Intel Core i7-14650HX vs Intel Core i7-14701E Comparison

The Verdict

The benchmark data splits these two Intel Core i7 processors into clearly different roles. The Intel Core i7-14650HX wins 10 of 17 head-to-head tests, while the Intel Core i7-14701E wins 7. The mobile part, the 14650HX, dominates in multithreaded throughput and data-heavy workloads, with its average benchmark score of 41576 placing it in the 88th percentile of all CPUs. The desktop part, the 14701E, counters with superior single-thread performance and a higher average score in specific Cinebench iterations, though its overall average of 33206 lands in the 83rd percentile. The 14650HX is for workloads that scale across many cores: rendering, compression, encryption, and floating point math. The 14701E is for single-thread-sensitive tasks where clock speed and per-core efficiency matter more. The data does not support a universal winner; it supports a workload-dependent choice.

Architecture Differences

Both processors share the same Raptor Lake architecture family and are built on Intel's 10 nm process node with a 257 mm² die size. The 14650HX uses the Raptor Lake-HX codename and targets the mobile segment with an Intel BGA 1964 socket, while the 14701E uses the Raptor Lake-R codename, targets desktops, and fits Intel Socket 1700. The core counts diverge sharply: the 14650HX has 16 cores and 24 threads, the 14701E has 8 cores and 16 threads. Both use 80 KB of L1 cache per core and 2 MB of L2 cache per core, but shared L3 cache differs, with 30 MB on the 14650HX and 33 MB on the 14701E.

Clock behavior also separates them. The 14650HX runs a 2.20 GHz base clock and 5.20 GHz boost clock, while the 14701E runs a 2.60 GHz base and 5.40 GHz boost. The desktop part has a higher TDP of 65 compared to the mobile part's 55. Both support DDR4 and DDR5 memory over dual channels, both have ECC memory support, and both provide Gen 5 PCIe with 16 CPU lanes. Integrated graphics differ: UHD Graphics 710 on the 14650HX versus UHD Graphics 770 on the 14701E. The multiplier is unlocked on the mobile part but locked on the desktop part. Release dates place the 14650HX in January 2024 and the 14701E in June 2024.

Where Each One Wins

The 14650HX wins every multicore-heavy comparison in the recorded data. Cinebench R15 multicore goes to it by 55.1%, Cinebench R20 multicore by 28.2%, and PassMark multithread by 28.3%. Data compression shows a 40.8% lead, data encryption a 54.2% lead, extended instructions a 30.3% lead, floating point math a 37.4% lead, integer math a 43.5% lead, and random string sorting a 47.6% lead. These results indicate a processor designed for parallel throughput, where its 16 cores and 24 threads can be fully utilized.

The 14701E wins the single-thread and lightly threaded tests. Cinebench R15 singlecore goes to it by 9.4%, Cinebench R23 singlecore by 37.2%, PassMark single thread by 10.8%, PassMark find prime numbers by 13.6%, and PassMark physics by 8.2%. Cinebench R23 multicore also goes to the 14701E by 7.8%, which is notable given its 8-core count. The desktop part's higher boost clock of 5.40 GHz appears to translate directly into wins where per-core speed dominates.

Head-to-Head Benchmarks

The largest win for the 14650HX comes in Cinebench R15 multicore, where it scores 3470.5 against 2237 for the 14701E, a 55.1% margin. Data encryption follows closely with a 54.2% lead (22917 versus 14862). Random string sorting shows a 47.6% gap (43035 versus 29158), and integer math shows 43.5% (116661 versus 81325). Data compression delivers 40.8% (398418 versus 282939), floating point math 37.4% (84999 versus 61873), and extended instructions 30.3% (24150 versus 18528). Cinebench R20 multicore and PassMark multithread both land near 28% (11946 versus 9321 and 33495 versus 26112 respectively). These margins all point in the same direction: the 14650HX has substantial parallel headroom.

The 14701E counters most decisively in Cinebench R23 singlecore, scoring 3133 against 1969, a 37.2% advantage. Cinebench R23 multicore also favors it at 22195 versus 20454, a 7.8% lead. PassMark single thread shows 4305 versus 3841, a 10.8% margin. Cinebench R15 singlecore goes 315 versus 285.5, a 9.4% lead. PassMark find prime numbers favors it 176 versus 152, a 13.6% margin, and PassMark physics favors it 2399 versus 2202, an 8.2% margin. The 14701E's single-thread wins are consistent, and its Cinebench R23 multicore result suggests that its larger L3 cache and higher clocks can compensate for fewer cores in certain rendering workloads.

The single-thread results deserve extra scrutiny. The 14701E wins Cinebench R23 singlecore by 37.2%, yet its Cinebench R20 singlecore score is 1315 versus 1686 for the 14650HX, a 28.2% loss. That reversal between two Cinebench versions is unusual. The R20 result contradicts the R23 result, and the R15 singlecore test also favors the 14701E but only by 9.4%. The data records these conflicting outcomes without a clear explanation, which suggests that workload-specific scaling behavior differs between the two processors.

PassMark single thread and PassMark singlethread appear as duplicate entries with identical scores (3841 for the 14650HX, 4305 for the 14701E), confirming the 10.8% single-thread advantage for the desktop part. The 14650HX wins 10 tests overall, but the distribution of wins is lopsided: its victories are mostly in throughput tests, while the 14701E's victories cluster in single-thread tests and physics.
