News Chinese-Produced Zhaoxin KX-6000 CPUs Purportedly Match Intel's Core i5-7400

[BFG-9000]

Half as fast per core as two year old Intel is actually surprisingly fast, like Bulldozer fast. I'd have expected them to be nearer a decade behind.

As for the folks thinking the government would have to mandate a backdoor for it to happen, well the Snowden documents revealed that the only antivirus companies the NSA did not expend any resources to hack or reverse engineer were the three big American ones, including Microsoft. I'll bet they only had to ask nicely, and perhaps pay them a little for their trouble.

Actually Goldmont Plus is quite a bit better. The overall score is not such a good comparison.

Comparison of Integer performance shows that Goldmont Plus is 27% better. Zhaoxin gets ahead because of memory performance. The stupid thing about the overall score is that it puts Memory in a separate category altogether. Integer/FP testing are affected by Memory performance so the overall scores are counting memory performance twice.

The memory controller on these Intel Gemini Lake SoCs looks somewhat hobbled (has lower memory bandwidth) compared to those from Intel's mobile SoCs with Intel's Core architecture. Just for example https://browser.geekbench.com/v4/cpu/compare/13096479?baseline=11595714 that Intel Pentium 4415Y is also 6W TDP.

Do you know if both of those systems have the same number of memory channels and RAM speed?

BTW, the N5000 manages surprisingly well against that Kaby Lake - even in single-core scores!

Well, that Intel Pentium 4415Y can only use LPDDR3 or DDR3L memory, while that Intel Pentium N5000 can use LPDDR4 or DDR4. Thus that Intel Pentium N5000 should have more memory bandwith with faster DDR4 type memory (up to 2400 MT/s). And since those benchmark results chosen are the highest (under Windows operating system), both should be running on dual channel memory mode as well.

Its also double the cores. 4 full cores vs 4 threads. It would make sense that even as a lower power part it should fare better in multicore performance with 4 full cores.

Ignore the memory clocks and memory bandwidth figures. It's because N5000 can Turbo to 2.8GHz.

Still considering the TDP it manages the N5000 is an impressive little CPU. Too bad Intel heavily deemphasized it probably because they were afraid to cannibalize their bigger chips.

Heh, at first, I accidentally compared it to an i5-7400 running Geekbench 5, but that's definitely not comparable with v4 scores!

Here's a v4 result for i5-7400 running Linux:

https://browser.geekbench.com/v4/cpu/14483007

Basically, as the article says, the multi-core scores are comparable, though the single-core scores are almost double for the i5. The strongest area of the test chip is definitely crypto, while Intel has more memory bandwidth and better multi-core integer performance.

Thanks for sharing.

The more the Chicoms mess with technology the more they oppress other people, be they Tibetan, Uyghur or people from Hong Kong. That is sad and says that hate is their driving force.

Not to comment on that, but what most bothers me is that we're already seeing them supply other governments with repressive leanings. If the USSR had their current tech for surveillance and online filtering & propaganda, the Berlin Wall would probably still be standing.

I doubt this advancement came without intellectual property theft. AMD, INTEL, IBM need to do their due diligence.

The implied idea here that only US companies are capable of designing and manufacturing processors is simply absurd and ridiculous! Probably RACIST too!

Hahahahaha! What is sad is the inability of some people to recognise that science and technology is NOT the preserve of any race - or political system. As the Chinese Communists - and others - are clearly demonstrating.

This has nothing to do with them not being american,intel amd and ibm are more than 50 years ahead of anybody that is trying to start to make a CPU right now and that is what makes this dubious.

It's not absurd to be a little curious/suspicious of how quickly China is catching up, given how long it took existing CPU makers to reach the current level of sophistication.

In actual fact, there's nothing nefarious going on, here. VIA owns Centaur (a US-based design house), and the lineage of the Zhaoxin chips seems to trace back to them. Here's what WikiChip says about the WuDoaKou cores, the predecessors of the KX 6000 series' LuJiaZui cores.

WuDaoKou is largely a brand new architecture designed by Zhaoxin. This is a departure from earlier microarchitectures such as ZhangJiang which were a lightly modified version of VIA Technologies (Centaur) architecture.

Probably RACIST too!

Nor is it racist, given how many ethnic Chinese and even immigrants from China currently work in US-based semiconductor development. But, also consider that most big semiconductor companies actually do some work inside China.

I agree with this, though some economic systems are more fertile than others. Just look at what happened since China started to embrace capitalism.

Anyway, the comment you replied to was definitely wrong and out-of-line, with the claim of hate being the driving force. I would down-vote it, if I could.
