Intel Core 7 253PQE vs Intel Core Ultra 7 366H Comparison

Head-to-Head Benchmarks

The benchmark data shows a clear overall winner in the Intel Core 7 253PQE, which takes 15 of the 17 recorded head-to-head tests. The most decisive margin appears in PassMark integer math, where the Core 7 253PQE scores 137795 against 83695 for the Core Ultra 7 366H, a 64.6% advantage. This is the largest performance gap in the entire dataset, indicating a substantial difference in raw integer throughput between the two processors.

Data compression workloads follow a similar pattern. The Core 7 253PQE delivers 487335 in PassMark data compression, which is 48.8% ahead of the 327455 recorded by the Core Ultra 7 366H. Random string sorting shows another notable gap, with the Core 7 253PQE at 54222 versus 39814, a 36.2% lead. Extended instruction workloads also favor the desktop processor, with scores of 32390 and 26901 respectively, a 20.4% difference.

The Cinebench suite paints a consistent picture across all six tests. In Cinebench R23 multicore, the Core 7 253PQE scores 31390 while the Core Ultra 7 366H scores 28477, a 10.2% lead. The same 10.2% delta appears in Cinebench R23 singlecore (4431 versus 4020), Cinebench R20 multicore (13183 versus 11960), Cinebench R20 singlecore (1861 versus 1688), Cinebench R15 multicore (3163 versus 2870), and Cinebench R15 singlecore (446 versus 405). This uniform 10.2% margin across the entire Cinebench series suggests a consistent per-thread performance advantage rather than a workload-specific effect.

PassMark multithread performance shows the Core 7 253PQE at 41656, which is 24.6% above the 33429 of the Core Ultra 7 366H. The single-thread tests also favor the Core 7 253PQE, with a score of 4389 against 4043, an 8.6% difference. Floating point math is much closer, with the Core 7 253PQE at 105279 versus 103615, a modest 1.6% edge. Physics simulation shows a 3.1% advantage for the Core 7 253PQE, with scores of 2970 and 2880.

The Core Ultra 7 366H wins only two tests. The first is PassMark data encryption, where it scores 25845 against 25515, a 1.3% margin. This is the narrowest win in the dataset and suggests near-parity in encryption throughput. The second win is in PassMark find prime numbers, where the Core Ultra 7 366H scores 326 versus 206, a substantial 36.8% advantage. This is the only test where the mobile processor shows a significant performance lead, and it indicates a different strength profile in this specific algorithmic workload.

Where Each One Wins

The Intel Core 7 253PQE dominates across most workload categories. Its largest wins come in integer math (64.6% ahead), data compression (48.8% ahead), random string sorting (36.2% ahead), and multithread performance (24.6% ahead). These results indicate a processor that excels in general-purpose computing, data processing, and heavily threaded applications. The extended instruction advantage of 20.4% further reinforces this profile.

The Core 7 253PQE also holds a consistent 10.2% lead across all Cinebench versions, both single-core and multi-core. This uniformity suggests the advantage is not tied to a particular rendering or encoding workload but reflects a fundamental per-thread performance edge. The 8.6% single-thread lead in PassMark corroborates this interpretation.

The Intel Core Ultra 7 366H shows its strengths in two specific areas. The 36.8% advantage in PassMark find prime numbers is significant and indicates superior performance in prime-number generation algorithms. The 1.3% edge in data encryption, while small, shows the mobile processor can hold its own in cryptographic workloads.

For use-case planning, the data suggests the Core 7 253PQE is better suited for tasks involving large data transformations, compression, sorting, and heavy integer arithmetic. The Core Ultra 7 366H would be preferred for prime-number-intensive applications and shows near-parity in encryption. The physics simulation difference of only 3.1% means the two processors are effectively comparable for physics-based workloads.

The benchmark splits also reflect the different market positions. The Core 7 253PQE, with its 125 TDP and desktop socket, delivers higher sustained throughput in most tests. The Core Ultra 7 366H, with a 25 TDP, achieves competitive results in select workloads while consuming significantly less power per the recorded specifications.

Specification Differences

The Intel Core 7 253PQE uses 10 cores and 20 threads, while the Intel Core Ultra 7 366H uses 16 cores and 16 threads. This means the Core 7 253PQE has hyper-threading, effectively doubling its thread count, while the Core Ultra 7 366H has no thread-doubling, resulting in a 1:1 core-to-thread ratio.

Clock speeds differ substantially. The Core 7 253PQE has a base clock of 3.50 GHz and a boost clock of 5.70 GHz. The Core Ultra 7 366H has a base clock of 2.00 GHz and a boost clock of 4.80 GHz. The desktop processor holds a 1.50 GHz base clock advantage and a 0.90 GHz boost clock advantage.

Thermal design power differs by a factor of five. The Core 7 253PQE has a TDP of 125, while the Core Ultra 7 366H has a TDP of 25. This reflects the desktop versus mobile design philosophy.

Socket and platform requirements are entirely different. The Core 7 253PQE uses Intel Socket 1700, while the Core Ultra 7 366H uses Intel BGA 2540, indicating a soldered mobile installation rather than a replaceable desktop CPU.

Memory support diverges in both type and bandwidth. The Core 7 253PQE supports DDR4 and DDR5 with dual-channel memory and a bandwidth of 89.6 GB/s. The Core Ultra 7 366H supports DDR5 and LPDDR5X with dual-channel memory and a bandwidth of 115.2 GB/s. The mobile processor has a 25.6 GB/s bandwidth advantage.

ECC memory is supported only by the Core 7 253PQE. The Core Ultra 7 366H does not support ECC. PCIe configuration also differs, with the Core 7 253PQE offering Gen 5 with 16 lanes (CPU only) versus Gen 5 with 12 lanes (CPU only) for the Core Ultra 7 366H.

Integrated graphics are different models. The Core 7 253PQE uses UHD Graphics 770, while the Core Ultra 7 366H uses Intel Xe3 Graphics. The launch MSRP of the Core 7 253PQE is $409; the Core Ultra 7 366H has no recorded launch MSRP.

Architecture Differences

The two processors come from different architectural generations. The Intel Core 7 253PQE is based on Bartlett Lake, belonging to the Core 7 (Bartlett Lake) generation. The Intel Core Ultra 7 366H is based on Panther Lake, belonging to the Ultra 7 (Panther Lake-H) generation. The latter is explicitly labeled as Panther Lake architecture in the database.

The manufacturing process differs significantly. The Core 7 253PQE is fabricated on a 10 nm node, while the Core Ultra 7 366H uses a 3 nm node, both at Intel foundry. This process difference likely explains the substantial TDP gap, with the smaller 3 nm node enabling a 25 TDP design.

Cache organization shows distinct approaches. The Core 7 253PQE has 80 KB of L1 cache per core and 2 MB of L2 cache per core, with 33 MB of shared L3 cache. The Core Ultra 7 366H has 192 KB of L1 per core and 2.5 MB of L2 per core, with 18 MB of shared L3 cache. The mobile processor has larger per-core L1 and L2 caches, while the desktop processor has nearly double the shared L3 capacity.

The market segments are explicitly different. The Core 7 253PQE is classified as a desktop processor, while the Core Ultra 7 366H is classified as mobile. This is consistent with the socket type, TDP, and memory support differences.

Release dates differ by roughly two months. The Core Ultra 7 366H was released earlier, while the Core 7 253PQE followed. Both are marked as Active in production status, and neither has an unlocked multiplier.

The part numbers also differ: SA4QA for the Core 7 253PQE and SA4R9Q9EL for the Core Ultra 7 366H. The combination of architecture, node, and market segment creates two very different processor designs, despite both being Intel products with similar naming conventions.
