#Steeven.™ Posted April 10, 2023 Posted April 10, 2023 CPU Model: Ryzen 7 7800X3D Cores/Threads: 8/16 Base/Turbo Frequency: 4.2GHz/5GHz Ryzen 7 7800X3D The Ryzen 5800X3D was a revolution, the icing on the cake of a long-lived AM4 platform that, thanks to its extra cache, showed next-generation performance. As we already mentioned in the analysis of that Zen 3 processor, in this Zen 4 generation we would see processors with 3D V-Cache technology again and, in fact, we now have up to 3 models, the 12 and 16 core processors also have these versions, with 3D cache in a chiplet. The box has a magnetic closure, the front face is a lid that wraps around the box and shows the processor through its central transparency. It does not include a fan, like the rest of the X processors, only the 65W versions include a Wraith Prism. On the back it shows that it is a socket AM5 processor that requires DDR5 RAM. As a novelty we have integrated graphics in Zen 4, with 2 graphics cores and up to 2,200 MHz. The stacked L3 cache employs a highly refined method dubbed by AMD as Hybrid Bond. 3D V-Cache technology unites the third level cache at the molecular level in an evolution of great complexity, with an idea inherited from the first Flip Chip solders. In the Zen 4 we have 32 MB of cache per chiplet, the stacked cache doubles this capacity, obtaining a total of 96 MB in this processor and 128 MB in the Ryzen 9 with 2 chiplets. The AMD Ryzen 7 7800X3D has 8 cores and 6 threads. Its base and turbo frequencies are 4.2 GHz and 5 GHz respectively, the multiplier is locked. This is 300 MHz base and 400 MHz turbo compared to the Ryzen 7 7700X and similar clock frequencies to the Ryzen 7 7700 with less base clock but more turbo. The TDP of the 7700 is 65W, the 7700X is 105W, and the 7800X3D is 120W. The chip is made with TSMC technology and lithography of 5 nm for the cores and 6 nm for the intercom chilpet. The first has a surface area of 71 mm² and the second 122 mm², housing 6.57 billion transistors. The caches per core are 1 MB for L2 and 64 KB for L1. The maximum temperature in the models with 3D V-Cache is 89º, 6 less than in the minus without stacked cache. The stacked cache doesn't just affect the specs, it's a processor that gets hotter, it actually has gold plating on the chiplet for optimal HIS dissipation. To avoid possible problems AMD has not only locked the multiplier but also limited the voltage, but we can activate the PBO and access the Curve Optimizer for adaptive negative voltage compensation. https://www.noticias3d.com/articulo.asp?idarticulo=3547 1
