AMD Ryzen 5 7500X3D vs AMD Ryzen 7 PRO 8845HS Comparison

Head-to-Head Benchmarks

The recorded data shows a clear overall victory for the AMD Ryzen 7 PRO 8845HS, which takes 9 of the 11 compared tests. The AMD Ryzen 5 7500X3D claims only 2 wins, but those two wins are dramatic and point to a specific strength. The most lopsided result in the entire comparison is the PassMark find prime numbers test, where the 7500X3D scores 221 against the 8845HS's 87, a 154% advantage. This is a massive margin and indicates a pronounced capability in single-threaded prime calculation workloads.

The other win for the 7500X3D comes in the PassMark physics test, where it scores 2779 compared to the 8845HS's 1389. That 100.1% lead means the desktop chip more than doubles the mobile part's physics score. These two victories share a common theme: they are both workloads that typically rely on high per-core performance with limited thread scaling. The 7500X3D's 4.50 GHz boost clock and its large 96 MB L3 cache likely contribute to these results.

Every other benchmark in the head-to-head set goes to the Ryzen 7 PRO 8845HS. The largest margin for the mobile chip is in PassMark integer math, where it scores 97625 against 70774, a 27.5% lead. Floating point math follows closely, with the 8845HS scoring 58965 versus 43594, a 26.1% edge. Data encryption shows a 22.9% advantage for the 8845HS (20487 versus 15797), and random string sorting shows a 21.2% lead (41867 versus 32999). Data compression also favors the 8845HS by 21%, with scores of 343952 and 271649 respectively.

Extended instructions see the 8845HS ahead by 19.6%, scoring 25434 against 20455. The multithread score, which is a broad measure of overall parallel throughput, also goes to the 8845HS by a 12.3% margin, with 28572 versus 25047. The smallest victory for the 8845HS is in single-thread performance, where it scores 3762 against 3494, a 7.1% lead. This single-thread result is notable because it shows the mobile chip is faster even in a test that usually favors desktop parts with higher boost clocks.

The pattern is consistent: the 7500X3D dominates in very specific, latency-sensitive single-threaded workloads, while the 8845HS wins broadly across general compute, encryption, compression, and math tests. The average benchmark score reflects this split. The 7500X3D averages 44573, while the 8845HS averages 39325. However, the head-to-head deltas show the 8845HS winning most direct comparisons, which suggests the average score calculation weights the two outlier wins of the 7500X3D differently than the direct test set does.

The Verdict

The data indicates two distinct usage profiles. The AMD Ryzen 5 7500X3D is for workloads that are sensitive to large cache and high per-core throughput in very specific math and physics simulations. Its 154% lead in find prime numbers and 100.1% lead in physics are not minor edges; they are dominant. Anyone running those exact types of single-threaded calculations should favor the 7500X3D. Its 96 MB L3 cache is exceptionally large compared to the 8845HS's 16 MB, and the benchmark results show that this cache advantage translates directly into wins in cache-heavy tests.

The AMD Ryzen 7 PRO 8845HS is the better general-purpose processor. It wins the multithread test by 12.3%, integer math by 27.5%, floating point math by 26.1%, and data encryption by 22.9%. It also wins single-thread by 7.1%, which is surprising given its lower base clock of 3.80 GHz versus 4.00 GHz for the 7500X3D. However, its higher boost clock of 5.10 GHz likely explains this. The 8845HS also has two more cores and four more threads, which explains its broad wins in parallel workloads. Its 45W TDP makes it the more power-efficient option on paper.

The benchmark data does not support picking the 7500X3D for general productivity or mixed workloads. Its only wins are in two narrow tests. The 8845HS wins 9 of 11 direct comparisons. The single-thread win for the 8845HS is particularly important because it removes the typical argument for the desktop chip. If the mobile part is faster even in single-thread, the 7500X3D only makes sense for users who specifically run prime number calculations or physics simulations and nothing else.

Where Each One Wins

The 7500X3D wins in exactly two recorded tests: find prime numbers and physics. These are both specialized workloads that benefit from its 96 MB L3 cache. The prime number test shows a 154% lead, which is the single largest delta in the entire comparison. The physics test shows a 100.1% lead, doubling the 8845HS's score. For users running those specific calculations, the 7500X3D is the clear choice. The desktop chip also has a higher base clock (4.00 GHz versus 3.80 GHz), which may help in latency-sensitive tasks that do not boost for long periods.

The 8845HS wins in every other tested category. It is faster in data compression, data encryption, extended instructions, floating point math, integer math, multithread, random string sorting, and single-thread. Its 8 cores and 16 threads give it a structural advantage in parallel workloads. Its 5.10 GHz boost clock gives it a single-thread edge despite the lower base clock. Its memory bandwidth of 89.6 GB/s exceeds the 7500X3D's 83.2 GB/s, which likely contributes to its wins in memory-intensive tests. Its 4 nm process node and higher transistor count suggest a more complex design that handles a broader range of instructions efficiently.

The 8845HS also wins the multithread test by 12.3%, which is the most important general-purpose metric. A user running rendering, compilation, or data processing tasks should expect the 8845HS to finish faster. The 7500X3D's average benchmark score of 44573 is higher than the 8845HS's 39325, but that average is skewed by the two massive wins in prime numbers and physics. The direct head-to-head results show a 9 to 2 split in favor of the 8845HS. The 8845HS's percentile ranking of 86 is close to the 7500X3D's 89, but the direct comparisons show a consistent edge for the mobile chip in most real-world scenarios.
