That chip is going to be amazing for people who need major multithreading. For everyone else, the (I assume) lower clock speeds are going to be a detriment to performance.

Intel's Core i9-13900K Raptor Lake CPU has been overclocked to a very impressive 8.2 GHz clock frequency using LN2 cooling.
The overclocking feat was achieved by Legendary overclocker, Allen Golibersuch aka SPLAVE during the Intel Creator Challenge just a few hours ago. During the event, Intel invited SPLAVE to showcase some overclocking capabilities of the Raptor Lake chip over the Livestream and we got to see an 8.2 GHz overclock.
The CPU used by SPLAVE was the Intel Core i9-13900K which is the top Core i9-13900K chip for this year. I say this year because there's the Core i9-13900KS planned for next year that will offer clocks of up to 6 GHz. The Core i9-13900K comes with 24 cores, 32 threads, 68 MB of cache, a single-core boost of up to 5.8 GHz, and a multi-core boost of up to 5.5 GHz across all cores. For this particular OC, the chip only had its 8 P-Cores (Raptor Cove) enabled and SMT was disabled. The motherboard used was the next-gen ASRock Z790 Taichi.
Intel's 13th Gen Core i3-13100 Desktop CPU has been spotted and features a very entry-level design carrying just four P-cores.
At launch, Intel's 13th Gen Raptor Lake CPU family will only include the "K" series parts such as the Core i9-13900K(F), Core i7-13700K(F), and the Core i5-13600K(F). However, Intel is also prepping up mainstream Non-K and T-Series parts as we have seen leak out over the past several months. The mainstream lineup is what's going to be the main challenge for AMD to tackle as they currently have no AM5 parts that are available at the same value as those or even the existing 12th Gen CPU line.
One such part within the lineup is the Intel Core i3-13100 CPU which has now appeared within the CPU-z database. The Raptor Lake chip or should we say, Alder Lake, comes with a four-core design which is all P-Cores and 8 threads. The reason why we say that this is an Alder Lake part and not a Raptor Lake chip is that it has the same cache structure as the Alder Lake Core i3-12100 with a 12 MB L3 and a 5 MB L2 design. Intel's 13th Gen lineup is expected to feature a mix of Raptor Cove & Golden Cove chips as detailed here.
The CPU was spotted running at clock speeds of 3.41 GHz and these are definitely not the final clocks. You can see that the multiplier and bus speed have been modified since the Core i3-12100 already comes with a base/boost clock of 3.3/4.3 GHz, there's no way that its successor will offer lower clock speeds. The CPU was tested on a Gigabyte B660 Gaming X motherboard & it's known that 13th Gen CPUs will be compatible with existing 600-series & also the newer 700-series boards.
In the latest benchmarks posted by Enthusiast Citizen over at Bilibili Forums, we get to see the Intel Core i9-13900K Raptor Lake CPU being tested within Cinebench R23 in various profiles. The results range from stock, unlimited power, and limited power profiles. But before that, let's take a quick re-cap of the specs.
The Intel Core i9-13900K is the flagship Raptor Lake CPU, featuring 24 cores and 32 threads in an 8 P-Core (Raptor Cove) and 16 E-Core (Gracemont V2) configuration. The CPU is configured at a base clock of 3.0 GHz, a single-core boost clock of 5.8 GHz (1-2) cores, and an all-core boost clock of 5.5 GHz (all 8 P-Cores). The CPU features 68 MB of combined cache and a 125W PL1 rating that goes up to 250W. The CPU can also consume up to 350W of power when using the "Unlimited Power Mode" which we detailed here.
- Core i9-13900K 8+16 (24/32) - 3.0 / 5.8 GHz - 66 MB Cache, 125W (PL1) / 253W (PL2)
- Core i9-12900K 8+8 (16/24) - 3.2 / 5.2 GHz - 30 MB Cache, 125W (PL1) / 241W (PL2)
Coming to the performance benchmarks, the Intel Core i9-13900K scores 38,431 points at stock and that's on par with the AMD Ryzen 9 7950X. Using the "Unlimited Power" profile, the score jumps to 40,622 points which is a 6% increase. The leaker also posted another benchmark, this time with the CPU running at a fixed 80W power limit, and scored 27,412 points which is on par with Intel's Core i9-12900K Alder Lake CPU.
It looks like the slides were shown during a recent Raptor Lake pre-launch events, which are now taking place around the world for the tech press and analysts. It is not clear if these slides in particular are under embargo, but it is clear that they have not been shared before. That’s simply because AMD Ryzen 7000 series were not available yet when Intel was announcing their Raptor Lake series.
According to this slide, Intel Core i9-13900K is offers -1% worse to 22% better performance than AMD Ryzen 9 7950X in gaming. Both CPUs are the flagship of the new desktop series. On average, Intel CPU will be 11% faster than AMD Zen4 CPU.
Another slide shows productivity benchmark from PugetBench, Procyon or AutoCAD/AutoDesk. Intel claims it will reach parity in half of the benchmarks, with 3% loss in Photoshop test and 4% to 16% gain with AutoDesk/CAD.
