AMD Ryzen 5 PRO 9645 vs Intel Core 7 253PQE Comparison

Head-to-Head Benchmarks

The benchmark data presents a clear split between these two processors. The Intel Core 7 253PQE dominates the multithreaded and heavy compute workloads, while the AMD Ryzen 5 PRO 9645 claims victory in the single-threaded and prime-number tests. Of the 11 recorded head-to-head comparisons, Intel wins 8 and AMD wins 3, but the margin of victory matters more than the count.

Starting with the biggest Intel advantage: floating point math. The Intel Core 7 253PQE scores 105279 against AMD's 62720, a 67.9% lead. This is the largest delta in the entire comparison. Physics simulation follows closely, with Intel scoring 2970 versus AMD's 1945, a 52.7% advantage. Integer math also goes firmly Intel's way, 137795 to 93019, a 48.1% gap. These three results indicate that the Intel part is substantially stronger in raw arithmetic throughput and physics-based workloads.

Data encryption shows an even more striking divide. Intel scores 25515, AMD scores 17599, giving Intel a 45% lead. Data compression follows the same pattern: Intel at 487335, AMD at 363736, a 34% advantage. Random string sorting also favors Intel heavily, 54222 versus 38410, a 41.2% delta. The multithread score sums up the overall thread-heavy performance: Intel hits 41656, AMD reaches 31434, a 32.5% gap.

Extended instructions are closer. Intel scores 32390, AMD scores 29705, with Intel ahead by 9%. This is the narrowest Intel win in the entire dataset, suggesting that the AMD part holds up reasonably well when the workload is instruction-set specific but not purely arithmetic.

The AMD wins are fewer but notable. In the single-thread test, AMD scores 4636 against Intel's 4389, a 5.3% lead. This appears twice in the data (as passmark_single_thread and passmark_singlethread, both identical), confirming the result. The other AMD victory is in find prime numbers, where AMD scores 235 versus Intel's 206, a 12.3% advantage. This is a specialized workload that rewards the AMD architecture's integer division and branch handling.

Looking at the broader averages, the AMD Ryzen 5 PRO 9645 actually posts a higher average benchmark score of 58916 compared to Intel's 55919. The AMD part sits at the 92nd percentile of all CPUs, while Intel sits at the 91st. This apparent contradiction with the head-to-head results comes from the fact that the averages include a wider set of tests beyond the direct comparisons. The AMD part's nearest rivals include the AMD Ryzen AI 9 HX 470 (0.2% above), Intel Xeon w5-2545 (0.7% below), AMD Ryzen 7 9850X3D (0.9% below), and Intel Xeon Platinum 8260M (1% below). The Intel part's nearest rivals include the Intel Core i9-14900HX (0.2% above), AMD Ryzen AI Max 390 (0.6% above), AMD Ryzen AI 9 HX PRO 470 (0.7% above), and AMD Ryzen Threadripper PRO 3955WX (1.1% above). Both processors are clustered tightly with their peers, within roughly a percentage point either way.

The Verdict

The data points to two different buyers. The Intel Core 7 253PQE is the choice for anyone whose workloads are heavily parallel and arithmetic-intensive. The 34% to 67.9% leads in compression, encryption, floating point, integer math, physics, and multithread performance are not marginal; they are decisive. If the daily driver is rendering, simulation, data compression, or any task that scales across cores, the Intel part wins outright in the recorded benchmarks.

The AMD Ryzen 5 PRO 9645 is the pick for single-threaded responsiveness and specific math workloads. Its 5.3% single-thread advantage and 12.3% prime-number advantage suggest that lightly threaded applications, interactive workloads, and certain computational tasks will feel snappier on the AMD part. The higher average benchmark score (58916 versus 55919) and the higher percentile (92 versus 91) also indicate that the AMD part is the more balanced overall performer when considering a broader test suite.

Neither processor is a clear winner for every scenario. The Intel part's 10 cores and 20 threads give it a structural advantage in parallel work, while the AMD part's 6 cores and 12 threads, paired with a higher boost clock in single-thread tests, give it the edge where fewer threads matter. The recorded data does not support a universal recommendation; it supports a workload-based decision.

Where Each One Wins

The Intel Core 7 253PQE wins in every category that involves sustained multithreaded execution or heavy arithmetic. Data compression, encryption, floating point math, integer math, physics simulation, random string sorting, and the overall multithread score all go to Intel with deltas ranging from 32.5% to 67.9%. This makes it the obvious candidate for video encoding, 3D rendering, scientific computing, database workloads, and any batch processing that can utilize 20 threads. The 34% compression lead and 45% encryption lead specifically point to file archiving and security applications as strong use cases.

The AMD Ryzen 5 PRO 9645 wins where the workload is single-threaded or specialized toward prime number computation. The 5.3% single-thread lead makes it better for legacy applications, spreadsheet macros, browser-based tasks, and any software that does not scale well across cores. The 12.3% prime number lead suggests that number theory computations, cryptographic key generation, and certain mathematical software will run faster on the AMD part. The AMD part also carries a higher average benchmark score, meaning that in a mixed workload environment, the AMD chip may deliver more consistent overall performance.

For a system that primarily runs one heavy multithreaded app, the Intel part is the clear winner. For a system that runs many small, interactive tasks or specialized math workloads, the AMD part holds the advantage. The data does not support a middle-ground compromise; the strengths are too polarized.
