Did you expect them to admit this? lol! Of course they did. They are working on new hardware.

From what I gather, the boost clocks are 5.7 ghz for the 3D chiplet. This is from the rumor mill, however, so we will see at launch.

That would be quite out of this world, if true. It would, theoretically, outperform 9800x3d by nearly 10%, based on clock speeds.

I am a little skeptical. I think AMD would mention it / demonstrate it.

Idle power of Strix Halo look quite good given the gigantic SoC design, HP state 5.32W for the full laptop with IPS screen.
OEM Battery life Claims are usually double of what you get in reality. So realistically we should expect 7h, which is good for the performance Tier but nothing out of this World. If Optimus and Co. work like they should it is achievable by many currently available devices.

Hmm, I was misled by a 3rd party site which for some reason lists 15 W. Right at this moment, amd.com lists 28 W default TPD for both indeed. (Edit: Snapshots of AMD's product pages at web.archive.org also say 28 W.)

That s OEM dependent, Lenovo FI did set it at 22W sustained in one of their laptops.

HP state 5.32W for the laptops and you are saying that it s actualy 10.64W, that s quite a big difference with nothing else to support your claim than a "trust me bro"...

Now show us the devices with comparable GPUs and CPU that last that long, and not with a conditional "if", real numbers from existing products and 5.32W idle power, there s scores of tested laptops at NBC and their settings are quite forgiving for battery life when idling.

I am of the opinion that KRK is NOT a full tier replacement for HPT. HPT provides 20 lanes of PCIe. KRK only provides 16 as per AMD's official page with specs. PHX2 only had 14 lanes. KRK is, at best, a generational upgrade to PHX2.

I await lab benchmark tests between HPT and KRK using largely comparable laptops set to the same TDP. I suspect that KRK will indeed be better in ST, but in multiple situations, I suspect that HPT will be better in MT, assuming they both have the same memory configuration. I also think that Radeon 780M will be broadly better than the 8CU iGPU in KRK until HPT hit's power/thermal limits that starts to throttle 780M a bit.

It's OK. You'll still be able to purchase HPT in the warmed over Ryzen AI 200 series, and HPT is still going to make for a really good laptop processor.

I personally would have been fine with a 2+6 config with the extra die space dedicated to the iGPU to make it a 12CU RDNA3.5 implementation. That would have been an improvement in the two most important parts of the user experience, ST and iGPU performance over HPT. MT might have been a wash or a slight step back in some cases, but, it also could have made for a better laptop experience in general, especially for the U series where TDP limits keep all but a couple of cores heavily throttled most of the time anyway and they are FAR more likely to be TDP limited to lower wattage ranges. It also would be better differentiation with Strix Point.

The most recent ones is basically every Lunar Lake device. Claims ar mostly in the 27-30h region while reality is 14-15h for most.

NBCs power draw and battery life numbers never line up properly. There is a ton of reviews where they measure 20W or something minimum Idle power and then get 7h battery life. Pretty sure there is no gaming laptop where they measured 5W but there's plenty over the last years with 7h or more battery life

It's probably 5.2-5.3GHz. If it's 5.7GHz then they would not having been so careful saying it's the fastest 16 core gaming CPU.
Bet it is higher. We already know those X3D parts can hit 5.6-5.7ghz without LN2. I guess we will find out soon. 😉

EDIT: AMD said the chip was 8% faster than the 9800X3D. Where do you think that gain comes from. Not the second CCD!

8% faster. Than the 7950X3D. That's Zen 5% in action combined with 150MHz effective clock increase.
Please stop hyping for a boost that isn't coming. There is nothing special about it. AMD is hiding the clock rates because that's just what they do.

GNR-31: Testing as of Nov 2024 by AMD Performance Labs using the following game titles tested at 1080p high settings: Black Myth: Wukong, Avatar: Frontiers of Pandora, Hogwarts Legacy, Call of Duty:Black Ops, Starfield, CyberPunk 2077, Counter Strike 2, Final Fantasy XIV, Hitman 3, Warhammer 20,000: Space Marine 2, Watch Dogs: Legion, Far Cry 6, Ashes of the Singularity. Both AMD Ryzen 99950X3D and Ryzen 7 7950X3D systems configured as follows: GIGABYTE X870E AORUS MASTER, 32GB DDR5-6000, Nvidia RTX 4090, KRAKEN X63, Win 11 Pro 26100, VBS ON, SAM/REBAR ON.

Your shared footnotes says "VBS ON". Of course it's gonna be higher than 8% with that abominable setting off.
Igor, come on. The point is there is no real clock rate increase beyond the 9800X3D. C.f. AMD's testing for the 9800X3D. Compared to the 7800X3D (also with VBS on) they presented the same 8% performance increase. Stop trying to manifest more clock speed, it isn't happening. It's 5.2-5.3GHz at most.

That HP G1a looks pretty sweet

Wonder what MSRP will be for 128 GB model and availability in general

What will minimum memory for Halo be? They say 128 GB with up to 96 available to GPU, I wonder why 32 GB are reserved?

Does that mean min spec will be 64 GB?

Probably to protect the OS from swap file paralysis. The 128 GB Macs have the exact same 96 GB limit, but a simple terminal command can give as much as you want to the GPU. macOS has usually been seen to be stable with the GPU taking as much as 120 GB of the RAM, though you’d want to be judicious about multitasking if you are giving the GPU nearly all the RAM.

It is almost certain that there will be ways to do the same on Strix Halo in both Windows and Linux.

the whole KRK, HWK, PHX2 stuff is completely pointless rebranding

they are all equal or worse than the original Phoenix, 7840HS

that's all there is to it


big shame there's 100 arrow lake laptop models and only 2 halo and few fire range...

what the hell is going on

Highly unlikely. The entire economic model of AMD's desktop dual CCD CPUs is to give you a good binned CCD and a lower binned reject CCD from their server CPUs. That's why the 9950X has one CCD that boosts to 5.7 and the other boosts to 5.4. The X3D chip to match their existing algorithm for the 7950X3D would then most likely just pair the 3D V-Cache with the reject/lower binned CCD that goes up 5.4, so when frequency is needed for tasks it switches to the faster CCD.

Yea I had I think it was a 800 USD Sapphire Nitro+ BUT it said shipped from Amazon.

Well, they refunded the money and told me if product arrives to keep it. (It never did). I did try following up on tracking numbers, because I got a few. Also searched the seller origin, IMO seemed like it was backdoor sales from factory workers.
I at least had the Amazon refund on my side. For this case I had no problem spending the extra 30 MSRP shipped and sold by Newegg.

This listing is just bad. ALWAYS check the Prime box at top left side. Filters out this stuff.

Anybody seen 3d chiplet clocks for 9950x3d? AMD's site just show usual "up to 5.7", without breaking down by chiplet type.
See below.

Ok according to the CES 25 presentation I watched twice, (looking for RDNA4 info)

What I did catch on the 9950x3d was that there are some options either in driver or windows, where if you need the large cache, the other CCD would be turned off. But the guy did speak about if your workload needed more single thread (I could be wrong here, it may have been up to 2 cores) then the non 3d die would be active and boost to the higher frequencies. Then if you needed as much MT performance as workload requires, then both CCDs would be on.

This was in the CES 25 livestream by the AMD guy in the black suit. (name escapes me) Lisa was not present that I seen.

This was strictly about the 9950X3D. Which if I recall was sandwiched in between the talk of AI HPDC and before Strix Halo. For sure before the Dell guy and maybe before the Lenovo guy.

Trying to pull this off memory rather than looking for and time stamping the video.

It did sound like 9950x3d would have 2 good CCDs.

Hope it helps.

EDIT: After Bob's post, It would seem the non v cache ccd will be the better one this time. IF what I remember that guy talking about is accurate.

On the 7950X3D the frequency limitation was mostly caused by thermals because cache die was between the CCD and the heat spreader. In Zen5 the cache die is below the CCD, so there is no problem in reaching higher clocks.

There is "no problem" reaching 5220MHz. There is "a problem" reaching 5355MHz, can't ship it.
