Test Bed and Setup: Moving Towards 2024

As per our processor testing policy, we take a premium category motherboard suitable for the socket, and equip the system with a suitable amount of memory running at the manufacturer's highest officially-supported frequency. This is also typically run at JEDEC subtimings where possible. It is noted that some users are not keen on this policy, stating that sometimes the highest official frequency is quite low, or faster memory is available at a similar price, or that the JEDEC speeds can be prohibitive for performance.

While these comments make sense, ultimately very few users apply memory profiles (either XMP or other) as they require interaction with the BIOS, and most users will fall back on JEDEC-supported speeds - this includes home users as well as industry who might want to shave off a cent or two from the cost or stay within the margins set by the manufacturer. Where possible, we will extend out testing to include faster memory modules either at the same time as the review or a later date.

Our CPU 2024 Suite: What to Expect

We recently updated the CPU test suite to our 2023, but we've decided to update it again as we head into 2024. Our new suite has a more diverse selection of tests and benchmarks, focusing on real-world instruction sets and newer encoding and decoding libraries such as AV1, VP9, and HVEC. We have also included a range of AI-focused workloads and benchmarks, as we're seeing a direct shift from manufacturers to incorporate some form of on-chip AI processing, such as Ryzen AI and Intel's Meteor Lake AI NPU.

While we've kept some of the more popular ones, such as CineBench R23, we've added Maxon's latest CineBench 2024 benchmark to our test suite. We have also updated to the latest versions (at the time of incorporating the suite) in benchmarks such as Blender, V-Ray, and y-Cruncher.

With our processor reviews, especially on a new generational product such as Intel's Core i9-13900K/14900K, we also include SPEC2017 data to account for any increases (or decreases) to generational single-threaded and multi-threaded performance. It should be noted that per the terms of the SPEC license because our benchmark results are not vetted directly by the SPEC consortium, it is officially classified as an ‘estimated’ score.

We've also carried over some older (but still relevant/enlightening) benchmarks from our CPU 2023 suite. This includes benchmarks such as Dwarf Fortress, Factorio, Dr. Ian Cutress's 3DPMv2 benchmark, Blender 3.3, C-Ray 1.1 rendering, SciMark 2.0, and Primesieve 1.9.0. We've also kept UL's Procyon suite as a more holisitc system-wide test.

As for gaming, we're currently still revamping our CPU 2024 games suite, and as a result, we've tested gaming against our CPU 2023 suite. You can rest assured that our CPU 2024 games suite will be uploaded to the latest titles and will include even more technical aspects in play, such as Ray-Tracing, as this directly impacts CPU performance and frame rates. We will also include a similar methodology in terms of resolutions, including 720p/lower, 1080p, 1440p, and 4K.

We are currently using our games from our CPU 2023 suite. Our current games in our CPU testing and those featured in this review are as follows:

  • Civilization VI: 480p, 1080p, and 4K (both avg and 95% percentile)
  • World of Tanks: 768p, 1080p, and 4K (both avg and 95% percentile)

  • Total War Warhammer 3: 720p, 1080p, and 4K (only avg fps measured)

As mentioned, we are updating our CPU 2024 suite with new games, including some of the latest titles. We are currently testing them, and they will be ready as we review the next generation of CPUs from AMD and Intel. 

While we normally analyze Core-to-Core latency on new CPUs, the fact that Intel's 14th and 13th Gen are identical architecturally, we opted to omit this from our testing. This also goes for the Core i9-14900KS we are reviewing today, as technically, it is the same architecture and silicon under the hood.

    Right next to https://www.anandtech.com/show/21392/amd-hits-reco... at the front page at the moment.

    Dangit, here I was gonna have a walk down memory lane and the benchmark images are all missing.
  • edwpang - Friday, May 10, 2024 - link

    History repeats itself, 20 years ago, Intel Pentium 4 Prescott increased clock speed, but no much performance gain:

    Yeah but Intel has gone full insanity here. If Prescott could heat my dorm room in college, the Raptor Lake on juice should be able to heat an entire house. This is over 3x the heat output of the hottest Prescott!
  • GeoffreyA - Saturday, May 11, 2024 - link

    That's the thing. Prescott has this reputation, rightly so, but I don't think it went over 200 W. Cedar Mill further curtailed the TDP.
  • boozed - Sunday, May 12, 2024 - link

    I'd love to have seen some specific performance results, i.e. performance/watt or work/energy.
  • Samus - Tuesday, May 14, 2024 - link

    AT did some testing on this last year and the short of it is unsurprisingly AMD scales up AND down better than Intel when it comes to performance per watt, but Intel can hit higher TDP's due to limits AMD has on their package power.

    Would have liked to see this review done at the Intel dictated stock settings rather than the motherboard defaults.

    Don't worry; I will be testing Intel Default settings, too. I'm testing over the weekend and adding them in.

    I tested, as we normally do because it keeps the data set consistent. As I state on the first page

    "This does pose questions when it comes to testing and reviewing Intel's 14th and 13th Gen processors. We have been considering our standpoint on this, as we will typically test at the default motherboard settings with memory set to JEDEC specifications of the specific processor we're testing. For this review, we will be testing how we usually test, as this fits within the realm of keeping things consistent."

    Intel's back-and-forth with motherboard vendors on this issue has raised many questions. We intend to address it as soon as possible. We already test with memory as per JEDEC, and I usually get a lot of criticism about why I don't test with DDR5-6000 or DDR5-7200, etc.

    Don't worry, we will be addressing this in-house.

    I am expecting reviews to start fixing Intel's inaccuracies, not "keeping things consistent". Using an overclocked CPU, at an overclocked state in a review, helps maintaining inconsistency not consistency. Especially when there is a chance the CPU to get degraded even in the short period of warranty time. The fact that this is pre overclocked CPU from Intel, doesn't mean it should be tested that way, especially after the latest revelations. Whatever data you had, should have gone directly to the trash bin and only test with whatever Intel believes it is "in spec".
