The processor’s performance can’t be decided by checking one factor. It depends on several factors like CPU speed, dual or quad core, bandwidth, front side bus speed, level 2 cache, and compatibility.
- CPU Speed: CPU speed tells the rate at which your computer can run programs.
- Quad core: If you want to run lot of applications then quad core processor is better one, or if you are planning to buy for gaming purpose then dual core is adequate.
- Bandwidth: Bandwidth tells the amount of data our PC can run in one instruction. There are 32 bit and 64 bit processors available.
- Front Side Bus Speed: Front Side Bus, it relates the amount of data between CPU and other parts.
- L2 cache: If the size of the level 2 cache is more then that processor is considered to be better one. Your desired CPU has to be compatible with the motherboard chip set.
Advanced Micro Devices and Intel Corporation are working to create low-power high-performance microprocessors. Intel processors are high priced when compared with AMD processors but it can perform certain tasks that AMD can’t. Intel is targeting on high level enterprise markets, while AMD is on home users in mind.
Latest AMD Athlon 64FX-60 vs Intel Core i7:
The AMD Athlon 64FX-60 is cheaper and better at running every day applications than the Intel Core i7 but is slightly slower than FX-57 when running games. Compatability is guaranteed for the FX but not with Core i7. All AMD Athlon processors move ahead of Intel’s Pentium EE 955 in the primary 3DMark05 graphics test, but Intel’s 955 takes a commanding lead in the CPU test.
The FX-60 leads the pack in the multiprocessor-capable Windows Media Encoder 9 test, but when it comes to brute-force single-threaded encoding, the 2.8GHz Athlon 64 FX-57 leaves every other processor far behind.
Now, lets compare between two server processors: AMD Opteron and Intel Xeon.
- It has been the faster processor, when it comes to floating point operations.
- HyperTransport provides for an interconnection between processors and core logic. This point-to-point interconnection scales much better than bus interfaces.
- Power consumption is acceptable even when under high load.
- Socket 940 is the backbone for all Opteron models that have been released. You can usually upgrade to one of the dual core models.
- Each processor will have its own memory controller.
- No Fully Buffered-DIMM memory is required. Registered Double Data Rate (DDR400) memory is enough.
- Quad-core Opteron processors will require a Socket F platform.
- The Front Side Bus is the interface and also a cause for a potential bottleneck between the processor(s) and the chipset northbridge. The 5000 chipset widens this obstacle by implementing separate Front Side Busser per processor (DIB).
- The Dual core Xeon Paxville DP has tremendously high power requirements.
- Dual Core Xeon Dempsey 5000 has moderately high power requirements.
- Less flexible platform design: A Xeon Nocona or Irwindale (socket 604) can be upgraded only with a dual core Xeon Paxville DP. If you need a Xeon 5000 (Dempsey) or Xeon 5100 (Woodcrest) you may require the 5000 chipset platform for socket 771 (Bensley).
- Quad channel DDR2 memory controller would offer more bandwidth, but then requires FB-DIM modules.
- Intel’s chipset and FB-DIMM components require more energy than the equivalent Opteron processors.
- Quad core Intel Xeons are technically feasible for socket 771.
The above given details will help you to understand which processor is better based on your requirements. Ultimately it is you to decide based on your computer usage and requirements.
