英特尔核心i9-12900k和核心i5-12600k评论

The 12th-gen chips also face added complications: they don’t play nice with a few games on Windows 10 and 11, and the physical size of the chip has grown, so many gamers will need a brand new motherboard and a kit to adapt their CPU coolers to fit on the new motherboard. Depending on which motherboard you get, you may need to buy new RAM as well, since some 12th-gen compatible motherboards only support the new DDR5 RAM.

尽管对于寻求高性能的非游戏者来说，新芯片可能是一个不错的选择，但所有这些都是一项巨大的投资，用于建立一个新的游戏钻机，该钻机并不比上一代更强大。

About the Intel Core i9-12900K / Core i5-12600K

While the majority of this review will focus on the higher-end Core i9-12900K processor, we also tested the more affordable Core i5-12600K.

这是我们测试的两个处理器的规格，首先列出了i9号：

• Total Cores:16 / 10
• 性能核心：8 / 6
• 效率核心：8 / 4
• Total Threads:24/16
• Max Turbo Frequency:5.20GHz / 4.90GHz
• Performance-core Base Frequency:3.20GHz / 3.70GHz
• 高效核心基础频率：2.40GHz / 2.80GHz
• Maximum Turbo Power:241W / 150W
• Processor Base Power:125W / 125W
• Cache:30MB Intel Smart Cache / 20MB Intel Smart Cache
• 总L2缓存：14MB / 9.5MB

Unlike Apple’s M1 chips, Intel’s 12th-gen processors feature hyperthreading, which helps boost their processing power. Intel’s chips are also an x86 type, whereas Apple’s chips are ARM-based, meaning that they process information in different ways. You canlearn more about how here。

What we like

令人难以置信的生产力表现

AMD’s Ryzen 9 5950X has been the consumer processor to beat with regards to multicore performance, which many photographers and filmmakers need to batch-edit or transcode their work as fast as possible. AMD consistently beat Intel in this area over the last few chip generations, but Intel’s new hybrid architecture has helped it pull ahead of AMD in this race.

在我们的3 d渲染测试中,英特尔的核心19 - 12900 k的rendered an image of a car in a mere one minute and 33 seconds, a full minute faster than the 11th-gen Core i9-11900K. Not only that, but the 12th-gen Core i9 was also five seconds faster than AMD’s Ryzen 9 5950X in the same test. (The Core i5-12600K was about 50 seconds behind its more powerful sibling.)

英特尔的最新芯片在我们的视频转编码测试中也表现出色，在该测试中，我们将12分钟的4K胶卷转换为1080p。AMD传统上在这项测试中也超过了英特尔，11代核心i9落后45秒，落后Ryzen 9 5950x（五分钟对4分钟和15秒），但核心i9-12900k在三分钟内转码了同一文件。和20秒。

Even better, the new Core i5-12600K was practically even with AMD’s Ryzen 9 5950X (which costs about $520 more MSRP), clocking in at four minutes and 22 seconds. This is quite remarkable considering the Core i5-12600K scored much lower than the AMD chip in all our synthetic benchmark tests. But like Apple’s M1 chips, Intel proves that a hybrid chip architecture can not only stand toe-to-toe with a traditional processor but can even beat it in practical applications.

我们的合成CPU基准测试进一步说明了英特尔的Core i9-12900k的原始处理能力，这使我们在消费者处理器中看到的最高数字。In our Cinebench R23 test, Intel’s chip scored a massive 26793 in the multicore performance test, while AMD’s high-end equivalent came in below that at 25173. Intel maintains the lead over AMD in single-core performance as well, scoring 1997 versus AMD’s 1614. While those numbers may not mean much in a vacuum, for content creators looking to get the fastest chip possible to shave off a minute or two of processing time, Intel is the clear pick.

The CPU performance gap between Intel’s 12th-gen chips and its 11th-gen chips is even larger, with the Core i9-11900K only reaching a score of 1663 in single-core and 15264 in multi-core performance.

What we don’t like

The new chip socket adds complications

英特尔的12代处理器的物理上比英特尔的前几代大，这意味着在2021年3月之前发布的任何英特尔500系列或更早的主板都不会与英特尔的新处理器兼容。无论您是升级当前的钻机还是从头开始构建第一台PC，都需要600系列主板。

That’s not so bad if you’ve been waiting to upgrade since Intel’s 8th or 9th-gen processor, as it would likely be time to get a new motherboard anyway. But if you have a 10th or 11th-gen Intel processor in a PC that you built within the last two years, you’ll have to drop a few extra hundred bucks for a new motherboard you otherwise wouldn’t need.

芯片的尺寸大一点so means you’ll need to get either a new CPU cooler or request a mounting kit from the manufacturer of your current one. The standoff screws that attach to both the motherboard and mounting bracket for earlier generations of Intel CPUs are too short for a cooler to be mounted properly on top of the 12th-gen processors. (I had to request a mounting kit for our Corsair cooler.) These mounting kits are for the LGA1200 or LGA115x socket—basically, any Intel desktop CPU that’s been made from 8th-gen to now.

To make a complicated compatibility situation even worse, your existing cooler might not even be compatible with the new motherboard you’ve picked out. The motherboard we used in our test bench has a hefty heatsink above the CPU socket, so that means beefy air coolers like Noctua’s NH-D15 will not fit since the heatsink on the motherboard doesn’t leave space for the air cooler to sit properly over the CPU socket. This is more of a motherboard issue than an Intel CPU issue, but if you’re going to get one of Intel’s new chips, just remember to make sure all your components are compatible.

Speaking of compatible parts, Intel’s 12th-gen chips support both DDR4 and DDR5 memory (DDR5 is a new RAM standard that reaches faster speeds, albeit with higher latency), but if you’re planning on swapping your current DDR4 memory to a new rig, make sure the 600 series motherboard you buy also supports DDR4. RAM is not interchangeable nor forward/backward compatible. If you buy a new motherboard for your new 12th-gen Intel chip that supports DDR5, but you only have DDR4, then you’ll need to buy new RAM—and DDR5 isn’t exactly cheap. (The motherboard we used in our test bench only supports DDR5.)

All of that said, the socket change that comes with Intel’s new processors doesn’t make building a PC on a tight budget easy—whereas Intel’s main competitor, AMD, has kept the same socket for several years now and has been offering its users excellent backward compatibility when it comes to newer CPUs and older motherboards.

游戏性能问题

如果所有关于主板，RAM和凉爽兼容性的东西还没有让您感到恐惧，那么游戏性能也许会。需要明确的是，游戏性能很好。这非常好，英特尔与游戏合作的处理器制作了一个处理器，这一点尤其引人注目。（苹果的M1并不是唯一一个很酷的大孩子。

However, not only dosome games likeAssassins Creed Valhalla在Windows 11上有Intel的新芯片问题我们也对Intel的第11代处理器的类似游戏性能的相似性以及帧速率有时如何在我们测试的图形卡中有时没有改善，我们也感到惊讶。

（（Note: Early December 2021, Microsoft released Windows 10 and 11 operating system updates that fixed many games’ compatibility issues with Intel 12th-gen chips. The majority of those games have been removed from Intel’s list, however, the problems we encountered below still existed even after applying the Windows 11 update on our test rig.)

从后者开始，在我们所有常规的游戏基准中，核心i5-12600k和核心i9-12900k都会输出完全相同的帧速率，但仅在与NVIDIA图形卡配对时。在1080p和最高图形预设上，Far Cry 5，，，，Shadow of the Tomb Raider， 乃至ControlandCyber​​punk 2077performed the same regardless of which CPU was paired with the RTX 3080 GPU.

我们预计会根据以前的测试从核心i9到核心i5的10 fps下降约10 fps，因此在这里并非如此。我们再次进行了相同的基准测试，但使用NVIDIA的RTX 3060 TI，并获得了相同的结果。

奇怪的是，当我们将相同的CPU与AMD的Radeon RX 6800 XT配对时，Core i9组合总是在Core i5组合上大约有10-15帧的领先优势。（我们取得了联系，以试图解决原因，但尚未得出结论。）

We ran the same benchmarks again with Intel’s Core i9-11900K and Core i5-11600K (11th-gen chips) paired with the RTX 3080 and then the RX 6800 XT, and the fps improvement was apparent with both GPUs; the 11th-gen Core i9 had an average of a 5-10 fps lead over the 11th-gen Core i5.

你应该买吗？

No, not unless you fit a very specific demographic

对于生产力和创造性任务，英特尔的最新CPU非常有能力帮助您加速产品。显然，英特尔的高性能和高效核心将其第12代桌面处理器与AMD和Apple竞争激烈。如果我们同时查看原始性能和现实世界的性能，英特尔将扫荡甲板。

但是，考虑DDR5 memory is not only expensive but also hard to find，，，，there’s greater value in building a PC with either an第11代英特尔or5000系列AMD处理器。两者都与更丰富，更便宜的DDR4 RAM兼容，与CPU冷却器和主板等硬件等硬件的兼容性问题较少，并且您可以通过购买稍旧的芯片来省钱。

最重要的是，与我们测试过的所有CPU/GPU组合相比，游戏性能没有太大差异。当与NVIDIA图形卡配对时，核心i9和核心i5 12代芯片的额外复杂性却吐出了相同的帧速率（我们仍在调查中）。如果您要从头开始构建游戏钻机PC，以替换五年或更长时间前建造的钻机PC，则核心i5可以为您节省一些钱。但是，大多数人会更好地跳过英特尔的第12代桌面处理器。
