recently Gigabyte hacking incident A week ago, the attackers stole 112GB of data from Gigabyte servers. This includes confidential documents of upcoming products and information shared under NDA and contracts.Today, according to a new ReportAfter the hacker posted the file online, information about the AMD EPYC processor (code-named Genoa) appeared. According to leaked information, these chips have 96 cores and support 12-channel DDR5 memory, which also marks the first time that AMD’s lineup supports AVX-512.
Gigabyte’s life is not easy: from Power RMA crash With the recent hacking incident, the situation has worsened. The attacker who stole 112GB of data from Gigabyte servers has released some information and some details about AMD’s upcoming EPYC Genoa CPU micro-architecture.
Previously, we thought that Genoa was a 96-core design, and it turned out to be so. Leaked documents show that Genoa is still composed of 8-core CCDs, but now there are 12 Zen 4 IPs with a total of 96 cores and 192 threads. The platform hosting this large processor is AMD’s SP5, as shown in the figure below.
A particularly interesting fact is that AMD decided to pair 12-channel DDR5 memory with Genoa to provide a lot of bandwidth for all 96 cores for normal operation. Given that so many cores require extremely high speeds, a 12-channel controller is sufficient. In addition, Intel’s AVX-512 seems to make its debut in AMD processors. The leaked document shows the appearance of the EVEX instruction in Genoa, which is actually an AVX-512 type instruction, indicating that the AVX-512 engine is used in these new processors.
Another interesting tidbit of the leak is the assumed power consumption and power configuration. The highest-end SKU should have a TDP of 320 watts and a maximum power consumption of 400 watts. For 1 millisecond (ms), the CPU can consume 700 watts, so the server power supply will require additional breathing room.

Information about the scope of the TDP has also been shared, revealing most of the secrets surrounding the Genoese chip powered by Zen 4. The hacked information is very extensive, and several entities are currently combing it to obtain more information. stay tuned.
