Find your Windows Experience Index scores in Windows 8.1

The Windows Experience Index benchmark tool has been around since Microsoft first introduced Windows Vista. The benchmark measures your PC's performance and breaks it down into five categories: processor, memory, graphics, gaming graphics, and hard disk. Though it's not known as an especially accurate measure of PC performance, particularly when comparing scores with other systems, it can be a useful tool to identify a hardware deficiency.

Starting with Windows 8.1, Microsoft decided to remove the graphical interface to the Windows Experience Index. The underlying benchmark utility, known as the Windows System Assessment Tool (WinSAT), is still there … Read more

Top500 supercomputer rankings await speed-test shakeup

Monday's update to the list of the 500 fastest supercomputers in the world showed only a single new system in the top 10. But bigger changes are afoot, because list organizers have released an entirely new speed test to gauge the systems.

For two decades, a group of academic researchers have used the Linpack benchmark to gauge performance on the Top500 list. On Monday, the Top500 organizers released a new test called High Performance Conjugate Gradient (HPCG) that's designed to better predict a supercomputer's real-world utility.

One change coming with the new benchmark: It's likely to … Read more

Google modernizes Octane JavaScript speed test

Google has updated its Octane speed test for measuring JavaScript performance, expanding its scope and rounding out the benchmark with computing tasks from rival browser makers Mozilla and Microsoft.

With the expanded scope, Google tries to measure not just execution performance but also delays that can trip up Web pages and Web apps, Google said in its Octane 2.0 announcement Wednesday. Specifically, it added new tests to gauge sluggishness from the initial compilation of JavaScript programs into machine-executable code and from the memory-scrubbing operation called garbage collection.

iPad Air benchmarks show 80 percent speed bump over iPad 4

The iPad Air is 80 percent faster than the fourth-generation iPad, say new benchmark tests.

Running the new iPad through the paces via Geekbench 3 tests, Primate Labs found that the tablet comes close to reaching Apple's promise of doubling the speed of the iPad 4.

The iPad Air is powered by an A7 processor, just like the iPhone 5S. But the new iPad runs at 1.4GHz -- which is 100MHz faster than the 5S, Primate Labs founder John Poole said on Wednesday. He said he's not sure whether the iPad Air's processor is faster due … Read more

Samsung: We didn't cheat on Galaxy Note 3 benchmarks

Samsung has been forced on the defensive yet again over reports that its top-notch smart phones are cheating at benchmark tests.

The Korean company has denied its Galaxy Note 3 superphone exaggerates its performance when it detects well-known benchmarks running, as was claimed Tuesday in an extensive, well-documented report on the Web site Ars Technica.

"The Galaxy Note 3 maximises its CPU/GPU frequencies when running features that demand substantial performance," Samsung said in a statement to CNET UK.

After chip benchmark revised, Samsung and ARM gain on Intel

An Intel chip showed slower performance when tested against the processor in Samsung's Galaxy S4 after a popular benchmark was revised.

EE Times posted a story titled "Has Intel really beaten ARM?" on Wednesday that called into question the widely-used AnTuTu Benchmark. In June, a market research firm published results of an exercise using the benchmark that found an Intel chip greatly outperforming ARM.

The EE Times article disputed the results that pitted the Lenovo K900, with an Intel Atom Z2580 smartphone chip, against the Samsung Galaxy S4, with that company's Exynos 5 Octa processor.

Debate sparked about benchmark for Intel, ARM chips

Nothing like a debate about processor benchmarks to get enthusiasts blood up.

EE Times posted a story titled Has Intel really beaten ARM? on Wednesday that calls into question the use of the widely-used AnTuTu Benchmark.

"There has been a considerable amount of press around recent AnTuTu benchmark results claiming, Intel...processor outperforms Nvidia, Qualcomm, and Samsung," wrote the EE Times story's author analyst Jim McGregor of Tirias Research.

The original article states.

"The benchmarks were impressive but the real surprise was the current consumption recorded during the benchmarks; the new [Intel] processor not only outperformed … Read more

Haswell MacBook Pro benchmarks show modest performance gains

At its WWDC, Apple introduced its upcoming lines of MacBook systems that use the next-generation Haswell processors from Intel. With these new CPUs, Intel not only offers significant boosts not only in performance, but also has focused on power efficiency.

Last month MacRumors reported Geekbench 2 benchmark results for the new 2013 MacBook Air, which show about a 4 to 7 percent increase in performance with the new chips. While not a significant jump in speed, this performance did come with a massive increase in battery life for the systems, which has been Apple's focus and selling point for … Read more

Qualcomm Snapdragon 800 incinerates the competition

The Qualcomm Snapdragon 800 will destroy your mobile processor. Not literally, of course. I'm strictly referring to its ability to render real-time graphics so fast as to make your current mobile processor -- on your phone or tablet -- embarrassingly pokey in comparison.

At a benchmarking event in San Francisco, Qualcomm allowed me and others in attendance to run a benchmarks on a reference Mobile Development Platform (MDP) tablet housing its latest Snapdragon 800 system-on-chip (SoC). The results speak for themselves; however, I should warn that these are only benchmark results (3DMark and GFXBench, specifically) and don't necessarily … Read more

3Dmark for Android separates performance champs from chumps

As a lifelong gamer, 3D performance (and by "3D" I mean polygonal, not stereoscopic) in tablets is something of particular interest to me. Over the last couple of years, I've watched mobile devices increase in performance, getting closer and closer to the capabilities of PCs and consoles. Judging by their performance histories, tablet and smartphone 3D performance is likely to exponentially increase over the next few years and we may soon be carrying around devices that are as powerful as an Xbox 360 (or more powerful) right in our pockets.

Futuremark's latest version of its long-running … Read more
