1 00:00:00,903 --> 00:00:01,714 太长免读 2 00:00:01,809 --> 00:00:07,976 If you building on the cheap, a Pentium G4400 dual core around 60 bucks is your best bet. 如果你囊中羞涩，那么奔腾G4400可能你的最佳选择 3 00:00:08,039 --> 00:00:14,893 Because if you were willing to spend $92 for the G4520s marginal speed improvement 为了提升速度，如果你想要花92刀去买G4520的话 4 00:00:15,048 --> 00:00:22,468 the core i3 6100 is worth the extra 25 more thanks its higher clock speed and hyper threading. 多花25刀选择i3 6100以获得更高的频率和超线程技术是更好的选择 5 00:00:22,521 --> 00:00:26,974 from there if you are a heavier multitasker or a light content creator 如果你注重多任务或者搞创作 6 00:00:27,000 --> 00:00:32,035 the whole non-t core i5 lineup makes a fair amount of sense 那么i5系列就更适合你 7 00:00:32,060 --> 00:00:36,279 with the core i5 6500 coming in strongest in my mind 我强烈推荐6500 8 00:00:36,304 --> 00:00:43,919 thanks to it's 19% base clock advantage over the 6400 for only a 10% price premium 因为6500对比6400的话，以10% 的价格换取到了19%的主频提升 9 00:00:43,944 --> 00:00:51,520 if I was going to spend for an i5 6600 personally I pay the extra 20 or so for the K variant. 如果要买6600的话,我个人会多花20刀左右去买带k的版本 10 00:00:51,545 --> 00:00:54,687 It's got a higher TDP that means more power consumption 6600的功耗更大 11 00:00:54,712 --> 00:00:59,688 but with a extra investment into a Z series motherboard it supports overclocking 但是配合一块Z系列主板的话你就可以超频啦！ 12 00:00:59,713 --> 00:01:04,699 which can either give you a bit of extra ??? near the end of your computer's life span 这可以让cpu在它的有生之年跑快一些 13 00:01:04,724 --> 00:01:09,926 or incease the resale value when the time comes to sale it and start from scratch 亦或在你要升级换代的时候卖个好价钱 14 00:01:09,951 --> 00:01:15,461 this is basically as high as I'd go for a pure gaming machine 这基本上是我单纯为游戏主机所选的最高端cpu 15 00:01:15,486 --> 00:01:23,406 for aspiring content creators let's say gamers who alse stream or edit together their game plays for later upload to youtube 对于搞视频创作或那些需要直播和上传游戏视频到“有土鳖”的人来说 16 00:01:23,431 --> 00:01:29,892 the core i7 6700k takes everythings that's good about the 6600k 6700k在继承了6600k所有的优点的同时 17 00:01:29,917 --> 00:01:39,209 and adds hyper-threading more cache and the highest base and boost clocks across intel's entire generation lineup 增加了超线程技术，更大的缓存以及整个因特尔产品线最高的核心频率以及睿频 18 00:01:39,234 --> 00:01:43,542 you can find links to all of these processors in the video description 我就不翻译广告!哈哈哈! 19 00:01:43,567 --> 00:01:48,038 Okay so the TLDR is over kids let's see how we got there 好吧,"短平快"系列结束了.让我们来看看我们是如何得到这些结论的 20 00:01:48,063 --> 00:01:50,456 I'm gonna start with the "easy" way 我从“简单”的说起吧 21 00:01:50,481 --> 00:01:55,470 we'd out products that have zero customer reviews 我们找到一些没有用户评价的产品 22 00:01:55,495 --> 00:02:00,107 a given SKU. can have more reviews for a number of reasons 从最小库存管理单元可以看出一些原因 23 00:02:00,132 --> 00:02:09,411 sometimes its because the people who buy them have invested very heavily and feel compelled to show from the treetops especially to each other. 有时候花很多钱买这些另类cpu的人只是为了”装逼“（洋鬼子也好这一口儿） 24 00:02:09,436 --> 00:02:16,139 about how justified they were in doing so though the psychology of consumer behavior is far beyond the scope of this video 吹比用途和消费心理学不在本视频讨论范围之内 25 00:02:16,164 --> 00:02:23,648 the most common reason is that someone else out there has already done the grant work research to determine that 主要是因为有人已经看透了 26 00:02:23,673 --> 00:02:34,183 for example the core i3 6100 at $117 makes more sense than the i3 6300 at $138 举个栗子，117刀的6100比138刀的6300性价比高很多 27 00:02:34,208 --> 00:02:42,655 with its barely higher clock speed extra 1Mb cache and marginally faster onboard graphics 6300仅仅多了1Mb的缓存还有那微不足道的核显... 28 00:02:42,742 --> 00:02:48,770 there are exceptions to this but some solid indicators are side from the reviews 有例外但是从评论中有迹象表明 29 00:02:48,795 --> 00:02:56,106 are adequate stock and properly filled out product information pages and photos 像库存和正确的产品信息与照片 30 00:02:56,131 --> 00:03:01,560 not to mention the availability of a box version directly from intel 没有显示是否是盒装 31 00:03:01,585 --> 00:03:06,865 though for a specialty let's say a super low power consumption build 然而对于一些特殊要求例如超低功耗装机方案 32 00:03:06,890 --> 00:03:13,040 you might not to be able to avoid nonbox that is to say tray or OEM parts 你可能避免不了买散装cpu 33 00:03:13,065 --> 00:03:18,479 the core i5 6400T from the T low power series i5 6400T低功耗系列 34 00:03:18,504 --> 00:03:27,451 is a stand out there as a 35w true quard-core at 2.2-2.8Ghz for $170 35瓦 2.2主频睿频到2.8 售价170刀 35 00:03:27,476 --> 00:03:31,377 though we can see that the comparison here is somewhat unfair 由此我们可以看出单纯cpu对比有时候不是很公平 36 00:03:31,402 --> 00:03:36,036 because the real world pricing on similar chips like 6500T 因为市场上像6500T这样cpu的售价 37 00:03:36,061 --> 00:03:39,947 is way off of intel suggested price on ARK 要比intel的建议零售价高太多 38 00:03:39,972 --> 00:03:43,640 this is pretty normal on the excuse though 基于上述原因这也是情有可原 39 00:03:43,665 --> 00:03:47,822 and yet another reason to gravitate towards the higher volume 另一个原因是基于高销售量 40 00:03:47,847 --> 00:03:52,208 that every retailer and their dog is competing hard to sell 零售商们的主打销售不仅仅 41 00:03:52,233 --> 00:03:57,399 so that they not only sell the cpu but also all the other accessories that go with it 卖cpu而且还同时卖一些相关配件 42 00:03:57,424 --> 00:04:05,438 in fact for these high volume items it's not uncommon to see them going for even less than intels msrp on sale 实际上热销产品很少见到比建议零售价格低的 43 00:04:05,463 --> 00:04:12,669 Now lets go deeper you've probably noticed xeon processors sprinkled in with the core branded consumer ones 现在你可能注意到了至强系列正在亮瞎你的钛合金汪汪眼 44 00:04:12,694 --> 00:04:15,996 I included those in my spreadsheet for the sake of completeness 我把这些写进我的表格里只是强迫症病发而已 45 00:04:16,021 --> 00:04:24,613 but in a nutshell xeon's at the same specs in the same socket perform identically to desktop chips 但是简单地说，至强和同接口其他cpu的参数是相同的 46 00:04:24,638 --> 00:04:31,776 and differ from consumer cpus primarily in their ability to use ECC error-correcting memory which you can learn more about here. 与其他消费级cpu相比主要是多了ECC内存修正技术（ECC RAM 每面均有9枚内存颗粒，比普通的多1枚） 47 00:04:31,801 --> 00:04:42,765 Most 1000 series xeons can even actually run unofficially though in the same consumer LGA1151 motherboard 绝大多数至强1000系列都能在1151接口上运行（非官方指导） 48 00:04:42,790 --> 00:04:48,022 as everything else that I've talked about so far. So if you find one you like you can do that 其实至强也没啥新鲜的了,喜欢就买买买 49 00:04:48,047 --> 00:04:53,028 though please know that ecc memory support depends on the motherboard chipset too 但是要注意ECC需要主板芯片组支持才能发挥作用 50 00:04:53,053 --> 00:04:58,596 so you lose some of the benifit that you are usually paying extra for in that case 所以买至强基本就是钱多烧的（组工作站除外） 51 00:04:58,621 --> 00:05:02,377 moving up higher than the 6700k 接下来是6700k更吊的 52 00:05:02,402 --> 00:05:04,849 we are getting into two different territories here 我们下来要看两个方面 53 00:05:04,874 --> 00:05:11,586 both of which require moving up to the big boy pants socket LGA2011v3 他们都需要大个头的LGA2011v3 54 00:05:11,611 --> 00:05:16,784 prosumer professional use where dramatically reducing project time with 专业级消费能够显著减少工程时间 55 00:05:16,809 --> 00:05:21,409 more processing cores will improve productivity and therefore profit 更多的核心能提高生产率从而提高利润 56 00:05:21,443 --> 00:05:25,972 or because I can land where often knowing what they are doing 或者你有明确的使用目的 57 00:05:25,997 --> 00:05:32,135 enthusiasts consumers will drop obscene amouts money of knowing that they aren't getting a good value 懂点电脑的人都知道至强的性价比多低 58 00:05:32,160 --> 00:05:40,149 lets try to cover both of them all 2011v3 processors require a 50 to 100 dollar more expensive motherboard 让我们多花个50-100刀在主板上仅仅因为LGA2011v3接口 59 00:05:40,174 --> 00:05:49,640 but they support more pci express lanes and quad-channel vs dual channel memory though this is a dubious value to the typical gamer 但是其实这些主板支持多pcie和4通道内存，其实对于游戏玩家没卵用 60 00:05:49,665 --> 00:05:57,309 with core branded products and 1000series xoen eps limited to one cpu on a motherboard 1000系列的至强一个主板只能装一个 61 00:05:57,334 --> 00:06:02,078 2000series xoen eps pumping that up to two cpus on a motherboard 2000系列能装两个 62 00:06:02,103 --> 00:06:07,528 and DX class on is capable or running four cpus on a single motherboard DX级别的能装4个cpu在一块主板上 63 00:06:07,553 --> 00:06:10,578 so you'll pay significant premium for that feature 显而易见不嫌钱多就买 64 00:06:10,603 --> 00:06:15,074 in the core range the i7 6800 case stand out to me 说到多核心i7 6800就出现了 65 00:06:15,099 --> 00:06:22,065 it comes with a 28 pcie lanes so 2-way SLI the highest we recommend is all good 它支持28条pcie,所以要玩SLI的小伙伴们该上车了 66 00:06:22,090 --> 00:06:27,153 you get 94% the clock speed at 73% of the price 相比6850k七分钱就能买到九分的主频 67 00:06:27,178 --> 00:06:33,462 compared to the 6850k which also got 40 pcie lanes if you're an expansion fiend 6850k有40pcie通道 68 00:06:33,487 --> 00:06:40,898 and like the rest of the HDDT high-end desktop core i7 supports overclocking 支持超频（请上水冷） 69 00:06:40,923 --> 00:06:46,850 meanning that the clock and architectural disadvantage vs the 6700k that 意味着主频和架构相比6700k都要更新缓慢 70 00:06:46,875 --> 00:06:52,658 comes with being based on the slower updated server work station platform 因为是工作站级的东东 71 00:06:52,683 --> 00:07:01,069 are a little more palatable given the reasonable $100 premium for fifty percent more processing cores its got 6 of them 但是多花100多刀就能有6个核心 72 00:07:01,094 --> 00:07:09,787 the rest of the 2011v3 core i7 seem to be priced more like high clock speed high power consumption xeon skews 剩下的2011v3接口的i7看起来都不如这个性价比高 73 00:07:09,812 --> 00:07:14,692 the 1650k and 6900k hold their own pretty well 1650k和6900k 贵的飞起 74 00:07:14,717 --> 00:07:23,484 against the very similar E5-1650 and E5-1660 if you want to trade ecc support for overclocking 相比之下E5-1650和E5-1660相当于用ECC技术交换了超频 75 00:07:23,509 --> 00:07:28,009 but as for the 10 cores 6950x extreme edition 但是大杀器 i7 6950x来了 76 00:07:28,034 --> 00:07:34,071 while it enjoys a significant max turbo boost clock speed advantage over the entire xeon range 在享受超过至强全线的最高睿频的同时 77 00:07:34,096 --> 00:07:40,704 with a couple of exceptions including this weird quad-core that I wouldn't recommend over a lower-priced LGA1151 model 当然这种1151接口的低级货至强不在对比范围之内.. 78 00:07:40,729 --> 00:07:47,101 its doesnt make as much sense to me as the similarly priced E5-2680 v4 对我来说其实E5-2680v4似乎是更好的选择 79 00:07:47,126 --> 00:07:53,615 I mean if you need 10 cores wouldnt you also benefit from 14 and probably ECC 都需要10核心了，想必14核心一定更符合需求，也许ECC也用的上 80 00:07:53,640 --> 00:07:56,772 because thats the basic process for choosing a xeon 因为这些基本上是你选至强的理由 81 00:07:56,797 --> 00:08:04,890 in theory clock speed times the physical cores and total logical cores provided by hyper-threading technology to learn more about here 理论上说主频乘以物理核心数和逻辑核心数等于总体性能 82 00:08:04,924 --> 00:08:13,242 where applicable for mutil-threaded workloads like cpu-based video encoding or 3d modeling and scientific number crunching 对于基于cpu的编码作业，例如视频渲染，3d建模等 83 00:08:13,267 --> 00:08:16,766 will give you total performance sort of 84 00:08:16,791 --> 00:08:23,426 and you need to weight that then against your sensitivity to high power consumption and high price 然后你还要考虑是否承受得了动辄上140w的功耗 85 00:08:23,451 --> 00:08:26,051 though again it isn't quite that simple 然而事情也并非这么简单 86 00:08:26,076 --> 00:08:35,139 the base clock is not necessarily representative of the speed at which the chip will actually operate and neither is the boost for that matter 主频也不一定代表实际的操作速度，睿频也一样 87 00:08:35,164 --> 00:08:41,611 this handy chart that i found for current generations xeon EP processors reveals 我找到的这个表格揭露了至强EP处理器 88 00:08:41,636 --> 00:08:48,342 that in heavy AVX loads the 14 core 2694 costs 20% more 在满载情况下14核心的2694比2680v4多用20%功耗 89 00:08:48,367 --> 00:08:55,134 than a 14 core 2680v4 and appears to enjoy a 10% clock speed advantage 去提升10%的主频 90 00:08:55,159 --> 00:09:05,178 but in actuality only runs 7% faster with up to 6 cores boosted and only three and a half percent faster with all 14 cores 但是实际仅仅比6核心至强快7% 比其他14核心也之快了3.5% 91 00:09:05,203 --> 00:09:13,674 furthermore for workstation use virtualization that technology that allowed me to have 10 gamers running off with a single computer here 工作站使用虚拟机让是个玩家同时用一台电脑进行游戏 92 00:09:13,699 --> 00:09:19,716 or bursty a single-threaded application use gamers love high-performance cores 或者是有游戏玩家喜爱的单线程高睿频 93 00:09:19,741 --> 00:09:25,983 high boost clocks can be as important as many cores if not more so 更高的睿频在游戏玩家眼里比更多核心要重要 94 00:09:26,008 --> 00:09:32,024 as our comparison between the 6700k quad core which costs 350 bucks 与6700四核相比要贵350刀 95 00:09:32,049 --> 00:09:41,448 and the 6850x10 core which cost 1700 demonstrated with the 6700k being a clearly superior gaming chip 贵1700刀的6850x10显然不如6700k性价比高 96 00:09:41,473 --> 00:09:46,647 due to its higher peak clock speed ill have that chart link below as well 因为6700k的睿频更高 97 00:09:46,672 --> 00:09:53,818 which leads us to tow more things i haven't touched on some specialized features like 下来还有一些我们没有讨论到的特性 98 00:09:53,843 --> 00:10:00,935 trusted execution technology if you need that your decision is pretty simple by one of the few skews that supports it 例如Intel受信任执行技术，只有几款至强有此功能 99 00:10:00,960 --> 00:10:06,582 and finally it almost never make sense to buy a last generation cpu brand-new 当新一代cpu上市之后买新不买旧 100 00:10:06,607 --> 00:10:13,717 clearance deals do happen but they're rare because intel usually carefully managed supply in their distribution channels 清仓甩卖几乎不会发生因为intel有很好的库存管理 101 00:10:13,742 --> 00:10:21,760 so basically nothing is left by the time the new ones start hitting shelves usually at he same price for somthing slightly better that the old one 基本上新品上架就意味着相同价格，新品具有更好的性能 102 00:10:21,785 --> 00:10:24,831 second hand chips on the other hand can be a steal 二手cpu就另当别论了，有时候会很超值 103 00:10:24,856 --> 00:10:33,751 I'd take this aging 6 core for $200 at the time of writing and overclock the stuffing out of it over our current generation quad for certain workloads 我前些日子组了一个6核心cpu才花了200刀，超频以后性能超过了当代的四核产品 104 00:10:33,786 --> 00:10:41,993 but watch out cpus especially the older ones generally out last their motherboards by a considerable margin 但是买二手cpu要考虑适配合适的主板 105 00:10:42,018 --> 00:10:51,692 so finding a compatible board at all let alone one at a reasonable price with a somewhat up-to-date feature-set can make this approach less feasible 因此，找到一个兼容的板，还要有一个合理的价格与一个最新的功能集，这基本上来说很难 106 00:10:51,717 --> 00:11:00,161 so then have you made it this far and still feel lost I'll have some references I talked about some of the link in the video description worst-case scenario
