Binned-CPU seller Silicon Lottery has begun selling a trio of double-binned Intel Core i9-9900KS Special Edition processors for those who desire guaranteed clocks at or above 5.0 GHz. The best of the best, which can hit 5.2 GHz, have already sold out despite costing $1,199.99. Paying over $600 more for a 200 MHz improvement seems ridiculous, but there is a definite market for it.
The core voltage is increased from 1.250V to 1.325V and the multiplier from 50 to 52. The Core i9 9900KS @ 5.2GHz runs at a CPU multiplier of x52, with Vcore of 1.325V and AVX offset of 2. If you were to buy a random Intel Core i9-9900KS from any other retailer, Silicon Lottery mentions that 3 percent of these pre-binned chips would achieve this performance of achieving a stable 5.2GHz (at this low voltage).
