Phoronix: AMD Ryzen 9 9950X & Ryzen 9 9900X Deliver Excellent Linux Performance

Last Wednesday was the review embargo for the Ryzen 5 9600X and Ryzen 7 9700X Zen 5 desktop processors that proved to be very exciting for Linux workloads from developers to creators to AVX-512 embracing AI and HPC workloads. Today the review embargo lifts on the Ryzen 9 9900X and Ryzen 9 9950X and as expected given the prior 6-core/8-core tests: these new chips are wild! The Ryzen 9 9900X and Ryzen 9 9950X are fabulous processors for those engaging in heavy real-world Linux workloads with excellent performance uplift and stunning power efficiency.

When taking the geometric mean of all the raw performance results, the Ryzen 9 9950X came out to being 19.6% faster than the Ryzen 9 7950X.

126.34 / 107.25 = 1.178, i.e. 17.8%.

Looks impressive. How massive will the difference between these benchmarks and the more Windows/gaming focused crowd be this week?

Congratulations to AMD. This is the kind of innovation we are looking for.

Also, thank you AMD for treating Linux as first-class in the recent years.

It looks like Zen 5 has been optimized almost entirely for enterprise workloads.

Desktop performance improvements are mediocre and unimpressive, if not downright poor.

In gaming 9950X (RTX 4090 at 1080p) is on average just 1% faster than 7950X.

And as if it's not enough AMD has done this:

AMD needs to release Zen 5+ ASAP.

How do I read the hardware table? I can't tell where one memory stick ends and the next begins for example.

Anandtech summarizes a botched release:

Based on what we know about the Zen 5 architecture, as well as the Granite Ridge chip overall, the reasonable guess here is that we’re seeing AMD’s uncore – the memory controllers and attached Infinity Fabric – stretched to its limit. Since AMD reused the original Ryzen 7000 IOD for Ryzen 9000, the only additional resources available to feed the CPU cores is the slightly higher bandwidth of DDR5-5600 memory. All other cache and interconnect bottlenecks remain.

Consequently, when floating point performance in a single thread improves by a hefty 24%, that’s 24% more traffic through the caches and uncore/IOD to keep those CPU cores fed. And those resources aren’t quite there. To be sure, 9950X doesn’t hit a scaling wall here, as multi-threaded floating point performance is still ahead of the 7950X by 19% overall. But it’s just a bit worse – and enough so that we can measure it. I can only surmise that Zen 5 would have gladly taken more memory bandwidth and IF bandwidth if those were available. Thankfully for AMD, Rate results don’t rely on inter-thread communication, so there aren’t any hazards from threads from different CCDs talking to each other over the IF links.[/quote

Anandtech tests the platforms at JEDEC 5600 CL46. A 6000CL30 kit easily balances the core improvements to the IF/Memory speeds

How can you call it botched? They reused the IO die from the last generation. It was a tock release not a tick release. Intel.spent nearly 15 years releasing every other product generation in this same fashion.

EDIT: The thing that happened why you consider it botched is that they reused the last gens IO die... So does that mean you also think the last gen is botched too??? And do you consider every Intel release for a nearly 15 year period or so also botched???

Owner of 5950x who is dying to upgrade to 9950x, the power efficiency looks great.

I'm waiting for the X3D, hopefully as it'll really help database performance for a workstation.
