That last sentence should be "On the other hand, if your old and creaky code can't be divvied up among a multiplicity of cores, the existence of a far cheaper 64 core, 8 way Nehelem EX machine (or its current equivalent) that's only twice as fast as a single zEC12 core shouldn't much matter."
We could have gotten some meaningful benchmarks. According tho this Register arcticle
When you add it all up, the single-engine performance of a z12 chip is about 25 per cent higher than on the z11 that preceded it. IBM has not released official MIPS ratings (a throwback to the days when IBM actually counted the millions of instructions per second that a machine could process) for the z12 engines, but given that the top-end core in a z11 processor delivered 1,200 MIPS, that puts the z12 core at around 1,600 MIPS.
By the by, we can run a reasonably sized load (800MIPS with our standard package). If the machine in question is larger than that, we can scale to 1600MIPS with our quad Nehalem based package and we have been promised an 8 way Nehalem EX based machine early next year that should take us to the 3200MIPS mark. Anything bigger than that is replicated by a collection of systems.
On the other hand, if your old and creaky code can't be divvied up among a multiplicity of cores, the existence of a far cheaper 64 core, 8 way Nehelem EX machine (or its current equivalent) that's almost as fast as a single zEC12 core doesn't much matter.

The fact is that the world is divided between users of the Macintosh computer and users of MS-DOS compatible computers. I am firmly of the opinion that the Macintosh is Catholic and that DOS is Protestant. Indeed, the Macintosh is counter-reformist and has been influenced by the ratio studiorum of the Jesuits. It is cheerful, friendly, conciliatory; it tells the faithful how they must proceed step by step to reach -- if not the kingdom of Heaven -- the moment in which their document is printed. It is catechistic: The essence of revelation is dealt with via simple formulae and sumptuous icons. Everyone has a right to salvation. DOS is Protestant, or even Calvinistic. It allows free interpretation of scripture, demands difficult personal decisions, imposes a subtle hermeneutics upon the user, and takes for granted the idea that not all can achieve salvation. To make the system work you need to interpret the program yourself: Far away from the baroque community of revelers, the user is closed within the loneliness of his own inner torment. You may object that, with the passage to Windows, the DOS universe has come to resemble more closely the counter-reformist tolerance of the Macintosh. It's true: Windows represents an Anglican-style schism, big ceremonies in the cathedral, but there is always the possibility of a return to DOS to change things in accordance with bizarre decisions: When it comes down to it, you can decide to ordain women and gays if you want to.
The problem with this sort of segregation is that you might have a deaf kid, or a blind kid, or a physically handicapped kid relegated to institutions which do not properly challenge his brain.
A lot of the video websites are optimized for at least 1 Mb, not 768 kps. Short videos are watchable, but buffering is involved. The real problem though, is than many of the streaming sites are supported by video ads--which really screw with the buffers.) (I just updated from 768 kbs. Some services that I would have liked to use were impractical. And I'm single-- not a "household.")
I think it's a great benefit to businesses, educational institutions and governments to be able to expect a certain minimum bandwidth.
A number of 64 bit chips were released with smaller address buses-- the powerpc g5, for instance, had a 42 bit address bus.My Core 2 duo has 36 bit address bus. This is flat, mind you, not banked like PAE.
It seems like every slashdot discussion than mentions HD or Bluray, someone will note that Bluray is obsolete-- streaming, or "gasp" torrenting is so much better, and the discs need to die. But, if I lived out in the boonies, Amazon will mail me a disc, and it'll look gorgeous. If companies follow the advice of slashdot and stop producing blurays, I would not be able to stream films-- because no one will sell me the bandwidth.

In prison, shouldn't the guards be responsible for protecting the inmates from rape? Now, I know the US prison system is supposed to be a third world hellhole, but really, whose fault is that? Not the prisoner's, certainly. Fix it, please...
And really.. WTF?? Anyone can search google and do most web browsing just fine with a 3Mb/s line. OK ..they can't get video. Tough shit. I'm not willing to subsidize their internet access so they can watch Jersey Shore on their PC. YouTube videos are mostly crap. TED is elitist/visionary crap.
Frankly, I don't think you have any idea of what 3 Mb/s is capable of, and what it is not capable of. If you want to volunteer a opinion about bandwidth requirements, I suggest you stick to what you have installed. How fast is your line? Is it fast enough for what you want to do? Do you videoconference, or play games online? If you degrade yourself enough to watch online video, what's the maximum resolution you can stream? What's stopping you from upgrading your line?
Perhaps it's your cable company that's to blame. Why have only one channel featuring crystal clear, pristine video when you can have five featuring an approximation of what was intended?
The deepest images of the universe include the Hubble Ultra-Deep Field (UDF) in the optical (Beckwith et al., 2003), which reaches AB = 29.0 mag in the I band, HST near-IR images of the UDF, which reach AB = 28.5 in the J and H bands (Bouwens et al., 2005a), and the Spitzer Great Observatories Origins Deep Survey (Dickinson, 2004), which reaches AB = 26.6 mag at 3.6 m. Galaxies are detected in these observations at 6
Or how about this:
Hierarchical Assembly: The dark matter mass function of bound objects at very high redshifts can be uniquely measured in two ways with JWST. First, the dynamics of groups of galaxies or sub-galactic fragments can be used to determine the typical masses of halos (Zaritsky and White, 1994). These measurements require observations of emission lines in the rest-frame optical, such as [OII] 3727, [OIII] 5007, and H. These are very difficult to measure from the ground when redshifted into the near-IR. Second, JWST will measure halo masses through the gravitational bending of light. Using this weak-lensing method, ground-based programs have measured the mass within 200–500 kpc of galaxies at redshifts of z 0.1 (McKay et al., 2002) and z 1 (Wilson et al., 2001). Using the superior resolution of HST, these measure- ments are likely to be extended into 30–50 kpc for galaxies at z 1 (e.g., Rhodes et al., 2004; Rhodes, 2004). While there are some hints of variable halo struc- tures for galaxies of different luminosity and total halo mass, the radial penetration of these surveys, and the ability to compare galaxies of different morphologies are 518 J. P. GARDNER ET AL. limited by statistics. We expect that HST will establish the statistical mass functions for spiral and elliptical galaxies at z 1, but not much beyond that, because of its limited sensitivity and sampling at > 1.6 m. JWST will extend the equivalent measurements of galaxies to z 2.5 and thus determine the development of the dark matter halos during the peak growth of galaxies and star formation. JWST will require near-IR imaging with high spatial resolution and sensitivity to achieve this greater depth. Background galaxies with a size comparable to the resolution of JWST will be measured at 20 . The same near-IR sensitivity and resolution will also make JWST superior to those of ground-based facilities and HST for the study of dark matter structures on larger scales, e.g., 1–10 arcmin or 2–20 Mpc (co-moving) at z 3. These volumes measure the clustering of dark matter on cluster or even supercluster scales, and would extend the study of the mass function into the linear regime. The goal of these observations would be to verify the growth of structure between z 1000 (the CMB large-scale structure) and z 2.5, i.e., during the period that dark matter dominated the cosmological expansion of the universe prior to the beginning of dark energy dominance at z 1.
It's not all about the redshift, the paper also describes potentially useful observations in the IR-- planet formation, star formation, etc. And,of course, optical telescopes have a hard time resolving what's behind dust clouds-- ir telescopes can see beyond them

They fail against mid-range x86 Xeon rackmount server in every non-I/O benchmark.
But what if you need I/O?
Your 177730 MIPS figure is mirrored by this wikipedia page. Using the same criteria, 30 MIPS is around a 33 MHz 80486,or perhaps even a 68040.
Unless you have an irrational suspicion of IBM, it's fairly reasonable to assume that a mainframe MIP is not a Dhrystone MIP.
