AMD Ryzen 5 7535HS vs Intel Core i5-1345U Comparison

The Intel Core i5-1345U and AMD Ryzen 5 7535HS are both mobile processors aimed at thin-and-light laptops, yet the benchmark data reveals two distinctly different personalities. The Intel chip, built on Raptor Lake, wins on pure single-core speed and a couple of specialized math workloads, while the AMD part, based on Zen 3+, dominates multi-core throughput and data processing tasks by wide margins. With 15 head-to-head benchmarks, AMD takes 10 wins to Intel’s 5, but the margins on Intel’s victories are often larger in percentage terms, making the choice highly workload-dependent.

Where Each One Wins

The AMD Ryzen 5 7535HS is the clear choice for parallel, multi-threaded workloads. Its wins span Cinebench R15 and R23 multi-core tests, PassMark’s multithread, data compression, encryption, extended instructions, integer math, prime numbers, physics, and random string sorting. In these tests, the AMD part consistently outperforms the Intel chip by margins ranging from a modest 3.1% in physics to a commanding 40.4% in extended instructions. The data suggests that content creation, video encoding, database work, or any task that can leverage all 12 threads will see a significant benefit from the Ryzen 5 7535HS.

Conversely, the Intel Core i5-1345U wins in single-core performance and two specific math areas. It takes Cinebench R15 single-core by 3.4% and R23 single-core by a substantial 19.3%. It also edges out the AMD chip in PassMark’s floating-point math by 1.1% and in the single-thread PassMark test by 9.3%. This makes the Intel part more appealing for lightweight, latency-sensitive applications like web browsing, office productivity, and legacy software that relies heavily on one or two cores.

The division is stark: AMD for throughput, Intel for responsiveness. The benchmark results indicate a classic trade-off between raw compute density and clock-speed-driven single-core agility.

Architecture Differences

The two processors take fundamentally different design approaches. The Intel Core i5-1345U is built on Intel’s 10 nm process and uses the Raptor Lake architecture, specifically the Raptor Lake-U codename. It features 10 cores and 12 threads, with a base clock of 1600 MHz and a boost clock of 4.70 GHz. Its cache hierarchy is generous per-core: 80 KB of L1 and 1.25 MB of L2 per core, with a shared 12 MB L3. The chip supports both DDR4 and DDR5 memory in a dual-channel configuration, and its PCIe implementation is Gen 4 with 8 lanes from the CPU.

AMD’s Ryzen 5 7535HS is a 6-core, 12-thread part based on the Zen 3+ architecture, codenamed Rembrandt-R. It is manufactured on TSMC’s 6 nm process, a smaller node than Intel’s offering. The base clock is significantly higher at 3.30 GHz, but the boost clock is slightly lower at 4.55 GHz. Its cache is smaller per core (64 KB L1 and 512 KB L2) but has a larger shared L3 pool at 16 MB. The AMD chip supports only DDR5 memory, dual-channel, with a rated bandwidth of 76.8 GB/s. Its PCIe implementation is more expansive, with Gen 4 and 20 lanes from the CPU.

The TDP difference is notable: Intel’s part is rated at 15W, while AMD’s is rated at 35W. This explains the performance gulf in sustained multi-core workloads, as the AMD chip has a higher power envelope to feed its higher base clock. The integrated graphics also differ, with Intel using Iris Xe Graphics 80EU and AMD using Radeon 660M. Both are mobile parts on different sockets (Intel BGA 1744 for Intel, AMD Socket FP7 for AMD), and both were released on the same day in early 2023.

Head-to-Head Benchmarks

The largest single win for AMD comes in PassMark’s extended instructions test, where the Ryzen 5 7535HS scores 15411 against Intel’s 9178, a 40.4% delta. This is a massive gap that points to AMD’s superior SIMD and vector processing capabilities. Data compression also heavily favors AMD, with a score of 221668 versus 164005, a 26% advantage. Encryption follows suit at 13656 versus 10288, a 24.7% lead for AMD. These three tests alone make a compelling case for the AMD chip in data-centric workloads.

In multi-core rendering, AMD’s lead is consistent but smaller. Cinebench R23 multi-core shows AMD at 8613 versus Intel’s 7724, a 10.3% difference. The R15 multi-core test shows a similar 10% gap, with AMD at 1457 and Intel at 1311. PassMark’s multithread test shows AMD ahead at 17914 versus 14511, a 19% margin. Integer math also goes to AMD, 62372 versus 52847, a 15.3% lead.

Intel’s wins, while fewer, are decisive in single-core metrics. The standout is Cinebench R23 single-core, where Intel scores 1724 against AMD’s 1445, a 19.3% advantage. PassMark single-thread shows Intel at 3415 versus 3123, a 9.3% lead. Cinebench R15 single-core is closer, with Intel at 240 versus 232, only a 3.4% edge. In floating-point math, the two are nearly tied, with Intel at 35939 and AMD at 35540, a marginal 1.1% win for Intel.

The Verdict

The data is unambiguous for multi-threaded tasks: the AMD Ryzen 5 7535HS is the superior processor. It wins 10 out of 15 head-to-head benchmarks, and its victories in compression, encryption, and extended instructions are not just wins but landslides. For anyone running video renders, compiling code, processing large datasets, or doing any form of parallel computation, the AMD chip offers a 10-40% performance uplift depending on the workload. Its higher 35W TDP and larger 16 MB L3 cache appear to be the driving factors behind this dominance.

The Intel Core i5-1345U, however, retains a clear edge in single-core performance, particularly in Cinebench R23 where it leads by nearly 20%. This translates to snappier application launching and better performance in lightly threaded software. Its 15W TDP also suggests it will be more efficient in short bursts, though the benchmark data does not quantify power draw. For users who prioritize fast single-core response over raw throughput, the Intel part is the better choice, but for everything else, AMD wins.

Both chips sit at the 73rd percentile of all CPUs, indicating they are closely matched overall. Intel’s average benchmark score is 19411, while AMD’s is 19047, a negligible difference of less than 2%. The choice ultimately comes down to whether you value AMD’s multi-core muscle or Intel’s single-core agility.
