Intel Introduces 533MHz FSB CPUs - Pentium 4 2.53GHz

Intel 850E Performance

Before we get to the actual CPU performance tests, let's have a look at what sort of improvement to expect from the 533MHz FSB and what sort of gains are in store if you explore PC1066 RDRAM as an option as well (note that we ran all of our CPU tests with PC800 RDRAM):

With a performance gain ranging from 0 - 12%, the combination of PC1066 RDRAM and the 533MHz FSB is a valuable asset for the Pentium 4. As clock speeds increase, the assets will definitely grow in value to the point where we'll quickly shun the older 400MHz parts.
