Intel Core i7-14700T vs Intel Core Ultra 5 338H Comparison

Head-to-Head Benchmarks

The recorded head-to-head data splits 10 wins for the Intel Core i7-14700T against 7 for the Intel Core Ultra 5 338H, but the margins tell a more nuanced story than the raw count suggests. The i7-14700T dominates in multi-core workloads, while the Ultra 5 338H counters with notable single-thread and specialized instruction wins.

The most decisive result appears in Cinebench R23 multi-core, where the i7-14700T scores 25,980 versus 16,331 for the Ultra 5 338H, a 59.1% advantage. That gap widens further in Cinebench R23 single-core: 3,667 against 2,044, a 79.4% lead. This is the largest delta in the entire comparison, indicating the i7-14700T's boost clock of 5.20 GHz delivers substantially higher per-core performance in this render workload than the Ultra 5 338H's 4.70 GHz peak.

Cinebench R15 and R20 results follow the same pattern, albeit with smaller margins. In R15 multi-core, the i7-14700T scores 2,618 versus 2,504, a 4.6% win. Single-core R15 shows 369 versus 305, a 21% gap. R20 multi-core lands at 10,911 versus 10,213, a 6.8% edge, while R20 single-core shows 1,540 versus 1,441, a 6.9% advantage. The consistent single-core superiority across all three Cinebench versions suggests the i7-14700T's architecture and clock strategy are better suited to these rendering tasks.

PassMark integer math delivers the second-largest delta: 113,854 versus 64,934, a 75.3% win for the i7-14700T. Data compression also favors the desktop chip at 354,216 versus 276,539, a 28.1% margin. Random string sorting goes to the i7-14700T at 38,546 versus 34,082, a 13.1% edge, and multithread overall lands at 30,571 versus 28,717, a 6.5% win.

The Ultra 5 338H, however, claims several specialized victories. The largest is find prime numbers, where it scores 304 versus 145, a 52.3% advantage. Extended instructions show 23,906 versus 20,052, a 16.1% lead. Physics simulation favors the mobile chip at 2,697 versus 1,946, a 27.8% margin. Floating point math goes to the Ultra 5 338H at 84,067 versus 79,042, a 6% edge. Single-thread PassMark shows 4,180 versus 3,905, a 6.6% win, and data encryption is essentially tied at 21,367 versus 21,277, a 0.4% edge for the Ultra 5 338H.

The average benchmark scores reflect this split: the i7-14700T averages 41,914 across all tests, placing it in the 88th percentile of all CPUs, while the Ultra 5 338H averages 33,989, sitting in the 84th percentile. The i7-14700T's nearest rival, the AMD Ryzen 9 PRO 8945HS, scores 41,963, a 0.1% difference, while the Intel Core i7-12850HX trails at 41,779, a 0.3% gap.

Architecture Differences

The two processors come from distinct architectural lines. The i7-14700T belongs to the Core 14th Gen series built on Raptor Lake, specifically the Raptor Lake-R refresh, using a 10 nm process node from Intel. It uses the Intel Socket 1700 and targets the desktop market segment. The Ultra 5 338H, by contrast, is a Panther Lake part from the Core Ultra Series 3, built on a 3 nm process node, also by Intel, but designed for mobile with an Intel BGA 2540 socket.

Core counts differ substantially. The i7-14700T packs 20 cores and 28 threads, while the Ultra 5 338H has 12 cores and 12 threads. This means the i7-14700T has no thread-doubling limitation; it offers 8 more physical cores and 16 more threads, which explains its multi-core dominance in Cinebench R23 and PassMark integer math.

Cache hierarchies also diverge. The i7-14700T uses 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3. The Ultra 5 338H uses a larger 192 KB of L1 per core and 2.5 MB of L2 per core, but only 18 MB of shared L3. The smaller L3 on the Ultra 5 338H may contribute to its lower multi-threaded rendering scores, despite having faster per-core cache.

Memory support differs by platform. The i7-14700T supports DDR4 and DDR5 memory in dual-channel configuration and includes ECC memory support. The Ultra 5 338H supports only LPDDR5X, also dual-channel, with a recorded memory bandwidth of 136.5 GB/s, and lacks ECC support. PCIe connectivity also differs: the i7-14700T provides Gen 5 with 16 lanes from the CPU, while the Ultra 5 338H provides Gen 5 with 4 lanes from the CPU.

Integrated graphics separate the two as well. The i7-14700T uses UHD Graphics 770, while the Ultra 5 338H uses Arc B370. The production status for both is Active, and both have locked multipliers, meaning neither supports unlocked overclocking.

Clock speeds show the i7-14700T with a 1.30 GHz base and 5.20 GHz boost, while the Ultra 5 338H starts higher at 1.90 GHz base but boosts lower to 4.70 GHz. The i7-14700T also carries a higher thermal design power of 35 watts versus 25 watts for the Ultra 5 338H, reflecting its desktop orientation and larger core count.

The Verdict

The benchmark data indicates two different design intents. The i7-14700T is the stronger multi-threaded processor, winning Cinebench R23 multi-core by 59.1%, integer math by 75.3%, and data compression by 28.1%. Its 20 cores and 28 threads, combined with a 5.20 GHz boost clock, deliver higher aggregate throughput in rendering and general compute workloads. The 33 MB of shared L3 cache and 16 PCIe Gen 5 lanes also position it as a desktop part capable of sustained heavy workloads.

The Ultra 5 338H counters with wins in find prime numbers (52.3% ahead), physics (27.8% ahead), extended instructions (16.1% ahead), and floating point math (6% ahead). Its higher base clock of 1.90 GHz and larger per-core L1 cache of 192 KB may explain its edge in these specialized tests. The PassMark single-thread win at 4,180 versus 3,905 shows that this mobile chip can outperform the desktop part in some latency-sensitive single-thread scenarios.

For users prioritizing multi-core rendering, the i7-14700T is the clear choice from the data. Its Cinebench R23 multi-core score of 25,980 versus 16,331 represents a substantial workload advantage. For workloads involving prime number calculations, physics simulation, or extended instruction sets, the Ultra 5 338H delivers better results despite its lower core count. The 84th percentile ranking for the Ultra 5 338H versus the 88th percentile for the i7-14700T confirms that the desktop part holds an overall edge in the recorded benchmark suite, but not universally so.

Where Each One Wins

The i7-14700T wins in all three Cinebench tests (R15, R20, R23) for both single-core and multi-core, with margins ranging from 4.6% to 79.4%. It also wins PassMark data compression by 28.1%, integer math by 75.3%, multithread by 6.5%, and random string sorting by 13.1%. These results point to workloads involving rendering, data compression, integer-heavy calculations, and general multithreaded processing.

The Ultra 5 338H wins PassMark data encryption by 0.4%, extended instructions by 16.1%, find prime numbers by 52.3%, floating point math by 6%, physics by 27.8%, and single-thread by 6.6%. These wins cluster around specialized math operations, physics simulation, and single-threaded PassMark scenarios. The encryption result is effectively a tie, but the other wins show that the Ultra 5 338H has strengths in specific computational tasks, likely tied to its newer 3 nm process node and larger per-core L1 cache.

The data suggests a workload-based split. The i7-14700T delivers its wins across a broader set of general-purpose and multithreaded benchmarks, while the Ultra 5 338H concentrates its advantages in narrower, math-intensive tests. The i7-14700T's higher average score of 41,914 and 88th percentile ranking versus the Ultra 5 338H's 33,989 and 84th percentile confirm that the desktop part is the stronger overall performer in the recorded data, even though the mobile chip wins specific niche tests.
