I have a 5700X3D laying around. Should I finally get around to installing it? Or should I sell it? I have a 3600 installed.

Be careful with these older boards. Some might be PCIe 3.0 making your GPU and NVMe dog slow.

PCIe 3.0 x16 is enough for up to a ~5080, you only lose single digit percent fps.

Definetly not dog slow as long as your gpu is x16.

Even like 2016 vintage boards were PCIe 4.0 so I don’t think this is a huge issue?

The article mentions AM4 boards and many of those are PCIe 3.0.

Chipset PCIe Version Supported
X570 PCIe 4.0 (both GPU/NVMe)
B550 PCIe 4.0 (GPU/NVMe; other lanes are PCIe 3.0)
A520 PCIe 3.0
X470 PCIe 3.0
B450 PCIe 3.0
X370 PCIe 3.0
B350 PCIe 3.0
A320 PCIe 3.0Hikikomori
Doesn't matter for gaming at least.

NVIDIA models 4060/5050/5060 have only 8 PCIe lanes. Combine that with PCIe 3.0 and it becomes a problem.

Rocking my 5800x from 2022, 32gb ram.

The people that predicted this face a dilemma. They were ridiculed when their forecast was against popular opinion and now they are ostracized because they were right. I've seen this happen to many researchers in AI and it's demoralizing.

oh ffs, I was just thinking about upgrading my current PC with a new GPU and CPU and just keeping the same 64gb of AM4 DDR4 I already have. But now even the prices for the CPUs are skyrocketting? Eff everything about this and curse Sam Altman.

BS. A used (not available new) 5800X3D is 350€, while a new 9800X3D is around 460€.

I think its the memory price checked and 32gb of ddr4 is a 170 eur while same size kit in ddr5 is over 400 now. If you want to build a cheap 1080p 1440p gaming desktop it all adds up.
PeterStuer
The article claims "Second-hand prices for the 5800X3D average around $500-$600 on eBay. Some of the highest-selling units sold at nearly $800, showing how desperate some buyers are to buy AMD's best gaming chip that still uses DDR4 memory"
This is absurd. "Average quoted" on ebay does not mean anything, neither dors their claim of "highest selling" which is "highest listed". Nobody is buying at these prices.
People buy the lowest priced (incl. Shipping) with modifiers for professional>private, seller review rating, location and picture/description quality.

base speed 32gb ddr 5 ram goes for around 800€, aka 4800 MT.

Based on the benchmarks that I've seen, 5800X3D is still a good CPU for games, when paired with a very expensive GPU, otherwise a 5600X is cheaper and acts less than a heater over the winter. Someone with the money for a nVidia 5800 GPU will pair it with a 9800X3D, for most games even 16 GB of RAM will work and would be cheap enough, while for applications one does not need X3D, so what exactly is the point of 5800X3D scalping?
tetraodonpuffer
5800x3d / 5700x3d are MUCH MUCH MUCH faster than non-x3d in some games that are CPU bound (for some even 2x / 3x faster than non-x3d) so even with a "slower" GPU it can still be a large upgrade
Asmod4n
when you game in 4K thats only relevant for games like factorio or city skylines.

It’s impossible to keep my 5800x below 90C under full load.
Asmod4n
Mine runs at 60C when running Prime95 at full load, i got a open bench case though.
The 7000 series is designed to hit those loads, i wonder how your 5000 series can even reach that.

The Ryzen CPUs seem to be designed to spike as high as whatever thermal limit you configure with Precision Boost Overdrive.

This is where the 5700X shines. 8 cores, still cool.
wtallis
The 5700X has the same 8 cores as a 5800X3D but with a slightly higher maximum clock speed (the X3D CPUs tend to have lower maximum voltages because the extra cache die doesn't tolerate voltages as high as the CPU cores do). The only reason the 5700X is running cooler for you is because it comes with a 65W "TDP" setting out of the box rather than the 105W "TDP" setting used by the 5800X3D. If you configure a 5800X3D to operate at the same power limit, it'll give you generally better performance than a 5700X.
In general, buying a power-limited desktop CPU has never been a good strategy to get better efficiency. You can always configure the full-power chip to only use that extra headroom for short bursts, and to throttle down to what you consider acceptable for sustained workloads.

And the 7900 ! (AM5 though)

> so what exactly is the point of 5800X3D scalping
in the past, growth in PC gaming came naturally with the growth in the adoption of computers around the world.
at saturation of "new to computers" audiences, growth in PC gaming comes from convincing the core gaming demographic, newly-turned 13 year old boys, to agitate for PCs instead of XYZ.
so a big part of it is the retail-marketing experience - the aesthetics of buying - and scalping / sense of urgency plays extremely well with the buyer who actually chooses PC over a nintendo switch, as opposed to a kid who will never make the more expensive choice ever.
this is really a story about saturation than it is about hardware or shortages for AI usage or whatever.
Upgraded my 2400G to a 5700G with new 64GB RAM a while back, which is really the end of the road for my system. I got a solid 3x performance increase on multi-threaded apps. Also have enough RAM to play with some this AI stuff - yes even on an AMD APU. Next purchase will likely be Zen 7.
