Hardware recommendations

Yeah, I would have expected a bit more of a difference than that but not much. With SU my understanding is the CPU is pretty much in control of the geometry while the graphics card handles the materials and shadows. That doesn't leave a whole lot for a high end card to do. If you test it out with a large model with lots of big materials and shadows on you might see the gap widen a bit but I'm not sure offhand what the difference is between the to graphics cards.

As far as the price difference, yeah it sounds like a pretty big jump for .3 ghz of RAM. If you've got a desktop at home that you can do rendering on I'd stick to the cheaper one. But if this is your only machine maybe it's worth it to you to spend the extra money. Only thing I can say is that if you're going to spend extra money on anything with a rendering computer it should be the CPU. Adding RAM usually isn't too difficult and even upgrading graphics cards isn't so bad but upgrading CPU's is pretty tricky.

Hi to ALL,

I want to upgrade my desktop PC in the near future, especially for the use of SketchUp and high poly counts for example and for rendering purposes and for photo editing.

After some research on the Internet and in the forum, I would prefer the Intel i7 860 processor instead an i7 920, 8GB Memory (DDR3), and Windows 7 64-bit.

The graphics card I'm not sure what is the best choice for these purposes. I prefer a Nvidia graphics adapter, because I rode with them always good.

I do not know what's really important at the graphics card for the above mentioned purposes. And the many I've read on the internet has confused me even more. And the product range confused me too.

And I can't really see, what is the most important factor that influences SU's performance and the performance of render machines.

For Which type would you advise me?

Nvidia Quadro FX 580 (G96) 512MB GDDR3 / 32 CUDA Processing Cores / 2 Display Ports und 1 Dual-Link DVI-I Output
Entry-Level Productivity CAD / DCC

Nvidia Quadro FX 380 (G96)Entry-Level 256MB GDDR3 / 16 CUDA Processing Cores / 2 Dual-Link DVI-I Outputs

200 Series
GeForce GTX 295
GeForce GTX 285
GeForce GTX 280
GeForce GTX 275
GeForce GTX 260

9 Series
GeForce 9800 GX2
GeForce 9800 GTX+
GeForce 9800 GTX
GeForce 9800 GT
GeForce 9600 GT
GeForce 9600 GSO
GeForce 9500 GT
GeForce 9400 GT

Any help and advices would be very appreciated.

Unfortunately graphics cards aren't used to their full potential very often. In SU your graphics card will basically be used for your shadows and textures while geometry will be taken care of by 1 core of your processor. In most rendering engines out there your graphics card does nothing for your actual rendering times. It only helps if you have a "studio" in your rendering program that will let you rotate the model around, but once you click Render your graphics card isn't really used. So in that vein, graphics cards haven't been very crucial. You could get a pretty decent card and be fine.

HOWEVER, the next wave in rendering engines is to use the graphics card power rather than or in addition to your processor power which allows for nearly real time rendering. So if you want to think ahead towards the future you may want to buy the best card you can. Before you decide you may want to check out some of the rendering engines out there that do gpu rendering like v-ray rt. they may have some good suggestions on what they like to see in a graphics card.

Charly,

The QuadroFX cards you mention would probably work OK, but their performance is not too stellar. For a QuadroFX card, I would choose one with a 4-digit model number (and the 512 Mb graphics memory is the minimum recommended by Google, although SU seems to work OK with much less - the laptop I am writing this with has only 64 Mb). If you cannot afford that, go with a GeForce.

Anssi, I think Thom mentioned earlier in the thread that SketchUp requires more CPU power than GPU. I think this is true. Bus speed to the processor is also important, I think? My HP workstation I've had to stop using, despite it having an Nvidia 512mb card, It was a P4 (single core- XP 32bit), but ran at 3gHz or something. I've swapped to this Macbook Pro, which although is 3 years old, has a higher bus speed, and is dual-core. The GPU is an ATI X1600 with 128mb vram, and the performance is better (but is now beginning to show cracks!)

I do need a faster machine. Mac or PC, I would prefer another Mac, but it's what gets the job done for the minimum price. But then again, I've had 3 PC's go wrong on me over the last 4 years, but this (Apple) laptop is still going strong! So what's the cheapest now? Do I blow £2000 on a new Mac, or £700 on a PC that may go wrong again??

Annssi, Brodie and tfdesign, thank you for your explanations.

I have researched a bit and I think the GTX 260 seems to be more interesting for Gamers. While its Quadro FX 580 seems to be better suited for semi professionel grafic workstations.

That should not be a statement it is only a question too. For what are the bold marked points important?

I plan to be building a i7 Core 920 soon and received a handful of "hand-me-down" graphics cards which I hope you can help me decide on which ones would be best for SketchUp use;

ATI Radeon 5850
ATI FireGL v8650
ATI FireGL v7600
ATI Radeon 4850

I think the 5850 is the newest of the bunch (but it primarily for gaming) whereas the FireGL is workstation class with 2Gb of memory, but it IS 2 years old (which is an eternity by computer time!). Which would be better to use? Would I benefit from "Cross-Fire" linking of them in SketchUp? Can I cross-fire link a Radeon with a FireGL?

I hope to build the new rig with 6Gb RAM and Windows 7 64bit - anything I should be aware of as it pertains to SketchUp?

Thanks,

brodie

I can't speak to those specific model numbers but I've had both Radeon and FireGL and have run into quarky issues with SU. Some of them have been detrimental (selecting faces behind the one I selected) and some of them have only been annoyances (odd coloring of selected faces). If you browse around this thread you'll see all sorts of recommendations against ATI cards in conjunction with SketchUp.

That said, if they're free it's worth giving them a shot before you spend cold hard cash on an nVidia card. But what might end up being the determiner isn't so much which card is best but which card plays nicest with SketchUp. I'd start with whichever card is the newest and has the latest drivers unless someone speaks up who has one of these cards in particular.

I would start by trying the FireGLs. Last week I had, after being sceptical for a long time, to admit that a mobile FireGL in a Lenovo notebook seemed to work OK with SU. However, the OS was the tried and tested Windows XP 32-bit. So it is definitely a question of finding the right drivers for the OS.

As for performance, I don't think you will have any problems about that. SU is still quite CPU-oriented (and single-threaded), and any decent graphics card will do. In comparison to my old P IV notebook with mobile Geforce graphics a quad-core Xeon with a middlerange QuadroFX is noticeably, but not explosively faster, but the older one is still quite usable, at least with my small models.

I understand that linking two graphics cards only speeds up gaming (Direct3D) performance, but has no effect on OpenGL (that SU uses)

I heard the latest batch of ATI graphics cards (Radeon HD 5770 and HD 5970)have taken the long held performance crown from Nvidia. Whilst they might be gaming champs do they play nice with Sketchup? Has any early adopters had any experience? I am currently thinking about jumping the bandwagon but are worried about the old ATI driver reputation.

thomthom

I just got a new computer at work with and ATI Radeon HD 4870 X2
Powerful beast - but some graphical glitches on occasion while working with SU.

Powerful Hardware is one thing - but it doesn't help much if the software isn't to par. IMO - i still prefer nVidia as their drivers and OpenGL support seems more stable.

chango70

Cheers. I guess I will have to wait until Jan next year for the next batch of competing Nvidia GPUs (as rumors go). I wish ATI would just sort out their OpenGL driver issues.

I want my Quadro FX 3500 back....

Hi,
finally, my new PC is ready for use. I've installed all the software again. Only with the driver for the Creative Audigy sound card, there are problems. Also, some older programs can't be installed any more. Now I have to try the power the PC brings.

I have selected the following equipment:
Processor: Intel Core i7 860
Motherboard: Gigabyte GA-P55-UD3, Intel P55
RAM: 8 GB
Grafics card: XFX GeForce GTS 250 512 MB
two SATA Harddisk each 350 GB
OS: Windows 7 64-bit

The first test with Sketchup delivered the following results:

Test.SKP

Test.SKP with shadows

SU Framerate test

Good looking computer and good benchmarks there.

This might be a little late in answering but I'm almost positive you need two of the same card to use cross-fire (eg. (2) 5850 CARDS).
I'd be wary of spending a bunch of money on a workstation graphics card for SU. The only real difference between "gaming" cards and workstation cards are the drivers and the tech. support. For some programs -- 3d Studio Max, for example, the drivers make a huge difference. I haven't heard that they've been optimized for SU.
For ATI cards, the DirectX 11 seems to be useless for anything less than a 5850 as the cards aren't powerful enough to compensate for the performance hit from using dx11 instead of dx10. The 5000 series is MUCH more energy efficient but you can get more power/$ from using the 4000 series (not to mention more mature drivers). The 4890 is a very powerful card and can be had for ~$180 or so. That said, the 5850 and 5870 are very nice cards.
Recently there was an article (http://www.tomshardware.com/reviews/2d-windows-gdi,2539-11.html) about 2d (and 2.5d) graphics where the ATI cards perform VERY poorly (and the NVIDIA cards are not much better). Fixes are supposed to be in the works, but it's still worth knowing.

NVIDIA cards tend to be more expensive than ATI for comparable power although they are sometimes more stable and you need an NVIDIA card to use CUDA (having the graphics card help with general processing) in programs like Octane Render (which looks like it could be amazing).

Hopefully some of this is helpful.

DirectX performance and crossfire and related technologies are totally irrelevant in the case of SketchUp. SU uses OpenGL, not DirectX, and OpenGL does not support the multiple graphics card technologies.

I was just responding to an earlier question about whether or not you could use different types of cards for cross-fire/sli.
As for directx, I was saying that the benefits of directx 11 are useless unless you get the top level of cards. I know that SU doesn't use cross-fire or dx, but presumably the machine will be used for programs other than su. GPGPU rendering/processing is coming soon to say nothing of games
Besides, if SU is the sole reason for investing in new hardware your money would be better spent on cpu/cooling/ram or something and just getting an 8800gt video card.
