Rumors are swirling in the tech community as we approach the anticipated launch of Intel's 15th Gen Arrow Lake CPUs, a product line promising to be a major leap in technology and performance. From ditching hyperthreading to potentially changing CPU cooler compatibility, Arrow Lake is packing a punch. Based on recent leaks and industry buzz, here's what we know so far.

A Closer Look at Arrow Lake's Core Count and Launch Date

Intel's 14th Gen CPUs are set to launch later this year with a Raptor Lake-S Refresh for desktops and Meteor Lake-P for notebooks. Following this, the 15th Gen family will primarily feature Arrow Lake products.

The first wave of Arrow Lake chips is reported to top out at 24 cores (8P + 16E) with a launch date in late 2024. Moore's Law is Dead suggests that a 40-core variant with 8P and 32E cores is in the Q2 or Q3 2025 pipeline.

Interestingly, Arrow Lake is expected to be the first mainstream Core family to drop Hyper-Threading (Simultaneous Multi-Threading). With neither 2-way nor 4-way Hyper-Threading aligning well with the P-cores, single-threaded performance has been prioritized.

Rentable Units and a 40% Uplift

Replacing Hyper-Threading, Intel plans to introduce Rentable Units (RU), which sounds suspiciously like DLC-styled add-ons. Introducing RUs may lead to a 40% increase in multi-threaded performance over Meteor Lake at similar core counts.

Cache Boost and Architecture Changes

Arrow Lake is rumored to see an L2 cache increase to 3MB for its Lion Cove P-cores, a 50% bump compared to Raptor Cove. This alone can offer substantial single-threaded performance improvements. However, we might see more profound architectural changes beyond the cache upgrade.

Cooling Compatibility Concerns

The good news on performance is tempered by potential issues with cooler compatibility for Intel's 15th Gen Arrow Lake CPUs. Igor's Lab hints that changes in CPU Z-height may render existing coolers incompatible, mirroring issues faced with 12th Gen CPUs. More information on this change is eagerly awaited.

The Performance Promise

Benchmark results hint at an impressive performance increase, potentially up to 21% over the current Core i9-13900K in multi-threaded tests. Even the 14th Gen Raptor Lake refresh CPUs show a slight increase, although it's mostly a refresh of the existing architecture.

Beyond Arrow Lake: Lunar, Panther, and Diamond Rapids

Following Arrow Lake, The next Intel family will succeed with a 4 + 4 core configuration in the first half of 2025, forming the basis of Lunar Lake. The Data Center side also has some exciting developments, with Diamond Rapids succeeding Granite Rapids and boasting up to 192 cores based on Lion Cove+ P-core architecture.


Intel's Arrow Lake has set the tech community abuzz with its ambitious features and performance promises. As we approach the launch, the rumors pile up, painting an exciting picture of what's to come. However, the anticipation is tinged with uncertainty with potential changes in cooler compatibility and other yet-to-be-revealed details

Titan Computers USA will be watching closely as the story of Arrow Lake unfolds, ready to offer these cutting-edge processors to our tech-savvy customers. Stay tuned for more updates as we learn what could be a landmark release in CPUs.
