Nvidia has just dropped a nugget of gold at our doorstep – and it contains a bit of a bombshell folks. It turns out that Project Kal-El, also known as “Tegra 3″ is not actual a Quad Core SoC after all – it’s a Quintuple Core SoC.
Not disclosed publicly previously, is a trick that Nvidia has been keeping up their sleeve — until today. Employing a novel process dubbed Variable Symmetric Multiprocessing (vSMP) technology – NVIDIA’s Project Kal-El SoC includes a fifth “Companion Core” created using a special low power silicon process that executes select tasks like music playback, video playback, reading loaded web pages, RSS’ reading, and accomplishes this all at extremely low frequencies for even further power savings.
Even though there’s a fifth “Companion” core, there’s still four main A9 Cortex cores standing by, hungry for more. These four main cores have been created using a standard silicon manufacturing process, and are designed to reach significantly higher frequencies. Nividia claims that they can do this while still consuming less power than their dual core counterparts, and for many tasks, so long as the software has been optimized. Additionally, all five CPU cores are ARM Cortex A9 CPUs, and are controlled based on how much processing is thrown their way, via a process Nvidia dubs “aggressive power gating”.
According to Nvidia, the benefits of quad-core (multi-core, quintuple core, etc), are as follows:
More cores are simply better folks, so long as the software is optimized to take advantage of them. Quad core CPU-based processors – mobile or not – deliver significantly higher levels of performance for the type of applications below, and deliver a compelling performance advantage over their single and even dual core set-ups. Examples include:
Think about how you use your Android device. It’s not uncommon to have it streaming music, while you read a webpage with multiple tabs open, email and social networks syncing, and perhaps even more. Under this sort of workload, it’s no wonder why the single- core Android champs of yesteryear, like the HTC Thunderbolt, ran dry in a few short hours. Under such a heavy multitasking load, a single core CPU not only has to work a high frequency continuously, it also results in significantly higher power consumption which leads to a device running dry in no time.
With quad core CPU’s on mobile devices, future versions of Android will be able to dynamically allocate workloads across different cores, all while doing this at lower frequencies and with no compromise in the user experience. Simply put – they’re going to rock your world.
Bottom line – quad core CPU’s provide significant processing power for game, app, and web developers to take advantage of. We are finally achieving a reality where our mobile devices will have a power envelope that holds parity with some of the more powerful devices of today – but in a mobile device. Multi-Core CPU Architecture will enable mobile devices to further push the performance envelop to levels never before anticipated, and allow application and game developers to create amazing new mobile experiences, all while extending battery life for the ways most people use their devices. Of course remember folks – very few people have seen how Tegra 3 actually performs in the real world. That being said, I have no doubt to the validity of Nvidia’s claims – they’re playing for keeps, and are really taking this mobile computing stuff seriously.
And let’s not forget about the power savings. Nvidia reckons that we’ll see a significant decrease in power use, which equals better battery life, and based off the information we’ve mentioned above that we derived from their whitepapers, we’re inclined to agree with them.
Additionally, there’s the newly designed GPU, with 12 cores all on its own. Said to offer three-times the performance of Tegra 2, it not only should provide amazing performance on current versions of Android, but will also really take mobile computing to new heights once developers get on the bandwagon, with great stuff like dynamic lighting and real-time physics rendering and dynamic lighting.
Any thoughts? Want to know when these processors are coming? Sooner than you think. Viva the quad – no wait, quintuple core revolution!
