What went so right with Ryzen and AM4?

It's mind boggling that someone who may have bought an AM4 motherboard in 2017 can get a 5800X3D and have a great CPU

cpu tech is in stagnant state

>what went right
Russians sabotaged intel

2bh with stacked caching they dared to throw more silicon at the problem in a new way and was working on it for years there are TSVs for that purpose on the earliest Zen 2 chips even
They took a risk laying out their chips with the in mind even though it wasn't apparently ready until 2021 and so won two small but worthwhile markets with x3d and milanx

>can get a 5800X3D
You mean get it from questionable chinese sources for the same price as a brand new 7800X3D? nah i'll just wait for the 9800X3D or the next generation to be affordable and turn my current machine into a dedicated HTPC.

t. non-3D 5800X enjoyer

I bought into AM4 in 2019 and still find it hard to justify replacing my 3700x.

What happened is that software has been slowly bloating up over the years in line with ever increasing CPU performance, but now that everything's just running inside a web browser one way or another, we've hit a peak in terms of potential bloat.
Since software is having trouble getting slower, there's less of a need for CPUs to get faster, leading to stagnation so your old CPU is useful for far longer than ever before.

I am absolutely flabbergasted that Intel hasn't done the same yet.
They wouldn't even have to stack it the same as AMD, just dump another fat wad of cache into the chip.

>>106365524
Well, now that they're not in high production, that's true.
There were times you could get it much cheaper, or the 5700X3D, or even the 5600X3D, but AMD is stopping producing them.
But the chips still perform really fucking well today.

AM4 is arguably when everything went to shit.

>>106367491
Investing into what is essentially a legacy platform seems like a moot point, but if you can get them 2nd hand and or at bargain pricing sure they are quite nice to have.

Fortunately or unfortunately everybody in this country is so dumbly intel brained thus making Ryzen's are much rarer but also decently priced on 2nd hand websites. I can go and grab a Zen 4 processor for 100$ or less, or alternatively a whole rig with a Zen 3/4 and lower end GPU for 400~

>>106367480
It has, much earlier than AMD in fact

1. external cache/multi chip designs were common in the 1980s 1990s
2. it doesn't even have a silicon interposer like HBM (developed by Korean companies alongside AMD) so the bandwidth and energy efficiency is limited.
3. even worse, it doesn't even uses TSV and intra-chip bus, between that and 2. that crap can't scale up.

There's a reason why nobody considers side-by-side chips using normal PCB as a real chip integration. At least use ceramics MCM, but if you're serious you would use HBM like AMD/Nvidia or TSV.

Except for AMD and its entire server lineup, apparently

>>106367896
Which severely restricts the inter-CCX performance and the IO chiplet is closer to a NB than a well connected chip like it's done with interposers. Without mention the energy penalty, IF represents 15-30% of the total energy consumption.
AMD's chiplet design has its trade offs but in exchange it allows better flexibility and a unique CCX design. 3D Cache favored Zen so much for that very reason and Zen was designed around a looser integration than things like Intel Core using ring bus or mesh-ring bus.

The 5800x bottleneck the rtx4090 hard.

>>106367515
Why?

>>106368943
he bought intel shares

>>106365490
I've upgraded from 2600 to 7500f and the only thing that seems to have changed is they made the components run hotter (CPU, SSD, RAM). That's it. My suspicion is it's a corporate strategy to put more thermal strain on components so they have shorter life expectancy and as a result will have shorter replacement cycle which means more sales.

Am5 is not bad but it does run hot compared to intel, I know amd has always run hot compared to intel, this 9700x is the first amd cpu I've bought, it idles at 45-50, maybe it's because it's in a sff case but intel is definitely easier to cool

>>106368992
They added a mesh of temperature sensors and current readings are far more accurate than (~) pre 2015 temps. That's the only difference, none of those readings are the hotspots of the cpus and except for shintel destroying their i7/i9 current CPUs are reliable.
