AMD Ryzen 7 5800X3D: The World’s First CPU With 3D V-Cache Specs, Price, Performance & Availability – Everything You Need To Know

AMD Ryzen 7 5800X3D will be the latest addition to the Zen 3 powered Ryzen 5000 Desktop CPU lineup and is coming to the AM4 platform this Spring. The CPU is definitely a major technological marvel with its bleeding-edge 3D V-Cache technology so let's take a look at what to expect & what you should know about this chip.

The real Ryzen update isn't scheduled till the second half of this year. As such, AMD had decided to offer an intermediary solution to gamers who want better performance on their existing AM4 CPU platforms. As such, the Ryzen 7 5800X3D will be the first major update for desktops when it comes to retail in the coming months. So let's talk about what we know so far about this CPU product and what consumers can expect from it.

AMD Ryzen 'Zen 3D' Desktop CPU Expected Features:

Now as to why the Ryzen 7 5800X3D is the only 3D V-Cache CPU option that AMD is going to offer, it is explained that 8 cores offer the perfect and most balanced gaming performance so it made the most sense to uplift the Ryzen 7 5800X with 3D V-Cache and offer a product that most mainstream gamers can have access to.

In terms of specifications, the AMD Ryzen 7 5800X3D will offer 8 cores and 16 threads within a single CCD. It will rock a base clock of 3.4 GHz & a boost clock of 4.5 GHz which is slightly slower than the 4.7 GHz of the Non-3D Ryzen 7 5800X. The CPU will feature a TDP of 105W which is the same as the Ryzen 7 5800X. The CPU is also not expected to offer any overclocking support and this is due to the fact that the SRAM cache can only operate up to 1.35V so overclocking the processor beyond this can damage it permanently.

The main difference between the two chips is the amount of cache. The AMD Ryzen 7 5800X3D will carry 32 MB of L3 cache on-die and 64 MB of cache off-die within the vertical stacks. The CPU will feature a single 3D V-Cache stack that incorporates 64 MB of L3 cache and sits on top of the TSV's already featured on existing Zen 3 CCDs. This will give a total of 96 MB L3 cache directly to the Zen 3 cores.

AMD has thinned out the Zen 3 CCD and the V-Cache so they have the same Z-height as the current Zen 3 processors rather than varying heights between the cores and the IOD. Since the V-Cach sits on top of the CCD L3 cache, it doesn't affect the heat output of the core and has minimal power up-ticks. It is also explained by AMD that while frequency is important, most games are very latency-sensitive so adding more cache was the most practical choice. Also, the benefits of having the extra cache overweighs the frequency degradation so while that tradeoff had to be made, the chip still has better performance to offer over the standard Ryzen 7 5800X CPU.

Furthermore, the AMD Ryzen 7 5800X3D CPU is compatible with a full range of AMD 400 and 500-series motherboards. Each motherboard maker has shipped out their respective BIOS support for the chip already.

When it comes to performance, AMD has shown has comparative performance numbers against both, its fastest Ryzen 5000 gaming CPU and also Intel's fastest 12th Gen Alder Lake Gaming CPU.

Versus the AMD Ryzen 9 5900X, the Ryzen 7 5800X3D offers up to 40% performance gains and a 15% average uplift at the 1080p High configuration across several titles. There will be titles that don't utilize the 3D V-Cache fully but based on what's shown, the Ryzen 7 5800X3D does look like an incredible performer in its category.

Versus the Intel Core i9-12900K, the Ryzen 7 5800X3D shows up to 20% gains and also ties against Intel's fastest Alder Lake CPU. This is while the chip runs at a 700 MHz lower clock speed (12900K 5.2 GHz single-core boost). The 1080p High preset is used across all titles tested and there are a series of titles that the Ryzen 7 5800X3D ties with the 12900K. The main takeaway is that the AMD chip will cost less and can be upgraded to on the same AM4 platform while Intel's path requires a brand new platform and a chip that costs over $500 US.

Still, these are preliminary benchmarks and the differences at higher resolutions will be more or less lower than what's shown here since that's more of a GPU bound scenario. With that said, we can't wait to get our hands on this chip and test it out ourselves.

As for pricing and availability, the A. According to the details, the AMD Ryzen 7 5800X3D will be launching on the 20th of April for a price of $449 US.

The AMD Ryzen 7 5800X launched at an MSRP of $449 US but that was back in 2020. Currently, the chip sells for a discounted price between $299-349 US so it looks like AMD isn't offering disruptive pricing with its first 3D part, and it's rather priced more than the Core i7-12700K. Again, this would be better pricing than the Ryzen 9 5900X and Core i9-12900K if you're solely looking for faster gaming performance but other than that, those two options will be worth better if you plan on using the multi-threading capabilities of the CPU.
