My goal = 200 MHz

Post by EKSUHLUHNT »

My specs :
Intel Xeon E3-1240L v5
4 Cores
8 Threads
L1 4x32 + 4x32
L2 4x256
L3/L4 8M
2.1 GHz Turbo to 3.2 GHz

DDR4-2133
Clock 1067 MHz
4x4GB @ Dual-Channel

AMD Radeon RX 6400
4GB GDDR6

I'm guessing the mainboard doesn't matter, but I am trying different boards. is there anything I can do in the bios to help to achieve full emulation?
CPU I'm guessing a regular Pentium 200 is easier to run versus a Pentium OverDrive or the Overdrive MMX correct?
The biggest confusion for me are the Video cards and I've tried so many-- so I basically want to know what are the easiest to emulate
I'm running Windows 98 SE with the goal game Magic & Mayhem which recommends 200 MHz and the Minimum is 133 MHz
I'll probably end up upgrading my CPU anyway since this is the weakest that the board can accept.

The only thing that really matters is the single core speed of your host CPU, and 3.2 GHz turbo is fairly low.

I have an i5 6600 (released a year after your Xeon) that has a turbo of 3.9 GHz and it can sometimes run at full speed with a Pentium 200. It entirely depends on the game.

It doesn't matter what settings you change in PCem - if you don't have the processing power, it won't run at full speed. The CPU emulation is by far the highest load on the host, so you're probably not going to get there by fiddling with video cards or motherboards. If the game can run on a Pentium 133, then I would target that and see what kind of performance you can get.

Your current CPU probably can handle a Pentium 133, but the only way to make sure is to test it yourself. While running PCem, check "CPU time" in the Machine window. When it goes past 100%, the emulation speed will drop.
Pentium Overdrive isn't really different from a regular one. What matters is the emulated frequency of the model, e.g. 133, 150, etc.

If you plan to upgrade the CPU, get the one with the highest single-core performance.

There isn't much of a performance difference between video cards when running 2D and software rendered 3D games. I usually go with an ATI Video Xpression. For accelerated 3D games, the options are basically all Voodoo. There are Virge models but they are quite bad in comparison, in both performance and game compatibility.

The comfortable clockspeed on a 201X Intel Core processor that can reach 200mhz emulation's usually 4ghz. 4ghz was a very common stable overclock as well, but that's relegated to "K" processors. (2500k and up etc.)

3.2 Ghz was typically enough for a Pentium 90 or Pentium 100, but that was 5 years ago. If you can run a Pentium 133 on 3.2 Ghz today then that would be really good.

I agree with leilei, you will need a CPU with an all-core turbo speed of at least 4 Ghz to get a Pentium 200. Today you should aim higher than that. If you are looking for a new budget PC, try to select a CPU that can run a Pentium 233 MMX or even 300 MMX at 100% performance. I recommend Intel over AMD.
