haswell架构

Intel sent me a Haswell Developer Prototype Ultrabook to review a little over a month ago. In order to effectively review this, given my experience, I need to separate the Haswell Chipset and Processor from this specific machine that they send folks to review.

英特尔在一个多月前给我发了一台Haswell开发原型超级本进行审查。 为了有效地对此进行审查，根据我的经验，我需要将Haswell芯片组和处理器与他们派遣人员进行审查的这台特定机器分开。

I did not receive a very good unit - definitely not one ready for production.

我没有收到一个很好的单元-绝对没有一个可以投入生产的单元。

Now, to be fair, it's marked as an "Intel Software Development Platform" prototype. This is not a machine that will ever be built, and it's also (they tell me) still getting drivers developed. It's a fairly regular looking gunmetal Ultrabook with no markings other than the Intel and Ultrabook logos. It's a lot like my Lenovo X1 Carbon Touch except it has a 1080p (vs. 900) screen and it's a Haswell. This review platform is a new i5 vs. last year's i7 in my X1.

现在，公平地说，它被标记为“英特尔软件开发平台”原型。 这不是一台将要制造的机器，而且(他们告诉我)仍然在开发驱动程序。 这是一款外观相当普通的枪色Ultrabook，除了Intel和Ultrabook徽标外没有其他标记。 它非常类似于我的Lenovo X1 Carbon Touch，但它具有1080p(相对于900)屏幕，并且是Haswell。 这个评论平台是我的X1中与去年的i7相比新的i5。

Last year I looked at the 3rd gen "Ivy Bridge" ultrabooks and was impressed. So impressed that I eventually bought a Lenovo X1 Carbon Touch:

去年，我看了第三代“ Ivy Bridge”超极本，并对此印象深刻。 令我印象深刻的是，我最终购买了联想X1 Carbon Touch：

• Initial Impressions of the 3rd Generation Ivy Bridge Intel Ultrabook Reference Hardware for Developers on Windows 8 (with video)

  Windows 8上面向开发人员的第三代Ivy Bridge英特尔超极本参考硬件的初步印象(带视频)

• Intel Ultrabook hardware prototype - Windows 8 and the Sensor Platform

  英特尔Ultrabook硬件原型-Windows 8和传感器平台

• My next PC will be an Ultrabook

  我的下一台PC将是一本Ultrabook

• Review: The Lenovo X1 Carbon Touch is my new laptop

  评论：联想X1 Carbon Touch是我的新笔记本电脑

第一：此特定的Haswell参考平台设备(First: This particular Haswell Reference Platform device)

This year's Haswell review unit has been nothing but trouble for me. Such trouble, in fact, that they've sent me THREE separate laptops as the first two both were unacceptable for different reasons. The first laptop had the SSD fail completely within a week. The second laptop had a bad Synaptics touchpad where only the right side worked. While the third one is workable, it turns off randomly, doesn't want to support standby/sleep and has a wonky keyboard with an unreliable "A" key.

今年的Haswell审查部门对我来说不过是麻烦。 实际上，这样的麻烦使他们给我寄了三台单独的笔记本电脑，因为前两者由于不同的原因而无法接受。 第一台笔记本电脑在一周内就使SSD完全失效。 第二台笔记本电脑的Synaptics触摸板不好，只有右侧可以使用。 尽管第三个键盘是可行的，但它会随机关闭，不希望支持待机/睡眠，并且键盘上的键盘不稳定，并且键的“ A”键不可靠。

Again, they're reference review laptops, but let's just say they aren't production quality Lenovo X1s or MacBook Airs. To be very frank, these not-ready review/prototype laptops and the experience I have had with them actively do the product a disservice. I'm sure Haswell as a platform is lovely and I would like to see how a Haswell-enabled system makes my life as a developer better. However, in order to do that I expect the mouse to work, the Bluetooth to be reliable and for the screen to stop rotating to the left without warning (even though I keep setting auto-rotate off.)

同样，它们是参考评测笔记本电脑，但我们只能说它们不是生产质量的联想X1s或MacBook Air。 坦率地说，这些尚未准备就绪的评测/原型笔记本电脑以及我对它们的积极使用经验对产品造成了损害。 我确信Haswell平台是一个很好的平台，我想看看支持Haswell的系统如何使我作为开发人员的生活变得更好。 但是，为了做到这一点，我希望鼠标能够工作，蓝牙必须可靠，并且屏幕可以在不发出警告的情况下停止向左旋转(即使我一直设置为自动旋转关闭)。

With the Ivy Bridge reference platform I saw constant and consistent improvements in system behavior with regularly updated drivers. With this Haswell reference platform I have seen just one driver drop, been told to not upgrade to Windows 8.1, and only updated the BIOs once. I have no idea if this device will ever become usable in the future because I have no communication or indication when new drivers are coming.

通过Ivy Bridge参考平台，我看到了定期更新的驱动程序对系统行为的持续不断的改进。 使用此Haswell参考平台，我只看到一个驱动程序下降，被告知不要升级到Windows 8.1，并且仅更新一次BIO。 我不知道该设备将来是否会可用，因为我没有交流或显示新驱动程序何时到来。

第二：每天使用Haswell ...强大的功能 (Second: Using Haswell every day...and the power promise)

Ok, now that that's over. I've been using this every day running Windows 8 and have presented at two conferences with this device. I've run both VS2012 and VS2013 on it.

好的，现在结束了。 我每天都在运行Windows 8并使用此设备，并且在两次会议上都使用此设备进行了介绍。 我已经在上面运行了VS2012和VS2013。

Even though Windows 8.1 does away with the WEI (Windows Experience Index) and I think that's a shame as it's a totally useful and built-in way to get a sense of how a computer will perform, I'm running Windows 8 on this Haswell machine and can still run it.

尽管Windows 8.1取消了WEI(Windows体验指数)，但我认为这很遗憾，因为它是一种完全有用的内置方法，可以了解计算机的性能，但我在此Haswell上运行Windows 8机器，并且仍然可以运行它。

Surprising new device gets almost an identical WEI as my Lenovo X1 differing significantly only in memory ops/sec. I've heard this elsewhere that an i5 Haswell can perform as well as an Ivy Bridge i7 *and* with a much improved power profile. Haswell isn't (to me) about pure speed, it's about speed, power, and lightness.

令人惊讶的是，新设备的WEI与我的Lenovo X1几乎相同，仅在内存操作/秒方面有显着差异。 我在其他地方听说过，i5 Haswell的性能可以与Ivy Bridge i7 *和*媲美，并且功率曲线得到了大大改善。 Haswell并不是(对我而言)纯粹的速度，而是关于速度，功率和亮度。

This is very light laptop. As my second laptop around 3lbs it's cemented my conviction that I'll never own a big heavy luggable laptop again. There's just no reason for a 10 pound device anymore.

这是非常轻便的笔记本电脑。 当我的第二台笔记本电脑重约3磅时，我坚信我永远不会再拥有一台笨重的大型笔记本电脑。 只是没有理由再使用10磅重的设备了。

Performance, however, does seem dramatically different when on batteries. It appears to be extremely aggressive trying to saving power. This is definitely a laptop where changing Power Profiles makes a huge difference.

但是，使用电池时，性能确实有很大不同。 试图节省电量似乎非常激进。 绝对是一台笔记本电脑，在其中更改电源配置文件会产生巨大的变化。

The greatest difference in how long this device will last has been screen brightness. When I'm on Power saver on the lowest brightness, I could get a full work day out of this device. However, the lowest brightness is just not feasible. I got between 6 and 7 hours with brightness at about one-third.

该设备可使用多长时间的最大区别在于屏幕亮度。 当我以最低的亮度打开节电器时，可以从该设备上花费整整一天的时间。 然而，最低的亮度只是不可行的。 我花了6到7个小时，亮度只有三分之一。

Switching to the Balanced Profile with the brightness at the level where Windows warns you it might be a problem, I got about 5 to 6 hours of typing.

切换到平衡配置文件时，亮度达到Windows警告您可能会出现问题的水平，我大约需要5到6个小时的打字时间。

It's getting to around half-battery where you start getting uncomfortable and wondering if you're going to make it. Changing brightness and profile can get you an easy extra hour on Haswell, where it's just been a matter of 15-20 minutes (in my experience) on other devices.

电池快要用完一半了，您开始不舒服，想知道是否要制造它。 更改亮度和配置文件可以使您在Haswell上轻松多花一个小时，而在其他设备上，这仅需15-20分钟(根据我的经验)。

Does Haswell deliver the all-day battery laptop?

Haswell是否提供全天候电池笔记本电脑？

• Yes, if you write prose for a living. 是的，如果您以散文为生。
• Yes, if you aren't running at full brightness. 是的，如果您没有以全亮度​​运行。
• Yes, if you work in SSH or VIM and a remote Linode machine is actually doing the work while your Haswell waits. 是的，如果您使用SSH或VIM，并且在Haswell等待时，一台远程Linode计算机实际上正在执行该工作。
• No, if you're writing and compiling a 3D game locally. 不，如果您要在本地编写和编译3D游戏。
• No, if you're playing Steam and running TorchLight II.不，如果您正在玩Steam并运行TorchLight II。

Should you get a Haswell machine? Absolutely. If you're in the market for a machine and there's a Haswell version of your favorite coming soon, wait. You'll get the same speed and better battery life. Maybe not all day, but 50% more than before. I'm looking forward to the refreshed Lenovo T and X series to have Haswell on board.

你应该买一台Haswell机器吗？ 绝对。 如果您打算购买一台机器，并且即将推出您喜欢的Haswell版本，请稍候。 您将获得相同的速度和更长的电池寿命。 也许不是整天，但比以前多了50％。 我期待更新的Lenovo T和X系列加入Haswell。

All day power? My expectations perhaps aren't reasonable. Haswell and aggressive power management is the future, no doubt. I think, however, that it will be a combination of this plus improvements in battery density that will finally give me a 24 hour device (or 8 hours working hard at full brightness).

一整天没电？ 我的期望也许不合理。 毫无疑问，Haswell和积极的电源管理将是未来。 但是，我认为这将是这些结合以及电池密度提高的结合，最终将为我提供24小时的设备(或8小时的全亮度工作)。

ASIDE: From a reviewer perspective, while it's always fun to answer the "what laptop is that?" question with "it's an Intel prototype," the folks at Intel should, when possible, loan reviewers machines that are closer to production that don't have all these driver quirks and hardware quality issues. Why? Well, I really value the opportunity to to review new and prototype hardware, the question always comes up...am I reviewing the keyboard and mouse and screen or am I reviewing the chipset and processor. Of course, there's drivers to hold it all together. This review unit has a loud fan, and iffy construction. But, it has great speed and I didn't think about memory once even though I was running only 4 gigs. I was able to run multiple instances of VS, Outlook and many browsers without even a thought. Even two Virtual Machines and it still felt fast.

ASIDE：从审阅者的角度来看，回答“那是什么笔记本电脑”总是很有趣。 对于“这是Intel原型”的问题，Intel的人们应该在可能的情况下，借贷审查员机器，这些机器更接近生产环境，并且没有所有这些驱动程序怪癖和硬件质量问题。 为什么？ 好吧，我真的很珍惜审查新硬件和原型硬件的机会，这个问题总是会出现……我正在审查键盘，鼠标和屏幕，还是正在审查芯片组和处理器。 当然，有驱动程序可以将所有内容组合在一起。 该审核单元风扇很大，结构也很杂乱。 但是，它的速度非常快，即使我只运行了4个演出，我也没有想过内存。 我什至无需考虑就能运行VS，Outlook和许多浏览器的多个实例。 即使是两个虚拟机，它仍然感觉很快。

I want to get my hands on a device like a Lenovo Yoga 2 Pro or a Thinkpad Yoga. These Haswell devices are going to rock. I have extremely high hopes, but rest assured, your next machine is a Haswell.

我想动手使用Lenovo Yoga 2 Pro或Thinkpad Yoga之类的设备。 这些Haswell设备将会动摇。 我寄予厚望，但请放心，您的下一台机器是Haswell。

Disclosure of Material Connection: Intel sent me this Haswell Ultrabook in the hope that I would review it on my blog. Regardless, I only recommend products or services I would use and think you would find useful. This opinions are mine and mine alone as is this entire post. I am disclosing this in accordance with the Federal Trade Commission’s 16 CFR, Part 255: Guides Concerning the Use of Endorsements and Testimonials in Advertising.

重大联系的披露：英特尔向我发送了此Haswell Ultrabook，希望我可以在我的博客中对其进行审查。 无论如何，我只推荐我会使用的产品或服务，并认为您会觉得有用。 这是我的观点，也是整个职位的观点。 我根据联邦贸易委员会的16 CFR第255部分：有关在广告中使用背书和证明书的指南进行披露。
