X Elite for comparison;
View attachment 110004

The Oryon CPU in 8 Elite is much better than the one in X Elite.

• Vastly better ST and MT efficiency
• Lower c2c latencies
• Presence of 'E-cores
• Stable 4.3 GHz clock speed

I think calling it 2nd gen Oryon CPU is highly justified.

How much of the improved efficiency is them using the platform power as the comparison and using a phone versus a laptop?

Even leaving room for possibly not exactly the same thing being measured, that is a lot of extra power for the crown.
Well they stuffed 8 big cores innit. Gonna burn the wattage just fine.
Android phone SoCs are closer to where laptop stuff used to be 7-ish years ago in terms of peak wattage.

Wow, they are really trying to squeeze higher fees from Qualcomm.

Another Chinese reviewer.

The main thing that caught my eye here was the power measurements in multicore (Geekbench).

8 Elite 10560 16 W
9400 9182 16.2 W
A18 Pro 8602 9.5 W

8 Elite is consuming less power than D9400, while delivering more performance.

Don't violance the licensing. simple as.
x86 wins again by doing nothing as usual.
Nah, Qualcomm will likely agree to terms set by ARM. What are they gonna do move to RISC-V or go back to ARM cores?

They spent $1.4B on NUVIA, they have to get new a license. They will do so kicking and crying.

So if ARM cancels the license that would mean next year, QC would have to release CPUs based on ARM? That is embarrassing after hyping up their custom cores.

If I know Amon he won't go back or he will be pressured by the board/shareholders to bow to ARM's requirements to get that custom license back. How's RISC-V for HPC use these days?

ARM can't stop them. All they can do is stop providing validation support and ask some court to stop Qualcomm. I heard they already did both many months ago...

yeah they do, core licensing is more $$$ than the ISA one.
That isn’t necessarily a disagreement. You mean if settlement forced 10 percent more than than core licensing and for whatever reasons Qualcomm grudgingly agreed, Arm would still balk because it’s Oryon?

Otherwise, you are saying what I am saying, they want more money, whatever the core.

Looks like Phoenix-M is cut 1/2 across the board.

Seems like the GPU is better in games than benchmarks. Single threaded CPU efficiency is just on par with the X925...

“This is more of the same from ARM – more unfounded threats designed to strongarm a longtime partner, interfere with our performance-leading CPUs, and increase royalty rates regardless of the broad rights under our architecture license. With a trial fast approaching in December, Arm’s desperate ploy appears to be an attempt to disrupt the legal process, and its claim for termination is completely baseless. We are confident that Qualcomm’s rights under its agreement with Arm will be affirmed. Arm’s anticompetitive conduct will not be tolerated.”

The register file sizes and ROB resources for Oryon-L are very similar to M3 P. Oryon-M has a much larger ROB than M4 e core and interestingly has a different balance than Apple’s small core. Oryon-M has a larger integer register file and one more pipeline. For floating point, M4 e has both a larger register file and one more pipeline.

Apple-Qualcomm are much more similar than AMD-Intel, but of course they have the same father.

Geekerwan's full video on 8 Elite has been posted to YouTube:


The perf / W 1T curves of 8 Elite vs D9400 are surprisingly close, even with Qualcomm's much higher frequency and slight overall 1T perf win.

SPECint2017:


SPECfp2017:



//

Then to GB6 nT, 8 Elite is another world of perf / W, matching the D9400's 18.5W at a mere ~10.5W, and with fewer core (thank you for the tip, @jdubs03). Some can be improved uncore / fabric which GB6 nT also stresses, but whatever it is, it's is a great win.

I don't see that happening. The 60 day notice is going to force the issue - if the judge in the case (which will be heard in December, dunno when but with the holidays probably safe to assume it starts in less than 60 days) believes it is likely Qualcomm is more likely than not to win on the merits they will order a temporary stay preventing ARM from cancelling the license until the matter is decided in court.

If judge does not believe Qualcomm is likely to win on the merits there will be no stay issued. In that case the threat of having the license cancelled costing them billions in SoC sales (using an ARM designed core is a H2 2026 project at best unless they designed and taped it out already as a backup plan) will push them to settle with ARM - giving in to exactly what ARM says needs to happen. Not sure exactly what it is ARM wants, but "more money" is ALWAYS a solution to this type of dispute.

Whether that pushes Qualcomm as far as looking seriously at RISC-V is unlikely. They could probably make that work on Android via their market power, given a few years advance notice for developers to be ready. But it would end Qualcomm's dream of being a player on Windows, and I don't think they would want to give up on that dream. So I think they would grudgingly accept ARM's terms but make a big stink about it and try to play up a sob story of themselves as a victim ala Epic Games.
