The AMD Ryzen 9 9950X and Ryzen 9 9900X Review: Flagship Zen 5 Soars and Stalls

AMD has launched its Ryzen 9 9950X and Ryzen 9 9900X processors, which are part of the new Ryzen 9000 series utilizing the Zen 5 microarchitecture. The Ryzen 9 9950X features 16 cores and a boost clock of up to 5.7 GHz, while the Ryzen 9 9900X has 12 cores with a maximum boost of 5.6 GHz. Both processors maintain compatibility with existing AM5 motherboards, although new X870E/X870 motherboards will not be available until September. The Ryzen 9 9950X has a thermal design power (TDP) of 170 W, while the 9900X has a lower TDP of 120 W. AMD has also reintroduced the PPM Provisioning driver for these models, which optimizes performance by managing core usage during gaming to reduce latency issues associated with multi-CCD configurations. This driver aims to consolidate gaming demands within a single cache domain, enhancing performance by preventing threads from straddling multiple CCDs. The Ryzen 9000 series is positioned to compete effectively against Intel's 14th Gen Core series, with performance benchmarks expected to highlight their capabilities in productivity, gaming, and AI tasks.

It’s a rather unfortunate launch. It’s showing itself at the top of synthetic multi thread and single thread benchmarks and then failing to beat the 7000 series (even non x3d variants) in games seemingly due to thread scheduling going across ccds.

I suspect it’s a hiccup and easily fixed with a software update but unfortunate since the launch benchmarks tend to be the ones that stick around.

These guys have almost no idea what they are talking about, right? JetStream 2.1 is "Java-based"? Phoronix coverage seems more relevant https://www.phoronix.com/review/amd-ryzen-9950x-9900x

Games are not one of my PC use cases so I am pleased to see that the 9950X is the new king of the hill for compiling software. My 14900K is glitching out so I need to replace it and the 9950X is a lot cheaper than a Threadripper or Xeon-W.

I guess I'm not fully understanding their Zen4 vs Zen5 conclusion. I get that if you've already got a Zen4 machine you may not feel it is worth it to upgrade to Zen5. But if you've got some 5+ year old machine and need a new one, they aren't really saying that you might want to get a Zen4 instead of Zen5, are they?

I'm soon to be building an updated gaming PC (while ship of theseus'ing parts like my 3090, SSDs, etc), and it looks like this Zen 5 series is...not it. My sights are likely set on the 7900X3D as the processor I'm picking.

> Specifically relating to the Ryzen 9 9950X and the Ryzen 9 9900X, AMD has brought back their PPM Provisioning driver.

Very interesting this driver is needed.

Has there ever been a time in the past where a driver is needed just so the CPU properly functions?

I have 5950X. Looks like I am going to skip this gen too. Kind of looks meh.
