Taiwanese Apple Macintosh cloner Umax Computer Corp believes the addition of the Umax CacheDoubler will make its Apus series of desktop Mac Operating System computers the fastest Mac clones in their class. The CacheDoubler contains technology that enables the normal performance of its 240MHz processors to be increased, enabling faster access to cache by bypassing the system bus. Umax says it also means system resource contention present in other machines is avoided, improving performance by up to 30%. Umax says the CacheDoubler runs at 80MHz, and claims it is twice the speed of other system components, residing between the processor board and the motherboard. The Fremont, California-based firm cut prices by between seven and 20% earlier in the year (CI No 3,103). CacheDoubler is due out in mid July.
