Intel Core 7 253PTE vs Intel Core Ultra 5 336H Comparison

The Intel Core Ultra 5 336H and the Intel Core 7 253PTE represent two distinct philosophies in processor design, yet they land in nearly the same performance tier. The data shows a clear overall winner in the Ultra 5 336H, which takes 16 of 17 head-to-head benchmark comparisons. However, the single loss is a massive one, revealing a fundamental difference in workload suitability that prevents this from being a complete sweep.

The Verdict

Based strictly on the benchmark data, the Intel Core Ultra 5 336H is the superior processor for the vast majority of tasks. Its average benchmark score of 34485 places it in the 84th percentile of all CPUs, and it edges out the Core 7 253PTE despite the latter having a slightly higher average score of 34962, which also sits in the 84th percentile. The Ultra 5 336H wins the multicore Cinebench tests by a consistent margin of 12.8%, and dominates in specialized workloads like data encryption and physics simulations, where it leads by 37.4% and 103.5% respectively.

However, the verdict is not universal. The Core 7 253PTE is the only choice for workloads heavily dependent on integer math. Its Passmark integer math score of 119552 is nearly double the Ultra 5 336H's 62070, a 48.1% advantage. Users running such calculations should choose the Core 7 253PTE without hesitation. For anyone else, the Ultra 5 336H offers better all-around performance, a more modern platform, and a significantly lower thermal design power of 25 watts compared to the Core 7's 45 watts, making it the more efficient and versatile pick.

Where Each One Wins

The benchmark results split the two processors into clear functional camps. The Intel Core Ultra 5 336H is the generalist champion, winning in all three Cinebench iterations (R15, R20, R23) for both single and multi-threaded tests. It also excels in memory-intensive and encryption tasks, leading in data encryption by 37.4% and floating-point math by 22.6%. Its wins in physics (103.5% lead) and prime number finding (264.6% lead) suggest a significant advantage in scientific and simulation-based applications.

The Intel Core 7 253PTE, conversely, is a specialist. Its only win comes in the Passmark integer math benchmark, where its score of 119552 dwarfs the Ultra 5's 62070. This indicates a design tuned for specific arithmetic operations, making it the go-to choice for software that relies heavily on integer processing, such as certain database workloads or legacy applications. It is also importantly despite having fewer cores (10 vs 16), it has more threads (20 vs 16), hinting at a different scheduling architecture that benefits specific parallel tasks, though this does not translate to wins in the tested multi-threaded applications.

Architecture Differences

The two processors are built on fundamentally different foundations. The Intel Core Ultra 5 336H is a mobile part based on the Panther Lake architecture, manufactured on a 3 nm process node. It features 16 cores and 16 threads, with a base clock of 1.90 GHz and a boost clock of 4.60 GHz. Its cache hierarchy includes 192 KB of L1 and 2.5 MB of L2 per core, with a shared 18 MB L3 cache. This chip is designed for the Intel BGA 2540 socket and supports DDR5 and LPDDR5X memory with a dual-channel bus, offering a memory bandwidth of 115.2 GB/s. It integrates Intel Xe3 Graphics and supports PCIe Gen 5 with 12 CPU lanes.

The Intel Core 7 253PTE is a desktop processor from the Bartlett Lake codename family, built on a more mature 10 nm process. It has 10 cores but 20 threads, indicating Hyper-Threading support. Its clocks are more aggressive, with a base of 1.80 GHz and a boost of 5.40 GHz. The cache layout differs significantly: it has 80 KB of L1 and 2 MB of L2 per core, but a much larger shared L3 cache of 33 MB. It uses the Intel Socket 1700 and supports both DDR4 and DDR5 memory, though its dual-channel bus yields a lower memory bandwidth of 89.6 GB/s. It features UHD Graphics 730 and supports PCIe Gen 5 with 16 CPU lanes, and includes ECC memory support. The Core 7 also has a higher TDP of 45 watts.

FAQ

Q: Which processor is better for multi-threaded rendering?

A: The Intel Core Ultra 5 336H is clearly superior. In Cinebench R23 multi-core, it scores 23991 compared to the Core 7 253PTE's 21276, a 12.8% advantage. This margin is consistent across Cinebench R15 and R20 multi-core tests as well.

Q: The Core 7 has a higher boost clock (5.40 GHz vs 4.60 GHz), so why does it lose single-threaded tests?

A: Despite the higher boost clock, the Core 7 253PTE loses all single-threaded Cinebench tests by 12.8-12.9%. The Ultra 5 336H's architecture achieves better instructions-per-clock, resulting in a Cinebench R23 single-core score of 3387 versus the Core 7's 3003, and a Passmark single-thread score of 4013 versus 3794.

Q: Are there any workloads where the Core 7 253PTE is the better choice?

A: Yes, specifically for integer math operations. The Core 7 253PTE scores 119552 in Passmark's integer math test, which is 48.1% higher than the Ultra 5 336H's 62070. This is the only benchmark in the comparison that the Core 7 wins.

Q: How do their memory capabilities differ?

A: The Ultra 5 336H supports DDR5 and LPDDR5X with a memory bandwidth of 115.2 GB/s, while the Core 7 253PTE supports both DDR4 and DDR5 but has a lower bandwidth of 89.6 GB/s. The Ultra 5 also does not support ECC memory, whereas the Core 7 does.

Q: Which processor is more energy-efficient?

A: The Ultra 5 336H has a thermal design power of 25 watts, compared to the Core 7 253PTE's 45 watts. This indicates the Ultra 5 is designed for lower power consumption and is likely better suited for thinner, more portable devices.

Q: How does the Core 7 253PTE compare to its own rivals?

A: The data shows it performs in line with the Intel Core i7-13800H and Intel Core i9-12900HX, with a deltaPct of -0.1% against both. It is also 0.2% ahead of the Intel Xeon 6349P and AMD Ryzen 5 150.

Head-to-Head Benchmarks

The most striking result is in the Passmark find prime numbers test, where the Ultra 5 336H scores 299 against the Core 7's 82, a massive 264.6% delta. This suggests a dramatic advantage in certain computational loops. The physics test is similarly lopsided, with the Ultra 5 scoring 2682 versus 1318, a 103.5% lead. In data encryption, the Ultra 5's 21291 score is 37.4% higher than the Core 7's 15500, and in extended instructions, it leads by 43.5% (24542 vs 17099).

The Cinebench results are consistently in favor of the Ultra 5 336H. Across R15, R20, and R23, both single and multi-core tests show a 12.8% to 12.9% advantage for the Ultra 5. For instance, in Cinebench R23 multi-core, the Ultra 5 scores 23991, while the Core 7 scores 21276. The Passmark multithread test confirms this trend with a 14% lead for the Ultra 5 (28545 vs 25031).

The sole victory for the Core 7 253PTE is in Passmark integer math, where it scores 119552. This is a 48.1% improvement over the Ultra 5's 62070 and is the largest single delta in the entire comparison outside of the prime number test. This single data point highlights a fundamental architectural strength in integer arithmetic for the Core 7, but it is an outlier in an otherwise dominant performance by the Ultra 5 336H.

Specification Differences

The most significant difference lies in the process node and platform. The Ultra 5 336H uses a 3 nm process and the Panther Lake architecture, while the Core 7 253PTE uses a 10 nm process and the Bartlett Lake codename. This translates to the Ultra 5 having more cores (16 vs 10) but fewer threads (16 vs 20). The Core 7 has a higher boost clock (5.40 GHz vs 4.60 GHz) and a larger L3 cache (33 MB vs 18 MB). However, the Ultra 5 counters with a lower TDP (25 W vs 45 W) and higher memory bandwidth (115.2 GB/s vs 89.6 GB/s). The platforms are incompatible, with the Ultra 5 using Intel BGA 2540 and the Core 7 using Intel Socket 1700. The Core 7 supports ECC memory and a wider PCIe Gen 5 implementation at 16 lanes, while the Ultra 5 supports 12 lanes. The integrated graphics also differ, with the Ultra 5 featuring Intel Xe3 Graphics and the Core 7 featuring UHD Graphics 730. The Core 7 253PTE has a launch MSRP of $384.
