As CES, reaching down for another year, one of the companies we want to touch on is AMD and its plans for the market, laptop and tablet through 2015, as we have discussed previously, AMD You roadmap for 2015 mean is because SoC a new code name Carrizo and cousin lower its power, Carrizo- liter. Both of these chips will share a common form factor motherboard design, and platform, and both are expected to be mid-2015.
One problem we need to address, however, is the question of whether these new cores will be built on a 28nm or 20nm technology. Previously, we reported that AMD will introduce a 20nm die-narrow Puma + processor to its existing 28nm (itself respin Jaguar core which began in 2013). The information came directly from AMD's own announcement regarding the Skybridge, its ambitious attempt to build a single platform for both ARM and x86.
To be more clear, as far as we know, in fact - but I assume that turn out to be incorrect. In particular, I had assumed that when AMD's 20nm version Puma + compatibility with hsa-tech companies will immediately roll into SoC designs for standard laptops. It's clear that AMD now has not been made. Carrizo both the left and Carrizo- 28nm.
Carrizo's changes, clearing up Carrizo-L
Carrizo is a significant improvement on the Kaveri left Carrizo- Beema. The only difference between the Beema and Carrizo- left on AMD's roadmap is a moving platform FT3 BGA FP4 BGA. FP3 BGA is the equivalent of the socket FM2 + + for laptops; FP4 is designed to assume a high degree of energy saving southbridge combination and other power saving features Carrizo.A new feature that AMD has shown at CES is the ability to decode H.265 smoothly on APU Carrizo this system compared to the Broadwell struggling under a workload equivalent. In terms of GPU Carrizo was reported that, based also on and from Tonga core AMD those who date appeared only in the card apart one, which is the Radeon R9 285. We suspected long R9 285 represents a sort of GCN 1.2 with a new, more effective at the front end and support for variable bit Lays floating, which makes sense, the most in the mobile applications that are sensitive strongly to the use of power.
AMD's decision makers hole Kabini APUs at GlobalFoundries earlier this year, now makes a lot more sense. The changes to the core to GlobalFoundries Given time that AMD had to change its design to manufacturing process, the Global Fund's different when building a second version of the core holes in Carrizo- compatible. AMD remains optimistic about the energy efficiency and the use of improved Carrizo - it does not say much about the left Carrizo- or give any indication of how it is different from the core + Puma any current.
Such as for projects Skybridge it's obvious there are still on schedule and coming in 2015, but without the mobile platform to expand chip 20nm new we have to wonder what kind of absorption type AMD hoped for. The company was supposed to ship produce Cortex-A57 «Seattle" CPU server, its the end of 2014, but if it did so, it does not make a peep about it. True, the press release of the server does not command the same kind of attention that the customer is central to, but AMD has made a great deal of noise about how ARM and server thick there is central to its plans to get the market share of the new. She Lisa Su has a good reason to emphasize posted and the success of her company in the area that made the silence AMD all your doubts greater.
For now, we assume that the Skybridge still on track for a 2015 debut, but it now seems that the core company Puma + + 20nm with support hsa complete will end up in the hands, far less than the first, which we expect - and Carrizo rather than Carrizo- left, seems AMD you start an important directed into the year 2015.
