2x512 MB PC3200 DIMM DDR SDRAM Registered Corsair (2-2-2-5).3.4 GHz Intel Pentium 4 (Northwood), Socket 478.3.4E GHz Intel Pentium 4 (Prescott), Socket 478.You can just evaluate their performance in comparison with the numerous K8 family. But we are not going to analyze their results, because this has been already done before. We have also added to the diagrams the results of Intel Pentium 4 processors at 3.4 GHz on Prescott and Northwood cores based on i875 platform with dual channel DDR400 memory. Note that this article uses the data obtained according to our "old" method. Dual channel operations with regular (non-registered) DDR400 memory.We have already analyzed Socket 939 products before, let's just briefly mention their features: There is one more formal difference – speed of the external HT-link, so some tests may experience the effect of this parameter. These six processors will help us evaluate application requirements to such CPU characteristics as L2 cache capacity, dual channel mode, and registered memory. The results matched perfectly, so there is no point in publishing them. We have also tried to make 3400+ out of 3800+ by installing only one memory module. So, we have selected 2.4 GHz AMD64 processors for all modern sockets for this article. For example, Athlon 64 FX-51 and Opteron 148, Athlon 64 FX-53 and Athlon 64 4000+. Still more confusion is due to the fact that there are not only different models with the same rating, but vice versa – actually the identical processors may have different names. Fortunately, the figure showing L2 cache capacity can be easily found in the marked code. For example there is Athlon 64 3400+ in the following modification: 2.2 GHz/1 MB L2.
It's interesting to note that the rating, though evaluating performance, still does not provide exact information on processor parameters. The table of ratings below is not complete, however it features all state-of-the-art models. For example, a recent AMD Sempron 3100+ is marked SDA3100AIP3AX. This table tends to grow with the release of new models. Unfortunately, the latest processor announces set the fur flying on the orderly rows of AMD products and so (once again) we remind you of the expansion of OPN numbers (by the example of Athlon 64 3200+ coded ADA3200AEP5AP). Especially if you take into account that the prices of models equal in frequency may differ more than twofold.Ĭonsidering the increasing popularity of this platform, we thought it a good idea to compare all possible AMD64 processors at 2.4 GHz and try to figure out what effect the above mentioned chip parameters have on various applications.
However these days AMD manufactures a lot of models, which differ not only by their frequency, but by the L2 cache capacity and memory controller features, so it's rather difficult to choose a processor by these parameters. Effect of this parameter on the overall performance is obvious. They differ from their predecessors primarily by the increased frequency. New models for this platform have been recently announced – Athlon 64 4000+ and Athlon 64 FX-55.
Almost half of the year has passed since the announcement of the AMD platform with evolutionary Socket 939.
