just wanted to create a thread of appreciation for the glorious DX 50, not to be confused with the DX2 50 (specifying for possible novices).
With its 1:1 FSB:CPU clock ratio, and, potentially the bus running at 50 MHz, I was always fascinated by this CPU!
However, it was too long ago, when I was just starting with computers as a mid school kid... so I can't remember very well, but I'm almost sure the DX 50 lived in the pre-32 bit buses (VLB and PCI) era.
So, my guess is that the ISA bus had no problems with that fast FSB, as it is simply stuck at max. 16 MHz, no matter the FSB speed. Am I correct?
So, no issues of cards stability.
At that point, the arising question is: what if there were any branded DX 50 PCs with a mobo built-in good vga? How fast would the GPU have been? Downclocked?
And, ISA bus aside, I also wonder how good the CPU-CACHE-RAM performances must have been...!
I wonder if there would be any VLB or PCI mobo which slots could be set at 50 MHz stably, with good VLB or PCI SVGA and EIDE/UATA controller cards (and of course Solid State Drives that can use that speed without bottlenecking), that would also be stable at 50 MHz.... Assuming it's possible, I wonder what the overall performances of the computer would be, a clean:
50 MHz peripherals • 50 MHz FSB, RAM, Cache, etc • 50 MHz CPU
in a perfect
against a system with identical components except a DX2 66 CPU, and, subsequently, everything beyond the CPU clocked at 33 MHz instead of 50...
Have fun wondering and commenting! (and, hopefully, even telling possible real experiences!).
Good luck for finding a DX50 CPU still around!!!!!
PS: for the same reasons, just in reverse, I never liked too much the DX2 50, and I particularly disliked the DX4 75 and the Pentium 75 CPUs... Come on... I can understand an FSB & rest of the system running at 25 MHz during the DX2 50 times... okay that's fair enough... but, still carrying around the 25 MHz bus during the DX4 and even the 2nd generation Pentium era?????
