Re: But What About Purley?
I assume you mean the Skylake server release?
Not a massive jump in IPC from Broadwell to Skylake and Skylake to Kaby Lake even less so.
The E5 2699v5 is rumored to only have 28 cores (although a 32core rumor has also been spotted).
But the clock speed rumor is only 1.8GHz, So I think this will be neck and neck, Skylake with a little higher IPC but fewer cores, is may just come down to Multi-threading efficiency and frequency)
