Introduction

Photoshop is an application that tends to favor lower core count CPUs that run at a higher operating frequency, so the new CPUs from both AMD (Ryzen 7) and Intel (Skylake-X) with six or more cores are not really all that interesting for pure Photoshop users. However, there are a lot of people that utilize Photoshop as a secondary application in their workflow so we decided to take the time to see how these CPUs actually perform in Photoshop.

In addition to the Skylake-X CPUs, Intel has also launched the Kaby Lake-X Core i7 7740X and the Core i5 7640X. These CPUs are essentially the same as the existing Core i7 7700K and Core i5 7600K, only moved onto the X299 platform. These CPUs drop support for onboard graphics, but they do sport a small increase in frequency and support faster RAM. Because of this, we are very interested to see if there is a noticeable performance gain to using the i7 7740X over the current leader in Photoshop performance: the Intel Core i7 7700K Quad Core.

To see how these new CPUs compare, we tested how long it took to complete a wide range of tasks in Photoshop including:

  1. Launching Photoshop
  2. Opening/Saving large .PSD files
  3. Convert to CMYK/RGB
  4. Applying Blurs
  5. Noise Reduction
  6. Camera RAW Filter
  7. Resizing images
  8. Creating Panorama image
  9. Creating HDR image
  10. More - see full list in the Benchmark Results section

If you would like to skip over our test setup and individual benchmarks, feel free to jump right to the conclusion section.

Test Setup

Since the new processors include two different CPU architectures, our testing platform is less straightforward than normal. Most of the new CPUs support DDR4-2666 RAM, although the Intel Core i7 7740X (Kaby Lake-X) CPU only supports four sticks of RAM rather than eight. In addition, the Intel Core i7 7800X (Skylake-X) only supports DDR4-2400 RAM for some odd reason. We opted to test with the highest officially supported RAM configuration for each CPU, so components used in our X299 test platform requires an entire table just for itself:

To act as a comparison to the new CPUs, we will also be testing AMD's Ryzen 7 1700X/1800X CPUs as well as the Intel Core i7 7700K (Kaby Lake) and Intel Core i7 6850K/6900K/6950X (Broadwell-E) CPUs. Again, we will be testing with the best officially supported RAM configuration for each CPU.

Inconsistent RAM aside, one thing we do want to point out is how much more affordable the Skylake-X CPUs are compared to the previous generation Broadwell-E CPUs. Where a six core CPU from Intel used to cost over $600, you can now purchase an eight core CPU for roughly the same cost. In fact, the i7 7800X is even a hair less expensive than AMD's Ryzen 7 CPUs. This means that regardless of any performance gains we may see, Skylake-X is at the very least a big deal in terms of cost.

Benchmark Results

Due to the sheer number of actions we tested and the fact that the performance differences were remarkably consistent, we are going to forego our typical action-by-action breakdown. Feel free to analyze the individual results below in more detail if you wish, but due to the consistency of the results, we encourage you to skip straight to our conclusion for our benchmark analysis.

Conclusion

Photoshop Skylake-X 7900X 7820X 7800X Kaby Lake-X 7740X Overall Benchmark Results

To analyze the results, we first normalizing them to the Core i7 6850K 6 core CPU, then averaged the results based on whether the task was for HDR creation, Photomerge, or if it was just a general Photoshop action. We could have normalized to any of our test CPUs, but we chose the Core i7 6850K largely because this is what we used in our Premiere Pro and Lightroom testing. This will make it much easier to compare results across each article for those that want to compare across multiple software packages.

Looking at the final results, there are not too many surprises to be found. For the Skylake-X 6-10 core CPUs, if you simply compare the new CPUs to the ones from the previous generation that have similar core counts, the new CPUs are not all that exciting. They are certainly more affordable, but the 8 and 10 core are only slightly faster than the previous generation and the Core i7 7800X 6 core was actually a bit slower than the i7 6850K.

The Core i7 7820X and 7900X may be relevant for video editors that utilize Photoshop in a secondary role, but for pure Photoshop users the only interesting new CPU is the Core i7 7740X 4 core. Before today, the Intel Core i7 7700K has been our primary recommendation for Photoshop users since it gives a great balance of performance across most tasks, but the new i7 7740X is about 6-10% faster than the i7 7700K at the exact same CPU price point. You will end up spending a bit more money on the system overall since X299 motherboards are more expensive than Z270 boards, but the cost difference for boards with similar features is usually only about $60-100. So for a relatively modest increase in price, you get a fairly decent 6-10% gain in performance. That may not be enough of a difference to prompt a system upgrade if you are already using a Core i7 7700K, but if you have a system that is more than a few years old you are likely looking at a pretty significant increase in performance with the Core i7 7740X.

Very interesting read. Thanks for sharing this information! One thing that confuses me the most about this new line of cpu's is the thing about lanes and memory. I am basically interested in investing into a rig that can be upgraded. So investing into the X299 seems the right thing. But as I see it now, and that's my concern/question, the 7740X supports 16 PCIe lanes and only 4 benches of memory. So with a 16x graphics card I already max out the CPU and I can only get it to 64 GB of memory. That this means I'd have to get a bad-ass motherboard, the 7740X and 64 GB of memory plus a GPU (i.e. a 1080 Ti) and then, if I want to go to 128 GB of memory and potentially a second GPU, I'd have to upgrade the CPU as well? And how is it with USB, SATA, M.2 drives and other peripherals with a CPU which has 16 lanes that are used up by the GPU? Or does the chip-set handle those lanes? Or do I get something completely wrong here?

Posted on 2017-07-06 01:19:07

You are mostly right on everything, including that if you want more than 64GB of RAM in the future you would need to upgrade to one of the 6+ core CPUs. The only bit of information it looks like you might be overlooking is that there are a number of PCI-E lanes available through the chipset in addition to the lanes on the CPU. So while the i7 7740X only has 16 PCI-E lanes itself, there are another 20-24 PCI-E lanes available through the X299 chipset. Typically, the CPU's lanes are reserved for GPUs or other high-bandwidth devices while the chipset lanes are used for things like the SATA controller, NIC, M.2, and often a number of the smaller x1 or x4 PCI-E slots on the motherboard.

We are still in the process of qualifying different X299 boards to determine what will make it into our product line, but we are strongly considering only offering the i7 7740X in our mATX systems by default. The reason is that mATX boards already only have 4 RAM slots and only 2-3 effective PCI-E slots. So in the mATX form factor, you really are not giving up that much compared to the higher core count CPUs that have a higher RAM capacity and PCI-E count.

Matt, thanks fo shedding some light on this. It slowly get's more clear what to make of this new series of CPU's. I am curious to start hearing about the Coffe

"In fact, the i7 7820X is even a hair less expensive than AMD's Ryzen 7 CPUs." I believe the most expensive Ryzen CPU is $499 vs the i7-7820X $599

Thanks for pointing out that typo, we have corrected it to say "7800X" instead of "7820X".

Could you guys do an article or blog on Adobe Bridge an optimization? I use Bridge since it's the universal media browser for Adobe products. It's still completely relevant in my and many other peoples' workflows. I don't like depending on Lightroom's DAM (or any other DAM) because I've been burned by corrupt databases, crash appy applications(C1P), delete after import(C1P, iPhoto), and management of files when I want to and or upload them (LR,C1P,Aperture,iPhoto).

I use multiple computers to access my Assets in multiple folders and I have an easy to follow file structure (sorted by date and name) but the biggest issue isn't "where's my sh*t", but instead it's the fact that bridge decides to rebuild the cache every time I access the same folder from another computer. I have identical settings for bridge cc on each computer but when I switch computers every couple days cache rebuilds and it's super slow too.

I'm using Synology DS with 5 drives 3TB drives accessing folders w/ 1000-2000 raw files (weddings) and then folders with video files (hundreds), video projects, after effects, illustrator, psds, etc. I can almost deal w/ the slowness of rebuilding the cache, but the UI is incredibly slow as well. It seems like UIs from 2005 were much snappier than they are now. When Adobe CS was first published, Bridge was able to manage 6mb raw files with ease on a Pentium M Laptop. Over a decade later with a system with 32GB RAM, 4 Cores w/ HT, and 4.50ghz boost, running only SSDs and a 12 TB RAID 5 NAS, life seems to still suck.

Can you please do this with a decent ram speed on ryzen?! We know ryzen benefits from fast ram, and then you pair it with horrible slow 2400mhz ram

I don't understand why people posting this idiocies doesn't get a ban...

Posted on 2017-10-04 10:51:17

Unless things start to dissolve into arguments and name calling rather than discussions, we tend to be pretty light on moderating the comments. Higher speed RAM with Ryzen is a completely valid concern and the stability and reliability issues are things are often not considered by many users.

pillybilly

i understand your opinion but it's hard to find a serious site for professional nowadays, every site it's kid oriented. It's pretty boring to read every articles ryzen it's better with 3200 memories because at 3200 you need a single rank 8gb memory and with max 2 slots = 16Gb of max installed memory.
Overall 3200 memories are pretty expensive and it's pretty stupid to use it to reach 5fps in game, in cinebench you don't get any improvement.

Дмитрий

You don't need it. I'm running dual rank 3200 kit with 14-13-13-13-26-40 timings and have 32 gb of it.
Friend of mine have 8x4gb single rank kit running on 3200. I know a few people running 64gb on 3200 using DR kits. And I even know one guy that sits on 3333 but with a bit higher timings and latency than mine. And you have improvements even in synthetic tests. So there is no point in your comment. As for the stability it passes literally all the memory tests and the AMD edition Linx. And as for the games it's not the "5 fps" difference, it is more than 15 in some titles

Very interesting, thanks! According to www.cpubenchmark.net, i9-7900X is 83% faster than i7-7740X in multithreaded benchmarks. So it looks like Photoshop can only leverage at most 4 cores right?

According to www.cpubenchmark.net again, i7-7740X is 5% faster than i9-7900X in single threaded benchmarks. A cross-multiplication involving cpubenchmark single threaded scores, your average CPU performance scores, and i9-7900X turbo multipliers even suggests that only 2 cores are actually used by Photoshop. Is it possible?

Honestly I would be very curious to know how a Core i3-7350K would perform in your benchmark.

Hi There

I was just wondering if you guys will know if in future, programs like Lightroom and Photoshop will use multi-cores more or just rely on more GPU going forward, as I am upgrading from a i5 6500 with a R9 380x GPU and looking at the specs if it necessary to spend money on the X chips ... btw the 7800x is where my budget is ... so i am considering the following : 7700k, 7740x, 7800x

Posted on 2017-09-20 18:27:01

I can't say for sure where Adobe is going to head in terms of hardware usage, but we will have some more articles coming in the next few weeks that look at this year's processors. It may be worth waiting to see what the results of those look like before you decide :)

It seems that lintel i7 works better than Ryzen 7 at is it. Wondering that is it same for intel i5 7600K ( 4 core - 4 threads) vs Ryzen 1600 or 1500 (4 core - 8 threads)..? Simply is it better to go with inlet over Ryzen..?
