Litecoin/Hardware

Litecoin hardware comparison

Notes:

• Any missing information can be assumed stock values or was not available from source.
• The wattage listed is an estimate and may differ from person to person.
• A single number under the Watts heading is likely just the wattage under load. That may not include any extra wattage used by the card while idle (system wattage). Wattage listed as x+y would be the total wattage added to a system.
• Core and Memory speeds are listed in MHz.
• Hash rate is listed in kh/s (kilohash per second).
• Risers are yes or no - used or not used in a rig.
