    [VideoCardz] - Intel 4th Gen Xeon Scalable "Sapphire Rapids" CPU die shot leaks

    Posted: 12 Jun 2021 08:28 AM PDT

    Some time ago Dr. Ian Cutress posted a video regading RAM memory MHz vs. MT/s, but I'm having serious trouble applying said knowledge to DDR5 for a few various reasons. Care to help me understand DDR5 better ?

    Posted: 12 Jun 2021 06:43 AM PDT

    This is the video in question. This will be a bit of a mess, but please bear with me, I need to explain a few things in order to make clear why I am confused.

    DO NOTE that I could be completely misinterpreting DDR5 specs, but that's why I am here, to learn.

    So let's take DDR4-3200 - from what I've understood in his video, there are 3 ways it can be addressed:

    DDR4-1600MHz

    DDR4-3200MT/s

    or the least confusing of the bunch

    DDR4-3200

    Why ? Because of the D in from DDR, meaning Double Data Rate, which means two data transfers per clock cycle, which means that DDR-3200 runs at 1600MHz, and the reason it's called 3200 is because of it's maximum potential in terms of Mega Transfers per second.

    But then, how the hell are you supposed to interpret the number after DDR5 ?

    You see, things got complicated with DDR5, since now you can have both read and write at the same time, so doesn't that mean that, "potentially", DDR5 in a perfect scenario would be the same as a Quad Data Rate due to this new technology ?

    Of course, emphasis on potentially, since you'd need the software to be perfectly optimized on top of the task needing to both read and write at the same time, but this brings me to why am I confused:

    ​

    How do you read DDR5 speeds in accordance to what Dr. Ian Cutress was talking about ?

    For example, how do you read DDR5-12600 (the biggest speed announced so far)

    Is it DDR5-6300MHz ?

    Because we were saying that MT/s refer to maximum potential in the case of DDR4, do we call it DDR5-25200MT/s ?

    Do we only refer to one action at a time since not all programs require both reads and writes at the same time, neither can the best of them fully utilize this potential, and as such DDR5-12600MT/s, in other words, DDR5-12600 ?

    All of the above ?

    Again, I could be very wrong, but that's because I don't know how we got to that number with DDR5, and what role does the new read/write tech pose in Potential Maximum Mega Transfers Per Second.

    ​

    Thank you for your patience.

    ​

    EDIT: I have read all the comments thus far and I strongly appreciate your answers. It has greatly helped my understanding of DDR5. Basically, to compare DDR4-3200 and DDR5-3200 we shall use the door to a theater as an example. The door itself is as big as before (in this example), but now the corridor is split in half if there are both people leaving and coming (note, both corridors could be used for the same action). This is an increase in efficiency compared to DDR4 where people could either only come or go, so you had to wait your turn.

    ADDITIONAL QUESTIONS:

    1). Are there any possible, hypothetical scenarios where this could lower performance ? Note hypothetical, since I doubt it would be a common occurrence, especially since the speeds are getting incredibly high.

    2). How does this compare to DDR Channels (i.e. dual channel, quad channel, etc.) and how do they interact with them ?

    What is the theoretical data rate limit of a DDR5 DIMM slot?

    Posted: 11 Jun 2021 06:52 PM PDT

    I have found zero information on this. Basically, every slot on a motherboard has a limit, correct? USB4 is 40Gbps, PCIe 5.0 16x is ~64GB/s, and I would guess even a CPU socket must have a data rate limit depending on pin/pad count. So what is the maximum data rate limit of a DIMM slot, say a DDR5 one? If there is not enough information on DDR5, DDR4 is okay as well.
