How Low Can You Go? Memory Latency Competition - AIDA64

Intel is apparently lightyears ahead of AMD in terms of memory latency.
The infinity fabric is still relatively new tech, it doesnt prove a thing other than it is lower latency.
 
One interesting pattern to note when looking at our leaderboard is that Intel is apparently lightyears ahead of AMD in terms of memory latency. Matter of fact, the best Ryzen rig in the comp has roughly TWICE the latency of the best Intel system (32.8 ns)

Not sure if this is going to have a noticeable impact on real world performance, but what exactly is the deal here?

It's odd that I can pull 49 ns on my dated Phenom II rig, yet it still has a -10 ns advantage on the best Ryzen chip in the comp. Granted, I do have the memory controller overclocked to 3.0GHz, but still, you'd think the latest Ryzen chips should be able to compete with Intel in latencies.
Yeah, sadly my Ryzen 7 3700x rig with mid tier (c16 Hynix DJR) RAM can't get anywhere close to those Intel Latency numbers.
But that being said, my 3700x performs extremely well in everyday use (streaming, video encoding, web browsing all at the same time).
So, while I do wish the RAM Latency was on par with the Intel rigs, I'm still happy with my rigs overall performance.

so this is interesting... i just bumped it to 5.1ghz for kicks, and it's actually passing a stability test (where before it wouldn't even start, this is a 3 year old rig) I wonder if the mitigations for spectre/meltdown changed the rules for cache.

Interesting indeed... How did it go? Are you still running at 5.1GHz? Stable?

Phanbuey gets the combativity award for the day for this OC and latency improvement.

@Arctucas has both the green jersey (points) and retains his position as the overall leader of the competition at this moment. That low 30s number is going to be hard to beat!

@DR4G00N You have anything that can go toe to toe with this kind of blistering speed?

It failed unfortunately... I went back down to 4.8 - but it took a while to fail where it would die pretty instantly at 5.1 before on the same AIDA cache stress test.

Thanks for your submission. We now have you added to the leaderboards.

To be honest I am a little surprised at such a wide variety of memory we are seeing with these submissions. Goes to show you, we have a lot of first world options when it comes to choosing our system components :)

Remember the days of the 3.3 volt unbuffered SDRAM? Just look at how far we have come in 20 years! DDR4 4500 and beyond! Who would have thought?

Do you add only one best result or several if there are results from different systems?

Hey, Storm-chaser, i've just found a little mistake in your leaderboard spreadsheet: my timings is actually 16-18-18-36, not 16-18-19-36. Please, correct this hilarious iniquity. :)

So, multiple rigs are allowed and we will take the best result from each system.

Okay, we should be current with the leaderboards now. My vision is not so great (yeah, I actually should get glasses) so if I make a mistake please let me know and I will go back and fix it.

I split each leaderboard into two parts to keep the font readable (I didn't want to zoom out and further shrink the text)

By the way, whoever wins the overall title will get an AMD 965 Black Edition (if you want it). This is an unlocked X4 3.4GHz chip (RB-C3 Deneb core) that easily overclocks to 4.1GHz with a decent mainboard.
 
Just went and put a run in to kill some time. Got this kit of mems last week.
Didn't feel like fighting with my 8700K & MOCF for 4200+ 12-11 today and this was already on the bench.

CL 8 @ for the win. Sounds like you made a good call with the new memory.

Those are great numbers for a DDR3 kit.

*Leaderboards Updated*

Also will there be another table to keep track of all submissions; maybe hidden behind a spoiler?

Sam - I think for now we will just go with your best submission to keep the emphasis on performance. Easier to keep track of the results that way.

I am hoping to come up with some other benchmarks that can be charted in similar fashion to what we are doing here. I am primarily interested in quick benchmarks that give us good data sets, preferably free ones that everyone can get in on, regardless of rig performance. I prefer to keep the emphasis on CPU and/or memory, not necessarily GPU performance.

We are adding only the single best result per rig. So yes, all your systems will get a place on the leaderboard provided they have dissimilar hardware.

Good news friends. My new CPU has arrived...

Barring any delays or hang-ups, I am hopeful that by midnight tomorrow I will have results of my own Coffee Lake S system to share with you guys.

I purchased this G.Skill kit to go with my hexacore 9600KF:

16GB G.SKILL TridentZ Series 16GB F4-4000C18D-16GTZ (NON RGB, I will NEVER go RGB)

These are 4000MHz modules.


This will be my first overclock on the Z390 platform. I'm chomping at the bit!!!

….get it? lol

:toast:

ps. Based on the data set from this benchmark I am going to set my first goal at a modest 40.0 ns and work down from there...

I think that you will not have any problems to overcome the 40 delay:toast:

And about my first result on Corsair memory. There, even by marking, you can understand that the volume of the kit has 2x8Gb. So you can safely add this information :)

Looking good!

Close race going on for the top spots. This could get interesting...

Something got messed up in the Memory Latency Leaderboard. Im in last spot...should be around 20th, i think...

I forgot to sort it after adding your entry. I will get it fixed this morning.
 
My RAM config is 4x4GB Vengence Pro from Corsair - not the HyperX listed in the charts. :P

Also, there appears to be an issue with the order of the charts as I'm below the 48.Xns listing.
 
well, thought it would be better but....

One possible explanation for the lackluster performance… your north bridge clock seems a little low... AFAIK you should be able to push that well over 4500MHz with decent cooling.

Also, how much and what model memory are you running?

So I just made a number of changes to both leaderboards... I hope I didn't screw this up. We want concise information here so please take a moment to review them again and let me know if there are any remaining issues.
