Краткое содержание статьи: There is no doubt that the high-performance system we put together is hardly affordable by the majority of you, but you might still be interested in our Dream PC, powered by a chilled Athlon at 1,600 MHz. Tom's Hardware Guide's Power Box doesn't fear any high-end competition.

The Processor Of The Power Box

The Processor Of The Power Box

The first choice I had to make was of course the processor that I would use in the box. Right now there are two CPUs that come to mind, AMD's Athlon processor and Intel's Pentium 4. Those two are rivaling for the best performing PC-processor on the market and so I had to choose one of them.

AMD Athlon

My choice fell onto the Athlon processor for several important reasons. First of all it was clear that the CPU of the Power Box had to run at some super-high clock rate, higher than what you can realize in commercial systems. In other words, the processor of the Power Box had to be 'overclocked'. Intel's Pentium 4 can be overclocked, but the procedure is rather limited. Due to the fact that Pentium 4's clock multiplier is fixed, you need to increase the processor bus clock beyond the specified 100 MHz, which leads to out-of-spec clocks of the Ram-bus, the AGP as well as the PCI-bus. While a reasonably overclocked AGP is just about acceptable, a beyond-spec PCI-bus is paving the road for disaster. Once the PCI-clock goes beyond 39 MHz, the majority of sound, network or SCSI PCI-devices will either run very unreliable or not operate at all.

AMD's Athlon, however, allows you to actually change its clock multiplier as long as you fulfill two conditions. You need a motherboard that supports the adjustment of the multiplier and you have to close the famous L1-bridges on the processor package. Once you have done that, you can overclock the Athlon processor without jeopardizing the reliability of other devices of your PC. The AGP, the memory as well as the PCI-bus remain running 100% within spec and you don't need to worry about problems with your network, SCSI or sound card.

The second reason why I chose Athlon is its performance in today's applications.

The fastest Athlon that is available right now (1200 MHz) is already beating the fastest available Pentium 4 in the majority of benchmarks. Pentium 4 requires software that is specifically optimized to challenge Athlon, while the only widely used application in which Pentium 4 is able to beat Athlon without SSE2-optimizations is Id's Quake 3 Arena.

In summary you could say that Athlon is better suited for overclocking and at beyond-spec clock rates it is able to beat anything that is thrown against it.

История мейнфреймов: от Harvard Mark I до System z10 EC
Верите вы или нет, но были времена, когда компьютеры занимали целые комнаты. Сегодня вы работаете за небольшим персональным компьютером, но когда-то о таком можно было только мечтать. Предлагаем окунуться в историю и познакомиться с самыми знаковыми мейнфреймами за последние десятилетия.

Пятнадцать процессоров Intel x86, вошедших в историю
Компания Intel выпустила за годы существования немало процессоров x86, начиная с эпохи расцвета ПК, но не все из них оставили незабываемый след в истории. В нашей первой статье цикла мы рассмотрим пятнадцать наиболее любопытных и памятных процессоров Intel, от 8086 до Core 2 Duo.
