Intel Core i7-14701E vs Intel Core Ultra 7 270HX Plus Comparison

Head-to-Head Benchmarks

The recorded data shows a complete sweep for the Intel Core Ultra 7 270HX Plus across every benchmark in the database. The Core i7-14701E does not win a single test, with the Ultra 7 taking all 17 head-to-head comparisons. The margins vary from a modest single-digit advantage to substantial multi-core leads.

The Cinebench suite illustrates the scale of the difference. In Cinebench R15 multicore, the Ultra 7 scores 4224 against the i7-14701E's 2237, a 47% advantage. The R15 singlecore test shows a similar 47.1% gap, with scores of 596 and 315 respectively. R20 multicore continues the pattern: 17603 versus 9321, again 47% apart. The R20 singlecore result is 2485 against 1315, a 47.1% delta. R23 multicore delivers 41913 versus 22195, holding the same 47% margin. R23 singlecore shows 5917 versus 3133, a 47.1% lead.

The PassMark suite reveals where the Ultra 7 stretches its lead further. The largest single delta appears in PassMark find prime numbers, where the Ultra 7 scores 482 against 176, a 63.5% advantage. Floating point math follows closely: 163567 versus 61873, a 62.2% gap. Data encryption shows 37813 versus 14862, a 60.7% difference. Extended instructions deliver 39283 versus 18528, a 52.8% lead. Random string sorting is 60020 versus 29158, a 51.4% gap. The multithread test shows 48270 versus 26112, a 45.9% difference.

The narrower margins appear in integer-heavy workloads. PassMark integer math scores 122449 against 81325, a 33.6% lead. PassMark physics shows 3843 versus 2399, a 37.6% gap. Data compression yields 493179 against 282939, a 42.6% advantage.

The tightest contest is single-thread performance in the PassMark suite. The Ultra 7 scores 4764 against the i7-14701E's 4305, a 9.6% lead. This is the only head-to-head result below double digits. The database records two identical single-thread entries for each processor (passmark_single_thread and passmark_singlethread), both confirming the same scores and the same 9.6% delta.

The overall average benchmark scores reflect this hierarchy. The Ultra 7 averages 61834 across all tests, placing it in the 93rd percentile of all CPUs tracked. The i7-14701E averages 33206, placing it in the 83rd percentile. The nearest rivals in the database provide additional context. The Ultra 7 sits within 0.8% of the Intel Core i9-13900KF, the i9-13900K, the i9-13900T, and the Intel Xeon 636. The i7-14701E sits within 0.4% of the AMD Ryzen 9 PRO 6950H, the AMD Ryzen 5 8645HS, the AMD Ryzen 7 7745HX, and the Intel Core i7-13650HX.

Architecture Differences

The two processors come from fundamentally different design generations. The i7-14701E belongs to the Core 14th Gen series, uses Raptor Lake architecture with the Raptor Lake-R codename, and is built on Intel's 10 nm process node. The Core Ultra 7 270HX Plus belongs to the Core Ultra Series 2, uses the Arrow Lake-HX Refresh codename, and is built on TSMC's 3 nm process node with 17,800 million transistors on a 243 mm² die. The i7-14701E die is 257 mm².

Core counts differ sharply. The i7-14701E has 8 cores and 16 threads, while the Ultra 7 has 20 cores and 20 threads. This means the Ultra 7 has more physical cores but no hyper-threading, while the i7-14701E has fewer cores but each one can run two threads. The cache structures also diverge significantly. The i7-14701E has 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3. The Ultra 7 has 192 KB of L1 per core, 3 MB of L2 per core, and 30 MB of shared L3. The Ultra 7's larger per-core caches and smaller total L3 reflect a design with more cores each needing more private cache.

Clock speeds are close. The i7-14701E has a 2.60 GHz base clock and a 5.40 GHz boost clock. The Ultra 7 has a 2.40 GHz base clock and a 5.30 GHz boost clock. The i7-14701E runs slightly higher in both metrics, yet it still loses every benchmark. The power envelope favors the Ultra 7, which has a 55 W TDP versus the i7-14701E's 65 W TDP.

Memory support separates the two clearly. The i7-14701E supports both DDR4 and DDR5 in a dual-channel configuration. The Ultra 7 supports DDR5 only, also dual-channel, but with a recorded memory bandwidth of 102.4 GB/s. The i7-14701E supports ECC memory; the Ultra 7 does not.

PCIe connectivity differs as well. The i7-14701E provides Gen 5 with 16 lanes (CPU only). The Ultra 7 provides Gen 5 with 20 lanes (CPU only). The integrated graphics also differ: the i7-14701E uses UHD Graphics 770, while the Ultra 7 uses Arc Xe-LPG Graphics 64EU.

The socket and market segment further distinguish them. The i7-14701E uses Intel Socket 1700 and is a desktop part. The Ultra 7 uses Intel BGA 2114 and is a mobile part. The i7-14701E has a locked multiplier; the Ultra 7 has an unlocked multiplier. Release dates differ, with the i7-14701E released in 2024-06-30 and the Ultra 7 released in 2026-03-16. Both parts are listed as Active in production status.

The Verdict

The benchmark data points to a clear hierarchy: the Intel Core Ultra 7 270HX Plus outperforms the Intel Core i7-14701E in every recorded test. The Ultra 7's average benchmark score of 61834 places it in the 93rd percentile, while the i7-14701E's average of 33206 places it in the 83rd percentile. The Ultra 7's nearest rivals are desktop i9-class parts, including the Intel Core i9-13900KF and i9-13900K, while the i7-14701E sits alongside mid-range mobile and desktop chips such as the AMD Ryzen 7 7745HX and Intel Core i7-13650HX.

The architecture differences explain much of the gap. The Ultra 7 uses a 3 nm TSMC process with 20 physical cores and larger per-core caches, while the i7-14701E uses Intel's 10 nm process with 8 cores and hyper-threading. The Ultra 7 also delivers higher memory bandwidth at 102.4 GB/s and more PCIe lanes at 20, despite running at a lower 55 W TDP.

The i7-14701E retains advantages in specific areas. It supports ECC memory, which the Ultra 7 does not. It supports both DDR4 and DDR5, while the Ultra 7 only supports DDR5. It uses a desktop socket (Intel Socket 1700) rather than a mobile BGA package, and its base and boost clocks are marginally higher at 2.60 GHz and 5.40 GHz versus 2.40 GHz and 5.30 GHz.

For workloads that depend heavily on ECC memory or DDR4 compatibility, the i7-14701E is the only option of the two. For raw performance across every benchmark category in the database, from Cinebench rendering to PassMark encryption and floating point math, the Ultra 7 is ahead by margins ranging from 9.6% to 63.5%. The data does not show a single scenario where the i7-14701E closes the gap. The Ultra 7's unlocked multiplier and mobile form factor further differentiate it as a higher-performance, more flexible part despite its lower TDP.
