AMD Ryzen 1700 Emulation Testing...

[Josh128]

Pretty fantastic. How do you find NullDC and PCSX these days as far as actual play quality?

Crazy Taxi on NullDC was essentially perfect, other than that streak on the title screen, no hitches in gameplay or really anything to give away that its not the real system! PCSX2 looks and plays fantastic in game in Gradius V, the sound is great as well. FMV for what ever reason runs slow though. Noticable, but not a deal breaker. CCC looks and plays perfect, GOW and MGS3 also seemed pretty spot on.

Used a wireless Xbox360 controller with the Microsoft USB receiver and it works great-- in fact, I didn't even have to configure the buttons in NullDC-- just booted up and I guess it mapped the controller by default! Overall I'd say MUCH better speed and playability ( and I'm sure, compatibility) than was possible back around 2008-2010 in my Wolfdale E8400 days.

Very cool...

That 360 pad is pretty much the spiritual evolution of the DC controller too

[tomwhite2004]

BTW DeMUL sucks, NullDC is the way to go for DC emulation.

Demul has its place, its far more accurate than NullDC and is still in active development, but its CPU and GPU requirements are way higher than most builds are capable of running (eg http://www.emutalk.net/threads/55734-Vi ... -64-Layers).
NullDC has a few problem games displaying issues with graphics and textures, notably Shenmue 1+2 with the shadows and hair. Its a shame that it has been seemingly abandoned at ver 1.0.4 as it is much lighter on the CPU as has far less input lag.

FMV for what ever reason runs slow though.

Hardware mode can cause loads of problems with FMV playback in PCSX2.
Go to Config>Video>Core GS Settings>Game Fixes and tick "Switch to GSdx software rendering when an FMV plays". It should now play at full speed.

The original Xbox controller was the real spiritual successor, in fact at one time Sega wanted the Xbox to be backwards compatible with Dreamcast discs but it all fell apart over internet connectivity problems.

Cool, will try that.

Oh well, so much for Ryzen in Scorpio... using 16nm Jaguar variant at 2.3GHz. 4K 60 Forza looks good though...

[mikejmoffitt]

I also have a Ryzen build, and I am running Windows 7. If there's anything you'd like to see tried on it, let me know.

I could not get Win7 working kosher on my Gigabyte gaming board despite following their directions for installing on Win7. The USB 3.1 drivers were found, but could not be loaded. Also, anytime I tried to install a program it would have an error. Win 10 has been a pleasant surprise though. Not too bad.

Can you run the standard Dolphin benchmark? Also, if you have them, can you try running the in game FZero (Fire Stingray, 640x480,1st Course, Practice, no opponents, sitting at start line) DX11 and DX12 (does Win 7 even support DX12?), Mace:The Dark Age on MAME64, and Crazy Taxi on NullDC? I'm not sure what proc or speed you are running, but I have run both 3.0GHz stock and some 3.6 and 3.9 (listed on the screenshots if not stock freq). Ive played around with SMT ON/OFF and various CCX configurations but to be honest it didn't look like it made any difference.

What kind of mobo and RAM/speed are you using?

Of course, if you want to offer up anything I haven't touched on yet either, feel free.

I think the customizations they've done are much more interesting than throwing Ryzen in there. It's the most custom console I think we've seen since the 6th console gen.

16nm process tech. Just a slight bit over the current state of the art 14. The "2 clusters of 4 cores" sound an awful lot like Ryzen though. It sounds like at least some parts of the Ryzen design may have been borrowed from to make these cores. They said the cores are 31% faster than Xbox 1, but I'm not clear on if that means clock speed, or instructions per clock. Could be the former, could be the latter, could be a combination of both...

[Josh128]

Checked out Rogue Leader, one of my all time fav 6th gen games. Seems a lot more CPU intensive than FZero, but runs at over 60 nonetheless. Heres an in game snapshot of a graphically intensive moment still pulling 90. Even at lower resolutions, its running about the same speed which tells me it wasn't my GPU bottlenecking here. BTW this is running with SMT enabled, as have all the tests Ive done so far.

*EDIT - spent some time playing locked at 60 fps, at least in the first level, the emulation is amazing, nigh on perfect I'd even say. Hard to tell I wasn't playing the real game (that is, until I switched on my targeting computer and the emulator froze. ). Really phenomenal looking game in 1152x864 on my 19" ViewSonic CRT monitor.

[Josh128]

Some more playing around with Dolphin. Found a game that can drop below 60 at times at stock 3GHz speed, Rebel Strike. Still completely playable and utterly enjoyable, it does have drops into the 40's at times. Havent tried to OC yet. Had fun playing several levels (even the crappy on foot levels ), I had almost forgotten how utterly beautiful this game was, Factor 5 were really wizards of the GC hardware. IMO the most beautiful and graphically impressive game of the entire DC/PS2/GC/Xbox era...

[Josh128]

Not exactly on topic but I had to convert 2 CD's worth of music to MP3 for my wifes MP3 player last night. Used RazorLAME and noticed it was running pretty fast, faster than I recall last time I used LAME. Encoded 34 MP3s from WAV in 1:55. Not sure how multithreaded LAME is, but yeah seemed pretty quick...

What did you have before ryzen? I have a 2600k @4.4Ghz, wondering whether it's worth upgrading to ryzen this year.

My computer chokes if I try to run a Matlab simulation + Xilinx ISE/vivado + video capture from my xcapture1. I would ideally like a CPU that can handle having 2-4 engineering programs at once plus chrome, Microsoft word, PowerPoint, and PDF viewer.

Basically, would you able to see how many "big" non-game programs you can run before it gets unusable?

[Josh128]

I had/still have a Core i5 2500k. I can tell you that with MAME, if the Mace game was running, opening more than 1 other MAME session of a 3D or 100+MHz CPU game would cause it to bog / CPU utilization pegged at 100%. In fact I have screen grabs I can upload later of exactly what the 2500k was capable of. With the Ryzen, at stock 3GHz, I was able to run 7 simultaneous sessions of CPU intensive MAME games, and only got the CPU utilization to 75% (which BTW is the highest Ive seen since building the system). You can see the screen grabs earlier in this thread.

I dont have any engineering programs to really try, but I can say for both engineering progs AND running multiple simultaneous programs, Ryzen is the chip you want. It actually excelled at running engineering apps in the many reviews out there, and has excellent multithreading performance. For running multiple simulataneous apps, RAM should also be taken into consideration as it can run out before the CPU can in some scenarios. As I said, I dont have any engineering programs per se, but if you have a specific example you want to see let me know and I can post it along with CPU/RAM utilization.

[Woozle]

Thanks for the info. Knowing it can handle all the MAME sessions is a good indication of it's multi-tasking abilities.

Would you be able to slice a 3D model in replicatorG? I would be curious to see how the 2500k performs vs the 1700 on a relatively complex model. Don't worry if you can't, this thread is still helpful.

If it was only doing one track at a time, it's not going to be any faster .. you need an encoder front-end that can run multiple instances at once.

[mvsfan]

I have my eye on this. http://www.ebay.com/itm/292066731590?_t ... EBIDX%3AIT

[Josh128]

Nice looking board, the MSI Tomahawks are supposed to be very good boards.

I'm using a Gigabyte GAMING 1.

A pretty no-frills board, but has been solid so far, despite some pretty severe abuse (lets just say I f'ed up royally during the new system build ), plus it has cool led lights on it. It recognized my 2667MHz RAM at proper speed on first boot, and I have since updated to the newest 1.0.0.4 AGESA bios without issue. I did have driver issues (aside from the USB mouse one) with Win 7, so I just went with Win10 and its been great so far.

[mvsfan]

Yeah. the nice thing about that motherboard is that it still has rs232 and parallel support since i still have a few things that use those.


as far as the pci slots go, i could really do without those although they are good for usb cards.

I'd like to preface this with a big, "I don't know diddly squat about 3D printing or ReplicatorG", but I was able to find and "slice" (at least I learned what that means, lol) a relatively simple (sorry) model from a .STL file. The file is the "beer mug" file found here. I used ReplicatorG 0040 and Python 2.7.13. I didn't change any options from the default, I simply hit "Generate G Code" and let it rip. Ryzen 1700 was at default clocks with 2667MHz RAM.

Long story short, it took 4:01. This program does not appear to be multithreaded at all, as the CPU utilization hovered between 8% and 12%. I find that a bit odd that such a program does not take advantage of multiple cores/threads, but regardless, you asked and I tried. In light of it being single threaded, I suspect the result is probably nothing special.

First pic shows CPU utilization about mid-slice.



This pic shows slice time.

I had an i7-3770 before. Not really problematically old, but I was very interested in supporting a proper intel competitor when Ryzen came out.

I can screw around with trying a capture (USB3HDCAP, ~= xcapture 1), compiling stuff in Quartus II, screwing with some PCB design, and compiling a large C project as well as usual bullshit like a web browser, etc. I haven't put any intentional stressful loads on it for the sake of testing, but I compiled the Gendev Sega Genesis toolchain as well as the Allegro library pretty fast.

[Josh128]

Ran a few more MAME emulation tests on games I remember being difficult. Virtua Racing, Mortal Kombat 4, and NFL Blitz. All are playable at stock speeds, MK4 and Blitz will dip below 100% but running at 3.6GHz fixes that. VR is blazing fast.

[Josh128]

Some Supermodel runs. Stock 3.0GHz speed seems adequate, never saw it dip below 60 in any game, usually in 70s or higher. Clocking to 3.6GHz boosts frames 20% or so.

[mvsfan]

Right now i have a Phenom II 960t thats unlocked to an X6 at 3.2ghz with 8gb ram. its plenty fast for what i do. but of course im interested in Ryzen.

according to some specs i was looking at its about twice as fast as my Phenom for multitasking.

[Josh128]

Yeah AMD has a winner here with the Ryzen chips. They may not beat Intels top chips clock for clock IPC but they come close enough-- and you get much more bang for your $. I saw some sales the other day on the net with 1700 @ $310 and 1700x @ $359.

If you are still on a quad core older than Haswell there is really no good reason not to opt for a 1600 or 1700 at these prices-- they both come with kick ass coolers and can easily OC to at least to 3.8 on stock cooler. I mean, the 1600 is like $219-- unless people are waiting for them to GIVE these chips away you aint getting a much better deal than that. Plus by doing so you are supporting competition in a field that was effectively monopolized by Chipzilla for at least the last 8 years or so. I feel good about that. If AMD goes down its all over, Intel will stagnate tech and continue with their current expensive as hell price structure as they have been doing for the last 5+ years. The average Joe Shmoe I know is probably ignorant to that fact, but supporting AMD now will only help us get better tech at more reasonable prices down the road.

I came from an i5 2500 on this rig and the general desktop responsiveness is very noticeable. I was due for an upgrade anyway due to some mobo issues so I jumped on the 8 core when I read the reviews. I paid $329 for the chip/RGB cooler combo and feel it was a great deal.

[Josh128]

I said earlier Ryzen IPC doesn't quite match Intels top chips. That actually kind of depends on what your doing. Sure, this is cherry picking, and yes one can find benches that show the opposite, but for whatever reason, Ryzen kicks extreme ass in the CPU-Z benchmark, besting even Intels top chips clock for clock. This page is from my favorite hardware site, guru3d.com (shout out to Hilbert H!)



http://www.guru3d.com/articles_pages/am ... iew,9.html

So, despite Intels clear lead in games (MOST games, not all though), there is obviously a bit of special sauce in these Ryzen
CPUs and they are indeed cutting edge tech that in my opinion, no one should feel bad for taking a chance on them. Its probably tempting at this point to wait and see how Intel responds, or to see if Zen 2 ups the ante even more, but the tech and value is so good that they really deserve our business now. Maybe it can be the shot in the arm they need to continue the David vs. Goliath battle.

[Udderdude]

Zen is a new architecture. There is plenty of room for improvement. Zen 2 will definitely have some real performance gains. Unlike a certian other blue-flavored company .. who claims 15% performance gains and delivers 5% if you're lucky.

The nice thing about the AM4 platform is that AMD won't be pulling the rug out from under you and forcing you to buy a new Motherboard and RAM just to upgrade your CPU. Unlike a certian other blue-flavored company .. who switches sockets every time the wind changes.

[Josh128]

Ebay has the 1600X at $219 and the 1700X at $319. Killer deals.

Do you have some specific info on this or is it just your faith in AMD?

Also, I'm glad they will be keeping AM4 around for a bit too, but I don't expect it to last forever.

[Udderdude]

AMD has claimed 10-15% IPC increases for Zen 2 and 3. I'm just going on AMD's word here, but considering Zen is a new architecture and should have plenty of low hanging fruit for improvement, I don't see any reason to doubt them. http://www.game-debate.com/news/22457/a ... 018-launch

AM4 should last at least until DDR5 RAM goes mainstream. AMD has claimed they want AM4 to stay around for "A long time". http://wccftech.com/amd-pinnacle-ridge-cpu-zen-2-core/

I'll certianly trust them over Intel, who has consistently lied about performance gains, and has been fined billions for bribing OEMs and putting "Cripple AMD" functions into their own compiler.
