By setting Adaptive Voltage to 1.4V we lift the voltage for ratios of 52X and up. This is particularly necessary to ensure stability at the highest ratio we have set: 54X for up to 2 cores. It will also be applied when 3 cores are running at 52X. However, for the other configurations, from 4 cores at 51x to 10 cores at 50x, the default vf curve will be followed. The long story short is that Turbo Boost 2.0 allows the processor to increase the power consumption temporarily above the TDP rating to achieve higher performance. It manages this by accumulating “energy budget” during periods of idle time that can be deployed when necessary during periods of high load.

All models support up to DDR5-4800, LPDDR5-5200, DDR4-3200, or LPDDR4X-4266 memory, and 28 lanes of PCI Express 4.0/3.0. The performance uplift is most notable in multi-threaded benchmark applications which would typically be heavily constraint by the default power limits. All models support up to DDR5-5600 or DDR4-3200 memory, and 16 lanes of PCI Express 5.0 + 4 lanes of PCIe 4.0.Intel® Iris® Xe Graphics only: to use the Intel® Iris® Xe brand, the system must be populated with 128-bit (dual channel) memory. Otherwise, use the Intel® UHD brand. All models support: SSE4.1, SSE4.2, AVX, AVX2, FMA3, Speed Shift Technology (SST), Intel 64, XD bit (an NX bit implementation), Intel VT-x, Intel VT-d, Hyper-threading, Turbo Boost 3.0, AES-NI, Smart Cache, Thread Director, DL Boost, and GNA 3.0. I was the most impressed by the final test result: Prime 95 Small FFT with AVX at 5 GHz. Running a sustained 355W load with high yet stable temperatures and without any errors is just amazing. The upgraded VRM of the Z590 Carbon EK X compared to the Z490 Carbon EK X certainly did not disappoint. Do note that the Memory Try It! function will also adjust voltages if necessary. For example, it will adjust the system memory voltage as well as the CPU System Agent voltage. Make sure to verify the settings and ensure you are comfortable with the raised voltages.

All models support up to DDR5-5200, LPDDR5-6400, DDR4-3200, or LPDDR4X-4266 memory, up to 16 lanes of PCI Express 5.0, and up to 4 lanes of PCI Express 4.0. All models support: SSE4.1, SSE4.2, AVX, AVX2, FMA3, Speed Shift Technology (SST), Intel 64, XD bit (an NX bit implementation), Intel VT-x, Intel VT-d, Intel TXT, Hyper-threading, Turbo Boost 3.0, AES-NI, Smart Cache, Thread Director, DL Boost, and GNA 3.0.Just like the Core i9-10900K, the Core i9-10850K will run right at the limit of your cooling solution if it doesn't have enough available thermal headroom. We used the 280mm Corsair H115i water cooler with the fans cranked to full blast for testing, and just like with the 10900K, the 10850K pushed up to 100C during any type of AVX stress test. That results in thermal throttling that reduces performance over long-run benchmarks. As such, more capable coolers, like 360mm AIOs and custom loops, could expose yet more performance - and power consumption. In more lightly threaded workloads, the 10850K actually seems to use less power, which might indicate that this could be a current density issue being the prime factor in binning.

See http://www.intel.com/content/www/us/en/architecture-and-technology/hyper-threading/hyper-threading-technology.html?wapkw=hyper+threading for more information including details on which processors support Intel® HT Technology.

All turbo modes and power modes above that are not covered by warranty. Intel kind of screwed this up with the Tiger Lake launch in September 2020, by refusing to define a TDP rating for its new processors, instead going for a range. Obfuscation like this is a frustrating endeavor for press and end-users alike. Modern high performance processors implement a feature called Turbo. This allows, usually for a limited time, a processor to go beyond its rated frequency. Exactly how far the processor goes depends on a few factors, such as the Turbo Power Limit (PL2), whether the peak frequency is hard coded, the thermals, and the power delivery. Turbo can sometimes be very aggressive, allowing power values 2.5x above the rated TDP. So in the end we had to settle for DDR4-4266 CL17. This is the same frequency as our XMP but with slightly better memory timings. The 10850K model name doesn't have an F suffix. Non-F CPUs contain integrated graphics, and a separate graphics card isn't required if your motherboard includes video-output connectors (e.g., HDMI).

However, that won’t stop us trying to squeeze out more performance. There are two things we can still tune. All models support up to DDR5-4800 or DDR4-3200 memory, and 16 lanes of PCI Express 5.0 + 4 lanes of PCIe 4.0. There isn't much to chew over here. Compared to the Core i9-10900K, the i9-10850K comes with an across-the-board 100 MHz reduction in the base and boost frequencies. The ten-core 20-thread chip runs at a 3.6 GHz base frequency, peaks at 5.2 GHz, and retains all of Intel's normal boost mechanisms (like Turbo Boost 2.0, 3.0, and Thermal Velocity Boost).

Intel® Thermal Velocity Boost

It's rational to assume the availability issues stem from the 10900K's position at the top of the Comet Lake-S binning chart – it's a premium-binned chip and there simply might not be enough chips coming out of that fabs that land on the higher end of the binning distribution, making it hard to satisfy demand. The resulting price gouging only serves to widen the pricing gap between Intel's halo model and AMD's competing chips that already hold several key advantages. Stress tests often don't correlate to real-world heat output, though, and we recorded a peak of 91C during an extended multi-threaded y-cruncher workload (AVX heavy). The factory set vf curve of this Core i9-10850K is defined from 8x ratio up to 52x ratio as 52x is the highest default turbo ratio available on this CPU. For any ratios higher than 52x the CPU will set the same voltage as for 52x.
