The AMD 2nd Gen Ryzen Deep Dive: The 2700X, 2700, 2600X, and 2600 Tested
by Ian Cutress on April 19, 2018 9:00 AM ESTCPU System Tests
Our first set of tests is our general system tests. These set of tests are meant to emulate more about what people usually do on a system, like opening large files or processing small stacks of data. This is a bit different to our office testing, which uses more industry standard benchmarks, and a few of the benchmarks here are relatively new and different.
All of our benchmark results can also be found in our benchmark engine, Bench.
FCAT Processing: link
One of the more interesting workloads that has crossed our desks in recent quarters is FCAT - the tool we use to measure stuttering in gaming due to dropped or runt frames. The FCAT process requires enabling a color-based overlay onto a game, recording the gameplay, and then parsing the video file through the analysis software. The software is mostly single-threaded, however because the video is basically in a raw format, the file size is large and requires moving a lot of data around. For our test, we take a 90-second clip of the Rise of the Tomb Raider benchmark running on a GTX 980 Ti at 1440p, which comes in around 21 GB, and measure the time it takes to process through the visual analysis tool.
FCAT is a purely single threaded task, and it takes benefits from the top frequency parts and high IPC from Intel. On the AMD front, the Ryzen 5 parts are scoring better than the Ryzen 7 parts, but are within an error margin.
Dolphin Benchmark: link
Many emulators are often bound by single thread CPU performance, and general reports tended to suggest that Haswell provided a significant boost to emulator performance. This benchmark runs a Wii program that ray traces a complex 3D scene inside the Dolphin Wii emulator. Performance on this benchmark is a good proxy of the speed of Dolphin CPU emulation, which is an intensive single core task using most aspects of a CPU. Results are given in minutes, where the Wii itself scores 17.53 minutes (1052 seconds).
Dolphin is also a single threaded test, and has historically had benefits on Intel CPUs. The new Ryzen-2000 series, with extra IPC and frequency, are pushing ahead of Intel's Skylake parts.
3D Movement Algorithm Test v2.1: link
This is the latest version of the self-penned 3DPM benchmark. The goal of 3DPM is to simulate semi-optimized scientific algorithms taken directly from my doctorate thesis. Version 2.1 improves over 2.0 by passing the main particle structs by reference rather than by value, and decreasing the amount of double->float->double recasts the compiler was adding in. It affords a ~25% speed-up over v2.0, which means new data.
For this multi-threaded test, the new 8-core Ryzen 7 2700X pulls further head of Intel's 8-core Skylake-X compared to the 1800X. At six cores however, the Coffee Lake i7-8700K is sandwiched between the Ryzen 5 2600X and Ryzen 5 2600.
Agisoft Photoscan 1.3: link
Photoscan stays in our benchmark suite from the previous version, however now we are running on Windows 10 so features such as Speed Shift on the latest processors come into play. The concept of Photoscan is translating many 2D images into a 3D model - so the more detailed the images, and the more you have, the better the model. The algorithm has four stages, some single threaded and some multi-threaded, along with some cache/memory dependency in there as well. For some of the more variable threaded workload, features such as Speed Shift and XFR will be able to take advantage of CPU stalls or downtime, giving sizeable speedups on newer microarchitectures.
Photoscan is a variable threaded test, and time improvement from the 1800X to the 2700X shows the extra TDP and Precision Boost 2 can literally shave minutes from a test. Intel's slower mesh architecture of Skylake-X on the 8-core 7820X compared to the ring architecture of the Coffee Lake 8700K means that the two fewer cores on the 8700K allows them to draw level, but they are still four minutes or so behind the Ryzen 7 2700X. The big 18-core Intel CPU, the i9-7980XE, is needed to win here.
Civilization6 AI Test
Our Civilization AI test uses the steam version of Civilization 6 and runs the in-game AI test to process 25 rounds of an example end-game. We run the benchmark on our GTX 1080 at 1080p Medium to ensure that rendering is not a limiting factor, and the results are given as the geometric mean of the 25 rounds in the test, to give the average time to process one round of AI.
Parts of the AI test can use multiple threads, however the extra single core performance on Intel does push those parts into the lead.

Oh, I'm actually curious about your experience with all the systems.I'm still running my i7 2700K at ~4.6Ghz. I do agree I haven't felt that it's a ~2012 CPU and it does everything pretty damn well still, but I'd like to know if you have noticed a difference between the new AMD and your Sandy Bridge. Same for when you assemble the 2700X.
I'm trying to find an excuse to get the 2700X, but I just can't find one, haha.
Cheers!

The the once in a lifetime chance to largely keep your CPU name (2700K => 2700X) should be all the excuse you need.YukaKun - Monday, April 23, 2018 - link
That is so incredibly superficial and dumb... I love it!Cheers!

YukaKun, your 2700K is only at 4.6? Deary me, should be 5.0 and proud, doable with just a basic TRUE and one fan. 8) For reference btw, a 2700K at 5GHz gives the same threaded performance as a 6700K at stock.And I made a typo in my earlier reply, mentioned the wrong XEON model, should have been the 2680 V2.

For daily usage and stability, I found that 4.6Ghz worked best in terms of noise/heat/power ratios.I also did not disable any power saving features, so it does not work unnecessarily when not under heavy load.
I'm using AS5 with a TT Frio (the original one) on top, so it's whisper quiet at 4.6Ghz and I like it like that. When I made it work at 5Ghz, I found I had to have the fans near 100%, so it wasn't something I'd like, TBH.
But, all of this to say: yes, I've done it, but settled with 4.6Ghz.
Cheers!

(an old thread, but in case someone comes across it...)I use dynamic vcore so I still get the clock/voltage drops when idle. I'm using a Corsair H80 with 2x NDS 120mm PWM, so also quiet even at full load; no need for such OTT cooling to handle the load heat, but using an H80 means one can have low noise aswell. An ironic advantage of the lower thermal density of the older process sizes. Modern CPUs with the same TDP dump it out in a smaller area, making it more difficult to keep cool.
Having said that, I've been recently pondering an upgrade to have much better general idle power draw and a decent bump for threaded performance. Considering a Ryzem 5 2600 or 7 2700, but might wait for Zen2, not sure yet.

No, it might have to do with the fact that the 8350K has 1.5x the cache size and beastly per-thread performance that is also sustained at all times—so it doesn't have to switch from a lower-powered state (which the older CPUs were slower at), nor does it taper off as other cores get loaded, which is most noticeable on the the things Samus mentioned, ie. "boot times, app launches and gaming". Boot times and app launches are both essentially single-thread tasks with no prior context, and gaming is where a CPU upgrade like that will improve worst-case scenarios by at least an order of magnitude, which is really what's most noticeable.For instance, if your monitor is 60Hz and your average framerate is 70, you won't notice the difference between 60 and 70—you will only notice the time spent under 60. Even a mildly overclocked 8350K is still the one of best gaming CPUs for this reason, easily rivaling or outperforming previous-gen Ryzens in most cases and often being on par with the much more expensive 8700K where thread count isn't as important as per-thread performance for responsiveness and eliminating stutters. When pushed to or above 5 GHz, I'm reasonably certain it will still give many of the newer, more expensive chips, a run for their money.

Memory prices? Memory prices are still pretty much the way they've always been:-- faster memory costs (a little) more than slower memory
-- larger memory sticks/kits cost (a little) more than smaller sticks/kits
-- last-gen RAM (DDR3) is (very slightly) cheaper than current-gen RAM (DDR4)
I suppose you can wait 5 billion years for the Sun to fade out, at which point all RAM (or whatever has replaced it by then) will have the same cost ($0...since no one will be around to buy or sell it)...but I don't think you need to worry about that.

You didn't write anything about price there... All you've said is that relative pricing for things is the same it has always been, and that's no surprise.The $$$ cost of any give stick is more than it was a year or two ago. 2x8gb DDR4-3200 G.Skill Ripjaws V is $180 on Newegg today. It was $80 two years ago. Clearly not the way they've always been...
