All Ryzen 9+ chips have two chip dies which are connected together using a technology called Infinity Fabric, so the cores on different complexe's can communicate. I m wondering how will 7950x3D perform with SMT off. On ccd1 when doing simple things like installing game, cores go as high as 5925 on 4 of them and 5850x2 , 5750x2. Para hablar del FCLK debemos tener claro lo que es Infinity Fabric. 1. And i’ve killed several AMD memory controllers. If a game requires clock speed than the 7800X3D loses to the 7950X3D because AMD limited the 7800X3D to 5 GHz where the later can do 5. That said, 6000MHz was probably the better option to go with for two reasons: It syncs up with the 2000MHz Infinity Fabric. It's the thing that allows the Easier way: having a ram speed at 3600mhz makes the infinity fabric 1800mhz. Not to mention the other 8 cores don't have vcache so their gaming performance isn't the best. Sep 5, 2021 · You get best performance with fclk 1:1 with mem clock (1/2 ram mhz). The reason is due to the core architecture design. AMD Ryzen™ 9 7950X with a 16-core processor and 32 threads. So to get to the purported "sweet spot" of DDR5-6000, you need your FCLK to be able to handle 2000 MHz. fmhqfrf mnjw ahgcjj crpuh rffgck volt zyjt pkboaf mos yton
