These are the rumored "Zen+" processors, which seem to have memory-controller updates and clock speed boosts compared to the original Zen release. Mostly because AMD upgraded the process from 14LPP to 12LP, but otherwise the architecture is almost untouched.<p>There seems to be a press embargo for another few days, but the leaked benchmarks from various Youtubers seem to be quite promising (especially considering that the Ryzen architecture hasn't changed. Apparently these memory controller updates were good enough to get IPC-bonus to this 2nd gen release).<p>I'd still wait for official benchmarks from major reporting outlets before buying. But it seems like an overall good "minor" update to the Ryzen line of chips.<p>Rumors are ~5% to ~10% performance boost from 1800x to 2700x. There is a slight boost in IPC due to better memory, as well as higher clocks.<p>Since the 2700x comes with a free CPU Cooler (and the Wrath Prism is a surprisingly good cooler for $0), it will be a better value than the last generation for sure. 1800x launched at $500, but the 2700x launches at $329 with a free CPU cooler.<p>This is definitely a very high-value deal. Great price/performance, although I'm still going to be cautiously optimistic until official benchmarks are revealed in a week or so. Its safer to confirm those rumors before believing them!
