Today we want to question where the upcoming Core i5-12400 can still score apart from colorful gaming worlds and whether it will remain just as frugal and efficient. Gaming is actually overrated when you take a closer look at the benchmarks from 1440p. Thus, the true strengths of the new architecture will hardly be seen while gaming, but I wonder if it will still look like that in the workstation test and without the small E-cores.
Even though I’m not under NDA, I’m remaining fair enough in today’s follow-up to deliberately use an emulated CPU and none of the Engineering (ES) or Qualified Samples (QS) that were helpfully offered to me outside of the Intel influencer universe. However, I took the liberty to check an important part of my results with a QS (QYHX) for plausibility, so that I really get everything exactly right.
For today’s test, I deliberately use the same platform as the day before yesterday for gaming, also with identical settings. This also makes it easier to compare where your preferences are better placed: gaming or working. Or maybe even both, who knows? And even though the Core i5-12400 available in January might not be that great in terms shelf availability – for today’s test I set a current Core i5-12600K in terms of base clock (2.5 GHz) and turbo clock (4.4 GHz, 4.2 GHz as well as 4.0 GHz allcore) along with the voltages and power limits (PL1 65 watts, MTP 117 watts) exactly as the specs, BIOS and XTU say for the real non-K processor, but did not set the PL1 to the PL2.
But that yieled NO gains in the work environment anyway, I tested that of course. But let us surprise you today, what can be done without the E-Cores (or not). The in the original not available E-Cores could be completely deactivated in the BIOS also with the Core i5-12600K, so that I could test a perfect (emulated) copy of a not yet launched i5-12400 here. The fact that the cache is minimally smaller in the QYHX has virtually no relevance in practice. So today there are again “only” the values of my blueprint.
In gaming, it’s usually the graphics card that slows things down, in productive use and especially in design and construction, it’s almost always the CPU. I’m using an NVIDIA RTX A6000 for testing, which also wants a snappy underbelly when outputting real-time 3D views, whether it’s using OpenGL or DirectX. Many CAD programs are even worse than the nastiest 720p gaming test in this regard, cue AutoCAD. But I’ll get to that in a minute. Solidworks and Inventor Pro are also demanding, but contain very different workloads ranging from light to hammer-hard, which can sometimes occur at the same time. This is where Alder Lake S should be able to play to its strengths, which will have to be proven even without helping E-cores.
And I also have to preface this test with the fact that the current Ryzen CPUs, first and foremost the comparable Ryzen 5 5600X, are not degraded to silicon waste with today’s release and you also don’t have to have any reason to panic about suddenly not being able to work with them from one day to the next. Only the efficiency has to be practiced again with AMD, because Intel has really delivered a new benchmark with the Core i5-12400 in gaming. But let’s be surprised, I won’t spoil anything yet.
Benchmarks, Test system and evaluation software
The measurement of the detailed power consumption and other, more profound things is done here in the special laboratory (where at the end in the air-conditioned room also the thermographic infrared recordings are made with a high-resolution industrial camera) on two tracks by means of high-resolution oscillograph technology (follow-ups!) and the self-created, MCU-based measurement setup for motherboards and graphics cards (pictures below).
The audio measurements are done outside in my Chamber (room within a room). But all in good time, because today it’s all about gaming (for now).
I have also summarized the individual components of the test system in a table:
