The conference ISSCC 2017 AMD has shared information on the extent of the crystal and on the composition of a number of elements in 4-core processor Zen architecture. AMD Processor with 4 cores supports 8 processing threads (two threads per core) is made with the standards of 14 nm is clearly the second-generation and, most likely, at the facilities of GlobalFoundries company . The solution was compared with an Intel processor, which is also released with a second-generation 14-nm process
technology. According to AMD data, its decision to fit the area of 44 mm2, while Intel chip occupies an area of 49 mm2.
According to analysts, and even Intel company representatives , which overheard at a conference reporter Internet resource EE Times, processor design Ryzen definitely looks smaller Intel development. Whether this translates into AMD gains in terms of improved cost and other bonuses. In the meantime, it must be acknowledged that AMD came forward, even against the backdrop of slightly less dense 14-nm process technology GlobalFoundries (Samsung).
Even from the comparative table shows that AMD has been in a worse situation than Intel. Thus, transistor contacts step (CPP) in the case of AMD processor 8 nm greater than the transistors in the Intel processors. Step metal contacts on the AMD chip total more - by as much as 12 nm. With all that AMD managed to squeeze everything on the same chip . In the same L2 cache twice more than at Intel processors and thus increase the area under the memory explicitly twice. A L3 cache,
with an equal amount in the case of AMD solution takes on a chip 16 mm2, while the L3 on the Intel chip fitted within an area of 19.1 mm2. And the area of the standard 6-transistor SRAM cell from AMD's larger than from Intel. Smoothen fiction.
It should be said that AMD at the conference talked a lot about the new scheme of using switched-capacitor technology, the capacity of which it was able to reduce by 15%. For the production of more advanced integrated capacitor is switched to the capacitor of metal-insulator-metal. This helped to reduce the operating voltage and improve power management and frequency control. Perhaps the best secret AMD density solutions that switched capacitor circuits can greatly reduce the area of ??the
integral solutions, due to the failure of resistors in circuit design. Related Products :
