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

AMD Ryzen 5 PRO 8645HS and Intel Core 7 253PTE occupy different positions in the processor landscape, with the recorded data showing a clear split between heavy multi-threaded workloads and specialized instruction sets. The Intel part wins 12 of the 17 head-to-head benchmark comparisons, while the AMD part takes 5. The overall average benchmark scores place the Intel part at 34962 against 30879 for the AMD part, a gap that reflects their differing core counts and platform designs. The following analysis breaks down where each processor demonstrates superiority based strictly on the measured results.

Where Each One Wins

The Intel Core 7 253PTE dominates in raw compute throughput across nearly all standard productivity and rendering workloads. Its wins include every Cinebench iteration, from R15 multicore at 2144 versus 1989, up through R23 multicore at 21276 versus 19742. The pattern extends into PassMark integer math, floating point math, prime number finding, physics, multithread, and data compression. The largest Intel advantages appear in floating point math (67209 versus 45481, a 32.3% delta) and integer math (119552 versus 72740, a 39.2% delta). These metrics indicate a processor built for sustained parallel computation, likely benefiting from its 10 cores and 20 threads.

The AMD Ryzen 5 PRO 8645HS wins in areas that rely on specific instruction efficiency rather than sheer core count. Its victories include passmark data encryption (17387 versus 15500, a 12.2% delta), extended instructions (21212 versus 17099, a 24.1% delta), and random string sorting (35472 versus 28227, a 25.7% delta). It also edges out the Intel part in single-thread performance, with 3858 versus 3794, a 1.7% delta. These results suggest the AMD architecture handles certain cryptographic, sorting, and single-threaded tasks more efficiently, even with fewer cores.

The use-case split is therefore straightforward: the Intel part for heavily threaded compute, compilation, rendering, and math-heavy workloads; the AMD part for security tasks, string manipulation, and lightly threaded applications where single-core speed matters.

Architecture Differences

The two processors diverge significantly in their fundamental designs. The AMD Ryzen 5 PRO 8645HS uses the Zen 4 architecture on a 4 nm TSMC process, with a 178 mm² die size and 25,000 million transistors. It features 6 cores and 12 threads, with a base clock of 4.30 GHz and a boost clock of 5.00 GHz. The cache hierarchy includes 64 KB L1 per core, 1 MB L2 per core, and 16 MB shared L3. Memory support is DDR5 only, dual-channel, with 89.6 GB/s bandwidth and ECC support enabled. PCIe connectivity is Gen 4 with 20 lanes from the CPU. The integrated graphics are Radeon 760M, and the socket is AMD FP7.

The Intel Core 7 253PTE uses the Bartlett Lake codename on a 10 nm Intel process, with 10 cores and 20 threads. Base clock is 1.80 GHz, boost clock is 5.40 GHz, and TDP is 45 W matching the AMD part. Cache sizes are larger: 80 KB L1 per core, 2 MB L2 per core, and 33 MB shared L3. Memory support includes both DDR4 and DDR5, dual-channel, with the same 89.6 GB/s bandwidth and ECC support. PCIe is Gen 5 with 16 lanes, a newer generation but fewer lanes. Integrated graphics are UHD Graphics 730. The socket is Intel 1700, and the market segment is desktop, whereas the AMD part is mobile.

The process node difference (4 nm versus 10 nm) explains some efficiency gaps, but the Intel part compensates with higher boost clock and nearly double the cores. The AMD part’s higher base clock (4.30 GHz versus 1.80 GHz) indicates a design optimized for immediate responsiveness, while the Intel part relies on boosting to reach its peak.

Head-to-Head Benchmarks

The Cinebench results show a consistent pattern: Intel wins every multicore and singlecore test by approximately 7.2% to 7.3%. For R15 multicore, Intel scores 2144 versus 1989. R15 singlecore is 302 versus 280. R20 multicore is 8935 versus 8291, and R20 singlecore is 1261 versus 1170. R23 multicore is 21276 versus 19742, and R23 singlecore is 3003 versus 2787. These margins are uniform, indicating a stable performance advantage across different Cinebench versions.

The PassMark suite reveals more varied results. Intel wins data compression (275828 versus 265826, a 3.6% delta), find prime numbers (82 versus 73, an 11% delta), floating point math (67209 versus 45481, a 32.3% delta), integer math (119552 versus 72740, a 39.2% delta), multithread (25031 versus 23569, a 5.8% delta), and physics (1318 versus 1208, an 8.3% delta). The AMD part wins data encryption (17387 versus 15500, a 12.2% delta), extended instructions (21212 versus 17099, a 24.1% delta), random string sorting (35472 versus 28227, a 25.7% delta), and both single-thread entries (3858 versus 3794, a 1.7% delta).

The largest Intel wins are in integer and floating point math, where the core count advantage is decisive. The largest AMD wins are in extended instructions and random string sorting, suggesting architectural optimizations for specific SIMD and memory access patterns. The single-thread win for AMD is narrow but consistent across both recorded entries.
