Hardware Q: 3.7GHz 6-core vs. 2.7GHz 12-Core CUP


Hi, this article was super helpful in helping me think about an upgrade option. But I have a question for the community: I am considering a processor upgrade on my MacPro. 

* Current: 6-Core 3.5GHz, 12MB Cache

* Potential upgrade: 12-Core 2.7GHz, 30MB Cache

My only concern with this upgrade is that although I am doubling the number of cores in the processor, the speed is roughly 25% slower. Will that offset most of the "gains" I am getting with this upgrade? Although the cache size also more than doubles but I am not that technically savvy to evaluate the differences. 


Rest of my config:


* 32GB to be upgraded to 64GB memory

* AMD FirePro D700 6GB


Follow-up Q: I am considering the OWC Upgrade Service for MacPros which do not offer upgrade of the graphics card. Any recommendations there?


Thanks a million,



Maybe consider E5-1680v2. It's an upgrade in both ways.



Just bought one and I am preparing to upgrade that myself, though I would not recommend that to others especially ones not familiar with the machine in question. And 128GB RAM and 2TB NVMe with sinTech adapter.


Your GPU is a max one already, you can't do anything but try to use eGPU with a hack, like I do. Both RX 6800XT and Radeon VII in Razer Core X work good enough. Even RedShift recognizes the eGPU and accelerates renders with it.
