HOW FAST? Message-ID: <9106050110.AA13274@apple.com> Date: 5 Jun 91 01:11:18 GMT Sender: daemon@ucbvax.BERKELEY.EDU Distribution: world Organization: The Internet Lines: 42 X-Unparsable-Date: Wed, 05 Jun 91 08:55:05 SST Hi. After reading so many replies on my original question 'Zip vs Transwarp... which is better', I will settle down for Zip. This is because all of you who cares to reply say Zip is better, that is 100% agreement. So I assume Transwarp GS is an inferior product (at price/ performance ratio). But two things almost change my mind. The first is the report on that disgusting magazine A+/Incider. On the 4 reports they produce on a 10 MHz Zip with 64K cache, Zip is only slightly (2 seconds in some case) faster than the 7MHz Transwarp GS with 8K cache. A similiar report is on A2-Central (Title: The need for speed), where Transwarp GS beats a 8MHz, 16K cache Zip GSX. So I really wonder, is Zip really a faster board? It seems that Transwarp GS performs much faster on the same MHz and same cache configuration. The second point of view is my friend's experience who original have a Transwarp GS, but later bought a Zip GSX (8 MHz, 16K cache). He upgrade it to 64K cache, but found that in majority of the applications, he only have about 1 second gain. But later I discovered that he has replace 16K 70ns cache with 64K 100ns cache, and I am not sure whether it will affect the speed. I always believe that if a processor (in this case Zip GS) work faster than the memory can handle, the computer will crash, so since my friend's GS is working properly, it should means that Zip will works OK under 100ns or 70ns. The same reason applies for buying 150ns, 100ns, 70ns memory chip for GS, it won't increase the speed. But this is just my assumption. So, any comment? Anybody have actually perform some bencemark test on 1) Zip vs Zip on different configuration, 2) Zip vs Transwarp? I will appreciate any comments on my letter. *********************************************************************** *** Apple IIGS Forever *** An Apple IIGS lover from Malaysia.
