Zhaoxin's ZX-F/KX-7000/KH-40000 and beyond

There is likely some whitelist of processors or families.

Can we see a comparison of it against an Alder Lake -N?

Its get beat by a Ryzen 1700, why would you bother with anything in the last 7 years ?

Because Alder Lake -N can't even beat that Ryzen

Actually N305 outperforms 1700X in single thread. Multi thread is axed by TDP.

Indeed, funny story Alder Lake -N without the TDP issue, could be really strong.

The IPC Bulldozer is absolute nonsense. But for Zhaoxin, in the MAGA world, even negative publicity is just publicity.

CPU-Z
AMD FX-8350 4.0GHz @ 4.2GHz Turbo 8-core processor: 242 / 1 566 (68,75% / 55,36%)
Zhaoxin KX-7000 3.0GHz 3.5GHz Turbo 8-core processor: 352 / 2 829 (+45,45% / +80,65%)

Cinebench R23
• AMD FX-8350 4.0GHz @ 4.2GHz Turbo 8-core processor: 579 / 3803 (85,15% / 76,20%)
• Zhaoxin KX-7000 3.0GHz @ 3.5GHz Turbo 8-core processor: 680 / 4 991 (+17,44% / +31,24%)

etc.

The chip is rather simplistic and got a horrible memory access latency. Its firmware might be bugged or it simply does well only in fit-to-cache benches.

It's Phenom I all over again

Lenovo Kaitian N8 Pro laptop review: The mobile version of Zhaoxin KX-7000 is even more efficient than Intel/AMD​

[igor_kavinski]

How did they conclude it's more efficient than Intel/AMD CPUs?

What's up with that awful memory read performance?

 

[DZero]

And again... the same issue, iGPU is trash. Zhaoxin needs to go with AMD or nVIDIA in the GPU department to fully shine.

 

[igor_kavinski]

Give them a decade more. They'll be great as emulation machines for Windows XP and Windows 7 compatible software. They should put all their efforts behind making ReactOS and Wine work better with their hardware.

China's Zhaoxin KH-50000 CPU has been taped out. This CPU has 96 cores and its IPC is 30% higher than that of KX-7000, reaching the level of Skylake.

Are there any news about new products?

 

[Kosusko]

China’s Zhaxoin KH-50000 Chiplet CPUs To Feature Up To 96 Cores For Servers, 384 MB Cache, 12-Channel DDR5 Memory, 128 PCIe 5.0 Lanes & New ZPI 5.0 Interconnect With Support For Quad-Socket Systems​

P.S. In addition, Zhaoxin introduced the KX-7000N series of consumer processors, which differ from the existing KX-7000 chips by the presence of a neural processing unit (NPU).

According to Zhaoxin's IPO documents KH-50000 is not based on previously announced (on prospectus for investors) "next-generation (...) increase IPC by 1.3 times" core , but on Century Avenue/Shijidadao (kx-7000). So it is basically KH-40000 on lower node and chiplets, without rumored SMT.

If KX-7000 (6nm) shares cores chiplet with KH-50000, then what was 5nm project that VIA taped out? NPU chiplet for KX-7000N?

98, 141, 226. Just search both documents for kh-50000.

Translated:
Meanwhile, the company will apply the Chiplet interconnect architecture in the development of subsequent server processors. This will ensure high computing performance for future server products while significantly increasing the development efficiency of server processors and reducing R&D costs. For instance, the company's next-generation high-performance server processor chip, the KH-50000, adopts the "Century Avenue" core microarchitecture. Also based on advanced process technology, it will feature a significant increase in processor core count, I/O specifications, and performance compared to the KH-40000 processor.

 

[Kosusko]

Century Avenue=Shijidadao (Kaixian KX-7000 Series) is only slighty modified 16nm Youngfeng (Kaisheng KH-40000 Series).

And Kaisheng KH-50000 Series is only slighty modified Century Avenue=Shijidadao (resp. Youngfeng).

Kaisheng KH-50000 IPC equal to Kaixian KX-7000 Series (Century Avenue=Shijidadao) / Kaisheng KH-40000 (Youngfeng).


The upcoming Kaixian KX-8000 Series is a completely new microarchitecture and IPC is 30% higher than Kaixian KX-7000 Series (Century Avenue=Shijidadao)

Just one more product, that they are not focused on. Hard to watch, how Zhaoxin is wasting sand on fruitation every R&D project, what is only delaying something good and polished.

 

[Markfw]

Do you( anybody here) have any reviews with benchmarks against other products like AMD and Intel ? If not, as said above, its a waste of sand.

 

[MadRat]

Only waste if you can do better. With tighter export controls this is baby steps.
