AMD Ryzen 7 PRO 7745 vs Intel Core i5-13600 Comparison

The Intel Core i5-13600 and AMD Ryzen 7 PRO 7745 are both 65 W desktop processors that land in the 88th percentile of all CPUs, but they achieve that standing through very different designs. The Intel part uses 14 cores (6 performance and 8 efficiency) with 20 threads, while the AMD chip uses 8 full-size Zen 4 cores with 16 threads. Benchmark results show a clear split: AMD wins 12 of 17 head-to-head tests, including every Cinebench iteration, while Intel takes 5 wins, mostly in math-heavy PassMark workloads. The data suggests the Ryzen 7 PRO 7745 is the better all-rounder for threaded productivity, but the Core i5-13600 is the pick when floating-point or integer math dominates the workload. Neither chip has an unlocked multiplier, so overclocking is off the table for both.

The Verdict

The data points to the AMD Ryzen 7 PRO 7745 as the stronger processor for general multi-threaded work. It wins all six Cinebench tests, from R15 multi-core (2809 vs 2683) to R23 multi-core (27877 vs 26620), with a consistent 4.5% margin across every Cinebench iteration. It also wins PassMark multithread (32733 vs 31725) and data compression (386829 vs 383972). If your workload is rendering, encoding, or any task that scales with Cinebench-style threading, the Ryzen part is the safer choice.

The Intel Core i5-13600 is the better pick for specific math-heavy tasks. It wins floating-point math by a massive 29.3% (81892 vs 63332) and integer math by 7.5% (111044 vs 103330). It also wins PassMark single-thread (4049 vs 3849, a 5.2% edge) and physics (1782 vs 1699, a 4.9% edge). If your software is dominated by raw arithmetic or lightly-threaded single-core performance, the Intel chip is the one to buy.

For everyone else, the Ryzen 7 PRO 7745 is the default recommendation. It wins 12 of 17 tests, including the biggest Cinebench margins and a 21.1% lead in extended instructions (29216 vs 23045). The AMD part also has the higher boost clock (5.30 GHz vs 5.00 GHz) and a larger L3 cache (32 MB vs 24 MB), which explains its edge in most tests. The Intel chip is not a bad processor, but its strengths are narrower and more specialized.

Q: What is the memory bandwidth difference?

A: The AMD Ryzen 7 PRO 7745 lists a memory bandwidth of 83.2 GB/s, while the Intel Core i5-13600 does not have a bandwidth figure in the data. Both support dual-channel memory, but Intel supports DDR4 and DDR5, while AMD supports only DDR5.

Architecture Differences

The two chips come from fundamentally different design philosophies. Intel’s Core i5-13600 uses Raptor Lake architecture on a 10 nm process from Intel’s own foundry, with a die size of 215 mm². It uses a hybrid layout with 14 cores total: performance cores and efficiency cores, which explains the 20 threads from 14 cores. The AMD Ryzen 7 PRO 7745 uses Zen 4 architecture on a 5 nm process from TSMC, with a much smaller 71 mm² die and 6,570 million transistors. AMD’s chip uses 8 full-size cores with 16 threads, no hybrid approach.

Cache layouts also differ significantly. Intel allocates 80 KB of L1 per core, 1.25 MB of L2 per core, and 24 MB of shared L3. AMD gives each core 64 KB of L1, 1 MB of L2, and a larger 32 MB shared L3. The larger L3 cache on the AMD part likely contributes to its wins in data compression and random string sorting, where cache capacity matters more. Neither chip has 3D V-Cache.

The integrated graphics differ too. Intel includes UHD Graphics 770, while AMD includes Radeon Graphics. Both are listed as desktop processors, but AMD’s market segment is labeled as Server/Workstation, while Intel’s is Desktop. This is a notable distinction even though both are active production parts. The AMD chip’s socket is AM5, while Intel uses Socket 1700, meaning platform choices are entirely separate.

Specification Differences

The most obvious difference is core count: Intel has 14 cores and 20 threads, AMD has 8 cores and 16 threads. Clock speeds favor AMD, with a base clock of 3.80 GHz and boost clock of 5.30 GHz, versus Intel’s 2.70 GHz base and 5.00 GHz boost. Both have a 65 W TDP.

Process node and foundry differ: Intel uses 10 nm at Intel, AMD uses 5 nm at TSMC. Die size is dramatically different (215 mm² vs 71 mm²), and AMD lists 6,570 million transistors while Intel does not list a transistor count. Cache differs in all levels: Intel has 80 KB L1 per core, 1.25 MB L2 per core, and 24 MB L3; AMD has 64 KB L1, 1 MB L2, and 32 MB L3.

Memory support is a key differentiator. Intel supports both DDR4 and DDR5, while AMD only supports DDR5. Both are dual-channel, but AMD lists a memory bandwidth of 83.2 GB/s; Intel has no bandwidth figure. Both support ECC memory. PCIe lanes differ: Intel has Gen 5 with 16 lanes (CPU only), AMD has Gen 5 with 24 lanes (CPU only).

Integrated graphics are different: Intel’s UHD Graphics 770 versus AMD’s Radeon Graphics. Release dates are also different: Intel launched on 2023-01-03, AMD on 2023-06-12. Intel has a launch MSRP of $255; AMD has no launch MSRP listed. Both are locked (multiplier not unlocked). The part numbers are SRMBS for Intel and 100-000000599 for AMD.

Head-to-Head Benchmarks

The AMD Ryzen 7 PRO 7745 dominates the Cinebench suite. In R15 multi-core, it scores 2809 versus Intel’s 2683, a 4.5% lead. The same margin appears in R15 single-core (396 vs 378), R20 multi-core (11708 vs 11180), R20 single-core (1652 vs 1578), R23 multi-core (27877 vs 26620), and R23 single-core (3935 vs 3758). This consistency suggests AMD’s architecture is uniformly better at Cinebench-style rendering workloads, regardless of thread count or single-core performance.

In PassMark tests, the picture is more mixed. AMD wins data compression (386829 vs 383972, only 0.7% ahead), data encryption (22821 vs 22182, 2.8% ahead), extended instructions (29216 vs 23045, a massive 21.1% lead), find prime numbers (166 vs 109, a 34.3% lead), multithread (32733 vs 31725, 3.1% ahead), and random string sorting (46759 vs 42040, 10.1% ahead). These wins are substantial in several cases, especially extended instructions and prime numbers.

Intel’s wins are fewer but sharp. Floating-point math is the standout: Intel scores 81892 versus AMD’s 63332, a 29.3% advantage. Integer math goes Intel’s way by 7.5% (111044 vs 103330). Single-thread performance also favors Intel in PassMark (4049 vs 3849, 5.2% ahead), and physics is close but Intel wins (1782 vs 1699, 4.9% ahead). The overall tally is 12 wins for AMD and 5 for Intel.

Where Each One Wins

The AMD Ryzen 7 PRO 7745 wins in rendering and threaded productivity. Every Cinebench test goes to AMD, making it the clear choice for 3D rendering, video encoding, or any workload that mirrors those benchmarks. It also wins PassMark multithread, so heavily threaded general computing favors AMD. The 21.1% lead in extended instructions and 34.3% lead in find prime numbers suggest AMD is better at encryption, scientific computing, and workloads using specialized instruction sets. Data compression and random string sorting wins point to database or file-compression tasks.

The Intel Core i5-13600 wins in math-heavy floating-point and integer workloads. The 29.3% floating-point margin is the single largest win in either direction, so any software relying on FPU math — simulation, certain financial models, or physics calculations — should favor Intel. Integer math also goes to Intel by 7.5%. The PassMark single-thread win (5.2%) means Intel is slightly better for legacy single-threaded applications that use PassMark’s specific test methodology. The physics win (4.9%) is narrow but consistent with Intel’s math strengths.

For a general user, the AMD chip is the safer bet because it wins more tests and by larger margins in the most common productivity benchmarks. For a specialized user running math-heavy code, Intel’s wins in floating-point and integer math outweigh its losses elsewhere. The choice comes down to workload: multi-threaded general purpose favors AMD, raw arithmetic favors Intel.
