Dual-core ARM Cortex-A15 faster than Intel Atom and quad-core Cortex-A9

by: Gary SimsDecember 3, 2012
When Apple released the iPhone 5 it didn't contain a quad-core CPU as many people had expected, however Apple did claim that the new phone was up to twice as fast as its predecessor. The most likely reason that Apple could make such a claim is that its A6 CPU uses the Cortex-A15 architecture. With the recent release of Google's new Chromebook, which is powered by Samsung's Cortex-A15 based Exynos 5 Dual (Exynos 5250), the benchmarking gurus have now had a chance to really test the new architecture from ARM and the results are amazing.

Microsoft’s Surface pushes Acer to be more aggressive about Chromebooks

by: LucianSeptember 17, 2012
Acer had been one of the companies to be the most vocal about their critique of the Surface, blasting Microsoft over its decision to suddenly become a tablet-maker. Now they want to show Microsoft that they've got an alternative in ChromeOS, so they're going to heavily promote their next-gen Chromebooks supposed to come out this October.

Cortex A9 beats Intel Atom at the same clock speed

by: LucianSeptember 4, 2012
An independent user tested a dual core 1.0GHz Cortex A9 chip against a dual core Intel Atom chip running at the same speed. The results may seem surprising as it seems common knowledge that Atom would beat ARM chips in performance clock per clock, but as I've said before, Intel is not yet ready to take on the mobile market with its Atom chips.

Samsung reveals Exynos 5 Dual (5250): what you need to know about the world’s first Cortex A15 SoC

by: LucianAugust 9, 2012

Samsung has just released the whitepaper for their long-awaited Exynos 5250 SoC, now called the Exynos 5 Dual, and there’s a lot of interesting information to be discovered in it.

The Exynos 5 Dual will be the world’s first Cortex A15-based chip, when it will ship later this year, presumably inside the 11.8-inch tablet Samsung is going to launch later this year. Samsung had to wait for this A15-based chip to support the very high WQXGA (2560×1600) resolution of the Galaxy Tab 11.6.

Some of the most important features of the newly unveiled Exynos 5250 are:

Dual-core 1.7 Ghz Cortex A15 CPU Mali T604 GPU OpenGL ES 3.0 OpenCL 1.1 full [...]

UMC and TSMC to move to FinFET at 20nm

by: LucianAugust 1, 2012

Intel went FinFET (or tri-gate transistors as they call them) at 22nm with Ivy Bridge, and now the #1 foundry, TSMC, and the #2 foundry, UMC, will also go to FinFET for the next gen 20 nm process. However, mass production of 20nm ARM chips will probably not happen until 2014, considering 28nm is barely here in 2012, and it usually takes 2 years for the new process technology to be ready.

Apparently, the planar FinFET technology that these foundries intend to use is better suited for mobile SoC’s, like the ones from ARM, and it should bring a performance improvement of at least 15%-20% over Intel’s own FinFET [...]

ARM and Allwinner work together to jumpstart the cheap Android tablet market

by: LucianJune 21, 2012

Allwinner is a chip maker not a tablet maker, but right now, the Chinese company’s products are a very popular choice for ~$100 Android devices, whether we’re talking about cheap Android tablets or those sub-$100 pocket PCs based on ARM chips.

Allwinner chips usually have a 1-1.5 Ghz Cortex A8 CPU, coupled with a powerful Mali400 GPU (same as the one in the Galaxy S2), which enables even low-end tablets to smoothly run ICS and to play any type of HD content flawlessly.

Analysts expect that 40 million tablets will be shipped in China alone this year, and it seems Allwinner’s chips will be in 60% of those tablets (or roughly 24 million). [...]

ARM’s big.LITTLE processing technology is coming of age

by: LucianJune 13, 2012

ARM has been getting a lot of praises on their idea for the big.LITTLE technology, because it shows them not only a leader in mobile chip performance, but they are moving forward with higher and higher performance. Their chips still remain low-power overall and in the future they claim they will achieve this through big.LITTLE technology.

Big.LITTLE means they are going to pair up a very low-power in-order CPU like Cortex A7, with their most powerful out-of-order CPU yet, the Cortex A15. This should work much in the same way that Nvidia’s 4+1 technology works, with their extra core companion. The difference is that Nvidia used the same CPU for both types of [...]

TI compares their upcoming OMAP 5430 chip with Apple’s A5X

by: LucianJune 4, 2012

TI announced the OMAP 5430 for the first time back in 2010, and I remember how excited people were about it, even though they should’ve moderated their excitement a little bit. The chip wasn’t supposed to come out for 2 years and who knows what we would see until then! Well, the OMAP 5430 is getting closer and closer to being introduced into the market, and TI is starting to show us more demos of it to get us excited about it once again.

The test ahead of Computex, seems to pit a tablet running the dual core Cortex A15 with an overclocked PowerVR SGX 543MP2 GPU versus the new iPad with the dual core A9 CPU and a PowerVR SGX 543MP4 GPU. The benchmark test is [...]

ARM Cortex A9 vs ARM Cortex A15 – What to expect, and what’s the difference?

by: LucianMay 22, 2012

ARM has completely dominated the mobile market for more than a decade, with over 90% market share, but it wasn’t until the rise of modern smartphones that we started to witness chips more powerful than anyone could have ever imagined we’d see in phones — chips that are now even starting to threaten Intel’s dominance and their status quo computing architecture.

Starting with the ARMv7 architecture and the first Cortex CPU based on it, the A8, we already began to think of these devices as superphones or mini-computers once the 1 GHz barrier was broken. Then came the dual core Cortex A9 chips and, [...]

With Galaxy S3 rumors over, let the next Nexus rumor party begin

by: LucianMay 16, 2012

For more than half a year, we’ve had more than enough Galaxy S3 rumors. Some of them were pretty crazy, like the 1080p screen, while others were predictable (the quad core Exynos 4412 chip). Samsung delivered some of the more predictable ones, while  it failed to hit the target on others (Pentile screen), and also disappointed some people with the design and build quality. These have been some of the major flaws of all Galaxy S devices, and yet Sammy didn’t do much to address them.

So with that in mind, you should always be at least a bit skeptical about all rumors, especially the ones appearing months ahead of the supposed launch of a device. But as the [...]
