8/28/2023 0 Comments Performance benchmark computerThe Z80 CPU is an 8 bit CPU, but it does have internal 16 bit registers. This clock speed is much greater than the Commodore 64 one. This computer offers 128K RAM of memory, and is powered by a Z80 CPU 3,54 MHz. The +2 keyboard is excellent, despite the unusual position of the DELETE key. That helped me to type the benchmark programs with no problem. Being a Commodore 64 user, the Spectrum 128 keyboard is more confortable to me than the original 48K one. I had a 48K Spectrum but I sold it some time ago (and I do regret it). I choose this computer because is the only Spectrum I own at the moment. The Sinclair ZX Spectrum 128 +2 is a Spectrum version made by Amstrad in 1986. For our benchmark tests, the 2 MHz fast mode available on C128 80 columns mode will be used, so that programs will not need to be accomodated for the FAST/SLOW modes switching. This way, screen will be blanked only during program execution. So, if you only have RF connection and you are not able to have the VDC video output, you can test those programs by adding a BASIC line with the FAST command at the very beginning of each program, and by adding another BASIC line with the command SLOW at the end of the programs. ![]() Still, as those benchmarks programs don’t use screen, blanking the screen may be tolerated. 2 MHz can be activated on 40 columns mode actually, but no image will be shown. So, when on C128 40 columns mode, the CPU must be forced to 1 MHz operation. Unfortunately, the VIC-II chip is not able to work properly when the CPU is at 2 MHz. It also offers bitmap graphics, with a resolution of 640 x 200. This computer has two video chips: a variation of the C64 VIC-II chip, and a VDC, for 80 columns text. It has 128K RAM and a 1Mhz/2MHz 8502 CPU, very similar to a 6510. The Commodore 128 may be regarded as a powered-up version of the Commodore 64, from 1985. They enjoy fast memory access and for this reason they are “memory oriented” CPUs. 65xx family CPUs have a small instruction set and they have few registers. Commodore 64 BASIC is actually a Microsoft BASIC implementation. ![]() 64K RAM of memory, only 38911 RAM bytes available for BASIC programming. It has a 6510 CPU running at only 0,98 MHz on PAL systems. The Commodore 64 is a computer from 1982 we definetely know about. Two 128 K machines, and three 64K ones:Īll these tests have been performed on PAL machines. Still, in order not to make tests too long, I decided to only test five computers. I don’t have a big collection, so I couldn’t make a perfect choice. Different home computers models may have different BASIC dialects, but very simple programs will run on all of them.Īfter reading this web page, I decided to test these programs on some home computers I own. ![]() Different processors, different memory management schemes, different Operating Systems… all of this makes it extremely difficult to do benchmarks on these systems.īut, most of these systems do have one thing in common: a BASIC interpreter in ROM, available at start-up. This is rather difficult for 8 bit home computers, as each of them usually has a unique architecture. All you have to do is to click on “Start benchmark test” and wait for the result.When reading some web content on home computers comparisons, I started asking myself if there is a way of evaluating performances on a fair bases. These are the best tools to overclock PC plus you can also benchmark CPU and GPU with them. ![]() You can choose and download any of the following on your computer Many popular computer benchmarking tools are free and support windows 10 PC. If the windows performance monitor doesn’t prove much useful to you then you have the option of a wide variety of tools. It uses red, amber, or green lights to indicate the severity of the issues and provides details on the current status of the system. Resource Overview: This section will give you an overview of the major parts of your system including the CPU, Disk, Memory, and Network. Informational: Provides some more information about the processor, network cards, etc,īasic System Checks: This shows you the information of the OS, Disks, Security Center related information, System Services, Hardware, and Drivers. It provides related links to more information about the situation and how to solve it. Warning: This section comes up if there are any warnings of issues the computer is facing. This report also includes suggestions for ways to maximize computer performance and streamline system operation. Here you’ll find the reports consisting of the following subsections: Once the scan is finished click on the Diagnostic Results tab.
