AMD Ryzen 5 PRO 8645HS vs Intel Core 7 360 Comparison

The AMD Ryzen 5 PRO 8645HS and Intel Core 7 360 are both mobile processors aimed at laptops, but they represent very different design philosophies. The AMD part is a high-power, multi-threaded workhorse, while the Intel part is a low-power, single-thread specialist. The recorded data shows a clear split: the AMD wins 13 of the 17 head-to-head benchmarks, while the Intel wins 4. This breakdown is not just about speed, it is about what each chip is built to do.

Where Each One Wins

The AMD Ryzen 5 PRO 8645HS dominates almost every multi-threaded and throughput-oriented workload. Its wins in Cinebench R23 multi-core (19742 vs 13634, a 44.8% lead) and PassMark multi-thread (23569 vs 15544, a 51.6% lead) show that its 12 threads provide a massive advantage over the Intel's 6 threads. This extends to data tasks: data compression (265826 vs 142877, 86.1% ahead), data encryption (17387 vs 11164, 55.7% ahead), and random string sorting (35472 vs 17636, 101.1% ahead) all heavily favor the AMD. The largest single win is in integer math, where the AMD scores 72740 against 34238, a 112.5% advantage. This is the chip for compiling code, rendering, archiving, and any task that can use many threads.

The Intel Core 7 360 wins in a narrower set of tests. Its most decisive victory is in PassMark find prime numbers (120 vs 73, a 39.2% lead for the Intel), which is a test that heavily rewards raw single-core frequency. It also wins PassMark single-thread (4274 vs 3858, a 9.7% lead) and the identical PassMark singlethread test. Its fourth win is in PassMark physics, but by a negligible margin (1213 vs 1208, just 0.4%). The Intel also wins floating point math by a very narrow 1.2% (44963 vs 45481 is actually an AMD win, so the Intel's only other win is the prime number test, physics, and the two single-thread tests). The Intel's wins are all in tests that are either single-threaded or do not scale well with cores, showing that its higher boost clock of 4.80 GHz can overcome the AMD's 5.00 GHz in some integer workloads.

Architecture Differences

The two chips are built on fundamentally different foundations. The AMD Ryzen 5 PRO 8645HS uses the Zen 4 architecture, codenamed Hawk Point, on a 4 nm TSMC process. It has 6 cores and 12 threads, with a base clock of 4.30 GHz and a boost clock of 5.00 GHz. Its TDP is 45 W. The Intel Core 7 360 uses the Wildcat Lake architecture, on a 3 nm Intel process. It also has 6 cores, but only 6 threads, with a base clock of 1.50 GHz and a boost clock of 4.80 GHz. Its TDP is 15 W, which is one-third of the AMD's power envelope.

The cache configurations differ significantly. The AMD has 64 KB of L1 cache per core, 1 MB of L2 per core, and 16 MB of shared L3 cache. The Intel has 192 KB of L1 per core, 2.5 MB of L2 per core, but only 6 MB of shared L3 cache. The AMD's larger L3 is a key reason for its multi-threaded throughput, but the Intel's larger L1 and L2 per core support its single-thread performance.

Memory support also splits the two. The AMD supports DDR5 on a dual-channel bus, yielding a memory bandwidth of 89.6 GB/s. The Intel supports both DDR5 and LPDDR5X, but on a single-channel bus, with a lower memory bandwidth of 59.7 GB/s. The AMD also supports ECC memory, while the Intel does not. The AMD has 20 PCIe Gen 4 lanes from the CPU, while the Intel has only 6. The integrated graphics differ as well: the AMD uses a Radeon 760M, while the Intel uses Xe3 Graphics with 2 Xe cores.

Head-to-Head Benchmarks

The Cinebench suite shows a consistent 44.8% to 45.1% advantage for the AMD across all versions and both single and multi-core tests. In Cinebench R15 multi-core, the AMD scores 1989 against 1374. In R15 single-core, it is 280 against 193. The R20 tests show 8291 vs 5726 multi-core and 1170 vs 808 single-core. The R23 tests show 19742 vs 13634 multi-core and 2787 vs 1924 single-core. This consistency indicates that the AMD's advantage is structural, not workload-specific.

The PassMark suite reveals the Intel's specific strengths. In find prime numbers, the Intel scores 120, while the AMD scores 73, a 39.2% win for the Intel. In PassMark single-thread, the Intel scores 4274 against 3858, a 9.7% lead. The physics test is nearly identical (1213 vs 1208, a 0.4% Intel win). The AMD wins the remaining PassMark tests by margins ranging from 1.2% in floating point math to 112.5% in integer math. The data compression test shows an 86.1% AMD lead, and the random string sorting test shows a 101.1% AMD lead.

FAQ

Q: Which processor has more threads and why does it matter?

A: The AMD Ryzen 5 PRO 8645HS has 12 threads, while the Intel Core 7 360 has 6 threads. The AMD's additional threads allow it to process more parallel workloads simultaneously, which is why it wins multi-threaded tests like Cinebench R23 multi-core by 44.8%.

Q: The Intel chip has a higher PassMark single-thread score. What does that mean?

A: The Intel Core 7 360 scores 4274 in PassMark single-thread, compared to 3858 for the AMD, a 9.7% lead. This indicates that for lightly-threaded tasks that depend on a single core, such as some legacy applications or certain logic puzzles, the Intel chip can respond faster.

Q: Is the Intel processor more efficient despite its lower performance?

A: The recorded data shows the Intel Core 7 360 has a TDP of 15 W, while the AMD Ryzen 5 PRO 8645HS has a TDP of 45 W. This is a threefold difference in power draw, suggesting the Intel chip is designed for lighter, fanless or passively cooled systems, while the AMD is designed for performance laptops with active cooling.

Q: Which processor has a larger cache?

A: The AMD Ryzen 5 PRO 8645HS has 16 MB of shared L3 cache and 1 MB of L2 per core. The Intel Core 7 360 has 6 MB of shared L3 cache and 2.5 MB of L2 per core. The AMD's larger L3 cache helps with shared data across cores, while the Intel's larger L2 helps with per-core data.

Q: What is the launch MSRP of the Intel processor?

A: The launch MSRP of the Intel Core 7 360 is $426.

Q: Which processor has a higher memory bandwidth?

A: The AMD Ryzen 5 PRO 8645HS has a memory bandwidth of 89.6 GB/s on a dual-channel DDR5 bus. The Intel Core 7 360 has a memory bandwidth of 59.7 GB/s on a single-channel bus, which is significantly lower.

The Verdict

The data indicates that the AMD Ryzen 5 PRO 8645HS is the stronger performer in the vast majority of benchmarks. It wins 13 of 17 head-to-head tests, with its largest leads coming in integer math (112.5%), random string sorting (101.1%), and data compression (86.1%). Its 12 threads and 45 W TDP make it the clear choice for multi-threaded professional workloads like video editing, 3D rendering, and software compilation. The AMD also has a higher average benchmark score of 30879, placing it in the 82nd percentile of all CPUs, while the Intel has an average of 18374, in the 72nd percentile.

The Intel Core 7 360 is a different class of product. Its 15 W TDP and single-channel memory bus position it for ultra-portable devices where battery life and cooling are more important than raw compute. Its wins in single-thread tests (4274 vs 3858) and prime number finding (120 vs 73) show it can handle basic responsiveness and legacy single-threaded code. However, its 6 threads and lower cache mean it is not suitable for heavy parallel work. The benchmark data suggests that the AMD is for users who need performance, while the Intel is for users who need a low-power chip for light tasks. The Intel's launch MSRP is $426, but its performance profile is more comparable to the Intel Core i3-13100, which has an average score of 18380, a 0% delta, confirming its position in the entry-level desktop segment despite its mobile socket.
