NVIDIA: OMAP 4470 is 50% faster than Tegra 3
Yesterday Amazon announced its new Kindle Fire HD soc based on the Texas Instruments OMAP 4470 , which claim has outperformed its competitors products based on Nvidia Tegra 3 SoC . Comment could not be left without a response from Nvidia:
It’s good to see companies continue to use a Tegra 3 as the standard to compare their products. The popular Nexus 7 showed the capabilities of the Tegra 3 processor.
You can not measure the experience that provide the user with comparisons (benchmarks) synthetic. A better way to measure it is with applications and examples of real use. Tegra 3 has shown time and again that provides a great experience to consumers in both games, as streaming video or other applications.
At other times, companies with products based on the arm Cortex-A15 architecture as Snapdragon S4 Series (based on Qualcomm’s Krait architecture), OMAP 5 Texas Instruments and Exynos 5 of Samsung, have proclaimed their superiority to Tegra 3, which architecture is based on the Cortex-A9, but very few companies with products that claim Cortex-A9 also be higher, as the SoC K3V2 of Huawei.
Tegra 3 quad-core and possess K3V2 Cortex-A9, but the latter has some additional features that allow you to outperform Tegra 3, but has omap 4470 dual-core Cortex-A) how can a dual core SoC Cortex-A9 exceeds a quad-core Cortex-A9?
The response to this we have in the eternal war between frequency vs. features vs. number of cores, and is that even Tegra 3 has four cores running at 1.3GHz (1.4GHz when three of them are at rest), OMAP 4470 runs 1.5GHz, and is accompanied by a dual channel memory controller (Tegra 3 is mono channel) and a powerful PowerVR SGX544 Imagination Technologies IGP.
Although additional frequency OMAP 4470 is insufficient to distance himself as much of Tegra 3, the memory controller dual channel performance should favor per cycle, for in other dual-channel architecture brings the performance increases of up to 20% for the CPU and to 50% for the IGP / GPU (although there is no test to give an exact figure on the ARM architecture).
Additional features of OMAP 4470 combined with the most frequently enough so that most of the synthetic test well ahead of Tegra 3, but these advantages are not only reflected in synthetic test, as also must demonstrate a better user experience in the form a higher bandwidth applications, a higher update rate of the display, and more FPS games.
In order to be very difficult to know exactly under what OMAP 4470 applications exceeds Tegra 3, but obviously there must be some cases where Tegra 3 defeats OMAP 4470, unfortunately it will not be known until they appeared more evidence showing the strengths and weaknesses of both SoC.
