Disabling CFX would drop power consumption, but I didn't always see a corresponding decrease in performance. I did the latter and found that despite the option being there I couldn’t actually disable CrossFire X under Windows.
Apple’s Boot Camp drivers ship with CFX support, and you can download the latest Catalyst drivers directly from AMD and enable CFX under Windows as well. Under Windows, that amounts to basic CrossFire X support. With two GPUs standard in every Mac Pro configuration, there’s obviously OS support for the configuration. I believe Apple also integrated CrossFire X bridge support over this cable.
Similarly, CrossFire X isn’t supported by FirePro (instead you get CrossFire Pro) but in the case of the Dx00 cards you do get CrossFire X support under Windows.Įach GPU gets a full PCIe 3.0 x16 interface to the Xeon CPU via a custom high density connector and flex cable on the bottom of each GPU card in the Mac Pro. FirePro GPUs ship with ECC memory, however in the case of the FirePro D300/D500/D700, ECC isn’t enabled on the GPU memories. I’ve tossed the specs into the table below:ĭespite the FirePro brand, these GPUs have at least some features in common with their desktop Radeon counterparts. The D300 is Pitcairn based, D500 appears to use a Tahiti LE with a wider 384-bit memory bus while D700 is a full blown Tahiti XT.
FirePro D300, D500 and D700 are the only three options available on the new Mac Pro. These are 28nm Graphics Core Next 1.0 based GPUs, so not the absolute latest tech from AMD but the latest of what you’d find carrying a FirePro name. The new Mac Pro comes outfitted with a pair of identical Pitcairn, Tahiti LE or Tahiti XT derived FirePro branded GPUs. The new Mac Pro is no exception as it is the first Mac in Apple history to ship with two GPUs by default.ĪMD won the contract this time around. This is true regardless of whether we’re talking about phones, tablets, notebooks or, more recently, desktops. If this is the case for you, then you need to use Wired Ethernet for the NIC dedicated to the VM's!Īnother issue that can arise if using a WiFi NIC dedicated to the VM's, some WiFi Routers will not allow bridging multiple IP Addresses to the same MAC Address.The modern Apple is a big fan of GPU power. Note: If this doesn't work for you, although as described it works for me, you may need to select Manually for the Configure IPv4: and use a Reserved Address in the Range previously mentioned with a 255.255.0.0 Subnet Mask while providing appropriate Host LAN's Router Gateway and DNS Server IP Addresses.Īnother issue that can arise if using a WiFi NIC dedicated to the VM's, some WiFi Routers will not allow bridging multiple IP Addresses to the same MAC Address. Now the Virtual Machine will acquire it's Network Configuration Information from the Host LAN's Router or you could assign appropriate Static IP Address, Subnet Mask, Gateway and DNS Server IP Addresses in the Guest OS's NIC configuration, if you so choose.Target Virtual Machine Settings > Network Adapter > Bridged Networking, select the NIC chosen for VM dedicated use. only for the VMware Bridge that will be set in the next step.ģ. This is the Address Range for Automatic Private IP Addressing that would normally be assigned if the NIC did not have connectivity however not to worry, it will. Then for IP Address: use a Internet Assigned Numbers Authority (IANA) Reserved Address of 169.254.0.0 through 169.254.255.255 and click Apply.
