The $ 449 / £ 429 Ryzen 7 5800X3D is a little different from AMD, a processor that exists to demonstrate the power of the company’s V-Cache 3D design for its upcoming Ryzen CPUs and fight the 12900KS. Intel for the title of “fastest game processor”. ‘. It’s also one of the latest developments for the surprisingly long AM4 platform, which debuted in 2017 and surpassed half a dozen generations of Intel as Ryzen CPUs improved by leaps and bounds.
So what exactly is a V-Cache 3D? Let’s start with the basics. You might think of a processor’s cache as a place to store data that you’re currently working on, a bit like RAM, but because it’s inside the CPU, it’s a faster-magnitude command to access and a command of smaller magnitude in terms of the amount of data it can store. Modern processors typically use three levels of cache: L1, L2, L3, with L1 cache being the fastest to access but the smallest, L2 being slower but bigger and L3 being slower and bigger again. It is this third level of cache that AMD has changed, from a traditional 2D design to a 3D design, a cache stack that takes up more vertical space. This allows much more data to be stored on the CPU at once, thus increasing the chances that the necessary data is already inside and speeding up any further processing.
AMD plans to use this technology for its future Zen 4 processors, but here and now only this special 5800X3D, an updated version of the Ryzen 7 5800X that was launched in 2020. Compared to the 5800X, the 5800X3D sells a one low frequency and some overclocking controls for a significantly larger 96 MB L3 cache: three times the size of the 5800X.

Before we get into the first test results, let’s briefly cover the platform we are using. For the AMD side, we are using an Asus ROG Crosshair 8 Hero, while the 11th generation of Intel gets an Asus ROG Maximus Z590 Hero and the 12th generation gets the Asus ROG Z690 Maximus Hero, all range plates high for their respective platforms. DDR4 motherboards used G.Skill 3600MT / s CL16 memory, while the 12th generation Intel benefited from a faster but more latent Corsair 5200MT / s CL38 RAM.
The 11th-generation AMD and Intel CPUs were cooled with a 240mm AiO Eisbaer Aurora, while the 12th-generation tests were run with an Asus ROG Ryujin 2 360mm AiO. And to answer the obvious question: 240mm and 360mm AiOs usually offer equivalent performance according to our tests, especially for an outdoor test bench in cool ambient conditions (21C). difference is usually the fan speed, which is 240 mm higher than 360 mm.) Our platform was completed with a 1000 W Corsair RM1000x power supply from Infinite Computing.
In order to reduce the variation from run to run and make sure that we are limited by the CPU as much as possible, we use Asus ROG Strix 3090 OC Edition. It’s a massive three-slot, triple-fan design that keeps the card surprisingly cool and quiet.
One of the most important questions about the 5800X3D is exactly where this updated cache will come in handy, because if a game or other application doesn’t fit a specific performance profile, you may not see any performance benefits in running the 5800X3D, and in fact. , may even work worse because of the clock speed that AMD has sacrificed to make the design work.
To find out, we tested the 5800X3D in a number of content and game creation scenarios, against the original 5800X and a number of other recent AMD and Intel processors. We expect to see big increases in performance, especially in video games, but we’ll start with a couple of quick content creation benchmarks: a 3D rendering of Cinebench R20 and a Handbrake video transcoding.

No content creation result is particularly impressive for the 5800X3D, which surpasses the 5600X and Intel 12400F, but lags behind its former competitors such as the 12900K, 12700K and 5800X (the latter between two and six percent) . This is not a massive surprise: none of the tasks will logically benefit from having a larger cache, so you only see the effect of the reduced CPU clocks of the new CPU compared to the standard 5800X. However, the results are not disastrous either; this is still a perfectly capable CPU for these tasks that easily surpasses previous generations, but is not a leader in its class.
