As I see it the GB numbers are powers of 1000 rounded down:

2492 * 16 * 63 * 512 / 1000 ^ 3 = 1.286111232

4092 * 16 * 63 * 512 / 1000 ^ 3 = 2.111864832

4994 * 16 * 63 * 512 / 1000 ^ 3 = 2.577383424

Using GiB you get different numbers if you look past the first element in the table:

2492 * 16 * 63 * 512 / 1024 ^ 3 = 1.197784423828125

4092 * 16 * 63 * 512 / 1024 ^ 3 = 1.966827392578125

4994 * 16* 63 * 512 / 1024 ^ 3 = 2.4003753662109375

So I stand by my point, they have always used SI units. It's only ram (and software) that used incorrect definitions of k, M, G and T.
