Head-to-Head Benchmarks

Since the head-to-head benchmark field is empty and the Core 5 223PQE has no benchmark entries, a direct comparison is impossible. The database records 17 benchmark scores for the Core Ultra 5 245KF and zero for the Core 5 223PQE. In Cinebench R23, the Core Ultra 5 245KF achieves 36647 multi-core and 5173 single-core. In Cinebench R20, it scores 15391 multi-core and 2172 single-core. In Cinebench R15, it scores 3693 multi-core and 521 single-core. These results show a consistent multi-core advantage, which is expected given its 14 physical cores versus the Core 5 223PQE's 8 cores and 16 threads. The Core Ultra 5 245KF's thread count equals its core count, meaning it has no hyper-threading, but its higher core count and 3 nm process likely compensate.

PassMark results for the Core Ultra 5 245KF reveal specific strengths. In data compression, it scores 460123, a high figure that indicates strong memory and cache performance. In data encryption, it scores 33381, and in extended instructions, 37912. Floating point math at 131546 outpaces integer math at 98854, suggesting a design optimized for scientific and graphical workloads. Single-thread performance in PassMark is 4715, which is consistent with its Cinebench single-core scores. The Core 5 223PQE's higher boost clock of 5.50 GHz could theoretically provide a single-thread advantage, but no data supports this. The Core Ultra 5 245KF's boost clock is 5.20 GHz, and its single-core Cinebench R23 score of 5173 is a recorded data point that the Core 5 223PQE cannot match in the database.

The Core Ultra 5 245KF's nearest rivals provide context for its scores. It trails the Intel Core i9-14900HX by 1.6% (the latter scores 56004) and the Intel Core 7 253PQE by 1.5% (score 55919). It leads the AMD Ryzen 9 9900X3D by 0.6% (score 54762) and the Intel Core Ultra 5 245K by 1.9% (score 54053). These deltas are small, indicating that the Core Ultra 5 245KF competes at the high end of desktop performance.
