Intel Pentium D 940 3.2GHz Dual Core Processor Review
Intel Pentium D 940 3.2GHz Dual Core Processor Review - PCSTATS
Built on Intel's 65 nanometer manufacturing process and with two physical processing cores running at 3.2 GHz each, backed up by 2MB of L2 cache, the socket 775 chip certainly makes quite a splash.

64 Bit Benchmarks: Mini-GZip, DiVX Encoding

Mini-GZIP Source: zlib

The Mini-GZIP benchmark contains both 64-bit benchmark that measures the performance of an AMD64 optimized version of ZLIB. It also contains a 32-bit benchmark implemented with the standard (unmodified) ZLIB. Lower is better.

Mini-GZIP
Processor Seconds Ranking
Intel Pentium D 840 (WinXP 32/32 Bit) 10.47
Intel Pentium D 840 (WinXP 64/32 Bit) 10.47
Intel Pentium D 840 (WinXP 64/64 Bit) 6.25
AMD Athlon64 4000+ (WinXP 32/32 Bit) 8.14
AMD Athlon64 4000+ (WinXP 64/32 Bit) 8.13
AMD Athlon64 4000+ (WinXP 64/64 Bit) 3.69
AMD Athlon64 FX-60 (WinXP 32/32 Bit) 7.64
AMD Athlon64 FX-60 (WinXP 64/32 Bit) 7.62
AMD Athlon64 FX-60 (WinXP 64/64 Bit) 3.31
AMD Athlon64 X2 5000+ (WinXP 32/32 Bit) 7.83
AMD Athlon64 X2 5000+ (WinXP 64/32 Bit) 7.82
AMD Athlon64 X2 5000+ (WinXP 64/64 Bit) 3.47
AMD Athlon64 FX-62 (WinXP 32/32 Bit) 7.28
AMD Athlon64 FX-62 (WinXP 64/32 Bit) 7.28
AMD Athlon64 FX-62 (WinXP 64/64 Bit) 3.12
Intel Pentium D 940 (WinXP 32/32 Bit) 9.28
Intel Pentium D 940 (WinXP 64/32 Bit) 9.28
Intel Pentium D 940 (WinXP 64/64 Bit) 5.83

Again, these test results for Mini-Gzip are with the Intel Pentium D 940 running in 64-bit mode in 64-bit Windows XP. The CPU completes the Mini-GZIP tests over a second faster than the Pentium D 840 model, and at its best comes quite close to 64-bit Athlon64 territory. If anything is clear from these benchmarks it is that running 64 bit software does make a large difference.

DiVX Encoding Source: PCStats

The DivX encoder benchmark contains both a 32-bit and a 64-bit benchmark that measures the performance of raw video encoding of the AMD optimized DivX video encoder version 503. The encoder has been optimized for AMD Athlon 64 and AMD Athlon 64 FX systems (both 32-bit and 64-bit). Lower is better.

AMD Athlon64 X2 5000+ (WinXP 64/64 Bit) 7.031
AMD Athlon64 FX-62 (WinXP 32/32 Bit) 9.156
AMD Athlon64 FX-62 (WinXP 64/32 Bit) 9.205
AMD Athlon64 FX-62 (WinXP 64/64 Bit) 6.347
Intel Pentium D 940 (WinXP 32/32 Bit) 10.462
Intel Pentium D 940 (WinXP 64/32 Bit) 10.461
Intel Pentium D 940 (WinXP 64/64 Bit) 8.85

Even though the DiVX encoder is optimized for 64-bit AMD systems, the 64-bit Intel Pentium D 940 does pretty well for itself. The chip is within a second or two of the high end Athlon64 FX-62 processor.
