Introduction

If you are in the market for a new Photoshop workstation, you might be a bit overwhelmed by the hundreds or thousands of different hardware components you can choose from. Even if you are just trying to decide on a CPU, it can still be daunting to find one that not only fits your budget, but will also give you the best performance for your dollar.

In this article, we are going to be benchmarking a wide range of processors from Intel and AMD including the Intel 9th Gen, Intel X-series, AMD Ryzen 2nd Gen, and AMD Threadripper 2nd Gen CPU lineups. In addition, we will be comparing them to a current Mac Pro 12 Core and iMac Pro 14 Core for those that are considering going with a Mac-based workstation rather than a PC.

One thing to note is that we will not be including results for any previous-gen CPUs in this article. At first, we were going to include them but the charts and tables soon got out of hand. Instead, if you want to know how these CPUs compare to previous generations, we recommend checking out the following articles:

If you would like to skip over our test setup and benchmark result/analysis sections, feel free to jump right to the Conclusion section.

For the testing itself, we will be using Photoshop CC 2019 (ver. 20.0.0) along with version 18.10 of our Puget Systems Photoshop CC Benchmark which is currently available for public download. This benchmark tests a range of general tasks (open/save, resize, content aware fill, etc.), filters, as well as panorama photomerge. Full details on the benchmark are available on the benchmark download page.

Benchmark Results

While our benchmark presents various scores based on the performance of each type of task, we also wanted to provide the individual results in case there is a specific task someone may be interested in. Feel free to skip to the next section for our analysis of these results.

Benchmark Analysis

Photoshop CC 2019 Benchmark CPU Roundup - Intel 9th Gen, Intel X-series, AMD Threadripper 2nd Gen, AMD Ryzen 2nd Gen, Apple Mac Pro, Apple iMac Pro

Our Photoshop benchmark (which is available for public download) tests a large number of tasks that we split into 4 categories: General, Filter, Photomerge, as well as GPU-accelerated which contains results from both the general and filter tests. With the exception of Photomerge, we also run each test in both 8 bits/channel and 16 bits/channel mode. These results all combine into a single "Overall Score" that represents the overall performance of the system in Photoshop.

If we sort by the overall score, you can see that the Intel 9th Gen CPUs like the Core i9 9900K and Core i7 9700K are the top performers - which is to be expected since Photoshop is not terribly effective at leveraging higher core count CPUs. Next is the iMac Pro 14 Core, followed by the whole slew of Intel X-series processors that were recently released. These X-series CPUs are around 10-15% slower than the Intel Core i9 9900K depending on which model you choose.

Below the Intel X-series are the AMD Ryzen 7 and the AMD Threadripper CPUs. Interestingly enough, while the lower-end Threadripper CPUs are only about 20% slower than the i9 9900K, the two "WX" series models are closer to 27% slower. These models are essentially two CPUs crammed onto a single die which results in additional overhead that can cause performance loss in applications that cannot take advantage of higher core counts. Even with the new "Dynamic Local Mode" feature enabled (which is supposed to assist in this sort of workload) the WX models clearly have some performance issues.

At the very bottom of our list is the old (but somehow still current) Mac Pro. With the Mac Pro, we are about 30% slower than the i9 9900K.

Intel vs AMD vs Mac for Photoshop CC 2019

For Photoshop CC 2019, there is no question that the Intel 9th Gen CPUs are currently the fastest processors available. Even if you were to spend 50% more on a workstation based around an Intel X-series CPU or almost twice as much for an iMac Pro, a Core i9 9900K will still be 7-15% faster.

Compared to an AMD Threadripper system, the performance gap is even larger. Here, you can expect a Core i9 9900K to be anywhere from 20% to almost 30% faster in Photoshop. The AMD Ryzen 7 2700X, on the other hand, does about right for its price. It is a bit more expensive than the Intel Core i5 9600K, but it is also faster by a few percent. This means that if your budget can only accommodate a ~$300 CPU, you likely won't see much of a difference between Intel and AMD for Photoshop.

If you are curious how your current system compares to any of these processors, we recommend downloading and running our Photoshop CC Benchmark which is the exact benchmark used in our hardware articles. And if you are interested in how the latest Intel and AMD processors perform in other applications, be sure to check out our recent Processor articles as we have a number of articles looking at CPU performance in Lightroom, After Effects, Premiere Pro, DaVinci Resolve, and many other software packages.

I notice that both in this test and the AE test the 9960x does a quite better job than the 9940x. Is this because it has a single core speed boost that's the same as 9940x. Meaning that any single thread performance (responsiveness etc) is roughly the same but utilize the extra two cores? Based on the chart, that shows each test, it seems that the 9960x does a better job in general, even on things like rotate, which is weird, as I thought those aren't multithreaded tasks. Could it be that the 9960x just basically is a better tuned CPU, since they have the same clock boost, same wattage drain despite 9960x having two more cores?

last year 7940x scored better than 9760x - So this time around it seems adding the extra two cores doesn't sacrifice performance, in fact it only seem to benefit from it? Since the 9980xe does even better with 18 cores!

Hmm, I think I misread the chart, I thought the numbers were seconds on each of the benchmarkings except overall score. But looking at 2950x and Mac Pro, it seems its all scores. So then as assumed, the 9940x and 9960x does pretty much the same in Single threaded tasks, but 9960x gains some extra scores because of the extra 2 cores.

To be honest, the difference in this test and the Ae tests was only about 3% on average which I would really consider to be within the margin of error for these tests. So I think in most situations, you really are not going to notice much of a difference between the two processors. From the i9 9900X on up, all the new X-series CPUs have a max Turbo Boost 3.0 speed of 4.5GHz - which is what the CPU should run at with up to two cores being loaded. Since most things in Ae and Ps are only going to use a handful of cores, it makes sense that all those CPus are going to perform within a few percent of each other.

Yeah but this is in fact quite good news for those of us that needs a lot of cores, I think. Because, like myself, I got a threadripper 1950x, and was shocked by the performance drop in Adobe programs. And the same problem seemed to occur on the 79--x series as well, that the more cores you added the worse it would perform in Adobe programs (though not as severe as the AMD HEDT CPUs) But this year, it seems the turboboost is the same across all CPUs, so if one need more cores, one can choose pretty much the amount of cores on the Intel X series as one would like without loosing any performance in AE or Photoshop.

The Turbo Boost 3.0 change is definitely the biggest advantage to these new X-series CPUs. Performance-wise they are only moderately faster than the previous generation, but it is really nice to not have to decide between higher single-core performance or higher multi-core performance. You really just go higher up the stack if you need higher multi-core and don't worry about single-core performance. Really, really nice especially for system integrators like us.

Yes, exactly what I would wish for :) I don't care what people say about AMD giving more cores for the money. When you work on these machines every day, this is what it all comes down to, performance on both single and multiple cores.
When you are testing this, are you setting up the programs as priority through the turboboost 3.0 program, or does the machine manage this automatically ?

Posted on 2018-12-10 19:12:54

Turbo Boost 3.0 priority is BIOS level these days actually (unless you have it in "legacy" mode in the BIOS). So core prioritization is all done automatically.

Oh so you do not need the annoying Turboboost software at all then?

Posted on 2018-12-10 20:36:16

Nope! Not as long as your motherboard supports the newer "Native" mode which I would be surprised if any X299 boards don't at this point.

Fascinating that the 14 core imac pro beats out the 14 core i9 windows. Makes you wonder what Apple computers could do if they kept their chips up to date...

You are comparing an x processor to a Xeon. You would have to see the test with an equivalent Xeon to know if the Mac was really faster. There are subtle differences between x processors and Xeons that sometimes make a big difference depending on the software. Not defending any OS here, just noting the difference between processors.

Posted on 2018-12-08 18:53:28

I don't think it is actually Xeon vs Core that is making the difference since these days, the two lines are really the same in terms of performance. Compared to the Core line, the main advantage with a Xeon CPU is that they have support for Registered ECC memory (allowing for up to 256GB configurations), have slightly higher Turbo Boost clocks (although they don't have Turbo Boost 3.0 so in the end it doesn't tend to make much difference), and they are supposedly binned better so they should be a bit more reliable (although both fail so rarely is is hard to tell if this is true).

I think the main reason the 14 core iMac Pro performs better than the i9 9940X on Windows is simply that MacOS is a slimmer and more efficient operating system. Of course, you are paying a hefty premium for that OS (unless you want to get into a Hackintosh setup), so with a PC you can get an even faster CPU to overcome the OS differences. Or faster storage, more RAM, multiple displays, etc. while still coming in at a lower price point than the iMac Pro.
