We’re getting a new PC. Here is the information about the current two computers that we have as well as possible upgrades. In the bay, the computer on the left side of the desk is from MSI, the one on the right is from Gigabyte.
The computers are primarily used for Solid Works, ANSYS, CAD, and for running simulations so the priority here will be on the CPU.
Computers in the Bay: (for comparison)
Component | MSI PC | Gigabyte PC |
CPU | Intel i7 - 3820 3.6 GHz 4 core | Intel i5 - 6600k 3.5 GHz (3.7 GHz) 4 core |
RAM | 16 GB 1600 MHz | 16 GB 2133 MHz |
Graphics | GT 610 | Quadro K620 |
Storage | 1 TB WD HDD | 1 TB / 120 GB WD / ADATA HDD / SSD |
Minimum system requirements for what we’re using: (ANSYS, Solid Works, CAD)
16 GB RAM, 3.3 GHz processor (4 core).
While Solid Works does support multi-threading, it is better to use more single-core powerful CPUs. The reason for this is because of task dependencies. There could be multiple processors working on tasks simultaneously but if one processor is waiting on another to finish its task, then it must wait until its done. Therefore, faster cores > more cores.
Side note: I did consider the new processors from AMD (Ryzen) however due to the above statement, and benchmarks from other users, I decided to go with Intel. (Benchmarks).
Possible Specs for New PC:
CPU | Intel i5 9600k ($300) / i5 9600kf ($250) The difference between these two processors is the i5 9600kf does not have integrated graphics and is about $50 cheaper. If we are willing to invest an extra $200 into the CPU, I can get us an i7 9700k which performs better than the i5 (see benchmarks from above). |
RAM | 16 GB 3000 MHz 32 GB would be ideal, but it is an extra $100. Also, more RAM can be installed in the future if needed. |
GPU | NVIDIA Quadro P620 (see comment under Custom Built) |
Storage | 512 GB SSD M.2 NVMe |
$1276 - Custom Built PC
In the custom build, I included a monitor (about $130 dollars) however if we have extra monitors laying around, we don’t have to buy a brand new one.
The graphics card works for the needs of the team however for about $200 more, we could get a much more effective card (NVIDIA Quadro P1000).
The build does not include any peripherals (mouse, keyboard etc.).
$1389 - Refurbished PC I found on Amazon within the price range.
This PC is prebuilt, has a decent processor, a better graphics card, same amount of RAM, and more SSD storage. However, this computer is refurbished (used), and the components are much older than the custom build PC.
Does not include a monitor or peripherals.
Comment: Looking at Amazon, a quick scan of the page shows the prices of similar computers to be around $4000 for similar specs (16 GB RAM, similar processor etc.). Also, the refurbished model I recommend here is $2442 before the sale.
