尽管它们已经问世十多年了，但英特尔的酷睿(Core)系列酷睿(Core)i7、酷睿(Core)i5 和酷睿(Core)i3 处理器仍然感觉相对年轻。在这里，我们将回顾处理器，解释它们背后的技术，看看英特尔的理念，并帮助您决定购买哪种处理器。
与其走传统的处理器对比路线，向你展示一堆基准测试、游戏性能规格等，本次评测将重点解释英特尔核心CPU阵容的“核心”，其中还包括新的酷睿(Core)i9 系列。
尽管基准测试对铁杆游戏玩家很有用，但它们对普通计算机用户几乎没有用处。本指南将帮助您挑选一台具有满足您需求的良好处理器的计算机，而无需了解“ 3DMark ”是什么。
您可能想知道的第一件事是现在是否是购买配备英特尔酷睿(Intel Core)处理器的 PC 的好时机？任何人去买东西并在第二天发现公司刚刚发布了更好的模型，这有点令人沮丧。
答案几乎总是肯定的，现在是购买配备Core系列处理器的计算机的好时机。处理器和英特尔(Intel)拥有多年保持产品线的历史。以他们的Core 2 Duo阵容为例。
Core 2 Duo处理器于 2006 年年中首次亮相。直到 2010 年，制造商仍然在新系统中推出这些处理器。酷睿(Core)i7、酷睿(Core)i5 和酷睿(Core)i3 处理器自 2008 年以来一直存在，并且不会出现在任何地方。此外，在 2016 年，英特尔(Intel)已从传统的滴答式更新周期转变为慢得多的三步流程、架构和优化周期。
以前，每一个托克都将是速度、效率和制造方面的重大升级。然而，现在证明这太难了。新周期增加了改进，我们每隔几年才会看到重大升级，例如从 14nm 到 10nm 芯片等。
英特尔(Intel)为其微处理器架构的每次新更新都赋予了代号。您可能听说过Broadwell、Haswell、Skylake、Skylake-X、Kaby Lake、Coffee Lake和Cannon Lake等名称。维基百科(Wikipedia)在这里有一个很好的表格，其中包含所有的代号和发布日期(codenames and release dates)。基本上(Basically)，对于消费者来说，不要担心下一代芯片，因为它不应该是市场上当前芯片的那么大的升级。
那么，您应该购买哪种处理器？最新的 18 核 36 线程 Skylake-X i9-7980XE 还是简单的 4 核Coffee Lake i3-8350K 成本仅为 i9 的十分之一？好吧，这完全取决于您的需求和预算。首先(First)，我们来看看每个品牌的处理器。
酷睿 i3
我们将从底部开始，然后逐步向上。Core i3 是英特尔最新的预算处理器。尽管Core i3 是同类产品中最低的，但它仍然是一款非常出色的处理器，得到了大多数专家和客户的好评。
Core i3 处理器背后的技术包括双核基础、超线程支持和虚拟化。Core i3 处理器确实支持 64 位版本的Windows。通过利用 Intel 的新芯片组和 14nm 技术，Core i3 可以很好地完成当今大多数计算任务。
此外，今年是Core i3 处理器 ( Coffee Lake ) 的第一年将有 4 个核心，而不是 2 个。每个核心基本上就像它自己的处理器，拥有的核心越多，一台计算机可以同时执行的任务就越多。
Core i3 和更高版本之间的另一个大区别是Core i3 不支持涡轮增压。涡轮(Turbo)增压是使处理器超频超过其基本时钟速度的能力。此外，最新的Coffee Lake i3 处理器已经放弃了超线程。
您应该购买配备Core i3 处理器的计算机吗？这取决于。如果您将计算机用于文字处理、电子邮件、网上冲浪、观看视频等基本任务，那么四核 i3 处理器足以轻松处理所有这些任务。对于大多数人来说， Core i3 处理器是一个可靠且负担得起的选择。
酷睿 i5
Core i5 是英特尔(Intel)最新的“中端”处理器。Core i3、i5 处理器的升级将使您的速度有明显差异，具体取决于您运行的应用程序的类型。如果您正在玩纸牌游戏，您将无法区分Core i3 和Core i5 处理器。如果您在Adobe Photoshop中编辑多个文件，您会注意到Core i5 可以更快地完成任务。
从技术上讲，Core i5 处理器的销售方式略有不同。Core i5 处理器主要分为三种类型：双核、四核和现在的六核。双(Dual)核 i5 处理器具有 32nm 和 22nm 技术、超线程支持、虚拟化支持和Turbo Boost技术。四(Quad)核 i5 处理器具有 45nm、22nm 或 14nm 技术、虚拟化支持和Turbo Boost技术，但不支持超线程。
最新的Coffee Lake i5 芯片也不支持超线程，但已增加到六个核心，而不是四个。
三种类型的Core i5 处理器是否提供相似的性能？对于单线程应用程序，六核将击败双核，但与四核相比不会产生巨大差异。但是，对于多线程应用程序，最新的六核将比双核和四核版本具有显着优势。购买 i5 时，请注意处理器中有多少个内核。
您应该购买配备酷睿 i5 处理器的计算机吗(Core)？在大多数情况下，如果您可以花掉多余的现金， Core i5 是一个安全的选择。(Core)Core i5 提供了足够的性能来处理视频编辑和游戏等工作，并且提供了足够的性能来处理文字处理、互联网冲浪和电子邮件等基本工作。Core i5 处理器是一款出色的中等价位处理器，适合经常使用计算机且经常执行多项任务的人。
酷睿 i7
接下来，我们有英特尔酷睿(Intel Core)i7 处理器阵容。Core i7 是当前所有(Core)Core系列处理器中的顶级芯片。直到Core i9 和Core X系列芯片。但是，Core i7 系列仍然相当昂贵。Core i7 也有几个不同的品种。区别在于芯片组。
在Coffee Lake之前，i7 系列拥有四核性能、虚拟化支持、超线程和Turbo Boost 技术(Turbo Boost Technology)。使用Coffee Lake，我们可以很好地提升到 6 个内核，就像 i5 一样，但 i7 支持超线程，所以我们总共有 12 个线程。
Core i7 处理器的主要用途是主要的多任务处理、繁重的多媒体任务、一流的游戏和繁重的计算任务。在运行多个虚拟机或在Premiere(Premiere)中编辑 4K 或更高视频时，您将看到 i7 的优势。
i7 处理器还具有更大的板载缓存，可以更有效地执行重复性任务。更大(Larger)的缓存也意味着更好的多任务处理性能。
您应该购买带有 i7 处理器的计算机吗？对于绝大多数人来说，这太过分了。使用 i5-8600K 之类的设备并将节省下来的钱花在更好的显卡或更多RAM甚至更快的SSD硬盘上会更明智。
但是，如果您偶尔执行 CPU 密集型任务或进行 2K 或 4K 游戏，i7 系列是一个绝佳的选择。
酷睿 i9
最后但并非最不重要的一点是，我们拥有新的Core i9 系列芯片，与其他产品阵容相比，这是一个很大的变化。首先，所有 i9 芯片都使用新的LG 2066插槽，这需要Intel X299芯片组主板。
i9 系列芯片也是英特尔(Intel)迄今为止发布的最强大的一组处理器。最便宜的有 10 个内核，一个巨大的 L3 缓存，现在的成本大约是 1 美元。最高端的 i9 拥有令人难以置信的 18 个内核（36 个线程），并且会让您回到廉价二手车的价格。
所有 i9 处理器也是Core-X系列处理器的一部分。Core i7 和Core i5 处理器也有Core-X版本，尽管 i9 处理器在基准测试中完全压倒了 i7 和 i5 版本。
您应该购买带有 i9 处理器的计算机吗？是的，如果你想要你能拥有的最酷、最快、最坏的电脑。准备好放下一些大笔现金。此外，当您获得具有如此高规格的处理器时，只有所有其他组件也都是高端的才有意义。你在这里说的是几千美元，所以 i9 从字面上看是用于 3D 动画、科学计算等。
结论和建议
无论您决定购买哪种处理器，您都将获得可以使用很长时间的优质处理器。但是，每次购买都是成本和性能之间的平衡。我的建议是使用CPUBenchmark 之(CPUBenchmark)类的网站来获取有关您正在考虑的每个处理器的详细信息。
例如，顶级酷睿(Core)i9-7980XE 的CPU价值得分很糟糕，因为它的成本很高：
将此工具与您的预算和需求一起使用，以确定要购买的最佳处理器。即使您不打算购买CPU ，也希望这能让您了解(CPU)Intel的(Intel)Core i3、i5、i7 和 i9 处理器之间的区别。享受！
CPU Processor Comparison – Intel Core i9 vs i7 vs i5 vs i3
Althоugh they’ve been out for more than a decade now, Intel’s Core lineup, Core i7, Core i5, and Core i3 proсessors, still feelѕ relatively young. Here, we will review the processors, explain the technologies behind them, lоok at Intel’s philosophy, аnd help you dеcide which processor to buy.
Rather than taking the traditional processor comparison route by showing you a bunch of benchmarks, game performance specs, etc., this review will focus on explaining the “core” of Intel’s core CPU lineup, which also includes the new Core i9 family.
Although benchmarks are useful for hardcore gamers, they are pretty much useless for the average computer user. This guide should help you pick out a computer, with a good processor for your needs, without having to know what “3DMark” is.
The first thing you may be wondering is if is now a good time to buy a PC with an Intel Core processor? It’s a bit disheartening for anyone to go buy something and find out the next day that the company just released a better model.
The answer is pretty much always yes, now would be a good time to get a computer with a Core series processor. Processors and Intel have a history of keeping product lines around for several years. Just look at their Core 2 Duo lineup as an example.
Core 2 Duo processors first made their debut in mid-2006. Those processors were still being put out by manufactures in new systems till 2010. Core i7, Core i5, and Core i3 processors have been around since 2008 and aren’t going anywhere. Also, in 2016 Intel has switched from the traditional tick-tock update cycle to the much slower three step process, architecture and optimization cycle.
Previously, every tock would be a major upgrade in terms of speed, efficiency and manufacturing. However, that has proved to be too hard now. The new cycle adds improvements and only every few years will we see major upgrades like going from 14nm to 10nm chips, etc.
Intel gives each new update to its microprocessor architecture a codename. You’ve probably heard names like Broadwell, Haswell, Skylake, Skylake-X, Kaby Lake, Coffee Lake and Cannon Lake. Wikipedia has a nice table here with all of the codenames and release dates. Basically, for the consumer, don’t worry about the next generation chip because it shouldn’t be that big of an upgrade from the current ones on the market.
So, which processor should you buy? The latest Skylake-X i9-7980XE with 18 cores and 36 threads or a simple Coffee Lake i3-8350K with 4 cores and one-tenth the cost of the i9? Well, it all depends on your needs and budget. First, let’s take a look at each brand of processors.
Core i3
We’ll start at the bottom and work our way up. Core i3 is Intel’s latest budget processor. Even though the Core i3 is the lowest of the bunch, it’s still a very good processor that has received good to outstanding reviews by the majority of experts and customers alike.
The technology behind Core i3 processors includes dual core base, hyper threading support, and virtualization. Core i3 processors do support 64-bit versions of Windows. By taking advantage of Intel’s new chipset and 14nm technology, Core i3’s perform very well for most of today’s computing tasks.
In addition, this year is the first year that a Core i3 processor (Coffee Lake) will have 4 cores instead of 2. Each core is basically like its own processor and the more cores you have, the more tasks a computer can do simultaneously.
The other big difference between Core i3 and the higher versions is that Core i3 does not support turbo boost. Turbo boost is the ability to overclock the processor beyond its base clock speed. Also, the latest Coffee Lake i3 processors have dropped hyper-threading.
Should you buy a computer with a Core i3 processor? It depends. If you use your computer for basic tasks such as word processing, email, surfing the web, watching video, etc., a quad-core i3 processor is more than enough to handle all of that with ease. A Core i3 processor is a solid, affordable choice for most people.
Core i5
Core i5 is the latest “mid-range” processor by Intel. A step up from the Core i3, i5 processors will give you a noticeable difference in speed, depending on the type of applications that you run. If you are playing solitaire, you aren’t going to be able to tell a difference between Core i3 and Core i5 processors. If you are editing multiple files in Adobe Photoshop, you will notice the Core i5 can complete tasks faster.
Technically, Core i5 processors are marketed a bit differently. There are three main types of Core i5 Processors: dual core, quad core and now six cores. Dual core i5 processors have 32nm and 22nm technology, hyper threading support, virtualization support, and Turbo Boost technology. Quad core i5 processors have 45nm, 22nm or 14nm technology, virtualization support and Turbo Boost technology, but do not have hyper threading support.
The latest Coffee Lake i5 chips do not support hyper threading also, but have been bumped up to six cores, instead of four.
Do the three types of Core i5 processors offer similar performance? For single-threaded applications, the six core will beat out the dual core, but won’t make a huge difference compared to the quad core. However, for multi-threaded applications, the newest six core will have a significant advantage over the dual and quad core versions. When purchasing an i5, be careful to note how many cores are in the processor.
Should you buy a computer with a Core i5 processor? In most situations, a Core i5 is a safe bet if you can spend the extra cash. Core i5’s offer enough performance to do stuff like video editing and gaming, and more than enough performance to do basic stuff like word processing, internet surfing, and email. A Core i5 processor is a great, mid-range priced processor for people who use their computers frequently and often multi-task.
Core i7
Next, we have the Intel Core i7 processor lineup. Core i7’s were the current top-of-the-line chips, out of all the Core series processors. That is until Core i9 and Core X series chips. However, the Core i7 series is still quite expensive. The Core i7’s also come in several different varieties. The is difference is in the chipset.
Before Coffee Lake, the i7 series had quad core performance, virtualization support, hyper-threading, and Turbo Boost Technology. With Coffee Lake, we get a nice boost to six cores, just like i5, but i7 supports hyper threading, so we get a total of 12 threads.
The main use for Core i7 processors is major multi-tasking, heavy multimedia tasks, top-notch gaming, and heavy computing tasks. You will see the benefits of an i7 when running a couple of virtual machines or while editing 4K or higher video in Premiere.
The i7 processors also have a larger on-board cache, which lets it perform repetitive tasks more efficiently. Larger caches also mean better multitasking performance.
Should you buy a computer with an i7 processor? For the vast majority of people, it’s overkill. It would be much smarter to go with something like an i5-8600K and spend the savings on a better graphics card or more RAM or even a faster SSD hard drive.
However, if you occasionally perform CPU-intensive tasks or do 2K or 4K gaming, the i7 series is an excellent choice.
Core i9
Last, but not least, we have the new Core i9 series of chips, which are a big change from the rest of the lineup. Firstly, all the i9 chips use the new LG 2066 socket, which require an Intel X299 chipset motherboard.
The i9 series of chips is also the most powerful set of processors that Intel has released by far. The cheapest one has 10 cores, a huge L3 cache and costs about a grand right now. The highest end i9 has mind-boggling 18 cores (36 threads) and will set you back about the price of a cheap used car.
All of the i9 processors are part of the Core-X series of processors also. There are also Core-X versions of Core i7 and Core i5 processors, though the i9 processors totally crush the i7 and i5 versions in benchmarks.
Should you buy a computer with an i9 processor? Yes, if you want the coolest, fastest and most wicked computer you can own. Just be ready to put down some serious cash. Also, when you get a processor with such high specs, it only makes sense if all the other components are high-end too. You’re talking several thousand dollars here, so i9 is literally for 3D animation, scientific calculations, etc.
Conclusion and Advice
No matter which processor you decide to buy, you’ll be getting a quality processor that will last you a long time. However, every purchase is a balance between cost and performance. My recommendation is to use a site like CPUBenchmark to get details about each processor you are considering.
For example, the top of the line Core i9-7980XE has a terrible CPU value score because of its high cost:
Use this tool along with your budget and needs to determine the best processor to purchase. Even if you aren’t planning on buying a CPU, hopefully this gives you a good idea on the differences between the Core i3, i5, i7 and i9 processors from Intel. Enjoy!
