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 [...]
When the Crysis FPS game came out on the PC in 2007, it pushed the boundaries of what gaming graphics should look like. The “Can it run Crysis?” catchphrase became an Internet meme, a question asked whenever a new CPU or GPU is announced.
ARM hardware has been evolving at an amazing pace, with the performance of mobile GPUs doubling every 12 months. Low-power ARM chips are very close to surpassing the current gen consoles, in terms of performance and gaming visuals. Crytek, the company behind Crysis, seems to agree that, if the next-gen PS4 and Xbox720 won’t come soon, video consoles will be surpassed by tablets as the main devices for [...]
The OpenGL ES 2.0 specification has been finalized since 2007, but we didn’t get to use it in smartphones until 2009, when the iPhone and Android phones started supporting it in hardware. It still feels like a long time for the OpenGL ES specification to be updated, though. But the wait is over, as Khronos, the group responsible for OpenGL, OpenCL, OpenVL (augmented reality) and other open standards, has finally announced that the OpenGL ES 3.0 specification has been ratified.
The OpenGL ES 3.0 specification is largely an implementation of the desktop version of OpenGL 3.3, with some other features taken from OpenGL 4.x. Compared to [...]
Although we haven’t even seen the first generation of Mali T600 series GPUs shipping, ARM is already announcing the second generation of T600 GPUs, not only for the Mali T604, but also for the GPU-compute-oriented Mali T658. These second generation GPUs are the Mali T624 (4 cores) and Mali T628 (8 cores) for the graphics-oriented chips, and Mali T678 for the GPU compute oriented product.
Why is ARM announcing such a confusing move right now? Because it seems that, while they think GPU compute will be an important part of mobile GPUs in the future, they aren’t sure just how important it will be. GPU compute hasn’t really caught on in the mainstream PC [...]
The GLBenchmark is now the standard benchmarking tool to compare mobile GPUs. We’re going to see a GLBenchmark 3.0 this fall with all the necessary tests for the new OpenGL ES 3.0 standard, but until then, we get a significantly improved GLBenchmark 2.5 version. The new version still tests only OpenGL 2.0 features, but does it in a much more aggressive way, leaving even the latest mobile GPUs struggling to achieve 15 FPS in most tests, let alone 30 FPS.
Considering that GLBenchmark 3.0 is just a few months away, and will probably arrive before any of the OpenGL ES 3.0 devices come to market, I’m surprised that the benchmark’s developers decided to [...]
We knew since last year that Samsung was working on a 2560×1600 panel for tablets. Some thought that this panel would be used for the new iPad, but it was pretty obvious Samsung would want to use it themselves as well. This is not to mention that the ratio is 16:10, which is exactly what this Android tablet has.
We’ve also heard rumors this year about a tablet that is “bigger than 10” that would have the long-awaited Exynos 5250 chip, which would contain a next-gen dual core 2 Ghz Cortex A15 CPU and a next-gen Mali T604 GPU. The Mali T604 should be at least twice as powerful as the [...]
When Qualcomm launched the new “Krait” CPU architecture, I was disappointed that it didn’t launch the new Adreno 3xx GPU architecture as well. Ever since Qualcomm bought the Adreno team and technology from AMD a few years ago, the Adreno GPUs have been at least slightly behind the competition.
The new Adreno 320 GPU that is arriving in the quad core S4 Pro SoC comes with some much needed features that should push mobile graphics forward. However, the performance of the GPU is ultimately not as good as it should’ve been, when compared to what will be available in the market by the time devices with Adreno 320 begin [...]
The Snapdragon S4 chip, based on the new Cortex A15-class Krait design, is currently the most advanced ARM processor core in the market. Along with the integrated LTE modem, the advanced design of the Krait architecture made the Snapdragon S4 very popular in US, both with manufacturers and end users.
But while the S4 is very good, it also has two big flaws. One is perhaps more marketing-related: being “just” a dual-core in a market filled with quad-core Cortex A9 chips. The second shortcoming, a real one this time, is the chip’s last-gen GPU. The Adreno 225 GPU is based on the very old Adreno 200 architecture, which is basically what [...]
Just like with the HTC One X, which had a quad core Tegra 3 version internationally, but a dual core Snapdragon S4 version in the US, because it was the only available chip with an integrated LTE modem: the Galaxy S3 came with an Exynos 4 Quad chip for all non-LTE markets, and a Snapdragon S4 for the LTE ones, including the US market.
So until now, if you were an American citizen, you couldn’t even choose the quad core version if you wanted, for the GSM networks. But that may be about to change soon, as Samsung is apparently going to launch an unlocked version of the Galaxy S3, the same i9300 model we saw on the [...]
