Guide to AMD® Desktop Processors for Personal Computers

Processor Micro-Architecture
Details
AMD Family 10h/K10/Stars AMD Family 10h (or K10 or "Stars") comprises the 65 nanometre (65nm) "Barcelona" and 45nm "Shanghai" families of server processors, and the 65nm and 45nm "Stars" families of desktop processors. The new 45nm versions (Phenom II) are substantially better than the previous 65nm releases and are close to competing Intel 45nm "Penryn" models in performance and efficiency. However, they remain far short of the newest Intel "Nehalem" micro-architecture. Nonetheless, AMD is making technological progress in a very difficult economy and marketing environment.

AMD's newest technology has cut processor power consumption by more than 30% in some scenarios. AMD has also aggressively reduced 45nm prices to better compete in the quad-core CPU market.
AMD 64/K8™ AMD64/K8 is Advanced Micro Devices' 2003 vintage micro-architecture. Released in 2003 with an integrated memory controller, K8 proved to be an excellent 64-bit and 32-bit solution at the time. Since, Intel Corporation has aggressively responded with Intel Core processors and have surpassed AMD.

K8 models include the Athlon 64, Athlon 64 X2, Athlon 64 FX/Quad FX, Athlon X2, and Sempron families. Ninety nanometer (90nm) processors have been discontinued and most sixty-five nanometer (65nm) K8 consumer and business desktop processors are soon to follow. A handful of models will remain available through the end of 2009 and into early 2010. Laptop models will continue to be offered through 2010.
AMD Black Edition Processors AMD Black Edition models are offered from both micro-architectures listed above. AMD Black Edition processors feature an unlocked core multiplier allowing easy custom configuration of processor performance in like manner to Intel Core i7 Extreme Edition and Core 2 Extreme models but at a fraction of the price. AMD Black Edition models such as Athlon 64 X2 5400+ BE and Phenom II X4 940 BE and 955 BE are ideal for enthusiasts who want to get the most out of their computing experience.

Quad-Core Processors
Details
Phenom II X4 Socket AM3/AM2+

AMD Phenom II X4 processors are competitive alternatives to mainstream Intel Core 2 Quad products. Models listed at right are excellent performers.

Socket AM3 models are compatible with DDR3 RAM.

The Phenom II X4 series represents a major improvement to the AMD lineup. Phenom II processors are competitive to the Intel Q8200 through Q9300 and are in some respects better.

The Black Edition models can be substantially overclocked by custom builders for greater performance. They are offered at a reasonable price point considering their capabilities.

Except as noted, all models have 512KB L2 Cache per core plus 6MB shared L3 Cache for a total of 8MB on-die cache RAM. Models such as the 810 and 805 with a total of 6 MB Cache RAM have partially disabled L3 Cache memory. However, this does not impact reliability as the defect is permanently isolated during manufacture.

Phenom X4 9000 Socket AM2+

Phenom X4 9000 processors are suitable quad-core processors when priced below all Intel Core 2 Quad CPUs.

The Phenom X4 9000 series is AMD's lower mainstream "Agena" native quad-core processor family. All have 512KB L2 cache RAM per core and 2MB shared L3 cache.

AMD's final Phenom 9000, the overclockable X4 9950 Black Edition, is well positioned in the mainstream but has much higher power consumption than equivalent performing Intel competition.

The list below shows model number, core clock frequency, Thermal Design Power (TDP) in watts, and AMD Business Class nomenclature, if applicable:

Phenom X4 9000 65nm "Agena"
9950 2.6 GHz 125W Black Edition Review
9650 2.3 GHz 95W aka 9600B

The above two processors are the only 65nm X4 models that I recommend.

Athlon II X4 Socket AM3

AMD Athlon II X4 processors are new mainstream processors with zero L3 Cache. They are expected to market later this year.

Except as noted, all models will have 512KB L2 Cache per core and no L3 Cache. More data will be forthcoming.

Tri-Core Processors
Details
Phenom II X3 Socket AM3

Phenom II X3 is now available. This is an excellent tri-core line derived from "cache-defective" X4 CPUs.

This is the triple-core version of the Phenom II series. Except as noted, all models have a total of 1.5 MB L2 Cache (512 KB/core) plus 6MB shared L3 Cache for a total of 7.5MB on-die RAM.

Phenom X3 8000 Socket AM2+

Phenom X3 models are fair lower-cost alternatives for multi-core shoppers.

The Phenom X3 8000 series was an industry first; a triple-core processor made by disabling one quarter of a quad-core Phenom X4 CPU. All models have a total of 1.5 MB L2 Cache (512 KB/core) and 2 MB shared L3 Cache.

Athlon X2 Dual Core Socket AM2

Athlon X2 65 watt and 45  watt processors are good processors for entry level and mainstream systems at low prices. However, the era of Athlon 64-based processors is ending. This microarchitecture is being phased out as more powerful and efficient 45nm K10 models come to market.  

The AMD64/K8 Athlon X2 series are AMD's entry-level and lower mainstream dual-core microprocessor lines for home and office desktop PCs.

Following is a partial listing of Athlon X2 processors with links to Newegg prices. Information displayed includes the model number, internal clock speed, total on-chip Level 2 Cache memory, Thermal Design Power (TDP) in watts (W) if different from the primary category listing, and alternate CPU names for AMD Business Class, if applicable.

Single-Core Processors
Details
Athlon LE Socket AM2

Decent high efficiency single core processors now marketed mainly with low-end OEM systems.

The Athlon 2650e is actually a renamed Sempron processor running at reduced core clock speed and reduced voltage.
In 2003, the single core Athlon 64 revolutionized the PC industry as the first economical 64 bit capable processor for the home and home office computer. The higher efficiency Athlon LE is the newest version.

Athlon "Lima" 65nm 45W TDP
LE-1660 2.8 GHz 1MB
LE-1640 2.6 GHz 1MB aka 1640B

Athlon "Sparta" 65nm 15W TDP
2650e 1.6 GHz 512KB OEM and retail box
This model is designed to compete with the Intel Atom.

Sempron LE Socket AM2

Budget processors for entry-level computers.

This line is being further scaled back and marketed with the lowest of low-end OEM systems.

The Sempron is AMD's entry-level single-core processor. Most commonly offered in Socket AM2 format, current production Sempron processors are 64-bit capable but have reduced onboard Level 2 Cache memory when compared to the Athlon LE series. Low voltage models are known as Sempron LE.

Sempron LE 65nm "Sparta" 45W TDP
LE-1300 2.3 GHz 512KB
LE-1250 2.2 GHz 512KB

Upcoming processors and technologies:

AMD have announced their next micro-architecture will be nicknamed "Bulldozer". Some models will feature a fully integrated graphics product in the processor core known as "Fusion". Bulldozer and Fusion are expected in late 2010 or early 2011. Bulldozer is expected to be based on a 32nm process.

Due to global economic conditions, AMD is splitting into two companies. Their manufacturing division is being moved to Abu Dhabi, UAE. The deal was necessary due to the high-cost of fabrication foundries.
