Sorry. I got confused because I forgot in Europe the decimals and commas are reversed 😁

No problem 😀

Now I am really satisfied of performance but with more RAM I could play more games... almost all dos games of 1995-96-97 requires 8MB

The Cyrix 486 chips were said to be 5-10% slower than the intel parts at the same clockspeed.

The DX/2-50 will be a little faster than the DX-33 at CPU intensive things, but fall behind at I/O intensive stuff. I remember reading the reviews in PC World and PC Magazine in early 1993, and those two CPUs were roughly equal.

I've reinstalled the 486DX 33MHz for try bios configuration

Doom result 35x1091/2050=18,62 fps..

same of Cyrix DX2 50MHz

EDIT: SpeedSys drops from about 20 to about 12 points

Speedsys apparently isn't a very accurate tool for measuring CPU speed on older systems. The DOOM result is probably more useful for performance comparison.

I have numbers for Intel chips, Phil's test suite :

Speedys, 3DB, PCPB, Doom, Quake

1DX-33  : 12.39   28.2	 6.6	16.11	3.9
2DX-50  : 18.59	41.2	 9.7	23.60	5.7
3DX2-50 : 18.58	38.6	 9.0	22.41	5.4
4DX2-66 : 24.78	51.6	12.0	29.70	7.2

and, for completeness :

1AMD DX4-100 V8T :   37.09	67.1	15.9	39.81	9.7
2Intel DX4-100 WT :  41.88	71.9	19.8	42.68	10.4
3POD83 WT :          ???     68.5	18.6	41.73	16.1

with ET4k/w32p on MB1433/50UIV-A.

thanks for the informations

I want to try soon the phil's test suite

in the meantime I found another 4 1MB modules...! With 8MB I can install really many games / software 😀

EDIT: First two games with 8MB of ram.. Dark Forces (really playable) and Grand Prix 2 (slow with details to a minimum)
