An unlocked 10-core Cascade Lake-X desktop processor with Hyper-Threading, four-channel DDR4 memory and 48 CPU PCIe lanes for LGA2066 enthusiast systems.
TechSpot and Puget found weak value against Ryzen alternatives in their tested workloads. TechSpot criticised the small generational gains and rendering value; Puget found the 10900X had weaker live playback than the higher-core Cascade Lake-X models. Its platform connections may matter for specialised systems, but neither review makes it a strong general-purpose purchase.
Cascade Lake-X; Hyper-Threading and an unlocked multiplier, confirmed by Intel’s exact-model family product brief.
Clocks
Turbo Boost Max 3.0 up to 4.70 GHz on the preferred cores; ordinary Turbo Boost 2.0 up to 4.50 GHz. Intel targeted November 2019 availability, but first actual sale was not established in the bounded source pass; conservative year precision is retained.
Cache
19.25 MB Intel Smart Cache; Intel’s exact-model product-brief table identifies it as L3 cache.
Graphics and AI
Built-in graphics
No
Graphics
No processor graphics, explicitly confirmed by Intel’s exact-model support table.
