Prime 95 v25.9
 CPU 오버 후에 테스트 프로그램으로 많이 쓰이는 프라임 95입니다.
 
New features in Version 25.9 of prime95.exe
1)  Performance increases for the 64-bit version by taking advantage of the
    eight extra SSE2 registers.  The 32-bit version may also be a bit faster
    by taking advantage of the Core 2 architecture.  The FFT code was
    originally optimized for the Pentium 4 where instructions like
    "movapd reg,reg" take 6 clocks and should be avoided, whereas on Core 2
    the same instruction uses just 1 clock cycle and improves scheduling.
    The 32-bit version may be slightly faster or slower on the Pentium 4, but
    not enough to worry about.  Preliminary benchmarks indicate:
 32-bit Pentium 4: between 2% slower and 1% faster
 32-bit Core 2:  between 2% and 6% faster
 64-bit Pentium 4: between 2% and 4% faster
 64-bit Core 2:  between 10% and 13% faster
 64-bit Core i7:  between 7% and 12% faster
 64-bit Phenom:  between 10% and 13% faster
 AMD64:   between 1% slower and 1% faster
2)  Intermediate save files were overhauled.  Trial factoring, P-1, and
    ECM now support multiple save files.  The backup save file uses a .bu
    extension.  While a new save file is being written a .write extension
    is used and renamed when successfully written (thus, briefly there are
    3 save files). NOTE #1: LL save files no longer use an initial letter
    of q and r.  The program will automatically use these obsolete files if
    necessary and delete them when no longer needed.  NOTE #2: ECM and P-1
    save files on k*2^n+1 no longer use file names beginning with d and l.
    The -An command line argument no longer appends an extension to save
    file names.  NOTE #3: The client now supports keeping three save files.
3)  Miscellaneous minor bug fixes.
