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

Head-to-Head Benchmarks

The Intel Core Ultra 5 245T dominates the Intel Core i7-14701E across the recorded benchmark suite, taking 16 of 17 tested workloads. The only exception is PassMark physics, where the i7-14701E wins by 5.3% (2399 versus 2278). The scale of the Ultra 5 245T's victory varies widely by workload, from a narrow 1.4% edge in single-threaded tests to a commanding 45.7% margin in prime number computation.

In Cinebench testing, the Ultra 5 245T posts a consistent 15.3% advantage across all six runs. The R15 multicore result is 2641 versus 2237, R20 multicore is 11007 versus 9321, and R23 multicore is 26208 versus 22195. Single-core results follow the same pattern: R15 single-core 372 versus 315, R20 single-core 1553 versus 1315, and R23 single-core 3699 versus 3133. This uniformity suggests a fundamental throughput advantage rather than workload-specific optimization.

PassMark results reveal where the Ultra 5 245T truly separates itself. Floating point math shows a 43% lead (108499 versus 61873), while prime number finding shows a 45.7% lead (324 versus 176). Data encryption delivers a 37.2% advantage (23656 versus 14862). Extended instructions run 16.1% faster (22071 versus 18528), random string sorting is 16.5% ahead (34931 versus 29158), and multithread performance is 15.3% higher (30833 versus 26112).

Smaller gaps appear in integer math, where the Ultra 5 245T leads by 8.3% (88676 versus 81325), and data compression, where the margin shrinks to just 0.3% (283812 versus 282939). The single-thread PassMark score is nearly identical, with the Ultra 5 245T ahead by only 1.4% (4367 versus 4305).

The overall benchmark average confirms the hierarchy. The i7-14701E records an average benchmark score of 33206, placing it in the 83rd percentile of all CPUs. The Ultra 5 245T averages 38194, which sits in the 86th percentile. That is a 15% higher average score and a three-percentile jump in overall standing. The i7-14701E's closest rivals by average score are the AMD Ryzen 9 PRO 6950H at 33201 (0% delta), the AMD Ryzen 5 8645HS at 33244 (-0.1%), the AMD Ryzen 7 7745HX at 33091 (0.3%), and the Intel Core i7-13650HX at 33089 (0.4%). The Ultra 5 245T competes in a different tier, with the AMD Ryzen 7 250 at 38221 (-0.1%), Intel Core i5-14490F at 38149 (0.1%), Intel Core i5-13600HX at 38261 (-0.2%), and Intel Core i5-13600KF at 38103 (0.2%) as its nearest rivals.

Where Each One Wins

The Ultra 5 245T wins in nearly every category that stresses parallel execution or heavy arithmetic. Cinebench R23 multicore, PassMark multithread, floating point math, integer math, extended instructions, data encryption, data compression, random string sorting, and prime number finding all favor the Ultra 5 245T. Its largest margins come from floating point and prime number workloads, where the 43% and 45.7% leads respectively indicate a substantially stronger execution pipeline for mathematical operations.

Single-thread performance also belongs to the Ultra 5 245T, but the margin is thin. The 1.4% PassMark single-thread lead and the consistent 15.3% Cinebench single-core advantage show that the Ultra 5 245T is faster per thread, though the PassMark result suggests the gap narrows in certain single-threaded integer tasks.

The i7-14701E's sole victory comes in PassMark physics with a 5.3% margin. Physics simulation workloads often rely on specific instruction patterns and memory access behavior, and the recorded data indicates the i7-14701E handles this particular pattern better. Outside of that one test, there is no workload category in the database where the i7-14701E matches or exceeds the Ultra 5 245T.

The data compression result is the closest contest. At 283812 versus 282939, the Ultra 5 245T wins by only 0.3%, a margin that falls within typical run-to-run variance. For users prioritizing compression throughput specifically, the two processors are effectively equivalent according to these measurements.

Architecture Differences

The two processors come from different Intel generations built on different process nodes. The i7-14701E uses Raptor Lake architecture on a 10 nm process fabricated by Intel, with a die size of 257 mm². The Ultra 5 245T uses Arrow Lake architecture on a 3 nm process fabricated by TSMC, with a die size of 243 mm². The Ultra 5 245T also lists a transistor count of 17,800 million, while the i7-14701E has no recorded transistor count.

Core configurations differ significantly. The i7-14701E has 8 cores and 16 threads, indicating hyper-threading support. The Ultra 5 245T has 14 cores and 14 threads, meaning it offers more physical cores but no thread-doubling. This explains why the Ultra 5 245T can win multithreaded workloads despite having fewer threads than its core count might suggest relative to the i7-14701E's 16 threads.

Cache hierarchies also differ. The i7-14701E provides 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 33 MB of shared L3 cache. The Ultra 5 245T provides 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 24 MB of shared L3 cache. The Ultra 5 245T has more private cache per core but less shared L3 cache overall.

Clock speeds favor the i7-14701E on paper. Its base clock is 2.60 GHz with a boost clock of 5.40 GHz, while the Ultra 5 245T runs at 2.20 GHz base and 5.10 GHz boost. Despite the lower clocks, the Ultra 5 245T achieves higher benchmark scores, indicating that the newer architecture and larger per-core caches compensate for the frequency deficit. Both processors carry a 65 W TDP.

Memory support diverges. The i7-14701E supports both DDR4 and DDR5 over a dual-channel bus, while the Ultra 5 245T supports only DDR5 but lists a memory bandwidth of 102.4 GB/s. Both support ECC memory. The i7-14701E uses Intel Socket 1700, while the Ultra 5 245T uses Intel Socket 1851, so they are not interchangeable in existing motherboards.

PCIe connectivity differs as well. The i7-14701E provides Gen 5 with 16 lanes from the CPU. The Ultra 5 245T provides Gen 5 with 20 lanes from the CPU. Integrated graphics also differ: the i7-14701E uses UHD Graphics 770, while the Ultra 5 245T uses Arc Xe-LPG Graphics with 64 execution units.

The i7-14701E has a recorded release date of June 30, 2024, while the Ultra 5 245T was released on January 6, 2025. Neither processor has an unlocked multiplier, and both are listed as active production parts for the desktop market.

The Verdict

The benchmark data points to a clear overall winner: the Intel Core Ultra 5 245T. It wins 16 of 17 tested workloads, posts a 15% higher average benchmark score (38194 versus 33206), and ranks three percentile points higher across all CPUs (86th versus 83rd). The margin is decisive in floating point math, prime number finding, data encryption, and all Cinebench tests.

The i7-14701E retains a narrow niche in physics simulation workloads, where its 5.3% advantage over the Ultra 5 245T is the only recorded win. It also offers DDR4 memory support, which may matter for platform compatibility, and a higher boost clock of 5.40 GHz versus 5.10 GHz. However, the higher clock does not translate into higher benchmark scores in the recorded data.

For workloads dominated by parallel computation, mathematical operations, or encryption, the Ultra 5 245T is the stronger choice by a substantial margin. For physics simulation specifically, the i7-14701E holds a measurable edge. The Ultra 5 245T's launch MSRP is $270. The i7-14701E has no recorded launch MSRP.

The Ultra 5 245T also offers more CPU PCIe lanes (20 versus 16), a newer process node (3 nm versus 10 nm), a higher transistor count, and a more capable integrated GPU in Arc Xe-LPG Graphics 64EU. The i7-14701E counters with more shared L3 cache (33 MB versus 24 MB) and a larger die (257 mm² versus 243 mm²), though the larger die accompanies the older process node.
