Intel Core i7-14701E vs Intel Core Ultra 5 245 Comparison

Head-to-Head Benchmarks

The benchmark data delivers a decisive outcome: the Intel Core Ultra 5 245 wins all 17 recorded comparisons against the Intel Core i7-14701E. There are no contested results, no narrow defeats, and no categories where the older Core i7 part manages to pull ahead. The widest margins appear in encryption and prime number workloads, while the narrowest gap shows up in single-threaded PassMark testing.

The largest single delta is in PassMark find prime numbers, where the Core Ultra 5 245 scores 365 versus 176 for the Core i7-14701E, a 51.8% advantage. Data encryption follows closely at 50.8%: 30236 against 14862. Extended instructions show a 44.4% gap (33304 versus 18528), and random string sorting trails at 40.7% (49140 versus 29158). Floating point math delivers a 48.7% difference (120548 versus 61873). These are not marginal improvements; they represent substantial execution efficiency gains in compute-heavy operations.

In Cinebench tests, the Core Ultra 5 245 consistently leads by roughly 32.6% across every variant. R15 multicore shows 3318 versus 2237, R20 multicore shows 13828 versus 9321, and R23 multicore shows 32924 versus 22195. Single-core Cinebench results mirror the same pattern: R15 single-core 468 versus 315, R20 single-core 1952 versus 1315, and R23 single-core 4648 versus 3133. The consistency of the 32.6% delta across all six Cinebench tests indicates a uniform architectural advantage rather than workload-specific tuning.

PassMark multithread scoring shows a 32.5% lead for the Core Ultra 5 245 (38706 versus 26112). Integer math is the closest multi-threaded comparison at 10.8% (91187 versus 81325), and physics is nearly as tight at 6.6% (2569 versus 2399). The smallest overall delta is PassMark single-thread at 2% (4394 versus 4305), meaning the Core i7-14701E remains competitive in lightly threaded scenarios despite losing everywhere else.

The average benchmark score reinforces the hierarchy: the Core Ultra 5 245 sits at 48995, while the Core i7-14701E averages 33206. That difference places the Core Ultra 5 245 in the 90th percentile of all CPUs, whereas the Core i7-14701E ranks in the 83rd percentile. Neither processor falls into a low tier, but the Core Ultra 5 245 operates in a higher performance bracket overall.

Where Each One Wins

The Intel Core i7-14701E does not register a single benchmark win in the recorded data. Its only relative strength appears in PassMark single-thread, where the 2% gap (4305 versus 4394) suggests that workloads dominated by light single-threaded execution will see near-parity performance. Similarly, PassMark physics at 6.6% and integer math at 10.8% are the smallest deltas, indicating that certain integer-heavy tasks may not feel dramatically different in practice.

The Intel Core Ultra 5 245 wins everywhere else, with its largest advantages in encryption, prime number generation, extended instruction sets, and floating point math. These are precisely the workloads that benefit from newer microarchitecture, wider execution resources, and higher per-core efficiency. Data compression (400942 versus 282939, a 29.4% gap) and random string sorting (49140 versus 29158) also favor the Core Ultra 5 245 by wide margins.

For users running Cinebench-style rendering workloads, the Core Ultra 5 245 delivers a consistent one-third performance uplift. For users running PassMark's mixed workload suite, the Core Ultra 5 245 leads in every category, with the smallest edge in single-threaded performance. The Core i7-14701E, while not competitive in this comparison, does keep pace in the narrow single-thread metric, which may matter for older or poorly threaded applications.

Architecture Differences

The two processors come from different Intel generations built on different process nodes. The Core i7-14701E uses Raptor Lake architecture (Raptor Lake-R codename) on Intel's 10 nm process, fabricated by Intel with a die size of 257 mm². The Core Ultra 5 245 uses Arrow Lake architecture (Arrow Lake-S codename) on a 3 nm process, fabricated by TSMC with a die size of 243 mm². The Core Ultra 5 245 also carries a transistor count of 17,800 million, a figure not listed for the Core i7-14701E.

Core and thread counts differ notably. The Core i7-14701E provides 8 cores and 16 threads, while the Core Ultra 5 245 provides 14 cores and 14 threads. The Core Ultra 5 245 has more physical cores but no hyper-threading, whereas the Core i7-14701E relies on hyper-threading to reach 16 threads from 8 cores. This explains why the Core Ultra 5 245 leads in multithreaded benchmarks despite having fewer threads: 14 full cores outperform 8 cores with 16 logical threads in the tested workloads.

Cache configurations also diverge. The Core i7-14701E has 80 KB L1 per core, 2 MB L2 per core, and 33 MB shared L3. The Core Ultra 5 245 has 192 KB L1 per core, 3 MB L2 per core, and 24 MB shared L3. The Core Ultra 5 245 provides more per-core cache but less total L3. Clock speeds differ as well: the Core i7-14701E bases at 2.60 GHz and boosts to 5.40 GHz, while the Core Ultra 5 245 bases at 3.50 GHz and boosts to 5.10 GHz. The Core i7-14701E has a higher boost clock, yet the Core Ultra 5 245 still wins all single-threaded tests, indicating that IPC gains from the newer architecture outweigh the 0.30 GHz clock deficit.

Memory support separates the two clearly. The Core i7-14701E supports both DDR4 and DDR5 over a dual-channel bus, while the Core Ultra 5 245 supports only DDR5. The Core Ultra 5 245 lists a memory bandwidth of 102.4 GB/s; no bandwidth figure is recorded for the Core i7-14701E. Both support ECC memory. PCIe lanes differ: the Core i7-14701E provides Gen 5 with 16 lanes (CPU only), while the Core Ultra 5 245 provides Gen 5 with 20 lanes (CPU only).

Sockets are incompatible. The Core i7-14701E uses Intel Socket 1700, and the Core Ultra 5 245 uses Intel Socket 1851. Integrated graphics also change: the Core i7-14701E uses UHD Graphics 770, while the Core Ultra 5 245 uses Arc Xe-LPG Graphics 64EU. Neither processor has an unlocked multiplier. The Core i7-14701E released on 2024-06-30, and the Core Ultra 5 245 released on 2025-01-06.

The Verdict

The Intel Core Ultra 5 245 is the clear performance leader in every measured category. Its 90th percentile ranking versus the 83rd percentile for the Core i7-14701E confirms a higher overall standing in the database. The average benchmark score of 48995 for the Core Ultra 5 245 versus 33206 for the Core i7-14701E leaves no ambiguity about which part delivers more compute throughput.

Users selecting between these two should base the decision on platform requirements and workload timing. The Core Ultra 5 245 offers 14 physical cores, newer 3 nm process technology from TSMC, higher memory bandwidth at 102.4 GB/s, and a larger PCIe lane count of 20. The Core i7-14701E counters with 16 threads, a higher boost clock of 5.40 GHz, support for DDR4 memory, and a larger 33 MB L3 cache, but these features do not translate into any benchmark victory.

The Core Ultra 5 245 also carries a launch MSRP of $270. The Core i7-14701E has no recorded launch MSRP in the database. Both processors target the desktop market, both remain in active production, and neither offers an unlocked multiplier.

For any workload represented in the recorded benchmarks, the Intel Core Ultra 5 245 is the superior choice. The only scenario where the Core i7-14701E approaches parity is in PassMark single-thread performance, where the 2% gap may be imperceptible. That single metric does not offset the 32.6% Cinebench deficits, the 50.8% encryption gap, or the 48.7% floating point shortfall. The data supports one conclusion: the Core Ultra 5 245 outperforms the Core i7-14701E across the board.
