AMD, on the brink of making a start with its first desktop CPUs made on the 45nm manufacturing process, seems to have updated time-frames in which it will introduce new CPUs and manage inventories of currently available CPUs. Data compiled by DigiTimes from sources in the motherboard manufacturing industry points towards the following in 2009:

• The introduction of four new SKUs in the months of April, that include Athlon X4 (Propus core) 615 and 605, Athlon X3 (Rana core) 420 and 410, followed by Athlon X2 (Regor core) 240 and 235 in June
• Last orders for Phenom X4 9850 and 9950 (140W) to be taken in March, Phenom X4 9750, 9850 (95W) and 9950 (125W) will be in June, before which Phenom II X4 920 and 940 in May (in most likelihood replaced by models 925 and 945)
• Phase-out of Phenom X3 8450 and 8550 started, that of Phenom X3 8650 in March followed by Phenom X3 8850 and 8750 in June
• Last order notice for Athlon X2 4450e to be issued in March

AMD processors finally get to address DDR3 memory on the new AM3 socket. Compatible processors under the Phenom II and Athlon X3, X4 banners that come in AM3 socket packages, will run initially on updated AMD 7-series chipset variants, and later be succeeded by the the company's RD890 and RS880 chipset cores. HKEPC compiled some information on the RS880 core logic. The "RS" prefix for AMD GPG chipsets mark the presence of integrated graphics. Based on the performance efficiency of the RSx80 dice, they're branded into the mainstream RSx80 product (eg: RS780 for AMD 780G), RSx80C for a value product (eg: RS780C for AMD 740G) and a high-end RSx80D (eg: in AMD 790GX).

The RS880 will use feature-set refresh, though will embed a rather dated RV620-class graphics processor. The IGP will have DirectX 10.1 API compliance. Specifications-wise it is identical to the RS780, both sport 40 stream processors, 8 texture address and 4 texture filtering units, though the core speed on the RS880 is expected to be significantly higher. The feature-set refresh, as stated earlier, includes support for Universal Video Decoder 2 (UVD-2), in addition to 100% hardware acceleration for VC-1, H.264 and MPEG-2 bitstream decoding. Also provided is video dynamic-contrast. The IGP supports HDMI with audio routing, and DisplayPort. The chipset will be released in Q3 2009. Like the current RS780, the RS880 will be manufactured on the 55nm node of TSMC. It will be used on motherboards with companion SB710 or SB800 southbridge chips.

A lot has been said about the launch schedules of AMD's upcoming 45nm desktop processors over the last fortnight. While the company itself slated its 45nm desktop CPU range to kick-off on January 8 2009, skeptics think otherwise saying it could take longer for AMD to have sufficiently stocked up inventories in retail channels.

HKEPC compiled a list of tentative order availability. time-frames for the 45nm CPUs sourced from PC manufacturers, which shows that the company launches Phenom II X4 940 on Jan. 8, while most of the product launches are concentrated in the months of February and April, 2009. Starting those months, channel vendors will be able to place bulk orders for those processors, to stock up inventories. Also pictured is the die-shot of AMD Deneb, and a picture showing the differences between the AM3 and AM2+ pin-grids (AM3 on the leftHS, AM2+ on rightHS).

AMD would be releasing its 45nm silicon-based desktop CPUs, built on the Deneb, Propus, Heka, Rana and Regor cores, to bring out quad-core, triple-core and eventually dual-core processors. AMD has discarded the 5-digit number scheme that was earlier reported, and in its place, adopted a three-digit scheme. The quad-core Deneb chips get a 9xx model number and 8xx number depending on the clock-speeds and cache size, Propus-based chips get the Athlon X4 branding.

Heka-based chips get Phenom II X3 7xx branding, with Rana getting Athlon X3 4xx. Regor dual-core trails with Athlon X2 2xx. It is important to note that AMD seems to have made a critical change to the Deneb core, releasing 2 models based on cache-arrangements. The first kind features a total of 8 MB cache (4x 512K L2 + 6M L3) and one with 6 MB total cache. To learn more about the other cores, please refer to our older article getting into details (here).
