看了下，GPU继续用POWERVR,跟PSP2一样是多核MP，Cortex-A15比同频的A9快50%,OMAP5平台计算性能是OMAP4的3倍，GPU是OMAP4的5倍，但比上OMAP 4平台还要少60%功耗，基本上是多核化设计的，包括CPU,GPU,DSP...
TI预计下半年出sample，而终端产品要明年下半年...

Highest performance, lowest power...yet again
The 28 nanometer OMAP 5 applications processors carry on the OMAP family tradition of delivering significant increases in performance and functionality, while lowering power consumption compared to their predecessors. Specifically, they offer up to 3x processing performance and five-fold 3D graphics improvement, yet provide a nearly 60 percent average power reduction compared to a sample user experience on the OMAP 4 platform. Additionally, the OMAP 5 platform's software is designed for maximum reuse to ease migration from the OMAP 4 platform.
"The next decade will bring a revolution in mobile computing, as devices continue to converge, attempting to become one single device that meets all of our computing, entertainment, and complex day-to-day needs and interests. However, the bridge to true mobile computing enablement was missing until today. The OMAP 5 platform will be at the heart of driving the mobile computing revolution by delivering the highest computing, graphics and multimedia performance possible within the low power budget required by mobile form factors," said Remi El-Ouazzane, vice president, OMAP platform business unit, TI.
Industry's best all-around applications processor platform
The OMAP 5 platform sports an impressive list of features and benefits supporting everything from open source platforms to complementary TI technologies, including:


Features	Benefit *
Two ARM Cortex-A15 cores, up to 2 GHz each	3x higher performance to deliver the promise of mobile computing
Two ARM Cortex-M4 cores	Low-power offload and real-time responsiveness
Multi-core 3D graphics and dedicated 2D graphics	5x higher graphics performance; accelerated and more responsive user interfaces
Multi-core imaging and vision processing unit	Next-generation computational photography experiences – face recognition, object recognition and text recognition
Multi-core IVA HD video engine	1080p60 HD video and high performance, low bit rate video teleconferencing
Advanced, multi-pipeline display sub-system	Supports multiple video/graphics sources for composition
Can support four simultaneous displays	Supports three high-resolution LCD displays (up to QSXGA) and HDMI 1.4a 3D display
High performance, multi-channel DRAM and efficient 2D memory support	Supports advanced use cases with multiple ARM cores and multimedia operation; provides better user experiences without lag or quality degradation
TI M-Shield™ mobile security technology with enhanced cryptography support	End-to-end device and content protection
New, high-speed interfaces	Supports USB 3.0 OTG, SATA 2.0, SDXC flash memory and MIPI® CSI-3, UniPort-M and LLI interfaces to support higher Wi-Fi and 4G network and HD content data rates
Optimized audio, power and battery management platform solutions	Complementary TI devices for an optimized OMAP 5 platform solution
Next-generation connectivity technologies	HD wireless video streaming, wireless display, mobile payments and enhanced location-based services
*Comparative statements compare OMAP 5 platform to OMAP4430 applications processor.

Strengthening the OMAP 5 platform's value, TI leverages its open source community involvement to benefit customer product development. Early extensive work in community projects translates to a significant quality and schedule advantage for device manufacturers, including power, memory and performance optimization. Additionally, TI's pre-integrated software packages for popular Linux-based distributions help manufacturers achieve maximum system-level performance while driving a faster time-to-market.
Availability
TI's OMAP 5 platform is expected to sample in the second half of 2011, with devices on the market in the second half of 2012. The OMAP5430 processor is offered in a 14x14mm Package-on-Package (PoP) with LPDDR2 memory support. The OMAP5432 processor is offered in a 17x17mm BGA package with DDR3/DDR3L memory support.

-------如果所言不虚，那些吵着多核ARM cpu 要耗电很大的想当然言论很快就躲起来无法再出来了。

NV年底也有样片，估计还是领先Ti。只不过不像Tegra2领先的时间那么长。Tegra2是去年1月的CES上发布的。
这Ti A9双核还没有正规上市，下半年就有A15的了？这贴估计要被挖的。

德州仪器OMAP平台部门总经理雷米·艾尔-奥扎尼(Remi El-Ouazzane)表示，OMAP 5基于ARM Cortex A-15架构打造，这也是该公司在该市场率先所为，从而在行业中占据先机。OMAP 5拥有双核A-15，2GHz频率，比其前一代OMAP 4快三倍，耗能却低60%。

2G，这么高的频率；怎么可能还低功耗的？工艺大牛Intel也办不到呀！频率提升了一倍以上，加了很多的性能特性，功耗还降低６０％。这饼画得。。。Ti就要毁在这OMAP平台部门总经理雷米·艾尔-奥扎尼(Remi El-Ouazzane)的手上了。

德州仪器今天展示了其最先进的用于手机和平板的处理器TI OMAP 5，它基于ARM Cortex A15架构打造，2GHz频率傲视群雄，比之前的双核A9方案快50%，OMAP 4单核心方案快60%。

难不成这TI的双核A9方案只比自家的单核A8快：1.6/1.5 -1 = 6%.
这黑莓平板性能悲剧的。。。

还是那个观点，移动cpu专门以节能为特点的，平常待机应该可以关闭多核，就留一个核心在低频率运行等待唤醒即可。这样的情况下待机功耗多核跟单核没有多大区别；而在工作的时候，多核一起把同一工作的执行时间减少很多，让cpu更快完成，然后处于待机节能状态，多核的确有可能比单核要节能。

明年下半年……
今年年底4核A9的NGP就开始铺货了啊师傅，照您这个算法NGP的CPU比同频的OMAP5还快33%（虽是A9但多俩核）。
A9和Eager（A15）都是OOO的，intel估计在嵌入式这一块很难搞赢。

即将上市的的RIM Playbook就是用OMAP 4平台，过几天的MWC2011也许NOKIA会公布MEEGO系统的OMAP4平台手机.
其实现在的双核A9的性能已经很梦幻了
RIM Playbook，多任务够强悍的

补充一下GPU是去年中发布的SGX544-MPX，即然是MP哪肯定不会是单核,而nvidia tegra 3宣称图形只比tegra 2快3倍..
，相比TI的5倍速图形而言提升没有优势。

Multi-Imagination Technologies' POWERVR™ SGX544-MPx graphics core

Greater than 5x performance increase versus previous generation
Compelling 3D graphics interfaces
Supports large screen sizes at higher frames per second while still consuming less power than previous cores
Supports all the major APIs, including: OpenGL® ES v2.0, OpenGL® ES v1.1, OpenCL v1.1, OpenVG v1.1 and EGL v1.3

nv官方就有与SGX540基准性能比较，因为这里是显卡版面，所以才着重讨论了下未来移动GPU发展趋势而已

那是工艺进步带来的，高频多核必然高能耗毫无疑问

ARM SOC 市场看来竞争很激烈，谁也不能intel那样拉开竞争对手一大截。

几乎都从ARM拿IP授权，ARM就是它所在市场的Intel。

平板市场不可能是一家独大，必定是百家争鸣。只有良性竞争才能使市场得以活力。

tegra2图形部分的最大优势是flash矢量硬件加速，这个目前只有NV能做的到

作者: goodayoo 时间: 2011-2-9 21:52
可怜我现在还用着MOTO的XT701，CPU只是OMAP的3430，现在5系列都出来了。
