"Parallelism" is the keyword underscoring several semiconductor architectures this decade. Now it's the turn of the memory: Rambus announced the availability of "micro-threading" for XDR2 memory, the company's next generation memory technology. Memory clock speeds will catapult to 8 GHz, up from a current maximum of 4.8 GHz of XDR1. Read more
IBM researchers announced that they have developed a device that is capable of delaying the flow of light on a silicon chip, which is considered a critical milestone in creating silicon chips that leverage optical communications to achieve better performance. Read more
Cyberpower sent us a factory-overclocked Phenom II X4 955 system wielding two Radeon HD 4890 cards in CrossFire. We pit the formidable rig against our previous System Builder Marathon Core i7 machine to see if AMD can deliver a viable gaming alternative. Read more
The latest 2 TB hard drives are still expensive, but 1.5 TB disks provide low power consumption at a better cost-to-capacity ratio. We look at offerings from Samsung and Western Digital to determine the value of taking a step down from the flagships. Read more
When a new paradigm like cloud computing or a new platform like Microsoft’s Business Productivity Online Suite (BPOS) comes along, it’s smart to ask tough questions. Read more
With 36 lanes of PCIe 2.0, 3-way SLI could be the X58 chipset’s biggest challenge. If that turns out to be true, is Nvidia’s nForce 200 controller hub, which multiplexes the platform's connectivity, a solution? We compare three configurations to find out. Read more
