AMD Ryzen 9 6900HS vs Intel Core i7-13620H Comparison

The AMD Ryzen 9 6900HS and Intel Core i7-13620H sit in the same broad performance band of the database: both record a percentile ranking of 77 against all CPUs, and their aggregate benchmark averages are nearly tied at 25284 for the AMD chip and 24911 for the Intel part. Yet the recorded data shows a clear division of labor underneath that parity. The 13620H wins 15 of the 21 head-to-head tests, while the 6900HS takes 6, and the wins cluster in different workload types. What follows is a step-by-step walkthrough of where each processor earns its results.

Head-to-Head Benchmarks

The single-threaded picture is unambiguous. In 3DMark CPU single-thread the Intel Core i7-13620H posts 1008 against 915 for the Ryzen 9 6900HS, a lead of 9.2 percent. Cinebench R15 single-core goes to Intel as well, 263 to 245, a 6.8 percent margin. Cinebench R23 single-core is the widest rendering gap in Intel's favor: 1833 versus 1554, meaning the 13620H is 15.2 percent faster on a per-core basis. PassMark single-thread confirms the pattern at 3589 to 3237, a 9.8 percent advantage for the Raptor Lake part. Any workload that leans on one fast thread, from game logic to snappy application response, favors the Intel CPU in these measurements.

Low-thread-count tests tilt the same way but with shrinking margins as threads are added. In the 3DMark two-thread test the 13620H leads 1963 to 1761, a 10.3 percent gap. At four threads the margin narrows to 5.4 percent, 3621 versus 3427. At eight threads the lead flips: the 6900HS scores 5830 against 5443, a 7.1 percent win for AMD. That inversion is the structural signature of this matchup. The Ryzen chip has 8 full cores and 16 threads, so at eight concurrent threads all of its cores are engaged symmetrically, while the 13620H mixes core types across its 10 cores and 16 threads.

Full-load multithreaded tests mostly return to Intel. In 3DMark max-threads the 13620H scores 7178 to 6955, ahead by 3.1 percent, and in the 16-thread variant it leads 7056 to 6963 by 1.3 percent. Cinebench R23 multi-core shows the largest sustained-load gap in Intel's favor: 15176 against 13445, an 11.4 percent advantage. Cinebench R15 multi-core goes to Intel at 2281 to 2161, 5.3 percent, and PassMark multithread lands at 24192 versus 23152, a 4.3 percent Intel win. Two extra cores and a higher thermal envelope give the 13620H the edge when every thread is saturated.

The PassMark subsystem tests are where the 6900HS collects most of its wins, and some are substantial. Data encryption is its best result anywhere: 18303 against 15568, a 17.6 percent win. Extended instructions (SSE, AVX workloads) go to AMD at 20015 versus 17513, up 14.3 percent. Data compression favors AMD 292842 to 281335, 4.1 percent, integer math 86449 to 80948, 6.8 percent, and string sorting 30528 to 29395, 3.9 percent. Against that, Intel dominates two integer-heavy PassMark tests with enormous margins: find prime numbers at 99 versus 58, a 41.4 percent gap, and physics at 1671 to 1041, 37.7 percent ahead. Floating point math also goes to Intel, 59762 to 48239, 19.3 percent.

Where Each One Wins

The Intel Core i7-13620H is the clear choice for rendering and physics-heavy work. Cinebench R15 and R23, in both single- and multi-core modes, all land in its column, along with PassMark physics and floating point. A user running 3D rendering, simulation, or game physics workloads is choosing the CPU that wins every relevant recorded test, often by double digits: 11.4 percent in R23 multi-core, 15.2 percent in R23 single-core, 37.7 percent in physics.

The AMD Ryzen 9 6900HS wins where memory-bound integer and cryptographic throughput matter. Its encryption, compression, extended-instruction, and integer-math results are all superior, with encryption up 17.6 percent. It also wins the eight-thread scaling point, which matters for workloads sized to its symmetric 8-core, 16-thread layout: a 7.1 percent lead over the 13620H at that exact concurrency level. Developers compiling mid-sized projects, users handling archive or encryption workloads, and software that saturates roughly eight threads are better served by the recorded Ryzen numbers.

General responsiveness and lightly threaded performance belong to Intel across the board: every single- and low-thread-count test in the dataset favors the 13620H.

The Verdict

The data supports a split decision despite the near-identical aggregate scores. If the workload is rendering, physics simulation, floating-point computation, or anything that rewards peak single-thread speed, the Intel Core i7-13620H is the stronger pick: 15 of 21 head-to-head wins, including every Cinebench result and every single-threaded result. If the workload emphasizes encryption, compression, integer math, or exactly eight well-fed threads, the AMD Ryzen 9 6900HS delivers better numbers and does it from a lower 35-watt TDP rather than the Intel chip's 45 watts, a difference worth noting for thermally constrained designs. Both CPUs rank in the 77th percentile of the database, so neither is a downgrade in overall class: the decision comes down to workload shape.

Architecture Differences

The Ryzen 9 6900HS uses AMD's Zen 3+ architecture, codenamed Rembrandt, manufactured on TSMC's 6 nm process. The Core i7-13620H uses Intel's Raptor Lake architecture (Raptor Lake-H) on Intel's own 10 nm process. The Intel part launched on January 3, 2023 with a launch MSRP of $502; the database records no launch date or MSRP for the AMD part. Both are active mobile-segment products with locked multipliers.

The core topology differs in a way that directly explains the benchmark inversion at eight threads. AMD fields 8 identical cores with SMT for 16 threads; Intel fields 10 cores and 16 threads with a hybrid design. Cache allocation diverges sharply: AMD gives each core 64 KB of L1 and 512 KB of L2 with 16 MB of shared L3; Intel assigns 80 KB of L1 and 2 MB of L2 per core with a larger 24 MB shared L3. That L3 capacity edge is one plausible contributor to Intel's sustained multi-core rendering leads. AMD's die is recorded at 208 mm²; no die size is recorded for the Intel chip.

Platform features split as well. AMD supports DDR5 only, with a recorded dual-channel bandwidth of 76.8 GB/s, while Intel supports both DDR4 and DDR5 in dual-channel (no bandwidth figure is recorded). PCIe differs in generation and lane count: AMD offers 20 CPU lanes of Gen 4, Intel offers 8 CPU lanes of Gen 5. The integrated graphics contrast is stark: AMD pairs the 6900HS with the Radeon 680M, while the 13620H carries Intel UHD Graphics 770. Neither supports ECC memory.
