Intel Core 7 251TE vs Intel Core Ultra 5 236V Comparison

Where Each One Wins

The benchmark split is decisive: the Intel Core 7 251TE wins 14 of 17 head-to-head tests, while the Intel Core Ultra 5 236V takes only 3. The 251TE dominates in multi-threaded workloads, content creation, and data processing tasks, while the 236V shows strength in single-threaded integer operations and prime number calculations.

The 251TE is the clear choice for heavily parallel workloads. Its advantages are most pronounced in integer math, where it scores 224.4% higher than the 236V, and in data compression, where it leads by 89.4%. The 251TE also delivers substantial margins in encryption (69.9% ahead), floating-point math (62.2% ahead), and random string sorting (83.3% ahead). These results point to a processor built for rendering, compilation, scientific computing, and server-style workloads.

The 236V claims its wins in two specific areas: single-threaded PassMark performance (3893 versus 3568, a lead of 8.3%) and prime number finding (171 versus 140, a lead of 18.1%). These are the only tests where the mobile chip outperforms the desktop part, and both are relatively narrow margins compared to the 251TE's sweeping victories elsewhere.

In Cinebench testing, the 251TE wins every round. Its multicore margins are consistently around 63.3% across R15, R20, and R23, and its single-core margins match that figure as well. The 236V cannot close the gap in rendering tasks, even in single-threaded portions where its PassMark result suggested some advantage. The 251TE's Cinebench R23 multicore score of 25518 versus 15628 for the 236V confirms a fundamental throughput difference.

The average benchmark scores reinforce the separation: the 251TE sits at 41650, placing it in the 88th percentile of all CPUs, while the 236V averages 21952, landing in the 75th percentile. The 251TE's nearest rivals include the Core Ultra 7 265H (0.1% behind), Core i7-14650HX (0.2% behind), and Core i7-12850HX (0.3% ahead), indicating it trades blows with much larger mobile and desktop parts. The 236V, by contrast, matches the Core Ultra 5 238V (0.1% ahead), Core i7-11700F (0.2% ahead), and Ryzen 5 3600X (0.2% ahead), showing it competes with older mainstream desktop chips despite its mobile positioning.

Architecture Differences

The two processors represent fundamentally different design philosophies. The 251TE is a Bartlett Lake desktop part built on Intel's 10 nm process with a die size of 215 mm². It uses the Intel Socket 1700 platform and supports DDR4 and DDR5 memory. The 236V is a Lunar Lake mobile processor fabricated by TSMC on a 3 nm node, using the Intel BGA 2833 socket. It relies on motherboard-dependent memory support.

Core counts diverge sharply. The 251TE packs 24 cores and 32 threads, while the 236V has 8 cores and 8 threads, meaning the 251TE offers both more physical cores and simultaneous multithreading. The 251TE's base clock is 1.40 GHz with a boost clock of 5.40 GHz, versus 2.10 GHz base and 4.70 GHz boost for the 236V. The desktop chip boosts higher, though the mobile chip starts at a higher base frequency.

Cache hierarchies also differ substantially. The 251TE has 80 KB of L1 per core, 1.25 MB of L2 per core, and a shared 36 MB L3. The 236V counters with 192 KB L1 per core, 2.5 MB L2 per core, but only 8 MB of shared L3. The 251TE's much larger L3 cache supports its heavy multi-threaded workloads, while the 236V's larger per-core L1 and L2 reflect a design optimized for latency-sensitive single-thread tasks within a smaller power envelope.

Memory bandwidth differs as well. The 251TE supports dual-channel memory with 89.6 GB/s bandwidth and ECC memory, while the 236V also uses dual-channel but has no listed bandwidth figure and lacks ECC support. PCIe connectivity favors the 251TE with 16 Gen 5 lanes from the CPU, whereas the 236V provides only 4 Gen 5 lanes.

The integrated graphics also diverge. The 251TE uses UHD Graphics 770, while the 236V features Arc 130V. The 236V's newer architecture and different GPU design may serve integrated graphics workloads differently, but the CPU benchmark data does not directly measure GPU performance.

Power and market positioning separate the two clearly. The 251TE carries a 45 W TDP and targets the desktop segment, while the 236V has a 17 W TDP and targets mobile. The 251TE launched on 2025-01-12 with a launch MSRP of $384, while the 236V's launch date was 2024-09-23 with no launch MSRP recorded. Both processors have locked multipliers.

Head-to-Head Benchmarks

The largest single margin in the entire comparison belongs to the 251TE in PassMark integer math. Its score of 125739 dwarfs the 236V's 38765, a 224.4% advantage. This is not a marginal difference; it indicates a processor capable of vastly more integer operations per second, likely driven by the combination of 24 cores, 32 threads, and 36 MB of L3 cache.

Data compression shows the next biggest gap. The 251TE scores 334399 versus 176554 for the 236V, an 89.4% lead. Random string sorting follows with 39643 versus 21628, a margin of 83.3%. These results suggest the 251TE handles memory-bound and data-manipulation workloads with far greater efficiency.

Encryption performance favors the 251TE by 69.9% (22176 versus 13049). Floating-point math shows a 62.2% gap (85607 versus 52774). The Cinebench suite produces consistent 63.3% margins across all versions and both single- and multi-core tests, indicating the 251TE's architectural advantage scales uniformly in rendering tasks.

The 251TE also wins multi-threaded PassMark by 63.4% (30022 versus 18375) and physics by 28.9% (1938 versus 1503). Extended instructions show the narrowest 251TE victory at 9.9% (16974 versus 15451), suggesting the 236V's modern architecture narrows the gap on specialized instruction sets despite its lower core count.

The 236V's wins are confined to PassMark single-thread tests and prime number finding. Its single-thread score of 3893 beats the 251TE's 3568 by 8.3%, and it finds prime numbers at 171 versus 140, an 18.1% advantage. These results indicate the 236V's higher base clock and larger per-core cache can overcome the 251TE's boost clock advantage in latency-sensitive single-thread operations.

The win count tells the story: 14 victories for the 251TE, 3 for the 236V. The 236V cannot compete in throughput-oriented benchmarks, while the 251TE's only weaknesses are narrow single-thread and prime-number tests.

The Verdict

The data directs a clear choice based on workload. The Intel Core 7 251TE is the superior processor for multi-threaded, data-intensive, and rendering workloads. Its 63.3% Cinebench margins, 224.4% integer math lead, and 89.4% compression advantage make it the pick for desktop users running parallel workloads, content creation, or server-style tasks. Its 45 W TDP and 384 launch MSRP reflect a desktop part designed for sustained throughput.

The Intel Core Ultra 5 236V serves a different purpose. Its 17 W TDP and mobile BGA 2833 socket indicate a processor for thin-and-light laptops where power efficiency matters more than raw throughput. Its 8.3% single-thread PassMark lead and 18.1% prime number advantage show it can handle light single-thread tasks adequately, and its average benchmark score places it among older mainstream desktop parts like the Core i7-11700F and Ryzen 5 3600X.

For anyone building or buying a desktop system focused on rendering, compilation, data processing, or scientific computing, the 251TE wins nearly every benchmark by wide margins. For a mobile system where battery life and thermal limits are primary concerns, the 236V offers competitive single-thread performance in a much smaller power envelope. The two processors do not truly compete with each other; they serve different market segments, and the benchmark data reflects that separation.
