Synthetic System Benchmarks

We are going to start with synthetic system application benchmarks on this page. Gaming performance will be shown later on. DDR4 RAM vs DDR5 RAM is being compared on each graph on the same CPU, DDR5 is the orange bar and DDR4 is the blue bar.

3DMark

CPU Profile

Intel Core i5-12600K Alder Lake DDR4 vs DDR5 Performance 3DMark CPU Profile Max Threads

We are introducing a new test into our suite, we are using 3DMark Professional’s CPU Profile test. This test specifically tests CPUs and reports an overall score, it tests various thread counts. We are going to report on the “Max Threads” and “1-Thread” results only. Right off the bat, using Max Threads on the CPU this test reveals no difference in performance between the DDR4 or DDR5 platforms. The motherboards are different, so this could account for tiny differences, but there is nothing blaring from this test to show that either platform has an advantage because of the RAM type.

Intel Core i5-12600K Alder Lake DDR4 vs DDR5 Performance 3DMark CPU Profile 1-thread

In the single-thread testing, we also find absolutely no difference in performance between DDR4 or DDR5 in this benchmark.

Geekbench 5

Intel Core i5-12600K Alder Lake DDR4 vs DDR5 Performance Geekbench 5 Multi-Core

Next up we have the latest version of Geekbench 5.  This benchmark tests overall CPU performance and can show us a result in both multi-core and single-core performance. This is the first evidence that DDR5 does make a performance difference. Geekbench, unlike 3DMark, tests a variety of workloads, whereas 3DMark is simply a single workload type. Therefore in multiple different workload types, and in multi-core, we are seeing DDR5 perform 9% faster than DDR4. That’s no small amount, that kind of performance difference is significant, and noticeable.

Intel Core i5-12600K Alder Lake DDR4 vs DDR5 Performance Geekbench 5 Single-Core

In single-core though, we are back to there not being a difference, it swings a little more toward the DDR4 in fact, perhaps due to better timings? It’s not significant though.

  1. How is that MSI cooler doing? CPU cooling for alder lake is my main big question atm and MSI liquid coolers seem to be one of the few that are compatible that I can get over here.

    Especially worried after reading that article where they show bent CPU heatsinks with dodgy cooler mounts.

    It’s the best cooler that I’ve had on the test bench (on the 10980XE though). I’m sure Brent has better feedback on Alder Lake specifically…

  3. I’ll have more experience in the near future, have it installed on a 12700K right now, and then 12900K, so far as far as the 12600K goes it went real well, and that CPU stayed cool very well with it, however, I have been running it on 100% fan speeds for testing purposes, so it’s loud. I will be getting to temp testing on the 12700K soon, and then 12900K ,and we’ll really see how it holds up. As for bent heat spreaders, haven’t noticed anything odd. I will say though that with the screws screwed into the backplate it’s a lot looser than I would have thought it would be, or I should say, compared to other coolers, but it’s not a problem once you screw down the block on top of the screws with the thumbscrews, it tightens up nicely, and you really can’t over tighten it, it has a natural stop. Make sure to check in next week to see how the temps on the 12700K did, then in a couple more weeks the 12900K.

  4. I will leave a link to the article I read, it’s kind of though to read guess it did not translate well but found it interesting. [URL]https://www.igorslab.de/en/bad-cooling-at-alder-lake-problems-at-socket-lga-1700-on-the-lane-among-all-remedies/[/URL]

    Does look like the risks are bigger with cheaper boards.

    That’s par for the course for a number of reasons. That being said, I did notice that the back plate EK offers for it’s LGA 1200 / 2066 socket waterblocks is much thicker and beefier than what I’ve seen on pretty much every generation going way back to the pre-Sandy Bridge era.
