Yuka, you make a good point! They could definitely raise the base clocks higher by doing that, and extend the life of 14nm a little more.
https://www.techspot.com/review/1627-core-i5-8400-vs-ryzen-5-2600/page8.htmlPutting It All Together
Ok, that was a massive session. So now let's put it all together with a look at the average performance across the 36 games tested, let’s do that first.
Starting with the 720p results where we had the least chance of being GPU limited, we see that the Core i5-8400 was on average 13% faster than the stock Ryzen 5 2600. That’s not a huge margin but noteworthy enough. The frame time performance was closer but even here the 8400 was still 10% faster. Overclocking did hand Ryzen the advantage and now the 2600 was 7% faster for the 1% low result and 5% faster for the average frame rate.
Moving to 1080p we see all margins reduced and here overclocking only provided a 13% performance increase and this meant the 2600 was 7% faster than the 8400 for the 1% low result and just 3% for the average frame rate. As expected the margins continued to shrink as the resolution increased and at 1440p there is very little difference between the three configurations.
But when it comes to games the Core i5-8400 simply gets it done with less fuss. To replicate the performance seen in this article you merely need a basic B360 board, some low latency DDR4-2666 memory, and well... a GTX 1080 Ti, but you get the point. It’s also possible to squeeze another 5-10% out of the 8400 by using a Z370 motherboard and DDR4-3200 memory, though those gains are only realized with a high-end graphics card.
The stock out of the box Ryzen 5 2600 performance can be achieved for roughly the same price as the budget Core i5-8400 build, and given the Intel CPU was faster overall this makes it the better value choice for gamers.
The overclocked configuration will require an upgraded cooler, but for the results shown here you’ll also need a quality motherboard and premium Samsung B-die memory. I priced all this up and you’ll be paying ~$420 for the Core i5-8400 platform, while the overclocked Ryzen build is more like $500 with a basic air-cooler.
So if you’re strictly gaming the 20% price premium of the overclocked Ryzen build can’t be easily justified for a 7% average gain. Alternatively, you could spend $500 on the Coffee Lake build and get the 8600K with a basic air cooler, enable MCE, and you’ve got an unstoppable gaming rig.
But, if you do other things besides gaming then the Ryzen shines and the premium is easily justified. Personally I'd go for the Ryzen 5 2600 as I play games but also create video content and the time savings every day encoding will certainly add up. And that's it for this one, you should now be armed with all the facts you need to make an informed purchase, so good luck.
https://www.pcgamesn.com/amd-zen-5-designIn the same team video, which had Suzanne Plummer explaining how they were using Zen CPU expertise to help improve the frequency, performance, and power of next-gen graphics cards, AMD’s Mike Clark admits that he’s already working ahead on Zen 5.
“It’s very exciting,” he says. “As an architect I’m already working on Zen 5 actually.”
We know that the AMD Zen 2 is design-complete and is going to begin sampling before the end of 2018, ready for a likely launch in March/April of 2019, and that they have been working on the AMD Zen 3 design for a while. With the promise that their leapfrogging design teams will always work on developing the next two generations, and the second-gen CPUs being essentially finished, it makes sense for AMD to be working on the fourth-gen Zen chips.
“The New AMD will be working on shipping a current CPU," AMD's Mark Papermaster told us back in May last year, "and developing the next two generations, at any point in time. That’s our commitment to our customers.”
But how come Mike Clark is hard at work on Zen 5, where is Zen 4? The general consensus seems to be that because the number 4 is seen as very unlucky in China it’s quite possible AMD aren’t just leapfrogging with Zen 4, they’re double-jumping right over the top of it.
One of Sony's compiler experts has taken to working on some tuning for the AMD Ryzen "znver1" microarchitecture support within the LLVM compiler stack. This begs the question why Sony is working on Ryzen improvements if not for a future product.
Sony's Simon Pilgrim has been recently investing time in the "znver1" AMD first-generation Zen CPU support within LLVM. Simon has been a programmer for Sony for the past decade. His LinkedIn reveals that indeed at Sony he's working on compiler tooling for the PlayStation devices:
https://www.phoronix.com/scan.php?page=news_item&px=Sony-LLVM-Ryzen-ImprovementsOn Friday he submitted a cleanup for the znver1 code, last week were more Znver1 changes across multiple commits, and these upstream Znver1 LLVM improvements by this Sony programmer have been going back at least two weeks with this just not being some one-off cleanup attempt. Thanks to Phoronix reader Stephane for helping to spot this trend.
It's interesting that Sony is working on upstream LLVM improvements specific to AMD Zen processors when they aren't currently shipping any Ryzen/EPYC-based systems. But let's not forget that the PlayStation 4 is powered by a semi-custom AMD Jaguar CPU with GCN Radeon graphics. On top of that, Sony indeed uses LLVM/Clang as the compiler for the PlayStation 4. In fact, they contributed the PS4 support to upstream LLVM and have dealt with the upstream LLVM compiler community over the years.
So for now we're thankful that more hands are working on AMD Zen compiler improvements, but if I had to bet, it wouldn't be too surprising if the PlayStation 5 is powered by a Ryzen CPU/APU given the PS4 being a semi-custom AMD part and that the PlayStation 5 is speculated for debut in the next year or two.

Process node N7 is in volume production, with >50 customer tapeouts expected by YE'18.
Although the initial target was the Mobile platform, there is an N7 variant developed specifically for HPC. A new 7.5 track SC library was developed (versus 6T for Mobile_. The N7 HPC option also includes a larger contacted poly pitch and wider metals, and a new "super high-density" MIM capacitor.
