Re: AMD K6-2 equivalent to pentium......
Posted on 2019-07-10, 07:34
I would say something like Pentium II 300 MHz in integer operations and Pentium II 266 MHz in a floating point use.

He's probably refering to the increase in performance from 160 MHz to 200 MHz. From 133 to 160 give you a boost of 20%. From 160 to 200 gives you an additional boost of 25%. Now 25% may or may not be marginal, depending on your notion, but keep in mind that almost every VLB card requires to set a …

Also, normally only one VLB card will work at that speed. If you have more than one VLB card installed, 50 MHz is normally a no-go, as it either doesn't work at all or very unstable. Mine is stable at 3x50 MHz with two VLB cards; a video and a multi i/o. I had to lower the DRAM timings a bit though …

Difference in performance is negligible between 4x40 and 3x50, with lower DRAM timings and VLB WS 1 for the latter. Exactly. Going from 40 MHz FSB to 50 MHz won't give you any magical boost. 4x40 is clearly the better option.

Just go socket7 with a p200 and be done with it?

I have mine(ADZ) booting at 200 and working at 180(tested thoroughly without any error in DOS and Windows). It runs at 180 with just 3.6V and no voltage enables it to run with 200 as it does not even boot at anything over 4.5V. On the contrary one intel DX4 runs at slightly below 5V@133 without …

My guess would be K5 was seen as a necessity because Socket 5 was hot stuff. The platform was much improved and K5 had the potential to beat Intel. It's just unfortunate that they apparently didn't have the resources to get K5 working in a timely manner. It's doubtful they knew it would be so …

and skipped k5 going straight to k6 They didn't skip anything. To begin with, K6 was not their design.

I did not find much of a performance increase going from 133mhz to 160mhz. So the performance increase is going to 200mhz will be marginal. The bump from 133 to 160 on the retired 5x86 I had from work back in the days, when my main rig was a Celery 300A@450, a just what was necessary to play music …

I have mine(ADZ) booting at 200 and working at 180(tested thoroughly without any error in DOS and Windows). It runs at 180 with just 3.6V and no voltage enables it to run with 200... What is the datecode on that ADZ chip? Is it stable running games in Windows? How many chips did you need to try to …
AMD 5x86 P75 without heatsink?
Posted on 2019-07-12, 15:56
i have read in many places that this chip can work without cooling system... is true? Mine is labelled on top “heatsink and fan required” 😐
Re: AMD 5x86 P75 without heatsink?
Posted on 2019-07-12, 16:08
You pretty much always need a heatsink and a fan is highly advisable if the heatsink isn't particularly big. These chips do get pretty hot even at 3.3V.

ok i get it, as soon as i can unplug the DX2 I see to insert the 5x86 and try to see how it works. tnks guys
Re: AMD 5x86 P75 without heatsink?

You need a board capable of 3.3V before you can use the 5x86. Chances are that your board is 5V only and that will fry the 5x86 sooner or later. Can you show a photo of the board ?

My board is capable for sure, the only cpu that can’t handle is the Pentium Overdrive. Is a SBC 486 really good equipped. The only bad thing is that not have a ZIP Socket and i must use some tool to detach the DX2 Cpu that is actually inserted

Instead of a 5x86 at 200, if you want to get your fast 486 dose, you can always try a Cyrix MediaGX. I happen to have a MediaGXm 266 that runs happily at 300MHz, made for some interesting comparisons with a Pentium 133 :). Is there a thread on this? Which motherboard are you using for this? None of …
