Intel Core Ultra 7 265F vs Intel Core Ultra 7 265HX Comparison

The Intel Core Ultra 7 265F and the Intel Core Ultra 7 265HX are two 20-core processors from the same Arrow Lake family, yet they target fundamentally different platforms. The 265F is a desktop part for Socket 1851, while the 265HX is a mobile processor on BGA 2114. Despite sharing core counts and architecture, benchmark results show a clear performance hierarchy, with the desktop 265F leading in most compute-heavy tasks while the mobile 265HX counters in a few specialized workloads.

Where Each One Wins

The performance split between these two CPUs is heavily skewed toward the desktop 265F. Out of 17 head-to-head benchmark comparisons, the 265F wins 13, while the 265HX takes 4. The 265F dominates in all Cinebench tests—both single-core and multi-core across R15, R20, and R23—with a consistent 3.3% margin in every instance. It also leads in PassMark’s integer math, floating-point math, prime number finding, physics, multithreaded, and single-threaded tests. This makes the 265F the clear choice for general productivity, content creation, and any workload that relies on raw CPU throughput.

The 265HX’s wins are narrower and more specialized. It edges out the 265F in data compression (511,817 vs. 507,018, a 0.9% margin) and extended instructions (40,741 vs. 39,235, a 3.7% margin). It also ties or effectively ties in data encryption (39,472 vs. 39,468) and random string sorting (62,458 vs. 62,439). These are specific instruction-heavy or memory-latency-sensitive tasks where the mobile part’s slightly different configuration appears to help. However, the magnitude of these wins is small, and they do not offset the 265F’s broader advantages.

Architecture Differences

Both processors are built on the same Arrow Lake architecture, fabricated on TSMC’s 3 nm process node, with identical transistor counts of 17,800 million and a die size of 243 mm². The cache hierarchy is also identical: 192 KB of L1 per core, 3 MB of L2 per core, and 30 MB of shared L3. Both support DDR5 memory in a dual-channel configuration with 102.4 GB/s of bandwidth, and neither supports ECC memory. PCIe connectivity is also the same: Gen 5 with 20 lanes from the CPU.

The key architectural difference lies in the platform and packaging. The 265F uses Intel Socket 1851 with the Arrow Lake-S codename, while the 265HX uses Intel BGA 2114 with the Arrow Lake-HX codename. This reflects their intended markets: desktop vs. mobile. The 265F has a base clock of 2.40 GHz, while the 265HX has a higher base clock of 2.60 GHz, yet both boost to the same 5.30 GHz. The 265F has a TDP of 65 watts, whereas the 265HX is rated at 55 watts, despite the mobile part’s higher base clock. The 265HX also includes integrated graphics—Arc Xe-LPG Graphics 64EU—while the 265F has no integrated graphics. Additionally, the 265HX has an unlocked multiplier, while the 265F does not. The 265F has a launch MSRP of $379; the 265HX has no listed launch MSRP.

Head-to-Head Benchmarks

The most striking pattern in the head-to-head results is the uniform 3.3% lead for the 265F across all six Cinebench tests. In Cinebench R15 multi-core, the 265F scores 4,231 vs. 4,096 for the 265HX. In R15 single-core, it’s 597 vs. 578. R20 multi-core shows 17,631 vs. 17,069, and R20 single-core shows 2,488 vs. 2,409. R23 multi-core shows 41,980 vs. 40,642, and R23 single-core shows 5,926 vs. 5,737. This consistency suggests a fundamental advantage in sustained performance, likely due to the desktop platform’s ability to maintain higher power delivery over longer durations.

PassMark results tell a more nuanced story. The 265F wins integer math by 8.8% (138,078 vs. 126,954) and floating-point math by 7.6% (173,855 vs. 161,605). It also wins physics by 6.5% (3,172 vs. 2,978) and single-threaded performance by 5.6% (4,750 vs. 4,500). The multithreaded score shows a 3% lead (49,410 vs. 47,985). Prime number finding goes to the 265F by 2.5% (416 vs. 406). In contrast, the 265HX wins extended instructions by 3.7% (40,741 vs. 39,235) and data compression by 0.9% (511,817 vs. 507,018). Data encryption and random string sorting are effectively ties, with the 265HX ahead by 0.0% in both cases (39,472 vs. 39,468 and 62,458 vs. 62,439, respectively).

FAQ

Q: Which CPU is faster in multi-core workloads?

A: The Intel Core Ultra 7 265F leads in all multi-core benchmarks. It scores 41,980 in Cinebench R23 multi-core vs. 40,642 for the 265HX, a 3.3% advantage. PassMark multithreaded also favors the 265F: 49,410 vs. 47,985, a 3% lead.

Q: Are there any workloads where the 265HX outperforms the 265F?

A: Yes, but only in narrow, specific tasks. The 265HX wins in PassMark extended instructions (40,741 vs. 39,235, a 3.7% margin) and data compression (511,817 vs. 507,018, a 0.9% margin). It also ties in data encryption and random string sorting.

Q: Do both CPUs have the same core and thread counts?

A: Yes, both have 20 cores and 20 threads. They also share identical cache configurations: 192 KB L1 per core, 3 MB L2 per core, and 30 MB shared L3.

Q: What is the difference in integrated graphics?

A: The 265HX includes Arc Xe-LPG Graphics with 64 execution units. The 265F has no integrated graphics at all, meaning it requires a discrete GPU for display output.

Q: Which processor has a higher base clock?

A: The 265HX has a higher base clock of 2.60 GHz, compared to 2.40 GHz for the 265F. However, both have the same 5.30 GHz boost clock.

Q: Are these processors unlocked for overclocking?

A: Only the 265HX has an unlocked multiplier. The 265F’s multiplier is locked, preventing traditional CPU overclocking.

Specification Differences

The two processors differ in several key specifications despite sharing their core architecture. The most fundamental difference is the socket: the 265F uses Intel Socket 1851, while the 265HX uses Intel BGA 2114. This determines their platforms, with the 265F being a desktop part and the 265HX being mobile. The base clocks differ: the 265F runs at 2.40 GHz, while the 265HX runs at 2.60 GHz, though both boost to 5.30 GHz. Thermal design power also differs: the 265F is rated at 65 watts, while the 265HX is rated at 55 watts. The 265HX includes integrated graphics (Arc Xe-LPG Graphics 64EU), while the 265F has none. The 265HX has an unlocked multiplier, while the 265F does not. The 265F has a launch MSRP of $379; the 265HX has no listed launch MSRP. The release dates differ as well, with the 265F released on January 6, 2025, and the 265HX on January 12, 2025. Finally, the part numbers are distinct: SRQCV for the 265F and SRVFH for the 265HX.
