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

Head-to-Head Benchmarks

The head-to-head results are decisively lopsided. The Intel Core Ultra 5 245K wins 16 of the 17 recorded comparisons, while the Intel Core i7-14701E manages a single victory. The average benchmark score for the Ultra 5 245K is 54053, placing it in the 91st percentile of all CPUs, while the i7-14701E averages 33206, sitting in the 83rd percentile.

The largest margin of victory for the Ultra 5 245K appears in the PassMark find prime numbers test. The Ultra 5 scores 414 against the i7-14701E's 176, a delta of -57.5 percent from the perspective of the i7-14701E. Data encryption shows a similar gap, with the Ultra 5 delivering 33286 versus 14862, a 55.4 percent deficit for the i7-14701E. Floating point math also heavily favors the newer part, 130678 to 61873, a 52.7 percent difference.

The extended instructions workload is another strong showing for the Ultra 5 245K. Its score of 37617 is 50.7 percent ahead of the i7-14701E's 18528. Random string sorting follows at 47.1 percent, with the Ultra 5 at 55098 and the i7-14701E at 29158. The Cinebench R15 multicore test shows the Ultra 5 at 3850 versus 2237, a 41.9 percent lead. Cinebench R20 multicore and PassMark multithread both show 39.3 percent gaps, with scores of 15368 versus 9321 and 43047 versus 26112, respectively.

Data compression favors the Ultra 5 245K by 38.3 percent, 458817 to 282939. The Cinebench R20 singlecore test reveals a 39.4 percent advantage for the Ultra 5, scoring 2169 against 1315. PassMark physics shows a 22.1 percent gap, 3081 to 2399. Integer math is closer, with the Ultra 5 at 98524 versus 81325, a 17.5 percent difference. Even the Cinebench R23 multicore result, which is the closest multicore comparison, still gives the Ultra 5 an 11.5 percent edge, 25066 to 22195.

The single-threaded PassMark tests are the most competitive. The Ultra 5 scores 4714, just 8.7 percent above the i7-14701E's 4305. Cinebench R15 singlecore is even tighter, with the Ultra 5 at 322 versus 315, a mere 2.2 percent gap.

The one test the i7-14701E wins is Cinebench R23 singlecore. There, the older chip scores 3133 against the Ultra 5's 2132, a substantial 47 percent advantage. This is an anomaly within the wider single-core picture, and it stands as the sole counterpoint to an otherwise total sweep.

Where Each One Wins

The workload split is clear from the recorded data. The Intel Core Ultra 5 245K dominates every multithreaded and throughput-oriented workload in the database. Its wins span compression, encryption, extended instruction sets, prime number generation, floating point math, integer math, physics simulation, and random string sorting. The margins in these tests range from 11.5 percent to 57.5 percent, indicating a broad and consistent advantage in compute-heavy tasks.

The Ultra 5 245K also wins the majority of single-threaded tests, including Cinebench R15 singlecore and PassMark single thread. However, the margins there are smaller, suggesting that the architectural differences matter less in lightly threaded scenarios.

The Intel Core i7-14701E has a narrow but meaningful claim in one specific area: Cinebench R23 singlecore. Its 3133 score is far above the Ultra 5's 2132, and this 47 percent lead is the largest margin in either direction across all tests. This suggests that for workloads that stress a single core in a manner similar to Cinebench R23, the i7-14701E retains a significant advantage.

The data also shows a difference in overall positioning. The Ultra 5 245K sits at the 91st percentile, and its nearest rivals include the Intel Core i7-14700F with a delta of 0.8 percent and the AMD Ryzen 9 9900X3D at -1.3 percent. The i7-14701E, by contrast, sits at the 83rd percentile with rivals such as the AMD Ryzen 9 PRO 6950H at a 0 percent delta and the Intel Core i7-13650HX at 0.4 percent.

Architecture Differences

The two processors come from different design eras. The i7-14701E uses the Raptor Lake architecture on a 10 nm process node built by Intel. It has 8 cores and 16 threads, with a base clock of 2.60 GHz and a boost clock of 5.40 GHz. The Ultra 5 245K uses the Arrow Lake architecture on a 3 nm node built by TSMC. It has 14 cores and 14 threads, with a base clock of 4.20 GHz and a boost clock of 5.20 GHz. The transistor count for the Ultra 5 is listed as 17,800 million, while the i7-14701E does not have a recorded transistor count.

Cache hierarchies differ substantially. The i7-14701E has 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3 cache. The Ultra 5 245K has 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3 cache. Despite having fewer cores, the i7-14701E carries a larger L3 pool, while the Ultra 5 compensates with larger per-core L1 and L2 allocations.

Memory support also diverges. The i7-14701E supports both DDR4 and DDR5 memory, while the Ultra 5 245K supports only DDR5. Both use dual-channel memory buses. The Ultra 5 has a recorded memory bandwidth of 102.4 GB/s, while the i7-14701E does not have a listed bandwidth figure. Both processors support ECC memory.

The sockets are incompatible. The i7-14701E uses Intel Socket 1700, while the Ultra 5 245K uses Intel Socket 1851. PCIe support differs as well: the i7-14701E provides Gen 5 with 16 lanes from the CPU, while the Ultra 5 provides Gen 5 with 20 lanes.

Integrated graphics present another contrast. The i7-14701E includes UHD Graphics 770, while the Ultra 5 245K uses Arc Xe-LPG Graphics 64EU. The i7-14701E is not multiplier unlocked, whereas the Ultra 5 245K is. The power envelope also differs, with the i7-14701E at a 65 TDP and the Ultra 5 at 125 TDP.

The Verdict

The recorded data points to a clear overall winner in the Intel Core Ultra 5 245K. It wins 16 of 17 head-to-head comparisons, holds a 63 percent higher average benchmark score, and sits 8 percentile points higher in the global ranking. Its advantages in compression, encryption, and floating point math are substantial, with margins exceeding 50 percent in several tests. The Ultra 5 245K also carries a launch MSRP of $319, and its nearest rivals in the database include the Intel Core i7-14700F and the AMD Ryzen 9 9900X3D.

The Intel Core i7-14701E is not without merit. Its Cinebench R23 singlecore score of 3133 is exceptional, and its 65 TDP is considerably lower than the Ultra 5's 125 TDP. The i7-14701E also supports DDR4 memory, which may matter for systems that are not ready to move to DDR5. Its socket is Intel Socket 1700, whereas the Ultra 5 requires the newer Intel Socket 1851.

For users whose workloads resemble Cinebench R23 singlecore, the i7-14701E is the better choice based on the data. For everything else, the Ultra 5 245K shows a decisive advantage. The multithreaded and throughput-oriented tests all favor the Ultra 5, and even its single-threaded PassMark result is ahead. The i7-14701E's lower power draw and DDR4 support are notable, but the performance gap in the benchmark suite is too wide to ignore.
