Our test system draws around 58 W from the mains when idling, which ramped up to an average of 202 W during a one-hour stress test. We also took a closer look at how much power our test system consumed in various scenarios. In short, the increased risk of damaging the CPU is not worth it. Moreover, initial tests online have shown no great improvements from de-lidding the Core i9-9900K. It is possible to de-lid the Core i9-9900K like other processors, but Intel’s decision to solder the heat spreader to the lid makes this a riskier experience than de-lidding the Core i7-8700K. We would recommend pairing the CPU with at least one 240-mm radiator to cool the chip efficiently. We chose a 360-mm radiator for our tests primarily because the Core i9-9900K runs hot. HWiNFO measured a maximum core temperature of 83 ☌ (~181 ☏) during the same stress test, in which the processor achieved a stable 4.7 GHz across all cores. The Core i9-9900K gets hot when operating under sustained load too. HWiNFO measured the Core i9-9900K consuming an average of 131 W during a one-hour stress test, during which power consumption peaked at 161 W. However, our test CPU consumed significantly more than Intel’s claims during our tests. Intel states that its three 9th generation Core processors all have a 95-W maximum TDP. These differences will be most noticeable in multi-threaded applications, which will perform better with the higher core and thread count. In practice, this means that the Core i9-9900K can run up to double the threads in parallel that the octa-core Core i7-9700K can, and ten more than the Core i5-9600K. The Core i9-9900K is the only CPU of the three that supports Intel Hyper Threading, for example.
The quality of CPUs varies so much that some online shops like Caseking offer pre-selected processors that have good overclocking potential.Īll three processors are built on the same die, but Intel has limited its lesser 9th generation chips to create production differentiation. Your successes at overclocking any of Intel’s new CPUs will differ from what we have achieved though as each CPU is different.
I9 9900K CINEBENCH MANUAL
Intel has released the Core i9-9900K alongside the Core i7-9700K and the Core i5-9600K, all of which have unlocked multipliers and support manual overclocking with the corresponding motherboard. The Core i9-9900K can also achieve up to a 95-W thermal design power (TDP) according to Intel, although this remains a theoretical value. The company have manufacturered the Core i9-9900K on its new 14 nm ++ FinFET process and has soldered a heat spreader to the chip to dissipate the heat more efficiently and quickly than previous processors could. The release of the octa-core Core i9-9900K seeks to address this performance gap and Intel has done more than just increasing the chip’s core count. Intel initially countered the Ryzen 7 2700X with the hexa-core Core i7-8700K, but its fewer cores meant that it performed worse in multi-threaded applications. AMD’s resurgence has disrupted Intel’s dominance in the recent years, particularly with the release of the octa-core Ryzen 7 2700X earlier this year.
Intel has focussed on gamers for the introduction of its 9th generation Core Desktop processors.
