CPU Comparison
Intel Core i7-11700B vs Intel Core i9-11900K
A side-by-side comparison of specs, performance and value. The Intel Core i7-11700B is an 8-core, 16-thread desktop processor built on the Tiger Lake-H architecture, exclusively featured in the NUC 11 Extreme 'Beast Canyon'.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Sustains high all-core clocks due to the 65W desktop TDP.
Good lightly‑threaded performance thanks to high IPC, but falls behind 12‑ and 16‑core Ryzen 9 parts in heavily multi‑threaded workloads.
Gaming
Performs identically to a desktop i7-11700 in gaming, limited only by the mobile GPU form factor.
Strong gaming performance, often matching or slightly beating Ryzen 7 5800X at high clocks, but not dramatically ahead of cheaper alternatives and surpassed by later Intel and AMD generations.
Virtualization
8 cores and 16 threads handle local VMs and containers easily.
Capable for basic VMs, but 8 cores and relatively high power under load limit its appeal compared to more efficient, higher‑core‑count CPUs.
Efficiency
10nm SuperFin is efficient, though 65W is standard for desktops.
High power draw and heat output under multi‑threaded loads, especially with AVX‑512, make it one of the less efficient high‑end desktop CPUs of its era.
Specialized Performance
AI / ML
- AVX-512 support is useful for local AI development
- 8 cores provide decent throughput for medium models
- Supports Intel DL Boost (AVX‑512 VNNI) for some AI inference workloads
- No dedicated AI hardware; modern CPUs with NPUs or better efficiency are preferable for serious AI workloads
Content Creation
Gaming
- 24MB L3 cache provides a noticeable boost in CPU-bound games
- PCIe 4.0 ensures no bottleneck with modern desktop GPUs
- Pairs well with RTX 3060 and 3070 in NUC form factors
- Strong single‑threaded and 1080p high‑refresh performance
- Competitive with Ryzen 7 5800X in many titles at similar clocks
- Newer mid‑range CPUs often match or exceed it in value and efficiency

Our Verdict on Each
A unique desktop part offering excellent 8-core performance and PCIe 4.0 in a specialized NUC form factor, though limited by its proprietary platform.
Best for: Purchasing a used NUC 11 Extreme for a compact, powerful living room gaming PC
Read the full reviewA fast, hot‑running 8‑core CPU that excels in gaming and lightly‑threaded work but is outclassed in efficiency and heavy multi‑thread by cheaper Ryzen 5000 and later Intel parts, making it a niche buy outside of discounted LGA1200 upgrades.
Best for: Upgrading an existing LGA1200 system (Z490/Z590) with strong cooling and a discounted 11900K, where you want better single‑threaded and gaming performance without changing platforms.
