Intel E6420 vs. AMD 5600+ Author:  Michael Lynch Date:  2007.07.23 Topic:  Processors Provider:  AMD Manufacturer:  AMD

Processor Specifications:

            As we can see on the chart below the AMD Athlon 64 x2 Dual Core Processor is made to run at a speed of 2.8 GHz (2800 MHz)- this is acquired by a bus speed of 200 and a CPU multiplier of 14.  The core voltage is defaulted between 1.3 and 1.35, which can be changed if interested in overclocking.  Another great thing to keep in mind while overclocking is that the maximum temperature of the CPU is rated between 55 – 70 degrees Celsius. This is good to know so you can keep your processor cool and not worry about frying it.  The CMOS Technology as it is called my AMD is 90nm.  The amount of L2 cache is 2MBs, one per core, and the amout of L1 cache is 128kbs.

            As for the Intel’s Core 2 Duo E6420, it is rated at 2.13 GHz (2133 MHz)- this speed is obtained by a bus speed of 266 and a CPU multiplier of 8.  The core voltage on the Intel is also default within 1.3 and 1.35 volts.  The manufacturing technology (CMOS Tech) is 65 nm.  It has 4MBs of L2 cache and 64kbs of L1 cache.

            There are many differences between the two different processors.  The main difference being in speed: the AMD is rated at 2.8 while the Intel is 2.13.  Another big difference is that the CMOS Technology on the AMD is 90nm while it is 65nm on the Intel; this figure is the size and spacing of the transistors on the chip which is measured in microns (1micron = 1 / 1,000,000 meters).  You should be aware that the AMD Athlon's memory controller is built into the CPU while the Core 2 Duo is not. The E6420 also has the advantage of having twice the amount of L2 cache of the 5600+ and recent tests all show that cache plays a huge role in benchmarks.
