Yeah it is interesting. AMD IPC compares favorably to intel processors in some benchmarks and not in others. The example where 1st Ryzens are close in the performance to Sandy Bridge (of same 4/8 and close frequency). In DOSBox 2nd Ryzens are close to Sandy Bridge, so 1st may be below on ~10-15%. …

Ryzen can be sensitive to memory bandwidth. DOSBox test has low influence from a memory of modern PCs. With lower or higher memory clocks you should get the same results. You may notice, the previous generation as AMD FX also has lesser performance in DOSBox than Intel CPUs of near time. In single …

Ryzen R5 3600 @ ~ 4.15ghz Thank you. The improvement per Hz is ~15% compared to Ryzen 2xxx. Now it's close in DOSBox to Intel 4xxx at the same Hz. > A note on precision boost 2.0 - it oscillates clock speed between 4.05 and 4.2ghz constantly. 4.15ghz is pretty close to the average. It's close to …

Automatically changing settings for certain games is an interesting idea. Dolphin, NVIDIA driver, PCSX2 and Windows does this for example. The variety of Gamebase is the close example I saw for different retro platforms. For DOSBox specifically the needed settings were tested in ExoDOS. It's best …

There is one problem to use Ivy as retro PC. Such PC should work for longer than common. While those CPU have thermopaste under the cover (unlike 2xxx) which dry out, and the temperature should rise in performance tasks as games. Ivy is not significantly better in the performance, so 2600/2600k seem …

Finally upgrading my PC after many years. Going Ryzen 5 3600 ... I do a lot of emulation, so I am excited for the extra threads and increase in IPC. DOSBox bench thread (check my signature) lacks newer Ryzen 3xxx to compare with previous 2xxx. Would be interesting to see the results for Ryzen's …

For Windows XP support build I'd chosen Intel i7 2xxx with PCI motherboard. As this besides good compatibility also covers later games of 2010-... years (until PS5 generation). Videocards with good XP games compatibility should be until GTX 5xx . Taking DX11 games, you may prefer 9xx as the last …

Try different software environments (and mb emulator's builds) as they may affect the emulation speed. For example, 0.74 worked faster in XP (I booted it from a Live CD, mb Alkid's one) than in Win98 SE. "soon to be upgraded to a 1Ghz Coppermine/100mhz bus" If your video card will hold 83 MHz AGP, …

It's better to ask at nvidia forum, why their software breaks official builds of DOSBox. The easiest would be to use Daum's further, where the last version I'd recommended is that.
