This topic is created to find the best performance/price CPUs for using with DSP56300 Emulator and other CPU hungry vst plugins.


CPU TEST
We will be testing our CPU's on two ways and put results here.

1. First Download DSP56300 Emulator and Test Console
Official Website -> https://dsp56300.wordpress.com/downloads

Direct Downloads:
Test Console -> https://futurenoize.com/dsp56300/builds/master/DSP56300Emu-1.2.20-win64-testConsole.zip

DSP56300 Emulator
VST2 -> https://futurenoize.com/dsp56300/builds/master/DSP56300Emu-1.2.20-win64-VST2.zip
VST3 -> https://futurenoize.com/dsp56300/builds/master/DSP56300Emu-1.2.20-win64-VST3.zip

2. Download ROM
We will be making Tests using only one ROM.
The best version available
Virus C (6v5)

ROM name: virus_c_650x352.bin
You can find this ROM easly on the net.

Copy this ROM into folder containing your DSP56300 plugin and into folder with Test Console

3. Download Preset
I modify existing preset to make it ugly and turn on everything possible in the synth (polyphony, unison max 16 voices, distortion, delay etc.) to make it very cpu hungry.

Preset -> You can find preset in the attachment called "CPU TEST.zip"

4. TEST 1
Run Test Console (file named "virusTestConsole.exe")
Wait 1 minute and take the screenshot of the end of console window (MIPS average results only)

5. TEST 2
Run DSP56300 Emulator VST in your DAW
Load Preset: "CPU TEST"
Press 1 note, click and hold few times on your midi keyboard and watch at the average percentage of CPU consumption in your DAW
Write in the notepad or take a screenshot of the fluctuations (ex. 12% - 15% CPU)

6. TEST 3
This test will show how many instances of DSP Emulator your DAW can handle
Run DSP56300 Emulator VST in your DAW
Load Preset: "CPU TEST"
Make 1 Midi note 1 bar long, loop it and click play
Duplicate Audio Track with plugin few times until your CPU hit 99% or start to be laggy
Make sure that all the instances playing 1 midi note bar loop

Don't know, but 1.2.18 has no glitches on my i7-3770k, but there were a couple of rare glitches on same complex presets playing chords.
When I updated to 1.2.20, it seems like it is already perfect for my old 2012 machine.
Virus C 6.5, Virus B, i7-3770k 16 GB RAM, win7 x64, reaper 6.68 latest beta x64

I don't do any tests anymore, I just test it in my projects, usually i don't need more than 2-3 instances of dsp56300 or just render tracks and then insert another instance to unload a bit, because my projects are overloaded by vsti and vsts. It is still hard to use them in projects and it heats cpu, but realtime use is now many times better and smoother than year ago.

This replaced my broken virus c hardware 100% than any virus-like plugins (viper is good than any, but dsp56300 is identical to hardware, bit perfect).
This (dsp56300) sounds way dirtier in 44100, than in 48000 or higher. Did many tests and analysis with low sines (so it needs better SRC converting from native virus dsp code (46875Hz) to DAW project sample rate (44100,48000,88200,96000,192000,176400....)).

It's interesting that 1GHz make that HUGE difference!

Your CPU is Intel i7 3.5GHz (4 Cores, 8 Logical Processors).
And You can run 3 instances of DSP Emu without any problem!

My CPU is Intel i7 2.4GHz (4 Cores, 8 Logical Processors).
And DSP Emu eats my CPU for breakfast.

I have set minimum sample rate (48kHz) and maximum latency (100ms) on my ASIO driver and I can't run even 1 instance.
It's very unstable. When I use it even without unison voices after 15 minutes it spikes my CPU to 150% - 300% and makes a Laggy Zombie from my PC.

 

Yes 2.4 is to slow. My 3.6 manages. But it is an emu so if to slow it gets very weird unlike normal vsti.
Speed of the cpu is everything with this emu, age of the CPU much less. My old Core2quad at 4ghz runs it just as good as my 9th gen i7 also at 4ghz

I wonder if audio drivers have impact on this. I´ve noticed some improvements over performance, if change from ASIO4ALL to Steinberg ASIO driver, but I haven´t tried it with the emu yet. Gonna try later this evening after work.

BTW My laptop is running 339 MIPS on B Rom, but with this C rom 480 MIPS
My laptop is cheap Cepter with AMD Ryzen 5 4500U with 16 Gb DDR4

 

What the Fuck ??? with an i7 85-99% CPU usage is really Bad.

 

The Problem here is not the CPU it's the Code of the Programm.

 

You have to check the i7 (CPU) generation too, that's an old i7 with a limited CPU frequency.

There're eleven and that without counting the 12th and upcoming 13th which are a new design. I have a cheap-ass 9th gen i3-9100F but still has 4.2-4Ghz frequency.

Also, the number of cores for benchmarking doesn't matter. It's a single-core plugin like almost all plugins. Of course that number counts on a real DAW session with many plugins running.

 

On the site they said:
"As the Virus C runs at 136MHz a result of 136 MIPS or more is needed to run it comfortably"

I have 168 MIPS and it not run comfortably and is very unstable. There are 300% CPU spikes!
Is there something wrong with my computer or setup or 2.4 GHz CPU even if MIPS are above 136 is too weak?

 

I hope this helps..

I7 10700k
48 / 24 bit

 

That seems to be okay for an newer i7 2,3 % CPU but even for an 3rd or 4rd Gen i7 85-90% Percent seems Way to much @Daisy69 check your CPU Usage beside from the Emu there should be something going wrong. I'm on an I5 7200u and the most CPU spikes i get is when using Omnisphere some presets like 50-70%.

Also i read here often that Members with better Systems are getting in Trouble because of HDD or SSD Space even if i have 2GB Space left on my Windows SSD Drive everything runs smooth. Most of the time Driver Problems or Stuff like that is making trouble.

I'm working @ 2-3rd Level IT Support and most of the time Layer 8 (The User) is the Problem (Even at my work most Members of the Team don't know how to install an new OS the right way, because they don't teach you this at school.)

I tried few different presets and I have max
Omnisphere - 12% - 18%
Serum - 16% - 22%
Sylenth1 - 10% - 14%
Spire - 12% - 16%

 

Did you use Omnisphere Factory Presets or Custom made ones?

 

CPU: AMD Ryzen 3900x
OS: Windows 10 (version 1909)
VST Version: DSP56300 Emulator v1.2.20 (VST2)

TEST 1
MIPS AVERAGE: ~504 MIPS

About the same MIPS average as @midi-man (i7-10700k)
His single CPU should be at least 10% faster then the 3900x and have higher MIPS then 3900x.

Anyone with a Ryzen 5900x or 5950x?
Would love to see the results
