Just yesterday, we addressed the dubious claim that Intel's Clover Trail+ low power mobile processors had somehow seized a massive lead over ARM's products and we noted some of the suspicious discrepancies in the popular AnTuTu benchmark. It turns out that the situation is far shadier than we initially thought. The latest benchmark version isn't just tilted to favor Intel -- it seems to flat-out cheat to accomplish it. Anandtech forum user Exophase went digging into the benchmark source code to determine why the latest version showed such one-sided gains in favor of x86 processors. AnTuTu is basically...

Want to scare the life out of a programmer friend? Just utter the words "multi-threading" into their ear - it works every time! Alright - that's a bit of an exaggeration, but writing multi-threaded code is one of the biggest challenges a programmer can ever face. The reason boils down to the fact that for the longest time, everyone wrote code that best-suited single-core processors - which just happened to get faster every year. When we reached the peak of processor frequency a number of years ago, multi-core processors became the only way to move forward. While these CPUs are excellent for...

A key Microsoft kernel architect, David Probert, has come out with a surprising statement regarding Windows' ability to harness multiple cores. While Windows has taken advantage of multicore technology for over a decade, Probert notes that users rarely see the performance that they should. "Why should you ever, with all this parallel hardware, ever be waiting for your computer?" Probert asked in a presentation last week at the Universal Parallel Computing Research Center in Champaign-Urbana. Each successive OS release from Microsoft has improved multicore scaling but bottlenecks regularly occur...

Whether AMD or Intel is on top of the CPU world, there's one CPU related area in which Intel has historically been very successful: Compilers. With today's press release, it seems that Intel is taking their current focus on multi-threading even further: "Intel Corporation today announced the availability of two software products that help developers efficiently create more reliable, high-performing applications that speed up a computer's responsiveness. The Intel® C++ Compiler and Fortran Professional Editions bring together a unique combination of highly optimizing compilers, performance libraries...
