This CPU is performance-wise identical to this 850MHz mobile Duron except that it is based on the Palomino-core with disabled L2-cache. You can see the visual difference: the Palomino (like this one) is square whereas the Morgan is rectangular.

Another difference is the vCore that is lower on this CPU. > Read more

Released on January 30th of 2002 for use in budget notebooks. Partly due it's low 1.5V vCore it fits within a TDP (Thermal Design Point) of 25W.

I have questions regarding the core of this CPU. It appears to have the same 'die' as the Palomino (used for the Athlon XP and Mobile Athlon 4). I'm unsure if this CPU uses a real Palomino core (with disabled cache) or that it uses the 'Camaro' core. Often you'll find references to a 'Camaro' core for the second generation Mobile Duron's but I'm unsure if this name is correct. I tend to treat this CPU as a Palomino CPU rather than Camaro.

I remember that this CPU (due it's unusual form; a Palomino shaped core but marked as Duron) was an item of discussion in it's day. Before it's release a picture popped up on a forum which was highly debated for it's authenticity. Back then it was stated it was a fake picture but it turned out to be the real deal. > Read more

Just like my other Duron 1300 but 7 weeks older. > Read more

An uncommon CPU. Most Duron's at 900MHz are based on the Spitfire core (which is the budget version of the Thunderbird core). When AMD shifted to the Palomino core (for use in their Athlon XP processors) they also created the Morgan core for the new Duron processors. Often you'll only find Morgan CPU's clocked past 1000MHz. References at AMD always mentioned 900MHz and 950MHz 'Morgan' parts but I never saw them in the flesh nor noticed people on forums who owned one. Now, about 14 years later, I obtained one.

It's OPN (Ordering Part Number) is DHD900AUT1B. The regular 'Spitfire' Duron 900 has OPN D900AUT1B. Another twist can be found in the OPN of this CPU: Morgan's all have OPN's ending with AMT1B rather than AUT1B. The difference is that U is used on CPU's configured for 1.6V and that M is used for the higher 1.75V. Back in the day this was one drawback of the new Duron 'Morgan' because every hoped it would use a lower or at least an equal voltage compared to the older Spitfire generation but this was not the case. Higher voltage means more energy consumption and more heat output. > Read more

The fastest breed of the Morgan-based Duron's. These CPU's ran quite well back in the day and paired up with DDR-SDRAM memory and a decent harddrive it was easily faster than a vastly more expensive Pentium 4. > Read more

I always thought that the slowest/first Duron 'Morgan' ran at 1000MHz, until I saw the original specification from AMD which also mentioned a 900 and 950MHZ model. However, it took about 14 years for me to see a 900MHz Duron with Morgan core! > Read more

Technically the same as this Mobile Duron 850 because it has the same 'Morgan' core. In this case it's a desktop CPU with a multiplier lock so the clock frequency can't move past 11x100MHz (1100MHz) unless you unlock the multiplier or adjust the front side bus (FSB) manually. > Read more

A mobile version of the Duron. This one uses the 'Morgan' core and runs at 850MHz. Normal desktop Durons with a Morgan core can only be found starting from 1000MHz up to 1300MHz with increments of 100MHz. Because the Morgan core is newer AMD used it for the mobile versions and clocked it down a bit so energy consumption will be reduced. Of course the vCore is lowered too.

The Mobile Duron also has PowerNow! which is a technique that saves power. In case the CPU doesn't have to do anything it clocks down to 500MHz at 1,2V. In fact this is not a specific CPU feature but the mobile versions have an unlocked multiplier and the motherboard will take care of the multiplier and voltage. > Read more
