ICYMI, AMD Claims to have Caught Up with Core i9-12900K Gaming Performance Even Before Zen 4
The Ryzen 3000XT line of processors were the kind of stop-gap products that make people wary of stop-gap products, and AMD plans to remedy this. The new Ryzen 7 5800X3D is an upcoming Socket AM4 processor designed with the singular purpose of matching the Intel Core i9-12900K "Alder Lake" processor at gaming performance, so Intel doesn't have free reign until much later in the year, when AMD debuts "Zen 4" and AM5. It's also a means for AMD to signal consumers as well as investors to the sheer engineering depth the company enjoys these days.
The Ryzen 7 5800X3D isn't a a 5800X with an insane CPU overclock that throws efficiency out of the window. In fact, it has lower clocks! Instead, it leverages a new feature addition AMD did to its existing "Zen 3" microarchitecture, called 3D Vertical Cache. This is basically 64 MB of fast SRAM physically stacked on top of the CPU core die (CCD), giving it 96 MB of last-level cache. The company has already debuted this with its EPYC "Milan-X" enterprise processors, and the Ryzen 7 5800X3D would be the first client-segment product with this CCD.With 3D Vertical Cache tech in place, "Zen 3" enjoys a gaming performance boost akin to a generational update, with AMD claiming anywhere between 10 to 40 percent gaming performance gains over the Ryzen 9 5900X despite four fewer cores; which helps it sneak behind the Core i9-12900K "Alder Lake-S," currently Intel's flagship desktop processor.
AMD CEO Dr Lisa Su was specific about who the 5800X3D was for—those who use their PCs for one thing only, gaming. The chip has 8 CPU cores, with SMT enabling 16 logical processors. Each of these has 512 KB of L2 cache, and share 96 MB of L3 cache. The processor ships with lower clock speeds than the 5800X, with a base frequency of 3.40 GHz (compared to 3.80 GHz of the 5800X); and boost frequency of 4.50 GHz (vs. 4.70 GHz of the 5800X). The processor's TDP is the same as the 5800X, at 105 W. As we mentioned, this isn't a case of the designers running the chip at eleventy GHz and several hundred Watts of TDP.
The 5800X3D, as a Socket AM4 part, is drop-in compatible with AMD 500-series and 400-series chipset motherboards, with a BIOS update. Since its TDP is unchanged at 105 W, it doesn't come with any special VRM requirements (at least nothing different from what the 5800X needs).
Intel has already reacted to this development, by announcing the Core i9-12900KS, a variant of the i9-12900K with a massive 5.50 GHz boost frequency for the P-cores, which it hopes will ward off the 5800X3D. Intel is missing the point here. The 5800X is a $400-something part, priced rivaling the i7-12700K, and while the pricing of the 5800X3D is unknown, it's highly likely to end up with an enormous gaming price-performance advantage over Intel. The 5800X3D releases this Spring.

If I didn’t have teens, a house and family I would throw a few grand at it to see what -28F nights would allow it to do, or some good old fashioned dry ice and alcohol.
But since the 5800X was already a OK overclocker, imagine that thing running at 5GHz.
There's never a price-performance advantage at the top end. The winner in that section will be the 12400F on B660.
But I see Zen 3D as a home run for AMD, even with Zen 4 coming out in Q3-4 this year. DDR4 is in its prime, boards and agesa updates are mature, lots of 3rd party support and guides are available, and it seems to trade blows with the 12900K in single thread which is more than I was expecting. Zen 4+ would be the upgrade from this product imo. By 2023/4, DDR5 should be more stable, faster and cheaper, PCIe 5.0 ssds will be more available and pretty much all the stuff that applies to Zen 3 right now.
Hopefully these processors can attain a higher fclk. Being able to run 4000cl14 without winning the lottery would be nice.
I wonder why they didn't do Borderlands 3, from TPUs own testing that games seems to love cash, errr cache.
Another leak showed all-core boost of 5GHz, but that may have been incorrect
Decent chance i'll get one of these, leaving my 5800x for my server or VR system...
But I agree, until a few third party legitimate people test the two new top dogs who knows who's nipped it, damn interesting time's though.
I'm torn 3Dcache good, 32 core's better in crunching aghh,. And skint ,da f#@£.
That said, I want to see a high performance 5950X3D made, if only for massive gains on their best binned parts (that aren't going into EPYC).
One good last hurrah for AM4 (58003DX and then a 59003DX later) to keep those AM4 mobo sales pumping while AM5 production ramps up...
Hell, i imagine a 56003DX with the full cache would do amazing things for gaming, with better power efficiency.
Edit: 3DX, X3D, 3DFX... i'll get it right one day.
I'll also take price in to the account when going for this & it needs to be close to zen2 in terms of perf/$ for it to make sense for me, otherwise I'll just get vanilla zen3 instead.
