How could it be otherwise, from China comes the leak of a mini-review of the Intel Core i7-13700K and the Intel Core i5-13600K, although the disappointment is that we only have a performance comparison concerning its predecessors, and another of the great disappointments is in the energy consumption and the high temperature that they can reach?
Let’s start by reminding you that the Intel Core i7-13700K is a 16-core and 24-thread CPU (8x P-Core + 8x E-Core), while the Intel Core i5-12600K offers 14 core and 20-thread (6x P-Core + 8x E-Core). Regarding its counterparts in Alder Lake, the main difference is in having gone from 4 to 8 E-Core cores, while the Turbo frequencies have increased by 400 MHz for the Core i7 (5.40 GHz) and 300 MHz for the Core i5 ( 5.20GHz).
Additionally, the L2 cache memory has been doubled (24 and 20 MB respectively), and they now support faster DDR5 memory, 5600 MHz .
After going into context, In CPU-Z, the Core i7 13900K is 10% faster than the Core i7-12700KF in single-core performance and up to 34% in multi-core. In the case of the Core i5-13600K compared to the i5-12600K, the single-core improvement is 5% and the multi-core is up to 41%.
With this, we see that single-core performance improvements are tied to a frequency increase, with no IPC improvements, and the additional 4 low-power cores help multi-core.
In the case of the Core i7-13700K, we are talking about all the cores moving at a temperature between 101 and 108ºC, which is close to the maximum tolerated by the CPU to shut down the system as a protection method. Although it must be taken into account that this is an extreme analysis and that in real conditions, it should not reach said consumption. However, there are no details of the cooling either, but go thinking of at least a liquid with a 280 or 360 mm radiator.
Although they are engineering samples and the versions will come out somewhat refined, do not expect the energy consumption to be reduced excessively. That will not happen until the Meteor Lake arrives, debuting a more advanced manufacturing process.
