AMD Ryzen 5 7640HS vs Intel Core 9 273PTE Comparison

Where Each One Wins

The benchmark split favors the Intel Core 9 273PTE by a clear margin: 9 wins out of 15 head-to-head tests. However, the distribution of those wins tells a more nuanced story than the raw tally suggests. Intel's victories are concentrated in multithreaded rendering, physics simulation, floating-point math, and integer-heavy workloads. The AMD Ryzen 5 7640HS counters with wins in data compression, encryption, extended instruction throughput, random string sorting, and single-threaded performance.

For heavy parallel workloads, the Intel part is the obvious choice. The Cinebench R23 multicore result (20445 vs 12554) is a 62.9% advantage, and the R23 single-core result (2886 vs 1715.5) shows a 68.2% lead. These are not marginal differences. The Intel chip also dominates prime number finding (84.4% ahead), physics calculations (66% ahead), and floating-point math (34.2% ahead). Anyone running render farms, physics simulations, or scientific computing would see substantial gains.

The AMD part claims the efficiency-oriented and data-movement wins. It leads by 4% in data compression, 10.2% in data encryption, 22.4% in extended instructions, and 8.5% in random string sorting. Its single-thread PassMark result (3654 vs 3433) is 6% higher. These wins matter for database workloads, compression utilities, cryptographic tasks, and applications that rely on specialized instruction sets. The Ryzen 5 7640HS also holds a 4.7% edge in PassMark multithread? No, that is incorrect. The data shows Intel wins PassMark multithread 24054 vs 22979, a 4.7% delta. The AMD wins in single-thread PassMark.

The overall average benchmark scores place Intel slightly ahead (31143 vs 30390), which aligns with the 82nd vs 81st percentile ranking across all CPUs. In the nearest rival comparison, the Intel chip sits 0.2% above the Intel Core i7-12700F and 0.2% above the AMD Ryzen 9 8945HS, while the Ryzen 5 7640HS sits 0.1% above the AMD Ryzen 7 7736U. Both processors occupy a similar performance tier, but they achieve it through very different workloads.

Architecture Differences

The architectural gap between these two processors is substantial. The Intel Core 9 273PTE is built on Intel's 10 nm process at Intel's own foundry, using the Bartlett Lake codename. It belongs to the Core 9 generation and targets the desktop segment with an Intel Socket 1700. The AMD Ryzen 5 7640HS uses the Zen 4 architecture under the Phoenix codename, fabricated on TSMC's 4 nm node, and targets the mobile segment via AMD Socket FP8.

Core counts diverge sharply. Intel fields 12 cores and 24 threads, while AMD offers 6 cores and 12 threads. That doubling of threads explains much of Intel's multithreaded advantage. Cache hierarchies differ accordingly: Intel allocates 80 KB of L1 per core and 2 MB of L2 per core, with 36 MB of shared L3, whereas AMD uses 64 KB L1 per core, 1 MB L2 per core, and 16 MB of shared L3. The L3 deficit on the AMD side (16 MB vs 36 MB) is particularly relevant for workloads with large working sets.

Clock strategy differs too. The AMD part starts at a much higher base clock of 4.30 GHz versus Intel's 1.40 GHz, but Intel's boost clock reaches 5.50 GHz versus AMD's 5.00 GHz. The thermal design power reflects the market split: Intel is rated at 45 W, AMD at 35 W.

Memory support shows a generational divide. Intel supports both DDR4 and DDR5, while AMD supports DDR5 only. Both run dual-channel memory with an identical 89.6 GB/s peak bandwidth. Both support ECC memory. PCIe connectivity differs: Intel provides Gen 5 with 16 CPU lanes, AMD provides Gen 4 with 20 CPU lanes.

Integrated graphics also differ. Intel includes UHD Graphics 730, AMD includes Radeon 760M. The AMD transistor count is listed at 25,000 million across a 178 mm² die, while Intel does not report transistor or die size data. The AMD part carries three part numbers (FP7r2, FP7, and FP8 variants), reflecting its mobile flexibility, while Intel has a single part number.

Head-to-Head Benchmarks

The Cinebench suite delivers the most dramatic separation. In R23 multicore, Intel scores 20445 versus AMD's 12554, a 62.9% advantage. The single-core R23 result is even more lopsided: 2886 versus 1715.5, a 68.2% lead. The older R15 test shows the same pattern but with smaller margins: multicore 2060 versus 1978 (4.1% ahead) and single-core 290 versus 269.5 (7.6% ahead). The R23 results suggest that the newer benchmark exposes architectural efficiencies that the older test does not capture.

PassMark tests reveal a split personality. Intel wins floating-point math (60673 vs 45220, 34.2% ahead), integer math (82411 vs 73284, 12.5% ahead), prime number finding (142 vs 77, 84.4% ahead), physics (1917 vs 1155, 66% ahead), and multithread (24054 vs 22979, 4.7% ahead). AMD wins data compression (269524 vs 258704, 4% ahead), data encryption (15867 vs 14253, 10.2% ahead), extended instructions (20556 vs 15952, 22.4% ahead), random string sorting (31654 vs 28973, 8.5% ahead), and single-thread (3654 vs 3433, 6% ahead).

The pattern is consistent: Intel dominates raw compute throughput, AMD dominates data transformation and single-threaded agility. The extended instructions result is particularly telling. AMD's 22.4% edge suggests the Zen 4 architecture handles AVX-style workloads more efficiently. Data encryption and compression wins reinforce that interpretation, as those workloads rely heavily on specialized instruction paths. The single-thread PassMark win (3654 vs 3433) shows AMD's higher base clock translates into snappier single-thread responsiveness in certain workloads, even though Intel wins Cinebench single-core tests.

The Verdict

The data points to a clear division of labor. The Intel Core 9 273PTE is the compute powerhouse, winning 9 of 15 head-to-head tests with particularly decisive margins in rendering, physics, floating-point math, and prime number workloads. Its 12 cores and 24 threads, combined with 36 MB of L3 cache and a 5.50 GHz boost clock, deliver the kind of parallel throughput that content creators, engineers, and data scientists require. The 62.9% Cinebench R23 multicore lead is the single most important number in this comparison.

The AMD Ryzen 5 7640HS is the specialized utility player. Its wins in data compression, encryption, extended instructions, and random string sorting suggest it handles data-centric workloads more efficiently. The 22.4% extended instructions lead and the 6% single-thread PassMark advantage indicate an architecture that responds quickly to instruction-heavy tasks. The 35 W TDP also positions it as the lower-power option, though thermal comparisons are not directly measured here.

For buyers choosing between these two, the decision hinges on workload composition. Multithreaded rendering, physics simulation, and general compute favor Intel by margins that range from 4.7% to 84.4%. Data transformation, encryption, and specialized instruction workloads favor AMD by margins from 4% to 22.4%. The Intel chip pairs with DDR4 or DDR5 memory, while the AMD chip requires DDR5. Intel offers PCIe Gen 5 but fewer lanes (16), while AMD offers PCIe Gen 4 with more lanes (20). The Intel chip carries a $549 launch MSRP, while the AMD chip has no reported launch price.

The average benchmark scores place Intel 2.4% ahead overall (31143 vs 30390), but that aggregate hides the workload-specific strengths. A user who primarily runs compression and encryption tools would likely prefer the AMD chip's 4% to 10.2% leads. A user who renders frames or runs simulations would see the Intel chip's 34.2% to 84.4% advantages as decisive. The percentile rankings (82nd for Intel, 81st for AMD) confirm these are closely matched processors overall, with the difference emerging from which workloads matter most to the user.
