AMD Ryzen 7 7735U vs Intel Core i9-10900K Comparison

Head-to-Head Benchmarks

The benchmark data presents a clear split between these two processors, with the Intel Core i9-10900K dominating most multi-threaded and single-threaded workloads, while the AMD Ryzen 7 7735U secures a few targeted wins. Out of 17 recorded comparisons, Intel takes 14 victories and AMD takes 3.

The largest margin in the entire dataset belongs to AMD in passmark_data_encryption. The Ryzen 7 7735U scores 15,825 against the Core i9-10900K's 7,796, a 103% advantage. This is not a marginal difference; the AMD processor more than doubles the Intel processor's encryption throughput. This suggests architectural efficiency in cryptographic workloads that outweighs the Intel chip's higher core count and clock speeds.

Intel's biggest win comes in cinebench_r23_multicore, where the Core i9-10900K scores 18,895 versus the Ryzen's 10,085, a 46.6% deficit for AMD. The 10-core, 20-thread Intel part leverages its additional cores effectively in this heavily parallel rendering workload. The gap narrows in cinebench_r15_multicore, where Intel leads 1,904 to 1,698, a 10.8% margin. The older Cinebench version shows a smaller spread, indicating that the workload scaling favors Intel more as thread count demands increase.

Single-core performance also favors Intel throughout most tests. In cinebench_r23_singlecore, the Core i9-10900K scores 2,667 against 1,490, a 44.1% lead. The cinebench_r15_singlecore result shows 268 versus 234, a 12.7% margin. Geekbench_singlecore records 1,711 versus 1,442, a 15.7% gap. These results consistently point to higher per-thread performance from the Intel architecture at its 5.30 GHz boost clock.

PassMark results reinforce the pattern. Intel wins passmark_data_compression with 375,336 against 250,457, a 33.3% margin. Passmark_extended_instructions shows Intel ahead at 24,620 versus 16,349, a 33.6% gap. Passmark_random_string_sorting is a 43.2% win for Intel, 46,389 versus 26,365. Passmark_floating_point_math leans Intel at 53,123 versus 42,966, a 19.1% margin. Passmark_integer_math is closer, with Intel at 85,404 versus 79,580, only 6.8% ahead. Passmark_multithread shows Intel at 22,452 versus 20,723, a 7.7% margin. Passmark_find_prime_numbers is a narrow Intel win, 63 versus 57, a 9.5% gap. Passmark_physics is the tightest Intel victory: 1,029 versus 996, only 3.2% apart.

AMD's third win is passmark_single_thread, where the Ryzen 7 7735U scores 3,236 versus 3,113, a 4% edge. This is notable because every other single-thread test in the dataset favors Intel. The PassMark single-thread test apparently rewards something about the Zen 3+ architecture that the Cinebench and Geekbench single-thread tests do not capture, possibly related to instruction mix or memory latency characteristics.

The Verdict

The data indicates that the Intel Core i9-10900K is the stronger overall processor for compute-heavy workloads. Its 46.6% lead in cinebench_r23_multicore, 44.1% lead in cinebench_r23_singlecore, and 31.8% lead in geekbench_multicore establish it as the clear choice for rendering, compilation, and general productivity tasks. The average benchmark score supports this: Intel sits at 27,872 with a 79th percentile ranking, while AMD sits at 28,350 with an 80th percentile ranking. The percentile rankings are nearly identical, but the Intel chip achieves its position with a 125 W TDP desktop design, while the AMD chip does so within a 28 W mobile envelope.

The Ryzen 7 7735U is the pick for encryption-heavy workloads and for scenarios where the PassMark single-thread metric matters more than the Cinebench or Geekbench variants. The 103% encryption advantage is a decisive reason to choose AMD for tasks like disk encryption, VPN throughput, or secure data handling. Its 4% passmark_single_thread win also shows that the Zen 3+ core is competitive in at least one single-thread measurement.

For buyers who prioritize raw multi-core rendering or encoding performance, the Intel Core i9-10900K is the clear winner from this data. For those who prioritize cryptographic performance and power efficiency within a mobile platform, the AMD Ryzen 7 7735U holds the advantage. The Intel part is end-of-life production status, while the AMD part remains active, which may matter for availability considerations.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 7 7735U uses the Zen 3+ architecture, codenamed Rembrandt-R, built on a 6 nm process at TSMC. The Intel Core i9-10900K uses the Comet Lake architecture on a 14 nm process at Intel. The process node difference is substantial: 6 nm versus 14 nm, which contributes to the AMD chip's ability to deliver competitive performance at a 28 W TDP against Intel's 125 W TDP.

Core and thread counts differ. AMD provides 8 cores and 16 threads, while Intel provides 10 cores and 20 threads. The Intel chip has a base clock of 3.70 GHz and a boost clock of 5.30 GHz, whereas the AMD chip runs at 2.70 GHz base and 4.75 GHz boost. The higher boost clock on Intel explains much of its single-thread advantage in Cinebench and Geekbench tests.

Cache configurations also differ. Both use 64 KB of L1 cache per core. The L2 cache is 512 KB per core on AMD versus 256 KB per core on Intel. The L3 cache is 16 MB shared on AMD versus 20 MB shared on Intel. The AMD die size is 208 mm², while the Intel die is 206 mm², nearly identical despite the different process nodes.

Memory support diverges sharply. The AMD chip supports DDR5 memory with dual-channel configuration and a memory bandwidth of 76.8 GB/s. The Intel chip supports DDR4 memory, also dual-channel, but with a memory bandwidth of 46.9 GB/s. The AMD chip supports ECC memory; the Intel chip does not. PCIe connectivity also differs: AMD provides Gen 4 with 20 lanes (CPU only), while Intel provides Gen 3 with 16 lanes (CPU only).

Integrated graphics differ as well. AMD includes the Radeon 680M, while Intel includes UHD Graphics 630. The AMD chip uses AMD Socket FP7, and the Intel chip uses Intel Socket 1200. The AMD part is a mobile market segment product, while the Intel part is a desktop segment product. The Intel multiplier is unlocked, while the AMD multiplier is locked.
