Intel Core i9-13900K Raptor Lake CPU Review Shows Big Gains In Multithreading And Decent Gains In Gaming, But All At The Cost Of Higher Power
We’ve already seen a ton of benchmarks for the Intel Core i9-13900K and other Raptor Lake CPUs from various leaks and there’s nothing we don’t know yet.But the review from ESCM was a collaboration with One Raichu, one of the most prominent leakers on Twitter who is very accurate in his reports. So, let’s start with the specs.
Intel Core i9-13900K 24 Core Raptor Lake CPU 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 with 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 eight P cores). The CPU features a total cache of 68 MB and a 125W PL1 rating of up to 250W. And when using “Unlimited Power Mode”, the CPU will consume up to 350W of power. 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)
Intel Core i9-13900K test setup
For this particular review, the Intel Core i9-13900K was tested on both DDR5 and DDR4 platforms. The Z690 Taichi Razer Edition and his unnamed Z790 motherboard were used, but due to NDA we cannot reveal the actual product name.
The motherboard was tested with DDR5-6000 CL30 and DDR4-3600 CL17 memory kits and a Radeon RX 6900 XTXH graphics card. A NZXT Kraken X73 AIO was used to cool the CPU. While the CPU can support native memory speeds up to DDR5-5600, Alder Lake will only support native JEDEC speeds of his DDR5-4800.
Intel Core i9-13900K vs Core i9-12900K performance test:
The test was split into two parts, OneRaichu evaluated memory, bandwidth, and cache performance between the Raptor Lake Core i9-13900K and Alder Lake Core i9-12900K, while Enthusiast Citizen tested standard single-core, multi-core, and and ran the game. application test. First, we prepared a latency benchmark. OneRaichu shows how a new ring bus design with boosted frequencies works. This results in higher latency as all P and E cores achieve uniform latency and do not drop to lower frequencies. I’ve seen it on Alder Lake CPUs.
on the other hand, No significant improvement in IPC for P-Core as detailed here, which improves overall single-threaded performance due to an increase in overall frequency and caching. Compared to Alder Lake, the Raptor Lake Core i9-13900K delivers a 12.5% single-threaded performance boost. The Gracemont E-cores have a small IPC performance improvement of around 6%, and we can see that adding E-cores to the 13900K significantly improves multi-threaded performance. The 13th generation flagship delivers an average 42% performance improvement over its predecessor, which is a huge leap.
We also have a variety of games tested by the outlet, and those that rely on CPU performance seem to see a significant boost, averaging around 10%. It is. This is due to his L2 and L3 cache size increases for the 13th Gen Raptor Lake CPUs. We’ve already seen how a large amount of cache can help in-game on AMD’s Ryzen 7 5800X3D. Therefore, if we conclude the results presented in this review, we can conclude that:
- Intel Core i9-13900K “Raptor Lake” vs 12900K “Alder Lake” MT – +42% improvement
- Intel Core i9-13900K ‘Raptor Lake’ vs 12900K ‘Alder Lake’ ST – +12.5% improvement
- Intel Core i9-13900K “Raptor Lake” vs 12900K “Alder Lake” Gaming – +10% improvement
But all this comes at the expense of higher power. The Intel Core i9-13900K consumes 253W under load in the FPU test on AIDA64, while Raptor Lake reaches up to 343W when you unlock “unlimited power mode”. This is a stress test and your actual power usage in games and applications will vary, but these numbers will be shared later by Enthusiast Citizen. You can read the full review hereIt remains to be seen if this much performance boost is enough for Intel to tackle AMD’s Ryzen 7000 CPUs, which have massively improved single-threaded and multi-threaded performance. We have to wait until the dust settles by.
