-
- I recently ran benchmarks comparing an Amiga 4000 (25 MHz 040) to a 33
- MHz 486 from one of the big name clone vendors (Compaq?).
-
- The results were: on SpecFP (floating point benchmarks) the 25 Mhz 040
- beat the 33 MHz 486 by about 60%. On SpecINT (integer benchmarks) they
- were relatively close - the 040 was about 5% faster. This is similar to
- the results seen by magazines such as Tested Mettle when compating 486
- and 68040 systems. However, note that 486s come faster in clock speed -
- you can get a 66 MHz 486, but the fastest 040 is 33 MHz right now.
- These should be about the same in performance, with maybe a slight edge
- in integer performance to the 486.

-
- Sure, there are video cards up to 2048x2048 interlace or 1280x1024
- non-lace. However, 20" monitors of high quality are EXPENSIVE no matter
- which system you get them for.
-
- >3) How easy is the Amiga to program yourself? Are there REALLY GOOD

-
- Most people on the AMiga use C, but FORTRAN and BASIC are available, of
- course. The Amiga has something like 2500 functions available in shared
- libraries which you can access to do lots of neat stuff.
-
- >4) I've seen the wonderful graphics screens that Amigas can generate. How

-
- As a general rule, the Amiga software is cheaper for the same
- functionality - it has to be, given the nature of the Amiga market
- (lots of low end Amigas in Europe). Imagine 2.0 + Essence, while far
- from the best rendering package for the Amiga, is still quite good and
- costs around $250, while a package equivilant in functionality for the
- IBM tends to run close to $2000.

-
- The amiga does not, and has never suffered from the 640K bug that DOS
- has (or the 8+3 filename limit). You can access all your memory
- transparently. There are 64 Mb RAM cards available, and you can
- populate the 4000 motherboard to 18 Mb. There are even rumors of 512
- Mb RAM cards using 16 Mb SIMMS. You could, if you wanted, malloc()
- youself 31 Mb of RAM, and not have to address it in 640Kb chunks. VM
- is also available, but most people don't find it necessary due to the
- effeciency of AmigaDos. I have 9 Mb and I often have 6 or 8 major apps
- running - such as Imagine, DeluxePaint, a term program, a word
- processor, and GNU emacs, along with 30 to 40 smaller processes like
- screen blankers, snap utilities, etc. With all that I still have
- plenty of free RAM. And the RAM: disk on the AMiga is dynamic - it grows
- or shinks according to how much you put in it, so you don't have to
- waste RAM for it when you don't need it.
-
- > trivially use all 10MB at once (minus the memory used for the operating

-
- Yes - its all transparent. Has been since 1985 when the Amiga came out.
- NO extended/expanded memory managers or any of that. You can delare it
- all for an array, minus a few hundred Kb for the operating system.
