68060 vs 68040

[mechy]

I just wanted to ask one simple question. I am planning on selling my 68030 to do an upgrade as the 68030 is too slow or me and the 16 MB RAM will not cut it, even for the Amiga classic.

The question I am asking is...is the difference in speed that much high in a 68040 @ 33 Mhz over 68060 @ 50 Mhz that it is worth it to skip the 68040 all the together and attempt to get my hands on a 68060 @ 50 Mhz.

SO much misinformation being thrown around in this thread. the MYTH that 060's all run cool is not true and all 040's run hot is pure BS.

What determines is a 040 or 060 runs hot is its MASK in most cases,not that it is simply a 040 or 060.

The mask is generally what size the transistors are in the chip at the time of manufacture and probably how much gate resistance the transistors had at the time,(rudimentary explanation but this is the easy way to explain it). As the years went on,the manufacturing process managed smaller and more efficient transistors in the package which meant they ran cooler in most cases.

I have 060 chips here you could fry an egg on and 040 chips here barely that run luke warm .

many AMIGA accelerators used early mask 040's and 060's and they run hot. I have had warp engine 040/40mhz cards that ran pretty cool.I have had a new 4060dt 68060 from softhut in the last years that could heat the house(they really should have a fan/heatsink with the old 060 rev they come with-at least the one i had).

example. a XC68060 with the early mask of 01f43g will run quite hot.the slightly newer one with the 01g65v runs less hot,and a brand new mask of 71e41j on a MC68060 will run very cool.

same with the 68040's  the chip i just desoldered off the 68040 apollo is a mask of 02E31F xc68040rc40M and runs very hot while the l88m mask 040 doesnt.There was even a 68040V that was 3.3v and ran fairly cool in its later masks but to my knowledge this was not used in any amiga accelerators.

So PLEASE quit spreading the nonsense that all 040's run hot and are unstable and all 060's run cool,. its simply not true.

Also many stability issues were caused by some Accelerators-*cough* apollo's *cough*(be it 040 or 060) having poor edge connectors and making bad connections. many 040 chips run no hotter than the some 030/50's.

To answer the original question: a 040/33 is good,but a 060 is better. go for the 060 if you can.

68040 is not good enough for what you would expect these days from your amiga:
- not stable enough due to considerable heat and heavy 5V need
- not powerful enough compared to a 50MHz 68060 by a 3 or 4 ratio
- not compatible enough compared to 68020/68030

You amiga needs either 68060 or 68030 for a smooth experience.

WRONG,WRONG,AND WRONG. there is absolutely nothing wrong with the 040.Read my previous message about whats hot and whats not.
Blame the poor A1200 design and voltage drop,blame poor A1200 psu's,blame bad apollo connectors and crappy accelerators,but quit spreading these myths that are not true.
See my explanation above debunking your heat sentence and the 040 does not use that much more power than a 030/50.have you even checked it?

 I used a warpengine 040/40 for many years,blizzard 1240,and cyberstorm 040 MKII and they were all reliable,ran at a reasonable temp,and it i didn't have compatibility troubles.Many 030/50's run hot enough to burn you when going full blast. Games can always be a problem because many bang hardware directly. this is the games fault,not the 040.
If anything the 040 is caught in the middle much like 2.x roms were.

Well, there is someone who is going to sell me an Apollo 1260 running at 80 Mhz with 32 MB of RAM maximum (unless I get someone to soldier an additional 32 MB of RAM).

But a Blizzard 1260 @ 50 Mhz can see up to 128 Mb of RAM but is stuck with 50 Mhz.

Is Blizzard 1260 higher quality and better than Apollo 1260 or do you recommend I should go ahead and buy Apollo 1260. This is my Amiga usage:

1) Internet browsing, IRC, etc
2) WHDLoad games
3) Playing MP3
4) Developing on it as a developer's enviornment
5) Using AmiGift

and I want to be able to play the game total chaos and Napalm as well. I love playing a game called Trap so the question is 32 Mb FAST RAM more than enough?

I also want to be able to watch movies on my system. So should I stick with Apollo 1260 with 32 MB of FAST ram at 80 Mhz or go with Blizzard 1260 @ 50 Mhz that can see 128 MB of fast RAM.

I am sorry,but i don't think you understand about the amiga here. The fastest 060 is still not going to exceed much more than pentium 1 90mhz performance(ok,overclocked boards may a bit). For watching movies like you do on the typical PC,divx,mp4,etc formats,a 68060 will not cut it. As a matter of fact one of Stans (stachu)Modified PPC cards would be the bare minimum. some exceptions for 060 are some Mpeg1 and 2 stuff,like video cd and svcd. You will need a board with good ram to do this more than likely.

I don't particularly care for the apollo design,but the boards do work and overclock far-some did suffer from bad edge card connectors though. the Blizzard 060's are rock stable in my experience and good quality.

On my cyberstorm PPC 060/66mhz 604e/233mhz with mediator and radeon i can almost watch a divx with sound,its like a fast slideshow though.

On a 1200 without a graphics card,you can forget it.The 1200 has many bottlenecks that slow it down compared to the typical A3000/A4000.

If you had a Delfina to decode the audio and you used the CyberstormPPC's scsi interface, you would have been able to watch lower resolution divx movies without any frame skipping.

I used to play divxs using the beta FroggerNG 2.08 WOS version.

thanks for the info,i will look into that! I use fast cf's via acard adapters on the UWscsi,which works quite fast so i am set in that respect.Its definately not a issue with moving data,just seemed to be lack of cpu.
