Intel Atom N280 Benchmark with Super_pi

July 24, 2009

I was curious how slow (or fast) the N280 processor is in comparison to other processors so I ran super_pi today. Super_pi is a program that times how long it takes to calculate Pi to 1 million digits. You can read the Ubuntu forums thread to get the program and learn more. (Note the linux program is said to be about 25% faster than the windows version.)

Comparison Benchmarks:
15.8 sec. : Core2 Quad 1600 Mhz, 4096 Cache
38.48 sec. : Athlon 64 2800+ 2ghz
55.03 sec : P4 2.4 Ghz
57.18 sec. : Centrino 1.3 Ghz
58.74 sec. : Athlon 2400+
66 Sec. : Intel P4, 1 GB RAM, 2Ghz
71.4 sec. : Eee PC – 701 4G – Intel Celeron M 900MHz
74.361 sec. : P4 M 1800+ @ 1200 Mhz

77.6 sec : this machine
85.410sec. : P4 1500 @ 1495 Mhz
88.2 sec : Acer Aspire One A110L – Atom N270 @1.6GHz
150 Sec: Pent. M 1.7Ghz 256MB RAM
155 sec. : Pentium III, 700Mhz, 256 MB PC100 RAM
203.8 Sec. :Celeron 566Mhz
209.3 sec. : PowerBook G4 17″ 1Ghz
214 sec : Mac Powerbook 1.33GHz 17″
256.05 Sec. : P2 350Mhz
340.845 Sec : PII 300MHz / 192MB RAM
53 minutes: P1 133MHz laptop with 32MB RAM, and no L2 cache, Win98
46h,56min : 486SX 33Mhz – 20MB RAM-no FPU

My Score:
toshiba-nb200:~/Desktop$ ./super_pi

Version 2.0 of the super_pi for Linux OS
Fortran source program was translated into C program with version 19981204 of
f2c, then generated C source program was optimized manually.
pgcc 3.2-3 with compile option of “-fast -tp px -Mbuiltin -Minline=size:1000 -Mnoframe -Mnobounds -Mcache_align -Mdalign -Mnoreentrant” was used for the
compilation.

I was puzzled to note that there wasn’t much difference in times if I ran super_pi at 1Ghz than when I ran it at 1.66Ghz. Anyone have any idea why?
