Perpetual benchmark thread... - Page 16

The @ 4.0GHz is part of the model name when queried from the processor. It has nothing to do with the actual running processor frequency. It has confused me in the past as well.

Kieren, are you running 12 GB of RAM? Kind of an odd amount. Not having matched sticks is probably hampering performance. That being said, you're getting 32% more throughput with a 27% higher CPU clock and a 50% higher memory clock compared to my systems (for 4 cores, 1 worker, 4096K FFT). That extra memory bandwidth is helping.

Your benchmark also tells me I'm still memory constrained at 2133 with 4 cores at 3.3 GHz. I may try poking around the bios to see if there's a way to under a locked CPU besides disabling turbo.

Does it indicate 12 GB somewhere? It should be 16GB, dual channel, dual rank. They are rated at 2666MHz, running at 3200.

Yeah, it does:

Code:

 Machine#0 (total=12649168KB, Backend=Windows, hwlocVersion=1.11.6, ProcessName=prime95.exe)

I doubt it will affect Prime95 though, now that you've confirmed the install RAM.

I don't think it's the "@ 4.00 GHz" that was concerning, it was the "CPU speed: 4008.14 MHz".

That depends on the system configuration. My i7-920 system has 12GB, but it's triple-channel so 12GB is a balanced configuration. Granted most systems are dual-channel (I'm odd and my two systems are 3-channel [i7-920] and 4-channel [i7-3930K]

)

As for the RAM reported, I believe that's what's available to Prime95, not total system RAM. In my case I have 64GB installed and it logs as

Code:

Machine#0 (total=54609356KB)

which is 52GB. Although I'm not entirely sure how it pulled up that number, since I have 5 workers, specified at 11000MB each, maximum 4 high-memory workers, and an overall maximum of 44000MB. But in any case, it's clearly not the installed system RAM amount.

I see numbers like that when running stock. I think it must come from variations in the base clock.

It's not that it wasn't exactly 4000.00MHz, but rather that kladner was expecting ~4.2GHz, not ~4.0GHz, hence my suggestion to monitor the frequency in realtime.

I did try watching CPU-Z when starting the benchmark. It takes thinning out other CPU users to get a baseline. As mentioned, in the "Sync all cores" option on the Asus board seems to make the frequency (multiplier) jump around a lot. When things were quiet, and the core clock was only occasionally hitting 4200 MHz, moving the mouse of clicking on something would make it peak.

The jump to 42x seems virtually simultaneous with clicking to start the benchmark, at least to human-scaled perceptions.

I have just gotten a 7700k, and I'm in the process of overclocking it now. Will try to report back with benchmarks when I'm done.

At the moment it's looking like I'll have to accept 4.7 GHz for Prime95 runs, any higher and my temperatures get too high. Or to be more specific, at 4.7 GHz have to increase the voltage to 1.280 V to do the the Prime95 torture tests without errors, and at those voltages I get peak temperatures of 85 C, which is a bit too high for my comfort.

Mark Rose · 2017-04-17, 15:50

Do remember that Haswell and later bump the VCore +0.1 when doing AVX2/FMA3 (which Prime95 will use).

The current Core architecture has been around for 6-7 years and has lots of time for software optimisations to be done for it. Ryzen has been out for 1 month... I remember back in the v26.xx days, Prime95 was a lot slower before optimisation.

My Ryzen is mainly working on World Community Grid projects (generally not highly optimised code). There I see a 2.5x the points per day compared to my 2600K @ stock clockspeeds. At the same clockspeed, the IPC is around Haswell level and it has double the number of cores.

So for the case of both systems running on 8 physical cores, it's 7.136ms for the i7-6950X @ 3.0GHz vs 12.69ms for the Ryzen 1700 @ 3.3GHz. Looks like Intel wins big in terms of IPC.

Would still be interesting to see the results from a i7-7700K (half the cores, but higher IPC and higher clockspeed)... to compare at a similar cost level (a Ryzen 1700 system being still a bit cheaper than a comparable i7-7700K system).

Here are my results

Hardware:
CPU: i7-7700K - at 4.9 GHz with AVX Core Ratio Negative Offset of 2 (which reduces the multiplier to 47 when running Prime95, giving a clock speed of 4.7 GHz)
CPU Cooler: Noctua NH-D15
Motherboard: ASUS TUF Z270 Mark 1 - BIOS version 0906
PSU: EVGA SuperNOVA 550 G3

If there ever were a case for more memory bandwidth...

It's nice to see a 4 core with over 200 iter/ms at 4096K FFT though!

I think you have an extra 'm' in there. Maybe with the magical optical computers (using yellow of course) we will see 200 iter/ms. But as of today, I think not.

With new data at hand, we could do some more comparisons.

The 8192K FFT performance looks incredible on this version of Prime95, especially when all 8 cores are thrown at it. Would be good if someone can post results from a similarly priced Intel i7 7700K on Prime95 v29.1 Build 15 for comparison (I expect the i7 is a lot faster per core, but at the end of the day having double the cores may make it a rather close competition).

It seems, memory plays an important role. I got 30% lower times with the new beta BIOS, 3200-14-14-14-36 DR, and running at 3.5GHz (stock CPB):

Code:

From my Ryzen 7 result:

Best time for 8192K FFT length: 9.107 ms., avg: 9.352 ms.

Normalized to 3GHz this would be 10.625 ms, or 67% the speed of your result. That's the penalty for half the AVX + cache throughput and mem channels.

Timings look good!

If you want to save a little power, you can go into your BIOS and tweak the 4-core Turbo speed and lower it to 3.6 GHz. You should still get almost the same throughput. That way if you're running mprime the power usage and heat will be lower, but when running anything that doesn't use all four 4 cores it will get the full turbo speed.

I had a battle on my hands for a while. It was pulling 350 watts into the PSU. CPU cores running above 90°C. It was blowing hot air like a furnace. This was with Prime95 only!

I've made several trips back into the BIOS since. I loaded the default settings and everything started running much cooler. The power pull now is 142 watts and core temps are running in the low to mid 60's. Again, with Prime95 only, running a P-1. I don't know what settings the BIOS originally had. The first time I powered up, I just sat here and looked at it for a while. There is a lot in there.

The CPU is hovering between 3.96 and 4.02 GHz. However, and this is something I will probably need to put in the Prime95 area. It's only using four, of the eight, threads available, and will not allow me to use more than one worker. Curious!

That's working as expected. The CPU can't hit the top turbo speed when using all four cores. Also, Prime95 is so efficiently coded that using hyperthreads (which is basically two threads taking turns on the core) doesn't speed things up.

With regards to only one worker, I believe it will force that if you're working on very large exponents.

I'm probably going to disable turbo-boost as it looks like it is pretty much memory bottle-necked (going from 3 to 4 cores only adds 30 iters/sec.

Also flies on this mobo with this RAM. Getting 3.75ms for a 2^80,000,000-1 LL test, which is amazing considering it consumes 1/2 the power of my 7820X which iterates a similar test at 2.8ms per iteration.

Here are some interesting comparisons. I ran benchmarks for 5760K FFT, on a 6700K CPU at 4400, 4200, and 4000 MHz. 32 GiB dual rank DDR4-3000 RAM. By narrow margins 4200 MHz came out best, but all three sets top out within a few it/sec of each other.

4400 was the first run. After that, I dropped the 4-core-1-worker test because 2 workers were coming out better.

Could you do it on range of FFTs (e.g. 2048 to 8192), and without testing all implementations?

Thank you. I've looked at the results, and it seems like there is little advantage from RAM speed with those speeds and that CPU. And for some reason, the 4000 turns out fastest on some FFT lengths, but it is not that much so it may be a measurement error (some background tasks).

Is it possible that when RAM is faster than CPU clock, it will not be used the same as with faster CPU? I'm thinking about this exact thing, because I have 3200 MHz RAM now, and I want to know whether I should buy 4000 MHz or 4400 MHz RAM because my CPU is manually overclocked to 4,1 GHz (Ryzen 9 3900X).

Note the massive L3 cache on that chip. It is not surprising that RAM speed is not a factor.

L3 is 8MB on a 6700K, which is mediocre.

Ok, makes sense. That still leaves the question of why mem speed is not affecting performance. I suppose, with just 4 cores, all of the tested RAM speeds are sufficient to feed the CPU.

Ryzen L3 are all power-of-2, but since it is a victim cache, AMD specs list L2+L3 as a single "cache" number. So if you see 70MB for a processor, that is 64MB L3 + 6MB (12*512KB) L2.

I have to note that the RAM speed was the same in all these runs. Only the CPU clock was different. I took the very similar results as an indication that this system is memory-bound.
EDIT: Also, these tests were not run under strict lab-like conditions. I did shut down obvious cycle-stealing apps like performance monitors and browsers. In line with normal operation on the machine I deliberately left mfaktc running on the GPU as part of the environment. Allowance has to be made for margin-of-error.

Mark Rose "/X\(‘-‘)/X\" Jan 2013 2×5×293 Posts	The @ 4.0GHz is part of the model name when queried from the processor. It has nothing to do with the actual running processor frequency. It has confused me in the past as well. Kieren, are you running 12 GB of RAM? Kind of an odd amount. Not having matched sticks is probably hampering performance. That being said, you're getting 32% more throughput with a 27% higher CPU clock and a 50% higher memory clock compared to my systems (for 4 cores, 1 worker, 4096K FFT). That extra memory bandwidth is helping. Your benchmark also tells me I'm still memory constrained at 2133 with 4 cores at 3.3 GHz. I may try poking around the bios to see if there's a way to under a locked CPU besides disabling turbo.
