Funny how these slides always seem to leak right after a competitor announcement ;) Anyhow, we're talking about Intel's new Sunny Cove architecture, which is still out for quite a while. Mind you that Sunny Cove is a four-core series proc baked at 10nm. Intel already made claims that it IPC improvements would be 18% and even 40% in some workloads.
That comparison is against Skylake by the way. Also, that info, however, is from Intel themselves, and in my lifetime I've seen manY official intel figures, and let's call them 'not always accurate'.
However now a list of single-core benchmarks (CPU-Z) has appeared on a Chinese forum for some Sunny Cove and Ryzen 3000 chips. Given that a Ryzen 2700X achieves a score of 488, we can state that (as far as these benchmarks are real) Ryzen 3000 does indeed entail serious IPC improvements. Intel is also doing very well because the benchmark shows that an i7 9700K achieves comparable results with one of the Sunny Cove chips at just 3.7 GHz. We are already adding our salt, but if it is true these figures are impressive.
You need to wonder though, how would an Asia website with an unknown forum member get access to unreleased processors from both sides with, apparently, full support of the procs in CPU-Z?
Salt, grain, lots of it.
