Title: Which CPU and how much RAM for Photoshop in 2018?
Post by: stevierose on October 30, 2018, 08:07:21 pm
I'm not sure if this should go in the computer section or Photoshop section, but as I am interested in input from folks who use Photoshop a lot I will put it here. Today they announced the new Mac Mini. This is good news for me because I have a high quality dedicated monitor so didn't want an iMac and can't justify a Mac Pro. My question is this--which CPU and how much RAM do I need to easily do photo editing with the latest software versions? I use Lightroom, Photoshop, and various plug-ins. I shoot RAW with APS and occasionally full frame sensors. I don't shoot MF digital. I also shoot film which I scan. I print to an Epson 800. The CPU choices include a 3.6 Ghz quad core 8th generation Intel i3, 3.2 GHz 6 core i7, 3.0 Ghz 6 core i5 with turbo boost, and a 3.2 Ghz i7 with turbo boost. I don't do any significant amount of video editing. I am willing to spend what I need to configure a good photo editing computer but don't want to waste money buying power I don't need. What do you folks think I should get?

Thanks

I’d avoid the i3, a budget processor, some say they’re i5s that didn’t pass certain benchmarks. This is the first time Apple have used them. The rest should cope fine. Obviously, you pay for what you get, move up the scale and things get faster.  The GPU is the other factor to consider.

Hi Steve,

Here's another approach to try perhaps.  LuLa is a great forum and one that I frequent daily, but when it comes to questions such as you have raised I would suggest two other forums as well.  The Apple forum and the Adobe Photoshop forum.  Both have some very knowledgeable people waiting to answer your questions and offer some very viable suggestions.  I would try the Apple forum first, since your quest is to put together a hardware package that would do the best job for your purposes.  Give them a try and report back if possible.

Hi Steve,

The tests are done under Windows PCs, but Pudget system evaluates a lot of systems with Lightroom and Photoshop benchmarks and they evaluated the new processors that come in the Mac Mini (that are not new... basically those processors have been available in the market more than one year ago):

- https://www.pugetsystems.com/labs/articles/Photoshop-CC-2017-1-1-CPU-Performance-Core-i7-8700K-i5-8600K-i3-8350K-1057/

The new version of Photoshop, the 2018, they have only evaluated using the latests Intel or AMD processors: https://www.pugetsystems.com/labs/articles/Photoshop-CC-2018-Core-i7-9700K-i9-9900K-Performance-1248/ , so not useful for you.

Maybe that tests can give you and idea of what you want.

Regards,

David

I've been using PS 2018/2019 on a Powerspec Win10 system with: i7-8700k, 32GB DDR4 3200 RAM and a GSX 1070 11 GB DDR5 display adapter and SSDs for system and scratch. I have been very happy with the performance handling 51 MP files with lots of layers, 3-5 raw image HDR merges, etc... Very snappy responsive system.

I choose the 10 core i9 - ( it has more cores and more (44) PCI lines)
the extra PCI lanes are handy for NVME memory support that uses 3lanes- and the GPU already 16...
it runs At 4.5 GHZ with watercooling and does 1800% work with LR 7.5  - 35- 40 nef d850 /minute to 16 bit tiff.
Photoshop uses less cores - not optimized since 19..? 6 cores will do.
5600 one core and 40.000 10 core - benchmark geekbench 4.2
32 GIG ram is enough for almost all cases ( i work with images of 10 GB)

well, it’s all a matter of what’s acceptable.  For most tasks photoshop does just fine on average hardware. but there are those things that pop up a progress bar and you can do nothing but wait. Obviously if there is one thing that you do a lot and it takes a considerable amount of time on a quad core i5, and if it runs 15-30% faster on a 6 core i7, then maybe it’s worth it?  Hard to say but you really can’t get too much power, its usually about getting enough to make you happy and still fit your budget. I know I bought a MacBook Pro a few years ago, and immediately regretted it just because even if the model above it was only a little faster I felt it was worth it.  Sold it and bought the top of the line. So if it were me I’d go ahead and spring for the 6 core i7.  Only $200 more than the 6 core i5.  The small clock speed gain is minimal, but hey, every cycle counts. 

However if you are willing to wait a while, Digiloyd at macperformanceguide.com has a very good test he calls photoshop huge and it’s a pretty good way to benchmark PS performance on various Macs.  Not sure if he’ll test the Mac mini but he might.  Also I just read over there that the MacMini is upgradeable so it might pay to buy the minimum ram from apple and then upgrade to 32 or more with OWC memory.  That’s usually a cheaper route.

Photoshop is not particularly efficient at using many CPU cores. For example, I tried running Photoshop on our primary server we use for building profiles (4X 14-core Xeon, 256 GB memory, 2X Tesla graphics cards). Until file sizes got huge, Photoshop was if anything less responsive than on my XPS 13 laptop with a single Core i7.

More than 6 cores gives diminishing returns for your money. I would budget stuffing your system with memory and a decent-sized, fast NVMe SSD. Add a video card that is capable but not top-end (e.g. Nvidia 1070) if you plan on using GPU accelerated plug-ins such as those from Topaz.

All this assumes you are not working with 100+ MB, full-frame medium format captures. If so, you'll likely want something other than Photoshop for processing RAWs. Beefier systems are in order here.

To speed up photoshop:

fast cpu- 6 core
enough RAM 16gb ram( enough for not too big images as stated)
and fast harddisk...
the latter could be a 970 samsung  pci  ( 2500mb/sec) or cheaper/larger a normal SSD ( 500mb/sec)-
GPU not that important.

Only important to the extent you want it to support the monitor you want to get. You don't want to buy that 5K monitor only to learn your GPU won't support it.

[GPU is] Only important to the extent you want it to support the monitor you want to get. You don't want to buy that 5K monitor only to learn your GPU won't support it.

I recently upgraded my desktop machine with a 1070 Ti to run A.I. Gigapixel.  Works fine with my 2+ megapixel 1920x1200 24" monitor and my ~3.6 megapixel 2560x1440 27" monitor.  Then I started hankering for a 32 megapixel 8K monitor (https://www.bhphotovideo.com/c/product/1324922-REG/dell_up3218k_ultrasharp_32_ultra.html) (when they come down in price) only to find that I'd need a 1080 to run 8K.  The 1080 was about $30 more than the 1070 Ti.

96 megapixel images (2X 24 megapixels) created by A.I. Gigapixel are difficult to evaluate on a 2 megapixel 24" monitor.  It is difficult to determine if "plausible" detail is really plausible when it will be viewed on a >300 PPI medium (large print...)  My 8 megapixel 4K 14" laptop is 320 PPI but is only about 12" x 7".

Megapixels need GPU.

Depends on your photoshop preferences too.  If you do big layer stacks with light painted images, composites, etc... and file sizes of psd files are in the gigabyte range...more power is nice. 

I just upgraded to an i7 Mac mini.  I  went 64gb ram and a vega 64 video card...but that is probably overkill.  A decent video card will be plenty...but I would go with at least 24gb of ram.  I would never choose an i5 if I did a lot of work on it.  I made that mistake with my laptop.  The i7 just always feels snappier with larger files.  Regardless everything feels nice and efficient again.  Especially Lightroom.

I have an Intel six core i7 for processor, 32gb DDR4, and a Radeon RX570 video card with 4gb memory.  All of this is probably way overkill for photo software, but I got a great deal on it from my son, who bought a much bigger computer last summer.  He's a video game programmer for MicroSoft.  I think the most important thing is to get a graphics capable monitor of one sort or another.

Intel just has launched a new processor line

my favourite is

Core i7-9800X    Skylake-X    8/16    3,8 / 4,4 / 4,5GHz    16,5MB    44lanes    ddr4-2400    140W    $589

8 core - 44 lanes  4.5 GHZ
would be perfect for photoshop/LR

According to my knowledge, Ps and Lr uses most of the CPU rather than the GPU (CUDA). Something like the new AMD with 24 threads would be a great tool to run something hardcore.
But, even tho AMD has a lower price when it comes to C/P (cost over performance), I still personally prefer intel. I am actually planning to build an intel i9 machine after the Chinese New Year and hope that machine could serves me well in the next 5-8 years.

If you want to test it yourself:
https://www.pugetsystems.com/labs/articles/Puget-Systems-Adobe-Photoshop-CC-Benchmark-1132/


I have no connection to Puget Systems, nor do I want to promote their products, however, the benchmark is a great tool and their test of various systems is a great guideline.

I currently run two systems:
i9-9900k with 64GB - NV RTX 2070
i9-7920X with 128GB - NV RTX 2070

For Photoshop the "cheaper" 9900k is faster as long as memory doesn't run out. For C1, PtGui and Lightroom the 7920X is faster. However, for C1 and a lot of Photoshop filters and plugins, the GPU is more and more important. While I like what AMD is doing, they don't get close when it comes to PS performance.

The i9-9900k while very fast has only 16 PCI lanes- that means no lanes are available after you have connected your GPU.
And you need more lanes for PCI; fast memory, like the samsung 970 evo is connected through a 4 lane pci-interface.
This type of memory - it does 2500mb/sec-  is a vital part of the speed of your system as a whole.

While it’s true it has only 16 lanes from the CPU you still have the 4 from the main board to cpu which handle a 970 evo just fine.

I use one 970evo and the rest sata SSDs on the 9900k and on the other system two 970 pro 2tb. In all honestly, when something takes longer, like a complicated filter the ssd isn’t at fault.

In addition one has to remember that even a RTX 2080 Ti has only very slight performance increase by using 16 vs 8 pci.


In capture one for example I can use 2 x 2070 at pci 8 and still get around twice the performance. ( compared to PS, C1 actually uses and scales nicely with more GPUs)

That is not my experience... filters are CPU restricted i agree, but my photography/workflow is probably different:
I have to open, deal with and save many GB panorama's or change hundreds of nefs into 16 bit tifs.
-
Have no experience with Capture-one- i use LR, but i can imagine C1 is soo much faster if it uses the GPU-potential.
LR and photoshop uses the GPU hardly to none.. A fast GPU for LR/PS is wasted money, at least at the moment.

Post by: Christopher on November 30, 2018, 08:08:04 am
Well, I only work with large files. And as I shoot mainly panoramic images processing speed is the most important part for me. That's also the reason why I don't bother with LR anymore except for DAM capabilities.

As I use a PCIe SSD as main working drive I never had a speed problem when opening and saving, I can also say I don't notice any difference between both PCs.



Just as a reference:

200 GFX raw files converted to 16bit TIFF files to a PCIe SSD and normal SATA SSD

Lightroom uses 100% CPU and takes 7:45 same time to the SATA drive

Capture One with one RTX 2070 3:12 and 1:58 with two RTX 2070. Difference between PCIe and SATA drive is around 30 seconds.

Opening and saving files in PS is certainly faster on a fast SSD, however, I get most time-saving at raw processing.

OK good to know !

i will have a look at C1 version 12- have a modest GPU...
And i use LR complete the opposite: only for nef to tiff...
a central damm does not work for me...
yes LR CC uses the CPU to the limit... unlike version 6

Actually it depends. Sometimes it’s just 20raws to concert sometimes a few thousand.

So speed is often very important.

These days the GPU is becoming the most important thing in photo editing with the latst programs fronm Topaz really needing at least a mid range GPU to run properly.

I have a Z800 with 2 Zeon 5690 processors and 96GB RAM which kicks the crap out of most i7s when using all cores but I've recently installed a GeForce 1050Ti 4GB to run the Topaz programs in a reasonable time.

So a gaming PC with a good GPU could cope well since the GPU usually only uses 1 or 2 cores of the CPU.

I too am possibly interested in the 2018 Mac Mini and have wondered about configurations. It's not at all clear to me though that most of those who kindly responded to this post are aware that the new Mac Mini is not available with a separate video card. It has an Intel UHD Graphics 630. I'm surely not as computer sophisticated as some of the posters but as I understand it to add a video card to the mini, one must use an outboard card with a separate chassis. There appears to be debate about whether a separate video card is really necessary.

Lloyd Chambers says it's important for video but downplays the need for Photoshop and LR, I think, somewhere in his review, I believe
. I'd love to hear some opinions from the experts who've responded on the question of the OP re which CPU and whether the extra $500 or so for an outboard video card is with it.

I use a Microsoft Surface Pro 6 for traveling and it has Intel 620 graphics.  It is certainly capable of processing files in C1, PS, etc, even from medium format cameras, albeit sometimes a bit slow on graphic intensive tasks compared to my i7 workstation with nVidia 1080 graphics.  The biggest problem with this approach is that Intel 620 or 630 or really any Intel embedded graphics is that it doesn't have it's own RAM for the image processing engine and has to borrow it from main system RAM, thereby reducing the amount of RAM available for other tasks including image editing.  The more memory you can stuff into the Mac Mini, the less of an issue this will be though.

As you use  latest Adobe Photoshop, Lightroom software and various plug-ins for post production tasks, you should use PC of High configuration to perform your work smoothly and efficiently. In this respect, you should have minimum 8th generation core i7 processor(3.80 GHz), 16 GB RAM, 1 terabyte Hard Drive Disk. And I think you can purchase this config Photo Editing PC at an affordable budget.
