AMD Duron 800 socket: Socket 462

What the Duron 800 is

The AMD Duron 800 is an 800 MHz single-core desktop processor from October 2000. It runs one K7 Spitfire core at 800 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 35.4 W in a Socket A ceramic PGA package on a 200 MT/s EV6 bus with an 8x multiplier at 1.6 V.

A clean 8x integer ratio at the top of the early Spitfire set gives the 800 steady timing, which is why it headed value towers into late 2000. AMD launched the Duron 800 on October 17, 2000. The chip supports MMX and Enhanced 3DNow.

Upper Spitfire clocks with a 35 W envelope suit late-2000 Socket A towers with PC133 memory. That is why the 800 shipped in performance value boxes.

Socket and motherboard compatibility

The 800 fits Socket A late desktops with Spitfire support. It needs a 462-pin board with a 200 MT/s bus and a BIOS that lists Duron 800. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.

Late SDRAM towers are the natural match. Boards listing Duron 800 accept the chip with a 35 W cooler.

Memory, PCIe and cooling

Memory is SDRAM through the board chipset, matched to the board sockets. The CPU has no memory controller. Late boards commonly run PC133 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 35 W cooler.

Upgrade paths

On the same socket, a move to a Duron 850 such as AMD Duron 850 keeps the board for 50 MHz more. A Duron 750 such as AMD Duron 750 drops 50 MHz.

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