UltraSparc was not that impressive in SPECINT2000 benchmarks. The only compatative systems were Fujitsu UltraSparc compatible CPUs

Low level servers like V240 are less then half on SPECINT performance:

But please note that SPECINT is extremly CPU intensive. In real life situation memory not CPU will be the bottleneck for most applications.

Also the quality of the compiler is important. Sun Studio 11 probably is one of the best C compliers on the market and is definitely the best for UltraSparc, so using it for compiling open source applications instead of GCC might make the differences significantly less severe.

Old News ;-)

[Nov 9, 2005] Fujitsu UltraSparc compatible CPUs are competitive with Opteron on SPECint2000/SPECfp2000. They managed to get more then 1200 on SPECint_base2000 for 1.8GHz CPU  and over 1400 for 2.16 GHz CPU.  That's slightly faster then Opteron 252 (SPECint_base2000 1382).  In 1T  transaction procession IBM still have a lead.

2.16 GHz CPU.

SPECint2000 = 1594     
SPECint_base2000 = 1456
SPECfp2000 = 2139     
SPECfp_base2000 = 1808  

1.8HHz CPU

SPECint2000 = 1344     
SPECint_base2000 = 1256 
SPECfp2000 = 1803     
SPECfp_base2000 = 1510 

Sun 20z (Opteron 252)       

SPECint2000 = 1521     
SPECint_base2000 = 1382  
SPECfp2000 = 2036     
SPECfp_base2000 = 1852 

All Published SPEC CINT2000 Results. It looks like Opteron 250 based system are on average 2 times faster then fastest UltraSparc CPU (1.6 GHz) on integer calculations.   1.6 GHz CPU get a respectable 743 (approximately twice less then top Opteron CPU). The best Opteron system has 1569. BTW  Ultra 10 333MHz, which along with Ultra-5 was the most popular Sun workstation in late 90th, has CINT2000 rating of just 133.

[Oct 17, 2005] Overview of Sun's new UltraSPARC IV+ 64-bit processor

Sun's new UltraSPARC IV+ 64-bit processor is the fifth generation in our UltraSPARC processor family. It comes with significantly enhanced cores, 2 MB on-chip L2 cache, and an off-chip 32 MB L3 cache. The 1.5 GHz processor follows Sun's Throughput Computing vision while continuing the tradition of binary code compatibility—and uses the latest 90 nanometer process technology.

... ... ...

The UltraSPARC IV+ processor uses Chip Multithreaded Technology that supports two simultaneous threads as a result of two independent cores. Operating at 1.5 GHz, the UltraSPARC IV+ offers up to five times the performance of UltraSPARC III servers and up to double increased performance over UltraSPARC IV servers in the same footprint, with no increase in power and cooling requirements.

[Oct 17, 2005] New hopes from Sun's idea factory - page 2 CNET News.com

Sparc servers remain Sun's most important business, and boosting Sparc sales is probably the single easiest way for the company to restore financial health, even though market researcher IDC forecasts the $19.1 billion market for Unix server servers will shrink by $200 million during the next four years, while Linux and Windows sales continue to grow.

"No matter how Galaxy takes off in the marketplace...it's going to be off a comparatively small base," Schwartz said. "We're in the billions of dollars of opportunity in the Solaris-Sparc marketplace." Sparc server sales also tend to tow along other business, such as data storage and customer services, Sanford C. Bernstein analyst Toni Sacconaghi said.

Here's the Sparc lineup today: UltraSparc IV, released in 2004, and its new IV+ sequel released this month. Both feature a dual-core design, which puts two processing engines on the same slice of silicon.

Next in the Sparc rejuvenation plan comes Niagara, an eight-core processor that can execute 32 simultaneous instruction sequences called threads while consuming only 56 watts of power--less than half of an Intel Xeon, which can handle handle four threads.

There are indications that Sun has already piqued some customer interest. Internet auction giant eBay is among the customers trying the machines, sources familiar with the testing program said. eBay declined to comment.

Not surprisingly, competitors are quick to downplay Niagara. "For Sun's declining installed base, it's going to be a great product," Pat Gelsinger, general manager of Intel's Digital Enterprise Group, said.

Maybe so, but it's a customer base Sun certainly needs to keep happy, and those high-end customers can be leery of x86 machines. "What we need is something that is solid or stable," said Carsten Larsen, general manager of commercial development for Australian utility provider ActewAGL.

And Sun has other plans. Next up is the "Advanced Product Line" partnership to sell servers with Fujitsu's Sparc64 VI "Olympus" processor beginning in late 2006.

Then comes Niagara II, built with a more advanced manufacturing process. Its features include hardware acceleration of at least seven cryptography algorithms, the ability to cooperate with Solaris to classify network traffic and send it to the appropriate processor core, and a built-in 10 gigabit-per-second Ethernet interface, said David Yen, executive vice president of Sun's Sparc group. In addition, it will be possible to make systems with multiple Niagara II chips.

Sun's public chip plan extends as far as "Rock." Where Niagara is geared for network-oriented tasks such as application servers or Web site hosting, the Rock chip family due in 2008 is designed for back-end tasks such as databases, where a single thread must execute as fast as possible.

Rock also will accelerate Java programs, facilitating the "garbage collection" process by which unused memory is freed for use, Yen said. Initial hardware design for both Niagara II and Rock will probably be completed in the first half of 2006, Yen said.

Rock, Niagara and Galaxy aren't a sure bet, of course. But many customers still would double down on Sun.

"Sun has been around for a long time," ActewAGL's Larsen said. "We're confident they're going to be around for some time to come."
