AMD Ryzen 3700X

Me too. Brought amd 3700x and 32 gb in 2020 and updated the GPU to a rx7800xt in 2024. Still no complains :cool: And yes I will have to run this rig for another couple of years...

Yeah, my Ryzen 3700x is a 3.5 year old CPU now. I might try to move to an AM5 build later this year, but it’s still a very decent PC.

I agree that Intel is bad at the moment (especially with the 13th and 14th gen self-destruct issues). But unfortunately I also know plenty of people with issues with AMD systems. And it's no bad power quality on mains as someone suggested (it's excellent here) or 'in the air' (whatever that means) if it happens very quickly after buying. I would guess that a lot of it comes from bad firmware/mainboards, etc. like the recent issue with ASRock mainboards destroying Ryzen 9000-series GPUs: https://www.techspot.com/news/108120-asrock-confirms-ryzen-9... Anyone who uses Linux and has dealt with bad ACPI bugs, etc. knows that a lot of these mainboards probably have crap firmware. I should also say that I had a Ryzen 3700X and 5900X many years back and two laptops with a Ryzen CPU and they have been awesome.

3700X's 8-cores is a generational leap above the 7700k's quad core for modern games. They aren't comparable at all. I ran a GTX 1080 and then an RTX 3080. The performance was not very good in modern games designed for current gen consoles like pretty much any BR game for example. Some games got high FPS at times but with low minimum FPS.

The 3700x and 5700x are 65W parts specifically made for quiet/cool boxes (they’re also 8 core). I have both since I enjoy my sanity and dont care about 10% extra performance. They are the pick of the litter in my mind. Also have a laptop with 5850h. Same with their Navi chips, not blazing hot but good enough, and my boxes and nice and quiet.

First off .. let me say I liked the video, it was a good overview and packed a lot of knowledge. gmp contains not only the basic operations on arbitrary precision integers, it also contains a highly efficient implementation of the fibonacci sequence. It uses a recurrence relation other than the ones mentioned, that can generate F(2 k-1) and F(2 k+1) quickly from F(k) and F(k-1): https://gmplib.org/manual/Fibonacci-Numbers-Algorithm (so in a way it's similar to the repeated squaring matrix algorithm, you find your way up to the desired number in log2(n) uses of the recurrence relation) My particular computer (AMD Ryzen 7 3700X) can compute fibonacci(21'500'000) (21 and a half million) as a 149,262,011 bit number in right around 1s. The wrapper program is not very interesting, it's literally just calling `mpz_class::fibonacci`...: https://gist.github.com/jepler/9908e9ee4a7b0becc11edbedf8b76... (I commented out the line finding the decimal length of the resulting number, but this was not actually a very big part of the runtime and could probably still have stayed under 1s.) On the same machine, OP's bin/field_ext.O3.out program takes a hair over 1 second to compute F(4 million) so it seems this algorithm, plus the probably better-optimized gmp, are well faster. However, gmp gives out soon after: It only supports numbers up to (I think; it's been a while since I figured this out) CHAR_BIT * sizeof(int) * (1 gmp: overflow in mpz type Command terminated by signal 6

I think it'll be a long time until we see an inflection point like that [1]. I also had a Ryzen 3700X, high-end CPU and case fans to make it somewhat quiet under load. Then I got the MacBook Air M1, which was as fast in multi-core use, but felt much faster in daily use to much better single thread performance (turns out that large builds spend quite some time on portions where everything blocks on one unit and the amount of parallelism is 1). And it was completely quiet (no fan). The Air M1 felt like magic at the time, I could have the power of the 3700X on the train and insanely long battery life. [1] That said, I got an M3 Pro for work and my private laptop has an M1 Pro and the difference in single-thread performance is certainly noticeable.

Right now I'm battling the rough edges around the RX 5500 XT support. If you try and use 3 monitors it reliably crashes. You can kind of make it work by manually setting monitors.xml to a low resolution on them or a low refresh rate before you add the third monitor, but that only seems to work if you add the monitor at runtime. I copied the same monitors.xml for gdm as well so no clue what during initialization seems to be crashing it only if it's during boot. I've tried all the way up to DRM-next, mesa-git, latest linux-firmware and so far I'm stuck with 2 out of 3 screens. I've also got a new 3700X and that's been completely stable.

> Or is it simply that delivering 200+W at load through a CPU socket can't be reliably done at consumer prices? It could be that the spike is the problem not the end load. The scenario in play here is going from entirely idle to maximum load in an instant. So the CPU is going to shoot straight from ~20-30w usage to 280w (or even higher if the power management is a bit sluggish at reducing the clocks). That's a pretty drastic swing if anything isn't entirely up to spec, assuming the spec even handles this properly. In theory the 3970X could even spike all the way up to 430w. The individual cores top out at 13.5w, so if they all end up running at single-core turbo frequencies even for a split second that's going to be brutal. > Anyone has had this problem with less high end CPUs? Something at 95-65 W? My 3700X in an old X370 board has been flawless. As has many others, Ryzen 5/7/9 are _widely_ recommended and have been for a while. Any systemic issues in the "regular" consumer end would have cropped up by now.
