Intel Core i9-13900KS vs Intel Core i9-13900T

Pros

• First desktop processor to reach 6.00 GHz at stock settings
• 24 cores and 32 threads with hybrid architecture
• Large 36 MB L3 cache and 32 MB total L2 cache
• Supports DDR5-5600 and DDR4-3200 for flexibility
• 20 PCIe lanes with PCIe 5.0 for GPUs and 4.0 for storage
• Unlocked multiplier tailored for overclockers
• Excellent single-threaded and multi-threaded performance

Cons

• Higher price than the Core i9-13900K for small performance gains
• High power draw under turbo, requiring robust cooling and power delivery
• Limited to the LGA1700 platform
• Premium-binned 'Special Edition' with limited availability

Pros

• Excellent performance per watt; very strong efficiency for a 24‑core desktop CPU.
• Full i9 core count (8P+16E) with 32 threads for heavily threaded workloads.
• 35 W base power enables small coolers and quiet SFF builds.
• 5.3 GHz single‑core turbo keeps lightly threaded tasks responsive.
• DDR5‑5600 support and dual‑channel memory for high bandwidth.
• Integrated UHD Graphics 770 with Quick Sync Video for transcoding and display output without a dGPU.
• Supports ECC memory with W680 chipset, useful for servers and workstations.
• PCIe 5.0 and 20 CPU lanes plus DMI 4.0 for modern GPUs and NVMe storage.

Cons

• Low base P‑core and E‑core frequencies (1.1 GHz / 0.8 GHz) reduce performance in power‑limited scenarios.
• Locked multiplier prevents traditional overclocking.
• Maximum Turbo Power of 106 W is still significant under heavy load, requiring adequate cooling and PSU.
• More expensive and harder to find than mainstream i5/i7 T‑series parts with fewer cores.
• Limited upgrade path beyond LGA1700; future Intel desktop platforms will use new sockets.
