cortex A9 vs Tegra 3. how do they compare ?
the cortex a9 runs at 2.5 DIMPS per mhz where as the S3 scorpion processors run at 2.1 DIMPS per mhz but the tegra 3 im cluless. My question is what is better between tegra 3 and A9 intearms of processing power, the ability to overclock and the power usage. though I think the tegra 3 can hit 2.5 DIMPS just like the A9.
I wonder how the A5 chip compare against this ?
What are your thoughts on this ?
here's an article I found on the net:
If you've been following the main smart phone forum then you've likely seen the CPU thread. While it is heavily Android-centric due to the large proliferation of Android devices, that isn't the intent of that thread. This thread, rather, will go into more detail for Android specifically. I will highly key milestones in Android's evolution. 2008: In 2008, we saw the T-Mobile G1 (HTC Dream) launch as the first Android phone. It would be run Android 1.0 and be the first to be upgraded to 1.1, 1.5, and 1.6. The G1 featured a Qualcomm MSM7201A SOC running an ARM11 CPU at 528mhz. This CPU put out 660 DMIPS, which was near unprecedented at that time. 2009: the Motorola Droid (Milestone) was the first serious Android device. It launched with version 2.0, and using the TI OMAP 3430 clocked at 550mhz output 1100 DMIPS, nearly doubly the performance of the G1. 2010: Android exploded in 2010. However, there was only one truly milestone release, and that was the Google Nexus One. Made by HTC, the Google Nexus One used a Qualcomm Snapdragon S1, which at 1ghz, output 2100 DMIPS. This was nearly double that of the Droid which had releases only 2 months early. This chipset was so powerful that it wasn't beaten until near the end of the year (TI OMAP 3630, 2400 DMIPS), and was even uses as the basis for all Windows Phone 7 devices in 2010. 2011: If 2010 was the Android explosion, then 2011 was the technical revolution. The first major milestone was the Motorola Atrix, which uses the Tegra 2 SOC at 1ghz. This SOC put out 5000 DMIPS, more than doubling the performance of the Nexus One. HTC then released their Sensation, which uses the 1.2ghz Snapdragon S3. This SOC put out 5040 DMIPS, providing OEMs a cheaper alternative to Tegra 2 that also included the radio built-in, while still providing comparable performance. The next milestone was the Samsung Galaxy S2. Using the Exynos SOC featuring an ARM Cortex A9 CPU clocked at 1.2ghz, this phone put out an impressive 6000 DMIPS. This was released within a month of the sensation and 3 months of the Atrix. Late the party as always was Texas Instruments with their OMAP 4 series of SOCs. The Droid 3 released several months after the Galaxy S2 using the OMAP 4430 at 1ghz, it was about as powerful as the Tegra 2 outputting 5000 DMIPS. While it was nothing special, it did preclude the eventual release of the OMAP 4460. Clocked at 1.2ghz and used in the Galaxy Nexus, this device put out 6000 DMIPS just like the Galaxy S2. It was also the flagship phone to introduce Android 4.0.
