Nvidia 今天面向移动互联网设备 (MID) 发布了两款全新的 Tegra 系列处理器，向"老大哥"Intel 发起挑战。

这两款处理器分别为 Tegra 600 和 Tegra 650，主要面向微型计算设备而设计。但最初，Tegra 系列产品主要面向新兴的 MID 设备。

最早提出 MID 概念的是 Intel，其 Atom 处理器也正是面向MID设备而开发。但 Intel 和 Nvidia 均承认，到目前为止，用户对 MID 的定义仍然很糊涂。 Nvidia 移动事业部总经理 Mike Rayfield 称，MID 的屏幕尺寸应在 4 英寸至 12 英寸之间，采用键盘或触摸屏设计，可接入游戏机或无线高速互联网。

据 Mike Rayfield 介绍，Tegra 处理器体积只有硬币大小，但却集 ARM 11 处理内核、图形处理单元、媒体处理器、系统内存等为一体。

Mike Rayfield 称，在不远的将来，越来越多的客户将在产品中采用 Tegra："本周末就会有厂商介绍他们的产品，但最初所有的产品将出自台湾市场，他们的反应最快。"

Mike Rayfield 还称，基于 Tegra 的 MID 设备将于圣诞期间上市，价格预计在 200 美元至 250 美元之间。对此，Insight 64 分析师 Nathan Brookwood 说："如果注重设备的整体性能、图形显示能力、以及播放高清视频内容的能力，那么 MID 是不错的选择。"

尽管 Tegra 和 Atom 均面向 MID 设备，但两种芯片的架构完全不同。Atom 基于 x86 架构，而 Tegra 则基于 ARM 处理器架构。 Intel 认为，ARM 处理器主要面向通信和手机市场，而 x86 处理器主要面向游戏和网络浏览等应用。因此，x86 处理器要优于 ARM 处理器。

但 Mike Rayfield 却并不这样认为，他说："在过去的 10 年甚至更久的时间里，ARM 处理器拥有最佳的'每毫瓦性能'。因此，这是一场挑战 ARM 强项的战斗。"而 Nathan Brookwood 认为，目前尚无法预测胜负，但这将是一场很有趣的对决。

NVIDIA TEGRA: THE HEART OF THE WORLD'S SMALLEST VISUAL COMPUTERS
SANTA CLARA, CA-JUNE 2, 2008-Today, NVIDIA brings visual computing to mobile internet devices (MID) with the launch of NVIDIA® Tegra™, a family of highly integrated computers on a chip. In addition to MIDs, the NVIDIA Tegra 650 and 600 processors will be used in a wide range of innovative platforms such as embedded PCs, web tablets and more. The NVIDIA Tegra 650 processor is the world's first computer on a chip for mobile visual computers. NVIDIA Tegra features a GPU, media processor, system memory, peripherals and a CPU all in one ultra-low power chip, smaller than a US dime (10-cent piece).

The NVIDIA Tegra 650 processor is the second product in the Tegra line, the first being the NVIDIA Tegra APX 2500 processor, which is enabling the next generation of Windows Mobile smartphones. "With the growing market demand for mobile Internet access, NVIDIA launched the APX 2500 computer-on-a-chip targeted at smartphones and handsets earlier this year. Recognizing that mobile Internet access usages will occur not just on smartphones and handsets but on compute devices as well, NVIDIA announced today their Tegra product line. Representing the first products to be targeted at the MID and portable device space, it is anticipated to bring integrated capabilities similar to the APX 2500 with NVIDIA's graphics expertise, an ARM core, HD video,and advanced power management," said Ian Lao, senior analyst at In-Stat.

This new processor features an optimized combination of an ultra-low power GeForce® GPU and an 800 MHz embedded ARM CPU, Due to their highly integrated design, NVIDIA Tegra processors achieve up to 10 times the power efficiency of existing products in battery-operated computer systems running compelling visual computing applications.

"As more consumers begin to access the mobile Internet with devices like smartphones and MIDs, device manufacturers will be challenged to create the same high-quality user experience on mobile devices that consumers currently enjoy on their desktop PCs," said Warren East, CEO, ARM. "Using advanced ARM technology and providing a ground-breaking mix of performance, power consumption and form factor, the NVIDIA Tegra mobile computer-on-a-chip addresses
this challenge more effectively than any other solution yet on the market, thereby taking a major step toward the oncoming mobile Internet revolution."

NVIDIA Tegra 650 also features:
• All-day media processing, for 130 hours audio, 30 hours HD video playback
• HD image processing for advanced digital still camera and HD camcorder functions
• Optimized hardware support for Web 2.0 applications for a true desktop-class internet
experience
• Display support for 1080p HDMI, WSXGA+ LCD and CRT, and NTSC/PAL TV-Out
• Direct support for WiFi, disk drives, keyboard, mouse, and other peripherals
• A complete Board Support Package (BSP) to enable fast times to market for Windows
Mobile-based designs

"With NVIDIA's Tegra processor line, we will continue to see impressive mobile innovations in Windows Mobile products," said Todd Warren, corporate vice president of Microsoft's mobile communication business. "Microsoft is dedicated to providing people best-in-class mobile experiences, so that people can carry a single device for work and play."
