AMD Ryzen 9 7900X3D Desk-top Processor (12-core/24-thread, 140MB cache, up to 5.6 GHz max boost)

Product Information

So I did a CMOS Clear (turn off PSU switch, hold Clear CMOS for 5 seconds, then apply power again and boot), it trained and straight in to the BIOS.

I've been doing more CO Undervolting tests last night and actually the only time I've had C5 is Ryzen Master, when it reboots to do reset / change something in the BIOS it always C5's. However, nothing I set EXPO I / EXPO II myself ever caused a C5, just retraining, it's seemingly quite stable, the only crashes have been when doing CO offsets < -30 on some cores but nothing that looks memory related at all. I had this when messing with MCLK settings and had enabled 'Memory Context Restore' which I then had to CMOS Clear to reset. Overall, no one will be disappointed with this chip's performance, however pretty much everything else is a better option, I am overall happy with the chip however I do have some buyers remorse as the alternatives either, perform better or cost less and potentially in the case of the 7800X3D - both!Ultimately, the reduced memory latency means that you're getting a chip that runs cooler, draws less power, and performs better thanks to the addition of the second generation of AMD's V-cache. Touch wood, after stopping messing and having done a CMOS Clear, it seems to be fairly stable (no issues playing games for about 8 hours so far). The latest CPUs in the AMD Ryzen 7000 Series are here. Teased at CES 2023, the X3D Ryzen 9 models are finally hitting the shelves!As of April 6 th, we now also have an X3D Ryzen 7 model too! As for the chip’s release date, now we know that it’s February 28th, it’s interesting that both Ryzen 9 X3D chips will arrive before the Ryzen 7 7800X3D debut, which was previously reportedly set for February 14th, before AMD denied that date while committing to February for the launch of the X3D.

Problem 2 - The Design: Due to the design of the chip only having the 3D v-cache on one of the two CCDs, core parking during gaming workloads is applied, meaning 6 cores and 6 threads are deactivated so you're only utilising the 6 cores and 6 threads that hold the 3D v-cache while gaming. When the 7800X3D launches that CPU only have 1 CCD which holds all the 3D v-cache meaning all 8 cores will be available during gaming. No doubt the 7800X3D will be popular, and releasing six weeks after the two Ryzen 9 processors may allow the top-tier to stretch their legs a little. But a lot will depend on performance, especially given the ongoing battle between Zen 4 and Intel’s Raptor Lake processors.

I tested the AMD Ryzen 9 7900X3D inside of a newly built machine utilizing Kingston Fury Beast DDR5 RAM, an Nvidia RTX 4090, and a brand new RM1000X PSU. The chip was utilized heavily for gaming in the benchmarked titles as well as in games such as Mortal Kombat 11, Cyberpunk 2077, and Tekken 7. Compared to the more expensive chipsets, the AMD Ryzen 9 7900X3D absolutely holds its own with the 7950X3D and the 13900K, with the largest gap visible seen with how AMD's flagship handles Returnal. This is likely due to the fact that the 7950X3D utilizes an additional four cores and eight threads, and Total War series has always been Intel's strongest gaming benchmark, which remains the case here. The Ryzen 9 7900X3D has also been crafted for high-performance gaming and creating. Its cache capacity is 140MB, paired with twelve cores, twenty-four threads, and boost speeds up to 5.6GHz. The much-anticipated Ryzen 9 7900X3D was first unveiled only recently amid CES 2023, wherein some of the most mind-bending new technologies gain traction and become icons in the fold. As for the Ryzen 9 7900X3D release date, little was known until now.

While a higher TDP usually relates to higher performance, the inclusion of the added 3D V-cache means that the processor can access a larger pool of superfast cache memory, which is even more useful when gaming than just throwing raw power at the problem. With its own dedicated extra cache, there are fewer fetch operations to the PC's main memory, so the chip runs more efficiently, and potentially cooler under load.

The higher the L3 cache is, the better gaming or intensive processing workloads can perform, that's because it's the largest level of cache available on a processor. AMD’s CES keynote highlighted the continued innovations the firm is set to utilize in 2023, the most prominent among them being the upgrading of its 3D V-cache technology, which will be implemented in three new chips. It’s not far off, the Ryzen 9 7900X3D release date will be February 28th.
