| Power consumption of Rocket Lake compared to Zen 3 & Comet Lake Posted: 10 Jul 2021 10:53 PM PDT Intel's current processors are usually not rated well in the public discussion because of their high power consumption. This is often proven by (high) power consumption values, which however often come from systems that run without power limits. The following list of power consumption measurements of the pure CPU (not the entire system) concentrates on measurements under activation of the official power limits. Thus, there is neither a time expansion at PL2 nor an active "Adaptive Boost". The measurements themselves were mostly realized via simply reading out the package power in corresponding tools (which, according to general experience, is quite accurate).
The limits of this method are quite apparent: Depending on whether the hardware tester specifies a peak consumption (highest peak value) or an average consumption or a consumption after the end of the PL2 phase, very different values can come out for the Intel processors (the differences between average and peak consumption remain much more within limits for AMD). A particularly obvious example of this is the Prime95 measurement from ComputerBase: Sure enough, a Core i9-11900K reaches a peak consumption of 243 watts here, which is simply too much for this CPU. However, it goes down to a constant 125 watts after the PL2 phase is finished (after 56 seconds). Thus, this Intel processor consumes what equivalent AMD processors consume - like the Ryzen 7 5800X, which often exhausts its PPT of 142 watts and thus tends to consume even slightly more than the Intel processor. It's much less clear whether peak or average values were given for the other measurements - the measured values themselves rather point to peak values. However, these are always significantly higher in Intel's processors due to the PL2 influence, which does not represent a statement about the long-term power consumption. Both values are certainly worth knowing, because the PL2 will be seen quite often in daily office work with often very fluctuating loads, even though it is usually only for a very short time. Maybe the hardware testers should think about generally stating both values in the future - peak consumption and averaged consumption. For the averaged consumption, a tool like the Performance Efficiency Suite is also useful, which can be used to record the complete energy consumption of a defined task (unfortunately only Cinebench at the moment). This levels out all short-term higher power consumption values - the way to the target is left to the CPU manufacturers, only the total energy consumption is evaluated. Apart from that, the unpleasantness which Intel currently experiences for the power consumption of Rocket Lake (and Comet Lake before that) is certainly also due to the fact that Intel overdoes it quite a bit with this de facto boost function. Releasing processors with a TDP of 125 watts, which are allowed to consume double that for up to just under a minute, is far away from a "short-term" boost in favor of "snappiness". This is definitely a feature (just) to win benchmarks, according to the development that many benchmarks in the CPU segment have quite short runtimes due to the performance achieved nowadays. Since processor power is mostly available in abundance these days, the mass of users apparently don't want processor models that go for low performance gains above certain power consumption levels that are simply considered "unhealthy". The 200 watt range should simply be reserved for HEDT users who can justify this high power consumption with corresponding processor performance and a real need for it.

| How likely are DP2.0 monitors to come 2021? What can we expect anyway? Posted: 10 Jul 2021 07:35 AM PDT Hey guys, Like the title says : What can we expect from Displayport 2.0 ? Will we finally see 5K2K ultrawides with 120Hz+ ? They were supposed to launch last year, now they are planned for End 2021.
