Hi guys,

Sorry for making a new thread, I`ve read through the existing ones but just wanted to check the specs on this exact pc with you.


Im changing my work computer, and the It-department has come up with a suggestion in terms of hardware.

Double Intel Xeon E5-2620 v3/6 cores, 2,4 ghz)
Graphics: 1gb Nvidia NVS 315
Memory 32gb(4x8gb) 2400mHz DDR4 RDIMM

IT also suggested we`d switch the graphic card to NVIDIA GTX 1080.

As of now my personal 2013 MacBook pro is working much better than my 2016 Lenovo Laptop.

Is the new machine a good upgrade? I want faster renders and the ability to work with high poly models(large-scale urbanism projects, often 300-500 mb su-files.)

I really have no idea myself if this an actual upgrade or if my MacBook still will be superior. 

As far as I`ve understood Sketchup only uses one core regardless of how many you have. Does that mean that one would prefer a larger processor with less cores instead of 6 coresx2.4? My MacBook has 2.6ghz.

Really grateful for every little hint, this will be an expensive machine so it also needs to be worth it.

Your graphics card needs a minimum of 2Gb Video RAM, but you ought to aim for at least double that. For the scenes you model, it will be a huge improvement. Get as much VRAM as possible and the fastest graphics card you can afford. Massive SU files involve manipulating lots of pixels. You need a lot of graphics horsepower and memory for that!

For the CPU, SU doesn't really use more than a single core. The faster your CPU, the faster your single core will be in SU. The more cores you have, the faster your rendering will be. Therefore you get the fastest CPU with as many cores as you can afford.

32Gb of RAM is possibly a bit too much for most people, but probably about right for you. However - for the complex models you work with it's the Video RAM that is more important. 

I use a 2013 MacBook Pro every year at the AIA show in America and it's a fabulous machine! I'm not surprised that it's faster. 

Your new machine should be a lot faster than your macBook though.

I'd personally go with the GTX 1080, and someone on the forum juste tested the Ryzen CPU which will be much cheaper than an expansive Xeon!

The Ryzen has only been tested against an i7, not a Xeon, and the machine he proposes to buy has 2 Xeons [smile]
Different level of performance!

I'm the guy who tested the Ryzen against an i7. I should have included it in my test, but I have used Xeons before. I wasn't able to test it along side the i7 and Ryzen because I don't own the Xeons, it belongs to my work and they need it. With that said...

Unless you're only rendering with your machine, don't get a Xeon! As bigstick said, Sketchup uses single cores for the modeling phase. Xeon cores are not remotely as fast as i7 or Ryzen cores. Any benchmark you look up will show this. The thing Xeon has going for it is long life and reliability. Xeons are rated to be used in situations where the system is on 24/7. They're really expensive and you are likely to need ECC (error correcting memory) to use them to their fullest, and ECC memory is expensive and completely useless since almost all RAM has some sort of ECC built into it. If you're doing complex models, I would stick with ether an i7 7700k or a new Ryzen 7 CPU. While the i7 has better SINGLE core performance, the Ryzen renders about 70% faster for the same price. (Shameless plug to my test: http://supodiumforum.websitetoolbox.com/post/new-ryzen-cpu-tested-with-podium-8486921?pid=1295498150 ). The Ryzen is great for renders, but modeling is slightly better on the i7, but the difference isn't all that noticeable when you're in the model. Now, if your using other programs that heavily rely on single core preformance, the i7 is the way to go. For comparison, the closest CPU that competes with Ryzen in terms of MULTI core preformance (what Podium needs) costs $500 more (NOTE: I've never tested an i7 6900k, so I don't know if it matches up with Ryzen, but data from other programs makes it seem like it should).

GPU does not matter after a certain point with Podium or Sketchup. I've used FirePro graphics cards, AMD GPUs and GTX cards. Once you get above a GTX 960 (Radion 370), there's no perceivable performance improvements, assuming you have the VRAM to support this (4GB or more). And, in my opinion, a workstation GPU is worthless in Sketchup, as the new GTX 10xx series cards are by far the clear winners when it comes to power when compaiered to anything but TITAN GPUs and can do vertically everything a Quadro or FirePro can do. But again, like Xeon, workstation GPUs are rated for 24/7 operation. Just make sure your GPU has 4GB of video memory.


Here's what I would get, if I were you, given the info you put in your post:
CPU: AMD Ryzen 7 1700X OR Intel i7 7700k OR (i7 6900k if you want the render times of Ryzen and the single core performance of the i7 7700k AND you have the money for it).
GPU: GTX 1060 OR 1070 OR 1080 OR (GTX Titan if you have that kind of money and want all of the power forever).
RAM: 32GB DDR4 @2400Mhz
AND make sure you have an SSD in your computer. They make everything so much faster.

I don't know your budget, or if you have one.

One last thing if this wasn't clear... the i7 6900k costs $1000. It has the SINGLE core performance of an i7 7700k (best single core around) AND the RENDER times of of Ryzen (rough estimate). The problem is Ryzen costs $380 and the 7700k costs $350. So, you can splurge to get the best of both world or pick between the 7700k and Ryzen. If it wasn't super clear, I lean towards Ryzen for you right now [wink].

Nothing to disagree with here, good solid observations!

The one area where the Xeon shines is in multi-CPU configurations. There are few dual i7 CPU options.
The question is really whether you need dual CPUs at all if you can get the same number of threads in a single CPU.

For SU the fastest single core performance (more or less the CPU clock speed) is going to be the most important thing, but a lot of the load in SU with large models is the graphical performance, which of course is down to the GPU.

There is some interesting information here:
https://forums.anandtech.com/threads/benefits-of-dual-xeon-in-2017.2504632/

Podium doesn't use the GPU a team the moment, but the next major version will. ProWalker uses the Nvidia GPU with the iRay engine which is fast in the interactive modes. We are planning to introduce a version using the AMD ProRender engine, which works on any GPU. The newer version of the Podium render engine also runs on any GPU using OpenCL. That will be integrated in Podium 3.

Thanks for all your help guys. We went with a double solution where we ordered a badass desktop computer for work and the best MacBook pro for working from home(maxed out specs), so I´m eager to try the new gear when it arrives in a couple of weeks!
