From PC World: With AMD's processors still stuck on an aging 28nm manufacturing process, it needs some innovation to catch up to Intel—and the company thinks it has the elements to do so with "Carrizo," a high-end integrated chip that the company will debut in 2015.
AMD said that Carrizo and a derivative, Carrizo-L, will debut sometime in 2015. AMD disclosed the new additions at an event in Singapore on Thursday, adding that it will reveal more details—presumably speeds and price—in the first half of 2014.
Carrizo will be fully HSA 1.0 compliant, meaning that it will deliver on the Heterogenous Systems Architecture that AMD has talked about for some time. With HSA, the GPU can also be tapped to perform compute functions, which the company claims will deliver far more performance than the speed increases from moving to finer CPU manufacturing technologies alone. Intel, of course, is moving to its second-generation 14nm processor technology with upcoming chips like the Core M.
In June, AMD launched Kaveri, a family of what it called its first enthusiast-class APUs. Kaveri's CPU cores are based on AMD's "Steamroller" microarchitecture, while its GPU cores use the same architecture as AMD's Hawaii-class discrete graphics processors (dubbed Graphics Core Next). The “Carrizo” processor will integrate the new x86 CPU core codenamed “Excavator” with next generation AMD Radeon graphics, while the Carrizo-L derivative will use the Puma+ core and AMD Radeon R-Series GCN GPUs for mainstream configurations, AMD said.
