AccuRender nXt

advanced rendering for AutoCAD

Can somebody give me a hint-

what is better / faster in rendering speed:

2 physical processors or, lets say one xeon with 8 cores?

Thanks in advance,

Physical cores and physical processors are basically equivalent.  

Intel chips, in particular, make a distinction between logical cores and physical cores.  Logical cores help a little, physical cores help a lot.  So-- for example-- your Xeon might have 4 physical cores with 8 logical cores.  This is a pretty common specification.  Don't pay much attention to the # of logical cores.   As a rule of thumb, use:

(# of physical cores ) x (clock speed) as a rendering speed index.

2 physical CPUs (let's say two AMD Opterons) with 4 cores each = 8 cores X 17600MHz (2X120=240euros)

1 physical Xeon with 8 cores = 8 cores X say 2400MHZ = 19200MHz (but 1400euros!!!)

The question is also the data throughput between CPU and memory and other significant aspects. Try to investigate some sites with benchmarks (Like Tom's Hardware showing results of rendering benchmarks like Cinebench and others), they are adequate for comparison purposes as regards the nXt.

Your information helps a lot, thanks!

But as always, Randy Newman is right - it's (always) money that matters... .

Intels pricing is a class of its own.

Purchased a new subscription to Autodesk. When I logged into Autodesk, it automatically upgraded my version I was using and installed 2021 version. Now my AccuRender NXT does not work nor will it load on 2021 version.I have spent the last 3 weeks trying to get support but I am not receiving anything.I have paid and downloaded the latest version of NXT but it's not working nor is the support working. Having been an NXT CUSTOMER for many years, I am extremely disappointed in the support.Not sure…See More
