AMD Athlon64 4000+

1. Introduction

AMD, one of the top CPU manufacturers, was founded back in 1969. Since then, AMD has shipped more than 300 million PC processors worldwide. Especially during the last few years, with the AMD 64-bit architecture, it seems that this is the only manufacturer that can shake the domination of Intel in CPU sales.

In this review, we will be testing the AMD Athlon64 4000+ processor. This is the high-end processor from the AMD Athlon64 family line. Of course, there are even more powerful processors, like the AMD Athlon FX or some new dual core processors. However, as new CPUs are released onto the market, older ones such as the AMD64 4000+ become cheaper. This is why the AMD64 4000+ has become very popular among PC enthusiasts. And after all, the processing power of a dual core processor is not needed by a regular PC user, at least not yet.

So let's have a closer look....

The AMD Athlon64 4000+ is based on the 939 socket, as are all the processors of this product series. The main difference between this processor and all other Athlon64 processors is the L2 cache. As you can see in the table below, only the 4000+ and the 3700+ CPUs have the luxury of a 1MB L2 cache, offering enhanced processing performance with large workloads.

- Features

There are a lot of new features introduced with the AMD 64 series. But other than the larger L2 cache, the 4000+ has nothing more to offer over all the other 64-bit processors.
