Hi i wanna buy new system.

So for deciding what motherboard/ram i buy, Im between 3600mhz 18cl and 6000mhz 30cl.

I need for video editing 64gb.

6000mhz costs 250Euro more. Is it worth it, if i work full time?

If it makes you money it may be worth it; after all it is less than a Euro a day for a year.

Check reviews for editing software benches. From my experience with DDR5, you can save quite a bit of time, which means more work can be done in the same period, which means more money in the end.

Going with a Intel system I assume? New AMD is DDR5 only.

If you are doing CPU workloads, there isn't much of a difference.

If you are playing games, DDR4 has the advantage is some titles, and a lot less in others. but really once your GPU bound, its doesn't make much of a difference either.

Yeah for productivity DDR5 is almost a no brainer, for gaming it's a toss up between the lower latency DDR4 and the higher bandwidth DDR5, which is faster on average, but not by much.

6000 MHz DDR5 is a good spot IMO. More than that isn't really possible on AMD for example, and is very expensive although possible on Intel.

Remember the DDR5 motherboard will likely also cost more, so factor that in, not just the RAM price.

If all you're doing is video editing, maybe look into 5800/5600 MHz DDR5 if that's much different in price, the 2-400 MHz won't make much difference, and you're not guaranteed to get 64 GB of 6000 MHz working anyway, since higher capacity is harder to run at high speed.

It would be easier to give you advice if you shared the rest of your planned system and it's platform.

But based on this


I think it should be max 10% in some Scenarios. Which is joke for 250euro..

I would get the Prime TX/PX 850 instead, a 13600K+7900XTX won't use more than 650W in full synthetic load.

Go for slightly lower than 6000 MHz DDR5, anything above 5000 is pretty fast bandwidth wise.

To me this is a no-brainer - regardless the intended us of the computer.

When buying brand new - go for the latest technologies your budget allows. If you opt for the old standard, DDR4, you will be stuck with old standard motherboards and old standard CPUs. Why limit your future update options like that.

"IF" DDR5 was a brand new, unproven technology just released today, then your question would be valid. But DDR5 was released way back in June 2020 with consumer products hitting the market in late 2021.

2023 is just 5 weeks away and DDR5 is here to stay.

History has shown us, over and over again, when new RAM technologies start to dominate the market, more and more, and soon all the RAM factories will have retooled to make the latest RAM. Then what happens? The older technology RAM becomes harder and harder to find (and often more expensive too) - unless you take your chances and go used.

So no brainer. Go DDR5.

Imo its not about new technology but benefit. Its 250 euro for 5-10% performance. Maybe im missing something but i dont think its worth it

Hi,
Not worth 250 more for sure
But 3600c18 is mediocre at best c16 or lower being best in ddr4 land seeing frequency goes up say to 4000 and latency goes down more with some tuning.

ddr5 I'm sure can be tuned a lot to but prices and latency are shit still.

Whatever is cheaper by a significant amount. Easy answer. DDR4 is reaching EOL. Give it 2-3 years and only JEDEC 3200 will be found for sale.

It is not about new technology. It is about the "current" technology AND how far that will carry you into the future.

No doubt, this is about predicting the future. But when you study the past, the future becomes pretty clear.

Let's say you buy a DDR4 platform today. That means you must buy an older, superseded technology motherboard that supports, what is becoming "legacy" DDR4. And of course, you must buy a CPU that same soon-to-be legacy, motherboard supports.

What if, in 2, 3 or even 5 years, you decide to add more RAM? Or upgrade to faster RAM? Will you be able to find new DDR4? Maybe not. Or let's say you want to upgrade your CPU. Will you be able to find one that is still supported by that "legacy" motherboard? Maybe not. So instead of allowing your computer to "evolve" in small, affordable steps that keep you current and carry you further into the future, you may be forced to buy all new again.

In the long run, you end up spending more.

So yes, as a "tactical" short-term buy, going with DDR4 today will likely save you money today. But "strategically" you likely will end up spending more in the long run because you will be forced to upgrade the entire platform sooner.

If spending €250 more today saves me €500 (or considerably more!) down the road, if my budget allows, I will, without hesitation, spend that extra €250 today.

Don't forget the added three-fold, "warm fuzzy" factor. First, DDR5 offers better performance. Second, DDR5 is more efficient. And last but not least, third, if you go with DDR5, you will not look back with regrets wishing you had treated yourself and gone with the DDR5.

Keep in mind that with more speed should come more performance. The source you show does not apply to your situation as you are not looking for 4800C40. Also, while I have yet to test this myself, I am seeing that the 13-series performs slightly better than 12-series chips with RAM.

I run a 12-year-old computer but am still one for keeping up with technology when replacing; you don't want to lock yourself into a DDR4 mother board, and DDR5 would not have been introduced if it only had a 10% advantage at best.

I'm also not for cutting edge, but DDR5 is no longer cutting edge.

I agree.

"Cutting" edge is too expensive. Those prices are always jacked up so the companies can quickly recover their investment costs of R&D, training, and retooling of their factories (so they can [hopefully] move on to the next-gen product).

So I go for "scabbed-over" edge technologies when buying new. ;)

Plus, if there are any significant bugs that sneaked past beta, they typically are found in the "cutting" edge releases. So waiting a few months or a year gives them enough time to shake those bugs out, and fix them.

Impossible to test this. Only semi wacky way I can think of is If you disabled extra e-cores and lower the CPU freq of the 13900k until it scores the same in CPU synthetic benchmarks as a 12900K. Now compare dram bandwidth with same ram. Would need to manually type in all the timings so that it doesn't auto train different ones.

It would be nice academics, but really it's the e-cores and clocks and IPC uplift that is the real difference.

If your talking about maximum frequency. Yeah it's a whole lot better. Topped out at DDR5-6933 before, now can run DDR5-8000 on the same motherboard. Granted these are both higher end speeds for the respective CPUs.

Your title says DDR4 vs DDR5, but you seem to be discussing DDR5 vs DDR5; I'm confused.

I might going for 7700x and ddr5 then instead of 13600ku cause of smart access memory. Its like 100% the same. Just 20% less multicore power but 20% less power consumption in multicore. It gives 10% more gpu power. And with 7000 they bring the feature in 2.0. i think its dope.

Smart Access Memory? You mean resizable BAR? If so, keep in mind that's also available on DDR4.

Because your not going to OC that K series chip without Z790/690 or the mortar max,asus rog b660 with ddr5 or the asrock riptide b660m.
Thats if you want to take advantage of the K chip.

I also just build a system for video edit (see my spec), no need to buy fast or low latency ddr5. Just go with 5200\4800\5600 c40 and you are fine.
Amount (at least 64gb) and stability are much more important than speed for those applications but the jump to ddr5 will give you better results all around and going to 128gb is much easier on ddr5- more low cost options.
