AMD Announces Project SkyBridge: Pin-Compatible ARM and x86 SoCs in 2015, Android Support This morning AMD decided to provide an update on its CPU core/SoC roadmap, particularly as it pertains to the ARM side of the business. AMD already committed to releasing a 28nm 8-core Cortex A57 based Opteron SoC this year. That particular SoC is aimed at the enterprise exclusively and doesn't ship with an o
As I mentioned in the iPad Air review, Cyclone is a wide machine. It can decode, issue, execute and retire up to 6 instructions/micro-ops per clock. I verified this during my iPad Air review by executing four integer adds and two FP adds in parallel. The same test on Swift actually yields fewer than 3 concurrent operations, likely because of an inability to issue to all integer and FP pipes in par
Making Sense of the Intel Haswell Transactional Synchronization eXtensions TSX Performance Ravi and Marting gave some vague but still rather interesting performance data: According to Intel, using an application that previously used a coarse grained lock (like the older MyISAM storage engines of MySQL) together with a TSX enabled library should improve scaling spectacularly. What's interesting is
When Apple announced the iPhone 5, Phil Schiller officially announced what had leaked several days earlier: the phone is powered by Apple's new A6 SoC. As always, Apple didn't announce clock speeds, CPU microarchitecture, memory bandwidth or GPU details. It did however give us an indication of expected CPU performance: Prior to the announcement we speculated the iPhone 5's SoC would simply be a hi
Solid state storage has quickly been able to saturate the SATA interface just as quickly as new standards are introduced. The first generation of well-built MLC SSDs quickly bumped into the limits of 3Gbps SATA, as did the first generation of 6Gbps MLC SSDs. With hard drives no where near running out of headroom on a 6Gbps interface, it's clear that SSDs need to transition to an interface that can
