Final 604e Power Mac. Replaced soon after by the dramatically faster G3.
The 7300 was the last of the beige 604 towers, and the most sorted. February 17, 1997, a PowerPC 604e between 166 and 200MHz, Mac OS 7.6, three PCI slots. The 604e was the 604 with a bigger cache and some architectural tidying, and the difference showed up in ordinary work as well as in Photoshop filters and rendering, where PowerPC had always done well against Pentium and Pentium II machines. Nothing about it was exciting. That was the point. The 9500's launch had a logic-board recall and the 8500's AV hardware frustrated people for years, and the 7300 had neither problem. It arrived months before Apple's roadmap turned to the G3, which makes it the end of the 604 line. Because the processor sits on a card, owners could later fit a G3 upgrade and did, in large numbers, which kept these towers useful well past their expected life. Creative professionals, schools and prosumers bought it. Then Jobs came back and Apple's product line went from a dozen confusing towers to four boxes.
The PowerPC 604e was an enhanced revision of the 604 core featuring a larger on-chip cache and refined execution pipeline, delivering a noticeable performance boost per clock cycle over its predecessor. Running from 166 to 200MHz in the Power Macintosh 7300, it delivered strong performance in professional applications and held up well against contemporary Pentium and early Pentium II desktops in floating-point-heavy benchmarks. It represented the final major evolution of the 604 family before Apple transitioned its entire lineup to the PowerPC G3 later in 1997.

1997
Shipped with the Power Macintosh 7300 at its February 1997 introduction.

1997
Brought the new Platinum appearance and multithreaded Finder.

1997
Widely regarded as the sweet spot release for 604e-based Power Macs.

1999
Ran acceptably with a G3 upgrade card installed, though unsupported on stock 604e hardware.
The 7300 was well reviewed as a mature, dependable mid-range Power Mac, though some in the press already sensed the G3 transition was imminent.
The 7300 is the most refined PCI Power Mac yet, with the 604e chip giving a real speed bump over last year's models at a reasonable price.
For creative professionals not quite ready to spring for a 9500, the 7300 delivers excellent value and credible performance against Pentium II desktops.
Floating-point performance remains a PowerPC strength, and the 604e chip in the 7300 continues that tradition against Intel's latest offerings.
A solid machine, though buyers should know the G3 wave is coming; those who can wait a few months may want to hold off.
