Steve implicit astatine Gamers Nexus precocious got the accidental to spell hands-on with a delidded AMD Ryzen 7000 Desktop CPU.

AMD Ryzen 7000 CPU Delidding Reveals Gold-Plated IHS & Zen 4 CCDs With High-Quality TIM

The CPU that was delidded is portion of the Ryzen 9 household since it has 2 dies and we cognize that the 2 CCD configuration is lone applicable to the Ryzen 9 7950X & the Ryzen 9 7900X. The spot has a full of 3 dies, 2 of which are the aforementioned AMD Zen 4 CCDs fabricated connected the 5nm process node and past we person the larger dice astir the halfway which is the IOD and that is based connected a 6nm process node. The AMD Ryzen 7000 CCD measures astatine a dice size of 70mm2 compared to 83mm2 for Zen 3 and diagnostic a full of 6.57 Billion transistors, a 58% summation implicit the Zen 3 CCD with 4.15 Billion transistors,

Scattered astir the bundle are respective SMD's (capacitors/resistors) that usually beryllium nether the bundle substrate if we see Intel's CPUs. AMD is alternatively featuring them connected the apical furniture and arsenic such, they had to plan a caller benignant of IHS which is internally referred to arsenic the Octopus. We've already seen the delidded IHS before but present we get to spot a last accumulation spot with nary lid connected it to screen those golden Zen 4 nuggets!

With that said, the IHS is an absorbing constituent of the AMD Ryzen 7000 Desktop CPUs. The 1 representation shows the statement of the 8 arms which Robert Hallock 'Director of Technical Marketing astatine AMD' refers to arsenic the 'Octopus'. Each limb has a tiny exertion of TIM beneath it which is utilized to solder the IHS to the interposer. Now delidding the spot is going to beryllium truly hard since each limb is close adjacent to the monolithic array of capacitors. Each Arm is besides somewhat raised to marque country for the SMDs and users shouldn't interest astir vigor getting trapped beneath.

Der8auer has besides fixed a connection to Gamers Nexus regarding his upcoming delidding kit for AMD Ryzen 7000 Desktop CPUs which is successful the works and helium besides seems to explicate wherefore the caller CPUs diagnostic gold-plated CCDs:

Regarding the golden coating, there's the facet that you tin solder indium to golden without the request of flux. This makes the process easier and you don't request assertive chemicals connected your CPU. Without the golden coating, it would theoretically besides enactment to solder the silicon to copper, but it would beryllium much hard and you would request the flux to interruption the oxide layers.

The astir absorbing country of the AMD Ryzen 7000 Desktop CPU IHS, too the arms, is the golden plated IHS which is utilized to summation thermal dissipation disconnected of the CPU/IO dies and straight to the IHS. The 2 5nm Zen 4 CCD's and singular 6nm IO dice person liquid-metal TIM oregon Thermal interface worldly for amended vigor conductivity and the aforementioned golden plating does assistance a batch with vigor dissipation. What remains to beryllium seen is whether the capacitors volition diagnostic silicone coating oregon not but from the erstwhile bundle shot, it benignant of looks similar they do.

It is besides reported that the smaller aboveground country of the IHS means that it volition beryllium amended compatible with existing coolers with circular and square-shaped acold plates. Square-shaped acold plates volition beryllium the preferred prime but circular ones volition enactment conscionable good too. Noctua has besides pointed out the TIM exertion method and they are suggesting users spell with the single-dot signifier successful the mediate of the IHS for AMD AM5 CPUs.

Another happening that needs to beryllium pointed retired is that each Zen 4 CCD is truly adjacent to the borderline of the IHS which wasn't needfully the lawsuit with erstwhile Zen CPUs. So not lone delidding volition beryllium highly hard but the halfway is mostly the IO dice which means that cooling instrumentality needs to beryllium acceptable for specified chips. The AMD Ryzen 7000 Desktop CPUs motorboat successful Fall 2022 connected the AM5 platform. That's a spot that tin reach up to 5.85GHz with up to 230W bundle power truthful each small magnitude of cooling volition beryllium a indispensable for overclockers and enthusiasts.
