Arby's version weighs in at 6.4 ounces and is a 52% blend of American Wagyu and 48% ground beef that is cooked "sous vide style" to create a juicy and tender burger.

"Instead of focusing on making billions of mediocre burgers, we're taking a stance on high-quality meat that deserves to be cooked properly," Patrick Schwing, Arby's chief marketing officer, said in a statement.

The Wagyu Steakhouse Burger is served with American cheese, shredded lettuce, tomato, pickles, red onion and a "special burger sauce" on a toasted brioche bun.

Arby's claims its 50% bigger than McDonald's Quarter Pounder, which about four years ago switched from frozen beef to fresh beef.

Arby's is owned by Inspire Brands, the country's second largest restaurant company that comprises of 32,000 locations across its brands, including Arby's, Baskin-Robbins, Buffalo Wild Wings, Jimmy John's, Dunkin' and Sonic.

The privately held company recently announced Arby's sales at stores open at least a year grew more than 5% in the first quarter, closely mirroring its rivals like McDonald's and Wendy's.

Inspire said it "achieved record performance results" last year, with global sales across all of its brands exceeding $30 billion.
