As you scale up TDP you incur significant cooling consequences. If they can bank on laptop users that raise their TDP settings also. utilizing AC power then why not? Extreme powersavings on the go while offering more powerful performance on the docking station. Modern laptops should be powerful when hooked up to AC power, because most users spend significant time at the office with them.

OT - I just wish modern docking stations doubled as KVMs where I could leave a desktop in the office and while in the office seemlessly swap between desktop and laptop machines. Sometimes I pop into the office on off days without laptop in hand. Hate using machines other people touch because they tend to be messy. Admin won't swing for a second set of monitors but are fine with supplying a tower at the same time issueing laptops and surface pros. Laptop screens simply suck as that second desktop when I want the function of the dual monitors.

Hyperbole much?

Besides that, if it releases on the 28th, that would mean a Sunday launch. That seems unlikely. When was the last time AMD or Intel launched a product on a Sunday?
Maybe there's some kind of misunderstanding or miscommunication. Best Buy still has most models listed as delivery on July 15, but some models were always listed as July 28.

For the Zen5 9000 series Desktop CPUs:

”Meanwhile, AMD confirms that the CPUs will launch in July and retail listings have pointed out a 31st July retail launch which is very close so we can expect the review spree to begin a few days before that.”

Has this been mentioned previously in the thread already? I don’t remember it, but I may have missed it since the thread is moving really fast sometimes.

To save everyone a click:

RAM speeds are supported at 6400 MT/s at 1:1.
Can go to 9000 MT/s at 1:2 with 2 DIMMs, 8000 MT/s should be doable for most mobos with 4 DIMMs.

PBO is turned off by default, so power is not pushed out of the box. If you turn on PBO (auto-overclocking), the power will be pushed and the processor will try to clock as high as it can within power and temperature limits (95C or whatever it is).

Regarding Cinebench:
AMD's Ryzen 9000 "Zen 5" CPUs by default will run cooler than Ryzen 7000 "Zen 4" CPUs. Based on testing with a Ryzen 9 9950X CPU (Default ES), the chip consumed up to 190W of power whereas the Ryzen 9 7950X consumes around 220-ish Watts of power in the same workloads. The workload being performed here is Cinebench R23 and we got some interesting numbers here too. The 9950X is almost as fast as the Core i9-14900KS by default and that chip can consume over 300W of power with its extreme profile.
CB23 from AT's review of the 14900KS for reference:

If we assume the 9950X (Engineering Sample) can do 41000 points in CB23 MT at 190W while the 7950X does 39300 points at 220W, that's a 24% improvement in perf/W in this particular workload.

Interesting details revealed there.

14900KS 12% faster than 7950X in CBR23 MT.

9950X is almost as fast as 14900KS (I guess that would be MT too).

With PBO, 9950X may "easily" (WTFtech words) sail past the 14900KS.

So this would mean that Zen 5 could be slower than Arrow Lake in CBR23 MT if Arrow Lake is 10% faster than 14900KS.

Seems like Intel has a great opportunity here to score a win, if they don't mess up Arrow Lake.

This matches what HUB said in a podcast when he had access to a 9950X system running cinebench.

The timestamp is 10:15 into the video.

From N5 to N4P there s 28.2% perf/watt improvement, so the 9950X should score around 46k in R23, 17% better IPC and 2-3% higher MT clock because the IPC improvement doesnt exhaust the process perf/watt improvement, so there s a tiny room left for a frequency uplift.

Also using Strix point as basis for 1525 pts in CB 2024 at 54W this mean that a 16C would do 2020 pts at 72W and 2800 pts at about 200W, wich amount to 47.5k in CB R23.

Yes, when he asked AMD about it, they removed the demo systems and later told him that the samples in the system were pre-production and were not representative of retail performance. So, assuming there is any validity to the WCCFtech story, the ES the user had could be the same issue and retail performance will be higher. That, or AMD completely lied and are trying to cover up their huge flop, lol. I think the first option is much more likely.

I suppose we'll find out soon since we're a month away from launch. I personally think this is just a preview of what to expect but I'd be happy to be wrong.

With how Lunar is performing in Cinebench R23 MT around 10200 on an ES at PL2 30 watts, also without HT. Arrow Lake will have faster and more P cores and 16 skymont cores. Perf/w should also improve massively because of the N3B. This will be a close match between Zen5 and LNC/Skymont client desktop.

As i see it, 7950x at 37k~39k is "almost as fast as 14900k" at 41k.
So 9950x pretty much matching 14900k or beating it by say another 2K with PBO on, is not that interesting. Something closing on 50k would have been.

Yeah, it's not a game changer like we all thought it was going to be, unfortunately. Zen 5 launching at the MSRP prices of Zen 4 is the highest they should ask for, imo, but given how cheap Zen 4 is, Zen 4 may still be the way to go. Ultimately, we should wait for official reviews before reassessing the competitive landscape.
