Back in March, Intel unveiled its 11th era of desktop processors codenamed Rocket Lake. In its lineup, the flagship desktop chip is the Core i9-11900Ok, with eight cores, sixteen threads, and a present promoting value of $545 at Amazon. Along with apparent efficiency benefits that include the flagship mannequin, together with larger turbo frequencies, Intel has put numerous its newest applied sciences into Rocket Lake together with Thermal Velocity Boost (TVB) and Adaptive Boost (ABT) – the concept right here is to to provide the absolute best efficiency out of the field. In this text, we take 4 retail Intel Core i9-11900Ok processors and 4 premium Z590 motherboards, together with the ASRock Z590 Taichi, the ASUS ROG Maximus XIII Hero, the GIGABYTE Z590 Aorus Master, and MSI MEG Z590 Ace, and overclocking them. Is overclocking value it on Intel’s Core i9-11900Ok? Let’s discover out.
The Core i9-11900Ok: Intel’s Flagship Desktop Processor
Before launching in March, there was numerous dialogue about Rocket Lake’s potential efficiency. On the one hand, it regarded identical to one other 14nm design refresh akin to Skylake. While that is considerably true, the fact is that it gives an development incrementally by way of Intel’s analysis and design mannequin; Rocket Lake is definitely retrofitted its 10nm design onto 14nm, for a number of causes, together with CPU core frequency (it is larger on 14nm), price (14nm is cheaper to fabricate), and peak thermal window. The final level has been one other speaking level as Rocket Lake runs heat. One of the explanations for this, outdoors of refinements and enhancements to turbo frequencies and inside computerized overclocking applied sciences, is Intel’s transfer to PCIe 4.0 which comes instantly from the CPU. As we came upon in our preliminary Core i7-11700Ok evaluation (and verified on the Core i9 and Core i5 fashions), in the event you blast this chip with a robust AVX-512 workload, you’ll be able to draw close to 300 watts, nevertheless day-to-day operating at half that’s simply par for the course.
While there are numerous choices on Intel’s 11th era for desktop, together with varied Core i5, Core i7, and Core i9 processors, the present flagship within the line-up is the Core i9-11900Ok. The Intel Core i9-11900Ok options eight cores and 16 threads. In phrases of specs and working frequencies, the Core i9-11900Ok has a base frequency of three.5 GHz, whereas it has a ‘turbo’ which tops out at 5.Three GHz. At current, Intel’s interpretation of Turbo is fairly complicated and requires digesting in numerous methods than beforehand thought.
Intel Thermal Velocity Boost (TVB) Versus Adaptive Boost Technology (ABT)
As it stands, Intel’s Core i9-11900Ok has 5 ranges of computerized overclocking. This consists of the bottom frequency at default settings, Turbo Boost 2.0 (TB2), Turbo Boost Max 3.0 (TBM3), Thermal Velocity Boost (TVB), and Adaptive Boost Technology (ABT). Below is an outline of what every means:
| Intel Core i9-11900Ok Frequency Levels | |
| Base Frequency | The base frequency is the clock velocity that the processor is assured to run at beneath guarantee circumstances with an influence consumption no larger than the TDP score of the processor (125W). |
| Turbo Boost 2.0 (TB2) | When working in turbo mode, that is the frequency the entire cores will run at. TB2 has totally different ranges of variation relying on what number of cores are getting used. |
| Turbo Boost Max 3.0 (TBM3) | When in turbo mode, one of the best cores (sometimes one to 2) get boosted with additional frequency when they’re the one cores getting used. |
| Thermal Velocity Boost (TVB) | If the height thermal temperature is beneath a given worth (70°C for i9-11900Ok) in turbo mode, all of the cores will increase by +100 MHz. This additionally follows the TB2 frequency relying on what number of/what cores are loaded. |
| Adaptive Boost Technology… | |
