Zhaoxin KiaXian KX-U6780A 2.7GHz in the Anandtech CPU 2021 Benchmarks Database

Flavor text for the link:

"It appears that a 70W, 8C version of this CPU is able to be definitively better than an 8C AMD Jaguar CPU @ 2.35ghz, in many cases beating it by double digit percentages! Except for when it doesn't and it's slower by significant margins."

;)

I guess that is one way to "target" AMD.

Yup. Comparing it to Ryzen is just painful: https://www.anandtech.com/bench/product/2625?vs=2671

The TDP is what holds it back. If they could get the power down there might be some hope for the poor thing. Except that there are ARM chips in the 5-6W range that would still scorch it.

MLPerf Inference v1.0: 2000 Suite Results, New Power Measurements

Compare that to Centaur, which has provided a handful of data points for its upcoming CHA AI coprocessor.

● Centaur Integrated x86 CPUs (2.0GHz) - Centaur Integrated AI Coprocessor (2.0GHz)
● Centaur Integrated x86 CPUs (2.5GHz) - Centaur Integrated AI Coprocessor (2.5GHz)

Wait.. that CentaurHauls looks like a massive jump from Isaiah.
Finally VIA is about to pull a Conroe's Jump?
If that so, finally!

Because Centaur / VIA Isaiah "CN" (CNA, CNB, CNC, CNQ, CNR and also Zhaoxin Zhangjiang, WuDaoKou, LuJiaZui) belonged and belongs to the category of little cores. We know this category of little processor cores in competition under the names Intel Atom (eg Silvermont, Airmont, Goldmont, Goldmont +, Tremont or Gracemont) or AMD "cat cores" (as Bobcat, Jaguar or Puma).

And the Centaur CNS x86 microarchitecture is base as typical representative of big cores. The x86 CHA microprocessor is designed to high-performance x86 CNS cores deliver high instructions/clock (IPC) for server-class applications.

Only many reviewers mixed pears and apples (little and big cores) and then wondered. Let's leave aside motivation or ignorance...
I'm wondering how to turn or feel beautiful on big.LITTLE cores in to Alder Lake SoC...

But anyway. I am preparing review of processors with little cores as Intel Pentium Silver J5040 (Goldmont+); Intel Pentium Silver N6005 (Tremont) and Zhaoxin Kaixian KX-U6580 (LuJiaZui). Stay tuned...

We will see how 14nm Gemini Lake Refresh (Goldmont Plus) and especially 10nm Jasper Lake (Tremont) against 16nm CMOS Kaixian KX-U6580 (LuJiaZui) are prepared in terms of microarchitecture, lithography, performance, TDP, power consumption in the desktop segment (nettop).
It will give us important data ... We look forward to the small cores of Gracemont in big.LITTLE Alder Lake.

Not being snide, however Gemini and Jasper are going to exceed Kaixian as expected.
Even those mondo-L2's aren't help Kaixian much.

We'll see if IPC and higher frequencies quad Goldmont Plus or Tremont cores help skip eight KaiXian (Centaur) cores with higher L2 cache.

Let's be surprised ...

All processors wich you compared only in passmak are based on the architecture of big cores.
My review is called Rise of the small cores.
Let's be surprised. We will see.

A8-9600 has "big cores"? Sure, whatever.
The Excavator processor architecture is big. So, while the cores are small, the blocks FE/LS/FPU/BUS/L2 are all relatively large. Which is the legacy of AMD's big OoO queues for server/HPC for post-K8/Greyhound architectures. K9 (5GHz Operton) had it and K10 (Bulldozer) had it. Which in turn continued to develop in that direction, both SR/XV had bigger OoO queues than BD/PD. Even though they never appeared in the true Server/HPC product lines. So, yes A8-9600 CPU processors are huge, big, large, grand, ginormous, etc.

Hence, why 4.67 Jaguar single-core processors fit in 1 Excavator dual-core processor.
