More Specs for Intel’s i9-9900KS have been revealed

When Intel revealed their Special Edition i9-9900KS processor, several questions were raised. First, if 5GHz is the all-core boost, what will the base clock speed be, and second, if the all-core boost is 5GHz, what’s the single-core boost like? 

We now have answers to both of these questions, with Intel confirming to Computex attendees that their i9-9900KS processor will run with a base clock speed of 4.0GHz and a single-core boost clock speed of 5GHz. Yes, Intel hasn’t improved their single-core boost clock speeds with this new iteration of the i9-9900K. 

So what does Intel’s 4GHz base clock mean? Nothing really. With Intel’s basic BIOS the processor will go down to these clock speeds, but in the real-world, no 3rd party motherboard manufacturer uses Intel’s basic BIOS, instead implementing a custom solution which sets the processor’s all-core boost as its minimum clock speed. This means that the i9-9900KS should run at 5GHz at all times on high-end motherboards. 

When compared to Intel’s standard i9-9900K, Intel has boosted the i9-9900KS’ base clock speed by 0.4GHz and its all-core boost clock speeds by 300MHz. The CPU’s single-core boost clock speeds remain the same. Intel demoed their i9-9900KS with a closed loop liquid cooler.
