AMD's Ryzen 7 5800X3D lacks overclocking support

Today, rumours started to circulate about the overclockability of AMD's soon-to-be-released Ryzen 7 5800X3D processor, as a source on Bilibili, a Chinese social media platform, stated that the CPU does not support overclocking.

Based on information that AMD has already released about their Ryzen 7 5800X3D processor, we can confirm that these claims are legitimate. Even AMD's website doesn't list their Ryzen 7 5800X3D as overclockable, unlike the company's other Ryzen 5000 series processors. Just look at the image below. 

AMD's Ryzen 7 5800X3D enhances AMD's Zen 3 architecture by adding additional L3 cache to the processor, giving the CPU 96MB of L3 Cache. This cache is three times larger than the Ryzen 7 5800X's 32MB L3 Cache, and that cache has the potential to significantly increase AMD's gaming performance. 

How AMD's L3 cache impacts gaming performance will change on a game-by-game basis. Enlarging their L3 cache allows more data to be held on-chip, allowing important data to be access faster. This upgrade allows AMD's Ryzen 7 5800X3D to start working faster, increasing overall system performance.

In gaming tests, AMD has estimated tha their Ryzen 7 5800X3D is 15% faster than their Ryzen 9 5900X (their current fastest gaming processor) on average. At CES, AMD showcases performance gains of between 9% and 36% across a selection of games (source).

Is AMD's Ryzen 7 5800X3D slower than its predecessor in some workloads?

As you can see below, AMD's Ryzen 7 5800X webpage clearly lists overclocking support. Beyond that, it also reveals that the Ryzen 7 5800X has higher base and boost clock speeds than its V-Cache enhanced successor. 

AMD's Ryzen 7 5800X3D has a base clock speed that is 400MHz slower than their Ryzen 7 5800X, and a boost clock speed that is 200MHz slower. That said, AMD's V-Cache addition should increase performance enough for the Ryzen 7 5800X3D to deliver higher performance levels in many workloads. That said, workloads that aren't cache sensitive may see slight performance degradations.

What's important is that AMD believes that their addition of V-Cache is worth these minor clock speed degradations. That said, these clock speed decreases make the Ryzen 7 5800X3D's apparent lack of overclocking support all the more disappointing. 

What about Precision Boost Overdrive? 

At this time, AMD has not confirmed whether or not their Ryzen 7 5800X3D supports Precision Boost Overdrive, a feature that could allow users of AMD's V-Cache enhanced Ryzen CPU to increase the average clock speeds of their processor. Hopefully Precision Boost Overdrive will be enabled for AMD's Ryzen 7 5800X3D, as it would effectively allow users of the processor to overclock their PC.

Ryzen 7 5800X3D pricing

Videocardz has reported that AMD's Ryzen 7 5800X3D will cost $449 US, which translates to around £450 when VAT is included. AMD is reportedly launching their Ryzen 7 5800X3D on April 20th.

I don't think this is in general a big issue because for most people on the mainstream, the algorithm can do a much better job of boosting and maintaining clocks based on temperature and doing a all core overclock just removes that feature, as for professional overclockers, they probably just skip this or find a workaround.Quote

They pretty much always have custom BIOS's flashed when doing their pro overclock events. So to them they don't even care.

I'm curious to know if it's a limitation on the infinity fabric with the added 3D cache. If that adds more strain or increasing the fabric speed negatively harms cache performance with their current vertical designQuote

I would imagine it is the cache itself. It's never ever been a good idea to overclock cache, as it's the most likely way you can ever kill a CPU.

I know it's not related, but look at how "well" (yes I am being sarcastic) HBM overclocks. It was terrible.

Because everything seems to be tied to the IF clock on Ryzen it could simply be that overclocking the cache would kill the CPU.

This is also going to be more of a problem the more things shrink down. And is also why Ryzen clock speeds were always a bit poo compared to Intel, and why it took Intel so damn long to shrink their CPUs *with* decent clock speeds.Quote
