Intel Core i9-13900KS: Power for Enthusiasts and Professionals

March 2025

Key Features: Raptor Lake Architecture and Beyond

The Intel Core i9-13900KS processor, released in late 2022, remains a relevant choice for demanding users even in 2025. Its Raptor Lake architecture is an evolution of Intel's hybrid approach, combining Performance-cores (P-cores) and Efficient-cores (E-cores).

- 24 cores (8 P-cores + 16 E-cores) and 32 threads — P-cores operate at frequencies of up to 6.0 GHz under Turbo Boost Max 3.0, delivering record single-threaded performance. E-cores (up to 4.3 GHz) handle background tasks.

- The Intel 7 process technology (10 nm Enhanced SuperFin) is optimized for a balance between energy efficiency and power.

- 36 MB of L3 cache accelerates data processing in games and professional applications.

- TDP of 150 W (actual consumption can reach up to 300 W under peak loads!).

- Intel UHD Graphics 770 — integrated graphics for basic tasks, but a discrete graphics card is required for gaming or rendering.

Geekbench 6 confirms its leadership:

- 3100 points (Single-Core) — the best result among desktop CPUs at the time of release.

- 21795 points (Multi-Core) — competing with top HEDT processors.

Key Features:

- Support for PCIe 5.0 (up to 16 lanes) and DDR5-5600.

- Thermal Velocity Boost and Adaptive Boost technologies for automatic overclocking.

- Compatibility with Windows 11 and optimization for hybrid cores.

Compatible Motherboards: Socket and Chipset Choices

The processor uses the LGA 1700 socket, compatible with the Z790, H770, B760, and H710 chipsets.

- Z790 — the top choice for enthusiasts:

- Overclocking for P-cores and E-cores.

- PCIe 5.0 support for graphics cards and NVMe.

- Examples of motherboards: ASUS ROG Maximus Z790 Hero ($599), MSI MPG Z790 Carbon WiFi ($479).

- B760 — optimal for most users:

- Basic overclocking support (only for P-cores).

- Prices starting from $200 (e.g., Gigabyte B760 AORUS Elite AX).

Important:

- Motherboards with DDR4 are cheaper but limit memory speed.

- For PCIe 5.0, choose models with enhanced VRM and cooling (relevant when building with RTX 5090 or similar GPUs).

Memory Support: DDR4 vs. DDR5

The i9-13900KS works with DDR5-5600 and DDR4-3200.

- DDR5 (recommended):

- Bandwidth up to 90 GB/s (compared to 50 GB/s for DDR4).

- Better performance in gaming (up to a 15% increase at 4K) and rendering.

- Cons: high price (32 GB DDR5-6000 — $150).

- DDR4 (budget option):

- Suitable for upgrading old systems.

- Example: 32 GB DDR4-3600 — $80.

Tip: For gaming, a combination of DDR5 + last-gen NVIDIA/AMD GPU will provide maximum FPS.

Power Supply: How to Avoid Overload

With a TDP of 150 W and peak consumption up to 300 W (under stress tests), the power supply requirements are strict:

- Minimum 850 W for a system with RTX 4080/4090.

- Recommended 1000–1200 W with an 80 Plus Gold/Platinum certification (for example, Corsair RM1000x — $199).

- Use PCIe 5.0 12VHPWR cables for modern graphics cards.

Real Experience: Users with 750 W power supplies report reboots under simultaneous CPU and GPU loads.

Pros and Cons: Is It Worth Buying?

Pros:

- Best single-threaded performance (gaming, Photoshop).

- Support for DDR4/DDR5 — flexibility in building.

- 32 threads for rendering (Blender, Cinema 4D).

Cons:

- High heat output (liquid cooling is needed, e.g., NZXT Kraken X73 — $249).

- Price: $700–800 (new) in 2025.

- AMD Ryzen 9 7950X3D is more effective in multi-threaded tasks.

Use Cases: Gaming, Work, Creativity

- Gaming:

- Cyberpunk 2077 (4K, Ultra) — 120+ FPS with RTX 4090.

- CS2 (1080p) — 600+ FPS thanks to high frequencies.

- Work Tasks:

- Rendering in Blender (BMW scene) — 2.5 minutes versus 3.1 for Ryzen 9 7950X.

- Video encoding in Premiere Pro — speed increase of 18% thanks to Quick Sync.

- Multimedia:

- Streaming in OBS without FPS loss (E-cores handling the load).

Comparison with Competitors: AMD vs. Intel

- AMD Ryzen 9 7950X3D ($750):

- Better in gaming with 3D V-Cache (up to 10% improvement at 1080p).

- More energy-efficient (TDP 170 W).

- Weaker in single-threaded tasks (Geekbench 6 Single-Core — 2900).

- Intel Core i9-14900K ($650):

- Slight performance gain (5–7%).

- Same LGA 1700 socket, but higher price for upgrade.

Practical Building Tips

1. Cooling:

- A 360 mm liquid cooling system or a top-tier air cooler (Noctua NH-D15) is mandatory.

- Adjust fan curves in BIOS for a balance between noise and temperature.

2. Case:

- At least 3 intake fans (example: Lian Li Lancool III — $169).

3. Storage:

- PCIe 5.0 SSD (Samsung 990 Pro — $200 for 2 TB) for maximum speed.

4. Overclocking:

- P-cores can stably run at 5.8–6.0 GHz with a voltage of 1.35 V.

Final Conclusion: Who is the i9-13900KS For?

This processor is a choice for:

- Gamers looking for maximum FPS at 1080p/1440p.

- Professionals working with 3D, video, and streaming.

- Enthusiasts ready to invest in cooling and power supply.

Alternatives:

- For energy savings — Ryzen 9 7950X3D.

- For a budget build — Intel Core i7-14700K.

In 2025, the i9-13900KS remains relevant due to its unique balance of price and power. It is worth considering if you are not ready to pay a premium for the latest models but want top-tier performance.
