AMD Ryzen 5800X3D Review: New Gaming CPU ‘King’ Yielded with 3-D V Cache

amd ryzen 7

The AMD Ryzen 7 5800X3D is a brand new 5000 series CPU from AMD. It could be considered as an upgraded refresh over the already existing 5800X. Having the same barebones specifications as 5800X (except the cache), there are some cases in which it can outperform AMD’s flagship Ryzen 9 5900X and Intel 12th generation 12900k, in terms of gaming performance. The new addition in the Ryzen 7 lineup outperforms the flagship CPUs in the market, due to 5800X3D’s new AMD 3D V-Cache technology, which triples the CPU’s L3 cache from 32MB to 96MB. This technology enhances cache capacity, while maintaining access speed. As we’ve seen projections against AMD and Intel’s current flagship CPUs (5900X and 12900K), it appears to be a favorable contender.

The specs of the Ryzen 7 5800X3D are as follows: 

  • 8 cores 
  • 16 threads
  • Boost clock: 4.5GHz 
  • Base clock: 3.4GHz
  • L1 cache: 512KB
  • L2 cache: 4MB
  • L3 cache: 96MB
  • Default TDP: 105W
  • Socket: AM4

Cache and 3D V-cache

To understand this we need to know a few things about cache and its levels, 3D cache and what it does for a CPU. One can understand cache as a medium to bridge the gap  between the CPU and RAM. Generally, the more cache you have, the better it is .This allows us to have faster and more efficient access to information stored in the system’s memory. A CPUs cache has three levels.

  • Level one cache is located closest to the CPU’s cores and has fast access speeds, but also the smallest capacity. This is reserved for the data that is most frequently accessed by the CPU.
  • Level two cache is a middle ground, with median capacity and the median speed, reserved for the less important data, but it is still an integral and ideal entity to ensure that the CPU has fast access to level two cache. 
  • Level three cache stores most of our frequently accessed data such as programs and execution paths. This has the largest capacity in comparison to the other two levels, but is also many magnitudes slower than caches at higher levels. It has the greatest capacity, and hence can store larger fragments of data.

The 64MB of additional L3 cache is stacked physically on the Zen 3 CCD and connected with direct copper-to-copper bonding. It results in a large pool of L3 caches that can be treated equally by the system—the 64MB of stacked cache isn’t an L4 cache, and the 32MB of L3 cache built into the CCD doesn’t have any performance advantage compared to the cache stacked on top.

The 5800X3D has a slower clock speed than its predecessor. AMD is pushing the 5800X3D mainly as a gaming processor since a larger cache pool helps games run more smoothly and is consistently used. Motherboards that support other Ryzen 5000 CPUs will work with the 5800X3D, but they won’t be able to access the extra cache. 

In combination with the Zen 3 architecture and much larger L3 cache, AMD promised that there would be a 15% boost in gaming performance with its 3D V-cache. There were many instances where increasing the L3 cache of a 10th-gen Core series processor from 12 to 20 MB (a 67% increase) could boost gaming performance by around 20%, whereas increasing the core count from 6 to 10 cores (also a 67% increase) would only improve performance by 6% or less. In other words, the best way to boost the performance in today’s games is by making the cores faster rather than adding more of them. 

Taking this into consideration, AMD has opted to supercharge their 8-core, 16-thread Ryzen 7 5800X with 3D V-cache, creating the 5800X3D. AMD says the 5800X3D extra cache enables it to outperform Intel’s fastest CPUs in gaming.

The Ryzen 5 5800X3D has much more L3 cache and the same amount of L2 and L1 cache capacity. However, the cache architecture is based on a vertical composition which allows it for more cache modules, along with greater access speeds. 

Core speeds 

The Ryzen 7 5800X has a base core speed of 3.9GHz and a boosted core speed of 4.7GHz, while the Ryzen 7 5800X3D boasts a base of 3.4GHz and a boost of 4.5GHz. 


Both of the CPUs have a TDP of 105W. 


Both the CPUs are based on the AM4 socket. 

Thread count 

Both the 5800X and the 5800X3D have the same thread count. Both of the CPUs support SMT (Simultaneous Multithreading). This is a technology that allows one CPU’s core to process and execute two instructions simultaneously. The technology binds 2 threads to a single core, hence whenever a task from a single thread is successfully executed, it doesn’t have to wait for the thread to fetch the next task. SMT splits each of CPU’s physical cores into virtual cores, which are known as threads. They are so-named because they do not physically exist or occupy space on the CPU.


Core count 

Both  5800X and 5800X3D have the same number of physical cores. Higher the core counts, the more efficient the CPU will be in multitasking but it all depends on whether the software you’re using supports it or not.


Starting with general-purpose CPU testing,it is noticeable that the 5800X3D is outperformed by the ordinary 5800X in addition to the Core i7-12700 and Core i9-12900 models, which have more cores. While the 5800X3D offers overclocking and power consumption controls, it has slightly slower clock speeds than the 5800X. The 5800X3D would prove to be least advantageous if you are working on an app that does not care much about the cache size.

Here are some benchmarks


An 18% increase for the average frame rate at 1080p and a 24% boost to 1% slows and similar figures were also seen at then the 5800X3D will probably appeal to you.

Power Consumption and Cooling:-

The 5800X3D uses less power than the 5800X by approximately 15%. The major contributing factor towards  this can be that it probably uses higher quality silicon. The considerable difference seen in this Ryzen CPU is that it has a locked CPU multiplier, unlike its comparable counterpart. 

If your computer has a faster RAM, the 5800X3D could also run a little bit better, because doing this will boost both your RAM bandwidth and AMD’s Infinity Fabric interconnect’s performance. For anyone who works with heavy photo and video editing tools or does streaming PC, the 5800X3D isn’t much impressive as compared to other CPUs that fall in the range of  $300 to $500 price. Observations say that 58000X3D  edged out the 12900K when both were using DDR4 memory. High speed DDR5 does give the Core I9 processor an advantage , but it’s also very expensive. 

Availability and price of the CPU, however, is a major factor in determining its worth. The performance metrics are as good as art displays if the actual hardware is missing from store shelves. Although, this new approach might bring significant advancements in the coming future not only for gamers, but other users as well.
