One other overclocked benchmark for the Intel Core i9-12900K CPU has appeared which reveals an excellent greater clock velocity of 5.3 GHz throughout all cores but once more with insane quantities of CPU energy necessities.
Intel’s Core i9-12900K Overclocked To five.3 GHz Throughout All Cores & Consumes Up To 400 Watts of Energy
The Intel Core i9-12900K will probably be one in every of three unlocked chips that the blue staff will introduce in November on the Z690 platform. Will probably be the quickest within the lineup and pitted straight in opposition to the AMD Ryzen 9 5950X. We now have seen a number of benchmarks of the chip leak out beforehand however Bilibili content material maker, Enthusiast Citizen, has leaked out one more overclocked results of the chip, this time operating at 5.3 GHz throughout all cores.
Intel Core i9-12900K CPU Specs
Intel’s Core i9-12900K Alder Lake-S CPU will rock 16 cores and 24 threads. That is organized in 8 P-Core (with 16 threads) and eight E-Core (with 8 threads). The CPU options 30 MB of L3 cache which is organized in 3 MB per core partitions on the P-Core (Golden Cove) and three MB per cluster on the E-Core (Gracemont). That is 8 P-Cores for twenty-four MB from the P-Cores and 6 MB from the 2 clusters comprising 4 E-Cores every. There’s additionally 1.25 MB of L2 cache for a complete of 12.5 MB on your complete chip.
As for clock speeds, the Intel Core i9-12900K is predicted to function a P-Core base and enhance clocks of three.2 GHz / 5.3 GHz and E-Core base and enhance clocks of three.0 / 3.9 GHz. These enhance clocks are for a single-core. The all-core enhance frequencies are anticipated to be 5.0 GHz for the P-Core and three.7 GHz for the E-Core.
Intel Core i9-12900K 5.2 GHz Overclocked Efficiency
The CPU was overclocked to five.3 GHz throughout all 8 efficiency cores. Trying on the benchmarks reported inside the CPU-z benchmark, the single-core rating noticed a 2% enhance whereas the multi-threaded rating noticed a 1% enhance over the 5.2 GHz overclock that leaked out earlier. In comparison with Intel’s inventory Core i9-12900K configuration, the rating is a 5% enhance in single and 6% enhance in multi-threaded efficiency.
Versus the AMD Ryzen 9 5950X, the overclocked Intel Core i9-12900K at 5.3 GHz scored a 34% lead in single-core and a 4% lead within the multi-core take a look at. The Ryzen 9 5950X affords 33% greater threads than the Alder Lake chip however the primary factor to notice is the ability consumption.
The Intel Core i9-12900K CPU consumed an insane 400W of energy within the AIDA64 AVX stress take a look at at full load whereas operating at 5.3 GHz (1.44V) and near 300W in the usual SSE CPU-z take a look at. It is usually reported that the AIDA64 stress take a look at solely lasted for a minute earlier than the system shuts itself off for the reason that temperatures had been uncontrolled even when the radiator was submerged in ice to supply extra cooling to the CPU.
The small cores weren’t touched so pushing them too would possibly lead to even greater energy consumption although not as important because the P-Cores. That is greater than twice the ability consumption over the rated PL1 TDP of 125W for the chip and would require an insane quantity of cooling to tame this chip should you plan on overclocking it.
Warmth dissipation restrict! AVX Hurricane 400W! 12900K Pcore full core 5.3G, Ecore Auto 3.7G, Vcore voltage 1.44V.
Even when the pure SSE CPU-Z take a look at energy consumption is near 300W, the AIDA64 AVX can solely final for one minute, even when the chilly drain is soaked in ice water, it’ll nonetheless be overheated and shut down straight.
The identical leaker has additionally reported that he has been in a position to get the chip operating at 4.9 GHz all-core overclock at round 220W. This reveals that there is a slight room for enchancment within the voltages and energy division.
Intel’s Alder Lake Desktop CPUs will function each DDR5 and DDR4 reminiscence controllers and 600-series motherboards can even include DDR5/DDR4 particular choices. Excessive-end motherboards will retain DDR5 whereas the extra mainstream choices will open up DDR4 help too. The Intel Alder Lake CPU lineup is anticipated to launch in November together with the respective Z690 platform and DDR5 reminiscence kits.
