Bộ Xử Lý Intel® Core™ I5 Thế Hệ Thứ 7

After talking up Alder Lake for more than a year, we have our first batch of Intel’s 12th-gen chips. This new generation brings the same slew of performance improvements you’d expect out of a typical CPU generation, but also marks the first time hãng sản xuất intel has used its 10nm manufacturing process on desktop và it’s the first slot-in CPU with a hybrid architecture.

There’s a lot khổng lồ talk about with Alder Lake, from how the chips are designed lớn how they perform in the real world. We rounded up everything you need lớn know about 12th-gen Alder Lake processors, including how much they cost, what kind of performance you can expect, and how they work with new Z690 motherboards.

Pricing & availability


The first batch of Alder Lake chips arrived on November 4, though we should see more products in the future. The company announced them during the hãng sản xuất intel Innovation event on October 27, revealing six new CPUs khổng lồ kick off the range. They’re split into three groups of two, with a K-series và KF-series model available for each SKU:

Core i9-12900K — $589Core i9-12900KF — $ 564Core i7-12700K — $409Core i7-12700KF — $384Core i5-12600K — $289Core i5-12600KF — $264

The prices are much lower than we expected. Earlier leaks pointed khổng lồ prices nearing $1,000 for the flagship chip. At least in the U.S., hãng sản xuất intel didn’t raise prices much over 11th-gen chips. The i9 và i5 models have seen a slight bump, while the i7’s pricing is the same as the previous generation.

Although there are six processors available, they come in groups of two. The K-series chips are more expensive because they feature integrated graphics, which the KF-series chips vày not. That’s the only difference between the chips, so the core i9-12900K and Core i9-12900KF should be identical in terms of CPU performance.

The leaked box was real, too. The box designs are mostly unchanged from the previous generation, however, the flagship core i9-12900K comes slotted inside a golden wafer replica in the box, confirming an earlier leak.


With the release of the first Alder Lake processors, we have our first look at the specs. They confirm earlier rumors overall, with the top cpu sporting 16 cores split evenly across P-cores & E-cores. Here’s how the range looks at the moment:

All of the chips come with a phối of P-cores and E-cores, but the balance is different for each model. Only the P-cores tư vấn hyperthreading, so the i9 mã sản phẩm comes with 16 cores and 24 threads, the i7 mã sản phẩm comes with 12 cores & 20 threads, and so on.

All of the chips come with a 125-watt rated nguồn limit, though they can boost much higher. The flagship core i9-12900K can climb as high as 241W when boosting. Still, that’s technically less than the bộ vi xử lý core i9-11900K, which could boost as high as 250W when pushed. Hãng sản xuất intel has stressed the efficiency of the new design, saying the i9-12900K can deliver the same peak multi-threaded performance as the i9-11900K while consuming only 65W.

Frequency-wise, it’s hard khổng lồ lock Alder Lake down. The P-cores và E-cores run at different frequencies, so there isn’t a single number khổng lồ reference. With Intel’s updated Extreme Overclocking Utility (XTU), you can tweak the P-cores & E-cores independently khổng lồ dial in an overclock.



With Alder Lake finally here, we can validate some of Intel’s performance claims. In our testing of the chip core i9-12900K, we found massive gains over the previous generation & a significant lead over the competing Ryzen 9 5950X.

Gaming is a big focus of Alder Lake. Hãng sản xuất intel says the generation brings up lớn a 28% improvement in games lượt thích Hitman 3 over the previous generation. Some of that is on the back of Windows 11, which is optimized for Alder Lake’s Thread Director feature, & DDR5 memory, which benefits games with its increased bandwidth.

Our own benchmarks back up the improvements in games. In the synthetic 3 chiều Mark Time Spy, the core i9-12900K was about 8% faster than the Ryzen 9 5950X & Core i9-10900K. In a real game, Forza Horizon 4, the 12th-gen cpu managed a massive 16% lead over the other two processors. This is a much wider gap than an early leaked benchmark of the same trò chơi suggested.

Assassin’s Creed Valhalla118 fps121 fps122 fps
Forza Horizon 4234 fps201 fps200 fps
Civilization VI (turn time, lower is better)7.3 seconds7.5 seconds6.5 seconds

Still, not all games saw a benefit. Red Dead Redemption 2 is one example, as the chip core i9-12900K just barely managed to lớn outclass the Ryzen 9 5950X. Similarly, the chip produced a slightly lower frame rate than even the core i9-10900K in Assassin’s Creed Valhalla, which Ubisoft confirmed has a problem with this processor.

Although gaming is important, Alder Lake is also focused on multitasking and content creation. In a common scenario where you’re playing a trò chơi while streaming and recording, hãng sản xuất intel says the bộ vi xử lý core i9-12900K can deliver an 84% improvement in frame rate over the previous generation. Hãng intel says the new chips are also up khổng lồ 36% faster in photo-editing applications like Adobe Lightroom, 32% faster in Premiere Pro, and 37% faster in Autodesk Revit.

Those numbers are accurate based on our testing. In Photoshop, the vi xử lý core i9-12900K was about 30% faster than the Ryzen 9 5950X, & in Premiere Pro, it was about 7% faster. The chip also produced an impressive 47-second render in Handbrake, marking a massive 35% improvement over the chip core i9-10900K.

In general computing, the Alder Lake still shows its power. Take Geekbench 5, for example, where the core i9 mã sản phẩm managed a 28% lead over the Ryzen 9 5950X. This is a much larger gap than in early leaked benchmarks, where the cpu only managed a 3.8% lead. The extra jump is on the back of increased DDR5 memory speeds. Going down to DDR4, the bộ vi xử lý core i9-12900K is actually slower.

LLeaked Cinebench results showed the core i9-12900K performing about 21% above Ryzen 9 5950X. In our testing, the two chips produced almost identical scores in the multi-core test, but Intel’s cpu managed nearly a 30% lead in the single-core test.

We’ve only tested the core i9-12900K, & there are only a small number of Alder Lake chips available right now. We have some leaked benchmarks for upcoming chips, though.

The most recent leaked benchmarks we have come from CPU-Z, where the bộ vi xử lý core i7-12700K bested AMD’s Ryzen 7 5800X by a massive 45%. This is the clearest showcase of Alder Lake’s power yet, lining up with what hãng intel has been promising for over a year.

Another leaker also posted CPU-Z benchmarks for the bộ vi xử lý core i5-12400. This processor is rumored khổng lồ only come with Golden Cove P-cores, but it still managed a 40% lead over the Ryzen 7 2700X in the single-core test. In Cinebench R20, the bộ vi xử lý core i5-12400 beat out every Ryzen 5000 cpu in the single-core chạy thử while managing a decent lead over the Ryzen 5 5600X — which has the same number of cores — in the multi-core test.

Architecture design


Alder Lake uses a hybrid architecture that brings together two types of processing cores. The first is a performant chip core that mirrors what you’d typically find in a new processor generation, & the second is an efficient bộ vi xử lý core that’s used khổng lồ handle background tasks và beef up applications that like a lot of cores.

Intel is designing both cores on hãng sản xuất intel 7, which is the new name for the Enhanced 10nm SuperFin process node. Golden Cove cores are the big ones, và they handle the bulk of work you’d vày on a computer. Gracemont cores are the little ones, và they’re useful for handling background tasks or conserving battery life when a performant vi xử lý core isn’t needed.

Golden Cove cores are focused on high-frequency, single-threaded performance. Utilizing Intel’s new Matrix engine, the company says that the cores should have higher frequencies across applications. The Matrix engine is a coprocessor that handles matrix multiplication, which can tốc độ up A.I. Workloads, in particular.


Gracemont cores handle the other side of the performance spectrum. Hãng sản xuất intel says they’re all about multi-threaded performance, juggling several lightweight tasks across multiple cores. Hãng intel says they can perform about 40% above old Skylake cores at the same wattage.

Bringing the two vi xử lý core designs together is a series of high-bandwidth interconnects. The Compute Fabric ties the two cores together with up to lớn 1,000GBps of bandwidth, the I/O Fabric delivers up khổng lồ 64GBps of bandwidth between inputs & the memory subsystem, và the Memory Fabric offers up to 204GBps of bandwidth between the memory và the rest of the processor.

Other changes to lớn Alder Lake include support for PCIe gene 5 và PCIe ren 4, as well as DDR5 & DDR4 memory. Though Alder Lake will support both generations of DDR system memory, it will be up to the board manufacturer khổng lồ decide which standard to lớn support. Users won’t be able to mix DDR4 và DDR5 modules on the same board. Thunderbolt 4 và Wi-Fi 6E Gig+ will also be supported on Alder Lake.

DDR5 modules support XMP 3.0. This new version of XMP comes with a bunch of upgrades, including up to two user-defined profiles, five onboard profiles overall, and tư vấn for tweaking in the operating system.



Alder Lake chips feature a thicker integrated heat spreader (IHS), which should give them more overclocking potential. Intel trimmed the die thickness and thermal interface material down lớn increase the IHS size, adding more bulk metal khổng lồ the đứng đầu of the chip for greater cooling potential.

Alder Lake marks the launch of Extreme Tuning Utility (XTU) 7.5, which allows you lớn tweak the ratio and voltage settings of Alder’s P-cores and E-cores. You can overclock each of the cores independently. If you can’t be bothered, you can use intel Speed Optimizer on the bộ vi xử lý core i9-12900K and Core i9-12900KF to add a moderate overclock with a single button.

In our testing, XTU boosted the chip to 5.0GHz all-core without increasing heat or power nguồn draw. With some manual tweaking, we managed a 5.4GHz overclock without much of a hassle, though it came carried a 300W power nguồn draw with it.

New socket và Z690 motherboards

Bill Roberson/Digital Trends

Intel is moving khổng lồ the Z690 platform with Alder Lake, which features the new LGA1700 socket. Many motherboard manufacturers, including Gigabyte, MSI, Asus, Colorful, & ASRock, have boards available with the new chipset và socket. Alder Lake supports DDR4 và DDR5,, but as mentioned above, you won’t be able khổng lồ use both on the same motherboard.

DDR5 features the same number of pins as DDR4, but it has a different layout. Motherboard makers will choose which standard they want to support, and you can’t switch between them.

A new socket means a new layout for CPU coolers. Many CPU cooler makers, including Noctua, are offering miễn phí brackets that work with the LGA1700 socket.

Thread Director và Windows 11

Alder Lake can leverage Windows 11 in a way a processor never has before. Thread Director is a new hardware-level feature on Alder Lake processors that helps the operating system — Windows 11, in particular — know how to lớn assign tasks to lớn different cores.

As mentioned, Alder Lake is a hybrid architecture that uses performant và efficient cores. Normally, an OS chooses which tasks go where through a combination of calculations (such as if the task is in the foreground or background) và guessing. The result is inefficient thread scheduling, which is a big giảm giá khuyến mãi for a hybrid CPU.


Enter Thread Director. With this feature, hãng sản xuất intel is able to offer Windows 11 full visibility into what kind of workload the task is handling. That removes the guesswork from the equation, helping the operating system better assign tasks khổng lồ appropriate cores.

Thread Director hits on two fronts. Although Alder Lake doesn’t have the first hybrid CPU architecture, most previous versions have focused on battery life & efficiency. Thread Director allows the processor to lớn reach a peak performance state when tasks hotline for it while conserving battery life when the machine doesn’t have a large workload.

“We didn’t want khổng lồ sacrifice,” hãng sản xuất intel client architect Rajshree Chabukswar told Digital Trends. “It’s really about keeping in mind.”

Right now, Windows 11 will see the biggest improvement, but hãng intel tells us that Windows 10 will see some improvements, too. Down the line, hãng sản xuất intel says it hopes khổng lồ work with more partners to lớn bring Thread Director support to other operating systems. Based on leaked benchmarks, Alder Lake could offer up to an 8.2% improvement in single-threaded workloads on Windows 11.

Our testing backs that up, with PC Mark 10 showing a 15% improvement with the core i9-12900K on Windows 11. A lot of applications don’t see much of a benefit, however. In our suite of benchmarks, only PC Mark 10 showed a significant improvement on Windows 11.

Alder Lake-P sản phẩm điện thoại processors


Alder Lake is a platform for Intel. The company is using the same name & architecture across its desktop và mobile releases, breaking from the launch cadence it has established. We don’t know much about Alder Lake-P right now, but a few leaks have offered glimpses at the upcoming range.

Both come from a rumored revision lớn the Samsung Galaxy Book. This machine will reportedly come with either a 12-core or 14-core Alder Lake-P chip. Both come with eight E-cores, but the 12-core model comes with four P-cores while the 14-core comes with six.

Keeping with the theme of simplifying naming schemes, intel is set to use Alder Lake-P as the name for all of its điện thoại chips. Previous generations featured revisions with higher nguồn limits, but Alder Lake-P chips will reportedly operate anywhere from 12W to 45W. You’ll likely find these everywhere from budget notebooks to high-end gaming machines.

Mobile Alder Lake chips aren’t here yet, but there is a leaked benchmark khổng lồ reference. In the test, the flagship core i9-12900HK boasted a 44.8% improvement in multi-core performance over the previous generation, and it was able to squeeze out a small 3% over Apple’s M1 Max.
