Re-examining the DDR4 gaming gap with Intel’s LGA 1700 CPUs in mid-2026 — performance drops of 14% on average, and up to 25% in some games

DDR4 vs DDR5

Unless you already have a kit of DDR5, or deep pockets for PC hardware, you’re stuck right now. Despite seeing some of the best CPUs for gaming released just in the past year, the DDR5 tax represents a major hurdle to building or upgrading your PC. Intel’s LGA 1700 CPUs hold an unintended solution, offering support for both DDR4 and DDR5. We wanted to see if this on-ramp to a next-gen platform was really as smooth as it looks at first glance.

The idea is simple. If you already have a DDR4 kit, you can upgrade to a relatively new CPU while keeping the door open for a transition to DDR5 without buying a new chip. It’s inexpensive, and a bit more of a practical solution than upgrading to DDR5 with a single DIMM and worrying about pairing it with another later.

    It is slightly disingenuous to use DDR4-3200 and DDR5-7200 : one is the 'sweet spot' from way back in 2018, the other is top of the line O/C from right now. DDR4-3600 vs. DDR5-6000 would make a lot more sense.

    Not really. Because the testing is only with games, and its been pretty much shown ad nauseam that games aren't greatly impacted (DDR4 3200 vs 3600, DDR5 6000 vs 7200) with the frequency, not sure we'd see a significant difference if he had used your suggestion.

    I'm surprised nobody looked at the number of memory sticks in the test setup and focused entirely on MT/s. The DDR5 rig is 2x16, the DDR4 rig is 4x8!!! Seeing that I am beginning to doubt that the 12th gen CPUs will show any very meaningful delta if the RAM kits were somewhat comparable physically, given that their memory controllers are reportedly weaker and might have struggled more with the 4 sticks of RAM.

    That's a good point. The test probably should have been more comparable with this and @mitch074 suggestion. However, I am looking at other tests comparing DDR4 and DDR5 in games, and the results are similar or within margin of error.

    Let's put a positive spin on this: Intel increased cache and memory controller capability to improve performance generation over generation, widening the gap intentionally, but not to kill DDR4, but where there was potential to do so meaningfully. I bought my hardware new a year ago dirt cheap from today's perspective: Intel Core i7-12700, 2x16 @ 3600 MT/s, Intel Arc B580. I'm obviously not a gamer. But I am amazed at how well it is holding up and continues benefiting from Xe architecture development. I do agree, though, that if you are a serious gamer, the time to build a DDR4 system has passed a while ago, and I would probably not get new parts for such a system nowadays.

    If the IMC can handle 4x8 DDR4 without issue at its rated clocks, which it can, there's no reason that I can think of that would prevent this being a fair comparison. If the IMC had "struggled" with the DDR4 it wouldn't have been stable or worked all that well,

    I think I was very careful in my remarks and would place 'might have struggled' from a performance perspective a quiet but far cry from instability. Quite the opposite: They worked quite well, so imagine what DDR4 could have done in an optimal configuration... Looking at how people complain about a single RAM stick configuration for their Stream Machine, dismissing daisy-chained RAM sticks as irrelevant in a comparison of RAM generations, which others agreed might have skewed results a little bit, is not much supported by the absence of a system crash, in my humble opinion. But yeah, it's beautiful to see that 12th gen Intel handles a 4x8 @ 3200 MT/s configuration without crashing. Point taken.

    Because of the high price of RAM, many users can't afford to care much about the gap between DDR4 and DDR5.

    Maybe the game developers need to wake up and start to optimize their code like they did years ago. Now days they just churn out content and expect the hardware advancements to bail them out.

    The game developers need to realize that if people have to buy DDR5 based machines they will not have as much money left over to buy games. Someone wanting to play their game will think twice if the game costs $30 but they have to spend $500 for memory first.
