Where Each One Wins

The Intel Core i5-13500 is the clear winner in multi-threaded workloads that scale across many cores. Its 14 cores and 20 threads dominate in Cinebench R15 and R20 multi-core tests, with leads of 20.9% and 32.6% respectively. The PassMark suite shows Intel winning every computational category, with particularly massive margins in floating point math (76.3% ahead), integer math (48.9% ahead), and data compression (47.2% ahead). The Intel chip also wins in encryption, extended instructions, prime number finding, physics, random string sorting, and the multithread test.

The AMD Ryzen 5 PRO 8645HS wins the modern single-core race and the latest Cinebench version. In Cinebench R23 single-core, AMD leads by 36.1%, and in R23 multi-core, AMD is ahead by 26.2% despite having only 6 cores. The AMD chip also wins Cinebench R15 single-core by 8.6%. For users running current-generation rendering software that uses Cinebench R23 as a proxy, the AMD processor delivers better results despite its lower core count.

The single-thread PassMark test is essentially a tie. Intel scores 3,865, AMD scores 3,858, a delta of just 0.2%. This indicates the two chips have nearly identical per-thread performance in that specific workload, even though Cinebench single-core tests tell a different story.

Architecture Differences

The Intel Core i5-13500 uses the Raptor Lake architecture, specifically Raptor Lake-S, built on Intel's 10 nm process. It is a desktop processor on Intel Socket 1700. The chip integrates UHD Graphics 770. Its cache layout features 80 KB L1 per core, 1.25 MB L2 per core, and 24 MB shared L3 cache. The die measures 215 mm².

The AMD Ryzen 5 PRO 8645HS uses the Zen 4 architecture under the Hawk Point codename, built on TSMC's 4 nm process. It is a mobile processor on AMD Socket FP7. The integrated GPU is Radeon 760M. Cache sizes are smaller: 64 KB L1 per core, 1 MB L2 per core, and 16 MB shared L3. The die measures 178 mm² and contains 25,000 million transistors.

The process node difference is significant. TSMC's 4 nm node is much newer and denser than Intel's 10 nm node. This allows AMD to pack 25 billion transistors into a smaller die while drawing less power. The Intel chip has a 65 W TDP, while the AMD chip has a 45 W TDP. Both are locked multipliers, so neither offers overclocking.

PCIe support differs as well. Intel provides Gen 5 with 16 lanes from the CPU. AMD provides Gen 4 with 20 lanes from the CPU. Intel's PCIe generation is newer, but AMD offers more lanes. Memory support also differs: Intel accepts both DDR4 and DDR5, AMD accepts only DDR5. AMD lists a memory bandwidth of 89.6 GB/s, while Intel does not specify a bandwidth figure in the database.

Head-to-Head Benchmarks

The biggest Intel win appears in PassMark floating point math. The Intel Core i5-13500 scores 80,198 versus AMD's 45,481, a 76.3% advantage. This is a decisive margin that shows Intel's core count advantage is leveraged heavily in floating-point-heavy workloads. Similarly, integer math shows Intel at 108,320 against AMD's 72,740, a 48.9% lead. Data compression follows at 47.2% ahead (391,249 versus 265,826), and data encryption is 28.4% ahead (22,333 versus 17,387).

In Cinebench R20 multi-core, Intel scores 10,990 versus AMD's 8,291, a 32.6% lead. The same 32.6% delta appears in Cinebench R20 single-core, where Intel scores 1,551 and AMD scores 1,170. This is a surprising result: AMD wins the R23 single-core test by a large margin but loses R20 single-core by the same percentage the other way. Cinebench R15 multi-core shows Intel ahead 20.9% (2,405 versus 1,989).

PassMark multithread gives Intel 31,285 versus AMD's 23,569, a 32.7% lead. Physics shows Intel at 1,645 versus 1,208, a 36.2% lead. Prime number finding is 39.7% ahead (102 versus 73). Random string sorting is 20.5% ahead (42,759 versus 35,472). Extended instructions are 12.9% ahead (23,956 versus 21,212).

The AMD wins are concentrated in Cinebench R23. In R23 multi-core, AMD scores 19,742 versus Intel's 14,573, a 26.2% lead. This is notable because AMD's 6-core, 12-thread chip outruns Intel's 14-core, 20-thread chip in this specific render test. In R23 single-core, AMD scores 2,787 versus 1,780, a 36.1% lead. Cinebench R15 single-core also goes to AMD at 280 versus 256, an 8.6% lead.

The two PassMark single-thread tests are essentially tied. Intel scores 3,865 in both, AMD scores 3,858 in both, with a 0.2% delta favoring Intel. This near-tie stands in contrast to the Cinebench single-core results, which vary widely between versions.

The Verdict

The data points to two very different processors for two very different use cases. The Intel Core i5-13500 is the multi-threaded workhorse. It wins 14 of 17 benchmarks, and its victories are often by large margins. The 76.3% lead in floating point math, 48.9% in integer math, and 47.2% in data compression make it the clear choice for computation-heavy tasks, database work, encryption workloads, and general productivity that scales across many threads. Its Cinebench R20 results, both multi-core and single-core, are 32.6% ahead of AMD. The Intel chip also supports both DDR4 and DDR5 memory, giving platform flexibility, and its PCIe Gen 5 interface is newer than AMD's Gen 4.

The AMD Ryzen 5 PRO 8645HS is the modern efficiency pick. It wins the Cinebench R23 tests decisively: 36.1% ahead in single-core and 26.2% ahead in multi-core. This suggests AMD's Zen 4 architecture, on a 4 nm node, is more efficient per core and better optimized for current rendering engines. The AMD chip also has a much lower TDP at 45 W versus 65 W, making it suitable for thinner laptops and mobile workstations. Its base clock of 4.30 GHz is far higher than Intel's 2.50 GHz, and its boost clock reaches 5.00 GHz. The AMD chip supports DDR5 only but lists a memory bandwidth of 89.6 GB/s.

For users running legacy multi-threaded workloads, Cinebench R15 and R20, and PassMark test suites, the Intel Core i5-13500 is the stronger performer. For users running modern Cinebench R23 workloads, especially single-thread-bound tasks, the AMD Ryzen 5 PRO 8645HS delivers better results with lower power consumption. The near-identical PassMark single-thread scores (0.2% delta) indicate that for many everyday tasks, the two chips are indistinguishable. The AMD chip's release date is over a year later, and its mobile segment designation suggests it targets laptops, while Intel targets desktops. The choice ultimately comes down to workload: Intel for core-heavy multitasking, AMD for modern rendering efficiency.
