To be fair ARM got a LOT better between the time they announced the Nuvia acquisition and time the first fruit of that was released a year ago.
Good point
That "crowding" between Apple, Qualcomm and ARM might be because they've all mostly exploited the same ideas.
Something interesting, Apple and ARM seem to be going high IPC and lower clocks vs Qcomm going higher clocks and relatively lower IPC... but then Apple and Qualcomm use the same general caching setup (and interestingly enough, Tenstorrent too) while ARM uses the more traditional one.
Apple seems to have the best of both worlds lol.

This is the laptop part, yeah? We don't know that the clock rate is accurate. But it being roughly correct is a very simple explanation to the low results in e.g. ... all the non-SME subtests.

What's even less reliable than GB is wherever the 4.7GHz comes from. Even if that rumor originated with Qualcomm they missed last time..

Lowkey if I was Qcomm and my expensive cpu team acquisition can't differentiate themselves well from the stock ARM stuff, since that didn't really happen this gen with the x925, I would start getting mad lol.
The expensive team failing to deliver is the easy answer, but not a complete certainty. The new team still had to integrate in a complex organization, and that cost (in time, stress, politics etc) may reflect on the Geekbench sheet more than we'd like.

I don't understand why they're pushing so high with clocks, though I guess that makes more sense if they plan to use the arch for PC devices as well. Still a recipe for disaster though, my guessometer would argue high speed designs fail more often than they deliver.

4.74 is the figure reported by CPU itself.

We still don't know what that "4050" clock rate means, and whether that's accurate since we've all seen GB6 produce wildly wrong frequency numbers on unreleased parts. If it can run at 4.7 GHz why wasn't it tested at that speed? Or is it that it can "run" at that speed, but only in one of those ridiculous phones that has a fan in it? I don't buy the "its an engineering sample" argument. Its not far from release and it is on N3P which is effectively a mature process from day one - TSMC never has yield issues with their iterations. So if it can only run at 4 GHz they can't blame the process on that, it would indicate some shortcomings in design.
Very true, GB6 clock readings are wildly inconsistent. Given that the predecesessor already pulls considerable amount of power @ 4.37, I wouldn't be surprised if 4.7 is only achievable in actively cooled devices (or in a fridge lmao)

Here's a laptop I ignored for a year because I blamed LPDDR4 for its high latency: https://forums.anandtech.com/threads/post-your-maxxmem²-score.2608515/post-41492029

Here's the Geekbench 6.2 comparison before and after fixing the laptop's performance by nuking power saving settings in the BIOS: https://browser.geekbench.com/v6/cpu/compare/13297047?baseline=5554294

I feel sorry for the suckers living with the OOB lame performance of this laptop. It may have even contributed to the sales failure of this model. If only the engineers had provided a turbo button on the laptop to provide boosted performance on AC power instead of forcing the user to figure out how to unlock the dormant performance...

Notice the tests that loved the latency being halved:

Here’s a good benchmark for memory latency etc, been playing with it. Will share my results soon.


If you want to run on Linux do not use the complied version. Compile it your self cause the complied version is using python 3.7 and messes up and gives a lib shared error.

macOS is easy too just follow the steps listed in the readme file.

For the windows version, I recommend running it from Benchmate.

Why desktop Zen 5 still sucks: https://browser.geekbench.com/v6/cpu/compare/13362867?baseline=13181601

1755569392118.png

In a sane world, a product using the same architecture with a deficit of 8 whole threads should never be getting this close, let alone beating the higher thread product. Possible reasons are lower RAM speeds, crappy IOD and cross CCD latency bogging down the supposedly better product.

Found a 9900X DDR5-8000 result that manages not to embarrass itself: https://browser.geekbench.com/v6/cpu/compare/13025710?baseline=13181601

OK, comparing now with the Ryzen 390 so the 9900X can stop feeling good about having more threads: https://browser.geekbench.com/v6/cpu/compare/13025710?baseline=12463079

The desktop CPU loses in two MT subtests:

That ASUS laptop has DDR4-3200: https://valid.x86.fr/2vxtte

The Acer one has DDR5: https://www.acer.com/us-en/laptops/aspire/aspire-go-intel/pdp/NX.J73AA.001#pdpSpecs

So a pretty good comparison highlighting the tests that are latency sensitive and how JEDEC screwed people over with DDR5-4800.

Bravo!

I hope everyone who signed off on the DDR5-4800 spec suffers from something lifelong because they did this on purpose and their complicity in this heinous act of deception has affected the performance of millions of CPUs.

You sure theyre using the same power limits? Does the clockspeed url show they were running the same clocks or was the asus at an advantage in the test?

Haven't checked that. The Acer one is acing the bandwidth sensitive MT tests though. Wouldn't be able to do that with lower power limits I think.

Huh? DDR5 4800 JEDEC does have more bandwidth than DDR4 3200 JEDEC, so I am unsure what your initial complaint is if the DDR5 one is doing better on the bandwidth sensitive tests?

Alder Lake-N is very memBW bound due to having a single 64 bit channel. The N100 woth only 4 cores is already struggling, doubling it to 8 cores in the N305/N355 is murder. Of course it could do better even with less power at lower clocks due to how constrained the platform is.

The answer is in the data. Ill check if I can figure out the URL later.

I was lamenting that DDR5 is more bandwidth focused at the expense of latency which hurts many workloads and allows DDR4 to pull ahead. They could at least have strived to release just the initial DDR5-4800 spec with CL36 instead of something like CL46+. Then even these bargain bin laptops could've extracted optimal performance out of their scrawny CPUs.

CL46+? The vast majority of 4800 JEDEC is CL40. CL42 is the worst bin per JEDEC.

JEDEC has different speed bins for each frequency. CL40 is not the best tier.
Not exactly sure who's at fault for no one using the best bin, but the mfg seem to be a prime candidate.

My bad. I misremembered probably coz I recall some reviews using bad Corsair CL46 RAM. But that CL34 bin was pretty sweet. Wish they had launched with that.
It feels like DDR5 barely scraped out the door and hardly worked when it first came out. I don't think launching with 4800CL34 was ever going to happen.

Why none of the DRAM MFG are targeting the better speed bins with new dies now? No idea. Maybe they think it's unnecessary because people will just buy XMP/EXPO overclocked ram, and they assume on servers it doesn't matter?
