I recall that the 35% figure was from a news article that was posted here some time ago. Specifically, it refers to the percentage difference in performance improvement between the N+1(8nm) process and TMSC 7nm process moving from the 14 nm process.

From the figures in that article, I recall vaguely calculating the actual performance difference between the 2 processes to be around 15%.

To very briefly explain, as an example, the 35% figure could have come from TMSC 7nm process (moving from the 14 nm process) achieving about 60% of performance improvement and the N+1(8nm) process achieving about 40% improvement (over the 14nm process).

But that doesn't mean their absolute performance difference is 35%!

I guess haters will always try to interpret the figures in the worst ways possible.

Not going to say how big the difference actually is to be clear, since that would require absolute rather than relative metrics which we clearly don’t have on hand (like what’s the voltage leak, what’s minimal switch time and minimal switch voltage, etc). Just pointing out that they’re not talking about the “performance” of the industrial process.

When semiconductor fabs talk about performance difference of a process it might either be transistor density (per mm2) or power use per transistor. Those are typically the two metrics they use to compare a process.

Media Statement on the Bloomberg Report​


The Bloomberg report is an impressive act of journalistic contortionism. It begins with an unsubstantiated story – one that was supposedly kept secret for almost a decade – and ends with wild speculation. Despite claims of "evidence", it's unclear why their sources didn't go public with this story sooner.
Huawei has been operating in Australia for nearly 20 years, and this is the first time we're hearing of what would normally be considered a fairly headline-worthy event. Two Australian telecom operators, Optus and TPG, have already publicly denied any knowledge of the alleged incident. What's more, the report refers to a type of threat that is highly technical and sophisticated in nature, but it only cites the opinions of politicians and former government officials. Again, it's unclear why Bloomberg was unable or unwilling to include the analysis of respected, independent third party security experts.

Does it matter? The debunking statement will never gain traction with mainstream media.

Bloomberg himself probably has investments with various American merchant banks like Goldman Sachs; take it from their assets

You mean Michael Bloomberg himself? He probably has limited liabilities in the Bloomberg news agency.

Anyway, Huawai must have a case in a Chinese court to begin with. To set an example, all Huawei needs is to find Bloomberg at fault in the court. Compulsory execution will be the job of Chinese court baliffs.

I think the performance improvement they're referring to is the switching time i.e. how fast the circuits, and therefore the overall chip, would work (and reliably at that) compared to that using the earlier process.
