Intel Core 7 253PTE vs Intel Core i7-13800H Comparison

The Intel Core i7-13800H and the Intel Core 7 253PTE are two very different interpretations of the same underlying 10nm Intel process, separated by roughly three years of design philosophy. While their aggregate benchmark scores are nearly identical — the i7-13800H posts an average of 34,988 against the Core 7's 34,962 — the individual workloads tell a story of a mobile chip that excels at bursty, latency-sensitive tasks versus a desktop part that dominates sustained compute. The data reveals a split decision: the 253PTE wins the Cinebench suite outright, while the 13800H claims victory in the majority of PassMark's specialized tests.

FAQ

Q: Which processor has the higher average benchmark score?

A: The Intel Core i7-13800H edges out the Intel Core 7 253PTE by a razor-thin margin, with an average benchmark score of 34,988 compared to 34,962. This represents a delta of just 0.1% in favor of the i7-13800H, placing both in the same performance class.

Q: How do the two chips compare in Cinebench R23 multi-core performance?

A: The Intel Core 7 253PTE is decisively faster, scoring 21,276 versus the i7-13800H's 18,358. This translates to a 13.7% advantage for the 253PTE in this heavily multithreaded rendering workload.

Q: Which processor shows a stronger result in the PassMark physics test?

A: The Intel Core i7-13800H wins by a substantial margin, scoring 1,924 against the Core 7 253PTE's 1,318. The i7-13800H holds a 46% lead in this particular benchmark, which typically reflects gaming and real-time simulation performance.

Q: What are the core and thread counts for each part?

A: The Intel Core i7-13800H features 14 cores and 20 threads, while the Intel Core 7 253PTE has 10 cores and 20 threads. The 253PTE achieves thread parity through hyper-threading on fewer physical cores.

Q: Is there a difference in memory bandwidth support?

A: Yes. The Intel Core 7 253PTE specifies a memory bandwidth of 89.6 GB/s, whereas the Intel Core i7-13800H does not have a listed memory bandwidth figure in the data. Both support DDR4 and DDR5 memory in a dual-channel configuration.

Q: Which CPU has the higher boost clock?

A: The Intel Core 7 253PTE boosts to 5.40 GHz, which is higher than the i7-13800H's 5.20 GHz boost. The 253PTE also has a lower base clock of 1.80 GHz versus 2.50 GHz on the i7-13800H.

Architecture Differences

The two processors stem from different architectural lineages despite sharing the same 10nm process node and Intel as the foundry. The Core i7-13800H is built on Raptor Lake, specifically the Raptor Lake-H mobile variant, while the Core 7 253PTE uses the Bartlett Lake codename. This is not a minor naming difference: the 13800H targets mobile platforms with an Intel BGA 1744 socket, while the 253PTE is a desktop part designed for Intel Socket 1700.

The core configurations diverge significantly. The i7-13800H packs 14 physical cores, whereas the 253PTE uses 10. Both expose 20 threads, meaning the 253PTE relies more heavily on simultaneous multithreading to reach the same thread count. The cache hierarchy shows a notable shift: the 253PTE offers a larger 33 MB shared L3 cache, while the i7-13800H is limited to 24 MB. Per-core L1 and L2 caches are identical at 80 KB and 2 MB respectively, suggesting the same core microarchitecture is at play.

The integrated graphics differ, with the mobile 13800H featuring Iris Xe Graphics with 96 execution units, while the desktop 253PTE includes the more modest UHD Graphics 730. The 253PTE adds ECC memory support, a feature absent from the i7-13800H. PCIe connectivity also differs: the 253PTE provides 16 CPU lanes of Gen 5 versus 8 Gen 5 lanes on the i7-13800H, reflecting the desktop part's need for more expansion bandwidth. The 253PTE has a larger die size unspecified in the data, but the i7-13800H measures 257 mm².

Head-to-Head Benchmarks

The Cinebench suite is a clean sweep for the Intel Core 7 253PTE. Across R15, R20, and R23, the 253PTE wins both multi-core and single-core tests by a consistent 13.6-13.7%. In R23 multi-core, the 253PTE scores 21,276 versus 18,358; in single-core it posts 3,003 against 2,591. This uniformity across all Cinebench versions indicates a fundamental clock-speed and IPC advantage rather than workload-specific behavior. The 253PTE's higher 5.40 GHz boost clock is likely the primary driver.

The PassMark results paint a more complex picture. The i7-13800H wins seven of the fifteen head-to-head comparisons (excluding the duplicate single-thread entry). Its largest victory is in physics, where it scores 1,924 against 1,318, a 46% margin. The i7-13800H also wins find prime numbers by 40.2% (115 vs 82), random string sorting by 17.6% (33,188 vs 28,227), and data encryption by 14.4% (17,726 vs 15,500). Data compression goes to the i7-13800H by 8.5% (299,179 vs 275,828), and it also takes the multithread test by 6% (26,545 vs 25,031) and extended instructions by 5.3% (18,011 vs 17,099).

The 253PTE counters with a dominant integer math performance, scoring 119,552 against the i7-13800H's 92,589 — a 22.6% advantage. It also wins single-thread by 6.6% (3,794 vs 3,543) and floating point math by a marginal 0.9% (67,209 vs 66,579). The overall win count favors the 253PTE at 10 wins to 7, but the average benchmark score remains essentially tied.

The Verdict

The data suggests two different usage profiles. The Intel Core 7 253PTE is the clear choice for sustained multithreaded rendering workloads, as evidenced by its 13.7% lead across the entire Cinebench R15/R20/R23 stack. Its integer math advantage of 22.6% also points to strength in general-purpose compute tasks like compilation or data processing. The 253PTE's higher boost clock and larger L3 cache appear to translate directly into better raw throughput.

The Intel Core i7-13800H, despite losing the Cinebench suite, holds advantages in several latency-sensitive and specialized workloads. Its 46% physics lead and 40.2% prime number advantage suggest superior responsiveness in interactive applications, possibly due to the larger physical core count of 14 versus 10. The 17.6% win in random string sorting and 14.4% in data encryption indicate the i7-13800H is better suited for database workloads and security-related tasks.

For a buyer, the decision hinges on the workload mix. Pure rendering and CPU-bound desktop computing favor the 253PTE. Mixed workloads with encryption, compression, and physics simulation favor the i7-13800H. The 253PTE also offers ECC memory support and 16 PCIe lanes, making it more appropriate for a workstation or server environment. The i7-13800H's mobile socket and Iris Xe graphics make it a fit for high-performance laptops. Both chips sit in the 84th percentile of all CPUs, so neither is a weak choice.
