![]() ![]() ![]() To check the operating temperatures, I run Blender instead of Prime95 and small FFTs, which apply an unrealistically high load to the CPU.Īccording to AMD, the 7000 series can run all day at 95C without any issues. New Chipsetsīesides power consumption, I also look at the energy usage of each CPU to see how efficient they are by calculating the total amount of power required to finish two tasks, a Super Pi run indicative of single-threaded applications and a Cinebench run for multi-threaded scenarios. The XPG RAM ( Caster 6400) I will use in this review includes EXPO profiles, so I will have the chance to try them out. Moreover, this is an open standard, so I expect most RAM manufacturers to adopt it soon. Compared to XMP profiles, the EXPO ones offer settings unique to AMD CPUs. These RAM speed profiles offer a convenient way to achieve high RAM speeds without sweating. AMD states that DDR5-6000 is the “sweet spot,” so I changed my test system’s DDR5 RAM with an XPG DDR6400 kit.Ī new overclocking profile called EXPO (Extended Profiles for Overclocking) is available, especially for AMD CPUs. You use AUTO settings for FCLK and the memory controller at 1:1 with the DRAM’s frequency. While in the previous generation, you had to keep the Infinity Fabric clock speed (FCLK), the memory controller (UCLK), and the memory clock (MCLK) at the same speeds, this is not the case anymore. With the exclusive support of DDR5, RAM overclocking is an entirely different story. I won’t go into more detail about the Zen4 architecture since it’s been covered extensively already. The execution engine and the L2 cache follow in improving the performance of the new processors. The front end, load/store, and branch prediction parts bring most of this performance gain. In general, all improvements on the Zen4 bring up to 13% IPC improvement, according to AMD’s claims. This scheme shows the features of the Radeon 610 iGPU that the AMD Zen4 CPUs utilize. ![]() The embedded GPU is not for gaming purposes, and I guess most will buy such a powerful processor to combine it with a capable graphics card. The new IOD also includes a dual-channel DDR5 memory controller with ECC support. This and several other changes required lower 6nm lithography than the 12nm that the previous-gen cIOD used. The new I/O die finally packs an RDNA2 iGPU. Another interesting feature of Zen4 is the support for AVX-512, which increases the AI performance. AMD Zen4 DetailsĬontrary to Intel, all cores in the AMD Zen4 are the same, so there is no distinction between performance and efficiency cores, which can confuse the software. The good news is that despite the new socket, there is compatibility with the existing AM4 coolers, so you won’t have to search for a new cooler or adapter bracket to use your old one. Finally, no more bent CPU pins, but you should be careful with the pins on the mainboard. The new socket is powerful and capable of delivering up to 230W by utilizing a land-grid array (LGA), similar to what Intel has been doing for quite some time now. After five years that the socket AM4 has been with us, we have a new socket, named AM5 (what a surprise!), supporting DDR5 memory and PCIe Gen 5 for both storage and graphics at the same time. With the release of AMD’s new Ryzen 7000 Zen4 series processors, with the codename Raphael, we have some significant changes from the Red team. On top of that, it needs a strong PSU, if you pair it with a potent GPU, since I measured up to 227W power power consumption. This CPU is designed to run hot, so 95☌ should not trouble you. It doesn’t matter what you will throw at it, games or applications, it just won’t budge.
