I am considering building an AMD TR2 workstation based on the 2950X and have done quite a bit of research into this.
In your Intel AMD comparison the AMD Threadripper CPU is almost half the price of the Intel CPU, so it is not a fair comparison at least for considering the price performance ratio.
A better comparison would be:
Anandtech CPU 2019 Benchmarks [www.anandtech.com]
Overall the AMD Threadripper CPUs have a much better price performance ratio than the Intel CPUs.
On the GPU side the current generation of AMD GPUs (Polaris and Vega) are much less power efficient and generate a lot more heat and noise than the NVidia 10xxGTX and RTX 20xx series.
They do however come in somewhat cheaper.
There is currently a glut of GPUs resulting from the collapse in demand for GPUs for mining Crypto and the launch of the new NVidia RTX series, so it is possible to get the NVidia 10xxGTX series GPUs at very attractive prices.
By the time the software supports the Ray Tracing features of the NVidia RTX series NVidia will probably have released upgraded GPUs which may well have 16GB.
Yes, you are right, with power and heat due to AMD Vega. But still.. it's such an opportunity to buy a 16 gig 1T/sec memory GPU for that price
With such a great computing power! I'm constantly reading after AMD's ProRender and trying to convince myself that actually it works well and rdy to use (but of course I know it well, that it's not even close to Octane or Redshift)
I 100% agree that Threadrippers are the best price/performance option in a workstation! No doubt about it due to the surreal crazy price range of Intel's X CPUs.
But, one thing is important and I'm honestly crossing my finggers, that AMD will handle it by the 3000 series, that they perform way under intel if it's about single core workflow. Actually every even extrude, move, rotate, scale, bevel, champfer…. first goes true a single CPU core and just than it reach the GPU that will send it to our display. So until active modeling we still need that good single core performance. And I do not even mentioning other softwares as Zbrush (I use a lot) that no matter if it greatly support multi threaded workflow in a superior way, a TR 1950 was able to reach the same Zbench score as a 6 year old i5.
That was said. But I also should share, that I'm absolutelly aiming for a TR 3000, probably I will have no money to buy one (they will be close to intel x at their arrival imo, more cores, but 1500+ pricerange) but I will wait just for it's new gen motherboards and drop a 1920 in it that I can upgrade by time.
Thanks so much by sending that link, you are right, if we compair these CPUs due to the same pricerange, than thats what we get, but careful there, AT's most benchmark line is multithread based, so it will show you a fake result compareing a 12 core cpu to a 16 core one (24 thread vs 32 thread). Any way, your decision is great! 2950 is a superior CPU! By the way, is it urgent? Can you wait for the new gen motherboards? Even if you will drop a 2950 in it, I heard that new TR motherboards will be more than a simple PCI 4 upgrade - worth waiting imo.
