Quartus synthesis hardware - 2024 edition!

[foft]

I'm tempted to get a faster CPU to speed up Quartus synthesis again.

It's mostly very single core bound, with part of it improving slightly with 4-6 cores. Unfortunately no-one sells fast single (or 4-6) cores now, without including a ton of excess slower cores for parallel workloads. To get a fast single core seems I need to pay for 16 spare cores...

What I don't know is how impacted it is by:
i) Amount of cache
ii) RAM speed, latency, DDR4 vs 5
iii) Newer CPU designs such as Zen 5 and Arrow Lake

I wonder if we should try compiling a sample project to get a few stats. No-one ever benchmarks Quartus for some reason on the reviews

I'm using a 12100F with DDR4 now (super budget option) and it is noticeably better than my old 8700. I'm tempted by a reduced 14600K, or even 14900K, though the Arrow lake ones are also looking tempting. How about X3D, I know its made for gaming but the oodles of cache could help maybe?

they should definitely use it in benchmark, it's toasting my 5950x CPU everytime I fiddle with the ao486 core XD
When I upgraded from the 3900x to the 5950, I had a massive gain in Quartus, I don't know if it was IPC related or the core count but it was significant.

I currently have an I9-14900k with 64Gigs of DDR5-6400 and just compiled the Minimig core (code from repo as of this posting) and it took me 10min 33 seconds using 16 out of 24 cores.
Not sure if this is what you wanted but here is a breakdown of compile times:

I currently run an Intel 7700K (4.2GHz) with 16GB RAM, and it's much slower than most systems these days.
In particular, I'm curious about the difference between Intel's "top" and AMD's "top". (Arrow Lake looks like a disappointment).
I'll be getting a news system soon, and I'm waiting for AMD's 9800X3D to become available (that is, after release on November 7, when the dust settles and people can actually just walk into a shop and get one - perhaps January).

It would be good to have a "standard" test here, and people post their times for running that test - this way, people can see whether Intel's processor architecture (or AMD's) has a significant advantage on this code.

.... I also wonder how much impact that disk speed (or at least access time) has on it.
And after the huge improvement that all generations of AMD processors received from Windows' scheduling enhancements in a recent Windows release update, how much variance there is between Windows 10, Windows 11, and Linux on this workload.

I guess the minimig core is as good as any (I grabbed it just now as of 64cb9ce23b716a9002aaf3a144d26f71a129a8be). I compiled it with Quartus 17.0.0 on my 12100F with 32GB of 3200 DDR4 ram and an NVME SSD. Under Linux (Ubuntu 22.04.4 LTS).

So I'd get a 22.6% boost by going to 14900K with DDR5. That is quite an interesting result since purely on clock speed I'd expect 6/4.3 = ~ 40% and there were some small improvements from Alder Lake to Raptor Lake refresh.

Try putting the files on a tmpfs to cut io performance out of the equation if you have the RAM.

[foft]

Good thought.

Tried it on Windows 11 too for now (same hardware - 12100F):

A bit longer but I'd need to repeat to see if its run to run noise, or just slower.

If the E-cores are getting in your way, change the processor affinity, either through the Task Manager or using the START command to launch Quartus. You can also exclude the virtual hyperthreaded cores if you want to too. Just playing around with it on my 12700K with DDR4, excluding the E-cores does actually speed it up slightly, but disabling the virtual cores had no real effect.

These results are interesting to me. Clock speed helps, but more than 2 cores has diminishing returns, but I suspect cache size is king.

[foft]

Wow interesting result from the 12700K. With the E cores off its matching the 14900K. I wonder if the E cores are getting in the way on 14900K and it'd finish in 8-9 minutes otherwise...

I improved my RAM timings and while it made a large (~ 35 - 40%) change to memory benchmarks, it had near zero impact to Quartus compilation times.

[limi]

If only Quartus ran on an actually fast single core platform like the M4

(yes, this is a joke post, but OMG those single core numbers)
