Intel Core 7 253PQE vs Intel Core i5-14450HX Comparison

The Intel Core 7 253PQE and the Intel Core i5-14450HX are both 10-core Intel processors, but they target different segments and deliver vastly different performance profiles. The recorded data shows a decisive sweep, with the Core 7 253PQE winning all 17 head-to-head benchmark comparisons against the Core i5-14450HX. The average benchmark score for the Core 7 253PQE is 55919, placing it in the 91st percentile of all CPUs, while the Core i5-14450HX averages 32040, landing in the 82nd percentile. This gap in average scores, roughly 75%, reflects a fundamental difference in positioning, with the desktop-focused Core 7 part operating in a higher performance tier than the mobile-oriented Core i5.

Where Each One Wins

The benchmark data is unambiguous: the Intel Core 7 253PQE wins every recorded test. There are no workload categories where the Core i5-14450HX takes a victory, so the use-case split is defined by the scale of the Core 7's advantage rather than by any reversal of fortune. For single-threaded responsiveness, the Core 7 253PQE leads the PassMark single-thread test with a score of 4389 against 3643 for the Core i5, a 20.5% advantage. This edge extends to Cinebench single-core workloads, where the Core 7 posts 4431 in R23 single-core versus 2838 for the i5, a 56.1% gap. Applications that rely on one or two threads, such as lightweight productivity tasks or general system navigation, will favor the Core 7 part.

In multi-threaded and heavily parallel workloads, the Core 7 253PQE widens its lead considerably. The PassMark multithread score of 41656 is 75.9% higher than the Core i5's 23680. The Cinebench R23 multi-core test shows a similar pattern, with the Core 7 scoring 31390 against 20108, a 56.1% difference. The largest deltas appear in compute-heavy operations like prime number finding and physics simulation. The Core 7 253PQE scores 206 in PassMark find prime numbers, which is 110.2% ahead of the Core i5's 98, and 2970 in PassMark physics, a 101.4% margin over 1475. The Core 7 also dominates extended instruction workloads, scoring 32390 in PassMark extended instructions, 88.2% above the i5's 17207. For floating-point math, the Core 7 delivers 105279 versus 58037, an 81.4% lead, and for integer math it posts 137795 against 78330, a 75.9% advantage.

Architecture Differences

The two processors share the same Intel foundry and 10 nm process node, but their underlying designs diverge in several key areas. The Core 7 253PQE uses the Bartlett Lake codename and belongs to the Core 7 generation, while the Core i5-14450HX is based on Raptor Lake, specifically the Raptor Lake-HX refresh, and belongs to the Core 14th Gen series. Both chips feature 10 cores, but the Core 7 253PQE supports 20 threads, whereas the Core i5-14450HX supports 16 threads. This thread count difference is central to the multi-core performance gap, as the Core 7 can process more concurrent work items.

Cache configurations also differ significantly. Both processors provide 80 KB of L1 cache per core and 2 MB of L2 cache per core, but the shared L3 cache is much larger on the Core 7 253PQE, which has 33 MB shared L3, compared to 20 MB shared L3 on the Core i5-14450HX. The larger L3 pool on the Core 7 gives it more room for frequently accessed data, which contributes to its superior performance in cache-sensitive workloads. Clock speeds further separate the two. The Core 7 253PQE has a base clock of 3.50 GHz and a boost clock of 5.70 GHz, while the Core i5-14450HX operates at a 2.40 GHz base and 4.80 GHz boost. The higher clocks on the Core 7 directly support its lead in both single-core and multi-core tests.

The processors also differ in their physical design and market positioning. The Core 7 253PQE uses Intel Socket 1700 and is classified as a desktop part, while the Core i5-14450HX uses Intel BGA 1964 and is a mobile processor. The Core 7 has a TDP of 125, while the Core i5 has a TDP of 55, reflecting the desktop part's higher power envelope and the mobile part's focus on efficiency. The die size for the Core i5-14450HX is recorded as 257 mm², while no die size is listed for the Core 7 253PQE. The Core 7 253PQE integrates UHD Graphics 770, whereas the Core i5-14450HX uses UHD Graphics 710. Both support DDR4 and DDR5 memory with dual-channel buses, and both support ECC memory. The Core 7 253PQE records a memory bandwidth of 89.6 GB/s, while no memory bandwidth figure is listed for the Core i5-14450HX. Both processors offer PCIe Gen 5 with 16 lanes from the CPU. The Core 7 253PQE has a locked multiplier, while the Core i5-14450HX has an unlocked multiplier, though the mobile socket limits practical overclocking. The Core 7 253PQE launched on March 8, 2026, with a launch MSRP of $409, while the Core i5-14450HX launched on January 7, 2024, with no launch MSRP recorded.

These nearest-rival groupings confirm that the Core 7 253PQE competes in a much higher performance class than the Core i5-14450HX.

The Verdict

The recorded data directs a clear choice based on workload and platform. The Core 7 253PQE is the stronger processor in every measured category, with its largest advantages in prime number finding, physics, and extended instructions, where it leads by roughly 100% or more. It also holds a substantial lead in multithreaded performance, with a 75.9% advantage in PassMark multithread and a 56.1% advantage in Cinebench R23 multi-core. For users running heavily threaded applications, rendering tasks, or data-intensive workloads, the Core 7 253PQE is the obvious pick, provided the desktop Socket 1700 platform and 125 TDP are acceptable.

The Core i5-14450HX, despite losing every head-to-head test, remains a distinct product because of its mobile BGA 1964 socket and 55 TDP. Its nearest rivals include the Intel Core i7-13705H and the Intel Core i5-14400, and it sits in the 82nd percentile of all CPUs. For systems that require a mobile form factor, the Core i5-14450HX is the only one of the two that fits, since the Core 7 253PQE is a desktop part. The Core i5's unlocked multiplier adds flexibility, though the mobile socket limits its practical range. The data does not show any scenario where the Core i5-14450HX outperforms the Core 7 253PQE, so the choice rests on platform compatibility: desktop users get the far faster Core 7 253PQE, while mobile users get the Core i5-14450HX with its lower power draw and integrated UHD Graphics 710.
