AMD Ryzen 5 PRO 8640HS vs Intel Core 7 253PTE Comparison

The AMD Ryzen 5 PRO 8640HS and Intel Core 7 253PTE occupy different corners of the processor market, one a 28-watt mobile chip and the other a 45-watt desktop part. The benchmark data shows a clear overall winner, but the AMD chip holds specific advantages that matter for certain workloads.

Head-to-Head Benchmarks

The Intel Core 7 253PTE dominates the head-to-head results, winning 15 of 17 recorded tests. The most lopsided victories come in PassMark integer math, where Intel scores 119,552 against AMD's 69,839, a 41.6% advantage. Floating point math shows a similar gap: Intel scores 67,209 versus 43,019, which is 36% higher. These are heavy compute workloads that scale with core count and thread count, and Intel's 10 cores and 20 threads outmatch AMD's 6 cores and 12 threads.

Cinebench results are consistent across all three versions. In Cinebench R23 multi-core, Intel scores 21,276 versus AMD's 18,104, a 14.9% lead. The same 14.9% delta appears in R20 multi-core (8,935 vs 7,603) and R15 multi-core (2,144 vs 1,824). Single-core Cinebench tests also show Intel ahead by 14.9%: R23 single-core is 3,003 versus 2,555, R20 single-core is 1,261 versus 1,073, and R15 single-core is 302 versus 257. Intel's higher boost clock of 5.40 GHz versus 4.90 GHz contributes to these single-thread wins.

PassMark multi-thread shows Intel ahead 25,031 to 21,465, a 14.2% margin. Data compression follows at 275,828 versus 246,446 (10.7% higher for Intel), and prime number finding is 82 versus 71, a 13.4% gap. Physics simulation also favors Intel: 1,318 versus 1,043, which is 20.9% higher. Data encryption is close, with Intel at 15,500 versus AMD's 14,962, only a 3.5% lead. PassMark single-thread confirms Intel's edge: 3,794 versus 3,561, a 6.1% difference.

The AMD Ryzen 5 PRO 8640HS wins only two tests, but they are notable. PassMark extended instructions shows AMD at 18,507 versus Intel's 17,099, an 8.2% advantage. Random string sorting also goes to AMD: 30,235 versus 28,227, a 7.1% lead. These wins suggest AMD's Zen 4 architecture handles certain instruction patterns and memory-access workloads more efficiently despite having fewer cores.

Architecture Differences

The two processors come from fundamentally different design philosophies. AMD's Ryzen 5 PRO 8640HS uses the Zen 4 architecture, codenamed Hawk Point, built on a 4 nm process at TSMC. It integrates 25,000 million transistors on a 178 mm² die. Intel's Core 7 253PTE uses Bartlett Lake, built on a 10 nm process at Intel's own foundries. The database does not record transistor count or die size for the Intel part.

Core configurations differ sharply. AMD offers 6 cores and 12 threads, while Intel provides 10 cores and 20 threads. Base clocks are far apart: AMD runs at 3.50 GHz, Intel at 1.80 GHz. Boost clocks reverse the order: AMD reaches 4.90 GHz, Intel goes to 5.40 GHz. Thermal design power also separates them, with AMD rated at 28 watts and Intel at 45 watts.

Cache hierarchies show distinct approaches. AMD allocates 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. Intel uses 80 KB of L1 per core, 2 MB of L2 per core, and a much larger 33 MB of shared L3. The larger Intel L3 cache likely helps with the data compression and multi-threaded workloads where it leads.

Memory support differs as well. AMD supports only DDR5, while Intel supports both DDR4 and DDR5. Both use dual-channel memory buses with identical peak bandwidth of 89.6 GB/s. Both support ECC memory. PCIe connectivity is another split: AMD offers Gen 4 with 20 lanes, Intel offers Gen 5 with 16 lanes.

Integrated graphics also differ. AMD pairs the CPU with Radeon 760M, while Intel uses UHD Graphics 730. The database records no performance comparison between these iGPU units. Socket compatibility is entirely separate: AMD uses Socket FP7, Intel uses Socket 1700. The Intel part carries a launch MSRP of $384; no launch MSRP is recorded for the AMD chip.

Where Each One Wins

The Intel Core 7 253PTE is the stronger processor for multi-threaded productivity. Its 41.6% lead in integer math and 36% lead in floating point math indicate substantial advantages in scientific computing, financial modeling, and rendering tasks that use wide instruction sets. The 20.9% physics win points to simulation workloads. The 14.9% Cinebench margins across all versions confirm consistent multi-core rendering superiority.

Intel also wins single-thread performance everywhere. The 14.9% Cinebench single-core margins and 6.1% PassMark single-thread margin mean everyday responsive tasks, such as application launches and light scripting, should feel faster on the Intel chip. The higher boost clock of 5.40 GHz directly supports this.

The AMD Ryzen 5 PRO 8640HS wins in extended instructions by 8.2% and random string sorting by 7.1%. Extended instructions covers workloads like cryptography, compression algorithms, and specialized math operations. Random string sorting reflects how quickly a processor can reorder data structures, which matters for database operations, text processing, and certain analytics pipelines. These are not niche tests; they represent real server and workstation tasks.

AMD's lower 28-watt TDP also positions it for thin-and-light mobile systems where thermal headroom is limited. The Intel part's 45-watt TDP suits desktop systems with active cooling. The database does not record power draw under load, so direct efficiency comparisons are not possible.

The Verdict

The data points to the Intel Core 7 253PTE for anyone who needs maximum throughput in multi-threaded or single-threaded workloads. It wins 15 of 17 head-to-head tests, with margins reaching 41.6% in integer math and 36% in floating point math. Its 84th percentile ranking among all CPUs versus AMD's 80th percentile reinforces its overall standing. The average benchmark score of 34,962 for Intel versus 28,478 for AMD represents a 22.8% gap.

The AMD Ryzen 5 PRO 8640HS should be chosen when the specific workloads are extended instructions or random string sorting, where it beats Intel by 8.2% and 7.1% respectively. It also suits systems where the 28-watt power envelope is a hard constraint, since it delivers respectable performance in a mobile form factor. Its nearest rivals in the database, the Intel Xeon E-2436 and AMD Ryzen 7 PRO 6850HS, sit within 0.2% of its average score, showing it is competitive within its class.

For general-purpose desktop computing, rendering, or heavy math, the Intel part is the data-driven pick. For mobile deployment or specialized string and instruction workloads, AMD holds the edge.
