The AMD Family 10h, or K10, is a microprocessor microarchitecture by AMD based on the K8 microarchitecture.[1] The first third-generation Opteron products for servers were launched on September 10, 2007, with the Phenom processors for desktops following and launching on November 11, 2007 as the immediate successors to the K8 series of processors (Athlon 64, Opteron, 64-bit Sempron).

Nomenclature

It appears that AMD has not used K-nomenclature (which originally stood for "Kryptonite" in the K5 processor[2]) from the time after the use of the codename K8 for the AMD K8 or Athlon 64 processor family, since no K-nomenclature naming convention beyond K8 has appeared in official AMD documents and press releases after the beginning of 2005.

The name "K8L" was first coined by Charlie Demerjian in 2005, at the time a writer at The Inquirer,[3] and was used by the wider IT community as a convenient shorthand[4] while according to AMD official documents, the processor family was termed "AMD Next Generation Processor Technology".[5]

The microarchitecture has also been referred to as Stars, as the codenames for desktop line of processors was named under stars or constellations (the initial Phenom models being codenamed Agena and Toliman).

In a video interview,[6] Giuseppe Amato confirmed that the codename is K10.

It was revealed, by The Inquirer itself, that the codename "K8L" referred to a low-power version of the K8 family, later named Turion 64, and that K10 was the official codename for the microarchitecture.

AMD refers to it as Family 10h Processors, as it is the successor of the Family 0Fh Processors (codename K8). 10h and 0Fh refer to the main result of the CPUID x86 processor instruction. In hexadecimal numbering, 0Fh (h represents hexadecimal numbering) equals the decimal number 15, and 10h equals decimal 16. (The "K10h" form that sometimes pops up is an improper hybrid of the "K" code and Family identifier number.)

Schedule of launch and delivery

Timeline

Historical information

In 2003, AMD outlined the features for upcoming generations of microprocessors after the K8 family of processors in various events and analyst meetings, including the Microprocessor Forum 2003.[7] The outlined features to be deployed by the next-generation microprocessors are as follows:

In June 2006, AMD executive vice president Henri Richard had an interview with DigiTimes commented on the upcoming processor developments:

Live demonstrations

On November 30, 2006, AMD live demonstrated the native quad core chip known as "Barcelona" for the first time in public,[8] while running Windows Server 2003 64-bit Edition. AMD claims 70% scaling of performance in real world loads, and better performance than Intel Xeon 5355 processor codenamed Clovertown.[9]

On January 24, 2007, AMD Executive Vice President Randy Allen claimed that in live tests, in regard to a wide variety of workloads, "Barcelona" was able to demonstrate 40% performance advantage over the comparable Intel Xeon codenamed Clovertown dual-processor (2P) quad-core processors.[10] The expected performance of floating point per core would be approximately 1.8 times that of the K8 family, at the same clock speed.[11]

On May 10, 2007, AMD held a private event demonstrating the upcoming processors codenamed Agena FX and chipsets, with one demonstrated system being AMD Quad FX platform with one Radeon HD 2900 XT graphics card on the upcoming RD790 chipset. The system was also demonstrated real-time converting a 720p video clip into another undisclosed format while all 8 cores were maxed at 100% by other tasks.[12]

Sister microarchitecture

On the December 2006 analyst day, Executive vice president Marty Seyer announced a new mobile core codenamed Griffin launched in 2008 with inherited power optimizations technologies from the K10 microarchitecture, but based on a K8 design.

TLB bug

In November 2007 AMD stopped delivery of Barcelona processors after a bug in the translation lookaside buffer (TLB) of stepping B2 was discovered that could rarely lead to a race condition and thus a system lockup.[13] A patch in BIOS or software worked around the bug by disabling cache for page tables, but it was connected to a 5 to 20% performance penalty. Kernel patches that would almost completely avoid this penalty were published for Linux. In April 2008, the new stepping B3 was brought to the market by AMD, including a fix for the bug plus other minor enhancements.[14]

Features

Fabrication technology

AMD has introduced the microprocessors manufactured at 65 nm feature width using Silicon-on-insulator (SOI) technology, since the release of K10 coincides with the volume ramp of this manufacturing process.[15]

Supported DRAM standards

The K8 family was known to be particularly sensitive to memory latency since its design gains performance by minimizing this through the use of an on-die memory controller (integrated into the CPU); increased latency in the external modules negates the usefulness of the feature. DDR2 RAM introduces some additional latency over DDR RAM since the DRAM is internally driven by a clock at one quarter of the external data frequency, as opposed to one half that of DDR. However, since the command clock rate in DDR2 is doubled relative to DDR and other latency-reducing features (e.g. additive latency) have been introduced, common comparisons based on CAS latency alone are not sufficient. For example, Socket AM2 processors are known to demonstrate similar performance using DDR2 SDRAM as Socket 939 processors that utilize DDR-400 SDRAM. K10 processors support DDR2 SDRAM rated up to DDR2-1066 (1066 MHz).[16]

While some desktop K10 processors are AM2+ supporting only DDR2, an AM3 K10 processor supports both DDR2 and DDR3. A few AM3 motherboards have both DDR2 and DDR3 slots (this does not mean that both types can be fitted at the same time), but for the most part they have only DDR3.

Lynx desktop processors only support DDR3, as they use the FM1 socket.

Server

Successor

See main article: AMD Fusion, Bulldozer (microarchitecture) and AMD Bobcat. AMD discontinued further development of K10 based CPUs after Thuban, choosing to focus on Fusion products for mainstream desktops and laptops and Bulldozer based products for the performance market. However, within the Fusion product family, APUs such as the first generation A4, A6 and A8-series chips (Llano APUs) continued to use K10-derived CPU cores in conjunction with a Radeon graphics core. K10 and its derivatives were phased out of production by the introduction of Trinity-based APUs in 2012, which replaced the K10 cores in the APU with Bulldozer-derived cores.

Family 11h and 12h derivatives

Turion X2 Ultra Family 11h

The Family 11h microarchitecture was a mixture of both K8 and K10 designs with lower power consumption for laptop that was marketed as Turion X2 Ultra and was later replaced by completely K10-based designs.[1]

Fusion Family 12h

The Family 12h microarchitecture is a derivative of the K10 design:[36] [37]
