Intel Core Ultra 7 265K
A 20-core (8P+12E) Arrow Lake-S chip for Intel's new LGA1851 socket, boosting to 5.5 GHz with 66 MB of combined cache. Positioned as the mid-flagship pick for buyers who want most of the multithreaded performance of the Ultra 9 285K with a lower price and turbo-power ceiling.
Pros
- 20 cores (8P+12E) for strong multithreaded performance at a mid-flagship price
- 66 MB of combined cache (36 MB L2 + 30 MB L3)
- Native DDR5-6400 support and full PCIe 5.0 connectivity
- Unlocked multiplier for overclocking on Z890 boards
- In review testing it posted a Cinebench R23 multi-core score competitive with much pricier previous-generation chips
Cons
- No cooler included, and the 250 W turbo power still needs a capable cooler
- Requires a new LGA1851 motherboard; no backward compatibility with older Intel boards
- No Hyper-Threading, so its 20 threads trail some previous-generation chips with more logical cores
- Gaming performance in review testing did not clearly improve over the previous generation
Excellent
