A interesting article about the upcoming SPARC T4 is available from IDG but only with an subscription. The article is also available in text form on a Danish Oracle blog.
Excerpts from the article:
"The new T4 processor, running at 3GHz or more, has features that will also allow T4-based systems to take on some workloads that today are going to Intel Xeon processors, which today perform faster on single-thread workloads than do the T3- series of SPARC processors."
"At the Hot Chips 2011 conference, an IEEE technical conference held at Stanford University from August 17-19, 2011, Oracle systems engineers described the top features of the new T4 processors, including a 16-stage integer instruction pipeline and enhanced cryptographic performance. Among the business benefits associated with the new design will be: double the amount of per-thread throughput performance, compared to T3 – and a range of 2 to 7 times more single-thread performance for business workloads than T3 processors. Given the binary-compatibility of T3 and T4, this means that the same Oracle Solaris applications that have been running on T3 will see considerable speedup on T4, without recompilation."
