X-bit Labs reports users wishing to upgrade to AMD's next-generation Kaveri APU will need to buy a new motherboard as this processor will adopt the FM2+ socket.
As a result of massive changes inside Kaveri, the chips will feature new FM2+ form-factor and will only be compatible with new mainboards with FM2+ sockets, according to a new roadmap update issued by AMD. The new chips will therefore be incompatible with existing mainboards, which means that there will be no upgrade path for systems based on A-series “Trinity” and “Richland” APUs.
Given the fact that Kaveri will feature a number of “firsts” for AMD, a new socket was something logical to expect. What is unclear at this point is whether FM2+ mainboards will have any specific requirements and whether they will be more expensive than existing motherboards with FM2 sockets.
