Intel Core i7-14701E vs Intel Core Ultra 7 265H Comparison

The Verdict

The benchmark data splits these two processors into clearly different roles. The Intel Core Ultra 7 265H wins 14 of 17 head-to-head tests and holds an average benchmark score of 41621, which places it in the 88th percentile of all CPUs. The Intel Core i7-14701E wins only 3 tests, with an average score of 33206 and an 83rd percentile ranking. The Ultra 7 265H is the stronger overall performer, particularly in multi-threaded workloads, encryption, and floating-point math.

However, the i7-14701E has decisive advantages in two specific Cinebench tests. It beats the Ultra 7 265H by 50.6% in Cinebench R23 single-core and by 11.3% in Cinebench R23 multi-core. These are not marginal differences. The R23 single-core result is the largest margin in the entire comparison, and it signals that the desktop chip has superior per-thread execution in that particular rendering workload.

The platform context matters. The i7-14701E is a desktop processor on Intel Socket 1700 with a 65 W TDP, while the Ultra 7 265H is a mobile processor on Intel BGA 2049 with a 28 W TDP. The mobile chip achieves its higher average score while consuming less than half the TDP. The data indicates the Ultra 7 265H delivers more performance per watt, which makes it suitable for compact or battery-powered systems. The i7-14701E remains relevant for desktop builds where the R23 workload and single-thread performance in that specific test are priorities.

The pattern is consistent. The i7-14701E wins in Cinebench R23 and R15 single-core, plus R23 multi-core. The Ultra 7 265H wins every PassMark test and the remaining Cinebench tests, including both R20 variants.

Where Each One Wins

The Intel Core Ultra 7 265H is the clear winner for general multi-threaded throughput. It leads in PassMark multithread by 23.3%, in data compression by 15.5%, and in integer math by 4.9%. Its 47.5% lead in find prime numbers and 43.3% lead in floating-point math indicate strong performance in mathematical and scientific workloads. The 42.8% advantage in data encryption and 30.9% advantage in extended instructions point to security and cryptography tasks as areas where the mobile chip is substantially faster.

The Ultra 7 265H also wins the two R20 tests and R15 multi-core, with margins between 23.2% and 25.2%. Its average benchmark score of 41621 is 25.4% higher than the i7-14701E's 33206. The 88th percentile ranking versus 83rd confirms its position in the broader CPU landscape. Its nearest rivals in the database are the Intel Core 7 251TE, the Intel Core i7-14650HX, the Intel Core i7-12850HX, and the AMD Ryzen 9 5900X, with delta percentages between -0.4% and 0.6%. This places it at parity with a group of high-end desktop and mobile processors.

The Intel Core i7-14701E wins where the workload matches its architecture. Its 50.6% lead in Cinebench R23 single-core is the standout result, and its 11.3% lead in R23 multi-core shows that it can outperform the Ultra 7 265H in that specific rendering test. The 2.6% lead in R15 single-core is smaller but still a win. Its nearest rivals are the AMD Ryzen 9 PRO 6950H, the AMD Ryzen 5 8645HS, the AMD Ryzen 7 7745HX, and the Intel Core i7-13650HX, with deltas between -0.1% and 0.4%. This group sits at a lower performance tier than the Ultra 7 265H's rivals.

The data supports a simple split. The Ultra 7 265H is the better choice for users who need broad multi-threaded performance, encryption throughput, and mathematical computation, and it achieves this with a 28 W TDP. The i7-14701E is the better choice specifically for Cinebench R23 workloads, where its single-core and multi-core scores are far ahead, and for desktop systems that require its 65 W socketed design with 16 PCIe Gen 5 lanes.
