Processor Breakthrough Could Double Speeds

A new approach to computer processing could double speeds while halving power consumption, according to researchers. The approach could work on existing hardware without needing physical modifications. The research builds on the existing technique ... of multithreading. That's an attempt to overcome the major limitation of computer processors (CPUs). They are broken down into cores (often 2, 4 or 8 cores) but each core can only carry out one task at any specific split-second. Workload Optimized Threading means breaking bigger tasks down into a list of individual steps known as a thread. The ... (view more)

CPU Hyper-threading Reverse Engineered to Spy on Processes

One of the most useful features in computer hardware has a security flaw. It's to do with the way processors handle information. All computing tasks are reduced down to a set of calculations. The central processing unit (CPU) is the "brain" of the ... computer that physically carries out these calculations. Each modern-day CPU has one or more cores , which is essentially multiple "brains" on a single CPU chip. A multi-core CPU means that multiple calculations can be done at once, which reduces the time to carry out a task. Many processors also use a technique called ... (view more)

Which Processor is Better: Intel or AMD? - Explained

Infopackets Reader Bob C. writes: " Dear Dennis, Which processor is better: Intel or AMD? The reason I ask is that my laptop is roughly 6 years old and it's time for me to purchase a new one. That said, I can't seem to find the definitive answer as ... to which processor I should get for my next laptop. AMD seems to have cheaper processors, whereas Intel processors are usually always much more expensive. Can you shed light on which processor is better? " My Response: Update 20180620 : I have updated this article to include new information considering AMD's Ryzen line of ... (view more)
