In this article, we have mentioned all the details of Intel’s 12th Generation Alder Lake mobile processor family. Responding to AMD with Alder Lake, the chipmaker completed the desktop series with the CES 2022 event and released all of its remaining 22 chips to the market. The company also announced that the more affordable H670, B660 and H610 chipset series will be available soon.

Before we start, let’s say that you can take a look at this article to see all the details about the 12th Generation Alder Lake platform. Additionally, we reviewed the Core i5-12400 model here, which is a good option for gamers when it comes to price/performance.

However, we have details on the Laminar stock cooler lineup, which has been circulating for a while and comes with non-K processors. These new coolers offer more powerful cooling and RGB lighting to compete with Ryzen stock coolers.

As before, most of the new chips come with two variants: full-fledged processors with integrated graphics and F-series processors devoid of iGPU, which offers low cost. All of the introduced chips follow the basic principles of the K-series and support PCIe 4.0 and PCIe 5.0 interfaces. Besides, DDR4-3200 and DDR-4800 native memory support remains the same.

At the same time, all new processors are multiplier unlocked and overclocking is not allowed. But Intel, as you can imagine, allows memory overclocking on all its chips.

The $489 Core i9-12900 and $339 Core i7-12700 models are pretty much the same as their K-series counterparts. While the core counts do not change, the frequency speeds are lower due to the 65W TDP limitation. In addition, Intel reduced the Maximum Turbo Power (MTP) on the Core i9 and i7 models by 39W and 10W, respectively. Naturally, these power limitations cause performance degradation. However, compared to the K series, the processors run cooler and come as more budget-friendly solutions.

The Core i5 series draws attention with its pricey yellows, ranging from the Core i5-12600, which is priced at $223, to the Core i5-12400, which is listed at $167. Moreover, if you have an external graphics card, prices are lowered with the F series. Along with the high-end 12500 or 12600 processors, UHD Graphics 770 integrated graphics are included in the processors. Therefore, CPUs may be more interesting for pre-stuffed systems or those who don’t mind using a discrete GPU. Additionally, Core i5 processors do not have additional efficiency cores.

Intel’s Core i3 series again lacks Gracemont productivity cores and has eight threads along with four performance cores. The Core i3-12100F comes with a list price of $97, while the Core i-312300 is priced at $143.

Unfortunately, both Intel and AMD have begun to pay little attention to the sub-$140 processor market after the continued wave of chip prices. We hope that the production and stocks of suitable fiadollar-like processors will be sufficient.

Intel also didn’t forget the Pentium Gold G7400 and Celeron G6900 processors for the ultra low end. These dual-core chips carry four threads and are powered by a low-end UHD Graphics 710 engine. CPUs with 35W TDP can be ideal for small form factor systems and everyday use.

Here you can see Intel’s own tesdollar series. The Blue team compared the Core i5-12600 and Core i9-129900 to the Ryzen 7 5700G for a variety of productivity and creativity workloads. As you can imagine, Intel’s chips excelled in these benchmarks.

Intel has also shown impressive performance gains for the Core i9-12900 over the previous generation i9-11900, positioning its new chip as a great solution for mainstream gamers. Of course, there are many Core i5 and Core i7 processors that can be preferred for acting. The 6-core Core i5-12400, which we examined in detail and made the tesdollar series, is one of them.



We’ve already seen Intel’s new Laminar coolers a few times in past leaks. These coolers are designed to address two major shortcomings in Intel’s stock coolers: thermal dissipation limitations and aesthetics. AMD’s stock coolers had long outstripped Intel in both respects.

Laminar heatsinks plug into the LGA1700 socket and come in three variants: The Laminar RH1 has controllable aRGB lighting and is supported by a large copper block to improve thermal dissipation. The company also claims that this cooler, which comes with Core i9 processors, works very quietly (2.6 BA).

The Laminar RM1 will be packaged with non-K Core i7, i5 and Core i3 CPUs. We have bad news for those who care about RGB, there is no RGB lighting on the RM1 and a decorative blue lighting is used. Blues again rates this cooler for “silent performance” at 3.9 BA.

The lower-end Laminar RS1 completes the new family of coolers, but the smallest in the series will only ship with lower-power Pentium and Celeron chips. The cooler doesn’t have a noise rating listed, so let’s add in the possibility of it running pretty loud.

Intel will also sell these coolers separately from the chips. These need to be purchased in large numbers and users cannot buy directly from Intel. Still, we expect these coolers to reach retail outlets through third-party vendors.

The technology giant plans to solve the problem of high motherboard prices by launching the H670, B600 and H610 chipset series. We expect new motherboards with this sedollar series of chips to support predominantly DDR4 memory at lower cost. It was also said that the company will avoid PCIe 5.0 technology to save cost on some motherboards.

Except for the H610 series, all motherboards will support Sars memory overclocking (XMP 3.0). As for the I/O unit, the H670 will have PCIe Gen 5 slots (x16 or x8/x8 electric), while the remaining motherboards will have a single Gen 5 slot. As for DMI, the H670 chipset will have 4.0 x8 connectivity while the B660 and H610 will have 4.0 x4 connectivity. Gen 4 lanes have the H670 12 lanes and the B660 6 lanes in terms of series. The H610, on the other hand, has no Gen 4 lanes. For PCIe Gen 3, there are 12 lanes on the H670 and 8 lanes on the B660/H610 motherboards.

Anakardollarsar will have lower price points than the Z690 series, and the H610 models are expected to come in under $100 options. It’s nice that DDR4 support is available because DDR5 RAMs are either too expensive or hard to find in stock due to supply issues.

Intel does not find the modular CPU core chip approach sensible to build the high core processors used by AMD. The hybrid architecture approach adopted in this context is an important innovation in the x86 market. Alder Lake-S silicon is a monolithic die fabricated on the Intel 7 process formerly known as 10nm Enhanced SuperFin. Silicon uses the same layout as the Intel client processor from the past, with a central last-level cache (LLC or L3 cache) and a bidirectional ringbus connecting various blocks (parts of the processor).

The most important blocks are CPU cores, and as we said, up to 16 can be used in Alder Lake-S. The much larger Golden Cove performance cores make up half of that, while the other half are clustered with Gracemont cores. Each of the eight performance cores has its own special ring-stop feature. Groups of four efficiency cores (E-cores) form a single core cluster. There are two such E-core bands in Alder Lake-S, each with a ring stopper. In other words, it is possible to disable all P-cores in the processor individually, but E-cores can only be disabled on a cluster basis. Also, at least one performance core must be active on the CPU; therefore it is not possible to run the CPU with efficiency cores only. On the contrary, it is possible to disable all efficiency cores for a processor consisting of performance cores.

Alder Lake-S silicon has 30MB of shared L3 cache accessible by all elements in the silicon, including P core, E-core clusters, iGPU (integrated GPU), memory controllers, PCIe root complex, and other components. Each of the eight P cores has a dedicated 1.25MB L2 cache. Each E-core cluster benefits from 2MB of L2 cache shared between the four cores.

Hybrid Architecture and Intel Thread Director

Intel Thread Director is a highly specialized middleware that interfaces with the operating system and software on one side and two sets of CPU cores on the other. Its job is to analyze a workload and help the OS scheduler distribute it at a granular level (both at the process level and at the thread level) among P-core or E-core clusters. Also, Windows 11 operating system is required for this process, but Windows 10 should still work well with chips because Alder Lake also includes support for “preferred cores”.

Windows 11 also introduces the concept of quality of service (QoS) for software. This basically allows applications to communicate with the operating system about workloads and gives Windows Scheduler a clue as to whether performance cores (P-Core) deserve their resources or can be relegated or even restricted to productivity (E-Core) cores.

To achieve this, Thread Director can monitor the operation of the processor with nanosecond precision. There is mostly ISA consistency between the two types of cores, but some processes may need features available only on P cores, such as AMX or DLBoost. Thread Director, on the other hand, will ensure that such operations are allocated to performance cores only. Dialogue between Thread Director and OS scheduler also ensures that background or idle processes are routed to productivity cores.

Review

Intel’s Alder Lake chips seem to outperform Ryzen 500 chips in almost every model in terms of both price and performance. The Z690 chip sedollar series was quite expensive. B660 and H610 motherboards, which will be released, will be a good match with these processors. On the other hand, you will be able to choose one of the motherboards that offer DDR4 or DDR5 support with these processors.
