So one of my four AMD workstations has always been a subtle problem child. I was suspicious that the CPU that I initially installed in it, a first gen Ryzen 1700X was a bad un, but I could never quite get to authoritatively prove it.
This was actually a machine I bought for my wife to use two years ago but she never wanted to use it so I have been developing my Chess AI on it quietly over the years.
I passed on the 2700X upgrade a year or so ago as the gain was not enough to swing the needle to buy but when I looked at the architecture and thermal loading of the 3700X 3rd gen, my mind was passionately made up.
Now I do not do single core work and simple computing stuff on these machines, everything is multi-core even load max amperage stuff that whacks the processor on all cores pretty much evenly to the max.
In the pursuit of the happy running of the X370 Carbon Pro mobo though, I had bought several power supplies of the exceedingly expensive variety because that system kept tripping max power on the CPU and crashing.
After the third PSU I decided it was not the PSU deficiencies causing the weird shit.
As I eyed the 7/7 date for the new 7nm 3rd Gen Ryzen 5,7 & 9 systems I had some thinking to do.
New CPU's slotting in to the current X370 gear or do I upgrade to X570 motherboards with all the other goodies as well?
I elected to go for the CPU upgrades first, slotting into the existing motherboards because this step was the cheapest route.
Also, the thermal TDP on the 3700X is listed at 65W!! That's bloody amazing!! I was drawn to this stat like a fly to shit.
I reasoned that the 1000W PSU in there now would have an easier time of it as well and it would get me a huge CPU performance leap while the pricing on X570 PCIe 4.0 goodies calmed down and got somewhat more reasonable.
It would also prove out the Motherboard vs the Processor question I had still not conclusively answered.
I also wanted to get the latest AMD 5700 GPU that was also based on 7nm technology if that worked out on the X370 Carbon Pro rig.
Right now its using an nVidia 970 and is why I will never buy anything from nVidia ever again. That GPU is total shite. I paid a lot of money for that garbage and to find out the things about that junk I have in due course has resulted in me never buying anything from nVidia, like ever again.
So today (7/13), I got the first 3700X from Amazon and after my morning shopping and usual Saturday chores were done, I nipped upstairs to install it.
It went surprisingly easy and leveraged some pleasant surprises along the way that I was not expecting.
It also proved out the fact that the 1700X I had in the Carbon Pro was in fact a bum chip.
I had to find a cloth and some rubbing alcohol to clean the thermal paste off the water cooler block.
I also painted a Hindu Swasti in thermal paste on the 3700X and screwed the water cooler clamp to it's ass.
The reason why is this shape seems to work well when the clamping of the cooler block squeezes everything every which way.
The processor is running happy as a pig in a shit bath @ 73 Degrees C.
Now this is a lot higher than the 1700X was running with the same Hi80 cooler block, but that was at a slightly boosted 3.6 Ghz.
All my AMD systems are water cooled but if this wraith thing runs at similar temps I will think about air cooling again though my home office gets hot as my wife likes lizard temps around 80 degrees F which the CPU's and I are not overly fond of....
It looks like this wraith cooler thing could lower the build cost by about $99 if you're looking to build a budget box. Its free and comes with each Ryzen 3000 series CPU.
This CPU shuts off at 95 degrees C so I have a 22 degree buffer.
The CPU cost will be $329 after the launch bollocks has died down by the way.
I had to pay $379 for mine because the guys that have em are boosting margins because they are in short supply if you must have one now.
I will wait for pricing sanity until I get the rest of em. At least I have one to play with for now.
So the surprise came when I got into downloading and installing the new Ryzen Master software on the thing after it successfully booted up.
I wanted to see what temps it was running at and what a full AI 16 thread load did to it.
You can see that at zero load it runs at 54 degrees C and at full load it runs around 73 degrees C.
But here is the surprise, this things base frequency is 3.6 Ghz and it can ramp up and self Over clock to 4.4 Ghz with ease.
As you can see here, when my Chess AI is hammering all threads to 100% it ramps up to 75 Degrees C and stays there at 4.133 Ghz.
For this particular chip this seems to be the sweet spot.
There does not seem to be anything you have to do in Ryzen master to tweak profiles etc. It does it all for you!!
Now that is very cool, I had to play around plenty the old way before I found the right settings for everything and I may have stepped over the safe OC limit on this one chip, but I did the same for the other workstation and its never had an issue.
The fact the frequency is much higher than the 1700X got to and that the temps are higher is not a surprise considering what you're getting in exchange.
I have read several folks bleating like goats that the temps are not the same as the previous gen, well the performance is not the same either!! (Idiots)..
Try not to forget the thing is overclocking from the base up to 4.4 Ghz frequency and of course at those frequencies the temps will also be higher, because its clocking higher (duh).
Actually my thermal spectrum analysis shows this chip is doing a 34% better job at cooling than the 1700X and that's not taking into account the 7nm die either!!
Fantastic job AMD folks!! Take Kudos and a mighty bow of respect from me!!
My computing tweaks just went away giving me more time to write my code and testing my product performance ranges...
