thats intel binning by clock and gpu count. If AMD binned by RAM there should only be 3 SKUs.

It would also be useful to have SKUs with 1 or 2 CPU CCDs

But that's water under the bridge for Strix Halo, since the decision has already been made and there are pictures / schema of Strix Halo products with memory not part of the CPU package.

I only read at some site that the rdna 4 will have a raytracing power sightly lower than ada lovelace. From they where, is a huge jump. Could be on the stxh? Viola(ps5pro) will have it.

But they aren't doing stuff like replacing malloc libraries or using PGO, so I'd argue the results reported by Anandtech (when they had people doing that) or Geekerwan are more useful for comparison than the "official" submissions.

There isn't any effective way to standardize between say macOS and Windows, nor should there be. Pretty much every developer on macOS and iOS uses XCode, so using the latest Xcode release with some basic optimization flags that ordinary developers might use is how Apple Silicon performance should be demonstrated. It doesn't matter if it performs better or worse running Asahi Linux, that's not what 99.9% of Mac buyers are running. Likewise on Windows you'd want to use the MS C Compiler, though there are arguments for using vendor compilers since some developers may do so.

Trying to make them all equal by saying "OK we'll use gcc on everything as the lowest common denominator" might level the playing field, but the information you get doesn't really prove anything. The goal isn't "how does M4 compare against Zen 5" in some sort of abstract sense divorced from the realities of the Mac and PC platforms, the macOS and Windows APIs and development environments, etc. If Zen 5 performs better under Linux or M4 performed better using DDR5 instead of LPDDR5X that's not relevant as far as I'm concerned, because that's not how those CPUs are used (unless you are the 2% or whatever like me and actually do run Linux on your desktop)

The problem is SPEC is a pain to run, so asking people to re-run it just because there's a new compiler rev or something just isn't worth the trouble. If you want something you can run often there's Geekbench. Its just too bad it is so bad as far as benchmark repeatability, but that's going to be true of any benchmark that runs quickly in today's world where you have a bunch of cores and they can all adjust their frequencies moment to moment depending on temperature, load and the phase of the moon.
You missed the point. The problem is not the compiler used, but the compiler options used. If one person disables any useful vectorization and the other one enables everything hw can use, comparing scores between what they get is meaningless. What makes sense is comparing AT results with AT past results under the same environment and comparing let's say Huang results with the results he got in the past, but comparing AT SPEC data against Huang's tells you little.

Additional problem is the environment, if somebody claims he measures Zen5 core but in reality the environment he is using doesn't allow to enforce this then there is a problem with methodology. I mean it's fine to do system level performance tests but when you want to compare "PPC" like things then let's compare apple to apples...

So since people who so far presented SPEC results are using different environments and different compilers with different compiler options, comparing their results is more like comparing apples to oranges than apples to apples.

Did you see someone doing this?

This goes back to why Linus and I tend to mostly pay attention to the gcc subtest (or the clang test in GB6) and ignore the rest. Compiler options won't you there (other than maybe a better malloc) nor will vectorization. gcc/clang is big enough that it isn't helped much by fat caches, has enough unpredictable branches that it isn't helped much by high clock rates either. It is as close as you can get to a stand-in for "what's the performance of a PC/phone running a browser", because that likewise has too big of a footprint to be kind to big caches, but is too branchy to be kind to high clock rates either. If you see something is 2x faster in that test than something else, you can lay down your money it will feel 2x faster when you're sitting there browsing.

If you object to the idea of "how fast is my PC just running a browser" as a stand-in for your workflow because there's some particular thing that you spend most of your time doing then you probably shouldn't care about SPEC results at all, because unless you're a scientist or in math/stats the SPEC benchmarks aren't doing what you're doing when you're editing video or playing FPS games.

I completely agree from a user point of view.

But when a new CPU is developed or when passionate amateurs try to understand if a new CPU is faster, you need two things:

1. Fair comparison against previous gen or competition to see if the uarch is really improved. There you need the exact same binaries or something compiled with the same (non optimal) set of flags on the platforms with a different ISA.
2. Push the compiler options to at least get support of new instructions to get the "absolute" improvement. (This might require support from compiler teams to support new extensions.)

So basically you need at least two sets for the same benchmark. And even that is a big pain and requires a lot of work.

Note I'm not talking trying to get the top achievable score by using some exotic flags (such as what is seen in some results in SPEC results DB); this is completely unrealistic.

It seems to have become AMD's MO to announce launch date so far ahead of time to actual launch date that even a dedicated thread to speculation of the chip dies out weeks before the chip actually launches.

Classic AMD launch.

What?

The chips would be in our hands already if it weren't for whatever issue caused them to recall them. They couldn't have forecast that ahead of time.

What do you mean, what? Almost the same exact thing happened with Zen 4 launch. They had announcements about announcements about even later launches.

>+15% ST given and blender tease on June 15. August 15 announcement about livestream announcement on August 29. August 29 announcement about September 27 launch.

This thread is exhausted and the desktop chips launch is still a week away, lol.

Considering the situation at Intel, Desktop Zen5 can be postponed until winter just for fun.

Now it's best to sit back, and watch what Intel will do and just be surprised or laugh. An old example, but it still fits in well with all the current circus and problems at Intel.


- insanely fast processor, hello to the Intel 13/14 Gen that are no more insanely fast

Almost every official CPU announcement from AMD has preceded release by around 1 month. This would have been a bit different with the announcement preceding launch by 2 months, however that doesn't change my point that we would have processors in our hands right now at the very moment you decided to begin to complain if it weren't for an unforeseeable issue.

That CPU+dGPU combo is more expensive in every single way that isn't the manufacturing cost of the silicon. More complex PCB, more complex layout, more complex cooling, two different memory pools, etc.
That reply was for manufacturing cost only.
And even If we start to talk about laptop BOM, then I wouldn't be so certain about the rest being that much more complex -> more expensive.

More complex PCB and more complex layout is in my opinion about the same thing and I wouldn't be so sure about It costing significantly more.
Yeah, you have 2 packages vs 1, but Strix Halo package is a lot bigger in comparison, and you have to put 8 memory chips for 256-bit, so the same as the CPU+dGPU combo.

You don't necessarily need a more complex cooling If you stay within comparable TDP, in that case Strix Halo having only a single package would be at a disadvantage needing to cool a single place.

Strix Halo needs 8 chips of LPddR5x 8533 for 32GB(16Gbit chips). Is It really cheaper than 4 chips 32GB LPDDR5(x) + 4 chips for 8GB GDDR6?

But this debate is already flawed considering Strix Halo is a lot more performant than 8840 + RX 7600.

It still won't be cheaper, but might not be as much more expensive than you think.
And what do you think I think? Because I didn't say anything about that.

what about GPD claims?
They have to be fake. Didn't we also have Timespy Results above 4k leaked? 3.6k is the best ive seen so far on real units.

Computerbase posted their all core clocks during CB24: 3.43GHz. If we do the math we get to around 1200 points when all cores run at their boost clock. This matches the 3rd Party reviews, there's no result that much over 1200 points.

Well, better not check how many times and how far in advance Intel "previewed/presented/unveiled/talked/preannounced" Meteor Lake and Lunar Lake. I think some of those were like year in advance. I always have problem finding words to describe the nature of the announcement. Not quite launch, not even paperlaunch, but we already used "sneak peek" last time, and they didn't quite "unveil" that much so can't use that word... but you can tell it isn't announcement yet, because they said they are working on it but it will clearly launch only next year and you just know there will be more of these "not announcements" later so you would look silly if you used the word now...

Or all the Qualcomm announcements spread over 9 months prior to the Snapdragon X (actual) launch. Compared to that, Zen 5 was really kept secret for quite long and not really spammed too much.

Not that I'm criticizing it, it's merely a strategy trying to maintain public and media attention, the more events you make the more coverage. Plus investors see you have not just resigned and quietly awaiting death.

That's a made-up issue if I've ever seen one.
A made up issue? They announced an official launch date over a month ago, and here we are 4 days post original official launch date and AMD have not even officially announced pricing. Best Buy had to do it, yet its still not official. Its a bit much. And Im making it all up, apparently.

Fantastic launch, 10/10.

The complaint is an odd one. As you correctly point out, the media promo tour surrounding Zen 5 is rather subdued in comparison to many other recent products. Meteor Lake covered a lot of track.

AMD should have delayed it to Sept 1st to ensure all the bugs are ironed out. They risk getting bad reception if some of the above is true on the launch date.

For once it would be nice if they release something that would just work. No USB issues, random stutter etc. It took ages for them to fix USB issues and fTPM stutter on Zen3. Things are finally working properly (for me at least) but that should have been the case at launch.

Since you post there you should ask him why in the ST tests he removed CB R15 to replace it with CB R20 while there s already CB R23, and why he s using POVRAY 3.7 wich is known to give an unfair advantage to Intel since it doesnt enable AVX2 for AMD.

Basically his ST tests amount to use CB R23 twice + Povray, why not add 7 Zip ST since that would add an INT based test to the 3 others that are geared toward FP with the bias i mentioned..?.

Sorry, in which test is that? I can't find it.
