This sedum was sold as Sedum 'Fine Gold Leaf'. I have it growing about 2 feet away from Sedum 'Gold Digger'. I thought when I got them they looked like the same plant. They still look like the same plant to me.
The name of S. 'Fine Gold Leaf' photos on the web show it as looking identical to Sedum hispanicum 'Aureum' and Sedum japonicum 'Tokyo Sun', which also look to be the same plant, just different names.
