With the right DataProvider, it goes WAY higher.

Yep that is exactly in line with the expected drop from lowering the max boost, about the same as a 300W 12900K just with a way higher multicore

Holy hell.

I've started tightening my memory timing. It does increase a bit of everything.

Still have a full day or two of tweaks and I should be pretty much set!

I think the time has come to switch to DDR5.

Agreed. But 64GB of DDR5 ain't cheap.
EDIT: I will check on Black Friday for a great 4400Mhz kit. With tight timing, it can do the trick.

The 13900 is 24 cores?

AppleSi Ultra is 20, which gives the 13th gen a 20% advantage in core count.

13900 multicore pushes 28000 against 24000 for the Ultra, which is 17% compute advantage over Ultra. (It's all in the extra cores)

But Ultra lives in restricted power envelop at modest clock rates to fit inside a compact case. 13900 is flat-out overclocked with unlimited power/thermals, and will typically be paired with a monstrous GPU adding half again more power.

Last time I ruminated over the numbers, if AppleSi Ultra were clocked at same degree as as Intel it would push GB5 2500 / 37000.

Is there a takeaway? Idk... Different animals, different zoos.

But within one exhibit, when comparing 13900K to 11900K purchased just 18 mos ago, it's such a big step on multicore to make 11900 buyers feel stupid :$ Like gaslighting.

11900K -> 13900K
8 core -> 24 core
GB5: 1850 / 11500 -> 2250 / 27500
20% / 240% (it's all in the cores!)

Thank goodness Apple was back there pushing towards this E-core thing?

I did a little homework on AppleSi M1 GPU, to size up against PC.

I used TechPowerup GPU DB and counted FP32 TFLOPS:

M1 (Macbook) 2 TFLOPS => RX 560
M1 Max 10 TFLOPS => RX 6600 XT
M1 Ultra 20 TFLOPS => RX 6800 XT

>>> Nvidia 4090 80 TFLOPS!

What speed DDR5 do you have? I just ordered some 6200MHz for my Z790 Aero g. Parts are still on their way. Stay tuned for benchmarks.

TFLOPs are not the best metric for comparison since it doesnt account for driver/OS state. Geekbench 5 Metal score for 6900XT is 175k or so, for M1 Ultra it is around 100k. Even a 6800 non XT gets 120k, the M1 Ultra GPU has scaling issues presumably due to the link between the dies.

Hopefully the 3nm version in the new M2 chips coming next year will fix this, as the performance between the 48/64 core GPU is negligible compared to the price difference. I was tempted by the M1 Ultra but this issue put me off.

I got some junk DDR5 64GB 5200 CL40, and I get ~26k in GB5, was a noticeable increase in OS responsiveness with it over my old garbage 64GB 3200 DDR4 CL16 which scored around 20k. Both just running on stock XMP.
