Buying A CPU: Performance Vs. Falling Prices
Seen objectively, when choosing a CPU you should make sure it can always supply the computing power you need plus reserves for future tasks. These CPUs are generally available at a reasonable price.
From an economic viewpoint, the fastest and costliest processors only make sense if the extra performance really results in clear time gains for resource-intensive activities, for example, when large scenarios have to be rendered - a procedure that can take minutes or even hours.
Fair warning to all other users: because of their high prices, processors such as the Athlon64 FX 51 and the Pentium 4 Extreme Edition are primarily aimed at enthusiasts who don't need to count pennies. In this article, we reveal which particular processor models are worth considering.
The Platform: Socket A, Socket 478, Socket 754, Socket 940
These days, the general choice of a platform is not simply between AMD and Intel because today's processors call for different sockets.
This issue is resolved most cleanly in Intel systems, since Socket 478 continues to dominate in desktop computing. It's been around since the beginning of 2002 and will continue to form the basis for faster Intel processors in the coming months.
AMD, on the other hand, created two new sockets at once when it launched its 64 bit Athlon: Socket 754 for the Athlon64 and Socket 940 for the Athlon64 FX and the Opteron, the server variant. Also still available is the 462-pin Socket A that accommodates all AthlonXPs up to 3200+.
Thus, the architecture must first be selected. Finally, we'll treat each processor again in detail.
|Socket A||Socket 754||Socket 940||Socket 478|
|Platform||AMD AthlonXP, Duron||AMD Athlon64||AMD Athlon64 FX, Opteron||Intel Pentium 4, Pentium 4 Extreme Edition, Celeron from 1.7 GHz|
|Cost of processor||Low to average||Average to high||High to very high||Low to very high|
|Cost of motherboard||Low to average||Average to high||Average to high||Low to high|
|Performance now||Adequate to good*||Very good||Very good||Adequate - very good*|
|Upgradeability||Low||Good||Good||Good - satisfactory|
|Long-term value||Good to satisfactory||Good||Good||Good|
