Gaming

Intel Core i9-10900Very Good
  • High single-core clocks (up to 5.2 GHz) benefit high-refresh-rate gaming.
  • 10 cores help with background tasks while streaming or using Discord/overlay.
  • Modern titles with heavy engine workloads can still favor newer architectures.
Intel Core i9-10900EModerate
  • Single-core turbo up to 4.7 GHz helps maintain high FPS in CPU-light titles
  • Lacks the clock headroom and cache of unlocked Comet Lake-S parts
  • Best paired with a midrange GPU for 1080p gaming; not ideal for high-refresh competitive builds

Strengths & Weaknesses

Intel Core i9-10900

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.
Intel Core i9-10900E

Pros

  • 10 cores and 20 threads for strong multi-threaded performance
  • 65 W TDP suitable for constrained thermal environments
  • Intel vPro eligibility for business manageability and security
  • Integrated UHD Graphics 630 for basic display and quick-sync
  • Extended embedded availability and stable platform lifecycle
  • Good balance of clock speed and core count for mixed workloads

Cons

  • Older 14 nm process with higher power consumption than newer architectures
  • Locked multiplier and no overclocking headroom
  • PCIe 3.0 only, with just 16 CPU lanes
  • Max turbo lower than unlocked Comet Lake-S desktop parts
  • Platform is end-of-life for mainstream desktop, with no upgrade path beyond 10th Gen

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 review

A capable 10-core embedded Comet Lake CPU with strong multi-threaded performance and integrated graphics, now best suited for specialized industrial and edge builds rather than new general-purpose desktops.

Best for: Building or specifying an embedded or industrial system that explicitly requires LGA1200, long-lifecycle availability, and vPro manageability.
