That's right. The X86/64 has the biggest grip, and no other system is close to it.
B450PRO+R3800X: It has UEFI+Legacy support in BIOS, and DOS runs great on this machine.
But how is video support? Are VGA modes supported (320x200,320x240,640x350) as well as VESA modes on the R3800x onboard video? What is the onboard sound chipset? Is it compatible with SBEMU?
R3800X CPU without APU. It contains GTX1650 (Win10-11) and NV7900GS (DOS, Win98, XP).
The motherboard sound sounds( Realtek S1200A) with SBEMU/VSBHDA DOS sound 6.22/7.1 ok, and has a rotated SB Live with Chinese PCie to PCI converter, but also for Win98 mainly because it doesn't have SBEMU, but it works with its own driver.
NV7900GS : VGA modes supported for DOS (320x200,320x240,640x350) as well as VESA modes ok, and even larger resolutions.
The 3 body problems cannot be solved, neither for future quantum computers, even for the remainder of the universe. The Proton 2D is circling a planet and stepping back to the quantum size in 11 dimensions.

I was never able to get SB16 emulation working on pre Zen AMD APUs, so It's surprising to see it working with Ryzen.

Outstanding! Thanks for the screenshots and the information. Seems like it would indeed be very near the "fastest" and most modern CPU / mobo combination which will run DOS on bare metal very well. Noted with relish for future reference.

I do not admire it, many of the previous motherboards can be a problem. It is already free blocks on NFORCE chipset, but the EMM sheet frame is flawed due to the boldness of the BIOS.
I used to start experimenting and then developed the fake sheet frame. EMM indicates a mistake, but goes on, but the page frame will be active on a modern machine, so it runs on the Zen2 under the method of SBLIVE DOS (SB DOSdrivers). As well as native EMS -loving, non -loving titles too. My invention.

There are also a couple of Alder/Raptor motherboards, which have a inherited code in BIOS, and DOS runs with an older secondary video card. Anyway, even in the GTX1650, there is a inherited code, DOS runs, if I allow it in BIOS, there is no longer in the RTX series.
Alder/Raptor+inherited code: Win98 also goes up with a secondary NV7900 video card, a protection error may come, but it has been corrected with Cregfix. I've seen someone packed on Raptor.
DOS/XP: HD6870 and GTX560Ti, these go - of course not under Win98 anymore, there is the last driver for the 7900 series.

I'm impressed, you should start a new thread about this creation of yours. SB16 emulation on Ryzen is good news.

In the Hungarian topics, development is scattered in DOS6.22/7.1/Win98/XP.
If I wanted to get together - dos about 4 A4 pages, win98 10 pages.
I plan, but it is quite complicated, so I saved the final versions into ISO/IMG File, because I don't certainly remember everything over the years.
DOS6.22/7.1 IMG in the cloud, but not link here, because dos is a license for today's day. No one is interested today, but here the moderator is strict.
ETC for a variety of modern machines:

If using a Pentium or any CPU that includes VME and loading EMM386 you will lose around 30-35% of your fpu performance in Dos when CPU is in V86 mode.
To get the real speed use JEMM386/EX to switch to protected /V86 mode as it does support VME.
I tested this on a Core2 in NSSI using its benchmark. The latest 1999 realease of EMM386 still does not support VME.
I love how after all these years, I keep learning new things about DOS in this forum. Thanks for sharing this.
Are there any EMMs that support both GEMMIS and VME? Later versions of QEMM perhaps?

I wonder why this would be the case. Maybe the NSSI FPU benchmark does weird things like triggering exceptions or messing with the interrupt flags all the time…
Also, I cannot think of a single piece of software where this would even matter. Maybe Excel 2.1 on Windows 3 in real mode? Come on!
With a Intel 13700k with stock settings, I got :
Landmark (6.0 from phil's distribution)
CPU 23400 Mhz (no difference between real/v86 mode).
FPU 12000 Mhz
Video 26568 chr/ms
AIDA16 (from this thread):
AIDA16: 1266 (in real mode) , 1283 (in v86 mode with JEMMEX)
AIDA32: 16424

The software/programs don't need to support VME, the CPU just needs it to be enabled, which EMM386 and any version of Win3.x will not, so you will get a slowdown in anything that uses V86 mode.
Loading Emm386 will generally slow down everything in DOS by 25-35% (video, i/o performance, FPU) . NSSI benchmark is just an easy way to show it as a real time bar graph. It is the same with other dos benchmarks/games. The same whether using a 486DX4 or Corei7. The only difference is the slowdown is much more notable on a 386/486 versus a 3GHz core i7 slowed down by 25%.
This was well known back in the early 1990's when using a 386 and 486 as it had such a big impact on performance. Most people just loaded Emm386 in their autoexec.bat and didn't even know that it switched their CPUs to V86 mode and the slowdown it causes. There are many posts on Usenet around 1992-1995 about it.
E.g :EMM386.EXE slows down the computer: Why? (1994) (click on expand all to read all the replies) https://groups.google.com/g/comp.os.msdos.pro … /m/c3xCtEab8c4J
Intel created VME to address the slowdown, mainly optimizing virtual interrupts. Emm386 though never added support to enable VME when switching to protected mode/v86 , you will still get the slowdown on a Pentium. Jemm386 has a switch to enable VME, in tests I've run with VME enabled the slowdown in V86 mode is then only around 2-3%, instead of 25-35% with EMM386.

Compare the benchmarks by using Emm386 for V86 mode and then using Jemmex for V86 mode (VME are enabled by default with Jemmex). You should see a slowdown with FPU in emm386.

It is not particularly important on a beast machine. Because of this, I run DOS with Xeon/Ryzen CPU, for example, Q2DOS is also a smooth SW render for to high resolution.
The 3 body problems cannot be solved, neither for future quantum computers, even for the remainder of the universe. The Proton 2D is circling a planet and stepping back to the quantum size in 11 dimensions.
Interesting so an Intel 13700k looses to a Core2 Duo E6600?! crazy!
This is because the AGP motherboard and the R9800Pro contain even legacy code, and the more modern Intel 13700K system can only rely on emulations.
So I don't update the Zen2 BIOS, and I use 7900GS and HD6870 secondary video cards in this + in Haswell Xeon, so allow there is a legacy code.

The final config is built with NV6800GT, making it even faster. The secondary video card is the Matrox Mill G200 for certain DOS titles, and too Win3.11.
