Hi.
You can buy the fastest, most multi-core processor and still feel small. Buy according to your budget.
about me 2 xeons 28 cores 56 threads. This is not enough.0 -

Hi,
sorry for the late reply, thanks ottoline and vadsura.
I want to explain my question better.
I currently own a 6 years old macbook pro:
PROCESSOR: 2,5 GHz Intel Core i7 quad-core
GRAPHIC CARD: AMD Radeon R9 M370X 2 GB, Intel Iris Pro 1536 MB
MEMORY: 6 GB 1600 MHz DDR3
With this gear i feel like a donkey that pulls a a train.
This is how i spend my days:
When i start create my garments and i have a couple of clothes in my scene if i move a line i have to stare this for a while, even for a couple of minutes.
So i just need to overcome this situation and upgrade my gear to a level that this does not happen.
I supposed that for complex garment creation phase in clo 3d is more important GPU. isn't it ?
Which kind of configuration i need to be sure to create complex garment avoiding endless loadings?
Thanks in advance for your suggestions.

Is the CPU clock speed (GHz) come with > turbo. The clock speed is what will give you faster simulation, a turbo boosted CPU that achieves a higher clock speed should be okay, but if your CPU is limited to 2.5Ghz - then that's possibly why it's slow. The GPU is for look dev simulation when working, for the final simulation you need to run it using the CPU, and that is where the clock speed (Ghz) is crucial.
Check your CPU type (find the exact type and post that here ) and see if it has turbo feature for ramping up the clock speed > then make sure its working optimally.
I would want to be using a CPU with at least a base 4 - 5 GHz clock speed. The simulation FPS (Frames per second) time step is based on the computational speed of the cloth collision. A 2 GHZ chip would be about half the process speed of (fps) to a 5Ghz CPU chipset, so that means it would be slow for final beauty pass cloth simulations and synchronization at low particle mesh distances if there is no GHz turbo feature on the CPU.
Flick up what your CPU chipset is and maybe we can give you some feedback.

Hi ottoline,
i don't think i have fully understood your reply but i think this is the key for my upgrade, so i hope you'll help me to go deeper.
1) Is this CPU clock speed the key factor to consider for the performance improvement in Clo 3D ?
Or you think is also important to upgrade the RAM to some crazy level like 128GB?
2) If i Buy a an INTEL i9 10900K, 10 cores, 20mb cache and from 3,7 to 5,30 GHz in turbo boost mode,
you think i will be able to work smoothly or i will still have long stops in the workflow ?
3) After a brief serach i didn't find CPU that starts from a base of 4-5 GHz. Most of them start from around 3 to then arrive in turbo boost at 5. Isn't it?
4) Please can you clarify which is the LOOK DEV simulation and which is the FINAL BEAUTY PASS simulation ?
Thanks a lot for your help.

As long as the chipset has a turbo boost that is greater than the base clock speed and upwards of 5Ghz that will work well. Cloth collision (the high quality beauty pass) is all about the maths processing and that requires FPS time steps that are inherently sequential. So although there is the GPU simulation for work in progress mode, your best tool for rapid work after the initial assembly and for accurate cloth simulation will always be the CPU clock speed (Ghz). So the intel i9 you quote will be fine for the refinement stages of the cloth simulation. You don't need a base clock speed at 4-5Ghz unless it's a non-turbo (older type CPU chipset) from your previous description it was hard to establish if that was the case (hence my question) if you are getting a chipset with a base speed (eg: 3.7Ghz and then it turbo boosts to 5.3 Ghz that means it will speed up when it is tasked with the high quality cloth sim, the fan simply kicks in on the CPU as it heats up for intermittent acceleration) and that will be fine with CLO3D.
For good GPU simulation (Look development mode) which is the drafting of the 2D pattern pieces and basic sewing assembly around the avatar, basic posing and preliminary drape use the GPU simulation mode, which means you also need a good GPU graphics card, so this is speedy. However as rendering and external applications is where the GPU is also mainly used on any workstation you would be best to consider the choice of GPU based on the render needs you have within your pipeline and with CLO3D. So if you were also doing external rendering and handling large scenes you would look for the ability to load big files into decent amount of VRAM and maybe the type of render engine you may use (GPU verse CPU). eg: vray >> see article and if you were doing further external (from CLO3D) render or texture work you may look a the GPU as part of that hardware need to support what you do in digital clothing.
The final garment layering assembly and cloth simulation refinement is best done with the CPU (CLO3D recommend this) as the cloths physical simulation and cloth collision performance is best done on the CPU, which means after the initial drafting and sewing together of the pattern pieces, and assembly around the avatar of the garment and 1st simulation > you often need to shift into the refinement stages of arranging the garments cloth at higher resolution (smaller particle mesh distance) and tweaking the quality of the creasing and detailing around the final garment simulation, into the final simulated cloth pose - >> I call this the beauty pass simulation, and it should only be done in CPU simulation mode where the simulation time steps are smaller and the physical fabric is calculated much more accurately, so the final drape of the cloth is at it's most accurate.
So when choosing your hardware it's not just about using it with CLO3D it is also about balancing out your hardware as a workstation to also include any additional software's you might include in your workflow. And in that approach I may have many application open at the same time where I need a lot of RAM for holding large image data and keeping that image editing task fluid, which is sepoerate to what I am doing in CLO3D, so RAM for keeping application open at the same time is always handy but not always a primary need. For example I run texture image capture as I work, and VR clothing simulation and for that I need a decent GPU graphics card with VRAM as opposed to standard RAM as I view that all in real-time at high frame rates using PBR materials, which is a separate task to using CLO3D but it factors into my over-all digital garment workstation workflow and hardware needs. It's a load balancing situation for any workstation based on how you intend to use your workstation and in what area of specialization, eg: modelling verse rendering verse cloth sim.

Huge thanks ottoline.
Your answer was very comprehensive.
Can I ask you how long have you been working in the industry?
Where is it possible to see some of your work?0 -
I don't show my work in this forum, only simple stuff that sits around the space of digital fabrics or some feedback on what happens to grab my interest, however my design work is all over the world, you just need to know where to look. 😉

Ok, show me where to look cause i'm very curious to see your work. You looks very competent. Would you like to mentor me?

Hello,
I resume this conversation because i need a clarification.
ottoline we said that clock speed is essential for clo and is the most important factor even above the cores.
So if i have to choose between an intel i7 10700k that start from 3,8 GHz to 5,1 in turbo boost and a
i9 10900K that starts from 3,7 GHz to 5,3 in turbo boost which ,
what would be the best choice?
The one with the highest BASE frequency or the one with the highest MAX turbo frequency?
Thanks a lot.

A CPU that has a base speed and then turbo's up is a fine choice for CLO3D as the turbo boost will kick in automatically as you work when it's needed > the Finer beauty pass simulation and animation in CLO3D for final work is where this will be 'crucially' needed most, so take the latter turbo boost value (higher value- 5.3 GHz) as your max CPU 'operational' working speed when simulating cloth with the CPU in CLO3D, so in that case the i9 chipset looks a slightly better spec all around, albeit at a higher price point.
You also have to keep in mind that a chipset will not just be used for MD in isolation, as you are very likely to cross over with image editing and texture creation, and other daily computer tasks along with rendering vray or other apps you may use, so when choosing which chipsets to use you need to balance out everything in concert with each other around your own daily or projected future hardware tasks.
For example I do a lot of CG and product engineering, so I need a great GPU graphics card to load big scenes, and lots of RAM as I may need a few applications open in parallel as I work. And because I do a lot of collision based simulation (as my daily task might include finite analysis) I err towards a high clock speed on my CPU as more important to other aspects of my CG work. And I often split CPU cores and allocate them to different apps I may have open, so a few more cores if you know how to manage compute resources with other collision apps open is handy to allocate, as in the case with the i9.
Each person will differ in how they need to gear their hardware, however the i9 that turbos up to 5.3 GHz should be a great choice for CLO3D out of the two.
One thing to stress with CLO3d is that workflow (how you work on a project) is also one of the single biggest speed improvements you can make (outside of hardware and that is 100% free), so 'good' work habits go hand-in-hand with a high speed chipset. I often see designers 'play' with their workflow to such an extent they are chewing through the available compute resources they have spent a lot of money acquiring, so it's also a crucial step in upgrade to recognize you also need great work habits when using CLO3D, as you could shave off huge chunks of time by simply working smarter. So buy a new chipset but also use this step as also an opportunity to upgrade your workflow - they go hand-in-hand. If you want some great tips on this just yell out in the forum. As there are many do's and don'ts when working that can knock off 20% or more on project build times.
When doing general drafting work and generally arranging the garment in place and sewing the GPU mode is great as you don't need the quality of the final cloth beauty pass when in that work mode so also ensure you consider the graphics card GPU in the context of wider workstation use for any additional CG tasks you are going to carry out, eg: drafting edits, laying out and styling arrangements, 2D graphics work or additional rendering externally with other apps (eg: post processing work), or other software related needs. eg: textures. However for that all important final high quality 'beauty simulation' with CLO3D the CPU is king, and the i9 is a sweet choice.

Hi ottoline, thanks you so much for your all useful sharing above!
I'm newbie here and want to find a new laptop for my job. I use Photoshop for Fashion design and use Adobe Illustrator for technical sketch. I usually run Clo3D with one of them or Chrome at the same time.
Could you recommend me a laptop to run them smoothly and fast, especially Clo. Or recommend me a suitable CPU and GPU, I will find them myself!
Following your sharing above, I found some CPU, but the higher Clock speed is, the less Core they have, so what should I choose? How many core does Clo need to run efficiently?
And someone said that Clock speed is just a marketing trick, we should check real benchmark to choose, is that right? If it's right, please tell me which one I should check, Multi-core benchmark or Single-core one?
GPU: RTX or Quadro RTX is better for CLo?
Thanks so much for your help
