The story on the Mac IIx's speed is somewhat incomplete.  Here's the info.
direct from Apple's AppleGram:

  The Macintosh IIx is the first CPU from Apple to feature the latest 
  technology from Motorola, a 68030 microprocessor and 68882 math co-
  processor.  This combination improves the performance of most applications
  by an average of 10 to 15% over the Macintosh II, and the performance of
  certain floating-point calculations, such as logarithms and trigonometric
  functions, by up to 200%.

Since someone asked about the super drive, here's the relevant info. on that:

  The Macintosh IIx is the first computer to come equipped with Apple's new
  1.4MB floppy disk drive, the FDHD (Floppy Disk, High Density), making it
  the ideal computer for campuses that want to use Macintosh alongside MS-
  DOS or Apple II-compatible computers.  The FDHD reads and writes to the
  major 3.5" disk formats:  the Macintosh Group Code Recording (GCR) 400K,
  800K, and Modified Frequency Modulation (MFM) 1.44MB formats; the Apple II
  GCR 800K format; and MS-DOS and OS/2 MFM 720K and 1.44MB formats.  Using
  the Apple File Exchange, located on the Macintosh Utilities disk, you can
  now use your Macintosh IIx to access and share files and information
  stored on other types of computers within your workgroup.
