I ordered a new, ceramic and gold MC68010 to go in my Amiga 2000 as I remove the A2620 '020 board due to issues with some tightly-coded old and new OCS/ECS demos (my main use of the system). I came to realize some of these issues would exhibit with the '010 as well, and for very little performance gain.

And so, the loveld 68010 may become one of my "desk chips" to glance at from time to time as I do my thing at the desk, like my lovely ceramic and gold Freescale '000.

I am considering the configuration of my Amiga 2000 w/ 68020 accelerator... I would appreciate opinions from drivers of slotted Amigas, here.

I have an Amiga 2000 with SCSI + SCSI2SD, 4MB 16-bit FAST RAM, 1MB CHIP RAM, etc. It also has an A2620 68020 accelerator (14MHz) with 2MB 32-bit FAST RAM which is meager, but makes things noticeably faster on the Workbench. Most of what I do on this is watch demos and play games, though. All I do on desktop, really, is use AmiTCP and ncftp to bring files over and run IMP sometimes.

I recently downloaded the Amiga demo 'Downslope' and noticed it's less fluid / smooth with the accelerator enabled. I've seen this before here and there, but assumed that the accelerator was doing my a solid in demos - giving a bit of a boost.

I commented about this in the Pouet 'Downslope' thread and the developer came in and commented,

---
"Accelerators often introduce an asynchronicity between CPU and chip memory, which adds to chip access latency.
This can be worsened by the occurrance of many interrupts, which can cause additional strain on memory on a higher CPU.
If we are unlucky, not even the much faster execution time of the higher CPU can make up for the additional latencies and strain on chip memory.
It's a matter of focus on the target. There are side effects on higher CPUs which are difficult to anticipate, and usually you have only a limited number of machines for testing."

This makes sense, I suppose. Is this common? Are people with '030, '040, '060 accelerators having a lesser experience with demos due to CHIP RAM latency than with base '000? Certainly in some scenarios the more powerful CPU helps hugely for demos and games alike - I've seen this on my '020. But, yes -- demos are the most tightly coded of all Amiga apps, certainly. To the metal, etc.

So I am wondering now, should I remove the accelerator to get the most out of OCS/ECS demos on the system? Yes, I can disable the accelerator with a right mouse click at reboot, but that gets in the way of keeping Degrader's PAL state in effect, causing a hassle. (it's an NTSC A2000, unfortunately).

Anyone been down this road? Thoughts?

Picture proof that Aliens used Commodore AMIGA A2000s. These sort of Aliens could also eat sandwiches cat.
