However, the biggest problem with the Core i9-10900K might not even be its performance or the price, but rather availability. There’s been plenty of speculation recently that the 10th-gen Core series release is closer to a paper launch than Intel is willing to admit. We have it on good authority that this is indeed the case with pre-orders opening up a few weeks ago, retailers have very little stock and while the demand hasn’t been crazy, it's heavily outstriped supply, leaving retailers with orders they simply can’t fill. In other words, the chances of getting a Core i9-10900K in the short term will be extremely remote and from what we can gather, Intel isn’t promising retailers any kind of supply at this point. If supply is going to be so limited, that will see price scalping and will ultimately result in buyers going with Ryzen instead.
