Oh yea. So many configs to test to find the performance / price sweet spot.Also this:
E-cores disabled or enabled?
I would have to dig through my post history (on mobile for the next few weeks, so I am not doing it now), but I believe Ii guessed $588, was I really only a dollar off? 🤣ADL-S pricing leaks?
i9 12900K - $589
i9 12900KF - $564
i7 12700K - $409
i7 12700KF - $384
i5 12600K - $289
i5 12600KF - $264
Intel 12th Gen Core "Alder Lake-S" final specifications and pricing leak ahead of launch - VideoCardz.comIntel Alder Lake will be more expensive than Rocket Lake We finally have the full specifications and pricing of the upcoming desktop series. Intel Core i9-12900K featuring 16 cores (8 Performance and 8 Efficient) and 24 threads will carry a boost clock up to 5.2 GHz, there is no Thermal...videocardz.com
The problem with cache "help" will be finding reliable information - in "stock" testing those 5-10MB extra will have outsized impact due to memory being very slow. While fully tuned DDR4 3733CL14 will lessen impact of L3.I think for many the 12400 may be the best of the bunch because that is just 6 p-cores. I am also interested in seeing HUB do their cache performance scaling testing to see how much more cache helps the 12900k vs the lower tier models that have less L3.
I would have to think they are comparing JEDEC 3200CL22 to JEDEC 4800CL40. If they used 4800CL36 (which is still JEDEC) it would only be 3% worse. 4800CL40 is 21%.Yeah, Anandtech and JEDEC timings on DDR5 will destroy them. Large L3 and L2 can carry only so much when main memory is slower than mobile CPUs from fruit vendors.
Well...That gaming perfomance looks quiet... interesting for Intel's own benchmarks. Will probably be even worse in third party reviews.
Intel did have a small one slide of comparisons against AMD in gaming with an RTX 3090, however they stated they were done without the latest L3 patch fix, and admitted that they would have preferred to show us full results.
Mit einem großen Schritt eröffnet Intel Alder Lake die Hybrid-Ära. Core i9-12900K, i7-12700K & i5-12600K machen den Anfang. Ein Überblick.www.computerbase.de
My Thread Dictator™ joke is slowly coming to life.Another factor to mention is DRM. Intel has made statements to this, but there is an issue with Denuvo as it uses part of the CPU configuration to identify systems to stop piracy. Due to the hybrid nature, Denuvo might register starting on a different core (P vs E) as a new system, and eventually lock you out of the game either temporarily or permanently. Out of the top 200 games, around 20 are affected and Intel says it still has a couple more to fix. It’s working with Denuvo for a high-level fix from their side, and with developers to fix from their end as well. Intel says it’s a bit harder with older titles, especially when there’s no development going on, or the IP is far away from its original source. A solution to this would be to only launch those games on specific cores, but look out for more updates as time marches on.
When a user is on the balanced power plan, Microsoft will move any software or window that is in focus (i.e. selected) onto the P-cores. Conversely, if you click away from one window to another, the thread for that first window will move to an E-core, and the new window now gets P-core priority. This makes perfect sense for the user that has a million windows and tabs open, and doesn’t want them taking immediate performance away.
Sounds like the first thing to do on ADL-S is to switch to Performance Plan. I'll be curious to see idle efficiency in this case.The way that this is described also means that if you use any software that’s fronted by a GUI, but spawns a background process to do the actual work, unless the background process gets focus (which it can never do in normal operation), then it will stay on the E-cores.
In my mind, this is a bad oversight. I was told that this is explicitly Microsoft’s choice on how to do things.
Nov 4th. And yes, it looks bad to me. NOBODY is saying its efficient. The power usage is insane. The testing so far done without a patched OS ? And even Intel is not claiming it wins in anything..... YETAnd with that, let the clown fiesta finally begin! When are the reviews due again? I totally forgot.
OTOH they did use high latency DDR5 (4400 CL36). According to Ian, Intel shipped 4800CL40 to reviewers which is just as bad. That could hurt gaming performance in some capacity.Those performance numbers - it's even worse than I expected
Igor Walosek was right, Intel had set PL1 (TDP) to 241W and they used unpatched Windows 11 build, so Ryzen was underperforming
Testing DDR5 4400 CL36 vs DDR4 3200 CL14 for Zen 3/RKL almost certainly does ALD no favors in most of those comparisons, DDR4 is probably the way to go for performance at this time for 12th gen.OTOH they did use high latency DDR5 (4400 CL36). According to Ian, Intel shipped 4800CL40 to reviewers which is just as bad. That could hurt gaming performance in some capacity.
In respect of CML they state 12% better IPC for RKL and 19% on top of this for ADL, that make 33% from CML to ADL, yet the same slide say that the latter comparison is 28%...The part where the 3.3Ghz fixed clock parts showed 19% IPC increase indicates that GC has around 10-11% , on average, higher IPC than Zen3.
Well official specs are official specs. Which means 4800 for ADL on a MB with 2 slots and 4400 on a MB with 4 slots but only 2 RAM modules. Looks like the IMC in general is not that great.OTOH they did use high latency DDR5 (4400 CL36). According to Ian, Intel shipped 4800CL40 to reviewers which is just as bad.

4800 CL36 is part of the JEDEC spec, which they could have used but it seems like most RAM manufacturers are opting for 4800 CL40.Well official specs are official specs.
