AMD Ryzen 7 5800X3D tested two weeks before launch


The Ryzen 7 5800X3D tested two weeks before the launch date of April 20. The 5800X3D has been the cause of a lot of excitement in the CPU space this year since its announcement at CES 2022. It’s not exactly a brand new processor, more than it is a rehash of an older favourite the 5800X. The innovation here comes from AMD’s 3D V-cache technology, stacking 64MB of 3D cache right on top of the CPU chiplet itself. 

If you’re interested, we have a 5800X vs 5800X3D article. that explores the performance of each CPU in detail.

AMD has claimed that 3D V-cache gives the 5800X3D a significant advantage over CPUs like the 5900X and the 12900k, showing data suggesting the 5800X3D outperforms them in some scenarios by up to 15%, despite the sacrifices that had to be made to its base and boost clock speeds. These are some big claims by AMD and we will be able to substantiate them ourselves when it’s released. 

It makes you wonder just how XanxoGaming got hold of a 5800X3D so far away from launch? Well, as it turns out, it’s pretty simple to just buy this CPU in Peru right now. It’s also worth mentioning that AMD once blacklisted XanxoGaming, denying them access to review samples. 

Ryzen 7 5800X3D: Benchmarks

The system that the 5800X3D was tested on was an X570 Gigabyte Aorus Master motherboard with BIOS update F36C installed. This motherboard, along with many others, was recently optimized for the 5800X3D in the form of a BIOS update. The rest of the system was built with 16GB of DDR4-3200MHz RAM and an RTX 3080 Ti GPU, all tested on Windows 10.

XanxoGaming tested the Ryzen 7 5800X3D in Geekbench, CPU-Z, Cinebench and Blender respectively. 

Ryzen 7 5800X3D Geekbench 5

In Geekbench 5.4.4 for Windows, the 5800X3D scored 1,639 in single-core and 10,498 in multi-core benchmarks respectively. This is actually a lower single-core score than its predecessor, the 5800X, probably due to its reduced core speeds.  
The 5800X managed to score 1,671 in single-core and 10,339 in multi-core tests according to the Geekbench database. 

Ryzen 7 5800X3D CPU Z

In CPU-Z, AMD’s 5800X3D scores a mediocre 617 and 6506 points in CPU-Z’s in-built benchmark. This is lower than the reference data for the 12900K, Videocardz reports. 

Ryzen 7 5800X3D Cinebench R23

However, in Cinebench, the result is slightly more promising. The 5800X3D scores 1,493 points in the single-core benchmark and 15060 in the multi-core benchmark. That’s between 3.5% to 12% better performance than the original 5800X (there’s not enough data to give a more accurate answer).  

You can find more Blender tests in the original review. According to the author, more results will be added soon. These include 1080P gaming benchmarks and comparisons to the 12900KF, so check back later. 

Final word

The results aren’t looking too good for the 5800X3D according to synthetics, but it’s important that we don’t judge it too harshly before we see the bigger picture and its performance in real-world scenarios. The CPU should not have been benchmarked yet as we’re still a little way off the launch date, and there could be some last-minute optimizations to be made. 

But thanks to the 3D V-cache being unstable at higher core speeds, overclocking support has been removed completely. We’re unclear on what this means right now – will there be PBO or not? But whatever the case, the lack of overclocking gives it a serious disadvantage. We definitely wanted better for the last CPU of the legendary, industry-changing AM4 platform. 

We will be happy to hear your thoughts
