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. Atthe boot time in general, it has been shown that this is hardly dependent on the clock frequency of the processor, since other components usually delay the system start unnecessarily. While the boot time of the Athlon XP 2000+, Athlon XP 1900+ and Athlon XP 1800+ was only 12.85 seconds on average, the Pentium 4 2.2 GHz was a good 14.2 and the Pentium 4 2.0 GHz only after 15 Ready to use for 69 seconds. However, these results cannot be directly compared, since the mainboard and the onboard components in particular have a major influence on the system start. Since it is difficult to operate a Pentium 4 in a socket A board, we have to live with it for better or for worse. The impact the installation of applications can have on the system start became more than clear after the installation of Sysmark 2001. The boot process was delayed by this application package for a full two seconds. This shows once again how important it is to regularly rid the operating system of unnecessary ballast.
Before we let the ranks of a total of five processors compete against each other in real applications, we would like to take a closer look at the theoretical performance values of the bolides. We used Sandra for this purpose, because here 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.This result is also confirmed when using floating point numbers (floating point data).
Even with the first theoretical results, the Pentium4 and Athlon XP are in a head-to-head race. While the Athlon XP can clearly beat the Pentium 4 in the Dhrystone, an arithmetic test, even the Athlon XP 1800+ is faster than a Pentium 2.2, the Whetstone shows a slightly different picture. At least when the version of the benchmark optimized for SSE2 by an Intel employee is used. Here it is possible for the Pentium4 with 2.0 GHz to take a good 100 points from the fastest Athlon XP. If, on the other hand, the standard Whetstone benchmark is used, the results from the Pentium 4 are in no way convincing. In this case, more than 1000 points separate the Pentium 4 and the Athlon XP. The floating point unit of the processors tested by Whetstone is therefore much more powerful in the Athlon. The Athlon XP wins this test despite its significantly lower clock rate.
Sandra Multimedia Test In Sandra 2002's multimedia test, an algorithm (chaos theory by Mandelbrot) is used, which 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). With the Pentium4 both SSE1 and SSE2 were used.
The results of the previous test were also confirmed in the multimedia test. In terms of integer performance (whole numbers), the Athlon XP is also superior here. This superiority is particularly evident when using the SS1 extension. In this case, even the Athlon XP 1800+ can beat a Pentium 2.2. With the help of the SSE2 extension, this picture shifts only slightly. The Athlon XP 2000+ remains unbeaten and even the Athlon XP 1900+ with a real clock rate of 1.6 GHz can place itself in front of the fastest Pentium 4.
In the multimedia test with floating point data, there is a different result this time. Surprisingly, SSE2 does not accelerate the Pentium 4 in this case. Apparently the optimization leaves a lot to be desired here, although this was also done by Intel. So this time, let's focus on the SSE1 results. As we can see, the Athlon XP 2000+ cuts a very good figure here too. Nevertheless, the Pentium 4 2.2 GHz deserves first place this time. The Pentium 4 2.0 GHz, on the other hand, looks clearly lagging behind. He has to admit defeat to the Athlon XP 1800+.
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 dependent on the platforms, we only want a short oneTake a look.
As we can see, the Pentium 4 can clearly set itself apart from the DDR memory system used in the Athlon XP due to the Rambus platform. We should especially keep this fact in mind in the later course of the test.
