t involved in calculating the results of the instructions for the present clock cycle.
Furthermore, it also limits clocking during cycles where no results are being generated or if the generated results are redundant and don’t contribute to the final results. The impact of TXCLK gating is especially prominent when the cores are running at partial loads.\]
