Overview
Performance and efficiency cores share this processor, with the efficiency cores handling background tasks. It fits the newest Intel socket on current series boards and supports DDR5 memory and fast PCIe.
Gamers and creators building a new rig get a high core count and a high boost clock. The listing confuses the core count in places, and no cooler is described. A board and memory are separate purchases.
Who it's for
A builder pairing a current Intel board with DDR5 memory for gaming and content work. The base power figure calls for a good cooler. Owners of older sockets should tally the full platform first.
Pros and cons
- High core count
- Fast boost clock
- PCIe 5.0 and DDR5 support
- Three year warranty
- Core count stated two ways
- Cooler not described
- Needs a new motherboard
- High base power
Performance notes
Performance cores take heavy threads such as games, while efficiency cores take background work, so total throughput rises without more heat per core. The boost clock applies to a few cores at a time and depends on cooling. Memory speed and the graphics card shape final game results.
