AMD announces its Spider Platform in what could be its biggest launch of all time
Tomorrow marks the launch of AMD's platform launch, codenamed
. The launch consists of three components: AMD Phenom processors, the ATI Radeon HD 3800 graphics processor and AMD 7-Series desktop chipsets.
The first new AMD desktop architecture in four years will debut with the Phenom 9500 and Phenom 9600. Both chips feature a 95-Watt thermal envelope and a shared 2MB L3 cache.
The AMD Phenom 9600 ships with a 2.3GHz operating frequency, while the Phenom 9500 features a slightly lower 2.2GHz clock. Both processors run on HyperTransport 3.0 and feature a total 2MB L2 cache; 512KB per core. The chips also come with an integrated DDR2 memory controller and support speeds up to the DDR2-1066 specification, which is still pending JEDEC approval.
the Phenom 9600 at a retail price of $322.00 and the Phenom 9500
that a 2.4GHz Phenom, dubbed the Phenom 9700, would also launch on November 19, however last minute roadmap updates indicate this chip will come in December instead.
These two Phenom processors are part of AMD's first-generation, 65nm
. In the second-half of 2008 AMD will announce its
, which will be a migration of the current K10 core to the 45nm node.
lineup consists of five variants, including quad-core
. The second-generation
CPUs will also include an
integrated DDR3 memory controller
, a first for AMD.
AMD's Spider Platform launch also includes the official announcement of its ATI Radeon HD 3800 Series. The launch of the Spider platform will add two new video cards to AMD's lineup, the ATI Radeon HD 3870 and Radeon HD 3850.
new Radeon series
received overwhelmingly positive feedback during AMD's November 15 media event. Newegg representatives tell
the company sold out all of its stock on the first day, but is quickly replenishing inventory.
To round off the launch of the platform, AMD also announced its 7-Series desktop chipsets. The AMD 790FX targets the ultra-enthusiast market segment, and corporate guidance sets the retail price of 790FX boards between $150-250. Several partners already announced boards
supporting this new chipset earlier this year
AMD designates the AMD 790X as its performance chipset, slotted just below the 790FX. AMD guidance states this chipset will run the consumer between $99-150. The mainstream AMD 770 chipset will not see store shelves for several months, but AMD claims this chip will round off the mainstream segment for AMD chipsets.

on an AMD64 system the RAM is already connected to the CPU through its own dedicated bus (the onboard memory controller of the CPU), thus th eonly really bandwidth intensive thing for the mobo chipset is handling traffic between CPU and GPU.
the amount of bandwidth is determined by the slowest part in the chain, meaning that if the GPU can accept data at 10GB/sec but the mobo chipset can only send it at 5, then the bandwidth is 5GB/sec.
if the CPU and GPU are on teh same die than this all still applies; but it is much easier connecting things on-die than through the motherboard, as there is no need for long traces in the mobo that can become hot and may cause interference. all modern mobos are actually 4 or more layers of board sandwiched together because there are just so many traces (and the larger traces need to be cut up into smaller ones to avoid heat issues). putting it all on the same die means the manufacturer is not limited by the mobo anymore, and thus bandwidth would be whatever the manufacturer would want it to be. latency would also be reduced.
at the moment there is no need for such a device yet, but cost also factors in: if you want to build a low-cost PC then the fewer separate components=the lower price.
