Some of the Ryzen 7000 series CPUs have reportedly seen a change in the PCB, where some of the SMD components on the PCB have been removed.
User Finds Missing Capacitors on the Top Half of Ryzen 7800X3D Substrate; Reports Suggest AMD Made the Changes a Few Months Ago, and the Newer Design Doesn't Affect Operation
It can be terrifying to see visible changes on the CPU, particularly when there have been a lot of cases of fake CPUs circulating in the supply chain. One such instance appeared in front of a user on Chiphell forums, who reported that his Ryzen 7 7800X3D CPU didn't have the SMD components (capacitors) on the top half of the substrate. If you are familiar with 7800X3D's design, you will usually see these capacitors in multiple locations around the IHS, including the top half.
This time, the capacitors were completely missing from the top half, as can be seen from the image. The user contacted AMD, and the company confirmed that they have made some changes to the substrate of the 7800X3D, and therefore, the new design doesn't prove the CPU to be fake. In most instances, there are a lot of changes to the CPU if the CPU is fake, including visible changes in the substrate, IHS, and font. However, the exclusion of capacitors on the top half won't necessarily mean the CPU is fake.
Many users in the thread confirmed the change as well, and one user said this was already implemented several months ago. The newer design with missing components on the top half of the substrate now also includes CPUs like Ryzen 7 7700, and according to more reports, the Ryzen 7600X and Ryzen 7500F may also seem to have those components missing. As per the same user, the change on the Ryzen 7 7700 helped in reducing the local heat buildup, and the CPU can easily boost to 5.0 GHz on all cores much easily.
As far as the 7800X3D is concerned, this isn't the first report. Roughly two months ago, a Reddit user also discovered the same changes and thought it was fake. In both instances, we see the 7800X3D CPUs working normally without any thermal issues or performance drawbacks. The new changes are perhaps to cut the production and testing costs. As removing the top capacitors didn't impact the thermals and performance of the processors, AMD might have decided to completely remove those to enhance the substrate cost optimization.
When this is done across hundreds of thousands of CPUs, the company could save a measurable amount of money. The newer substrate could also bring better reliability, as there will be fewer potential solder defects with the changes. Well, in any case, what matters the most is that the CPU's performance and thermals remain unaffected, and as long as the new substrate doesn't introduce any irregularities, this shouldn't be a concern.
