AMD’s upcoming line of 7000X3D processors, which incorporates the Ryzen 9 7950X3D, Ryzen 9 7900X3D and Ryzen 7 7800X3D, promise wonderful gaming efficiency due to copious quantities of 3D V-Cache. Nevertheless, these new processors apply the cache to solely one of many two CCDs (opens in new tab) (Complicated Core Dies) that make up the chip structure so your software program and firmware have to make it possible for video games make the most of the proper CCD otherwise you will not get the efficiency advantages. For non-gaming duties, the CCD with out cache might be a better option as it may possibly hit greater enhance clocks.
On the subject of assigning duties to cores (or CCDs), each the OS and the firmware can generally make errors, sending precedence workloads to slower threads. Luckily, it’s possible you’ll quickly have the ability to tweak the CCD precedence in your BIOS, permitting you to have fine-grain management over which cores get which duties in a manner that is unbiased of the OS.
Twitter person HXL (@9550pro) has shared display pictures (opens in new tab) from a brand new Asus X670 Beta BIOS (model 0921 to be exact) that present quite a few superior settings you should utilize to regulate the X3D cores. These photographs seem to have first s (opens in new tab)hown up on Asus’ boards. These settings embrace quite a few completely different algorithm circumstances and actions that may set off the proper CCD core. HXL notes that, since these settings are constructed into the BIOS, they’re OS agnostic.

These tweaks are vital for non-gaming workloads as a result of, as we reported yesterday, the Ryzen 9 7950X3D specifically is rumored to have decrease frequencies on its V-Cache CCD than the cheaper 7800X3D has. The 7950X3D has eight cores in every of its two CCDs.
AMD has additionally gone on document saying that the non-V-Cache CCDs can obtain greater clocks. In an interview with PC World (opens in new tab) in January, AMD director of product administration Scott Stankard mentioned that “by not stacking one of many CCDs, it allow us to push the 1T enhance, the utmost T enhance, as much as 5.7 GHz.”
|CPU||Cores / Threads (P+E)||P-Core Base / Enhance Clock (GHz)||Cache (L2/L3)||TDP|
|Ryzen 9 7950X3D||16 / 32||4.2 / 5.7||144MB (16+128)||120W|
|Ryzen 9 7900X3D||12 / 24||4.4 / 5.6||140MB (12+132)||120W|
|Ryzen 7 7800X3D||8 /16||4.x / 5.0||104MB (8+96)||120W|
Extra particulars and hyperlinks to a obtain for the beta BIOS can be found in this thread (opens in new tab) on Asus’s ROG discussion board. Nevertheless, we do not advocate attempting a beta BIOS, notably when the chips themselves will not be accessible till February 28. Moreover, these recordsdata are in a Dropbox linked from a discussion board, not an official supply. For the sake of your machine’s safety, maintain off till one thing official is obtainable.
What we will glean from this information is that many, if not all, X670 motherboards, together with among the greatest motherboards will quickly get BIOS updates that assist you to fine-tune which workloads get assigned to which CCD. Maybe different chipsets comparable to B650 will see these advantages as effectively. If you find yourself needing one in every of these, see our tutorial on tips on how to replace the BIOS on a PC.
