This isn't anything new, but I got to play with a U6780A at work. I don't how long I get to use it before my coworkers want it back. If anyone is interested in particular benchmarks let me know.

CenTaur's lab in Texas was publicly liquidated betwen the 12th and 17th of February. The future of CHA and the CNS core architecture will likely appear only with Zhaoxin, and the remaining CHA processors and boards may appear in various places if whoever purchased the lots at auction has any intention of distributing them.

But if you'd like to see what they can do, one person at least got one and has been running it through the gauntlet.

The new Chinese CPU matches AMD with half the Cores and less consumption
source:
https://cuba.detailzero.com/technol...with-half-the-Cores-and-less-consumption.html

This is first open benchmark 16-cores ZHAOXIN Kaisheng KH-40000 Series x86 processor at 2.7GHz. The Kaisheng KH-40000 Series x86 processors (code name YONGFENG) can go up to 32 cores and 64 cores (on a dual-socket platform)!

"Houston, we have a problem"

P.S. Don't forget, YONGFENG is very "similar" Centaur CNS microarchitecture.

Zhaoxin KH-4000 16c/16t, 32MB L3, 2.7GHz (?) all-core clock, 16nm node
Epyc 7601 32c/64t, 64MB L3, 2.7GHz all-core clock, 14nm node

Here's the complete set of results. The suite measures integer performance:

Benchmark descriptions
Very impressive showing for the Zhaoxin with only a quarter of threads, if the leak is reliable.

New KH40000 results:

2 Processors, 32 Cores
ZHAOXIN KaiSheng KH-40000/16
source:
https://browser.geekbench.com/v5/cpu/15706425

CentaurHauls Family 6 Model 71 Stepping 2 vs CentaurHauls Family 7 Model 11 Stepping 3
CNS vs KH-40000
L1 Instruction Cache is 64KB per core and this is differend from Centaur CNS
L3 Cache is 8MB per eight core cluster and this is differend from Centaur CNS with 16MB L3 cache per eight core

Interesting to see where the changes affect performance. Granted my baseline result is at 2420MHz, but the KH40000 looks to be lagging behind significantly in single-core performance despite sharing the fundamentals of the core pipeline. They must be incurring some penalty from the split cache.

Refreshed processor: higher frequencies and especially a new integrated graphics card

ZHAOXIN KaiXian KX-6000G (4C 3.2GHz, 4MB L2) with ZX C1080 GPU (SM6.0, 512MB, PCI) (D3D 11)

Interesting performance for an integrated graphics core as a successor to IP S3 Graphics/VIA.
