we're talking mobile chips yet you shoehorn some overclocked garbage none of them will ever run.
Like at least try to cope properly.
The rate at which you're going, Zen 5 IPC might as well depend on the a multitude of likely factors - ranging from who is likely to be the next POTUS, what happens to crude oil prices due to the middle-east situation, whether an earthquake strikes Taiwan on the day of Computex, if something more objectionable than pictures of bikini models is found with Taiwanese workers in TSMC's campus in Arizona etc.

If you're trying to entertain me before the launch at least do it properly.
This is the lowest of lows, you're trying to compare mobile RVPs you know nothing about against an overclocked DT part.

I would like to note that the lower IPC score has 8GB of ram. Probably this means that the memory interface is not fully populated. I have no idea how this impacts geekbench scores.

Perhaps @adroc_thurston was actually sandbagging Z5 improvement🤣
So the first number is IPC, second is clocks, and third is IPC x Clocks. This puts Z5 at 15% ahead of Lion Cove in ST, which is decent but I was hoping for a bigger smack down, like closer to 20%, due to the rumors of ARL being 10% faster than RPL and Z5 being 30% faster than Z4.

Will need to see a composite of various benchmarks to know for sure.

It doesn't make a difference, I get same ST score with one stick and two sticks (MT score was me doing something when I see ST tests done)
I will fire up Xen or QEMU if GB can really detect properly cpu frequency properly, which I doubt but would verify if I have time.
But maybe not worthwhile since it is just an ES, stepping 0 at that, and probably microcode would be restrictive for outside distribution

Well, the geekbench browser is full of hvm results that all seem to detect frequencies correctly, so it should.

Doesn't mean it did it for an early engineering sample though

In this data there is like a double digit IPC difference between ZEN4 Mobile (1.28) , ZEN4 Desktop(1.36) and ZEN4 X3D (1.45). So the data seems to be completely wrong overall. Probably just took some random result of everything and compared it.

In which direction? As you mentioned, IPC does not scale linearly with clocks so one can argue the Z5 projections are higher than they should be.

Geekbench seems to favor Intel compared to SPEC results. You also need some sort of control over the testing as GB scores vary wildly in the browser so without some kind of control, you can get wildly different results for each CPU in question.

I did it, lscpu shows 2.6 Base for my 7950X, but cpufreq reports 2G, I don't have GB account, so maybe someone can check the frequencies
My RAM is 6000MT/s

*snip*

Comparing this now to the 2 scores from earlier (ignoring comparisons to Intel CPUs for now since GB seems to favor them), you get:

Zen 5 = 90% higher integer PPC than Zen 4 if 1.4 GHz results are true. (Edit: and 83% in FPU)
or
Zen 5 = 16% higher integer PPC than Zen 4 if 2 GHz results are true (Edit: and 51% in FPU).

Top one seems unbelievably high and bottom one seems more believable but also too low given the breadth and magnitude of changes in the design.

Both are ES samples of unknown origin so I will now go back to waiting on more official numbers, lol.

That's a very good point. Good catch.

Will Strix Point iGPU be able match/exceed RTX 3050 mobile?

This might be a hot-take. In my opinion, a 128 bit APU should be able to match atleast a 2 generation old RTX xx50 dGPU.
3050 6 GB scores around 4800 graphics score in Time Spy.

Strix Point iGPU should score around 4000 pts, so not quite there, yet.

If Strix Point would have that 16 MB IC as was rumored before by some individuals - it would touch 5000 pts.
