#1. The GPU uses OpenGL and Open CL but the latter is not as essential and not every card can run it. Photoshop does not use CUDA, but some video programs like Premier Pro do. OpenGL is essential for full use of CS6 and CC. See this link for GL and CL features. http://forums.adobe.com/thread/979969
Onboard GPU will work in normal situations, but the real key is the driver. ATI and nVidia have more frequent updates.
See this site for GPU. Try to get score near 1000. Over that you may pay more than you gain in speed. http://www.videocardbenchmark.net/
Hope this helps lower the confusion index.
Thanks for the links Curt. The Adobe FAQ link confirms for me that a GPU is a very useful and needed component for Photoshop. I don't understand why people on forums are going around suggesting that you don't need a GPU unless you are doing photo editing. Seems like incorrect advice to me.
Given that a graphics card is needed and the fact that the Mercury Graphics Engine is using OpenGL and OpenCL (and not CUDA), any thoughts on this question that I had:
it better to get the AMD cards (Radeon most likely) that seem to completely outperform the GeForce cards in OpenCL at least?
From looking at the results on http://clbenchmark.com/ it seems like the best thing to do is get a AMD graphics card.
Anybody else agree/disagree? Anybody hear about the fact that OpenCL is disabled/stymied in the GTX 6xxM and 7xxM series cards? Is there a hack to enable it?
Any thoughts on the display question - IPS vs TN?
Having said that Photoshop with its use of Open GL and its Mercury Graphics Engine, is different to Premiere Pro which uses CUDA for its Mercury Playback Engine, I'd still have a look at sites like ADK and VideoGuys where they specialise in making hardware for PremPro, including custom laptops.
There's a spec list here
And some recommendations from Videoguys HERE
Something else I have noticed is that Scott Kelby and ‘The Photoshop Guys’ over on Kelby TV, all seem to use Mac Book Pros, and I understand that for most of them, it’s the only computer they own.
I am looking for a laptop right now, but I want it to run most of the Creative Cloud apps, and after looking into it for a couple of weeks now, I still feel a long way off from committing dollars to a decision.
[EDIT] Just read the VideoGuys link again, and I see the Mac Book Pro is their number one choice. Hmmmm...
Dennis, thanks for the thoughts. I am looking for a laptop for image editing and not video editing. So don't need PremierePro or video editing capabilities. That said, from my research PremierePro also seems to be moving aggresively toward OpenCL. In fact I came across an interview with the Director of Engineering for PremierePro talking about how they were preferring OpenCL and the fact that AMD's graphics engineering team is working very closely with Adobe.
I have heard that Macbook Pros are not good for photoshop work. Seems to be mainly due to the graphics card and display (yes the display - even the retina pro). Here is a comment on it from a NBR moderator that used to use Macs exclusively, but has since moved to PCs. Search for his posts on NBR. Here is one. And here is another thread that talks about overheating with the Macbook. Apparently the Macbooks are the worst when it comes to heating/cooling. Makes sense becasue of the thin profile.
After reading the Video Guys comments about the Mac Book Pro yet again, I am wondering why they were bying so positive about them.
This is what I am leaning towards at the moment. TradeMe is New Zealand's answer to eBay. This is a factory refurbished Alienware M17x R4, and the sepcs look pretty good for the money
256Gb SSD for OS and programs
1Tb HDD for data etc.
GTX 660M with 2Gb DDR5
17 inch 1920 x 1080 screen
(1x) Power/DC-in Jack
(4x) SuperSpeed USB 3.0 Ports
(1x) eSATA 3Gb/s + USB 2.0 Combo port (with PowerShare Technology)
(3x) Auto-sensing jacks for Line-out (2 line out; 1x SPDIF/Headphone)
(1x) Microphone Input jack
(1x) RJ-45 (10/100/1Gb IPv6)
(1x) HDMI-1.4 output with Audio
(1x) HDMI-1.3 input with Audio
(1x) mini-Display Port
(1x) VGA Port (DB-15)
(1x) 9-in-1 Media card reader
I can get this for NZ$3300 (US$2540)
They are heavy at 9.4lb (without PSU and case, but that wouldn't be a problem for me. They are apparently good with Photoshop because of the decent processor speed and the nVidia card.
My one concern is that they have a shiny screen. Any thoughts from anyone on this and the rest of the spec?
Hi Dennis, from what I have heard Alienware is expensive due to brandname more than anything else. They are now a Dell subsidiary. Have you tried pricing an equivalent machine by Origin/Sager (Clevo)/MSI? I think you will find them much cheaper.
Look over clbenchmark.com and compare the AMD GPU with the nVidia cards - huge difference in OpenCL.
Separately, I would much appreciate it if you took your post to a separate thread, and leave my thread open for people to reply to my questions rather than be distracted by yours.
At the potential risk of your pretending to kick me off what you misguidedly perceive as your thread—which by the way you would have no right to do, since you do not own a thread just because you started it—I'll have a couple of comments on your original thoughts.
There's no reason to be "confused" here.
1.— Utilization of the GPU is indeed always beneficial to using recent versions of Photoshop, regardless of whether you work with video or not. Whether you "need it or not" is a different discussion.
2.— Of course it's absolutely necessary to be able to work with a monitor that has a narrower gamut than your working space or even your output target profile. In my case, for example, as I'm 99.9% concerned with high quality prints, I work exclusively in ProPhoto RGB. I'd be in a pickle if I were to restrict my work to just what I can see on any monitor regardless of how wide its gamut were.
One just has to learn how to work in Photoshop. That's what Gamut Warning and Soft Proofing are there, for example. Printers are capable of printing some colors that are not visible on any monitor.
3.— If both the video card and/or its driver fail to support Open GL and Shader Model, no "hack" on Earth can make up for it.
4.— If someone came to me for advice on a laptop on which to run Photoshop well, my main and perhaps only goal would be to dissuade that person from wasting his or her money.
I know there might be flak from some laptop users for that immediately preceding paragraph, but hopefully not as much as you're likely to get—and deservedly so—from Mac Pro users for your astonishingly uninformed comments on those machines.
One thing is having a laptop as a second machine on which to show your Photoshop work to clients and prospective clients when forced to, and another one is trying to use a laptop as one's main, working Photoshop machine.
Going to a laptop publication (which I gather the obscure, niche-market "NBR" you cite is) for information on whether to use one or not is like seeking theological religious advice about world religions from the Pope in the Vatican or the Ayatollah in Tehran.
5.— In the past I had run Photoshop on a variety of different nVidia GeForce cards with up to 512 MB of VRAM, but with Photoshop CS6's more advanced utilization of the GPU I have moved to a mutant, factory-overclocked, flashed ATI Radeon HD 5770 with 1 GB of VRAM driving side-by-side dual 22" monitors in my current desktop Mac Pro 2.66 GHz under OS X Lion 10.7.5 and I couldn't possibly be happier.
I do run my second copy of Photoshop on my Mac Book (not "Pro") laptop with its stock Intel GMA 950 video circuitry and its paltry 64 MB of shared system memory, and it works just fine for the aforementioned purposes of showing Photoshop work to others. I wouldn't want to do any editing in Photoshop on that machine other than for minor touch-ups in an emergency, however.• — — —
Lastly, I feel compelled to add that, in my opinion, basic human decency would dictate that you offer Trevor some sort of apology for your presumptuousness in asking him to leave this thread. If I hadn't already begun typing this post before you posted your #6, I might have just ignored your thread. Considering the overall anti-laptop tenor of this post, you may well wish I had.
station_two, many thanks for the time in replying and your pointing out my incorrectness.
So, for saying that this is "my thread", many apologies to Trevor, and the forum at large.
That post honors you, seeingmind0. Thank you.
