AMD Ryzen 7 7735H vs Intel Core Ultra 5 245T Comparison

Where Each One Wins

The Intel Core Ultra 5 245T and AMD Ryzen 7 7735H occupy very different positions in the performance spectrum, and the benchmark data makes that split remarkably clear. Of the 15 head-to-head tests recorded in the database, the Intel part takes 14 victories, with the AMD chip claiming exactly one. That is not a close contest by any conventional reading, but the single AMD win is instructive about where each processor is built to excel.

The Intel Core Ultra 5 245T dominates in every category that stresses raw compute throughput. In Cinebench R23 multi-core, it scores 26,208 against the Ryzen's 10,920, a 140% advantage. That is the kind of margin that separates desktop-class rendering hardware from a mobile part. The same pattern holds in Cinebench R15 multi-core, where Intel leads 2,641 to 1,825, a 44.7% gap. Single-core performance is also firmly in Intel's corner: Cinebench R23 single-core shows 3,699 versus 1,536, a 140.8% lead, and Cinebench R15 single-core shows 372 versus 246, a 51.2% edge. The Intel part's boost clock of 5.10 GHz against the AMD's 4.75 GHz helps explain the single-threaded supremacy, though the architectural differences run deeper.

PassMark's math and encryption workloads reinforce the Intel advantage. Floating point math goes to Intel at 108,499 versus 49,260, a 120.3% margin. Data encryption shows Intel at 23,656 against 18,990, a 24.6% lead. The prime number finding test is the most lopsided result in the entire comparison: Intel scores 324, AMD scores 59, a 449.2% difference. Physics simulation also heavily favors Intel at 2,278 versus 1,056, a 115.7% gap. Multi-threaded PassMark has Intel at 30,833 versus 23,765, a 29.7% win.

The AMD Ryzen 7 7735H's sole victory comes in PassMark data compression, where it scores 303,502 against Intel's 283,812, a 6.5% advantage. That is a notable result because data compression workloads often reward memory bandwidth and cache efficiency patterns that differ from raw ALU throughput. The Ryzen's 16 threads against Intel's 14 threads may also play a role here, as compression tasks can scale with thread count in ways that other workloads do not. The AMD part also keeps several other PassMark tests close: integer math is nearly a tie at 86,788 versus 88,676 (a 2.2% Intel win), and extended instructions land at 21,214 versus 22,071 (a 4% Intel win). Random string sorting favors Intel 34,931 to 31,676, a 10.3% margin.

The overall benchmark averages reflect this split. The Intel Core Ultra 5 245T posts an average benchmark score of 38,194, placing it in the 86th percentile of all CPUs in the database. The AMD Ryzen 7 7735H averages 37,161, sitting at the 85th percentile. Those are adjacent percentile ranks, but the head-to-head deltas show how much the Intel part pulls ahead in the most demanding tests.

The Verdict

The data points to a clear conclusion: the Intel Core Ultra 5 245T is the stronger processor for almost every compute-heavy task. It wins 14 of 15 head-to-head benchmarks, with margins that range from a modest 2.2% in integer math to a staggering 449.2% in prime number finding. Anyone prioritizing multi-core rendering, single-thread responsiveness, encryption throughput, or physics simulation should choose the Intel part without hesitation.

The AMD Ryzen 7 7735H is the pick only for a narrow use case. Its data compression score of 303,502 tops Intel's 283,812, so workloads that are specifically compression-bound, such as certain archiving or database compression pipelines, will see a slight edge on the AMD chip. Beyond that single test, the Ryzen's 8 cores and 16 threads at a 35W TDP make it the power-efficient mobile option, while the Intel part's 65W TDP and desktop Socket 1851 platform position it as a desktop-oriented processor. The launch MSRP for the Intel chip is $270; the AMD part has no recorded launch MSRP.

For a desktop build where performance is the priority, the Intel Core Ultra 5 245T is the clear winner. For a thin-and-light laptop where power draw and the mobile form factor matter, the Ryzen 7 7735H is the only one of the two that fits, since it is an AMD Socket FP7 mobile part. If the choice is strictly about benchmark results, the verdict is one-sided: Intel wins.

Head-to-Head Benchmarks

The largest Intel victory in the entire comparison is the PassMark find prime numbers test. Intel scores 324, AMD scores 59, giving Intel a 449.2% lead. This test is heavily dependent on integer instruction efficiency and clock speed, and the Intel part's Arrow Lake architecture with a 5.10 GHz boost clock simply runs away with it.

Cinebench R23 multi-core shows the second-largest gap. Intel's 26,208 against AMD's 10,920 is a 140% advantage. This is a rendering workload that scales with core count and IPC, and the Intel part's 14 cores on a 3nm TSMC process outpace the AMD chip's 8 cores on a 6nm process by a wide margin. The single-core version of the same test shows a 140.8% lead (3,699 versus 1,536), indicating that Intel's advantage is not merely about core count but also about per-core performance.

Floating point math in PassMark gives Intel a 120.3% win at 108,499 versus 49,260. Physics simulation follows at 115.7% (2,278 versus 1,056). These two tests together suggest that the Intel part is dramatically better at scientific and simulation workloads that rely on floating-point throughput.

The Cinebench R15 tests show more moderate but still decisive Intel wins. Multi-core goes 2,641 to 1,825, a 44.7% margin, while single-core goes 372 to 246, a 51.2% margin. PassMark multi-thread gives Intel a 29.7% win at 30,833 versus 23,765, and single-thread gives Intel a 32.8% win at 4,367 versus 3,288.

Data encryption favors Intel 23,656 to 18,990, a 24.6% margin. Random string sorting goes to Intel 34,931 to 31,676, a 10.3% win. Extended instructions are close at 22,071 versus 21,214, a 4% Intel edge. Integer math is the closest Intel win at 88,676 versus 86,788, just 2.2% apart.

The only AMD win is data compression at 303,502 versus 283,812, a 6.5% margin. That result stands out because it is the only test where the AMD part's 16 threads outperform Intel's 14 threads, and it suggests that compression workloads on the Ryzen 7 7735H have a measurable efficiency advantage.

Architecture Differences

The two processors come from fundamentally different design philosophies. The Intel Core Ultra 5 245T is a desktop part from the Core Ultra Series 2, built on the Arrow Lake architecture (codename Arrow Lake-S) and manufactured on a 3nm process at TSMC. It uses the Intel Socket 1851 platform and carries 17,800 million transistors on a 243 mm² die. The AMD Ryzen 7 7735H is a mobile processor from the 7000 series, built on the Zen 3+ architecture (codename Rembrandt-R) and manufactured on a 6nm process, also at TSMC. Its die size is 208 mm², and the database does not record a transistor count.

Core configuration differs sharply. Intel uses 14 cores and 14 threads, meaning no hyperthreading on this part. AMD uses 8 cores and 16 threads, relying on simultaneous multithreading to reach its thread count. The Intel part's L1 cache is 192 KB per core, its L2 cache is 3 MB per core, and its L3 cache is 24 MB shared. The AMD part has a smaller L1 at 64 KB per core and L2 at 512 KB per core, with 16 MB of shared L3 cache. The larger Intel cache hierarchy, especially the per-core L2, contributes to its strong single-threaded results.

Memory support is dual-channel DDR5 on both parts, but Intel's memory bandwidth is 102.4 GB/s versus AMD's 76.8 GB/s. Both support ECC memory. PCIe connectivity differs by generation: Intel offers Gen 5 with 20 lanes (CPU only), while AMD offers Gen 4 with 20 lanes (CPU only). The Intel part's newer PCIe standard provides more bandwidth for expansion devices.

Integrated graphics also diverge. Intel includes Arc Xe-LPG Graphics with 64 execution units, while AMD includes Radeon 680M. The database does not record benchmark scores for the iGPUs, so their relative performance cannot be quantified here.

Power and platform positioning are the biggest practical differences. The Intel part has a 65W TDP and targets the desktop segment with Socket 1851. The AMD part has a 35W TDP and targets the mobile segment with Socket FP7. The Intel part launched on January 6, 2025 with a launch MSRP of $270, while the AMD part launched on March 31, 2023 with no recorded MSRP. Both are listed as active in production. Neither processor has an unlocked multiplier.

The process node gap, 3nm versus 6nm, explains much of the efficiency and performance delta. TSMC's 3nm process gives Intel's Arrow Lake a transistor density and power efficiency advantage that shows up directly in the benchmark margins. The Intel part's 86th percentile ranking against all CPUs, versus AMD's 85th percentile, places them near each other in the overall distribution, but the head-to-head tests reveal that the Intel part is far ahead in the workloads that matter most for compute-intensive tasks. The AMD part's single data compression win and its 16-thread count are its main distinguishing features, but they do not offset the broad Intel dominance across the rest of the benchmark suite.
