Performance Compared

Productivity

Intel Core i7-14700KBest92

The 12 E-cores provide massive throughput for rendering and compilation.

Intel Core i9-7900X89

Strong multi-threaded performance for creator workloads; competitive with or better than many mainstream 8–10 core CPUs at the time, though newer designs are faster per clock.

Gaming

Intel Core i7-14700KBest95

Delivers top-tier framerates, competing directly with flagship CPUs.

Intel Core i9-7900X78

Capable of high-refresh-rate gaming at 1440p and above, but modern gaming-focused CPUs often deliver better minimums and efficiency.

Virtualization

Intel Core i7-14700K90

Excellent for running multiple VMs and containers.

Intel Core i9-7900XBest92

Excellent for running multiple VMs thanks to 10 cores, 20 threads, and quad-channel memory, especially when paired with VT-x and VT-d support.

Efficiency

Intel Core i7-14700KBest70

Power draw can spike significantly under full multi-core load.

Intel Core i9-7900X55

High power consumption and heat output compared to modern 10nm/7nm parts; requires robust cooling and a strong PSU.

Specialized Performance

AI / ML

Intel Core i7-14700KGood
  • CPU-based AI inference is strong due to 28 threads.
  • No dedicated NPU like mobile platforms.
  • Integrated graphics can assist in basic VPU workloads.
Intel Core i9-7900XLimited
  • No dedicated AI acceleration hardware like NPU or AI instructions beyond AVX-512.
  • Suitable for CPU-based inference and small model workloads, but not competitive with modern AI-focused CPUs or GPUs.

Gaming

Intel Core i7-14700KExcellent
  • High single-core boost ensures max FPS in CPU-bound titles.
  • Large cache size benefits modern AAA games.
  • Requires a high-end GPU to avoid bottlenecks at 1080p.
Intel Core i9-7900XGood
  • Strong single-core clocks up to 4.3–4.5 GHz enable high FPS in CPU-heavy titles.
  • Most games don’t scale beyond 6–8 cores, so newer 8-core CPUs often match or beat it in gaming while using less power.
  • Best suited for GPU-bound scenarios at 1440p/4K where the CPU is less of a bottleneck.

Our Verdict on Each

An exceptional desktop CPU that blurs the line between i7 and i9, offering tremendous multi-core value and top-tier gaming clocks.

Best for: Users wanting a single system for high-refresh gaming and heavy productivity.

Read the full review

A once-flagship HEDT CPU that still delivers strong multi-threaded performance and I/O capability, but its 14nm process, high power draw, and discontinued platform make it mainly interesting for used builds or legacy systems.

Best for: Used workstation or creator build on X299 where multi-threaded performance and I/O matter more than efficiency or platform longevity.
