The 7950X also has only 1MB of L1 cache, and the 13900K has 2.1MB of L1 cache. It seems that we're seeing something we've seen in the past; more cache means you gain less from fast RAM.

I'm so glad you included the latency formula around 4:15. That latency actually tells you what kind of chips the memory has and the timing is basically manufacturing tolerances for the wiring. DDR5 6000 MT/s CL30 has literally the same memory chips as DDR5 6800 MT/s CL34, just different XMP profile. That's why checking out that CL number is so important while buying RAM. And the general rule is that if the software (game or app) is written so that the most used data fits in the L1+L2 cache, memory latency doesn't matter and bandwidth is more important. If however, you're running software that needs to access more data than can fit in your CPU cache, higher latency memory will hurt a lot. As most users have high latency memory because it's cheaper, well optimized games typically run just fine with high latency memory. However, if your favorite game happens to be poorly optimized one, you'll be out of luck with high latency memory. I'd say go with the cheapest DDR5 RAM that can get you around 12 ns using the formula at 4:15.

The subtimings have the biggest impact on performance, far more than the CAS latency has. First word latency is also a bit of a misnomer, it only applies for an already open row, a large proportion of memory accesses require you to open the row first so RCD has to be added before CAS to get the latency of the operation. Also, back to back memory operations are probably the biggest latency penalty, these all are limited by the subtimings.

Intel is literally just the difference from faster ram. Back in the DDR4 days, AMD’s infinity fabric would be tied to the speed of the ram. That’s why higher ram speed outright overclocks the CPU. It is likely that this continues to be the case with DDR5, although I am not sure. You can also see the 5800X3D not caring about higher ram speeds because the additional cache reduces the need to care about latency and bandwidth from the ram.

It absolutely makes sense of you know how ram works. The chip takes X amount of NS to do something. The module manufacturer will choose speed at which the chip can run, and calculate the number of cycles the operation will take at that speed, so it covers the same amount of time in NS. For example an operation taking 13.3 ns takes 24 cycles at 3600MT and 48 cycles at 7200 MT, and the performance will be more of less identical.

Good old days. Back then I bought and sold quite a few Corsair Dominator GT 2x2 and 3x2 GB kits, always looking for Rev. 7.1A kits. They had the good ICs on them. With water cooling (they didn't like sub-zero temperatures, but also not when they got hotter than 50°C) I could run them at about 2050 MHz and CL6-7-6-20. What a great time, and always selecting out which module is now the bottleneck. Such nice memories. Oh how I miss those days when you could afford PC hardware without having to sell your kidney. Today all the junk is so expensive and yet none of the sets shown come close to the 5.85ns of my Dominator GT.

Wendall from level1tech's mentioned that the internal memory controller (IMC) is what Intel binned for with the 13900KS vs binning for the P cores in the 12900KS. I wonder if the 139ks with the better IMC would show bigger gains during gaming at higher RAM speeds. Wendall also mentioned that 5800X3D didn't see much difference in performance with 3200 vs 3600 mhz ram. I wonder if that will stay the same for the 7000 series x3d cpu's.

Great video! I just wanted to chime in on the discussion about RAM speed and latency. It's important to note that RAM speed, measured in MHz, determines the number of transfers of data per second, while latency, measured in nanoseconds, determines the time it takes for the RAM to respond to a request for data. When building a computer, it's crucial to strike a balance between these two factors, as having too much of one and not enough of the other can lead to bottlenecks in performance. Thanks for enlightening us on this topic!

Got the "G.Skill Trident Z5 Neo Series 32 GB (2x 16 GB) DDR5 5600 MHz CL28" last December for under 200€. I paired it with a Ryzen 9 7950X. Happy to see I made the right choice. Although it was a pain to have the kit recognized by the MSI motherboard, and I even had to update the BIOS to make it accept a second kit that I bought later to reach 64GB or RAM.

im not 100% sure how its with DDR5 or your Mainboard+7950X but be aware that it usually was better to have 2x 32GB modules than 4x 16GB modules. Yes, its a kind of more cheaper upgrade path if you REALLY(!!!) need this amount of RAM. Performance whise its better to stick with two sticks because Dual Channel performes better than quad channel mode. And in addition to that more cheap/mid-range Mainboards and CPUs dont always offer you the max speeds with 4x Sticks. For example: My younger brothers PC has a Ryzen 2700X with a x470 board(Msi Gaming Plus). The board specs say: DDR4 MEMORY: 1866/ 2133/ 2400/ 2667 Mhz by JEDEC, and 2667/ 2800/ 2933/ 3000/ 066/ 3200/ 3466 Mhz by A-XMP mode MEMORY CHANNEL: DUAL DIMM SLOTS: 4 MAX MEMORY (GB): 64 He has 4x 8GB 3200mhz sticks inside and judging by the mainboard specs XMP/EXPO mode should work perfectly fine for 3200mhz. But the reality is that it seems those specs only are valid for a dual-channel (2x Sticks) configuration. When trying to enable XMP/EXPO with 4x Sticks to 3200mhz the system is incredibly unstable and it basically doesnt makes any sense to run it in this mode, hence loosing performance which you paid for the RAM. Only 2933mhz speed worked stable for 4x Sticks.

Like 64GB (2x 32GB sticks) seems to come with slower CL than 32GB (2x 16GB stick) kits; does the extra RAM space offset the lower CL in gaming performance? I'm planning on getting a AMD 7950X3D when they come out later this month. I was planning on getting a DDR5 64GB RAM kit, to use in this new rig which is primarily a gaming PC with an RTX4090. Any specific suggestions on the best 64GB RAM kit?

RAM capacity doesn't directly impact performance at all, if you have enough RAM you have enough. 64 GB is directly counterproductive if you don't need it for productivity workloads, since as you point out the kits are slower. 16 GB is just barely enough (the minimum requirement for new games), 32 GB is the sweet spot.

While I think there are many aspects of Korean culture I don't yet grasp, respect does appear to be a very important concept from what I've experienced. There does seem to be a concept of being respectable (in non-verbal ways indicating your own worthiness/capacity-for of being respected by others). With respect to this SSD, if the read and write performance has different metrics when it is being respectful and when being respectable, it would be good to know the respective metrics. I mean this in jest, and in a most respectful way - writing copy that would be scrutinized by the internet (and your audience is probably more pedantic than most) seems like it would be a special kind of torture.

I figured I could upgrade later if speeds and latency got better. I am running 64Mb and doing primarily rendering and production work (database and site development as well as graphics but almost no gaming so only went with a 3080ti). So far the 5600 Cl28 has really impressed me.

Some say that DDR5 consumes less power, but does that hold true in practice? Apparently for the same given frequency (ex: DDR4 4000mhz vs DDR5 4000mhz) , DDR5 consumes less power as DDR5 Voltage is 1.1 while DDR4 voltage is 1.2 (XMP off) to 1.35 (XMP on). However new generations of ram have WORSE performance for the same given frequency, so basically DDR4 3200mhz = DDR5 5000mhz (or something close to that) performance-wise. So my noob question is basically- won't the higher frequency of DDR 5 necessary to achieve the same performance of lower frequency DDR4 cancel out the benefits of DDR5 running at a lower voltage? Thank you.

CAS latency is one of the least important timings for RAM, but is probably the most easily-marketable. First word latency is rarely what matters in real-world performance. No real workload has purely-random access patterns. AIUI what tends to matter more is the latency between commands (Read to Read, Read to Write, etc.) in the same bank or bank group. It *does* represent worst-case (or near-worst-case) performance so it has *some* utility but real-world applications rarely present a worst-case scenario - RAM, like most hardware, is designed to perform well for typical usage after all.

I'm not upgrading to DDR5 unless the out of box performance is better since I manually tuned all the way to tertiary timings on this kit and I no longer have the time to spend manually tuning timings anymore. However, an X3D chip might make that a moot point if they can run a 6400 kit with decent timings out of the box. The extra cache makes the boost from OC-ing RAM not so huge.
