Soon after AMD announced their latest “Zen 4” CPUs in the form of Ryzen 7000 Series, Intel, in October 2022, launched their 13th Gen processors with code name Raptor Lake. At the time of the launch, the Core i9 13900K is the top-of-the-line processor of this generation (subsequently dethroned by Intel Core i9 13900KS). On paper, it looks like a beast of a processor with whooping 24 Cores and 32 threads. But how does it compare with the likes of AMD Ryzen 9 7950X, which is the top-of-the-line CPU in the Ryzen 7000 Series (at least until the launch on their 3D V-Cache variants)? Is the Intel Core i9 13900K the best gaming CPU at the moment? What about the power consumption and thermals? In this article, we will review the Intel Core i9 13900K processor and compare its gaming and multi-threading performance against some popular Intel and AMD CPUs.
A Brief Note on Intel Core i9 13900K
Since Intel came out of the quad core bubble, it always had a catch up game with AMD, who with their “Ryzen” CPUs hit the ball out of the park. While it played around with higher core count CPUs until the Intel 11th Gen Rocket Lake processors, Intel entered a territory that was once the “trademark” stuff of ARM processors (big.LITTLE architecture).
We are talking about the combination of powerful cores and power efficiency cores. Intel calls them Performance or P Cores and Efficiency or E Cores. This lead to a hybrid architecture, starting with their 12th Gen CPUs code named Alder Lake.
Architecture
The Hybrid Architecture from the 12th Gen Alder Lake processors was a success. Making further improvements, Intel launched the Raptor Lake 13th Gen CPUs, with the Intel Core i9 13900K leading the chart.
Similar to the previous gen’s counterpart, the Intel Core i9 12900K, the 13900K also has 8 Performance (P) Cores with support for multithreading. But the efficiency cores doubled. While the 12900K has only 8 Efficiency (E) Cores, the Intel i9 13900K has 16 Efficiency (E) cores.
As efficiency cores doesn’t support multithreading, the Intel Core i9 13900K has a total 32 threads (16 P + 16 E). The microarchitecture of the 13th Gen CPUs are the updated Raptor Cove P Cores and Gracemont E Cores.
Under the hood, the “Raptor Cove” cores have a 15% single-threaded performance gain when compared with the previous gen’s “Golden Cove” cores. The E cores are same for both 12th Gen and 13th Gen CPUs.
The base clock speed of the P and E Cores of 13900K are 3 GHz and 2.2 GHz respectively. This is lower than the 3.2 GHz and 2.4 GHz of the 12900K. But the turbo clock has seen a significant bump.
For the 12900K, the turbo clocks of P and E Cores are 5.1 GHz and 3.9 GHz respectively. But for 13900K, there is roughly a 6% boost in the turbo clock for P core at 5.4 GHz and a 10% boost for E Cores at 4.3 GHz.
Intel made the 13th gen Raptor Lake processors using the same LGA 1700 Socket as the 12th Gen Alder Lake CPUs. So, if you have a decent motherboard, then the upgrade cost will be less.
Memory and Cache
The Intel Core i9 13900K CPU supports both DDR4 and DDR5 RAM types in dual channel mode. While the DDR4 frequency is same as 12th gen’s DDR4-3200, DDR5 saw a huge improvement with support for DDR5-5600 (12th Gen maxed out at DDR5-4800).
Support for DDR4 means, you don’t need to make a significant investment, if you already own a decent DDR4 RAM kit. But the industry is moving towards DDR5 and the cost of DDR5 RAM kits is slowly coming down.
The main change between the 12th Gen Alder Lake processors and the 13th Gen Raptor Lake processors is in the implementation of the Cache.
Each P core of the 13900K Processor gets 2 MB L2 Cache (this was only 1.25 MB for 12th Gen Processors). One module of E cores gets 4 MB L2 Cache (again a huge bump from only 2MB per module for 12th Gen).
If you aren’t familiar with the E Core modules, Intel grouped four E Cores into a cluster that share the L2 cache. So, in 13900K, you get 4 MB for four E Cores. This makes the total L2 Cache of 13900K at 32 MB. It also has 36 MB L3 Cache, which is common for all the cores.
PCIe and Power
The Intel Core i9 13900K processor has 20 PCIe lanes from the CPU. Of these, 16 are PCIe Gen 5 while the remaining 4 are Gen 4. The final configuration of the PCIe lanes will depend on the motherboard you select and the corresponding chipset.
Similar to the Alder Lake processors, even the 13th Gen Raptor Lake processors are fabricated using the “Intel 7”. Even though Intel calls it “Intel 7”, it is technically a 10 nm node.
The base processor power of Intel Core i9 13900K CPU is 125W while the maximum turbo power is 253W.

Final Verdict
With a retail price of $640 and the performance it offers, the Intel Core i9 13900K seems like a decent CPU from Intel. But if you take a look at the power consumption and the thermals, we are no impressed.
If your workload involves multithreaded applications that need a lot of CPU computational power, then the AMD Ryzen 9 7950X seems like a better choice than the Intel Core i9 13900K. Even though former is expensive that needs a new DDR5 Memory and AM5 Motherboard, it runs 5°C cooler and consumes 100 Watts less.
When it comes to gaming, the performance difference between the Intel Core i9 13900K and the Intel Core i7 13700K is very less. The latter runs a little cooler while consuming less power.
Overall, while the we are impressed with the performance both in terms of gaming and productivity workloads of the Intel Core i9 13900K, its power consumption and thermals might be a concern. This might not a deal breaker, especially if your workload involves primarily productive applications.
