According to a BIOS update released by ASUS for its upcoming motherboards, Intel’s i9-9900KS (which is capable of hitting 5 GHz on all cores) features a 127-watt TDP. That’s a 33.68% increase from the standard “K” chip, which has a 95-watt TDP.
The revelation has enthusiasts wondering just how long the heavily binned chip can manage 5 GHz on all cores. Guru3D points out that the given TDP is in no way indicative of the maximum power used.
A 127W TDP rating is the highest we’ve seen for an Intel mainstream desktop processor for sure. It’s even higher than the forthcoming 10-core Comet Lake-S chip that’s rumored to feature a 125W TDP. In that case, we don’t expect every Intel 300-series motherboard on the market to support the i9-9900KS.
