Intel Core i9-13900K, 13th Gen Raptor Lake Flagship CPU, Specs, Price, Performance and Availability – Everything We Know So Far

Intel Core i9-13900K is the flagship chip of the 13th Gen Raptor Lake Desktop CPU family that supports the LGA 1700/1800 socket platform. Like its predecessor Alder Lake, the Raptor Lake chip adopts a similar hybrid architecture design, composed of P-cores and E-cores but with more cores, higher clocks and larger cache for faster performance.

Intel Core i9-13900K CPU: 13th Gen Raptor Lake desktop flagship with 24 cores and 5.5 GHz clock speed

[Updated- 02/07/22]

While we’ve already covered what Intel’s 13th Gen Raptor Lake and Z790 platform brings to the table here, I believe the fastest chip in the lineup deserves its own roundup. Intel’s Raptor Lake isn’t a massive architectural upgrade but a refinement of the existing Alder Lake design that appeals to gamers and content creators alike. The Core i9-13900K is the flagship of this lineup and should prove to be the real deal by not only displaying a decent CPU performance gain over the Core i9-12900K but also against AMD’s Ryzen 7000 flagship chip based on the Zen 4 core.

Intel 13th Gen Raptor Lake Desktop CPUs Expected Features:

  • Up to 24 cores and 32 threads
  • Brand New Raptor Cove CPU Cores (Higher P-Core IPC)
  • Based on 10nm ESF ‘Intel 7’ process node
  • Supported on existing LGA 1700 motherboards
  • Dual-channel DDR5-5600 memory support
  • 20 PCIe Gen 5 lanes
  • Enhanced overclocking features
  • 125W PL1 TDP (Flagship SKUs)

Intel has yet to officially confirm the Core i9-13900K CPU part but there are multiple leaks confirming its existence and the chip will get an even faster ‘special edition’ variant with higher clock speeds. So with that being said, let’s get on with the specs.

Intel Core i9-13900K ‘Raptor Lake’ CPU Specifications

In terms of specifications, the Intel Core i9-13900K CPU offers a total of 24 cores and 32 threads. These are divided into 8+16 configurations, which include 8 P-cores based on Raptor Cove and 16 E-cores based on Gracemont core architecture. All these cores are built on the 10nm ESF or ‘Intel 7’ process node. Using the same process node, the chip has more cores and cache, making the overall die size slightly larger than Alder Lake’s C0 desktop die.

Regarding the cache, the Intel Core i9-13900 Raptor Lake CPU also has 16 MB L2 cache for P-cores (2 MB per core) and 16 MB L2 cache for E-cores (4MB per cluster of 4 cores). This gives us a total of 32 MB of L2 cache, which combined with the L3 cache gives us a total of 68 MB of cache, which is rumored to be labeled ‘game cache’.

Exact clock speeds are currently unknown but we’ve seen models ranging from 4.0 (ES1) to 5.5 GHz (ES3). Current rumors are that single-core clocks are expected to peak at 5.8 GHz for the final retail segment while the all-core boost is expected to peak at 5.4-5.5 GHz. The CPU has a base TDP of 125W (PL1) and a PL2 TDP (or MTP – Maximum Turbo Power) of around 250W. The actual figure is said to be a maximum of 253W, which is 12W higher than the Core i9-12900KS.

Similar to Alder Lake, Intel Raptor Lake CPUs including the Core i9-13900K have no AVX-512 support as it has been removed from current and future mainstream processors. The CPU also offers advanced DDR5 memory support while retaining DDR4 support. DDR5 memory is natively supported with speeds up to 5600 MT/s and one can expect speeds of up to 8000 MT/s when Raptor Lake hits the market.

On the other hand, the CPU gets some enhanced overclocking features like the following:

  • Added per-core OC TVB support
  • Package OC TVB support is added
  • Added efficient TVB support

Recently, OneRaichu has been ahead of the curve in hunting down Intel CPU rumors that the 13th Gen Raptor Lake CPUs may include a SKU that includes a Turbo clock speed of up to 6 GHz, the Intel Core i9-13900KS. This makes Raptor Lake the first x86 CPU family to offer a clock frequency that breaks the 6 GHz barrier. In the clock department AMD is known to be achieving 5.5 GHz+ on multiple threads with their own Zen 4-powered Ryzen 7000 chips and rumors of 5.6-5.8 GHz single-core clocks in the air, while Intel looks like it’s unleashing all it’s capable of with Raptor Lake.

Intel Core i9-13900K ‘Raptor Lake’ CPU Performance

Coming to the performance department, Intel has officially said that the Raptor Lake CPUs will deliver a double-digit performance boost. They haven’t said whether it’s single-core or multi-core but based on recent leaks, we can say that the performance bump will mostly come in the multi-threaded segment due to the increased core count while the single-core performance will also get a decent bump thanks to the increased clocks and cache.

Intel’s Core i9-13900K Raptor Lake ES1 CPU is mostly on par with the Intel Core i9-12900K with a clock speed of 4.0 GHz while the ES3 CPU ends up 7% faster in single and 28% faster in multi-threaded tests. It offers 34% higher single-thread and 21% higher multi-thread performance against the AMD Ryzen 9 5950X. Now that AMD is expected to get an additional >15% single-thread IPC uplift and an overall >35% multi-thread uplift, which comes through a combination of architectural and clock improvements, gen-over-gen with gen 4 Ryzen 7000 CPUs will be a really close battle between the two flagships.

As far as gaming performance is concerned, the Intel Core i9-13900K CPU is said to be the best chip when it comes to running games. We’re told the CPU will reclaim the gaming crown from AMD’s Ryzen 7 5800 X3D for a while before AMD returns with its 3D V-Cash lineup, which is also expected to debut this year.

Intel Core i9-13900K ‘Raptor Lake’ Price and Availability

The pricing strategy to launch Intel’s 12th Gen Alder Lake lineup was very aggressive and it certainly helped AMD’s Ryzen sell enough units to make a dent in its market share and revenue. Segments like the Core i5 and Core i7 are showing up as ‘top 10 sellers’ at several NA and EU-based retailers while the top Core i9 parts are where enthusiasts settle.

Intel is likely to keep raising the prices of its chips. Intel raised the price by just $50 US when it doubled the core count from 8 in the Core i9-11900K ($539 US SEP) to 16 in the Core i9-12900K ($589 US SEP). Since the Raptor Lake doesn’t double and is mostly a revision of the Alder Lake, we can expect the price to remain the same and hit the $599 US mark at most. AMD’s flagship is likely to cost around $700-$800 US which means Intel may have a big edge in price for the performance department.

In terms of launch and availability, Intel 13th Gen Raptor Lake desktop CPUs with the 700-series chipset family are expected to launch in the second half of 2022. The launch is rumored for Q4 2022 which means we could soon see these chips go live in September or October, which would be the right time for the next-gen AMD Ryzen 7000 CPUs. Both AMD and Intel will be pushing their flagship CPUs on their respective flagship platforms so we can’t wait to see the final battle in a few months.

Are you planning to upgrade your Alder Lake CPU to Raptor Lake once it hits the market?
