The K6 line was a functional CPU but I wouldn't call them "excellent". The K6-III was basically a K6-2 with integrated cache, much the same way the Pentium III was a Pentium II with integrated cache. Despite the fact that AMD tried to replicate Pentium branding on the K6 line, they very much competed with Celerons in terms of market place and performance.

Indeed that's how they were marketed where I worked (Office Max) and were priced and spec'd comparably to the Celeron based offerings from IBM, HP, and Packard Bell.

Another issue with the K6 line was they were always a generation behind at a time when Intel was rapidly rolling out technologies like MMX and SSE. Intel coordinated with software manufacturers and had launch day examples that presented significant performance gaps between the CPU lines.

The K6 also had a shorter execution pipeline than Pentium so it struggled to hit 400mhz when Intel was approaching 500mhz. That's why the Athlon was such a shock because it arrived at 700mhz and stomped everything.

Looking back at the K6 line now, they likely perform far better then they did at the time because software eventually got around to supporting the hardware.

Minor correction. Athlon arrived at 500MHz, 550MHz and 600MHz. But they were still a big shock when they arrived. They were the first chip in a long while to really take on Intel and succeed.

The 650MHz came two months after than, and 700MHz another two months later. 6 months later 1GHz! It is easy to forget just how rapid performance increased in the late 90s.

I'm trying to reconcile that with my memory. Pre-launch the AMD rep approached the electronics salesmen where I worked and offered us a deal to purchase a K7 700mhz for like $200. It came with a Biostar motherboard, a brand I'd never heard of back then.

I remember it was a K7 700 because it was the first from scratch PC that I ever built. Everything before and probably since has been a Ship of Theseus.

Athlons official announcement June 23 1999, official shipping date August 17, 1999. A week after announcement reservations started at Akihabara https://akiba-pc.watch.impress.co.jp/hotline/990703/p_cpu.ht... https://akiba-pc.watch.impress.co.jp/hotline/990703/price.ht...

"AMD Athlon 500-600MHz (bulk) price display. The product is scheduled to arrive in mid-July, and reservations are being accepted. However, there is no specific arrival schedule for compatible motherboards yet."

"the K7 revised "Athlon" has been given a price and reservations have also started. The estimated price is 44,800 yen for 500MHz, 69,800 yen for 550MHz, and 89,800 yen for 600MHz."

Those were Pentium 3 450-550MHz prices.

A week before official AMD shipping date retail Athlons arrive in Japan https://akiba-pc.watch.impress.co.jp/hotline/990813.html

"AMD's latest CPU "Athlon" will be sold in Akihabara without waiting for the official release date on the 17th is started. All products on the market are imported products, and 3 models of 500MHz/550MHz/600MHz are on sale. The sale of compatible motherboards has also started, and it is possible to obtain it alone, including Athlon"

~$380-800 depending on speed.

For reference in US 4 days later on August 17 Alienware was merely teasing pictures of Athlon system https://www.shacknews.com/article/1019/wheres-my-athlon According to Anand "OEMs will start advertising Athlon based systems starting August 16, 1999" https://www.anandtech.com/show/355/24
