Posted by samerrustom Dear expert, I would like to buy a super powerful desktop for my Design department. I am thinking to buy PC with dual CPU, but I am wondering if these two CPUs will working in parallel "together" or the second one wait until the first CPU fully loaded. Please help me Please clarify what you mean with examples of your ideas. You can get CPUs with single, dual and quad core and more (For example see https://www.amd.com/en/ryzen) If you get a board with one of these then they will happily work together as long as you run programmes that can take advantage of all the cores. 1 of 4 found this helpful thumb_up thumb_down Hi there, dual processors work in tandem, and yes it will be beneficial to things like rendering or high intensive applications, all depends on what your requirements are https://techterms.com/definition/dual_processor 2 found this helpful thumb_up thumb_down  The way the cpu's will process your load depends on the software you'll be running too. What are your requirements? HP has plenty of powerful workstations that could
service you without a problem. Specify what software you want to run so we can come up with ideas. My personal wet dream of a machine would be HP's Z8 G4 that can go up to 3Tb of RAM but as long as we don't know more info from you it's hard to give proper advise.

However, whichever route you go down comes back to my first point, how much those CPU's get used depends entirely on the apps being used and whether they are multi-threaded or not, some might only run on 1 core, others might max out at 3-4 cores, others might be able to use many more cores, it is all down to how the apps in question have been designed and built. 4 found this helpful thumb_up thumb_down Harpy

For the most part, I recommend getting a single CPU system with bucket loads of cores. As Nick said, threadrippers are great for workstations, if you want to be on team blue however, Look for an i9-9980XE as this is the counter part. 2 found this helpful thumb_up thumb_down Keep in mind that for some design applications like Photoshop, faster cores are more important than more cores. AutoCAD same thing. 3ds max rendering benefits more from more cores and scales almost linearly to having more cores/CPUs. 3 found this helpful thumb_up thumb_down I suspect you see the over all message here. You should take a look at the requirements and specs for all of your design software and determine what their multi processor capabilities are before determining your best hardware requirements. feel free to reply with some of your design software and this group can probably help you with that decision. Are you an engineering design shop or graphic design?

That's like saying two bonded fast ethernet connections are faster than gig ethernet because the app is optimized to work with slower but more network connections. Faster cores are always better than slower cores - AMD is just trying to brain wash their way into more market share. This is why engineers I support that use CAD are sticking to Xeon E's and i9s and ignoring Ryzen. Also, there is a big difference with multi socket systems -vs- single socket systems running more cores. Multi socket present all kinds of NUMA issues to applications, and unless you plan on dropping a hyper visor on top and running multiple VMs the multi socket system will almost always have a performance penalty. 0 of 5 found this helpful thumb_up thumb_down Almost all desktop and server CPUs have multiple cores. As far as the software goes, this is the same as having two socketed CPUs. Most software nowadays will utilize multiple cores. However, a design software may not require a fast CPU but may require a high quality graphics video card. Check with the software manufacturer. They should have a set of minimum and recommended hardware requirements. Post those and you can get some better assistance.

In theory software would perform the
same way on a single 4 core 2Ghz CPU as it would on dual 2 core 2Ghz CPUs, but there may be other benefits of having multiple CPUs like increase over all memory support. Individual applications will all utilize CPU core, CPU clock speed(Ghz), RAM, hard drive/SSD speed, Video cards, and network speeds differently so it's nearly impossible to give generic advise. High clock speed, fast disks, lots of RAM, and a workstation class graphics card if used by the application are the generic
recommendations you will find. One factor often overlooked is stability. Depending on the type of design work tolerance for down time or crashing may be lower than other system in the office, so items like ECC RAM,workstation class motherboards, quality of power supplies, redundant hard drives, and UPSs may become areas where spending money may be helpful. Was this post helpful? thumb_up thumb_down To simplify what everyone else has said: Years ago, a single CPU was a single 'core'. Some big servers and Design computers had two or more CPUs. More recently, many cores could be put on one CPU, so new CPUs can be dual core, quad core, or eight core. Big servers can still use many CPUs, but those are BIG servers. You can get a really fast Design Workstation today with only one CPU with quad cores, like an Intel Core i7, Core i9, or Xeon e3 or e5. The more you pay, the faster it goes. Combine it with lots of RAM memory, 16GB or more, a good (expensive) graphics card like an nVidia Quadro, and an Nvme SSD drive, and you will have a VERY fast system. So the question is, how much do you want to pay? Was this post helpful? thumb_up thumb_down Someone needs to clarify the difference between sockets, processors and threads Sockets means physically plugging the device in. I think this is what your asking. Usually only on server main boards and workstations but have been on consumer main boards a couple of times in the past processors can be multiples usually now they are 4 , 8 and 12 + Can have multiple threads per processor but better to refer to threads as individual functions being performed by the operating system. some threads can be shared by multiple processors and some processors can perform 2 threads on the same processor at the same time.

Unless your using a heavily threaded application like video encoding or rendering where having 64 cores available at 3.2 GHz is much better than 8 cores at 4.2 GHz 1 found this helpful thumb_up thumb_down Dual high end Xeons, NVME SSD hard drives, 64GB of RAM, high end Quadro and expect to pay $10K+. Before you buy make sure that the software can utilize the dual processors. 1 found this helpful thumb_up thumb_down Hello, I suggest a multi core CPU with 4 or more cores. Multicpu is great but often not required for a desktop environment. As to the rendering software most popular titles will take advantage of multi core/multi cpu as well as use the GPU for rendering. I would highly recommend to look further into what GPU you buy as the GPU will do the bulk of the work in rendering. Was this post helpful? thumb_up thumb_down "Unless your using a heavily threaded application like video encoding or rendering where having 64 cores available at 3.2 GHz is much better than 8 cores at 4.2 GHz" Even then, it is extremely dependent on the footage and what part of editing you are in. https://www.pugetsystems.com/labs/articles/Should-you-use-a-Dual-Xeon-for-Premiere-Pro-CC-2017-932/ The point of this is to say, @samerrustom, that dual CPU is probably not something you should invest in. I used Premiere as an example since Adobe is the industry standard, and most other design software functions similarly, not just for video editing. Chances are, if you have the sort of software / system configuration that can benefit from multiple CPU, then you are intending to virtualize on a server level (for any number of reasons), not just run powerful applications. Personally, I would recommend using a very high end single CPU and use the saved funds to invest in RAM, GPU, storage, networking, or another critical aspect of the design environment. And can we all please stop saying "SSD drives"?? :'( 1 found this helpful thumb_up thumb_down
Maybe I should have clarified single socket 64 cores vs single socket 8 cores. 64 cores on a single socket is not going to have as much latency as a 2 socket setup with the same amount of cores in total. To correct myself the new Ryzen has 32 cores and 64 threads (I said Cores) the new i9 is 8 cores and 16 threads (for some reason I remember reading something about Intel dropping hyper-threading on the i9). Maybe have a read about encoding content with x.265 and how many threads are available per frame. You can saturate even the Ryzens 32 cores in a single encode if your content has a high enough resolution ie 4k 8k. Was this post helpful? thumb_up thumb_down Sadikul

New contributor sonora I think dual CPU's refers a computer with two seprate processor. two processors work in tandem to process using technuqe called multiprocessing. are split between the two CPU allowing the PC work faster than a simillair machine Was this post helpful? thumb_up thumb_down i used to run a dual cpu Xeon machine...it had almost no speed benefits. if anything it seemed slower. Was this post helpful? thumb_up thumb_down completely depends which software your design department are using, for example if they are mainly using adobe photoshop and premiere, then they'd be better of with a smaller number of higher clocked cores (i9 9900k or similar, which is 8core 16thread, or even a 9700k - 8c8t). If they are using blender then they would likely be better off with more cores clocked at slightly less (e.g AMD threadripper 2920x through to 2990WX, or intel socket 2066 chips- 7900X - 9980XE). Similarly, different programs may make better use of larger amounts of RAM, or faster RAM, or GPU acceleration, without knowing what software, it's not possible for us to give you the
'right' answer! Was this post helpful? thumb_up thumb_down Buy a machine with the most CPUs with the most cores with the highest speed you can get.

We just spent $3.8K apiece on a few CAD machines becuase the end users didn't believe that their machines were specced high enough and that was causing their software to perform poorly, so they went over my head. Now they have $3.8K machines that perform just as well as the $1.6K machines I bought for them two years ago because it turns out, like I said, the hardware isn't the problem. The software they're using is just written poorly (as confirmed by our reseller when they didn't get the performance boost they were expecting). My response? "I told you so." 1 found this helpful thumb_up thumb_down
Yes, possibly, it depends on your application design. from Multiple CPU Vs. Multi-Core: Either multiple CPUs or multiple cores require software programmed to recognize them. Operating systems, such as Linux or Microsoft Windows, began on single-CPU, single-core computers. Versions that recognize multi-core computers require additional programming effort. Unless the software knows the difference between single and multiple CPUs, it will act as if the computer has a single CPU, and the other computing resources will remain idle. The same goes for application software. For example, a 3D graphics modeling program may run no faster on a single-core computer than a multi-core one. If the program can split up CPU-intensive tasks and assign them to different cores, the program completes those tasks more quickly. TLDR: You need to look at your target application and find out if it favors multiples of CPU's, Core's (thread's), or both. 1 found this helpful thumb_up thumb_down
Honestly, this is so true. In a similar situation our VAR actually told us to just buy refurb, ignore the core count as the program couldn't really make use of more than a single one anyways and spend the money on the GPU and RAM as that is where most of the bottlenecks happen for this application. Now of course that happened after the manager of the department got to spend $4k on each laptop... They sure do boot up fast though. 1 found this helpful thumb_up thumb_down
Just an FYI Autocad is releasing multi-cored support 'soonish' (more toward the manufacture Autodesk as they're putting more multi-cored support in all their products). I don't remember the whitepage's exact dates, but the 2020 version should be vastly better at multi-cored support. Inventor likes the FPU from Intel, but if you don't care about .5 seconds of random context menu load time the AMD's 1700x can crush
multi-window/model of '19 with no issues (simulation seems to be obliterated by the AMD as well, very very good results). In comparison the 1700x is on par with a more expensive (same gen range) Xeon e5 (Gold now? forget their new designations). I'd like to get my hands on a Zen Gen2, but yeah....

For some applications faster cores are preferable and for others more cores are. The OP needs to research
which is better for the applications intended to run on the proposed workstation. But I agree that a multi-core single socket system is generally better for most end user programs. Was this post helpful? thumb_up thumb_down Processes are assigned to a processor (CPU, core, use your own words) when they start. Having multiple processors allows processes to be split among processors, which is generally a good thing considering you would have 80 to 100 +- processes running at any time. But each process runs on only one processor as it's launched. You may see multiple instances of things like IE running on different processors. In Task Manager you can show the process ID and the processor that was assigned to it when it started. You can tell your computer to always use a particular processor when running a specific process - that will probably be something you regret at some point so you shouldn't do that except for freaky exceptions. If you had 8 wagons (processes) and 8 healthy horses (processors), each wagon would be connected to its own horse. Adding more processors doesn't add more horses to the same wagon. Expanding that, each horse can pull multiple wagons but a wagon is only pulled by one horse. But adding wagons to a horse makes the horse run slower. So if you had 8 wagons, having 9 or 16 or 100 horses would be no better than 8.

Since this will be for the design department it's better to focus on the
right graphics card which will likely be doing most of the work. 0 of 1 found this helpful thumb_up thumb_down

I'm being sardonically serious. If you buy anything but a "check all the boxes" PC, and the user complains, what can you say? Are you going to start explaining about NUMA or memory paging or cores and hyper-threading? Maybe, but the real question is if it would do any good. I say no. All you can do is say, "It was the most expensive one they had" and move on. Was this post helpful? thumb_up thumb_down Dual socket CPUs and using one CPU with a ton of cores are two different ballgames. I would highly suggest an AMD Ryzen Threadripper CPU if you are doing heavy workloads that utilize multiple cores/threads. Trying to do like dual Intel Xeons or something of that sort will be a lot more expensive (more expensive motherboards, memory, etc) and may not be worth it for the little to no performance gains. It all depends on workload though and how the applications use each kind of hardware. Was this post helpful? thumb_up thumb_down
As others have stated, this really comes down to the software they will be running on the system. sure, you could easily spend $5 - $10k on an awesomesauce system, but if it turns out the software can only utilize 1 core and you got them 32 at 1.8Ghz, you will wish you had a hex core with turbo up to 4.7Ghz... my last engineering boxes were just Dell Precision T3630's with an i7-8700K, 64GB RAM, 512GB "Class 50" NVMe SSD @ around 3.2Gbp/s read and a single 8GB Quadro P4000. systems were just under $3k before tax and are pretty speedy. these systems mostly run Creo and some Solidworks. not a lot of rendering happening, what we mostly need is Single Core performance. Solidworks and I think a lot of other software can't utilize dual graphics cards. all that to say, need more infos! Was this post helpful? thumb_up thumb_down Bill6324

For instance Windows 10 Pro is limited to 32 Threads. It would be a shame to spend money on High End CPUs that you then couldn't fully utilize.

How do I connect 2 CPUs together?Step 1: Connect two Computers using an ethernet cable. Step 2: Click on Start->Control Panel->Network and Internet->Network and Sharing Center. Step 3: Click on option Change Advanced Sharing Settings in the upper-left side of the window. Step 4: Turn on file sharing.
Can I combine two CPUs?no. There are two separate cpu cores, each with its own set of registers, program counters, MMU.
Can you make 2 computers run as one?There are many ways to connect PCs, but the most used and easiest one is through a network connection. You go out, buy a switch and some LAN Cables, and hook them all up to each other. Servers work the same way.
