Intel Core i7-14700T vs Intel Core Ultra X7 358H Comparison

Head-to-Head Benchmarks

The benchmark data presents a genuinely split personality. The Intel Core i7-14700T and the Intel Core Ultra X7 358H each claim victory in distinct categories, and the margins are often dramatic. The overall win count favors the Ultra X7 358H, which takes 12 of the 17 recorded head-to-head tests, but the i7-14700T secures the most decisive single victories.

Starting with the most lopsided result in the entire comparison: in Cinebench R23 single-core, the i7-14700T scores 3667 against the Ultra X7 358H's 2080, a 76.3% advantage. That is not a marginal edge; it is a generational gap in the other direction. The same pattern appears in Cinebench R23 multi-core, where the i7-14700T posts 25980 versus 18747, a 38.6% lead. These two tests alone define the i7-14700T as the champion of prolonged, heavily threaded rendering workloads.

However, the Ultra X7 358H strikes back in the other Cinebench versions. In Cinebench R15 multi-core, it scores 3027 against 2618, a 13.5% advantage. In Cinebench R20 multi-core, it leads 12011 to 10911, a 9.2% margin. Even in Cinebench R20 single-core, the Ultra X7 358H wins 1695 to 1540, a 9.1% edge. This creates a confusing picture: the newer mobile chip wins in older Cinebench versions, while the desktop chip dominates the newer R23 release. The likely explanation lies in workload scaling differences, but the recorded data speaks for itself.

The Passmark suite reinforces the split. The Ultra X7 358H wins heavily in several specialized workloads: data encryption at 26046 versus 21277, an 18.3% lead; extended instructions at 27274 versus 20052, a 26.5% lead; find prime numbers at 337 versus 145, a staggering 57% lead; floating point math at 103842 versus 79042, a 23.9% lead; and physics at 3021 versus 1946, a 35.6% lead. It also takes passmark multithread with 33802 against 30571, a 9.6% margin, plus random string sorting at 40357 versus 38546, a 4.5% edge, and single-thread at 4124 versus 3905, a 5.3% lead.

The i7-14700T answers with integer math: 113854 versus 83147, a 36.9% advantage, and data compression at 354216 versus 332508, a 6.5% lead. Its Cinebench R23 results remain its strongest statement, but the Ultra X7 358H clearly owns the broader Passmark landscape. The average benchmark scores tell a similar story: the i7-14700T averages 41914, while the Ultra X7 358H averages 40967, a difference of less than one percent. The i7-14700T sits at the 88th percentile of all CPUs, the Ultra X7 358H at the 87th. These are near-identical overall positions, with the nearest rivals of the i7-14700T including the AMD Ryzen 9 PRO 8945HS at a 0.1% deficit and the Intel Core i7-12850HX at a 0.3% surplus. The Ultra X7 358H's closest competitor is the Intel Core Ultra 7 366H, which sits 0.7% ahead.

Architecture Differences

The architectural gap between these two is vast. The i7-14700T belongs to the Raptor Lake Refresh generation, built on Intel's 10 nm process with a die size of 257 mm². It houses 20 cores and 28 threads, with a base clock of 1.30 GHz and a boost clock of 5.20 GHz. Its cache hierarchy consists of 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3 cache. It supports both DDR4 and DDR5 memory across a dual-channel bus, includes ECC memory support, and offers PCIe Gen 5 with 16 lanes from the CPU. Its integrated graphics are UHD Graphics 770. The socket is Intel Socket 1700, and it is a desktop part with a launch MSRP of $384.

The Ultra X7 358H is a fundamentally different design. It is a Panther Lake-H mobile processor built on Intel's 3 nm process, with 16 cores and 16 threads. Base clock is 1.90 GHz, boost clock is 4.80 GHz. Its cache configuration is notably different: 192 KB of L1 per core, 3 MB of L2 per core, and only 18 MB of shared L3. It supports only LPDDR5X memory, dual-channel, with a memory bandwidth of 153.6 GB/s. There is no ECC support. PCIe is Gen 5 but limited to 4 lanes from the CPU. Integrated graphics come as the Arc B390. The socket is Intel BGA 2540, and it targets the mobile segment. The process node difference is stark: 10 nm versus 3 nm, which explains some of the efficiency and per-core behavior differences in the benchmarks.

The core count and thread count disparity matters. The i7-14700T has 20 cores and 28 threads, giving it substantial thread count advantage. The Ultra X7 358H has 16 cores and 16 threads, meaning no hyperthreading. That explains why the i7-14700T wins in Cinebench R23 multi-core, a test that scales aggressively with thread count. Yet the Ultra X7 358H wins in Cinebench R15 and R20 multi-core, which suggests those workloads favor its higher base clock and newer architecture per-core efficiency. The L3 cache difference is also telling: 33 MB shared on the i7-14700T versus 18 MB shared on the Ultra X7 358H. Larger cache helps in some workloads, but the Ultra X7 358H's per-core L1 and L2 are larger, which may aid its single-thread and specialized math results.

The Verdict

The data points to two very different usage profiles. The i7-14700T is the clear choice for multi-threaded rendering workloads that resemble Cinebench R23, where it holds a 38.6% lead over the Ultra X7 358H. Its 28 threads and 33 MB of L3 cache deliver exceptional throughput in integer math, where it leads by 36.9%, and in data compression, where it leads by 6.5%. It also completely dominates in single-core Cinebench R23, leading by 76.3%, which suggests its boost clock of 5.20 GHz provides a significant advantage in lightly threaded tasks that scale with raw clock speed.

The Ultra X7 358H, on the other hand, wins the majority of the head-to-head tests. Its 3 nm process and newer Panther Lake architecture deliver superior results in floating point math, encryption, extended instructions, prime number finding, and physics simulations. It leads by 57% in find prime numbers and by 35.6% in physics, which are workloads that benefit from architectural efficiency rather than raw thread count. It also wins in single-thread Passmark with 4124 versus 3905, a 5.3% margin, and in multithread Passmark with 33802 versus 30571, a 9.6% margin.

For a desktop user prioritizing heavy rendering and classic multi-core throughput, the i7-14700T is the data-backed pick. For a mobile user needing broad workload versatility, especially in scientific or encryption-heavy tasks, the Ultra X7 358H is the better fit. The overall average benchmark scores are nearly identical, so the choice hinges on which specific workloads matter most.

Where Each One Wins

The i7-14700T wins in Cinebench R23 multi-core, Cinebench R23 single-core, Cinebench R15 single-core, Passmark data compression, and Passmark integer math. These are workloads that reward high thread counts, high boost clocks, and large shared caches. The 28 threads and 5.20 GHz boost clock make it the stronger choice for video rendering, code compilation, and any task that can saturate many threads simultaneously.

The Ultra X7 358H wins in Cinebench R15 multi-core, Cinebench R20 multi-core, Cinebench R20 single-core, Passmark data encryption, extended instructions, find prime numbers, floating point math, multithread, physics, random string sorting, and single-thread. That is a broad sweep across scientific computing, cryptography, and simulation workloads. Its 3 nm process, larger per-core L1 and L2 caches, and higher base clock of 1.90 GHz contribute to its dominance in these areas. The 153.6 GB/s memory bandwidth also supports memory-intensive tasks, a figure not recorded for the i7-14700T.

The takeaway: choose the i7-14700T for heavy rendering and integer-heavy desktop workloads, choose the Ultra X7 358H for mobile systems running diverse, efficiency-sensitive tasks.
