In two days, Intel will introduce Arrow Lake-S desktop processors and the LGA 1851 platform for them. It was previously reported that the company would initially announce only five models of Core Ultra 200K processors with an unlocked multiplier. The latest large-scale leak of Intel promotional materials confirms this information, and also reveals the final characteristics of these chips.
Intel will indeed introduce only five processor models from the Arrow Lake-S series on October 10: Core Ultra 9 285K, Core Ultra 7 265K and 265KF, as well as versions of Core Ultra 5 245K and 245KF. It is noteworthy that the flagship model will not have a 285KF version without integrated graphics.
Intel’s published promotional materials report that the flagship Core Ultra 9 285K will be equipped with 24 cores (eight Lion Cove P-cores and 16 Skymont E-cores). The chip will receive 36 MB of Intel Smart Cache and 40 MB of L2 cache. The maximum processor frequency will be 5.7 GHz. The leak also confirms that not only the Core Ultra 9 models (like the Core i9 before), but also the Core Ultra 7 and Core Ultra 5 models will receive support for Thermal Velocity Boost automatic overclocking technology.
The Core Ultra 7 265K and Core Ultra 7 265KF models will each offer 20 cores (eight P-cores and 12 E-cores). These chips will be able to automatically overclock to a frequency of 5.5 GHz and will receive 30 MB of Smart Cache memory and 36 MB of L2 cache memory. The 265KF variant will lack integrated graphics. Let us recall that Arrow Lake-S will use a new “integration” based on the Intel Xe-LP architecture with four Xe cores. The new Core Ultra 9 and Core Ultra 7 will have an iGPU frequency of 2.0 GHz.
The Core Ultra 5 245K and Core Ultra 5 245KF processors will have 14 cores with a frequency of 5.2 GHz. These chips will be equipped with 24 MB of Smart Cache and 26 MB of L2 cache. The “K” variant will feature integrated graphics with 4 Xe cores running at 1.9 GHz.
All Arrow Lake-S series processors will support DDR5-6400 memory according to JEDEC specifications. Intel has confirmed the possibility of using up to 192 GB of RAM with the new platform, which is achieved by installing four sticks of 48 GB each. All expected processor models, which will be presented on October 10, will have an unlocked multiplier and support for manual overclocking. Their nominal TDP will be 125 W. The maximum power consumption of the Core Ultra 9 and Core Ultra 7 models will reach 250 W, and the Core Ultra 5 will have a maximum power consumption of 159 W.
For the first time for the desktop series of Intel processors, Arrow Lake-S chips will also be equipped with an AI accelerator (NPU) with a performance of 13 TOPS (trillion operations per second), which, however, is significantly less than the NPU performance of mobile Core Ultra 200V (Lunar Lake), which is 48 TOPS.
