Intel Working on Fixing "Arrow Lake" Gaming Performance with Upcoming Patches
In an exclusive interview with Hot Hardware, Intel acknowledged that its recently launched Core Ultra 200 desktop processors, codenamed "Arrow Lake," have significant performance issues. However, Intel announced that a set of fixes are being developed. As our review confirmed, the launch of these new processors fell short of both consumer expectations and Intel's own projections, particularly in gaming performance, despite showing promise in productivity, content creation, and some AI workloads. In a discussion during a recent livestream, Intel's Robert Hallock, VP and general manager of client AI and technical marketing, addressed these concerns head-on, describing the Arrow Lake launch as "disastrous" and attributing the underwhelming performance to inadequately optimized systems.

Robert HallockI can't go into all the details yet, but we identified a series of multifactor issues at the OS level, at the BIOS level, and I will say that the performance we saw in reviews is not what we expected and not what we intended. The launch just didn't go as planned. That has been a humbling lesson for all of us, inspiring a fairly large response internally to get to the bottom of what happened and to fix it.Additionally, Hallock indicated that users can expect these updates to begin rolling out by the end of the month or shortly after that. The tech community awaits independent verification of these performance improvements, which could restore confidence in Intel's Arrow Lake platform and potentially reshape the current CPU performance hierarchy. Given that the promise is a "significant" performance uplift, we expect to see some interesting numbers as Intel's cores are performant from the microarchitectural standpoint. The mix of Windows and BIOS updates will be interesting to measure in the coming weeks. Here is the link to the video interview of the Hot Hardware crew and Robert Hallock.

They should fix everything in Arrow Lake that could possibly cause chip degradation.

More power usage to perform better and likely some adjusting the voltage to to CPU. ?
ARM tech is probably going to take over the whole thing both in PC, smartphone and tablets and so on.
A big bandage on the thread director and windows scheduler to try to 'Evade' the E-cores while in a gaming load ( White listed manually )
To me there is an issue with scheduling (which I am not confident will be fixed by Intel), and the memory latency issue.
The windows scheduler which me and some others ramble about, is far from optimised. Some people still think a 2nd logical core is faster than a real e-core, this simply isnt the case. But the windows scheduler is somewhat stupid, I expect it still schedules on these chips like it expects the HT core to be there, I have observed it on my RL chip when I disable HT core scheduling. Instead of putting the extra thread on a different core, it just puts the extra thread on the same core instead of the 2nd HT core when HT scheduling is disabled, its dumb.
This problem however is mitigated by some manual tuning in the power scheduler settings, the heterogeneous policy 4 (windows 10 default) as an example behaves better than policy 0 (windows 11 default). I also think policy 1 is better than both 0 and 4. The rest of fixing it can be done with something like system informer or process lasso.
A big problem that Windows scheduler has, and I wonder if this will be part of the Intel fix, is if p cores are set as priority for foreground, the scheduler does not like to push extra threads on to e cores, this is pretty dumb, again it seems designed to assume HT is the way.
Intel are to blame for these issues, the same way I said AMD's issues they hold the blame for, to be fair to the Intel rep, he was pushed to blame Microsoft, but he said its all on Intel.
Productivity apps usually use e-cores and p-cores side by side ok, although certain scheduler settings will break this as well.
Also whilst some (a minor amount) of games will use up to 14 threads on consoles, its still much more common to be 7 or less.
AMD's loss.
Probably the worst CPUs since Pentium 4. Not probably, for sure.
Nothing can patch cache speeds I believe. But let them cook...
Look, I'm not fond of Intel - they've always been the incumbent giant who stamp out competition with shady and illegal practices - but there's no denying that Arrow lake is objectively a decent processor, even if it's neither the best application CPU nor the best gaming CPU - it certainly does a reasonable job of both. On top of the objectively decent performance, the reduction in power consumption compared to 13th/14th gen is good news for everyone. Yes, they're still hotter than, and less efficient than Ryzens of any flavour, but they're more power-efficient than their predecessors which is progress we should be happy about.
It would have been much better to cap off mainstream platforms at 100W, and keep the proper HEDT segment in all its glory, with a good selection of affordable and flexible motherboards, lots of IO, 4 memory channels and "standard cooler" compatibility. With the popularity of NVMe drives, more PCIe lanes are more important than ever.
Threadripper and Xeon W platforms do exist, but in very limited availability and very high entry (Threadripper), needing special coolers, usually no store stock, and have been lagging behind their mainstream counterparts in getting to the market. (They are rock solid though, for those concerned about long-term stability.)
And back to what you said about Ryzen bringing more cores to the mainstream; Intel had originally scheduled the cancelled Cannon Lake (10nm shrink of Kaby Lake) with 8 cores to launch around the same time as Zen 1, quickly to be followed by Ice Lake (again 8 cores) the following year. While we all know about their 10nm disaster, it is important for historical accuracy to point out that it was node limitations preventing them from adding more cores earlier. The second half of the sentence in my post that you cut explains it; if the BIOS incorrectly detects/configures hardware, it can certainly affect performance. But this would be a bugfix of something reference implementations did correctly during qualification testing, so such fixes are not an optimization what will change how the hardware behaves.
For 4K some games may benefit from a strong CPU: Flight simulator 2024 and Monster Hunter Wilds (RE Engine is cpu intensive), civ vii or stellaris just for reducing loading time for each turns but that's far less important.
Other than that yes at 4K you are in general GPU limited.
