Currently the best (to be more precise: fastest) workstations for this type of application is powered by one or two AMD Epyc 2nd gen CPUs.
But with Ansys Fluent the first question always has to be: how many cores can you use with your license. Last edited by flotus1; January 27, 2020 at 14:48. |

Then you won't have to use all of your budget. The fastest configuration for 4 cores is a Core I7-9800X, paired with some fast memory (DDR4-3600 or more) in quad-channel.

you and other expert recommended: i7-9800X (you) and i7-8700K (other expert).
Is that close? Also, we want to have 128GB, instead 64GB. But vendor said: "Dell states that we will not be able to do 128GB RAM unless the customer changes the processor from i7 to XEON PROCESSOR. The 128GB RAM only comes as 128GB (4X32GB) 2666Mhz UDIMM ECC memory and for ECC memory to be supported, the customer has to go with a xeon processor" Is it good for us? And what your opinion about Ryzen 7 2700X(8 cores)? |

As a side note: with the right motherboard and bios, it could handle much more than that: https://wccftech.com/asrock-x299-mot...upcoming-bios/ As for support of 32GB UDIMMs... I am not 100% sure. But there is always the possibility to use 8x16GB, as long as you get a motherboard with 8 DIMM slots. But all of this is a moot point if you have to buy from Dell. You will have to take what they offer. And memory overclocking won't be possible anyway. The I7 was kind of the budget oprion compared to a similar Xeon. It is cheaper, and with higher memory speed, it is also faster. But when buying from Dell, the budget character of the configuration is lost anyway. Quote:

Sure, why not. Maybe it will be a few percent faster than a Core-I7-9800x for your requirements.
