Amazing melon?
Netizens broke the news: Intel plagiarized AMD's chip design and applied for a patent!
PPT to black and white, transformed into patent?
First, let's introduce today's first protagonist, Zen, an x86-64 microarchitecture developed by AMD.
Zen is an important addition to AMD's return to the high-performance computing market, almost completely redesigned and built in new processes to improve performance compared to old architectures, while also introducing a number of new features.
AMD released the first generation of processors based on the Zen architecture shortly after the presentation of the Hot Chips 28 conference in 2016. Its core code name is "Summit Ridge", the official brand name is "Ryzen", and the Chinese name is "Ryzen", and it was officially launched on March 2, 2017.
Another protagonist of the day, Intel's patent numbered US 11,294,809 B2, was approved on April 5, 2022.
Not long after the news was released, Twitter user Underfox found similarities with AMD Zen.
Although the patent is not clearly written, Underfox is convinced that this is Intel's Ocean Cove architecture.
This architecture is the twelfth generation of Alder Lake CPUs, the next generation of Golden Cove. As early as 2018, Intel began research and development.
Underfox says it has been following the work of the Hillsboro team and looking forward to a disruptive new architecture...
However, when Intel's patent was published in 2019, he was completely shocked.
"After analysis, I am very sure that this patent will never be granted in the country where it is proposed."
Although I don't know where his confidence came from, just two days ago, the patent was officially approved.
Estimated to be too much of a blow, Underfox released a series of contrasting images the next day to try to show that Intel was nakedly plagiarized.

Next, let's take a look at how much it looks like.
The above picture shows the Zen microarchitecture released by AMD in August 2016, and the following picture shows the patent obtained by Intel in 2022.
Intel: Not a copy, it's called a "reference."
As soon as the report came out, Intel's spokesperson quickly responded:
When filing a patent application, it is a common practice to cite relevant technologies that exist within the industry. U.S. Patent No. 11,294,809 discloses Intel's innovations in alternative implementations and does not attempt to reproduce or patent the inventions of any other company. Intel Corporation respects the intellectual property rights of all parties.
That is, those "one-to-one" charts are only for "demonstrations", not the basis of patents, and no patents have been filed for any Zen-based technology.
This claim can be corroborated in the citations of the patent, including AMD's August 2016 presentation on Zen architecture at HotChips.
Even, there are well-known media anandtech reports that year.
In any case, Intel has been paying close attention to AMD the whole time when designing the next generation of processors, and it is definitely not running.
WCCFTECH joked that the patent could have been the work of a passionate intern.
however......
After comparing another patent that Intel passed almost 3 years ago, it can only be said that this "intern" has a long career.
In May 2019, a patent called "zeroing a cache line" was approved, which is exactly the same as the "apparatuses and methods for a processor architecture" this time.
However, there are indeed 4 more inventors than the exact same 11 as the last time.

Netizen: The patent is for this idea, not for a specific product
InvincibleBird said, "I personally don't believe Underfox's explanation. It's like saying, 'Brother, this is a prank!' Underfox could certainly have further information about his friend. I believe that if his friend is really a researcher, then he should be happy to share with us some papers he wrote. Of course, this must be the existence of such a friend, not to make up for Underfox to be too humiliating. Also, even if the whole thing is true, I don't think it's very moral."
KarbinCry said, "The patent was not issued to Ocean Cove, but the idea itself, and Zen is just a concrete practice." And I don't think it's really going to work, it's a joke in general."
Shimomura said, "This is Intel's copying method. They have nothing new, they just copy. We knew that when the AMD64 came out. This time it just made me laugh at Intel again. They probably won't have any shame."
I don't know if there are any netizens who are more familiar with this field, can you answer it?
