Conclusion

   We have tested the Pentium 4 2.8 GHz with the D850EMV2 motherboard from Intel. We ran many benchmarks to compare the Pentium 4 2.8 GHz with other Pentium 4 processors (including P4 2.66GHz FSB 533MHz) and its eternal AMD rival: the Athlon XP 2200+. To run our various tests we used the latest bios available with 256 MB of memory and with a Hercules 3D Prophet II Ultra (based on the GeForce 2 Ultra GPU) graphic board. The hard disks used were a Maxtor UDMA 100 7200 RPM 30 GB and a IBM UDMA 100 - 7200RPM 40 GB. You can read the complete PC Setup below.

Ziff Davis CPU Mark 99 is a rather old benchmarking tool that doesn't take advantage of the new instructions brought by the Pentium 4. In this test the Pentium 4 2.8GHz teamed up with Rambus 1066 memory gets kudos and beats all other processors, including the Athlon XP 2200+. The Pentium 4 2.8GHz is 8% faster than the Pentium 4 2.66GHz, 13% faster than the Athlon XP 2200+ & Pentium 4 2.53GHz and  44% faster than the Pentium 4 2.0aGHz!

CPU MathMark 3.0 trains the processor to perform some basic and complex mathematic operations (like 9^1500, calculating iterations of Pi, etc.) Once those tests are completed it reports the time it takes for the CPU to achieve such operations in seconds. Shortest is the bar in this graphic, faster is the CPU.

The Athlon XP 2200+ beats every Intel Pentium 4 processors, including the 2.8GHz, thanks to AMD's architecture optimized for mathematic operations. The Intel Pentium 4 2.8 GHz with PC1066 memory arrives second. The Athlon 2200+ is 13% faster than the Pentium 4 2.8GHz. Nonetheless the Pentium 4 2.8Ghz is 5% faster than the Pentium 4 2.66GHz while being 34% faster than the Pentium 4 2.0a GHz.

SiSoft Sandra 2002 is a synthetic benchmark that performs real basic test measuring Whetstone & Dhrystone values of a CPU. This benchmark program doesn't reflect at all the potential of a Pentium 4, but since it's a widely used performance measuring utility I can't skip it. The Pentium 4 2.8GHz gets the best results (what a surprise :)): its MFLOPS score is 40% better than the one of an AMD Athlon XP 2200+. In this test the Pentium 4 2.8GHz MIPS score is 1% faster than the Pentium 4 2.66GHz.

MFLOPS: The Whetstone benchmark is widely used in the computer industry as a measure of performance. Floating-point arithmetic is most significant in scientific, engineering, statistical and computer-aided design (CAD) programs. It is also a small component in spreadsheet, paint and drawing programs. Word processing programs typically do no floating-point computations at all. The Whetstone does a lot of floating-point arithmetic, some memory access, and a little integer arithmetic.

MIPS: The Dhrystone benchmark is widely used in the computer industry as a measure of performance. Dhrystone is a synthetic benchmark, designed to contain a representative sample of operations normally performed by applications. They don't calculate a result of any kind, but they do perform the sort of complicated sequences of instructions that real applications use. The Dhrystone result is determined by measuring the time it takes to perform these sequences of instructions. Simple integer arithmetic, logic decisions, and memory accesses are the dominant CPU activities in most Windows programs. The Dhrystone benchmark makes intensive use of these areas.

PCMark 2002 is MadOnion's brand new benchmark. PCMark2002 consists of a series of tests that represent common tasks in home and office programs. The Pentium 4 2.8GHz logically arrives on top of the race, outperforming by 29% the Pentium 4 2.2Ghz and the Athlon XP 2200+ since both processor get almost the same score. In this test, the Pentium 4 2.8GHz is 5% faster than the Pentium 4 2.66GHz.
