Results: DTP And Multimedia
We're often asked which CPU or graphics card is best for intensive Adobe CC workloads, and we're ready to answer the question as far as CPUs are concerned.
Once again, we leave the provisioning and automation of the benchmarks, as well as the computation of the geometrical mean (GEOMEAN), to PCMark 8 Professional.
Adobe Photoshop CC (64 Bit)
We have two different Adobe Photoshop benchmarks to run. The top of the chart stays the same, but the lower rungs change places depending on the workload. We start with the light version.
| Pictures | File Size | Picture Size | |
|---|---|---|---|
| Source | 14 | 3.9 - 17.6MB | 2500 x 1677 6048 x 4032 |
| Target | 14 | 388 - 778KB | 1200 x 800 |
| Actions | - Start Application and Load Data File - Change Color Balance - Add Auto Level - Adjust Shadows and Glare - Downscale with Bicubic Interpolation - Compute and Add Unsharp Mask - Save Results in Files and Close Application | ||
Using additional functions, which includes output in different compressed file formats, puts even more strain on the hardware. Taken together, the two tests provide a fairly complete picture of any bottlenecks that would be encountered in daily usage. The filters used here don’t include GPU acceleration, which means that we're measuring CPU and platform performance.

We don't see the usual order due to the Core i7-7700’s surprisingly bad performance. We repeated the benchmark run several times, but, for whatever reason, the result stayed the same. Still, the differences are tiny. None of the CPUs, not even AMD’s FX-9590, are actually slow.
Adobe InDesign CC (64 Bit)
Adobe InDesign emphasizes IPC throughput, as evidenced by its sensitivity to clock rate. It’s interesting that the Kaby Lake CPUs end up being slower than the corresponding Skylake models at the same frequencies.
| File Size | Pages | Pictures | |

| Actions | - Start Application and Load Data File - Change Picture Size and Reposition Pictures - Add Colored Rectangle as Decorative Element - Change Border Settings - Insert Text - Save Document as New File - Export as PDF File and Close Application | ||
Adobe Illustrator CC (64 Bit)
For Adobe Illustrator, CPU and storage performance are the deciding factors. The hardware’s particularly important when it comes to writing operations.
| Original File | Saved File | Exported PDF | |
|---|---|---|---|
| File | 733KB | 6.2MB | 5.6MB |
| Actions | - Start Application and Load Data File - Change Picture Sizes and Reposition Pictures - Add Translucent Filled Rectangle for Color Effect - Vectorize Pictures in Document - Add Text Fields, Lines, Rectangles, Ellipses, Stars and Spines - Save the Documents in a New File - Export as PDF - Close Document and Application | ||
Adobe After Effects CC
Adobe After Effects is able to schedule tasks like vector conversion in parallel. This is reflected in the results from CPUs with SMT that achieve better multi-threading performance, placing them above their competition. Uncompressed AVIs drive home the point that a higher clock rate can compensate for the lack of SMT.
| File Size | Resolution | Data Rate | Audio | |
|---|---|---|---|---|
| File 1 | 890MB | 1080p, 30 FPS | 1458 Mb/s | 1536 Kb/s 48 KHz Stereo |
| Output | AERender (Uncompressed AVI) | |||
| File 2 | 5.64MB | 1080p, 30 FPS | 0.9 Mb/s | 256 Kb/s 44 KHz Stereo |
| Output Settings | Windows Media Video 9 Advanced Profile - Constant Bitrate: 0.9 Mb/s - Image Quality: 98 - Keyframe Interval: 1 Second - Buffer Size: 1 Seconds Windows Media Audio 9.2 - Constant Audio Bitrate: 256 Kb/s, 44 KHz, Stereo (A/V) CBR | |||
Bottom Line
Adobe CC doesn’t demand a CPU with SMT at this point. In the end, any good quad-core processor will do, with the largest gains observable from high IPC throughput and clock rates. Processors that can hit even higher clock rates via Turbo Boost/Core across four cores have an advantage.
A direct comparison shows that Kaby Lake CPUs aren’t any faster than Skylake CPUs at the same clock rate. It’s actually the opposite in some situations, with the Skylake CPUs edging out Intel’s new processors. In order to achieve this, the older CPUs first need to be manually overclocked, though.

- Conclusion
Not true, i setup Kaby Lake in my lab and everything works fine under Windows 7. Did you guys even try to apply drivers for HD Graphic 630?
Bring on the new AMD cpu's!!!
Oh, nice review the boring is not Toms fault
"...Obviously we need a competitive AMD to help reinvigorate the desktop PC space."
Without real competition the only risk Intel takes with the Desktop market is to loose sight of (i.e. actively ignore) the performance jump the consumer expects in a new release. Continual and lengthy minor incremental updates (pretty much what we've seen since the 2000 series) may well lead to consumer apathy. I certainly haven't upgraded 'as much as I could!' recently. Absolutely no justifiable need.
Then again, perhaps we've all had access to enough power we need? We used to talk about 'killer apps/software' to drive consumers into making a purchase. This certainly did work. Maybe new tech (currently available) isn't killer enough? We need another '3dfx Voodoo' experience?
VR is certainly (definite?) a potential driver...here's hoping for speedy and significant updates here.
Hello, yes we did test and attempt to install the HD Graphics 630 drivers. We are working with early BIOS revisions, so it is possible that we encountered a platform-specific issue. Can you share which motherboard you used for your testing? Any feedback is welcome.
Probably to make a statement of some kind.
Kaby Lake best use in Windows 10
Kaby Lake Perfromance it better than what AMD FX Provides so goodluck to far range upgraders.
That's what I read into the 14nm+ label they're using. Atleast with a "14nm+" process you'd think they should've ironed out alot of the production process variability.
I can only conclude that the production process variations of the 14nm+ is greater that the improvement of "going from 14nm to 14nm+".
Is the 14nm+ just a marketing gimmick?
it's not "tick -> tock -> tock" it's "tick -> tock -> tweak"
I'll go with "tick-tock-toe" because this is nowhere near as interesting as a real tock.
I did not use Z270 chipset but Z170. Kaby Lake with Z170 works fine under Windows 7. Again, don't have Z270 motherboard.
I used this board
http://www.asrock.com/mb/Intel/Z170%20Extreme4+/index.us.asp
The latest UEFI update supports Kaby Lake. Works fine under Windows 7 so MS. story of Windows 7 not able to fully support Kaby Lake is a B.S. For Z270 i would wait Intel to release an appropriate drivers and it will happen.
Basically meaningless to anyone that overclocks on Skylake already.
I'm still going to upgrade my 2500k this year but to what exactly I'm not sure.
Hopefully AMD give us a better showing, though I doubt they can match the 7700k in games, and I'm a gamer so it's probably where I'm looking.
I agree. For someone who is about to buy a brand new system, this is a good option but for people who are coming from older generation no need to upgrade. Intel needs to step up but it won't happen until AMD does something. I do hope that new Ryzen costs same as 7700k but being 8/16 and beating high end x99 CPU in business scenarios and 7700K in gaming. It will force Intel to maybe merge x99 and z270 platform into one and lower the price.
