We typically don't publish reviews on enterprise grade hardware, but today we are taking a look at one of AMD's new EPYC processors from a different perspective. As we move towards more high computing devices like AMD's Thread Ripper processors, a lot of software applications will start to use more cores, so we will take a look at a processor with more cores than even the top level Thread Ripper CPU has to offer.
However, we will write this article, not as a review of the EPYC processor, but as a sort of comparison between workstation tasks and normal consumer tasks anyone who uses a workstation might use.
There are many people out there, especially with the gig-economy who need tons of cores, have the money to invest, but won't necessarily run enterprise software, but rather a mixture of content creation software and consumer software.
For starters, we get 24 cores and 48 threads. Each die would have six cores, meaning each CCX would have three cores. The base clock speed is 2GHz, with a Max boost clock of 3GHz, and an all core boost of 2.8GHz. There is also a total of 64MB of L3 cache, which is double that of Thread Ripper CPUs.
It also offers up an astounding 128 PCI-E lanes and a TDP of up to 170W. AMD has an easy to understand naming scheme in place for EPYC. If there is a P at the end of the model, then it's only meant for single-socket systems, and the dual socket hardware is disabled. The 7401 has the dual socket hardware enabled, but it's not being used in this case. Unlike Thread Ripper, EPYC doesn't require a chipset; everything is integrated into the CPU.
The CPU also supports 8 DDR4 channels, with up to 16 DIMMs and 2TB of memory. The system only supports registered DIMMs, NVDIMMs, or 3DS DIMMs. The way EPYC is set up, each die has its own DDR4 controller and IO hubs.
The EPYC 7401 costs $1999, and it looks like you are paying a tax for the CPU since the 7401P only costs $1,149. The only difference between the CPUs is that the 7401P isn't able to be in a dual CPU system.
