I dont think DDR5 will matter for most people at the start. It will probably take few years before it gets wide spread penetration. Especially with how the hardware market has been the last year an a half. 

I think you're underestimating peoples thirst / desire for everything  new ... as soon marketing starts to push this people will buy, especially if its that cheap, and even with price hikes nothing will stop them.

New cpu, mobo, ram , all thanks to the "competetive" fps craze .

 

idk back in my day we competed by skill, not by who has the most fpsss…

WOW DDR5. Hell I remember when SDRAM was current. I got some DDR 1 memory hung on the wall with the motherboard from my first gaming machine. 

I feel kinda dumb for buying Samsung "B-die" Ram this week, but i knew ddr5 is around the corner, and in hindsight it probably wasnt dumb, my pc somehow feels a lot snappier, and i finally oc'd Ram, which was utterly impossible with the weird corsair Ram i had (plus PC feels a *lot* snappier really)

 

But, yeah, im ready, i guess, next year new mobo/cpu/ram seems reasonable*, depends on how hot the intels run, prob not going to go Ryzen again, way too many small, but annoying issues.

 

*but… that also depends on how my pcie4-less mobo holds up tbh…

With all the shortages its going to be a cluster fuck mixed with a shit storm.

I'm getting some 128mb DDR1 RAM in the mail this week, for a retro laptop... and still use DDR3 1333.

In all the pics i've seen of ddr5, it's always shocking how small the modules themselves are.

My Plex server has 16 Gigs of DDR3 in it. Not sure on the rated speed.

Agreed, thats entirely possible, in which case ill happily keep using my outdated, last gen, high end stuff.

I've got a strange setup, 8x4gb ddr3, in 8 channel mode. I could put 12 channel ddr3 in it, but then since one CPU has 8 ram slots and the other only has 4, it would still technically be in 8-channel but CPU 0 would have more memory to handle... (Yes this is a workstation dual socket board)

it'll be big for the laptop market I think. Lower power RAM and the faster speed will benefit laptops with an integrated gpu a lot more than it will a regular desktop system.

Some really large UDIMM capacities coming soon by the looks

Burst length is also being doubled from 8 to 16 on DDR5 which has many implications. The most notable being an effective doubling of memory bandwidth (being able to send two 32-byte operations in the time DDR4 can deliver one).

Under synthetic ram benchmarks like Aida64, we can already approach quite close to the theoretical peak transfer rate of DDR4. Such benchmarks are multi-threaded and designed to maximise throughput. There doesn't seem to be enough room to double bandwidth, unless we look at different scenarios. Can I assume the benefits of a longer burst length might affect "regular" software more than such synthetic benchmarks?

The biggest unknown is whether this bank-based rank interleaving performed on-DIMM will stack with traditional rank interleaving done across different DIMM's on the same channel. I am genuinely excited for DDR5 because even at these slowest speeds, we should see significant gains in overall feel, not counting what we will see when overclockers get their hands on it.

A potential confusion point I've yet to wrap my head around is that the DDR5 modules will each have two channels of half the current width. Overall it would seem not to provide more peak bandwidth in itself, but is this a contributor to these rank/bank effects you describe?

That price is for the scalpers - We'll probrably have to pay them $999 per stick for these.

$999 wow your feeling generous today I'm thinking $1200 get that 3x MSRP

Dynamic Random Access Memory (DRAM). Part 6: Burst Mode and Bank Interleaving (a bit slow, but talks more about banks at the end)

Not sure if those will help, think it was they are going todo the same way as from DDR3 to DDR 4, just to DDR 5? with their own power filtering?

Nope. The 2nd one has many technical errors in it.

My understanding is that while there are no desktop motherboards that take these things currently there are a bunch of servers that do so.  They will generally want ecc memory though.  Ddr5 seems to have a sort of partial or quasi ecc baked in and I am noticing no heat sinks to print branding on, so I wonder if this is server memory being remarketed or something.  One question would be whether these things have the full ecc or this new partial version.

Not so fast,

Those DDR5 4800MHz CL40 modules are as slow as DDR4 2400MHz CL20 modules.

That’s what generally happens.  When a new ddr version comes out it is at first even slower than the previous version.  Tends to pick up later though. This wouldn’t be memory I would particularly want to buy.

Yeah that sounds about right. Actually that sounds more scary.

If you look at history going through the ram generations, you'll find latency (as time, not cycles)) remains about constant in like for like modules classes. So compare standards based timing with standards based timing, and enthusiast timings with enthusiast timings. You still get the massive change in bandwidth which is still highly desirable for a lot of use cases. For most of my use cases, bandwidth makes a much bigger difference than latency.

 

Also looking at the ram latency in isolation doesn't help, you have to consider it at a system level where the CPU makes a big difference too. I don't know if Zen 3 has changed things but I do recall Zen 2 had notably worse latency than Intel CPUs of the time. I think it is more a design decision needed by AMD to enable their core scaling. It also doesn't matter much since they mitigate with big L3 caches.

Dang I wasn't expecting DDR5 consumer availability until ~ the end of this year.

I cannot wait for AM5 Rembrandt APUs using RDNA2 paired with faster, more mature variants of DDR5.

As someone who has not yet updated I am also interested, if only to be able to skip yet another apparently this time fairly short lived hardware generation.

yes ;(

Although the first generation of this is likely going to have some issues? hopefully it goes smoothly in first or second generation with that tech.

and what it might bring.

There is that. Coming up on a v1.0 again.

iirc it takes a couple generations for the next ram generation to end out having an improvement over the last one. So you are mostly fine
