What is more important in hardware for fullstack javascript, and indeed?

Question

Iron

Hello!
I am assembling a budget workstation from junk with Ali, now I am faced with a dilemma:

• make a dual-processor station on some Xeons: many cores at an average frequency, the total cache of two processors is larger, but less per core, the total cache of one is less, 22 nm, PCIe 3.0, server DDR4 2133, but as many as eight channels (not slots)!
  
• Or the dubious Ryzen 5 3600 ($180, when similar lots are $250), 7nm - and put a Samsung 980 Pro (PCIe 4.0) SSD to it.
  

The machine is needed to study fullstack JS development, and indeed. Bribing reviews on YouTube about the performance of Xeon due to cores and channels, which sometimes excel in work tasks. But really, what should you pay attention to? Do these eight channels actually provide an advantage over two higher frequency channels? Is the maximum speed of an SSD or the speed of NVMe on the third generation of PCIe fundamental?

(I’m not considering the less dubious Ryzen yet, because the station on it already breaks ahead in terms of cost, the less new lineup is already with PCIe 3.0, with Cores it’s not at all tasty).

Answer 1

Do these eight channels actually provide an advantage over two higher frequency channels?

Maybe 10 percent will win multi-channel at equal frequencies. So at a frequency of 3000, Ryzen will clearly win in terms of memory performance.

Bribing reviews on YouTube about the performance of Xeon at the expense of cores and channels

In synthetic tests - yes. On a web server with a thousand requests per second - yes. On a terminal server with several dozen users - yes. For personal use - usually not.

many cores at medium frequency

It will be useful in case of running several virtual machines at once. Most other tasks will benefit more from fewer, faster cores.

Is the maximum speed of an SSD or the speed of NVMe on the third generation of PCIe fundamental?

Not essential. For eyes.

Answer 2

In the end, we always buy "Teraflops" and what package they are in is just the job of a marketer.
Price is the best performance indicator. That is, no matter how brightly the Cache of the 43rd level is signed, if the Ryzen 5 3600 costs $180, and the i7 3750 costs $55, then the ryzen is guaranteed to be 4 times faster.
I haven't tried BUT... I assume that for a 2 processor system you will need an OS that will support this configuration.
Next:
DDR4 2133 - server memory what does it mean? The server is just a gateway that should take it here and quickly give it there because there are 8 channels. It is not tailored for the individual user. It's like taking a Kamaz to go to the store for Bread. Will be Slow, noisy and not comfortable.
Otherwise, I had a "Netbook" with some kind of shame on board, I put 32-bit Win7 there and launched Visual Studio. It loaded slowly, but in general it was possible to use it for simple tasks.

Answer 3

According to the composition of the question, you most likely want for some reason to assemble a "mini-farm" on your knee for a test circuit of various virtual machines (web servers).
The main ambush is that it can be very noisy and difficult to maintain in terms of hardware.
What will we do if some components fail? They are not new. There is no guarantee. Right?
If you REALLY want to put that much effort into the test environment, then I would not combine a workstation for IDE, googling, reading documentation and taking courses with a test environment.
At the same time pump the DevOps skill.
As Boris writes above, some Programming Environments work fine on weak processors.
If you bother, you would do this:
1) a workstation for a development environment - preferably a dual-monitor configuration, good keyboard + mouse and comfortable chair + desk.
2) Home server for test virtual machines in a place where it does not interfere with noise.
3) Wired gigibit network between them.
