Discussion Zen 5 Speculation (EPYC Turin and Strix Point/Granite Ridge - Ryzen 9000)

[DisEnchantment]

Speculate at will

 

[yuri69]

It is interesting that Granite Ridges scores noticeably higher than Strix in ST tests per GHz. ~3400pts @ 5.7Ghz ( 596pts/Ghz) Vs ~2900pts @ 5.1Ghz ( 568pts/Ghz) -> that is ~5% IPC difference between two Zen 5 implementations.

Strix got multiple known limitations, namely:
* half max L3 per core
* half (or less?) AVX512 throughput (FP benches might care)
* heterogenous CCXes (a thread might be scheduled on the Zen5c CCX)
* energy-optimized DVFS

half (or less?) AVX512 throughput

AMD haven't publicly said anything about Strix Point's microarchitecture differing¹ from Granite Ridge's/ Turin's, have they? ... To be fair, we are still pre-launch, so it's somewhat natural that they aren't particularly talkative about details like that for the time being.

¹) WRT FP pipelines, if true. I thought that'll only happen to Strix Halo's low power cores.

AMD public statements are driven by marketing... David Huang benched Strix Point and found the AVX512 throughput being the same as Zen 4 and, at the same time, both CCXes being architecturally identical.

Well to be fair, he said he tested a pre-prod. laptop with ES CPU. Still, Strix Point seems to have power optimized Zen 5 core.

Interview regarding power management on Strix point. Maybe just a lot of PR talk but they seem to have done a lot of work on power optimization. Let's see if it pays off in the review samples.

@techjunkie123, review the CPU forum rules please.

Noted, thanks. Fixed original comment.

IIRC I saw a core to core latency graph that showed latency behavior implicating it's a 4 Zen5 CCX and an 8 Zen5c CCX. The latency from the Zen 5 to Zen 5c cores was very high.

That was from David Huang, with the 4+6 SKU:

AMD Zen vs Zen 2 vs Zen 3 vs Zen 4 vs Zen 5 Core Architecture: Road to Ryzen 9000 CPUs | Hardware Times

The fifth iteration of AMD’s Zen core architecture is set to launch later this month. Zen 5 marks nearly seven years of Ryzen processors, starting with the release of Zen in 2017. Since then, we’ve gotten Zen+, Zen 2, Zen 3, and Zen 4 at the heart of the Ryzen 2000, 3000, 5000, and 7000 …

Not sure if this has been posted but found these through notebookcheck

AMD Ryzen AI 9 HX 370 performs on par with Ryzen 9 7950X in Cinebench 2024

GPD has posted some benchmarks of AMD's upcoming Ryzen AI 9 HX 370 CPU. It manages to trade blows with high-end desktop chips in Cinenbench 2024's single-core benchmark. Similarly, its Radeon 890M iGPU outperforms Nvidia's GeForce RTX 2050 in 3DMark Time Spy.

The dutch Amazon had the 9600X, 9700X and 9900X online for a small amount of time. The page for the 9900X was linked on WTFTech and is still available but missing the price. I still have a screenshot of the page for the 9700X, the page was gone when reloading. Anyway, there are EUR prices incl. VAT (USD prices excl. VAT in parentheses):

• 9600X: €307.35 (276.65 USD) (not absolutely sure if this was the price)
• 9700X: €405.69 (365.12 USD)
• 9900X: €508.49 (457.64 USD)

The 9950X wasn't listed.

I find these interesting because they were actually below launch MSRP of Zen4, for example around 90 USD lower for the 9900X.

This is the one to look out for. Gobs of bandwidth available to the CPU and GPU and unified memory of up to 128/256GB(?)

One can wonder if this will be a problem in newer games that might use more than 4 cores. I mean according to AMD X3D get only one V-cache die, as cross CCD latency would be prohibitive, and here we have cross CCX latency that doesn't look too good. Could it be that Hawk Point may do better in some games than Strix Point?

Because no one buys the 12 cores Zen.

AMD Ryzen 9000 processors prices listed by French retailer — European Ryzen 9 9900X price at nearly $750

Ryzen 9 9900X is priced at about a $67 premium on the Ryzen 9 7900X at the same retailer.

That doesn't sound good.

CPUs have gotten too expensive. I still remember buying the 6600K for 230€. Now a similar range CPU goes for 300-350€. That's a 40-50% increase

That shop seems to practice prohibitive prices. A much larger shop in France, which is not even competitive price wise, lists 7900x at 480 Euros vs pc21.fr 620 Euros. Amazon France is at 390 Euros.

I wouldn't deduce anything from pc21 prices.

Everything got more expensive but at least we get more performance now compared to the skylake era

 

[FlanK3r]

no problem, 9950X will be mine 102nd CPU in the colection

Still waiting for AMD to fumble the ball on Zen 5 pricing. The urge to milk early adopters has got to be very hard to resist for them coming from Zen 3 and Zen 4. Maybe they've finally learned their lesson. 9 days left to find out.

AMD's client profitability is very crappy, considering how much better their products are than Intel's. They gotta do something. I'd expect at least Zen 4's original MSRP.

If we forget about other markets for a second, Ian Cutress did a BOM analysis for the 7950X when it released in 2022, estimating total BOM to be around $70. For a $700 MSRP product. I have no idea how a 90% profit margin could be considered "very crappy profitability".

Based on his breakdown, the single CCD chips would be ~$45-50 BOM at the time.
