Speculate at will

7ish hours until this, I hope slides get released online soonish.
Very curious about what claims they have about the CCX power vs Zen 4, V/F curve, and CaC numbers they have about Zen 5. I don't think AMD has yet to release a gen since zen where even at low power their next gen core hasn't had a perf/watt increase vs their past gen, but this doesn't seem to be the case with Zen 5.

where's this? how to check for slides?

btw re:9800x3d exploding (lmao)

gamersnexus published this 1 month ago




and there's evidence of shills spreading FUD of "exploding AMD chips!!!" (lmao) on reddit


then 1 week ago in light of brand new highly anticipated nVidia 5900 meltdowns, suddenly there's several new reddit posts claiming dead/burned 9800x3d, out of nowhere, all at once

#1 market cap company in the world is no joke after all

gamersnexus shows up and offers full retail price to buy the burned cpu/mobo and test them out

the claimants more or less disappeared and the topic died down

reddit is ideal grounds to create and spread FUD

Intel, Nvidia, same beasts....

Review is live:

AMD Ryzen AI Max+ 395 Analysis - Strix Halo to rival Apple M4 Pro/Max with 16 Zen 5 cores and iGPU on par with RTX 4070 Laptop

The new Ryzen AI Max+ 395 is AMD's latest high-end mobile processor. With up to 16 Zen 5 cores, a powerful Radeon GPU, fast NPU and up to 128 GB RAM, the Ryzen AI Max+ is supposed to be the ideal companion for gaming, content creation, and AI development.

Halo is a beast

 

[fastandfurious6]

Strix Halo in 1.2kg tablet



33db is dead-quiet and 45db is refrigerator hum

Halo @ 70w = 7945HX3D @ 115w

temps on full load are pegged at 70c, total ~65w + ~65w

CP2077 QHD Ultra is super demanding, fps shown are without FSR + FG, with those it's 100+fps on perf mode

we have a winner

 

[StinkyPinky]

Wow, that is crazy. Finally some good news.

Review: Asus’ ROG Flow Z13 tablet takes the asterisk off integrated GPUs

Performance like an RTX 4060, but it’s packed into a slightly heavy Surface-like.

where's this?

In San Francisco.

 

[Geddagod]

In San Francisco.

slides usually get uploaded to IEEE xplore, just don't remember when (after the entire conference?, a bit later?).

 

[511]

NGL N2 and 18A is the most exciting presentation in this ISSCC

 

[StefanR5R]

From the Zen 6 speculation thread:

According to this Tweet, the CCD in Strix Halo is indeed 66 mm2.
And according to measurements, Granite Ridge CCD is 70 mm2.

Now, is Strix Halo's CCD different from Turin's CCD too?

So, perhaps, AMD really made a bespoke CCD for Strix Halo.

Looking at the die, and the short side shrunk implies GMI is gone

Not 'perhaps'. It is one.

TSV columns are gone too!

Are you going by artistically rendered "die shots" (into which I for one wouldn't read too much into), or by additional information?

 

[sl0519]

Can you see the split wattages for the CPU and GPU? Reviews looked good because they were comparing Halo products to older Intel and Ryzen parts, but I think ARL-H might stand a chance. Considering it's using the full-fat Zen 5 cores, I found it a bit underwhelming. Single-core efficiency isn’t any better than Strix Point, and multi-core performance is only on par with ARL-H (edit: reviews number are wrong I got misleaded). On the other hand, the iGPU is a real home run - it’s consistently matching or even beating laptop 4060/70 GPUs while consuming similar wattages for the entire chip compared to a dGPU. That’s just f___ing insane. It’s a shame it’s only using RDNA 3.5 - imagine if it had RDNA 4 or UDNA with massively improved ray tracing and FSR 4. At that point, it would make mid-range NVIDIA GPUs completely obsolete.

The only CPU Worth standing a Chance is ARL-HX

Single-core performance and efficiency I meant, considering the fact that it is using the full-fat Zen 5 cores. (*edit: Dave2D got the multi-core number of U9 285H wrong so I got misleaded)

different d2d interface.

i know what it is lmao.

Fresh GB posting: 15 percent gain in single-thread for 9900 series X3D desktop over 7900 series. But pretty stagnant for multi-thread.

[Chicken76]

what are the chances the burn is falsified? is it easy to do?

Interviewer: "So tell us, how did your 9800X3D explode?"
Burnt AMD customer: "Well, I was watching my favorite daytime drama and playing with this hunk of metal that came with the computer you can see under the desk there, when the room filled with smoke"
Interviewer: "And this caused you to miss your show?"
Burnt AMD customer: "Right when it was getting to the good part too! Turns out my CPU exploded."
Interviewer: "Oh... So what are you going to do now?"
Burnt AMD customer: "I guess I'll display this on the shelf with my childhood action figures, 'cause it's pretty with the pipes and the fins you see? And replace every system I have with not-degraded-yet Raptor Lakes"
Interviewer: "Understandable. You don't feel like taking any chances anymore with these computer chips"

Damn non-representative multi-thread results. Son of a b. Makes sense though it should score right around the vanilla 9900 series.

Here are actual die shots. 2x GMI gone, and replaced with new type of connectivity:
