AMD Ryzen 5 3600XT vs Intel Core i7-1365U Comparison

The Intel Core i7-1365U and AMD Ryzen 5 3600XT are fundamentally different processors aimed at different use cases, and the benchmark data reflects that split clearly. The Ryzen 5 3600XT, a desktop part with a 95 W TDP, dominates multi-threaded and sustained workloads, winning 13 of the 17 head-to-head comparisons. The Core i7-1365U, a 15 W mobile chip, wins only 4, but those wins are in single-threaded and floating-point tasks where its high boost clock and efficiency-focused architecture shine. The data shows a classic trade-off: raw throughput versus per-core responsiveness and power efficiency.

Where Each One Wins

The AMD Ryzen 5 3600XT is the clear winner for productivity and heavy multi-threaded work. It leads by double-digit margins in Cinebench R15, R20, and R23 multi-core tests, with the R23 gap reaching 43.3%. It also crushes the Intel part in memory-sensitive and integer-heavy workloads: data compression is 35.1% faster, data encryption 34.8% faster, and random string sorting 32% faster. The Ryzen part also wins in PassMark's multithread test by 24.3% and in physics by 20.2%. If you are rendering, compiling, compressing files, or running any workload that scales across cores, the Ryzen 5 3600XT is the obvious choice based on the recorded data.

The Intel Core i7-1365U wins where single-thread speed and floating-point math matter more. It beats the Ryzen part by 18.5% in Cinebench R15 single-core, and by 23.9% in PassMark single-thread. It also wins floating-point math by 11.7%. These results suggest the Intel chip is better suited for lightly threaded applications, responsive day-to-day use, and workloads that rely on FPU throughput, such as certain scientific calculations or media processing that is not fully multi-threaded. The Intel part also has integrated Iris Xe Graphics, which the Ryzen part lacks, making it a more complete package for a system without a discrete GPU.

Head-to-Head Benchmarks

The largest win for the AMD Ryzen 5 3600XT is in Cinebench R23 multi-core, where it scores 15776 versus 8946 for the Intel part, a 43.3% margin. This is a massive gap and indicates that for sustained all-core rendering, the Ryzen part is in a different class. The Ryzen part also wins Cinebench R20 multi-core by 26.3% (6625 versus 4882) and Cinebench R15 multi-core by 7.8% (1590 versus 1466.5). The margin shrinks as the workload gets shorter, which suggests the Intel part's boost behavior helps in shorter bursts.

In PassMark, the Ryzen part wins data compression by 35.1% (230645 versus 149585), data encryption by 34.8% (14608 versus 9531), extended instructions by 42.9% (14585 versus 8321), find prime numbers by 48.7% (113 versus 58), multithread by 24.3% (18562 versus 14045), physics by 20.2% (1210 versus 966), random string sorting by 32% (24960 versus 16977), and integer math by just 1% (51416 versus 50881).

The Intel Core i7-1365U's wins are more concentrated. Its biggest victory is in PassMark single-thread, where it scores 3411 versus 2752, a 23.9% advantage. It also wins Cinebench R15 single-core by 18.5% (265.5 versus 224) and floating-point math by 11.7% (33689 versus 30149). Notably, the Intel part loses the Cinebench R20 single-core test by 26.3% (689 versus 935) and R23 single-core by 15.3% (1887 versus 2227), which complicates the single-thread picture. In the newer Cinebench versions, the Ryzen part's higher base clock and IPC advantage show through even in single-threaded tests.

The overall average benchmark score tells a similar story: the Intel part sits at 18177 with a 72nd percentile ranking, while the AMD part sits at 17891 with a 71st percentile ranking. These are nearly identical, but the distribution of wins is heavily skewed toward the Ryzen part in multi-threaded tests.

Specification Differences

The two processors differ in nearly every core specification. The Intel Core i7-1365U has 10 cores and 12 threads, while the AMD Ryzen 5 3600XT has 6 cores and 12 threads. The Intel part has a base clock of 1.80 GHz and a boost clock of 5.20 GHz, while the AMD part has a base clock of 3.80 GHz and a boost clock of 4.50 GHz. The higher boost clock on the Intel part explains its single-thread wins in some benchmarks, while the AMD part's higher base clock helps it sustain multi-threaded performance.

TDP is a major differentiator: 15 W for the Intel part versus 95 W for the AMD part. The Intel part uses the Intel BGA 1744 socket, while the AMD part uses AMD Socket AM4. The Intel part is built on Intel's 10 nm process, while the AMD part is built on TSMC's 7 nm process. The AMD part has 3,800 million transistors on a 74 mm² die; the Intel part's transistor count and die size are not listed in the database.

Memory support also differs: the Intel part supports DDR4 and DDR5, while the AMD part supports DDR4 only. The AMD part lists a memory bandwidth of 51.2 GB/s, while the Intel part's bandwidth is not specified. Both use dual-channel memory. PCIe support differs as well: the Intel part has Gen 4 with 8 lanes (CPU only), while the AMD part has Gen 4 with no lane count specified.

The AMD Ryzen 5 3600XT has an unlocked multiplier, making it overclockable, while the Intel Core i7-1365U does not. The Intel part includes Iris Xe Graphics 96EU; the AMD part has no integrated graphics. The AMD part is a desktop processor, while the Intel part is a mobile processor.

Architecture Differences

The Intel Core i7-1365U is built on Raptor Lake architecture, specifically Raptor Lake-U, and uses Intel's 10 nm process. Its cache hierarchy is configured as 80 KB of L1 per core, 1.25 MB of L2 per core, and 12 MB of shared L3 cache. The AMD Ryzen 5 3600XT is built on Zen 2 architecture, codenamed Matisse 2, and uses TSMC's 7 nm process. Its cache is configured as 64 KB of L1 per core, 512 KB of L2 per core, and 32 MB of shared L3 cache. The AMD part has significantly more L3 cache (32 MB versus 12 MB), which helps in workloads that benefit from larger on-die data storage.

The Intel part uses a hybrid architecture typical of Raptor Lake-U, which combines performance and efficiency cores to balance power draw and throughput, though the database does not break down the core types. The AMD part uses a homogeneous set of six Zen 2 cores, all clocked equally, which simplifies scheduling and allows all cores to contribute equally to multi-threaded loads.

The foundry difference is also notable: Intel fabricates its own chip on a 10 nm node, while AMD uses TSMC's 7 nm node. The smaller process node on the AMD part contributes to its higher transistor density and efficiency despite the higher TDP. The AMD part's unlocked multiplier and desktop socket make it a more flexible platform for enthusiasts, while the Intel part's integrated graphics and mobile socket target thin-and-light laptops.

The Verdict

The data points to a clear conclusion for different buyers. The AMD Ryzen 5 3600XT is the choice for anyone running sustained multi-threaded workloads: rendering, video encoding, data compression, encryption, or physics simulations. It wins 13 of 17 head-to-head benchmarks, often by 30% or more, and its 32 MB of L3 cache and higher base clock give it a decisive advantage in throughput-heavy tasks. Its unlocked multiplier also allows for overclocking, which is not possible on the Intel part.

The Intel Core i7-1365U is the choice for mobile users who need strong single-thread responsiveness and do not want to sacrifice the ability to run without a discrete GPU. It wins PassMark single-thread by 23.9% and floating-point math by 11.7%, and its integrated Iris Xe Graphics 96EU means it can handle display output and basic graphics workloads on its own. Its 15 W TDP makes it suitable for ultraportable laptops, whereas the Ryzen part's 95 W TDP requires a desktop platform with adequate cooling.

There is no overall winner here, only the right tool for the job. The Ryzen 5 3600XT is a desktop workhorse that dominates multi-threaded benchmarks, while the Core i7-1365U is a mobile efficiency part that wins in specific single-threaded and FPU-heavy tests. The nearly identical average benchmark scores (18177 versus 17891) and percentiles (72 versus 71) disguise how differently these two chips perform in practice. Buyers should match the processor to their workload: sustained all-core performance points to AMD, while bursty single-thread work and integrated graphics point to Intel.
