i9-9900K/KS model
Hello, I'm helping you decide on a CPU upgrade. You're currently using an i5-8600K with an ASUS ROG Strix Z370-E board. You're thinking about switching to an i9-9900K/KS. Will the i9 fit on your Z370 motherboard? Would you need a different chipset like Z390? You also run an ASUS ROG Strix RTX 2070 with 32 GB DDR4 at 3200MHz. I'm concerned about potential bottlenecks—anyone with experience can share their thoughts? Thanks, Sveiny.
Hello! I'm concerned the CPU might be too strong for the GPU to handle. Should we consider the new KS release? Would it be worthwhile to get the KS version? Also, are there any performance differences between the Z370 and Z390 models?
I think you won't be hitting 5GHz with an overclocked board. Maybe consider a Z390 or a more advanced setup if you're aiming for a 9900k(s).
You shouldn't stress over your CPU speed. The 9900K is capable of handling more than a 2070, making them a solid match for great gaming. Bottlenecks happen when your CPU struggles with your GPU, causing stuttering or other problems. The KS works well with most motherboards, but unless you find an exceptional price, the difference won't be noticeable, especially during games with the 2070 or multiple 2080TIs in SLI. A typical 9900K usually reaches around 4.7GHz across all cores, which is more than necessary, and your board should handle it without extra effort unless you have a very powerful VRM setup. Also, don't expect a big difference between Z370 and Z390 models.
@Mateyyy no performance difference per se, but z390 has ac wifi and usb gen 3.1. for a 9900k I would go with that z390 board I suggested due to having far superior Vrm cooling compared to his I current board. Higher OC can probably be applied to. End of day depends on silicon too
I currently use a NZXT Kraken X62 cooler with my i5-8600K, and I’m confident it will perform well with the i9-9900k. For this motherboard, I found the ASRock Z390 Taichi Ultimate available in Norway—slightly pricier than the Z390-E board I shared earlier, around $20 more. I’m planning to wait for Black Friday to see better deals, and I’ll decide on a motherboard then.
