AMD Ryzen 7 7745HX vs Intel Xeon 6353P Comparison

Where Each One Wins

The benchmark split between the Intel Xeon 6353P and the AMD Ryzen 7 7745HX is not evenly distributed. The AMD part wins 9 of the 15 recorded head-to-head comparisons, while the Intel part takes 6. The nature of those wins, however, is sharply divided along workload type.

The AMD Ryzen 7 7745HX dominates throughput-oriented tasks. It wins data compression by 25.5%, data encryption by 33.7%, extended instructions by 36.8%, integer math by 17.9%, and multithread workloads by 20.3%. It also takes floating point math, though by a narrow 1.2% margin, plus prime number finding and random string sorting. These are the kinds of workloads that scale with raw core efficiency and memory bandwidth, and the data shows the AMD part holding a consistent advantage.

The Intel Xeon 6353P wins in single-threaded and lightly threaded scenarios. It leads in Cinebench R15 single-core by 6.3%, Cinebench R23 single-core by 68.3%, PassMark single-thread by 7.1%, and PassMark physics by 8.7%. Its most decisive victory is in Cinebench R23 multicore, where it beats the AMD part by 19.5%, a notable outlier given the AMD part's otherwise strong multithread showing.

The practical split is clear: the AMD processor is the better all-round compute engine for parallel workloads, while the Intel processor excels at single-thread responsiveness and shows surprising strength in one specific multi-core render test. For users running heavily threaded applications like encryption, compression, or integer-heavy calculations, the AMD part is the stronger choice. For single-thread-bound software or physics simulations, the Intel part takes the lead.

Architecture Differences

The two processors come from fundamentally different design philosophies. The Intel Xeon 6353P is built on Raptor Lake, specifically the Raptor Lake-R refresh, using Intel's 10 nm process with a 257 mm² die. The AMD Ryzen 7 7745HX uses Zen 4 architecture on the Dragon Range codename, fabricated by TSMC at 5 nm with a 71 mm² die and 6,570 million transistors. The process node difference is significant: the AMD chip packs far more transistors into a much smaller area.

Both processors have 8 cores and 16 threads, so the core count is identical. The differences lie in clock speeds, cache hierarchy, and platform features. The Intel part runs at a base clock of 2.70 GHz with a boost of 5.40 GHz, while the AMD part has a higher base of 3.60 GHz but a lower boost of 5.10 GHz. The Intel chip's higher boost clock helps explain its single-thread wins, while the AMD chip's higher base clock contributes to sustained throughput.

Cache configurations differ markedly. The Intel Xeon 6353P has 80 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3. The AMD Ryzen 7 7745HX has 64 KB of L1 per core, 1 MB of L2 per core, and a larger 32 MB of shared L3. The AMD part's larger L3 cache likely aids its performance in data-heavy workloads.

Platform support also diverges. The Intel part supports both DDR4 and DDR5 memory on a dual-channel bus, while the AMD part supports only DDR5 but lists an official memory bandwidth of 83.2 GB/s. Both support ECC memory. The Intel part uses Intel Socket 1700 with 16 PCIe Gen 5 lanes, while the AMD part uses AMD Socket FL1 with 28 PCIe Gen 5 lanes. The AMD part includes a Radeon 610M integrated GPU; the Intel part has no integrated graphics. The Intel part has a 65 W TDP, the AMD part a 55 W TDP, and the AMD part has an unlocked multiplier while the Intel part does not.

Head-to-Head Benchmarks

The largest single win for the Intel Xeon 6353P is in Cinebench R23 single-core, where it scores 3114 against the AMD part's 1850, a 68.3% advantage. That is an enormous gap and indicates a substantial difference in single-thread performance. The Intel part also wins Cinebench R23 multicore with 22058 versus 18452.5, a 19.5% lead. In Cinebench R15 single-core, the Intel part leads 313 to 294.5, a 6.3% margin, and in PassMark physics it leads 1845 to 1697, an 8.7% margin. PassMark single-thread goes to the Intel part at 4226 versus 3947, a 7.1% lead.

The AMD Ryzen 7 7745HX's biggest win is in PassMark extended instructions, where it scores 28966 against the Intel part's 18311, a 36.8% advantage. Data encryption goes to the AMD part by 33.7% (22967 versus 15228). Random string sorting is won by the AMD part by 29.8% (44474 versus 31226). Data compression goes to the AMD part by 25.5% (383322 versus 285581). PassMark multithread shows the AMD part ahead by 20.3% (32581 versus 25951). Integer math goes to AMD by 17.9% (105773 versus 86836), and prime number finding goes to AMD by 18.6% (156 versus 127). Floating point math is nearly even, with AMD winning 64297 versus 63509, a 1.2% edge.

The pattern is consistent: the Intel part wins where single-thread performance or specific physics workloads matter, while the AMD part wins across a broad range of parallel and data-intensive tasks. The Cinebench R23 multicore result for Intel is an exception to this pattern, and it is importantly the AMD part wins the older Cinebench R15 multicore test by 25.6%, scoring 2986 versus 2223. The two multicore render tests disagree, which suggests workload-specific sensitivity within the render suite.

The Verdict

The data paints a clear picture for different user profiles. The AMD Ryzen 7 7745HX is the better choice for parallel workloads: it wins 9 of 15 head-to-head tests, and its victories in encryption, compression, integer math, and extended instructions come by substantial double-digit margins. The larger 32 MB L3 cache and higher base clock of 3.60 GHz support its strong throughput performance. For users running data-heavy, multithreaded applications, the AMD part is the superior option.

The Intel Xeon 6353P is the better choice for single-thread-bound workloads. Its 68.3% lead in Cinebench R23 single-core is decisive, and it also wins PassMark single-thread and physics tests. The higher boost clock of 5.40 GHz clearly helps in these scenarios. The Intel part's 19.5% win in Cinebench R23 multicore is a notable data point, but it is contradicted by the AMD part's 25.6% win in Cinebench R15 multicore, so render workloads do not consistently favor Intel.

Platform considerations also matter. The Intel Xeon 6353P is a server/workstation part with a launch MSRP of $426, uses Intel Socket 1700, and supports both DDR4 and DDR5. The AMD Ryzen 7 7745HX is a mobile part with a 55 W TDP versus the Intel part's 65 W, supports only DDR5 but lists a higher memory bandwidth of 83.2 GB/s, offers 28 PCIe Gen 5 lanes versus 16, and includes integrated graphics. The AMD part is also unlocked for overclocking.

The average benchmark scores nearly tie: the Intel part has an average of 33844 with a percentile of 84, while the AMD part has an average of 33091 with a percentile of 83. The Intel part sits near rivals like the Intel Core i7-12800HX (within 0.1%) and AMD Ryzen 9 3900XT (ahead by 0.3%). The AMD part sits within 0% of the Intel Core i7-13650HX and AMD Ryzen 7 8700G, and within 0.3% of the AMD Ryzen 9 PRO 6950H. Neither processor distances the other in overall average score.

The practical verdict: choose the AMD Ryzen 7 7745HX for multithreaded compute, encryption, compression, and integer-heavy tasks. Choose the Intel Xeon 6353P for single-thread performance, physics simulations, and the specific Cinebench R23 multicore workload where it shows a large lead.
