Not even 0.5% to show over the "previous generation" halo part. It's actually 0.3%; this seems to confirm what I was talking about in the preview thread: while clocks are more aggressive, the binning is not and the reduced power limit hurts its performance plenty compared to the 13900KS, which despite the 100 MHz lower targets sustains better averages as the gap between them is completely nil. When properly tweaked out and overclocked, the KS's hand-picked binning may come to shine and prevail over this processor pretty much entirely. No DLVR, no improved IMC, no physical changes. At least it's cheaper, I guess. What a disappointment.
AMD, this is the time to strike. Don't fumble this, it's a rare chance.
Satisfy shareholders and avoid having to tell them that they don't have a product to ship this year.
