Revision as of 13:17, 4 June 2011

AMD Fusion is the marketing name for a series of APUs by AMD. There are two flavors of Fusion currently or near availability, one with its CPU logic based on the Bobcat core and the other its CPU logic based on the K10 core. In both cases the GPU logic is HD6xxx, which itself is based on based on the mobile variant of the Mobility_Radeon_HD_5xxx_Series. Fusion was announced in 2006 and has been in development since then. The final design is the product of the merger between AMD and ATI, combining general processor execution as well as 3D geometry processing and other functions of modern GPUs into a single die.[1] This technology was shown to the general public in January 2011 at CES. In the same year AMD will introduce Bulldozer (processor) for Socket AM3+ and for the server market.

AMD Ultrathin Platform was introduced on January 5, 2011, as the fourth AMD mobile platform targeting the ultra-portable notebook market.It features the 40nm AMD Ontario (a 9-watt APU for netbooks and small form factor desktops and devices) and Zacate (an 18-watt TDP APU for ultrathin, mainstream, and value notebooks as well as desktops and all-in-ones) APUs.[4] Both low-power APU versions feature two Bobcat x86 cores and fully supports DirectX11, DirectCompute (Microsoft programming interface for GPU computing) and OpenCL (cross-platform programming interface standard for multi-core x86 and accelerated GPU computing). Both also include UVD dedicated hardware acceleration for HD video including 1080p resolutions.[5][6][7][8] This platform consists of:

AMD mobile Initial platform
Mobile processor Processors
  • Single or Dual-core 64-bit processors codenamed Ontario, Zacate and with the following:
    • made on 40nm CMOS process
    • support for DDR3 1066 MHz memory (only Non-buffered Non-ECC modules)
    • 9W or 18W TDP

"Llano" (32nm)

  • Llano will feature upgraded Stars CPU cores (K10.5) and Redwood-class integrated graphics (codenamed BeaverCreek for the dual-core variants and WinterPark for the quad-core variants). It will be manufactured by GlobalFoundries on their 32 nm SOI process and target the same market as the existing Athlon II line. Like Athlon II, it will be available in dual, triple, and quad-core variants.
  • Llano will have an integrated PCIe 2.0 controller, and a dual-channel memory controller supporting DDR3-1866 memory (except for the E-3250 model, which is limited to DDR3-1600). Each core has 1 MB L2 cache (this may be an exception for the E2-3250 model, which may be limited to 512 KB per core), but will not sport an L3 cache to reduce manufacturing costs. Llano processors will utilize socket FM1.
  • Select models will support TurboCore technology along with a hybrid graphics technology that will allow the GPUs of select A-series APUs to assist a discrete graphics card in graphics processing, when paired with a Northern Islands (Radeon HD 6000 series) discrete graphics card. This is similar to the current Hybrid CrossFireX technology that is available in the select AMD 700 and 800 series chipsets.

HD 6480M may be current model name for older G prefix from the file, thus the G clock info may be applicable.

Future platforms

  • AMD's Financial Analyst Day 2010 revealed a new generation of Fusion APUs for 2012.[10] Further details for the 2012 Fusion line was released in late-May 2011, by technology website DonanımHaber. [11]

(a) "Piledriver" based

  • Piledriver is the codename for the new core design (Enhanced-Bulldozer based) that will replace the Husky (Stars based) cores in the A- and E2-series (Llano).
  • Like Llano, Piledriver based APUs will be manufactured on the 32nm SOI process.
  • Comal is the mobile platform codename for the Piledriver based APU line. It is to replace the Sabine mobile platform.
  • The chipset series for Sabine will be carried over to Comal.
  • The processor package for the mobile variant will be revised from FS1 uPGA package to FS1r2 PGA package.
"Trinity" (32nm), "Weatherford" (32nm), and "Richland" (32nm)

Piledriver based APUs will be divided into three main versions for specific price-points and markets:

  • Trinity covers the performance segment of the APU line. It will replace the Llano based A8-series.
  • Weatherford covers the upper-mainstream segment. Replacing the Llano based A6-series.
  • Richland covers the lower-mainstream segment. It is to replace the Llano based A4-series.

(b) "Enhanced-Bobcat" based

  • To be manufactured on the 28nm bulk process.
  • Deccan is the codename for the Enhanced-Bobcat based platform. It is to replace Brazos platform.
  • The chipset series for Brazos will be carried over to Deccan.
  • The processor package will be revised from FT1 BGA package to FT2 BGA package.
"Krishna" (28nm) and "Wichita" (28nm)
  • For the budget desktop and notebook markets, Krishna will replace the Zacate based E-series. It is expected to be available in 2 to 4-core variants.
  • For the Low-power/tablet/netbook markets, Wichita will replace the Ontario based C-series. It is expected to be available with 1 to 2 core versions.

Competition

The direct competitor of the Intel Atom processor line is the AMD Fusion C- and E-series. The C-series (C-30: single core, C-50: dual cores) has a TDP (9W) similar to the Atom, the higher clocked E-series (E-240: single core, E-350: dual core) comes with a TDP of 18 Watts what corresponds more to an Atom including a dedicated GPU (e.g. ION2, ATI 5430). The processors include a single or dual core 64-bit CPU with out-of-order execution, DDR3 memory controller and an 80-core Radeon GPU. The performance of the E-series is significantly better - up to 326.5% better game performance.[12]

Embedded processors based on the ARM version 7 instruction set architecture (such as Nvidia's Tegra 2 series, TI's OMAP 3 series and Freescale's i.MX51 based on the Cortex-A8 processor, or the Qualcomm Snapdragon and Marvell Armada 500/600 based on custom ARMv7 implementations) offer similar performance to the low end Atom chipsets[dubious – discuss] but at roughly one quarter the power consumption, and (like most ARM systems) as a single integrated system on a chip, rather than a two chip solution like the current Atom line. Although the next-generation Atom codenamed "Pineview" should greatly increase its competitiveness in performance/watt, ARM plans to counter the threat with the multi-core capable Cortex-A9 processor as used in Nvidia's Tegra 2, T.I.'s OMAP 4 series, and Qualcomm's next-generation Snapdragon series, among others.

The Nano and Nano Dual-Core series from VIA is slightly above the average thermal envelope of the Atom, but offers hardware AES support, Virtualization, random number generators, and out-of-order execution. Performance comparisons of the Intel Atom against the Via Nano indicate that a single core Intel Atom is outperformed by the Via Nano which is in turn outperformed by a dual core Intel Atom 330 in tests where the second core is used. The Core 2 Duo SU7300 outperforms the dual-core Nano. [13][14][15][16][17][18][19][20]
