For its final push in the “Zen 3” era, AMD introduced the Ryzen 5000 series, a new line of high-performance desktop and mobile processors. The Ryzen 7 5800X3D topped the list of new chips announced by the business. The Ryzen 7 5800X has been reworked into an octa-core version of this new CPU. Comparing the AMD Ryzen 7 5800X vs. the Radeon HD 7870 in this article will help you determine which processor is best suited for your upcoming PC setup.

What is a 3D V-cache?
The new Ryzen 7 5800X3D takes advantage of AMD’s 3D V-cache, one of the biggest distinctions between the two chips. For those who don’t know, the cache can be thought of as the system’s additional RAM. For rapid and easy access to a portion of storage, cache memory serves as a backup store of sorts.
3D V-cache differs from the normal 2D cache found in most CPUs in that it is stacked vertically. Chiplets can only be added to single processing die in this way. With vertical stacking in the 3D cache, this is no longer the case. The number of chiplets that may be added with this configuration is greatly increased, resulting in a larger cache.
The new Ryzen 7 5800X3D has 96MB of L3 cache, compared to 32MB of L3 cache in the previous 5800X. Just by taking advantage of the increased cache capacity, AMD claims that the new processor gives a considerable performance improvement over the previous chip. If that notion holds up, we’ll be interested to see how some of the other chips on the market measure up. As a next step, let’s look at the technical details for each of the CPUs involved in this matchup:
AMD Ryzen 7 5800X vs Ryzen 7 5800X3D: Specifications
Specification | AMD Ryzen 7 5800X | AMD Ryzen 7 5800X3D |
---|---|---|
Cores | 8 | 8 |
Threads | 16 | 16 |
Base clock | 3.8GHz | 3.4GHz |
Max. Boost clock | Up to 4.7GHz | Up to 4.5GHz |
L3 cache | 32MB | 96MB |
Default TDP | 105W | 105W |
Max. Operating Temperature | 90°C | 90°C |
Unlocked for overclocking | Yes | No |
CPU socket | AM4 | AM4 |
Performance Difference
Eight cores and sixteen threads are present in both the Ryzen 7 5800X3D and the Ryzen 7 5800X2. It is true that both CPUs use the Zen 3 architecture. Because of this larger L3 cache, it is believed that the new Ryzen 7 5800X3D with 3D V-cache will perform significantly better than the older CPU due to its increased clock speed. Overall gaming performance is likely to benefit greatly from the added L3 cache.
Just increasing the cache memory, according to AMD’s internal testing, has resulted in a 40 percent increase in performance over the Ryzen 7 5800X. With the inclusion of cache RAM, AMD claims to have made a “generational leap” in gaming performance. AMD claims that its Ryzen 7 5800X3D processor is currently the world’s fastest gaming processor. So, it’s possible that it’s even better than Intel’s Core i9 12900K chip, but we won’t know for sure until we’ve tested it out. Read more; Intel Vs AMD: Which CPUs are Better in 2022
However, when compared to the new processor, the Ryzen 7 5800X has quicker cores. The AMD Ryzen 7 5800X has a base core speed of 3.9GHz and a boost core speed of 4.7GHz, as shown in the specifications table. A base frequency of 3.4GHz and a boost clock of 4.5GHz are found in the Ryzen 7 5800X3D. The new processor, despite its slower cores, is expected to outperform the Ryzen 7 5800X. To put it another way: AMD’s own tests show that the new processor outperforms even AMD and Intel’s most powerful CPUs. Take a look at this –

No overclocking support?
Additionally, the Ryzen 7 5800X3D does not have overclocking capabilities. There’s been a lot of discussion over this, but it doesn’t appear like the new chip can be overclocked. This could be due to a lack of heat dissipation. Stacked dies may make it more difficult to cool the chip underneath. To see how far these chips can go, we may have to wait till we get our hands on one.
If you want to overclock the AMD Ryzen 7 5800X, you should be able to because this CPU is completely unlocked for overclocking. Even though they both have a maximum operating temperature of 90°C, the Ryzen 7 5800X and the Ryzen 7 5800X3D do not come with a default CPU cooler.

Availability and Pricing
The Ryzen 7 5800X3D CPU’s pricing and release date have been officially announced by AMD. The price is $449, and it will be available for purchase on April 20. The Ryzen 7 5800X debuted at the same pricing as this model. As opposed to this, the Ryzen 7 5800X is now available for roughly $350 and is readily available on the market right now.
Exactly which one should you buy?
At $359, the Ryzen 7 5800X is suddenly approximately $100 more expensive, and that’s before you consider the cost of a CPU cooler. How much of a difference does it make to upgrade? According to AMD’s benchmark data, this appears to be a decent gaming processor. However, unless you’re building a high-end enthusiast rig, we believe the $359 price tag on the Ryzen 7 5800X makes it a sound investment. Additionally, AMD’s new Ryzen 7000 series CPUs will be available in a few months, and they’ll be powered by the new Zen 4 architecture, which promises increased performance and new capabilities.
