Description

However, as you can see, there are still a few kinks that Intel has yet to work out when testing in Windows 10, such as in our POV-Ray run. It should be noted, though, that those aren't down to outright diminished performance as much as they are the idiosyncrasies that come with using an Intel Core i9-12900K on a Windows 10 system. Alder Lake takes the lead over Ryzen in most workloads, but it isn't a slam dunk in every regard — we ran into several odd performance trends with Windows 10, and a few programs even refused to run correctly.We do expect those issues to be fixed sooner rather than later, though, as the industry adapts to the hybrid architecture. For content creators, the cost proposition of 12th Gen perks up, thanks to several outright wins that prove Intel's 16 cores are, in select cases, just as capable in performance as AMD's Ryzen 9 5950X and Ryzen 9 5900X. But on cost of adoption, the percentages are still skewed in AMD's favor for many PC builders and upgraders. That aspect, and that AMD chips will play just about any game that works on your chosen version of Windows...not whatever gets patched on Windows 11 on a game-by-game basis. Any game, almost any OS. We didn't think that would be a point in the "Pros" column for any processor launched in 2021, but Intel's first major foray into desktop big.LITTLE seems not without its own initial complications. Intel processor numbers are not a measure of performance. Processor numbers differentiate features within each processor family, not across different processor families. See http://www.intel.com/content/www/us/en/processors/processor-numbers.html for details.

We tested the CPUs here on their respective platforms in Windows 10 using a GeForce RTX 3080 Ti card. As you can see from our gaming runs above, things are actually quite close between the two processors, despite 12th Gen's ostensible platform and newness advantage. Between the two, the difference falls nearly within the margin of error for all tests aside from 3DMark, and that score is one that more accurately reflects the system advantage as a whole, rather than just the performance of the chip on its own.

By most of the measures we've gathered here today, it's clear that the move to 10nm and Intel 7 Process has done wonders for Intel's competitiveness on the desktop in mainstream content creation on chips like the Core i9-12900K versus previous generations. But those wins come at a price. The Thread Director (in hardware) can support the operating system to decide which thread to use on the performance or efficiency cores for the best performance.

First up, CPU tests. We ran the various CPUs below (including the Alder Lake chips) under Windows 10, on appropriate testbeds built fresh for this generation of CPUs. (We also reran some of the tests on the Core i9-12900K under Windows 11 to get Thread Director into the mix.)

We also need to close out this section with a caveat: Intel's 12th Gen processors may not work on every single game, regardless of your operating system. During our testing, we found that our Assassin's Creed: Valhalla benchmark title wouldn't boot in. Only after consulting with Intel did we find out this is due to an issue with the DRM service Denuvo, which can confuse the two core types of 12th Gen as two separate systems as tasks shift in and out of the cores. You can read all about the issue, as well as look through a list of the affected titles and their timetables for an applied fix, in our full breakdown here. The issue with games like Assassin's Creed: Valhalla arises either on launch or on load, because Denuvo thinks that the P-cores and E-cores belong to two separate systems, rather than two different core types on the same chip. Once it detects that some portion of the load has been split between the P and E cores, it sees the new cores as a new license holder (a separate system), and force-quits the game to prevent what it believes is two PCs trying to play one game on the same key.

For example, outright thread-punisher tests like Cinebench R23 or 7-Zip will simply max out every resource handed to them, Thread Director or not. This is why we see such similar results between the two whether they're run on Windows 10 or 11, because Thread Director can't be of much help when the only direction on the board is "Give 'er everything she's got."Some programs may also need to be forced to run in the foreground for optimal performance, which Intel advises you can accomplish via the command line using powercfg commands. There's also the more user-friendly Process Lasso that is designed with Alder Lake optimization in mind. That type of intervention isn't ideal for all users, though, especially the casual type, so be aware that Windows 10 could require extra babysitting if you're searching for every last bit of performance.For most users planning on buying an Alder Lake CPU, Windows 11 is the best option. Alder Lake's memory bus has four 32-bit DDR5 channels that create a 128-bit interface. Additionally, unlike DDR4, DDR5 DIMMs come with PMIC (Power Management ICs) chips that control three on-DIMM voltage rails – VDD, VDDQ, and VPP. Yes, competition is good, but only because it pushes AMD to be even better than if they did not have at all. That's the only part I care about.I can respect your opinion, but I disagree. In my opinion companies all do what they can to stay as profitable as they can. Consumer "goodwill" is just another currency these large multinational companies spend and receive for various conduct. AMD currently has a decent amount of goodwill, however, they spent a major chunk of it by not releasing a 5600, 5300, 5700 / 5800 while also increasing prices by 50 dollars across the board. They did this for money and they knew they could get away with it because they had garnered enough consumer goodwill. Leveraging Intel's so-called "7 Process," the company's launch of its new 12th Generation desktop CPUs sees the new chips built on 10nm lithography, finally breaking the company out of its half-decade love/hate affair with the 14nm process and its subsequent "14nm+"-based iterations that followed for years after.
