Hello All
I have been following this thread with great interest now we actually have some prices and a few Geekbench 3 scores after months of pointless and groundless speculation.
I do a lot of rendering and use my all the 12 cores on my MacPro 3.33 Ghz machine heavily. I actually get 24 rendering threads which really helps with my productivity.
I bought a second hand machine that had been upgraded with a new processor tray by the seller. It cost £3600 including VAT. Not cheap I know, but these are hard to find and hold their value.
The machine gets a floating point integer score of 32000 with Geekbench3
The barefeats.com website has a leaked score for the nMP 12core 2.7Ghz with a floating point score of 38000, approximately 19% faster, for a cost of £5700 inc VAT with a base model with the only improvement being the 12 core 2.7 Ghz processor.
My second hand and upgraded machine is equivalent to an 8core in floating point performance ( I know that in other areas these nMP's will be much better, but my big aluminium enclosure also contains 3 x 1TB drives and an SSD. I also have a host of external firewire drives and two old fashioned non thunderbolt Apple monitors. These would all need new adapters or new external enclosures if I wanted to use them with the nMP)
I have embellished an earlier chart and added some core totals (assuming all 12 cores are under load, whilst rendering for example) and some estimated Geekbench 3 scores, assuming a linear correlation.
I would like one of these nMP but would benefit most with the new 12core model, but right now I am very happy with my old, secondhand Mac Pro which is not so shabby after all.
