The K6-III skirts around this problem by incorporating 256k of L2 cache directly onto the CPU itself. Now the L2 cache is running at full CPU speed, or in this case 400MHz, about 6x the speed of the L2 cache on those old 66 MHz FSB motherboards. Because of these advancements, PowerLeap chose the K6-III for their latest CPU upgrade product designed to upgrade old Pentium systems. Good Tech Support Solid Product - Price Limited to motherboard currently in system. Overall An easy upgrade for those that are too leery of popping the motherboard out or that just simply like their current motherboard.
Performance is above average, but still depends on system components.
The adapter was accompanied by an adequate manual with detailed text and visual aids for installation and setup. However, it is noticeably lacking when covering the CPU Control Panel as discussed below. If you have any questions about it, check out the PowerLeap website . Also included was a PowerLeap Utility disk, containing their CPU Control Panel v4.0 program which determines, as well as it can guess, what kind of CPU is in the system and the CPU's approximate speed. The interesting part of this program is that it allows the user to adjust certain options specific to their CPU such as different caching methods.
