Intel has published developer guides for the upcoming Alder Lake processors. In it, the chip maker confirms various base numbers for laptop and desktop models. The first Alder Lake CPUs are expected to be released on November 4.
Intel Corporation Reports on their website That there will be different variants for desktop and mobile applications, which will be available with different combinations of CPU and GPU cores.implementation units. The company reported that the Alder Lake-P laptop’s CPUs are up to six Powerful cores and eight energy-saving cores. The same has already been shown Leaked roadmapBut it has now been officially confirmed. Intel also writes that all Alder Lake SKUs for laptops come with electronic cores. Laptop models also get integrated GPUs of up to 96 implementation units.
The chip maker also writes that Alder Lake-S desktop processors get a maximum of eight P-cores and eight E-cores. Desktop models without electronic cores will also appear. This is in line with previous expectations; Recently appeared Intel Core i5-12400 With only six cores on it. You will also receive desktop SKUs with 32 . integrated GPUs implementation unitsIntel writes.
Basic types and instruction sets
The company is also publishing details about the different cores used in the Alder Lake chips. like the company Already confirmed, Alder Lake gets among the P-cores, codenamed Golden Cove. These cores are performance oriented and support bifurcation. At the same time, the electronic chips will receive the cores, which the company calls Gracemont. They focus on efficiency and don’t provide stress.
Both types are basic swimming pools Using L1 and L2 cache, so that they can work independently of each other. L3 cache shared. According to Intel, cores also support the same instruction sets. The manufacturer states that only P-cores support AVX-512, and that these instructions can only be executed when bios electronic cores are disabled. Ian Caters from Anandtech Posted on Twitter However, this is a bug, and AVX-512 is not supported at all in Alder Lake. “The Instructs It is updated. It has been confirmed that the AVX-512 is not in Lake Alder.”

Software improvements for Alder Lake
Intel is also focusing on software improvements for this hybrid architecture in its Developer Guide. Processors use Intel Thread Director. This should make the operating system user aware of the different performance and efficiency of the two types of cores. This allows the thread manager to split different computation tasks among the integer base types. Without this output, the operating system may think that all cores are of equal speed, and tasks can be distributed to the wrong cores.
The company shares many “optimization strategies” for app and game developers. Applications that are not in any way optimized for Alder Lake can still use the two core types thanks to the aforementioned Intel Thread Director, which attempts workloads It is automatically distributed between cores. This should provide better performance “in most cases”, but Intel wrote that in some cases it can prevent certain tasks from running on the wrong base type.
In the “good” scenario, where the developer has taken “a few steps” to Hybrid consciousness To create, the primary tasks will be divided between P-cores. Non-core background tasks should focus on electronic cores.
In the “best” scenario, developers create a task system that contains two thread pools to make. The core pool will focus on heavy duty computing intended for P-cores. The secondary thread pool should do “good for hubs” tasks. Intel cites several examples, such as audio mixingAnd Shading assemblyAnd asset flow, employment Pressure relief. Developers can also do basic tasks evacuation to electronic cores when performance cores are overloaded and there is residual capacitance on effective cores.
The company further confirms that it cooperates with argument-Companies to add support for the Alder Lake platform and its “hybrid architecture” for engines like Unreal Engine and Unity. This should happen in Future Releases. The company is also working with companies like Denuvo to ensure that some DRM software can recognize the structure of Alder Lake.
The first chips appear this quarter
Intel once again confirms that the Alder Lake platform will be rolled out worldwide in the last quarter of this year, although the chip maker itself hasn’t reported concrete data yet. Intel is expected to release the first Alder Lake models on November 4. Leaked information from MSI. This may include K and KF desktop processors, with the latter models having no integrated GPU. The first laptop chips and lower-rated desktop models are expected later.
