Zhaoxin KaiXian x86 CPU Tested

What's the equivalent level of performance in terms of AMD/Intel CPUs? Sandy Bridge or thereabouts? Because for the past few years, PCs have basically been "fast enough" for most things, super-inefficient monstrosities like Electron excluded. In fact my "daily driver" is probably slower than this Chinese CPU.

Incidentally, there is an interesting and active market in Chinese motherboards with X79/X99 chipsets, which are from that era, along with used Xeons and such.

Obviously those who place performance above all else will not be buying these.

Seems to be roughly in line with https://ark.intel.com/content/www/us/en/ark/products/129945/... in some benchmarks as per the article

Some Reddit searching suggests a geekbench score comparable with a FX-8100

It's also worth saying that these comparisons can be overly favourable as (from the architectural design perspective) you can effectively get some performance for free from the roughly 4 process doublings in between this and the Bulldozer.

Only one process doubling. This is 16nm and Bulldozer was 32nm.

Its obviously still quite a bit behind architecturally, though.

Density has gone from about 7.5 on GF to 28 on TSMC if I read correctly.

Ah, so around 1.9 doublings. Seems like I was wrong :)
