The Intel processors are a good choice for Intel-designed systems; this is because you most likely do not need a BIOS upgrade for an Intel processor.  When adding Intel MMX processors to older systems, you will want to check the BIOS for MMX compatability.

The bad part about the Intel processors is that Intel has abandonded the socket 7.  This means that there are no more upgrade options avalible from Intel beyond their 233 MHz processor.  There is talk about a 266 MHz Laptop socket 7 processor, however it is uncertain when it will be released and if it will work with the PowerLeap adapter.

I installed a PL-PRO/MMX with an Intel 233MHz MMX processor and here are my results.  They show that the PL-PRO/MMX with an Intel 233MHz MMX processor is a good choice for upgrading a PB 640 motherboard.  This upgrade also works with many other motherboards.

I was more than pleased when I saw my Wintune 97 results; both the CPU Integer Performance and the FPU Floating Point-Performance had significant gains.  I put the Wintune results for a PB 680 200 MMX system in for a comparison; I would have included another 233 MHz system for comparison, but my Wintune Project has yet to receive results from a 233 MHz system.  A great side effect of this upgrade was that my video performance increased; see my Stealth II S220 Page for details.

The above chart shows that my system went from 241 MIPS with a Pentium 133 to 435 MIPS once the PowerLeap adapter with an Intel Pentium 233 MMX was added.  This was an increase of 195 MIPS.  As you can see, a standard Pentium MMX 200 MHz has 354 MIPS and the 233 performed significantly better than the 200 MHz, as it should.

This second chart shows how the Floating Point Performance went from 70 MFLOPS with a Pentium 133 to 131 MFLOPS once the PowerLeap adapter with an Intel Pentium 233 MMX was installed.  This was an increase of 61 MFLOPS.  As you can see, a standard Pentium MMX 200 MHz has 114 MFLOPS.  Again, the 233 Pentium outperformed the 200 MHz Pentium, as it should.

If you think these results look good, then you should try using my system.  I have seen noticeable improvement when using my system.  Other increases were also seen in the Memory I/O and Memory Read; this is most likely due to the higher CPU speed and the extra bit of L2 Cache found in the Intel MMX chip.

If 233 MHz is still not enough speed, you will want to check out my review of the PowerLeap Adapter with a K6-2 300 in part 3 of this review.
