英特尔宣称它最新的平板芯片优于英伟达的Tegra 3且耗能更低。另一个移动前端消息，这个X86架构巨头将在消费者电子展上展示功耗低于10W的Haswell 超极本。
Insight64首席市场观察员Nathan Brookwood称，英特尔设计的平板电脑双核芯片CloverTrail，在跑某些任务时，耗能不及Tegra 3的一半。尤其是该芯片的图像处理模块耗能相比Tegra 3 也低很多。
Intel将一个Windows 8的平板和一个Windows RT的微软Surface平板作了对比，得出的这个结论。其中前者用的是Clover Trail处理器而后者用的是Tegra 3.
Intel将于2013年下半年推出凌动（Atom）下一代处理器Bay Trail，同时推出一个全新的22nm制程的PC处理器 Haswell，Haswell将能兼容各种系统包括超级本。
不过，英特尔面临的问题是它们不支持LTE，所以它们在美国的市场上获胜的希望渺茫而只能转战亚洲和欧洲。（元器件交易网刘光明 摘译）

Intel claims latest tablet SoC beats Nvidia Tegra 3
SAN JOSE, Calif. – Intel claimed its latest tablet SoC outperforms the Nvidia Tegra 3 while consuming less power. On another mobile front, the x86 giant will show Haswell Ultrabooks at the Consumer Electronics Show and discuss a sub-10W variant.
Intel’s Clover Trail, a dual-core Atom SoC for tablets, consumes as much as a half a watt less that Tegra 3 on some tasks, Intel told a group of analysts recently. In particular, the Imagination Technologies graphics block on Clover Trail eats less energy than the rival Nvidia block, the company said.
“The tablet performance is as good with Clover Trail as with ARM SoCs if not better and now the surprising thing is they are using less power,” said Nathan Brookwood, principal of market watcher Insight64 (Saratoga, Calif.). “I’ve always been a little critical of that Atom core because I think they went a little too far in emphasizing power savings, but even so Clover Trial is beating Tegra 3."
Intel compared a Windows 8 tablet using Clover Trail with a Microsoft Surface tablet running Windows RT on Tegra 3. The systems were hooked up to meters measuring consumption on the processors’ power rails on a variety of jobs.
The Nvidia chip uses four main and one helper core. Brookwood said Windows RT does not use the helper core as extensively as Android. Intel did not show Clover Trail’s performance running Android.
In the second half of 2013, Intel will roll out Bay Trail which is expected to use the first out-of-order Atom cores to bolster performance. It will also roll out Haswell, a new 22-nm PC processor geared for a variety of systems including ultrabooks.
Intel “hasn’t given up on Ultrabooks by any means,” despite sluggish market uptake to date, said Brookwood.
“They are convinced ultrabooks represent a journey,” Brookwood said. “They haven’t been able to quite deliver all the features and form factors they wanted to yet, but they think Haswell will give them the muscle they need” and better than all-day battery life, he added.
Intel is expected to show at CES a reference design using a Haswell chip that consumes less than 10W and fits into an Ultrabook as thin as an Apple iPad.
Separately, Intel demoed its Medfield chip running in Android smartphones, outperforming Qualcomm and Nvidia chips in some cases while having similar battery life. “The problem Intel faces is they have no hope of the U.S. market due to their lack of LTE support--that forces them to focus just on Asia and Europe,” he said.
