teckel12 This was a big deal, I received a 1 GHz Athlon mouse pad as some advertising promotion. Meanwhile, I was running some slow 133 MHz Cyrix clone 6×86 (M1) CPU that constantly overheated trying to play Quake. But, I had the 1 GHz mouse pad. Reply

thestryker EzzyB said: This resulted in one of the most unusual CPU releases ever when, to get to 1Ghz, they released the Intel Tualatin processor. (Note that Tualatin was NOT Coppermine) Coppermine hit 1 GHz fine it was the 1.13 GHz model which didn't work right and had to be recalled. I believe they eventually released one or two above 1 GHz but it was largely irrelevant by that time. EzzyB said: It was technically a server chip, though the Xeon name hadn't been used at that time. There were multiple Tualatin CPUs and the server ones were named PIII-S. I have my dual PIII-S 1.4GHz system in storage as I have lots of fond memories. EzzyB said: actually had hyperthreading None had hyperthreading, but they did support dual socket configurations. EzzyB said: While it used the same socket as the P-III it needed a different chipset that enabled an additional pin in the socket. It wasn't an additional pin, but rather a shift of what the pin did. I want to say it was one of the power delivery pins holding a different value. EzzyB said: Overall the chip ran quite well and compared to the Athlon and P-IV right up until you did something memory intensive (similar to Athlon) and then the higher bus/memory speeds of the P-IV would kick in and it would prevail in memory intensive stuff. My system used a Via Apollo chipset with DDR support. While I picked it because I was using dual CPUs and they shared memory bandwidth it also had advantages on memory intensive software. Reply

warezme OMG, I had totally forgotten Slot A! Dang blast from the past. I remember having one of those. Reply

80251 DEC's Alpha was the first Ghz. CPU and it predated anything from Intel and/or AMD. RIP DEC. Reply

You nailed just about everything I was going to say. I would only like to add that the Athlon/P-III didn't "choke" because of lack of memory bandwidth. The P4 wasn't really a bandwidth monster until the P4C anyway (excluding horrible RDRAM). The P4 simply needed that bandwidth to keep its long pipeline full especially after mispredicts. What the P4 did do very well eventually was SSE2 once software caught up. Athlon/P-III lacked it and it was a huge step forward from 3DNow!/SSE in many areas. Media transcoding comes to mind. Reply

razor512 Due to pricing back then, I had to settle for an anemic AMD Duron CPU back then. The design did pretty well for bare die cooling. https://i.imgur.com/m0h5OVW.jpeg Reply
