D&H BX80673I99940X
The 14-core, 28-thread Skylake chip boosts to 4.4 GHz (4.5 GHz with Turbo Boost Max 3.0) and supports 4-channel DDR4, making it a strong multi-tasking workhorse. Its unlocked multiplier and 165W TDP allow overclocking, though it lacks integrated graphics, so a dedicated GPU is required. Best for content creators and engineers running heavy multi-threaded workloads like video rendering or 3D modeling on an X299 platform.
