AMD Duron 700 socket: Socket 462

What the Duron 700 is

The AMD Duron 700 is a 700 MHz single-core desktop processor from June 2000. It runs one K7 Spitfire core at 700 MHz with no turbo, so 1 core gives 1 thread. Cache is 64 KB of full-speed on-chip L2 with 128 KB of L1 on a 180 nm process. Power is rated near 31.4 W in a Socket A ceramic PGA package on a 200 MT/s EV6 bus with a 7x multiplier at 1.6 V.

A clean 7x integer ratio gives the 700 steady timing on first boards, which is why it became a common mainstream pick. AMD launched the Duron 700 on June 19, 2000 with the 600 and 650 parts. The chip supports MMX and Enhanced 3DNow.

Mainstream clocks with a 31 W envelope suit Socket A home towers with SDRAM and AGP graphics. That is why the 700 shipped in mainstream budget desktops.

Socket and motherboard compatibility

The 700 fits Socket A mainstream desktops with Spitfire support. It needs a 462-pin board with a 200 MT/s bus and a BIOS that lists Duron 700. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.

Mainstream SDRAM towers are the natural match. Boards listing Duron 700 accept the chip with a 31 W cooler.

Memory, PCIe and cooling

Memory is SDRAM through the board chipset, matched to the board sockets. The CPU has no memory controller. Mainstream boards commonly run PC100 pairs.

A 200 MT/s EV6 bus ties the CPU to the chipset, while AGP and PCI hang off the chipset. No PCIe lanes originate on the die. Cooling uses the Socket 462 lug clip with a 31 W cooler.

Upgrade paths

On the same socket, a move to a Duron 750 such as AMD Duron 750 keeps the board for 50 MHz more. A Duron 650 such as AMD Duron 650 drops 50 MHz.

A move to Athlon adds cache. The Socket 462 page lists the range for planning.
