Analysis: AMD Ryzen 5 7500X3D vs AMD Ryzen 7 PRO 8840HS
Where Each One Wins
The recorded benchmark data splits the two processors into distinct usage profiles. The AMD Ryzen 5 7500X3D wins 2 of the 11 head-to-head tests, while the AMD Ryzen 7 PRO 8840HS wins 9. Those wins are not evenly distributed across workload types, which makes the division informative rather than merely lopsided.
The Ryzen 5 7500X3D takes both of its victories in tests that stress prime number generation and physics simulation. The find prime numbers test shows the 7500X3D at 221 versus 84 for the 8840HS, a delta of 163.1 percent. The physics test shows 2779 versus 1351, a delta of 105.7 percent. Both are more than double the rival's score. These are integer-heavy, latency-sensitive workloads where the 7500X3D's large shared L3 cache appears to provide a decisive advantage.
The Ryzen 7 PRO 8840HS wins the remaining categories, including all of the throughput-oriented tests. Its largest margins come in integer math (93342 versus 70774, a delta of -24.2 percent from the 7500X3D's perspective) and floating point math (55739 versus 43594, a delta of -21.8 percent). It also wins data compression (311199 versus 271649, -12.7 percent), data encryption (18838 versus 15797, -16.1 percent), extended instructions (22298 versus 20455, -8.3 percent), random string sorting (37922 versus 32999, -13 percent), multithread (26646 versus 25047, -6 percent), and single thread (3692 versus 3494, -5.4 percent).
The use-case split is therefore clear: the 7500X3D leads in specialized, cache-sensitive physics and prime workloads, while the 8840HS leads in general computing, encryption, compression, and both single-threaded and multithreaded aggregate performance.
Architecture Differences
Both processors are built by AMD and use Zen 4 cores, but they differ substantially in packaging, process node, and cache structure. The Ryzen 5 7500X3D is a desktop part from the 7000 series, codenamed Raphael, manufactured on a 5 nm process at TSMC. The Ryzen 7 PRO 8840HS is a mobile part from the 8000 series, codenamed Hawk Point, manufactured on a 4 nm process at TSMC. The process node difference is one nanometer, and the transistor counts reflect that separation: the 7500X3D contains 11,270 million transistors on a 71 mm² die, while the 8840HS contains 25,000 million transistors on a 178 mm² die.
The cache hierarchy is where the two diverge most sharply. The 7500X3D has 64 KB of L1 per core, 1 MB of L2 per core, and 96 MB of shared L3. The 8840HS also has 64 KB of L1 per core and 1 MB of L2 per core, but only 16 MB of shared L3. That 80 MB difference in shared L3 is the defining architectural gap between the two, and it explains why the 7500X3D dominates in cache-sensitive tests such as find prime numbers and physics.
Core counts also differ. The 7500X3D has 6 cores and 12 threads, while the 8840HS has 8 cores and 16 threads. The 8840HS therefore has two additional cores and four additional threads, which contributes to its wins in multithread and math throughput tests. The 7500X3D runs at a base clock of 4.00 GHz and a boost clock of 4.50 GHz, whereas the 8840HS runs at a base clock of 3.30 GHz and a boost clock of 5.10 GHz. The higher boost clock on the 8840HS helps explain its single-thread win.
Thermal design power differs by more than a factor of two. The 7500X3D is rated at 65 W TDP, while the 8840HS is rated at 28 W TDP. The 8840HS achieves its higher core count and higher boost clock within a much lower power envelope, reflecting the efficiency of the 4 nm process and the mobile-oriented design. The 7500X3D uses AMD Socket AM5, while the 8840HS uses AMD Socket FP7. Memory support is DDR5 for both, with dual-channel buses. The 7500X3D has a memory bandwidth of 83.2 GB/s, while the 8840HS has 89.6 GB/s. Both support ECC memory. The 7500X3D uses PCIe Gen 5 with 24 lanes (CPU only), while the 8840HS uses PCIe Gen 4 with 20 lanes (CPU only). Integrated graphics differ as well: the 7500X3D carries Radeon Graphics, while the 8840HS carries the Radeon 780M.
Neither processor has an unlocked multiplier. The 7500X3D has a launch MSRP of $269; the 8840HS has no recorded launch MSRP.
Head-to-Head Benchmarks
The largest single win in the head-to-head set belongs to the Ryzen 5 7500X3D in the find prime numbers test. Its score of 221 versus 84 for the 8840HS represents a 163.1 percent advantage. This is the kind of workload where the 96 MB shared L3 cache allows the 7500X3D to keep far more working data resident on-die, avoiding repeated memory accesses. The physics test shows the same pattern, with the 7500X3D scoring 2779 versus 1351, a 105.7 percent margin. Both wins are by more than double.
The Ryzen 7 PRO 8840HS answers with a broad set of wins, but the largest margins come in the math tests. In integer math, the 8840HS scores 93342 against 70774, a 24.2 percent advantage. In floating point math, it scores 55739 against 43594, a 21.8 percent advantage. These are the two biggest wins for the 8840HS in percentage terms, and they align with its extra two cores and four threads.
Data encryption shows a 16.1 percent edge for the 8840HS (18838 versus 15797), and data compression shows a 12.7 percent edge (311199 versus 271649). Random string sorting goes to the 8840HS by 13 percent (37922 versus 32999). Extended instructions favor the 8840HS by 8.3 percent (22298 versus 20455). The multithread test favors the 8840HS by 6 percent (26646 versus 25047), which is a smaller margin than the core count difference might suggest, likely due to the 7500X3D's cache advantage offsetting some of the 8840HS's core advantage. Single-thread performance favors the 8840HS by 5.4 percent (3692 versus 3494), consistent with its higher boost clock of 5.10 GHz versus 4.50 GHz.
The average benchmark scores place the two close together overall. The 7500X3D has an average benchmark score of 44573 and sits at the 89th percentile among all CPUs. The 8840HS has an average benchmark score of 39603 and sits at the 87th percentile. The 7500X3D's nearest rivals include the Intel Core Ultra X9 388H (delta 0.2 percent), Intel Core i9-13950HX (delta 0.5 percent), AMD Ryzen AI Max 385 (delta 0.6 percent), and Intel Core i5-14600 (delta -0.7 percent). The 8840HS's nearest rivals include the AMD Ryzen AI 7 450 (delta 0.3 percent), AMD Ryzen 7 9800X3D (delta -0.4 percent), AMD Ryzen 7 PRO 8845HS (delta 0.7 percent), and AMD EPYC 4245P (delta 1 percent). The data indicates the 7500X3D holds a slight overall average-score edge of about 4970 points, roughly 12.5 percent, despite losing most individual tests.

The Verdict
The data supports a straightforward selection based on workload. The AMD Ryzen 5 7500X3D is the choice for tasks dominated by cache-sensitive integer workloads. Its 163.1 percent win in find prime numbers and 105.7 percent win in physics are the largest margins in the entire head-to-head set. The 96 MB shared L3 cache is the clear driver of these results. It also holds a higher average benchmark score (44573 versus 39603) and a higher percentile ranking (89 versus 87), despite being a desktop part with a 65 W TDP.
The AMD Ryzen 7 PRO 8840HS is the choice for general-purpose and throughput-oriented computing. It wins integer math by 24.2 percent, floating point math by 21.8 percent, data compression by 12.7 percent, data encryption by 16.1 percent, random string sorting by 13 percent, extended instructions by 8.3 percent, multithread by 6 percent, and single-thread by 5.4 percent. Its 8 cores and 16 threads, combined with a 5.10 GHz boost clock and 4 nm process, deliver broad superiority across most recorded tests while operating within a 28 W TDP.
For a user prioritizing physics simulation or prime-heavy computation, the 7500X3D delivers double the performance in those specific tests. For a user prioritizing mixed workloads, encryption, compression, and math throughput, the 8840HS is ahead in nearly every other category. The 8840HS also offers the Radeon 780M integrated graphics, a more advanced process node, and a lower power envelope, making it the more versatile processor in the recorded data.
