NVIDIA Tegra 3
关键字： T30SL T33The NVIDIA Tegra 3 (T30) is a quad-core processor for tablets and smartphones that was introduced at the end of 2011. It features four fast clocked Cortex A9 cores and a fifth companion core clocked at 500 MHz to save power (4-Plus-1 architecture). The 5th core is manufactured with low power transistors and running on a seperate power plane. The clock speed of the four cores can reach up to 1.6 GHz (depending on the version and core load). A single core can reach 100 MHz higher clock speeds (up to 1.7 GHz currently). There are a many different versions of the Tegra 3 SoC currently used in smartphones (AP) and tablets (T), e.g.: T30SL / T30L 1.2 / 1.3 GHz, 416 MHz GPU, 1333 MHz DDR3: Asus Transformer Pad 300, Nexus 7, Sony Xperia Tablet S AP30 / T30 / T30s 1.4 / 1.5 GHz CPU, 520 MHz GPU, 1066 MHz LPDDR2 / 1500 MHz DDR3-L: Asus Eee Pad Transformer Prime, Acer Iconia Tab A510, A700, HTC One X, Toshiba AT270, AT 300, ... T33: 1.6 / 1.7 GHz CPU, 520 MHz GPU, 1600 MHz DDR3: Asus Transformer Pad Infinity 700 AP33: 1.4 / 1.5 GHz CPU T33A: 1.6 / 1.7 GHz CPU, higher clocked GPU and memory The integrated Geforce ULP is similar to the version in the Tegra 2 and offers 4 more vertex shaders and some small improvements. A bottleneck of the SoC is the 32 Bit memory interface altough it supports up to 2 GB DDR3-1600 / DDR3L-1500 / LPDDR2-1066. The included video decoder is able to play back 1080p HD videos with a bitrate of up to 40 Mbit/s. It supports the codecs H.264, MPEG-4, DivX, WMV and VC-1 (altough you need software like the Dice Player to use the hardware acceleration). Series NVIDIA Codename Kal-El Clock Rate 1200-1600 - 1300-1700 MHz Number of Cores / Threads 4 / 4 Manufacturing Technology 40 nm Die Size 80 mm2 Features 12 core GeForce LP 64 Bit no 64 Bit support Announcement Date 11/09/2011
