年中升级款,三星更新13寸Series

飞高了一点点?是多高?半个增雉尾那么高!主要就是跟 MB、MBP 一样接纳了搭载 NVIDIA 9400M 显示芯片的芯片组,然后多了 120GB 传统硬盘、128GB SSD 等选项,CPU 频率目前则有 1.6、1.86 GHz 两种可选(原先最快 1.8GHz),L2 高速缓存为 6MB(看来应该是真 45nm 了!降温吧!)屏幕输出也从 microDVI 改成 mini DisplayPort,基本款还是在 1,799 美元,然后高阶版(1.86GHz CPU、128GB SSD)2,499 美元,但是要等到十一月。[原文连结]

全世界的苹果爱用者有好东西啦;先从上图的 Magic Trackpad 讲起,这小家伙一如先前消息,是片通过蓝牙连接的多点触控版,尺寸上约为 MacBooks 上面多点触控版的 1.8 倍,支持到四指多点触控(三指切换网页前、后页切换,四指切换 expose / 桌面,感谢读者 Irvin 提醒),吃两颗 AA 电池,售价 69 美元(香港售价 518 港币、24 小时内出货),其它细节,客位可以参考一下官网介绍页面。再来是更新版的 iMac,21.5" 采用 Core i3 处理器、频率有 3.06GHz / 3.2 GHz 可选购,27 寸部份,则有频率 3.2GHz 的 Core i3 处理器,以及 2.8GHz 的 Core i5处理器,四台基本款规格简列如下。

For many years, I’ve been testing virtual private servers for my business. you might have heard of Amazon ECS, Microsoft Azure, or Google Cloud platforms. They are giant players of the world with pretty good service and stability, but they are so expensive for individual developers and small business.

显然,9系的出现就是为了争夺苹果AIR的客源,而11寸的推出也是有针对性的,加入了高端处理器Core i7 ,提供了256GB SSD硬盘 (从128GB容量升级),高端版本可以配置6GB 的RAM 内存,2款11寸的8月份加入战局,提供了 Core i3 处理器供选择,64GB SSD,以及2GB内存,这个9系本本的卖点包括了英特尔智能TurboBoost技术2.0,高亮的LED屏幕,亮度高达400nits,拥有16M彩显等,跳转有详细的规格和相应售价,中国地区的11寸还没有加入进来。

  • 最低端的 21.5" iMac 采 LED 背光、屏幕分辨率 1,920 x 1,080,采用频率 3.06GHz 的 Core i3 CPU,内置 4GB DDR3 RAM,显卡为ATI Radeon HD 4670(内置 256MB VRAM),硬盘 500GB;其它规格部份(以下都一样就不提了)内置 8 倍速吸入式 SuperDrive、支持 Mini DisplayPort、AirPort Extreme 802.11n、Bluetooth 2.1 EDR 以及 iSight,I/O 方面,以太网络接端口、USB 2.0 x 4、FireWire 800 x 1,随机附赠无线键盘、Magic Mouse,售价人民币 9,598,『预计』四星期内出货。

I’ve tested many vps providers, ramnode, bandwagonhost, oneasiahost, sugarhosts, digitalocean, linode, and Vultr etc. some of them are rubbish, sometimes they allure you with lowest vps price and exciting server package, but in the end you have high chance to lose all your data.

8月份上市的两款规格和价格为:-NP900X1B-A02US,1.3GHz Core i3-2357M CPU,2GB内存,64GB SSD硬盘(零售价格1049美元)-NP900X1B-A01US,1.3GHz Core i3-2357M CPU,4GB内存,128GB SSD硬盘(零售价格1249美元)三款现在就可以购买到的9系笔记本的具体规格与价格如下:-NP900X3A-B01US,1.6GHz Core i5-2467M CPU,4GB内存,128GB SSD硬盘(零售价格1349美元)-NP900X3A-B02US,1.6GHz Core i5-2467M CPU,4GB内存,256GB SSD硬盘(零售价格1649美元)-NP900X3A-A05US,1.5GHz Core i7-2617M CPU,6GB内存,256GB SSD硬盘(零售价格2049美元)

另外香港方面,上面四款的售价分别为 9,188 / 11,488 / 12,988 / 15,488 港币,官网写 24 小时内出货;另外包括 Mac Pro、ACD 都有新款推出,要点整理于跳转后。

but some of them provide versatile vps with reasonable price. I’ve been using Vultr, Digitalocean and Linode since the first day they stepped into vps industry. I still remember when Vultr announced their opening many years ago, you deposit 100 dollars, they give you 100 dollars in return, so you get $200 in your account. that’s the old golden days.

图片 1Mac Pro 的部份,这次除了 CPU 升级、全线显卡升级外,还多了 12 核心的版本;基本款 CPU 为一颗频率 2.8GHz 的四核心 Intel Xeon "Nehalem",显卡基本款大家都一样,为 ATI Radeon HD 5770(1GB GDDR5 VRAM,Mini DisplayPort x 2、dual-link DVI x 1),起标价 2,499 美元;八核心的版本,CPU 为两颗四核心、频率 2.4GHz 的 Intel Xeon "Westmere" 处理器,售价 3,499 美元;12 核心的部份,处理器为两颗六核心、频率 2.66GHz 的 Intel Xeon "Westmere" 处理器,基本价为 4,999 美元。客制化升级的选项方面,可改用 HD 5870(内置 1GB VRAM),硬盘可以杀到 4TB HDD / 4 颗 512GB 的 SSD 数组,内存可以扩充到 32GB RAM;正式上市时间预计是八月份。图片 2再来则是 27" Apple Cinema Display,LED 背光、分辨率 2560 x 1440,支持 16:9 显示,内置 iSight,USB 槽 x 3,以及三头龙 MagSafe 接线(USB、含音源输入的 Mini DisplayPort、MagSafe 充电)来方便 MacBooks 的连接使用,售价部份为 999 美元。图片 3最后则是水果牌 AA 电池充电器,支持无线键盘、Magic Mouse、Magic Trackpad 等无线产品,单卖价则为 29 美元,还送六颗 AA 充电电池。

in this article, you will find some company background of each vps provider, then we will discuss what cpu models they use and CPU test results.

Linodewas founded in 2003, It provides robust servers and is private owned by its founders and employees. Linode uses Xen as platform but changed to KVM two years ago. due to growing competitors, Linode doubled vps ram and bandwidth but kept average price. Payment methods also upgraded. You can buy Linode with either credit card or Paypal.

Digitaloceanwas founded in 2011 and is sponsored by venture capitalists from USA. they provide vps mostly located in USA and Europe. all vps equipped with full KVM virtualization and SSD. digitalocean calls vps as droplet on their platform. Bulding a vps from Digitalocean is pretty fast,usually it takes 15 seconds.

Vultrstarted in 2014 as a child brand of Choopa LLC. so if you check vultr server IP, you get results showing Choopa LLC. all vps built with KVM virtualization technology. Vultr is a young competitor full of ambition. it has cheap price but with very powerful servers. Vultr also has the most data centers all over the world.

CPU model

what cpu models are in use by vultr, linode and digitalocean? let’s take a look:

Edit

CPUSingle Thread Passmark

VultrIntel Xeon E5-2620 v31710

LinodeIntel(R) Xeon(R) CPU E5-2680 v2 @ 2.80GHz1758

DigitaloceanIntel(R) Xeon(R) CPU E5-2650L v3 @ 1.80GHz1344

How powerful is it? Let’s run CPU benchmark:

sysbench –test=cpu –cpu-max-prime=20000 –num-threads=1 run

It shows clearly that Vultr has beaten the other two competitors with shortest time needed.

Of course this benchmark does not stand up for 100% the realtime situation,but it at least gives us closer look into these vps providers.

If your projects are CPU oriented, I really recommendVultrthanDigitalocean.Linodeis also good choice.
