AMD Ryzen 7 7735HS vs Intel Core i5-13400 Comparison

The Verdict

The benchmark data splits this matchup into two very different product philosophies. The Intel Core i5-13400 is a desktop processor built for all-core workloads and consistent single-thread performance, while the AMD Ryzen 7 7735HS is a mobile chip optimized for efficiency and specific instruction-heavy tasks. If you are building a desktop system and care about raw multi-threaded throughput, the i5-13400 is the clear pick: it wins 19 of the 23 head-to-head comparisons, including massive margins in Cinebench R23 multi-core (21.7% ahead) and Geekbench multi-core (51.5% ahead). If you are selecting a laptop and your workload involves encryption, integer math, or extended instruction sets, the Ryzen 7 7735HS takes those specific categories with deltas of 12.9%, 8.9%, and 4.4% respectively. The Ryzen also carries a higher average benchmark score overall (25147 versus 24280), but that figure is skewed by its efficiency-oriented design and does not translate into wins in most of the individual tests. For a desktop builder, the i5-13400 is the straightforward recommendation. For a mobile buyer who prioritizes battery-conscious performance and specific math workloads, the 7735HS is the only choice between these two.

Q: Do both chips support the same memory types?

A: No. The Intel Core i5-13400 supports DDR4 and DDR5, while the AMD Ryzen 7 7735HS supports DDR5 only. Both use a dual-channel memory bus, and AMD lists a memory bandwidth of 76.8 GB/s.

Architecture Differences

The Intel Core i5-13400 uses the Raptor Lake architecture, specifically the Raptor Lake-S desktop variant. It is built on Intel's 10 nm process at Intel's own foundry. The die size is 215 mm². The chip features 10 cores arranged with a hybrid design, and each core has 80 KB of L1 cache and 1.25 MB of L2 cache. The shared L3 cache is 20 MB. It supports DDR4 and DDR5 memory over a dual-channel bus, and it lacks ECC memory support. The integrated graphics are UHD Graphics 730. The PCIe implementation is Gen 5 with 16 CPU lanes. It uses the Intel Socket 1700 and is a desktop market segment part. It was released on 2023-01-03 and carries a launch MSRP of $221.

The AMD Ryzen 7 7735HS uses the Zen 3+ architecture with the Rembrandt-R codename. It is built on TSMC's 6 nm process, a newer node than Intel's 10 nm. The die size is 210 mm², nearly identical to Intel's. Each core has 64 KB of L1 cache and 512 KB of L2 cache, and the shared L3 cache is 16 MB. It supports only DDR5 memory with a dual-channel bus and lists a memory bandwidth of 76.8 GB/s. Unlike Intel, it supports ECC memory. The integrated graphics are Radeon 680M. The PCIe implementation is Gen 4 with 20 CPU lanes. The socket is AMD Socket FP7, and the market segment is mobile. It was released on 2023-03-31, later than the Intel part.

The process node difference is significant: TSMC's 6 nm versus Intel's 10 nm likely explains why AMD achieves higher clocks (4.75 GHz boost versus 4.60 GHz) at a much lower TDP (35 W versus 65 W). The cache structures also differ meaningfully, with Intel allocating more L2 per core and a larger shared L3 pool. AMD counters with ECC support and a more powerful integrated GPU in the Radeon 680M.

Base clocks are 2.50 GHz for Intel and 3.20 GHz for AMD. Boost clocks are 4.60 GHz for Intel and 4.75 GHz for AMD. TDP is 65 W for Intel and 35 W for AMD. Sockets differ: Intel Socket 1700 versus AMD Socket FP7. Process nodes differ: 10 nm Intel versus 6 nm TSMC. Die sizes are close: 215 mm² versus 210 mm². L1 cache is 80 KB per core for Intel versus 64 KB per core for AMD. L2 cache is 1.25 MB per core for Intel versus 512 KB per core for AMD. L3 cache is 20 MB shared for Intel versus 16 MB shared for AMD. Memory support is DDR4 and DDR5 for Intel versus DDR5 only for AMD. ECC memory is not supported on Intel but is supported on AMD. PCIe is Gen 5 with 16 lanes for Intel versus Gen 4 with 20 lanes for AMD. Integrated graphics are UHD Graphics 730 for Intel versus Radeon 680M for AMD. The memory bandwidth figure of 76.8 GB/s appears only for AMD. The market segment is desktop for Intel and mobile for AMD. Release dates are 2023-01-03 for Intel and 2023-03-31 for AMD. The launch MSRP of $221 applies only to Intel; no MSRP is recorded for the AMD part.

Head-to-Head Benchmarks

The largest single delta in the entire comparison is Geekbench multi-core, where the Intel Core i5-13400 scores 12289 versus 8114 for the Ryzen 7 7735HS, a 51.5% advantage. That is a crushing margin and indicates the Intel chip handles heavily threaded general-purpose workloads far better. Geekbench single-core also favors Intel: 2112 versus 1699, a 24.3% lead. Cinebench R23 multi-core shows a 21.7% Intel lead (15953 versus 13106), and Cinebench R23 single-core shows a 15.5% lead (1786 versus 1546). PassMark floating point math goes to Intel by 22.8% (58786 versus 47865). PassMark find prime numbers goes to Intel by 25.4% (74 versus 59). PassMark physics goes to Intel by 15.9% (1244 versus 1073). PassMark single-thread goes to Intel by 7.3% (3538 versus 3296). The 3DMark suite mostly favors Intel: 16 threads by 6.5%, 2 threads by 6.2%, 4 threads by 2.3%, max threads by 6.4%, and single thread by 5.2%. The one 3DMark exception is 8 threads, where AMD wins 5697 versus 5592, a 1.8% margin. Cinebench R15 multi-core goes to Intel by 9.5% (2358 versus 2153.4), and R15 single-core goes to Intel by 3.6% (257 versus 248). PassMark multithread goes to Intel by 2.4% (23719 versus 23166). PassMark data compression goes to Intel by 2.8% (301481 versus 293278). PassMark random string sorting goes to Intel by 1.5% (30851 versus 30388).

The AMD Ryzen 7 7735HS wins four tests. PassMark data encryption shows AMD ahead by 12.9% (18237 versus 15880). PassMark integer math shows AMD ahead by 8.9% (85309 versus 77721). PassMark extended instructions shows AMD ahead by 4.4% (20050 versus 19161). The 3DMark 8-thread test completes the AMD set with a 1.8% margin. These are not trivial wins; the encryption and integer math categories are substantial margins that suggest architectural strengths in specific instruction paths.

Where Each One Wins

The Intel Core i5-13400 dominates rendering and general-purpose compute. In Cinebench R23 multi-core, it is 21.7% ahead, and in Geekbench multi-core, it is 51.5% ahead. Anyone running video encoding, 3D rendering, compilation, or other heavily threaded desktop tasks should choose the i5-13400. It also wins all single-thread tests in the database, from 3DMark single thread (5.2% ahead) to Geekbench single core (24.3% ahead) to PassMark single thread (7.3% ahead). The floating-point math advantage of 22.8% reinforces its position for scientific and simulation workloads. The 2.8% lead in data compression and 1.5% lead in random string sorting make it slightly better for file archiving and text processing tasks. With 19 wins out of 23 head-to-head tests, the Intel chip is the default choice for almost any desktop workflow.

The AMD Ryzen 7 7735HS wins in encryption, integer math, and extended instruction workloads. The 12.9% lead in data encryption suggests it is the better pick for secure file operations, VPN traffic handling, or any workload that relies on AES-style instructions. The 8.9% lead in integer math points to strength in certain database or financial workloads that are integer-bound. The 4.4% lead in extended instructions indicates the Zen 3+ architecture handles AVX-style or specialized instruction sets more efficiently. The 3DMark 8-thread win, while narrow at 1.8%, suggests that in a mid-thread count scenario, the AMD chip can hold its own. For a mobile user, the 35 W TDP is a decisive practical advantage: the Ryzen delivers competitive performance in a laptop form factor while drawing far less power than the desktop-bound Intel part. The Radeon 680M integrated graphics also give it a stronger iGPU option for light gaming or media work. The data shows a clear split: Intel for desktop throughput, AMD for mobile efficiency and specific instruction-heavy tasks.
