Do Dual CPU Sockets Matter in 2018?


Xeon W Xeon scalable You know They’re both called Xeon But these things are really different One of them is basically a Core i9 with ECC memory support And the other one is a server CPU that I fangirl all over Because I love super high-end expensive tech toys Now, in the past You needed multiple CPU’s in one multi socketed motherboard in order to handle intensive multi-threaded workloads But, is that still the case today? Do you still need 2 of these, given that a single Xeon Platinum 8180 is 28 cores and 56 threads on a single chip. I don’t know What is the purpose today of A dual socket machine like this one and how much have single high core count CPUs? Eroded the market that they used to enjoy Let’s find out. Shall we? After I tell you About today’s sponsor Mack Weldon Mack Weldon makes great underwear t-shirts socks wallets and more they believe in simple shopping and if you use code “TECHTIPS” You will get 20% off at the link below Alright there’s a lot more room down here and we are gonna need it for this honking, not to mention heavy test bench. On this test bench, You will find the Asus C621E Sage This is a dual socket motherboard, rocking 2 LGA 3647 sockets for Intel’s Xeon scalable lineup of CPU’s And setups like this have actually been around as far back as the 486 in 1989 With the resulting second-hand hardware giving enthusiasts the ability to get multiple physical cores in their homes over the years with the peak being somewhere in the mid 2000s or so But, that was then and this is now Now you can get multiple processing cores in a single chip To see how far things have come what we’re gonna do is pit this machine against the fastest Single CPU that we’ve tested to date We’re gonna try to keep the number of variables to a minimum in order to gauge the impact That these extra CPU cores will have on our setup Though it should be noted that there aren’t many options when it comes to aftermarket LGA 3647 coolers because most of the folks selling these kinds of systems would figure out their own solution So that means that our dual socket workstation will run a little bit toasty But we didn’t observe any thermal throttling so it shouldn’t affect our performance Let’s start off then with good old-fashioned Cinebench I mean, we’ve seen this run before but it’s always fun to see it finish that quickly So, in a surprise to no one the dual socket machine is faster but considering it’s 56 processing cores not all of our workloads scale in the way that we might expect 7-zip for example, shows a smaller than expected gain over our Core i9 Extreme Edition Y-Cruncher even finds itself losing ground Asus real bench demonstrates this though with that said the encoding benchmark eats out a lead over our Core i9 7980XE and then Blender, well here we actually get a victory for our dual CPU system again Showing this platform’s potential for expanding render farms but What is really going on here Well, something you guys have to realize is that there is more to a dual socket configuration than just more cores Do you remember when AMD managed a three percent improvement in IPC with 2nd Gen Ryzen just by improving cache latency? So on this motherboard, we’ve got two separate CPU’s with two separate sets of cache and memory See, these 6 banks go to this one and these 6 banks are wired into this one and that means a lot of latency for compute tasks that require the same data sets This latency is a necessary evil in the design of multiprocessor systems because of the need for Non-Uniform Memory Access (NUMA) for short That allows these two processors to efficiently share resources or as efficiently as they can So the short version of this is that it works by transparently allocating devices and memory to each CPU which means they can more easily avoid interrupting each other while accessing those resources This in turn reduces the amount of waiting around that they have to do for those resources to become available So, that’s what we’re seeing during our testing like in Y-Cruncher for example… Where both CPU’s are working on the same data, but… *babbling* What if we could use different data sets Then we should be able to find this kind of setups true calling and how better to do that Than to effectively turn this system into two independent computing machines using virtualization So let’s fire up unRAID, which uses Red Hat KVM as a hypervisor to see what kind of results we get splitting these resources into multiple independent machines Immediately, we see worse results from our VM’s than our original 56 Core testing But, look closely[er] at how much lower it is It’s not a whole lot In every test, it’s basically the same story here and we are still Wwwaay out ahead of the Core i9 Extreme Edition, particularly when it comes to Blender Now if we consider the fact that we are getting simultaneous work done That gives us a good look at what an optimized workload might look like I mean or heck Virtualization itself is a legitimate task to, I mean this thing Could be so many gamers in one PC ( ͡° ͜ʖ ͡°) but I digress I mean nobody is gonna buy something like this for their personal rig anytime soon given the $10,000 per CPU price tag which puts it squarely in the territory of “big the size of the check doesn’t matter” business What they care about is density The more processing power, a single computer can manage, the more processing power that can be physically fit into a building and this is perhaps most important for data centers and render farms in particular The less those guys have to spend on setting up the electricity and cooling management for a data center Versus the amount of performance they can get the better soooooo Will multiple sockets make a comeback in the prosumer space? Outside of you know oil and gas exploration where there are still workloads that can benefit from this kind of thing the chances look pretty slim if you ask me But I don’t necessarily think that it’s Intel’s intent to sell these chips in the prosumer space and for that matter Even in the enterprise space. I don’t think they knew a ton of them For me, I look at a product like this as more of like a future crafting exercise where it is available today, but it’s more of a representation of what actually might be attainable a generation or two from now Just like the 22 core processors that we were playing around with a couple of years ago Nowadays, those are much more affordable and businesses are using them to power your cloud computing services It’s making of services Dollar Shave Club is the service that has all of your grooming needs taken care of They’ve got toothpaste body wash, hair styling products, everything You need to look feel and smell your best and they’re basically Giving away their daily essential starter set to new members for just 5 bucks In the first box, you’ll get their shave butter their body wash and their one wipe Charlies butt wipes and you’ll also receive their executive razor which includes their premium weighty handle and a full cassette of cartridges After the first box, replacement cartridges are sent to you for just a few bucks a month So check it out today at dollarshaveclub.com/linus.

  1. the biggest consumer for set ups like this is of course porn hub to render all those quality family friendly home videos to the streamers ;).

  2. it would be a lot more fun to look at with an OS that can schedule these resources in NUMA better than Windows 🙂

  3. Not enough bang per watt for me but I don't like seeing old tech go to waste. But then using old tech can be a waste of lecky compared to new efficient tech…

    I like the idea of a chip/PCB stack system with vertical bus and side connectors… 1mm tall pins top and bottom, side pins can be a bit longer for secure connection of peripheral chips/boards… simple direct pin to pin connection with optional female-female riser for extra space for cooling. A box frame fits round it to secure chips in place while still allowing access to side pins… CPU, APU/GPU, memory, SSD all on the vertical bus. A few square standardised sizes, 16×16 pin 35mm x 35mm, 32×32 pin 70mm x 70mm… pins can be switched off and double as a heat sink. Can be mounted sideways for better heat convection in non-thin devices. Multiple socket mobos wired into the vertical bus with pins matching the vertical stack peripheral side pin layout.

  4. LINUS TATTOO.. totally in sync with his jesus sandals and white socks. haaaahaaaa. a 20 dollar tat looks wac linus..you need at least the size of a 1080 of said skin area filled in.

  5. Processors like the 8180 have a place in the enterprise, but it's not in virtualisation and render farms. Processors like this are used in specialised compute tasks where it threads well, but needs very high bandwidth between individual cores and sockets, such as some application and database servers. Density is important, but processors like this are simply too expensive for more mundane enterprise tasks, like virtualisation, render farms, big data and web servers, where you can find a sweet spot between power density and unit cost, and just throw more physical servers at the problem. Even when you're looking at more middle of the road processors, at around 12 cores per socket, 2 sockets per blade and 16 blades per 7U chassis, that's a whole lot of processing in a rather small box.

  6. I've got a dual socket G34 running a total of 24 threads. It's a fun toy that does a few specific tasks quite well. (Other workloads – "not so much…") The boards are about a hundred USD, the CPUs ten bucks a pop, and memory is just a touch over 1 dollar per gigabyte. 🙂

  7. obviously the point would be the cost its cheaper to have more than 1 older/cheaper cpu which is a much better option than 1 more expensive cpu multi socket motherboards are reasonably cheap plus the compatible cpus is significant in cost/performance ratio and the extra cost can be diverted to the gpu preferably more than one keep in mind that im 19 and only makes like 90 per week

  8. A few years back, I built a dual core Opteron setup, and by the time I finished it and got it up and running, I could get the CPUs for a fraction of the price, and so I decided to bugger it and go Quad.
    I now run a 64 core Opteron based Server, that was by far the biggest and most expensive pile of junk that I have EVER done.
    What is even more rotten, is that for a giggle, I setup an old P4 2.6Ghz Single core PC that did the very same job as the Opteron does… Why did I need so much power to essentially serve my house Movies and MP3s?

  9. Eventually you hit a brick wall in core count due to both the thermals and later on cpu density.

    At that point the industry has to return to multiple cpus. He’ll even now with 10nm intel is drastically reducing clock speed.

  10. Another reason for use this kind of setup, Full 4 Way SLI. I need a system to support 4 GPU in full SLI. No Single CPU (AMD or Intel) had so many SLI lane available for GPU. Closest was AMD threadripper with 64 SLI lanes but all are not available for GPU (some needed for communication and 4 for NVMe drive). I got the same motherboard but with Xeon Silver Scalable 4110 for a total of 89 SLI lanes (48+48)

  11. Almost all of my systems are dual socket systems where/when possible.

    It's FARRR cheaper for me to buy even a first gen Xeon E5 (dual E5-2690, 8-cores, 2.9 GHz base, 3.3 GHz all cores turbo, 3.6 GHz max turbo) than it would be for me to get a single CPU that's capable of 16 cores. The 16-core Core i9 7960X retails for around $1700, whereas I can pick up a dual socket Xeon E5-2690 (v1) for less than $700 for the entire system and the performance difference isn't substantial (unless you're trying run AVX512 code, for example, in which case, you'll have to get new processors anyways, and then maybe a single Core i9 7960X makes sense).

    Course, the other piece of the puzzle also depends on how much memory you need to do what you're doing.

    For the computer aided engineering and simulations, some of my work will blow through/past 128 GB of RAM without any issue at all, so the dual socket Xeon platform supports a LOT more memory. (Core i9 7960X goes upto 128 GB of non-ECC, unregistered RAM, while even my first gen Xeon E5-2690 will support upto 512 GB of load reduced, ECC, registered RAM.) (The RAM would be the most expensive component.)

  12. I have a HP xw8600 Workstation – Intel Quad-Core1 Intel Xeon processor2 54053 2.00 GHz4 2×6 MB L2 cache 1333 MHz FSB5, 5400 Chipset, Dual CPU Motherboard. Currently running 1 CPU in it. So I'm looking for another CPU, and more RAM (128G RAM Max.) I have Linux Ubuntu Studio on it now. I'd love to use it as a gaming Server..

  13. "I don't believe that vendors move a ton of them" Just a few years ago 80% of the server market was dual socket. Go look at AMD's Epyc roadmaps and competition slides, they confirm this as can Gartner http://3s81si1s5ygj3mzby34dq6qf-wpengine.netdna-ssl.com/wp-content/uploads/2017/05/amd-xeon-two-socket-skus.jpg

  14. -.-' if they had these 2 processor motherboards in AM2+/AM3 Socket format they would be soo much more useful to the gaming community -.-' we could potentially make 4, 6 or 8 core budget rigs with these overstocked ass grade Athlon ii x2, x3 and x4 cpu's…

  15. What I'm looking forward to:
    16C/32T Zen2 (AM4 socket). If this ends up $700USD or less I'll be happy. Love to see how it scales in things like Handbrake, multi-tasking, and whether DDR4 bandwidth is much of an issue with Dual Channel. Probably want an X570 mobo with higher than 3200MHz memory.

  16. 112 logical cores in a single chassis is for a very specialized user, probably primarily scientific workloads running smaller scale versions of code intended to run on a supercomputer are going to be the main use.

  17. I tried to convince my friend to buy a dual socket motherboard when he build his Intel Core 2 Extreme desktop. The CPU he bought was almost $1100 when it was new but I knew it would become obsolete very quickly and drop in price.

  18. Why not just make a CPU the size of two and just have everything in one? Or is there S reason why the CPU should be small. I always thought the bigger the brain the more intelligent

  19. Q: what is the #1 rule in Dollar Shave Club?
    "close-ly-er simulaneous-ly-er physical-ly-er"
    'nuff said!

  20. I need a little bit help (sorry for my english i m from greece i dont speak very good). I have a workstation with one XEON E5-2660 8 cores and 16threads, and one GPU RX560 4GB , I want to change my GPU and I m between a used RTX1080 8gb and a NEW QUADRO P2000 5GB (are in the same budget 350-450€). Ι need it for works like CAD, SOLIDWORKS, INVENTOR and a casual gaming (PUBG & DOTA ). Can someone Help me?? Please!!! Thank You

  21. With threadripper can you use virtualization and divide the cores and threads into 2 systems for gaming and blender operations?

  22. Can anybody please explain what is exactly socket..? Is it better to have 2 socket server instead of one soc for database server? is it i have 2 physical procesor or cpu means it is 2 socket server? How does this socket helps in performance? Can anybody help me to understand in simple english? This guy just said bunch of craps which didnt seem to include the proper explanation of socket and how does it help in performance.. or how does it work with the memory..

  23. I just built a Threadripper 32 2990W, 256GB DDR4 4000, 2x WX-9100’s and a Titan Z CEO for rendering (came out of my gaming machine). I use it primarily for DaVinci Resolve 16, editing 4,6&8K video, AfterEffects, Maya and Blender. I have yet seen a slow down in performance our where I though to myself, I need an additional CPU. Though I will definitely be buying the 48 or 64 Core variants when they become available.The thing is a beast, even with WX-9100’s that turned out to be excellent cards for the type of tasks listed above, especially Open CL.

  24. Got a question: Is it possible to set up a WS C621E SAGE with a single CPU and add the second one later on?

  25. Where is my modern, dual CPU gaming PC, where I can tell 1 CPU to run my game, and the other CPU to handle OBS video recording..? Why is this not available yet in mid-2019???????

  26. Man, I'm late to the party, but I really wish you guys tested that Scalable setup against a top-of-the-line Xeon W, not a 7980XE… 🙁

  27. 8:50 As a developer I need this, because i run multiple containers and I need to do serious load testing on them.

  28. I had a 64-core gaming system with 1024 GB of 10GHz DDR9 and four Quadro RTX8000 running SLI. Then I suddenly woke up.

  29. I have a problem with this very same Motherboard, I'm using only One CPU (Xeon Gold 6134), however the motherboard doesn't boot and the error code shows only CODE 00, not doing anything else, can someone help me with that? What should I do. This was the first time that this motherboard leaved the box, we are trying to built this new server, however it does not show anything else, only ERROR CODE 00.

  30. Oh you like expensive stuff???

    You should probably get apples new pro stand that is made out of crushed soda cans that cost 999$

  31. what if you activate all the core (backup cores in the CPUs). This would make it a 112 core PC! Then overclock both CPUs to its max. Jeez that would be a small supercomputeer

  32. Dude it is 2019, the mid 2000's is 2050, but to be real it's 2,500 AD to be mid two thousands … are you time travelling or stoned?

  33. I do imagine that a dual socket motherboard used to be needed back in the late 90's and early 2000's when CPUs were only single cores, don't think they are much needed now a days unless you say run a large business and you have say hundreds of people using the PC at the same time.

  34. my first pc purchase was a 486sx, ran win 95 on it and doom 3d. Had a Paradise 3dc video card. Burned out 1st card they gave me with na literal hole through gpu. Paradise ran great.

  35. I use Visual Studio with my home build server – the project I am involved with is very large. See my server here https://youtu.be/XS_ssdhdX48
