Game selection and standard applications
The number of games does not say anything about the relevance and general validity, especially since every user sets his or her very personal premises quite differently anyway. Therefore, a benchmark selection can only be a guideline, but not an absolute judgment. You could hardly make that judgment even after 20 or 30 games, because something always doesn’t fit or, conversely, fits far too well. So today I picked games that were particularly tailored to either AMD or Intel or neither. In addition, the mix contains games that scale extremely well with the CPUs even up to WQHD on the one hand, and on the other hand, games that are partially limited by the GPU already in Full HD and always run in GPU bound in WQHD. Nevertheless, these constellations are also highly interesting when certain CPUs then deviate from this norm and can still achieve slight advantages against the trend.
So it’s not the actual quantity that counts, but the selection. And it won’t be the absolute percentages between CPU results that matter, but the general trend that can be determined over all or most games. If you take the exact metrics (10 per game and resolution!) and look at the power consumption including the efficiency, you can quickly make your own decision about what to buy or not.
For the applications from the workstation or creation area, I mainly rely on full versions of well-known software packages and suites, as well as suitable benchmarks from the industrial sector. That’s why I also do without the known optimization victims like the SPECviewerf and some partial benchmarks of the SPECwpc. Things like Inventor Pro or AutoCAD, on the other hand, are practical and also involve many different real-world workloads and very different load scenarios for the CPU.
Important preliminary remark about the test field and the test setup
As always, I test ALL processors with the motherboard manufacturer’s expedient default options, as they were also communicated by the two chip manufacturers. Therefore, I don’t stick rigidly to PL1 and PL2 with Intel and Alder Lake, but also run the whole thing with PL1 with the motherboard’s respective PL2 corner data. I also didn’t punish Raptor Lake with the motherboard’s all-in setting for water cooling and 4096 watt limit (i.e. unlimited) because of this; the tower cooler’s 288 watts will have to suffice here as usual. If you let the Raptors run quasi freely off the leash, you run into strange limits in some games and applications despite the chiller, which are not temperature-related, by the way. Personally, I also don’t think much of running such CPUs even above 300 watts, so I completely refused here.
AMD can be happy about Precision Boost Overdrive in Zen 3 and Zen 4, which has already been preset by default. The normal user will not manually cap the power consumption to the respective TDP class anyway. I also refer to a counter-test that I once did for AMD’s PBO and that shows that the power consumption does not increase disproportionately in games, but the performance does.
It is also important to me that I test all current platforms, i.e. Raptor Lake, Alder Lake and Zen 4 with DDR5 6000 CL30, which I then use for better comparability. I still use the matching RAM from the last test, which also ran everything stable and without problems via XMP (Intel) and EXPO (AMD). The older AM4 system ran with DDR4 3600 CL14. All CPUs were cooled equally well, at least within the limits of what they allowed. But we will come to the exact test setup in a moment. I have not yet tested other CPUs like the 13 models in today’s review due to time constraints, but I will gladly do so for AMD’s Ryzen 5 7600X and also other Raptor Lake CPUs.
Test setup
I’ll probably rely on a Radeon RX 6950XT for gaming and the application and workstation tests for the last time. The test system for the applications is the same as for the gaming test, with me re-changing everything with and since the launch of the Ryzen 7000 series. It also remains to be seen that DDR5 memory modules are currently slowly establishing themselves in workstations, but that will still be a long way off. The MSI MEG X670E Ace from the Ryzen tests is completed by an MSI MEG Z690 Ace for the Raptor Lake and Alder Lake CPUs and an MSI MEG X570 Godlike for the X570 platform including AM4. I already wrote something about the memory (this time completely from Corsair) in the foreword, and the performance settings are already on page one this time. All CPUs were cooled with my lab cooling (where a chiller and 20 liters of coolant provide a constant 20 °C in the respective CPU water blocks) and for counter-testing with a 360 AiO from Be Quiet! (Pure Loop).
The measurement of the detailed power consumption and other, more in-depth things is done here in the lab (where the thermographic infrared recordings are also created with a high-resolution industrial camera in the air-conditioned room at the end) on two tracks using high-resolution oscilloscope technology and the self-created, MCU-based measurement setup for motherboards and graphics cards (pictures below) or NVIDIA’s PCAT.
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:
