Below are some tests that explain/show influence of MHz and Fast RAM to A500 speed:
Case 1) A500 7.09MHz 512 Chip + 512 Slow RAM = 553 Dhrystones (pic.1)
Case 2) A500 7.09Mhz 512 Chip + 1Mb
Fast RAM = 729 Dhrystones (pic.2) ... ~1.32 X Case1
Case 3) A500 14.18MHz 512 Chip + 512 Slow RAM = 602 Dhrystones (pic.3) ... ~1.09 x Case1
Case 4) A500 14.18MHz 512 Chip + 1MB Fast RAM = 1520 Dhrystones (pic.4) ... ~2.75 x Case1 (OR ~2.08 x Case2)
EDIT: In addition...
Case 5) A500 28.4MHz 512 Chip + 512 Slow RAM = 640 Dhrystones (no pic.) ... ~ 1.16 x Case1
Case 6) A500 28.4MHz 512 Chip + 1MB Fast RAM = ... In SySinfo this test goes crazy (over 3x A4000@25) ?!? ...
see EDIT3 below!
The test Case 6 was set to CE 8x speed (same as Case 5), so why it goes crazy, the reason cant be only because of Fast RAM ? ... test done with WinUAE2810b6.
EDIT2: If same test as Case 6 but with CPU 68020 instead of 68000 (or 68010) and it works fine !!! (SySinfo doesnt go crazy
)
EDIT3: With a lot of reluctance the WinUAE problem finally fixed (see post 11), so now is able to complete the test:
Case 3) A500
14.18MHz 512 Chip + 512 Slow RAM =
593 Dhrystones (no pic.) ...
~1.07 x Case1
Case 4) A500
14.18MHz 512 Chip + 1MB
Fast RAM =
1471 Dhrystones (no pic.) ...
~2.66 x Case1 (OR
~2.02 x Case2)
Case 5) A500
28.4MHz 512 Chip + 512 Slow RAM =
620 Dhrystones (no pic.) ...
~1.12 x Case1
Case 6) A500
28.4MHz 512 Chip + 1MB
Fast RAM = ... 2956 Dhrystones (pic.5) ... ~5.35 x Case1 (OR ~4.05 x Case2 AND ~2.01 x Case4)
