AMD Ryzen 5 PRO 7645 vs Intel Core i5-14600T Comparison

The Intel Core i5-14600T and AMD Ryzen 5 PRO 7645 both land in the 83rd percentile of all CPUs, but their benchmark profiles diverge sharply. The Intel part secures 14 of 17 head-to-head wins, driven by its larger core count and higher memory bandwidth, while the AMD part counters with decisive victories in extended instruction throughput and prime number computation. The data shows a clear split: Intel dominates general-purpose and floating-point workloads, while AMD holds a narrow but real edge in specialized integer and string-manipulation tasks.

Head-to-Head Benchmarks

The Intel Core i5-14600T wins every Cinebench iteration across both single-core and multi-core tests. In Cinebench R23 multi-core, the Intel part scores 22447 against AMD’s 21710, a 3.4% advantage. That margin repeats in Cinebench R20 multi-core (9427 vs 9118) and Cinebench R15 multi-core (2262 vs 2188), both at 3.4%. Single-core results follow the same pattern: Cinebench R23 single-core shows 3169 vs 3065 (3.4% ahead), and Cinebench R15 single-core shows 319 vs 308 (3.6% ahead). The Intel advantage is consistent but modest in rendering workloads.

PassMark’s math tests reveal the largest gaps. In floating-point math, the Intel part scores 64726 against AMD’s 45202 — a staggering 43.2% lead. Integer math also favors Intel heavily: 95112 vs 74782, a 27.2% margin. Physics simulation shows a 17.2% Intel advantage (1873 vs 1598). These results indicate that the Intel chip’s 14 cores and 20 threads translate directly into raw compute throughput that the 6-core, 12-thread AMD part cannot match.

However, the AMD Ryzen 5 PRO 7645 posts a massive win in extended instructions (PassMark), scoring 21813 against Intel’s 16985 — a 22.1% deficit for Intel. Prime number finding also favors AMD dramatically: 198 vs 121, meaning AMD completes this workload 38.9% better. Random string sorting goes to AMD by a slim 0.7% (34557 vs 34310). These three wins suggest AMD’s Zen 4 architecture handles specific instruction patterns and memory access sequences more efficiently, even with fewer cores.

The remaining wins for Intel are smaller but numerous. Data encryption shows a 9.4% Intel lead (18226 vs 16657), and data compression is 5.4% ahead (301827 vs 286298). PassMark multi-thread scores Intel 3.6% higher (26409 vs 25489), and single-thread scores Intel 2.5% higher (3744 vs 3652). The average benchmark score tells the same story: Intel at 32707 versus AMD at 32446, a 0.8% overall gap. The Intel part’s nearest rivals include the Intel Core Ultra 7 155H (0% delta) and AMD Ryzen 5 7400F (-0.1%), while AMD’s nearest rivals include the AMD Ryzen 7 6800HS (0.3% ahead) and Intel Core i5-14400F (0.5% ahead).

The Verdict

From the data, the Intel Core i5-14600T is the better choice for users prioritizing multi-threaded compute, floating-point math, and encryption/compression workloads. Its 14-core configuration delivers a 43.2% lead in floating-point math and a 27.2% lead in integer math over the AMD part. The Intel chip also wins every Cinebench test, making it the default pick for rendering and CPU-bound creative tasks. With a launch MSRP of $255, it offers a strong baseline for desktop builds, though the AMD part has no listed launch MSRP to compare.

The AMD Ryzen 5 PRO 7645 is the better choice for users running extended instruction sets or prime number algorithms. Its 22.1% lead in extended instructions and 38.9% lead in prime finding indicate superior per-core efficiency for these specific workloads. The AMD part also targets the server/workstation segment, suggesting it is built for sustained, niche compute tasks rather than general desktop use. However, its 65W TDP versus Intel’s 35W TDP means higher power draw for fewer cores, and it loses in data compression, encryption, and all Cinebench tests.

Choose Intel for balanced performance across a wide range of tasks. Choose AMD only if your workload is dominated by the specific PassMark tests it wins. The data does not support AMD for general-purpose computing; its wins are too narrow and too specialized to offset Intel’s broad dominance.

Architecture Differences

The Intel Core i5-14600T is built on a 10 nm process at Intel’s foundry, using the Raptor Lake architecture (codename Raptor Lake-R, Core 14th Gen).

Where Each One Wins

Intel wins in all rendering and multi-threaded workloads. The Cinebench R15, R20, and R23 suites show a consistent 3.3% to 3.6% lead in both single-core and multi-core tests. PassMark physics (17.2% ahead), floating-point math (43.2% ahead), and integer math (27.2% ahead) further cement Intel’s dominance in compute-heavy tasks. Data encryption (9.4% ahead) and data compression (5.4% ahead) make Intel the stronger choice for archive handling and security-related processes. PassMark multi-thread (3.6% ahead) and single-thread (2.5% ahead) reinforce Intel’s overall superiority. The Intel part also has a lower TDP (35W vs 65W), meaning it achieves these results with lower power draw.

AMD wins in three specific PassMark tests. Extended instructions show a 22.1% lead, indicating better execution of advanced instruction sets like AVX-512 or similar. Prime number finding shows a 38.9% lead, which points to superior integer division and modular arithmetic performance. Random string sorting shows a 0.7% lead, a marginal win in memory-access-heavy string operations. These wins suggest AMD’s Zen 4 architecture is more efficient per core for certain algorithmic patterns. However, the AMD part has more PCIe lanes (24 vs 16) and a higher memory bandwidth (83.2 GB/s vs no listed bandwidth for Intel), which could benefit workloads that are memory-lane or bandwidth constrained.
