The Bootvis program developed by Microsoft was used to measure the boot speed. This program was actually developed to optimize the boot process and for this purpose analyzes the system start-up down to the smallest detail. Among other things, the boot activity, CPU usage, the hard disk input/output, the driver delay and much more are examined. According to our measurements, the Pentium 4 with 2.4 GHz is almost two seconds faster than its predecessor with 2.2 GHz. Quite a remarkable change when you consider that an Athlon XP with the model number 1800+ can get to the Windows desktop as quickly as the 2000+ model. The start time of the Athlon XP system averaged 12.6 seconds. In comparison, the Pentium 4 was 2.4 GHz after about 12.5 seconds (Pentium 4 2.2 after 14.2 seconds)ready for use, which can be rated as equally fast within the scope of the measurement inaccuracy. However, since the two test platforms differ more than clearly from each other and the mainboard in particular plays an important role in the boot process, the result should never be transferred to every Pentium 4 or Athlon XP system.
Before we let the ranks of five processors compete against each other in real applications, we would like to take a closer look at the theoretical ones Take a closer look at the performance values of the bolides. We used Sandra for this purpose, as both the 3DNow !, SSE1 and the SSE2 expansion of the processors are correctly recognized and used accordingly.
Sandra processor test Sandra 2002 offers two benchmarks that are only intended to determine the performance of the processor. On the one hand, the Dhrystone benchmark is used, which was originally developed by Siemens to measure the performance of the main processor. On the other hand, the performance of the co-processor is determined via the Whetstone benchmark. Both tests are carried out without taking the extended multimedia instruction sets into account. In addition, the SSE2 command extension was used in the Whetstone test.
As we can see, the Pentium4 can significantly increase 2.4 GHz due to the 200 MHz increased clock rate. It can gain a good 10 percent more performance from the 9 percent higher clock rate than its predecessor. In terms of measurement inaccuracy, the latest Pentium 4 is as fast as an Athlon XP 2000+ in this theoretical test. If you consider that the Pentium 4 2.2 GHz had to line up at the end of the test field, a really decent onePerformance.
In the Whestone benchmark, the result is mixed again this time. Without the help of the SSE2 extension, the Athlon XP outclasses the Pentium 4 quite significantly. A good 900 MFlops separate the fastest processors from both camps. If, on the other hand, you run the test with the SSE2 instruction set, the Intel processor increases its performance significantly and can set itself apart from the Athlon with around 600 MFlops. The clock increase by 9 percent, i.e. 200 MHz, leads to a performance increase of a little more than 8 percent. This means that the higher clock rate is converted almost linearly to more power.
Sandra Multimedia Test In Sandra 2002's multimedia test, an algorithm (chaos theory by Mandelbrot) is used, which among other things is also used to generate realistic natural objects such as mountains or clouds. The extended instruction sets of the Pentium 4 or the Athlon XP are also taken into account in this benchmark. Since the implementation of SSE1 is better than that of 3DNow! is, we let the Athlon XP work with its SSE1 unit (i.e. 3DNow Professional). In the Pentium 4, however, both SSE1 and SSE2 were used.
In the multimedia benchmark with integer data, the new Pentium 4 can push itself to the top of the test field. If the weapons are the same, i.e. using the SSE1 command extension for both processors, the Athlon XP is still superior. Simply by using the SSE2 commands, the Pentium 4 executes about 1400 more commands per second, which is the clock ratenot relevant here. Compared to the Pentium 4 2.2 GHz, the performance has increased by 9 percent in an absolutely linear manner.
A first look at the evaluation graphic of the multimedia benchmark with floating point data reveals a poor implementation of the SSE2 extension in this partial test. Nonetheless, the Pentium 4 2.4 GHz can feel like the clear winner here. In this test, too, increasing the clock rate leads to an increase in performance to the same extent.
Sandra memory test Sandra's memory test uses at least 50 percent of the available memory. This benchmark determines the performance of the storage subsystem as well as the caches. Both arithmetic and floating point operations are performed for this purpose. Since this test is very platform-dependent, let's just take a quick look at it.
As we can see, due to the Rambus platform, the Pentium 4 can clearly differ from the DDR memory system used by the Athlon XP Use came, withdraw. We should keep this fact in mind in the later course of the test.
