Socket AM2+
Athlon 64 x2 are dual-core microprocessors best suited for running multiple applications on one computer. "X2" part in name is easy to explain - these processors incorporate two Athlon 64 cores on one die, hence it's an Athlon 64 x2. Having two-cores on one die comes at a price, though:
  • X2 processors have much bigger die size - 218 mm2 for 0.09 micron processors with 1 MB L2 cache. For comparison, Athlon 64 with 1 MB L2 cache has almost two times smaller die size (112.9 mm2).
  • Power consumption of two-core CPU is higher. For example, socket AM2 Athlon 64 X2 3800+ has Thermal Design Power 89 Watt, which is 27 Watt more than TDP of Athlon 64 3800+.

Athlon 64 X2 microprocessors have model numbers that show relative performance of the CPU. Because model numbers are calculated based on average of wide range of benchmarks, actual processor performance may differ for Athlon 64 and Athlon 64 X2 processors that have the same model number:

  • X2 microprocessors will be faster than single-core Athlon 64 when running multiple applications.
  • Single-core CPUs may be faster when running single-threaded programs. This happens because dual-core processors have lower frequency of each core, and, if the application doesn't utilize second core at all, the X2 CPU performs as single-core Athlon 64 running at lower frequency.

For averaged performance of Athlon 64 X2 processors please see AMD Athlon 64 X2 multi-threading and single-threading performance pages.

AMD Athlon 64 X2 3600+ - ADO3600IAA5DD (ADO3600DDBOX)
1.9 GHz
Dual-core
1 MB L2 cache
Socket AM2
The ADA3800DAA5BV CPU was released two months after introduction of Athlon 64 X2 family. This processor has two cores on one die, each running at 2 GHz frequency. Effectively, this processor is like two socket 939 Athlon 64 3200+ CPUs in one package. While rated as 3800 MHz processor, performance of the ADA3800DAA5BV may vary depending of the type and number of applications it runs. When running one single-threaded application the 3800+ may perform close to Athlon 3200+. The processor performs much better when running multi-threaded or multiple applications. For these applications the ADA3800DAA5BV is always faster than single-core 3800+, and in some cases it may be 20% or more faster than the Athlon 64 3800+.

AMD Athlon 64 X2 3800+ - ADA3800IAA5CU (ADA3800CUBOX)
ADA3800IAA5CU has the same basic features as ADA3800DAA5BV, but it requires new socket AM2. Socket AM2 is a socket with 940 pin-holes, and it's not compatible with socket 939 or older 940. Socket AM2 added support for DDR2 memory, which at this time (Nov 2006) may be as twice as fast as DDR1 memory used by socket 939 processors. Faster access to memory results in slightly faster CPU performance. On average, this socket AM2 3800+ is a few percent faster than socket 939 3800+, even though both processors have the same rating. For some memory-intensive applications the difference in speed may be as high as 15-20%.

AMD Athlon 64 X2 4200+ - ADD4200IAA5DO / ADD4200IAA5DOE
ADD4200IAA5DO is the fastest socket AM2 dual-core processor with Thermal Design Power 35 Watt. Because it's an embedded microprocessor, it may be difficult to find one for sale for acceptable price. Other low power options for socket AM motherboards are Athlon 64 X2 3800+ with 35 Watt TDP (somewhat slower, but easier to find), Athlon 64 X2 BE-2400 / 4450e / BE-2450 / 4850e / 5050e (faster, easy to find, but has higher TDP), and embedded Athlon 64 X2 3400+ with 22 Watt TDP (lower power consumption, but slower and difficult to find).

Currently (Nov 2006) the dual-core Athlon 5200+ is the fastest officially released member of the Athlon 64 X2 family, and the second fastest processor from AMD desktop microprocessors after the Athlon 64 FX-62. The 5200+ was quitely introduced in September of 2006. At that time the 5200+ was listed on on AMD site with the part number ADO5200IAA6CS. What's interesting about it is that the third letter 'O', that usually describes CPU's thermal design power (TDP), was previously used only for processors with 65 Watt TDP. In contradiction to this the ADO5200IAA6CS had TDP 89 Watt. Recently, in November of 2006, the part number ADO5200IAA6CS was replaced on AMD site with ADA5200IAA6CS. According to AMD's site, both processors have exactly the same characteristics.
AMD Athlon 64 X2 6400+ is the fastest dual-core processor for socket AM2. This processor is the best socket AM2 upgrade for people who mostly play games. For 3D rendering, Video encoding and similar applications the Phenom 4X microprocessors could be a better upgrade option. Although at this time (March 2008) the fastest Phenom 4X runs only at 2.5 GHz, it has much better performance in multi-threaded applications than the Athlon 64 X2 6400+ due to improved micro-architecture, and primarily due to quad-core design.

The smallest Athlon 64 X2 cpu is 3600+
I think there is only one difference between 3600+ and 3800+ that 3600+ has only 2x256KB L2 cache. Frequency is same (2GHz).

I don't see any mention of the AMD Tri-cores nor any special mention of the X2 AM2 black edition 5000+ with the unlocked multiplier...did I miss some thing or a mention of these?

Response: ADO5000IAA5DS is a Black edition 5000+ (I'll add "Black Edition" to the title later this week). Phenom X3 are here - http://www
