AMD could be developing a 24-core/48-thread Ryzen 9 7950X CPU w/ a TDP of 170 W & up to 5.4GHz CPU clocks (Updated)

[BiG StroOnZ]

Summary

AMD's next-gen Zen 4-based Ryzen 7000 series CPUs could have flagship 24-core, 48-thread monster at 5.4GHz with Ryzen 9 7950X. A Chinese seller on Weibo has revealed the spec sheet of the Ryzen 7000 series, which includes a 24 core/48 thread option.

AMD's next-gen Zen 4 architecture is shaping up to be a beast; in some new leaks with a huge sprinkle of speculation from RedGamingTech and Zhongzheng Evaluation, we're told to expect AMD's next-gen Zen 4-powered "Raphael" CPUs to be led by the Ryzen 9 7950X processor with 24 cores and 48 threads with boosts of up to 5.4GHz.

 

No evidence of such a model has been found in any roadmap, but it's plausible that AMD is planning an emergency top-of-the-line CPU if Raptor Lake proves to be too good. It's worth noting that Intel intends to double the number of efficiency cores (8P + 16E = 24) in its 13th generation CPUs, which could surpass Zen 4 in content creation workloads where they're utilized. 

• AMD Ryzen 9 7950X: 24C/48T (possibly 16C/32T) at up to 5.4GHz, 105-170W TDP, ~$900
• AMD Ryzen 9 7900X: 16C/32T (possibly 12C/24T) at up to 5.3GHz, 105-170W TDP, ~$650
• AMD Ryzen 7 7800X: 8C/16T at up to 5.2GHz, 105W TDP, ~$500
• AMD Ryzen 5 7600X: 6C/12T at up to 5.1GHz, 65W TDP, ~$350

The Ryzen 9 7900X/7950X would be predicted to run at 5.2-5.6 GHz, which is somewhat faster than the 5.2-5.4 GHz expected for the octa-core Ryzen 7 7800X. A 24-core Ryzen 9 79xx would cost around $1,000 and would be released after the other versions, most likely after the higher-end Raptor Lake CPUs.

 

My thoughts

This is some very exciting news if true. Of course it's a rumor which means you should remain skeptical, as it does contradict what we have last heard from AMD. However, it does make sense considering that Raptor Lake is planning on going up to 24c. This will allow AMD to directly compete with Raptor Lake no problem. On Saturday I posted a news article regarding the possible 7800x having a 5.2GHz boost clock. It appears here that they are able to go beyond that frequency now, which means performance increases over Zen 3 are looking solid.

Update to this story:

 

Summary

A leak from the Chinese Chiphell forums suggests that AMD’s next-gen Ryzen 9 7950X CPU will feature a boost clock of over 5.4GHz. The chip was spotted running at 5.37GHz (Windows Task Manager) in a screenshot posted over at the Chiphell forums.

Greymon55, a well-known tipster has confirmed that the processor in this image is Raphael (codename for the Ryzen 7000 family), and has a peak boost clock of 5.45GHz.

 

All the Ryzen 7000 parts will boost over the 5GHz mark under load across all cores. All the Zen 4 consumer CPUs will have an all-core boost of 5GHz.

A 8p+16e config would still total 32 threads (16 perf + 16 eff), I guess AMDs SMT gains won't be that large when compared to an efficient core from intel, or that they just want to have the bigger number when it comes to total thread count.

Whatever the outcome, next Gen is definitely shaping up to be an interesting battle, especially after seeing some of these recent rumors regarding Zen 4 and what we already know about Raptor Lake.

efficient my ass, the system still run super hot and power hungry, what's the point.

Who would've guessed that competition is good, right? haha

Well, at least the efficient cores are really efficient, all of the heat is mostly due to their fat performance cores. Let's see if they'll improve in that front on the next gen.

im interested in the low end, for $350, they should bring more cores for 7600 to justify the price, since you can have more cores for the similar price with 12th gen.

[Quackers101]

double the wattage on everything! Connect with your A/C for heating your home

the AC to DC PC, playing music on your electric bill.

[TetraSky]

If it's really 24 cores, I would've hoped they'd increase the 7600's core count to 8 at least... Maybe the next gen.

But man that is quite the power consumption. I guess these big CPU/GPU companies are really just throwing more watts at their chips to get more performances instead of optimising, eh.

[RejZoR]

With so many cores I hope they'll have a better logic so the games don't just hog all the threads, do nothing on them and nerf the boost clocks with that when game could run better with fewer cores and boosting those active higher.

Next generation EPYC is supposed to be 96 cores (Zen 4c not applicable to Ryzen), known for quite some time now. If they stick to 8 CCD's then it's 12 cores per CCD and thus aligns with the Ryzen 7950X also being 24 cores (2x CCD).

 

It's actually a pretty realistic rumor.

 

I'd either say it's just coincidence about the core counts matching or realistically it's actually Intel adjusting their product to compete, because Zen 4 would have already been targeting this well before Alder Lake.

[leadeater]

@BiG StroOnZ Of course I have to also point out there are rumors next gen EPYC is 12 CCD's so still 8 cores per CCD. Will be interesting once we officially know.

 

Edit:

Also I'd point out that Zen 4c 128 cores does not divide down by 12 CCDs. So either Zen 4c is 16x 8 core CCDs or 8x 16 core CCDs.

That's mostly due to those insanely high clock speeds. Tune down the clocks to ~4.5GHz and I bet you should see sub-100W power consumption.

 

With each node improvement, both intel and amd are pushing for higher clocks speeds and more performance instead of less power consumption.

If you want a low power CPU then buy a low power CPU, they exist 

 

And I do mean from Intel, and I don't mean Atom.

170W TDP? Jesus christ, imagine the stock cooler

Good luck finding a modern T version outside of OEMs.

 

Also, I find it stupid that the only options are either "low power" (which are not as low power as previous CPUs), or either extremely power hungry.

 

There used to be a market for low power models, regular models that could be cooled and even OC'ed with a simple air cooler, and then the extremely high-end, high power consumption models for enthusiasts, but it seems that most CPUs nowadays are slowly creeping towards that last option with nothing in between.

Probably wont exist, if it follows the 5950x trend of not including once, since who'd realistically use it?

[Guest]

I see a future where AMD goes too overboard with cores to the point where Threadripper already became obsolete the second time.

 

At least they have to be streamlining their Ryzen products and extend the AM5 socket lifespan even further... Please not another Threadripper socket.

 

All I could imagine is a future in which AMD will make a 64-core Ryzen on an AM6 socket like it was yesterday, in an attempt to compete against professional ARM processors (if they ever catch on, and I think ARM will catch on.)

[Ydfhlx]

Truth is that very few people care about low power usage. That's because most generally want the most performance a chip can deliver - if one chip is 10% faster at same price it will sell better even if it uses twice the power - see 12900KS vs 5950X. In other words, I consider these chips to be kinda factory OC.

 

Also, that 170W is likely while using 24 cores. It's not really a lot IMO considering Intel's been pushing out 8-core CPUs with 125W theoretical TDP, and considering 12900K too, which has 8 performance cores but pulls well over 200W.

 

Besides, if you care about power usage, then just underclock this chip to 4.8, where you'll loose probably less than 10% of performance, and undervolt. You'll probably get it to under 100W all core.

There will be no stock cooler with these units,

Just like how AMD does with the 5950X.

Competition is fun.

Rumours I saw were pointing towards 8 core CCDs remaining, obviously follows three of them for a 24 core AM5 configuration. 3 dies would also help spread the heat and might make it easier to cool.

3 CCD also much better for internal bandwidth, 50% increase gen on gen without any actual IF data rate increase. So probably is the most likely
