I'm not defending the 6,1 Mac Pro...I am a huge fan of PCIe slots and tower cases. However a RAID configuration was being compared to a non-RAID configuration. A dishonest comparison. The 6,1 Mac Pro can be configured to support RAID so it too can offer comparable speeds.
What I'm saying is that it CAN'T offer comparable speeds. It can not. It doesn't have the capacity to run data through that x4 lane thunderbolt port. And when it was set up to aggregate two ports at great, great expense, it STILL could not offer comparable speeds. That is an honest and truthful comparison, and fact.
You keep saying you're not defending the 6,1, but it really, really looks like you're defending it with all the stubbornness you can muster. I bet there's something the 6,1 can do faster, but if you have a 4,1 or 5,1, the chances are extremely high that it would cost more to switch over to the 6,1 to accomplish it, and then you're stuck there within that tube with a smaller power supply, proprietary GPUs and bottlenecked Thunderbolt situation. That blows. I've upgraded my GPU, CPU, RAM, disks and PCIe slots with the times, and with the 6,1 you can only do RAM and that one SSD, and attach a bunch of TB stuff at x4 lane speed max. Well, I've read here that some have put in a new CPU, too, so there's that, thankfully. Are there any cases yet where someone has added a second SSD inside the 6,1 by means of some sort of splitter or anything? I haven't heard, if so. Are there any aftermarket GPU options? That would be cool.
I wanted to like it. I looked long and hard at it, and did some homework. The homework showed that the prior generation(s) have more potential than the tube in the case of expansion and data throughput. I have USB 3.1, RAID 6... everything but Thunderbolt, which I decided was the wrong direction in 2013. Here we are on the doorstep of 2017, and I have no regrets.
This
is apples vs. oranges. The old MP is different than the new MP. Apple made it that way. The point being made was, one can be faster than the other. It seems to me like you're saying either one can be fastest. Sure, but there is more potential for the older version to be faster than the newer version by means of a variety of tweaks, the two biggest of which are GPU and x16 lane PCIe slots. No matter what, the nMP cannot overcome those two advantages by nature of the restrictive x4 Thunderbolt configuration in place of x16 PCIe slots, and the GPU options that keep getting better are furthering the distance between GPU options. The only way a nMP can be faster is if you put two unmodified Mac Pros (for sake of argument, 5,1 and 6,1) to a test, and pick a task that the nMP was made for. Am I right, or are you feeling there's a magic loophole somewhere?
