It doesn't work that way. Just "stringing" some computers together is not the same as having it in one computer on your desktop. You have a "gaming" system without the support that goes along with it. Junk. And it hits 22TFlops in the iMac Pro.
Yes, it does work that way.
There have been many processors connected together that, when working together become supercomputers. The Scorpion may not be designed to be strung together to get to supercomputing power, but the processors can be divorced from the platform and put into different platforms to create a much more powerful computer.
The Xeon configuration that Apple uses is not exclusive to Apple, and any OEM can do the same, and perhaps a lot less expensively. But, there has not been a big need for such computers in the small business space or in the regular consumer environments; what Apple is simply doing, is trying to regain the WOW factor that they lost some years back, but that iMac is not going to get it done for Apple, since what the Macs used to be used for, can now be done with PCs at much lower costs and without the stupid wow factor.
Apple needs to move on and forget about their deception with the iMac.
BTW, by the time that Apple releases that computer to market, others may have copied the configuration and at much lower costs. That iMac is not scheduled to be out until some time next year, and perhaps never. It remain, for now, a talking point and smoke. And since it’s way too expensive, even for the target audience, Apple may be forced to drop the whole idea.
Oh, BTW.
I noticed how you compared the iMac prices with the price of a “similarly equipped” PC, where the PC came out losing by a couple thousand.
BUT... your sample was very dishonest.
For example, that “similarly equipped” device was for using off-the-shelf components to build that PC. Yet, no OEM would be charged like a regular customer for those components, and if an OEM were to build a similar configuration PC, there is no doubt that that PC would come out ahead of your iMac price. In fact, the similarly equipped PC at lower cost, would automatically be a better buy, simply because it would come with Windows 10 Pro,which could do a whole lot more types of applications immediately without any other “special software or hardware”.
