What the K6-2+ 570ACZ is

The AMD K6-2+ 570ACZ is a 570 MHz single-core desktop processor from September 2000. It runs one K6 Sharptooth core at 570 MHz with no turbo, so 1 core gives 1 thread. Cache is 128 KB of full-speed on-chip L2 with 64 KB of L1 on a 180 nm process. Power is rated at 16 W in a Super Socket 7 CPGA package on a 100 MHz front side bus.

The top K6-2+ clock closes the 128 KB line, which is why the 570ACZ carried premium pricing over the 533ACZ at launch. AMD placed the 570ACZ in September 2000 as the fastest K6-2+ string. The chip supports MMX, 3DNow+ and PowerNow.

Peak Super Socket 7 clocks with a 16 W envelope suit final K6 towers with strong airflow and PC100 memory. The mature 180 nm process keeps the 570 MHz mark within the clip cooler class. That is why the 570ACZ shipped in flagship Super 7 boxes.

Socket and motherboard compatibility

The 570ACZ fits Super Socket 7 flagship desktops with late Sharptooth support. It needs a 321-pin board with a 100 MHz bus and a BIOS that lists K6-2+ 570ACZ. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.

Flagship SDRAM towers are the natural match. Boards listing the 570ACZ accept the chip with a 16 W cooler. Weak early boards with small VRM stages may throttle under the higher current.

Memory, PCIe and cooling

Memory is SDRAM through the board chipset, matched to the board sockets. The CPU has no memory controller. Flagship MVP3 boards commonly run tuned PC100 pairs.

A 100 MHz front side 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 lug clip with a 16 W cooler and steady case air.

Upgrade paths

On the same socket, a K6-III+ 500ACZ such as AMD K6-III+ 500ACZ trades 70 MHz for double cache at 12 W when office software favors cache. A K6-2+ 533ACZ drops 37 MHz at slightly lower power. No faster K6-2+ string exists.

A move to Slot A Athlon needs a new board. The Super Socket 7 page closes the K6 line for planning.
