AMD Ryzen 5 PRO 8645HS vs Intel Core 7 253PQE Comparison

The Verdict

The benchmark data is unambiguous. The Intel Core 7 253PQE wins every single recorded head-to-head test, 17 out of 17. The AMD Ryzen 5 PRO 8645HS does not win a single comparison. This is not a close contest; the performance gap is consistent and often large.

The Intel Core 7 253PQE is the clear choice for anyone building a desktop system where raw computing power is the priority. It delivers substantially higher scores in every workload category, from single-threaded tasks to heavily multithreaded rendering. Its nearest rivals in the database include the Intel Core i9-14900HX, with the Core 7 253PQE scoring 0.2% lower on average, placing it in extremely fast company. It sits at the 91st percentile of all CPUs in the database.

The AMD Ryzen 5 PRO 8645HS, conversely, is a mobile processor. Its nearest rivals include the AMD Ryzen 7 8700F and AMD Ryzen 9 8945HS, with only a 0.6% difference in average score, placing it at the 82nd percentile. For a 6-core mobile chip, that is a respectable position. However, in a direct comparison against the Intel chip, the data shows no scenario where the AMD part comes out ahead. The only advantage the AMD chip holds is qualitative: it is built for a different form factor and power envelope. The data shows the Intel part is faster, but the AMD part is the only one of the two designed for mobile use.

Architecture Differences

The two processors come from different design philosophies and manufacturing processes. The AMD Ryzen 5 PRO 8645HS uses the Zen 4 architecture on a 4 nm process node from TSMC. Its codename is Hawk Point, and it belongs to the 8000 series. The chip contains 25,000 million transistors on a 178 mm² die. In contrast, the Intel Core 7 253PQE uses the Bartlett Lake architecture on a 10 nm process node from Intel, and no transistor or die size data is recorded for it.

The cache hierarchies are notably different. The AMD chip allocates 64 KB of L1 cache per core, 1 MB of L2 per core, and 16 MB of shared L3 cache. The Intel chip uses a larger cache structure: 80 KB of L1 per core, 2 MB of L2 per core, and a much larger 33 MB of shared L3 cache. This larger cache pool likely contributes to the Intel part's strong single-threaded performance.

The integrated graphics also differ. The AMD Ryzen 5 PRO 8645HS uses a Radeon 760M, while the Intel Core 7 253PQE uses UHD Graphics 770. The database does not record performance results for these iGPUs, so no direct comparison can be made on that front.

The AMD part is a mobile processor (market segment is Mobile) that uses AMD Socket FP7. The Intel part is a desktop processor that uses Intel Socket 1700. This is a fundamental architectural distinction. The AMD chip is built for the power and thermal constraints of laptops, while the Intel chip is designed for desktop power delivery and cooling.

Specification Differences

The most visible difference is in core count. The Intel Core 7 253PQE offers 10 cores and 20 threads versus 6 cores and 12 threads for the AMD Ryzen 5 PRO 8645HS. Clock speeds favor Intel as well: base clock of 3.50 GHz versus 4.30 GHz for AMD, but boost clock of 5.70 GHz versus 5.00 GHz for AMD. The Intel chip has a higher top clock, while the AMD chip has a higher base clock.

Power draw is drastically different. The Intel Core 7 253PQE has a TDP of 125 watts, while the AMD Ryzen 5 PRO 8645HS has a TDP of 45 watts. This reflects the mobile versus desktop design split. Memory support differs: the AMD chip supports DDR5 only, while the Intel chip supports both DDR4 and DDR5. Both use a dual-channel memory bus with an identical recorded memory bandwidth of 89.6 GB/s.

PCIe connectivity is a major difference. The AMD Ryzen 5 PRO 8645HS uses PCIe Gen 4 with 20 CPU-only lanes. The Intel Core 7 253PQE uses PCIe Gen 5 with 16 CPU-only lanes. The Intel part offers a newer PCIe standard, while the AMD part offers more lanes. The Intel part is the only one with a recorded launch MSRP of $409.

The AMD chip is manufactured by TSMC at 4 nm, while Intel fabricates its own chip at 10 nm. The AMD part has a production status of Active, as does the Intel part. The Intel part has a later release date, 2026-03-08, compared to the AMD's 2024-04-15.

Head-to-Head Benchmarks

The Intel Core 7 253PQE dominates every benchmark in the database. The closest contest is in PassMark single-thread, where the Intel part scores 4389 versus the AMD's 3858, a margin of 12.1%. This is the only test where the gap is in the low double digits. Every other test shows a gap of at least 31.9%.

In the Cinebench suite, the Intel part is consistently faster by 37.1% to 37.2%. For Cinebench R23 multicore, the Intel score is 31390 versus the AMD's 19742. For Cinebench R23 singlecore, the Intel score is 4431 versus 2787. The pattern repeats across R15 and R20, with the Intel part winning both multicore and singlecore by the same approximate margin.

The PassMark tests reveal the widest gaps. The largest delta is in find prime numbers, where the Intel part scores 206 versus the AMD's 73, a difference of 64.6%. Floating point math shows a 56.8% gap (105279 versus 45481). Physics scores show a 59.3% gap (2970 versus 1208). These are massive performance differences.

Data compression shows a 45.5% gap (487335 versus 265826). Integer math shows a 47.2% gap (137795 versus 72740). Multithread scores show a 43.4% gap (41656 versus 23569). Data encryption shows a 31.9% gap (25515 versus 17387). Extended instructions show a 34.5% gap (32390 versus 21212). Random string sorting shows a 34.6% gap (54222 versus 35472).

The consistency of the Intel lead is notable. Whether the workload is single-threaded, multithreaded, integer-heavy, or floating-point-heavy, the Intel Core 7 253PQE is faster. The AMD chip does not come out ahead in any recorded test.

Where Each One Wins

Based strictly on the recorded data, the Intel Core 7 253PQE wins in every measurable performance category. There are zero wins for the AMD Ryzen 5 PRO 8645HS in the head-to-head benchmark set. The Intel part is the winner for any workload that relies on raw CPU throughput: rendering, compression, encryption, prime number finding, floating point math, integer math, physics calculations, and string sorting.

The AMD Ryzen 5 PRO 8645HS has no benchmark wins to point to. Its advantages are structural rather than performance-based. It is a mobile processor with a 45 watt TDP, which is 80 watts lower than the Intel part's TDP. It uses AMD Socket FP7, which is a laptop socket. It has a smaller process node at 4 nm versus 10 nm, which typically indicates better power efficiency per watt, though no efficiency benchmarks are recorded in the database.

The AMD chip also has a higher base clock of 4.30 GHz versus 3.50 GHz, and it offers more PCIe lanes at Gen 4 (20 lanes) versus Gen 5 (16 lanes). For a mobile user who needs a laptop processor, the AMD Ryzen 5 PRO 8645HS is the only viable option between these two, since the Intel part is a desktop chip. For a desktop builder, the Intel Core 7 253PQE is the clear winner on every recorded benchmark score.

The data shows a decisive victory for the Intel part. The average benchmark score of 55919 places it at the 91st percentile, while the AMD's 30879 places it at the 82nd percentile. The Intel part's closest rival in the database is the Intel Core i9-14900HX, and it trails that chip by only 0.2%. The AMD part's closest rival is the AMD Ryzen 7 8700F, and it leads that chip by 0.4%. The performance class difference is clear.
