New PC

Postby Julio Jerez » Mon Aug 17, 2020 10:47 am

Hi guys, it has been a while.
Since by pc got boosted, I was thinking to get a new one, the very few times I bough a PC I have someone at some retail assembling it for me, but now retail stores aren't selling parts on site, so it has to be ordered by mail.

when I check the places that sale complete systems, they it seems they expect a high profit which I do not blame them for, but when you are the one paying, it give you pause.

must places have three categorizies:
low budged, under 1000
Main Stream, under 2000
and enthusiastic, under 3000

Some places have high ends work stations that the say are for video editing and content creation but those goes for 4000 and much higher, I saw a place that have a ridiculous 35,000 dollars pc.

anyway the thing is that when I check the enthusiastic range of PC, they do not even have high end CPUs, they come with 8 cores, and the part aren't even as good as you expect for that price, It seems all they do is stock an expensive 1200 dollar Nvidia GPU, and the rest are mediocre pc parts.

any way, I decided to try put the parts together and this is what I got. I have always been an Intel guy, I still believe Intel architecture is better than AMD, but the reality is that more cores trump faster clock rates and better architecture. Intel fell sleep at the helm they do not get their act together soon, they will lose to AMD and ARM.
Anyway here is what I came up with. What do you guys think of a system like this. my bigger fear is that the parts do not work together once I order it, the second fear is that second I order it, Intel come out with the 7 nm 16 cores, icore10 like it always seems to be the case. Anyway here is my selection.

the system is a little over the budget I was planning $2600.00
I was planning $2500 but when I checked for system with similar configuration they seem to be over a
$1000 higher in price. with a lesser CPU, amd 3900x instead of 3950x.

The video card and a good motherboard + latest cpu is very expensive.
The picture don't show all parts but all parts look compatible and ok.
I very love asus motherboards they have very nice quality and features.
The 570 is a good one.
It is around the same price here in Canada with the taxes.

Don't forget to get a water cooling for your amd cpu.
If you use a fan heater you are at risk to get very high temp when all cores and threads is in use at full speed.
I suggesting to use silver thermal compound, I use this one here: https://www.newegg.ca/arctic-silver-as5-3-5g/p/N82E16835100007
The silver thermal compound don't become dried with times like the white version.
The silver give better result too.

so you think liquid cooling is better that air?
I saw some youtube videos where the compare liquid vs air, and some people say that Air are almost as good. but that the benefit of air si that the are more safe.

they said that liquid build up crust, and can even leak. I guess we know need to treat compute lie cars with radiators, that the need a tune up or oil change and check the liquid every few month.

you are right I will change the cooler for a liquid one.

one thong I do not understand is what is the difference between a ryzen 3950x of a thread ripper
the both have 16 cores 32 thread. and on paper the 3950x seem better yet cost a lot less.
I do not get it.

I'm not sure to understand the 3950x don't have threadripper version.
https://cpu.userbenchmark.com/Compare/A ... 9111vs4057

https://cpu.userbenchmark.com/Compare/A ... 4057vs4044

Some fan heater can do the job but at high cpu use the watercooling is the best and it do less noise too.
Here I use corsair water system, maybe some models is better but I never have get problem.
I have two corsair one is very old and I never have change liquid and it never leaking.
The only thing that I change all year is my thermal compound.
It is not always a obligation to change the thermal compound all year but it help a lot. Here the summer is very hot I prefered to don't take risk with it.

My ryzen 2700x can't handle bench mark or unreal engine compilation with the original fan heater in summer.
With the water cooling it is stable and it don't go at danger temp.
My friend have the 3950x and he have very nice result in the benchmark. It is around 3 times faster that my ryzen 2700x in multithreads.

I can get a bit better with my 2700x but I need to set the full turbo clock.

Hi Julio,

nice to hear from you. The pc constellation is amazing :) With this one you are up to date for a few years.

I did not know that window 10 is that expensive. Its also possible to buy a windows 10 key for 5 euros.

Best Regards

I changed the cooling form air to liquid, that add another 100 so the price is now 2750, which I think is fair, so I click check out to place the order. but when I do that, they come up with the false advertisement *.

they show the part the do not have, but they are not showing it when you are selecting them.
Instead they try to offer a different selection without cpu and power supply. missing 4 out of 12 items.

if I did not check the selection I send the order and I get screwed, I can imagine how many people they get hooked that way.
as much as I hate it I am going to have to order from Amazon. They do not do false advertisement.

it seems the amd 3950x at this time is vaporware.

My friend have get one from amazon without trouble.
Here in Canada I can get one without trouble too:
https://cipc.com/details/amd-ryzen-9-39 ... -processor
Maybe some stores prefered to have it only online because of the price.
If they don't sell it or if the price become lower they don't lose money.

Yes Amazon appear to have it but they ask almost $150 more than the listen price.

The mail order stores now are making a mockery of the consumer, and I do not want to take by business to Amazon.

I try to go to newEgg again and they show a cleaner list that exclude what they do not have.
I will try to build around an amd 3900x
That 12 cores, and should be more than adecuate to dev the engine.

I was thinking to start Newton 4
But this time with a new c++ interface and cleaner API.
One that is more c++ 11

C++ 11 has many nice facture that makes it possible to write cross platform code more essay.

Personally I only have the 2700x and i'm very happy.
The speed difference between the 3900x and the 3950x look very low.
https://cpu.userbenchmark.com/Compare/AMD-Ryzen-9-3950X-vs-AMD-Ryzen-9-3900X/4057vs4044
With very little speed difference and lower price the 3900x look like a very good choice.

My brother have get the ryzen 5 3600x it is a very good choice too vs speed and price.
The 3600x is a bit faster that my 2700x in single core, In multithreads the 2700x is a bit faster because it have 2 more cores + 4 more threads at full cpu clock.

https://cpu.userbenchmark.com/Compare/AMD-Ryzen-9-3900X-vs-AMD-Ryzen-5-3600X/4044vs4041
https://cpu.userbenchmark.com/Compare/AMD-Ryzen-9-3950X-vs-AMD-Ryzen-5-3600X/4057vs4041

My ryzen 7 2700x is older and the ryzen 5 3600x is a bit newer.

One good thing you have choice a good motherboard, It is always possible to change only the cpu later.

About Newton 4 it is a very good news.
I'm always ready for testing. :mrgreen:

I'm a big fan of C++ so that sounds good although I am managing well with the current setup. Always good to hear of progress.

As for as PC I normally go for the card/cpu etc that is the one before the latest and greatest. You get a nice price drop and often the performance is very good.

I will make two root directories in the git deepot
Newton 3.24
Newton 4.00

Them I will start adding the core libraries little by little
This time there will be not tow libs, one with prefix d and one with prefix DG
Now it will all be d.
So there will be only one set of libs that will all be C++ 11 compliance.
This means old compilers like vs 13 are not longer supported.
Newton core is already c++, so the conversion should not be too hard.

Will the C-interface / dll system remain in use?

no, if we need a c interface we can use something like swigg that can create automatic conversion.

as soon as I get the base skeleton, I will try to set up the swigg script and see how that goes.

Water cooling is only if you want to overclock your CPU. The CPU is designed to run normally with air cooling. I would not mess with having a bunch of liquid in your machine. It would seriously be safer to submerge the whole thing in a vat of vegetable oil.
