| We did a performance comparison between the various 68K CPU models. As benchmark we measured CPU video decoding performance. Without showing/rendering the video. So the test is a pure CPU calculation comparison. The equal test conditions on all systems are: > riva0.52 verbose noaudio norender noskip FPS=1000 ram:TopGun_640x360.mpg Used files RIVA 0.52 EXTERNAL LINK Testvideo CLICK HERE Results: A1200 with 68030@33 MHz == 2.0 FPS A4000 with 68040@25 MHz == 2.9 FPS A4000 with 68060@60 MHz == 13.7 FPS A500 + VampireV2 68080@78 MHz == 47.5 FPS A500 + VampireNG 68080@93 MHz == 61.7 FPS
This means the VAMPIRE V2 (78 MHz) does perform this test like
68030 @ 795 MHz 68040 @ 409 MHz 68060 @ 206 MHz

| I think you missed the FPS number of the VampireV2.

| 51.8 FPS?

i suppose you meant "68060 @ 206 MHz" right ?

Gunnar has made that typo. But yes, soon we should advertise it as 060 200Mhz+

No, because that would be a lie. It is not an 060 and is not clocked at 200+ MHz.

| the latest riva uses ammx instructions when ran at a vampire. So it wouldnt be fair to call it a 68k comparison test. Ammx handles data magnitudes faster than "vanilla" 68k. i think this is comparing apples and oranges. however it is a good test to show the advantage of the ammx instruction set. Sorry for the negativity, and possibly ignorance.. ;)

| Yeah you make a fair point Aksel, but as you say yourself, Vampire/Apollo is more than the raw power, and for a real test you have to include that aspect aswell. Thanks for posting the performance data.

| how about running the same tests on the "old" riva, with no ammx support..

While that is intresting from a pure academic point of view, for real world usage, the best possible performance while retaining the same quality is what seems more intresting. I have very little intrest in converting my videos so it can run on my 030/50 for example. Even downgrading them to run on the current performance of Vampire I find "meh", so what I personally want to know/see is the advancements in decoding, which includes ammx. Its like comparing 2 aircraft, one single engine, and the other multiengine. I dont feel its fair to ask the crew to shut down one of the engines for them to have the same playingfield :P (I know, the multiengine will have performance penalities due to the drag and asymetric thrust effects too, so not perfect comparison).

| I dont care about watching videos on 68k or vampire.. (who would? :), so it would certainly be just for an academic point of view.

| Aksel A: But plenty of others want that option. Me included. So why even mention it?

| :) Welp. Sorry for "bashing" on you Aksel. I merely suggested the optimal performance for each platform is what seems to be the focus. I guess people can freely add non ammx stats too, for comparison.

np.. i thought the topic was " Comparing 68K Family Performance ". :)

| Well, in fact the title of the thread might be misleading. While it is true that this is real life comparison it should be got for what it is: comparing Vampire vs Old 68k family while decoding an MPeg file. This does not for sure give any index of the 080 Vs 060 computing power with software that does not use AMMX. Said that, I do not see a problem with that, since we all know things vanilla and Apollo related. Have fun!
