AMD Stars generation processors to support DDR2 1066 and the SSE4A
AMD the K8 tabletop processor product has reached long time of the four years historical, not merely is AMD snatches next four landscape, supports to Intel the new generation of Core micro overhead construction is only then caught up with, 蝯� to is although defeats especially the glory. In order to again seizes the processor potency emperor position of, the AMD plan the third season promotes the next generation Stars core tabletop processor in 2007, except further improves on the micro overhead construction, main engine board industry disclosure AMD (Joint Electron Device Engineering Council) is soliciting support to JEDEC, it looks DDR2-1066 officially lists as one of field specifications, lets next generation Stars officially support DDR2-1066 in the specification.
According to the main engine board industry pointed out that, AMD old has the K8 micro overhead construction core to change name is the Cities core, but new generation of micro overhead construction product then the official naming is the Stars core family, including four cores Agena, Gao Chiehshuang core Kuma, basic level double core Rana and basic level Spica single core.
The Stars core except promotes Hyper-Transport to 3.0 edition, north the command between the bridge and the processor transmission speed by the 2GT/s promotion to 5.2GT/s outside, Instruction the fetch promotion to the 32B width, and further promotes Branch Prediction and the Out-of-order load execution accuracy, moreover is highest may operate 4 Double Precision FLOPS per cycle, four SSE operation and Load per cycle and so on, will be able in under the same time arteries to bring the product the certain degree the potency promotion.
Although the micro overhead construction has carried on the improvement project, the processor connection changes to Socket AM2+, but in fact AM2 and the AM2+ product actually may be mutually compatible. According to the main engine board industry expression, according to AMD the official AM2r2 specification, the AM2+ connection main engine board product will be able for at the same time compatible next generation AM3 processor, but AM2 was unable to transit, has become two main distinctions.
The most worth noting is, the AMD original tabletop processor development main source, after AMD will be able to continue the AM2 connection directly to promote the support simultaneously to support DDR2 and DDR3 the memory body AM3 processor, but AMD also understood in fact will popularize to DDR3 most soon only then can achieve to 2009, Before this the DDR2 memory body will be still the market leadership, therefore AMD will promote only supports DDR2 the memory body the AM2+ processor, not merely might simplify the product design, lets the product be possible to shift to an earlier time goes on the market, and will give AM3 processor more time to make the preparation for the next generation DDR3 memory body support, 蝯� to will be the unwise action.
Because JEDEC only lists as DDR2-800 the DDR2 memory body 璅∠� highest specification, the high velocity memory body only can meet the stick by the DDR3 memory body, the command remembered in the body specification the far inferior new generation supports DDR3-1066 Intel the Beaelake platform. But, according to the main engine board industry disclosure, AMD finds out horse whip of the resistance, in the new generation of Stars processor joins the primary DDR2-1066 memory body support, and diligently is soliciting support JEDEC to list as the official field specification DDR2-1066, enables the Stars core perfectly justifiable to support DDR2-1066.
Because the Intel next generation 45 憟� rice products will be able officially to support the SSE4 instruction, will be able some 48 to refer is joined, actually will the next generation Stars core whether support SSE4 to become in the market a big question, but AMD also to the last week to the main engine board industry disclosure, the Stars core will be able to support SSE4A, it used in the Intel 64 optimizations instructions AMD SSE4 different occupying to the part to obliterate, but drew a chart, the image code, the 3D operation, the game and so on the multimedia instruction can quite same not less than be compatible.
According to the main engine board industry expression, after AMD estimated the Star core will promote the first quarter to be able to occupy above the AMD basic level the product to produce goods the quantity approximately 1 tenth, because AMD will be able to promote the basic level Rana core to the fourth season, estimated the Stars core will be able further to promote to occupy above the AMD basic level the product to produce goods the quantity approximately 2 tenths. In addition, AMD the anticipated Stars core at the beginning of 2008 will accelerate to popularize, estimated in 2008 the first season Stars core will be able to occupy above the basic level six tenths shares, will be official and the old product carries on in turn act.
