Strengths & Weaknesses
Pros
- 10 cores and 20 threads provide strong multi-threaded performance.
- Up to 5.2 GHz single-core boost benefits gaming and responsiveness.
- Integrated UHD Graphics 630 for basic display and Quick Sync.
- Mature LGA1200 platform with broad motherboard and cooling ecosystem.
- Often cheaper than K‑series parts while offering similar core counts.
Cons
- 65 W nominal TDP is misleading; PL2 can reach ~224 W under turbo.
- Locked multiplier limits overclocking headroom.
- 14 nm process is less efficient than newer 10 nm / 7 nm alternatives.
- Older architecture with no AVX-512 or DL Boost like 11th/12th gen.
- Discontinued, so long-term availability is limited to used and NOS stock.
Pros
- Very low 35W TDP for quiet and compact builds
- Includes capable UHD Graphics 750 with Quick Sync
- PCIe 4.0 support for faster storage and GPUs
- Configurable TDP-down to 25W for ultra-efficient operation
- Good performance for everyday tasks and media playback
Cons
- Low base clock (1.5 GHz) for a desktop CPU
- High power limits under load (PL2 115W) negate efficiency under stress
- Discontinued platform with no upgrade path
- Outperformed by modern low-power CPUs in efficiency and performance
- Locked multiplier limits tuning options

Our Verdict on Each
A powerful 10-core Comet Lake CPU that delivers strong gaming and threaded performance at stock, but its 65 W TDP is misleading; under multi-threaded loads it can draw ~224 W when power limits are relaxed, and efficiency lags modern alternatives.
Best for: Used or discounted builds where you already have an LGA1200 motherboard and want a cheap 10-core CPU for gaming and mixed work.
Read the full reviewA capable but niche processor for users who prioritize low power and heat over maximum performance, though it's outperformed by modern CPUs in efficiency and speed.
Best for: Used or refurbished build for a compact, quiet, low-power desktop with integrated graphics.
