Sorry, I couldn't help myself. I finally finished that game 3 years after it came out and 2 hardware upgrades later. Still brought my computer to a crawl, especially near the end

I doubt its even remotely as fast as its made out to be. And since its not compatible with windows, there will never be any benchmarks against an overclocked  5.2GHz i7 to prove it. At least not with an non server application.

 

Alls we know is that its 5.2GHz and a quad core with a somewhat small amount of cache. What kind of memory does it use? Security? Transistors per core? Cache latency?

 

I can overclock a Pentium 4 to 5.2GHz and sell it for a million$ but that doesnt mean its faster than an i7

This is a mainframe processor designed to be used in (very expensive) mainframe systems. Mainframes are generally used when you have tons and tons of data; they specalise in handling bulk data (as opposed to a supercomputer, which specalises in raw computational power).

The z196 is designed around the workload that you would have on a mainframe, not on a desktop; specifically handling bulk data. For starters, the processor has four levels of cache (128KB L1 Data, 1.5MB L2, 24MB Shared L3, and up to a 196MB L4 cache implemented in an MCM).

The z196's onboard DDR3 memory controller also suppirts a form of RAID for RAM called RAIM which stripes RAM for added fault protection. And it uses a 128-bit data bus.

For what it's designed for (processing potentially tens or hundreds of terabytes of data an hour), this chip would run circles around the x86.

...the mobo this pluggs into.  We all get to see the hot desktop/workstation boards, but nothing that these line of procs plug into, unless you manage a server of this magnatude.

Too true, unfortunately.  The average geek might soil his or her pants at the mere thought of being able to own one.
