More on AMD Carrizo processors
Facing enormous competition by Intel on the desktop processor field where the Intel Haswell processor rules unchallenged, AMD has clearly turned to making APUs abandoning to a large extent the development of high-end desktop processors. In most cases AMD APUs come with multiple cores, decent integrated graphics and enough power for everyday use. The latest proof is the Kaveri chip, which was released not so long ago.
Fortunately for AMD fans Kaveri will not be the last AMD chip so in 2015 the US company will reveal Carrizo that will replace Kaveri. Thanks to a few online sources more information on these chips has been spread giving a better idea as to what to expect when the time comes.
Carrizo will undoubtedly be an interesting processor. It will come with up to four Excavator computational cores, support for AVX2, BMI2, MOVBE and RDRAND instructions, 28 nm tech production process, integrated GCN graphics, and support for both DDR3 and DDR4 memory. The chip will be able to work with up to DDR4-2400 memory and its BGA version will come with an integrated South Bridge too. The bridge will offer support for two SATA 3.0 ports, four USB 3.0 ports, eight USB 2.0 ports and a SD card interface. The FM2+ version of the processor will have its own separate south bridge on the motherboard so the integrated one will not work on these chips. Unfortunately for some users Carrizo will support just 16 PCI-E 3.0 lines. The chip will connect to the south bridge using four of them, 8 will go for the connection to an external graphics card and another 4 will be left for other devices.
