If one regards the chip set/complete PC market, a striking difference shows up between Intel and AMD - Intel offers own, diagram chips integrated into the chip set, while this is somewhat stiefmütterlich treated with AMD.
From safe source it became us to course-carry that itself this to 23. /24. April in Tunis to change is. Speculations over the delay of the R600 there were already many, now seems the reason to be finally clarified. AMD/ATI plans to offer beside the R600 and the Low Cost variants RV610 and RV630 also, a K8L (Barcelona) with integrated R600 diagram. Similarly as at that time with the memory CONTROLLER in the K8 core one wants to integrate now the diagram into the processor, in order to profit from shorter signal paths as well as fast internal communication to. Here the diagram maps concern with RV630 chip a abgespeckten R600 core, which should be however faster, as. The R600 falls back dynamically to DDR2 RAM and can split off and depending upon need up to 512 megabyte. Further AMD plans also to make possible in systems with several K8L processors a Crossfire bridge so that the diagram core in the second processor does not use dormant energy. One became here the NUMA ability of the K8-Architektur on 64-Bit systems too uses makes, around as fast an access to the DDR2 as possible memory slower compared with DDR3 and DDR4 to make possible. AMD calls this concept GoC (Graphics on chip), as well as CoC (Crossfire on chip), the processor with integrated diagram carries the code name K8L-V.
The delay of the presentation of the R600/RV610/RV630 is to therefore come that it is to have given unforeseeable difficulties with the integration of the diagram chip to the processor. On the part of AMD one insisted however on it, the entire R600 pallet presenting inclusive Low Cost at the same time and integrated diagram. Thus among other things the communication protocol was revised several times and supplemented around the Crossfire ability. Also it will give the possibility of equipping and of making with this then over the PCIe bus Crossfire a unit processor possible with a second R600. No more main memory is split off, but is not used the DDR4 RAM for both diagram chips, existing on the diagram map - only if this memory is enough any longer is additionally for texture pagings of the DDR2 memory of the system is used. First systems with K8L-V chip should be available to at the end of 2007 in large quantities.
