Hi everyone. I'm posting this to share my results with my new Ryzen CPU compared to an i7 CPU. I haven't seen anything online about testing the Ryzen with Sketchup or Podium, and the Podium team hasn't tested Ryzen yet, so I'd thought I'd throw my results out there if anyone is interested. So, here's my test and results. If you don't care how I did what I did or how I came up with the number I came up with, just skip to the end:

 

System Specs:

(Old computer) i7 4790k overclocked from 4.0GHz to 4.8GHz (making it theoretically the same or more powerful than the i7 7700k at base clock). RAM is 16GB of DDR3 RAM @2133MHz

 

(New computer) Ryzen 7 1700X at 3.4 GHz (not overclocked). RAM is 16GB of DDR4 @2133MHz. (NOTE: I turned down the voltage on my CPU from its default 1.46v to 1.35v due to higher than I'd like temperatures, so it's possible that keeping the voltage higher could increase performance. With that said, at 1.35v, the CPU never heated up past 40C, which is very good)

 

(NOTE: Both systems used a Gigabyte Windforce Nvidia GTX 1070 8GB GDDR5 overclocked by 100MHz for memory and core)

 

Testing:

I started by building a complex model in Sketchup with a ton of reflective surfaces and a lot of lights and surfaces. My model's info is attached to this post. I know some of the info might seem a bit excessive. That was the point; make something very complicated to shoot the render times through the roof. That’s why I have a 3 huge waterfalls in my model.

 

 

Results:

(Render 1) I started with a long render with a high resolution (4500x2690, basically a 10x17 print with 300dpi), preset to "interior_fine_AA" with shadows on. It’s a weird resolution, but that’s what I could get without messing with my model too much.

(Render 2) Then I did 1000x597 render with the same preset and shadows.

(Render 3)Then an "Interior_preview" render at 1000x597.

 

Below are the times I got:

 

(Render 1):

i7 time: 12:07:56.2

Ryzen time: 08:34:08.3

Difference: Approx. 70.7% faster on Ryzen

 

(Render 2)

i7 time: 58:33.7

Ryzen time: 40:32.3

Difference: Approx. 68% faster on Ryzen

 

(Render 3)

i7 time: 8:35.8 - 7:47.6 (Note: I messed up my notes, so the two times are a rough estimate)

Ryzen time: 05:34.2

Difference: Rough approx. 50%-70% faster on Ryzen

 

Extra Results:

Ryzen temperature never went above 40C. The i7 was hovering around 68-72C for all tests. (Keep in mind the i7 is overclocked and the Ryzen is undervolted from its default voltage).

Power draw from the wall was about 10% less on the Ryzen build vs the i7 build.

 

*Conclusion:

A Ryzen CPU costs between $325-$475 (at the time of writing). My 1700X cost $386.

A i7 7700K costs $350.

You can get 70% better performance with a CPU costing about the same at the i7. Not only that, but other tests by other people have shown that even Intel’s 16 thread i7 and Xions preform about the same as Ryzen, but with a +200% increase of cost for the intel chips over the Ryzen chips.

Long story short, Ryzen gets you a 60-70% increase for the same amount of money as an i7 in Podium Renders. All of my other multi core tests (RealBench, 3DMark Firestrike, 3DMark Time Spy, and Cinebench CPU test) all show between a 50%-75% increase in performance between my i7 4790k and the new Ryzen 1700X, even when my i7 4790k is overclocked and pulling better numbers than the newer i7 7700k (numbers taken approx. from the difference between the 4790k and 7700k, according to Intel, as well as benchmark results from other benchmarks).

Longer story shorter, if you're thinking about upgrading to a new intel 4 core (8 thread) i7, just get a Ryzen 7.

EDIT:
In the attached file, it says the operating system is Windows 8.1. It is not. I'm using Windows 10. It probably says that because I used the free upgrade to Windows 10 from 8.1

Great information - and very useful! Most of us thought the the Ryzen CPU would be great for rendering, and now you've proved it [smile]

Thanks a lot for sharing this, it's much appreciated.

If AMD and it's partners can deliver on Ryzen and keep updating their BIOS as promised then my work PC will quickly be an AMD machine on the next upgrade cycle.

***Update: I have come across a few glitches in my last few Ryzen renders. Wether or not this has to do with the lack of optamazation with Ryzen or just a quark in the new hardware, I don't know. Just thought I'd throw these out there so you all know. Maybe someone can tell me if I'm just being stupid and missing something obvious [smile]. :

From time to time the render just doesn't work. It renders a full white screen. No geomatry, no color, or I can see through some walls for no reason. I try it again and it renders fine. Not a big issue but can be annoying.

I get a really weird error message saying "!!! Icon Unknown." Most of the time the error message goes away and the render continues, but a few times Sketchup and Podium crashed.

Podium just straight up didn't work once or twice. I try to render, the sketchup render server thing pops up, loads, and then Windows says that the Podium timed request (or something to that effect) has been canceled.

Most of these glitches (except the last one) can be fixed with a computer restart, so most aren't a huge deal.

Hum, we've seen !!!Unknown Symbol" message but never unknown icon...If its really the exact message its ought to be something new indeed.


I goes without saying, but you have the latest podium build right? [smile]

Ah. Yes. Sorry. "!!!Unknown Symbol" is the error message I got. Sorry.

I do have the newest version of Podium.

Run Podium Tools, sounds like a texture error to me.

I thought I would continue to post updates here to both inform others about Ryzen and to give info to Podium to possibly improve performance with Ryzen and possibly other CPUs.

I've come across a new issue, I think. I haven't tested this with other CPUs, but I haven't noticed this before on my old i7 build. This doesn't mean it's an issue just with Ryzen, and I'm not sure it's a real issue at all, but I thought I would still post about it to see if there is a fix for it or if it's just part of Podium.

While rendering, during the pre-render phase, there is a time where all of my CPU cores stop running at full power. It only happens during this phase. The render starts of slow, then at some points just up in speed incredibly fast and then slows down. After looking into this, I found out that my CPU cores slow down to 5-10% for a few seconds/minutes and then jump back up later to 100%. It has nothing to do with thermal throttling (my CPU has never hit above 45c) or RAM (I have 16GB of RAM and I've never used more than 13GB at any one time while rendering). 

I can only think of two reasons for this: 1, Ryzen and Podium have issues with each other at certain times or Ryzen doesn't like the pre-render process of podium. Or 2, Podium rendering forces the CPU to slow down at certain parts. 

If anyone can confirm that their CPU slows down during pre-render or that this is just part of Podium, that would be great! While the speeds are still much faster on Ryzen when compaired to Intel, I have no idea why Podium would force my CPU to slow down at times during the first phase. I feel like it would be much faster to render if you have a CPU run full power non-stop.

Attached is an image of my resource monitor showing what the slow cores look like. (NOTE: I know the first phase ended and was starting the second phase. The chart was virtually the same during the slow parts of the render, which is why I used this as representation. It would slow down and then speed up, as shown in the chart.)

Thanks for keeping us posted!

The render process has a few phases, so it would be normal to have a short slow down when switching. But what you have here can seam long indeed!

I'd have to check how my i7's reacts.

Update #2

Podium is still running great on my Ryzen CPU. I have fixed(?) the issue I mentioned in my last update. I had to force the core to run faster. However, after doing this, and comparing render times on a new project I'm working on, there seems to be no real difference in time, at least nothing that can't be considered margin of error. I guess Podium just forces the CPU to calm down for a little bit while it loads the next part of the pre-render phase...

I've also tested my Ryzen with the voltage turned up to it's stock voltage (which, by the way, are WAY OUTSIDE AMD's own recommended voltages, so if you get Ryzen, change the voltage RIGHT AWAY to what I have listed above) and it turns out that, yes, increasing the voltage close to what it was at when I got it decreased render times by 2%-4%, using the same tests I did in the beginning. So, in my opinion, it's not worth it to keep the voltage high and risk heat or voltage damage to the CPU.

Great, thanks for the update.

Have you run other softwares or games with it? Curious to see how it compares with intel on a day to day basis.

Yes, Nick00, I have. I've run a few games on it (not many, since I don't have a ton of time for them anymore), and a few other popular programs on it.

In games, at least the games I play, there's not a huge difference in power, since the GPU I have (GTX 1070) is plenty powerful and the CPU doesn't bottleneck it. At worst, Ryzen gets 5-10 fps slower than an intel CPU, which isn't bad when the GTX 1070 pulls easy 100fps on almost every game at 1080p.

In Photoshop and Lightroom, my other most used programs, I don't see a difference. Admittedly, I haven't actually tested and compared my i7 to Ryzen, but, if anything, Ryzen gets very slightly slower performance. But, like I said, for what I do, I see literally no difference. In Lightroom it runs slightly better than that i7. At least, it seems that way, especally when I use my presets (they load faster).

No other differences between the two in most other day-to-day apps, or at least nothing that's noticeable.

From my experience, day-to-day, ether CPU is good. But, if you need a high core count, like for 3D or movie rendering, exporting complex file, or really most things that cost money as more and more programs move to multicore processes, a Ryzen is clearly the better pick, in my opinion. Honestly, Ryzen 7 seems to be made for 3D artists and content creators, Ryzen 5 is for gamers and light workstation use, and Ryzen 3 is made for the average person and budget gamers. At least, that's my opinion.

So long as the Ryzen is compatible to GTX GPUs.  I think it is.
