AMD Ryzen 7 5700X3D vs Intel Core i5-13400F Comparison

Where Each One Wins

The benchmark database splits these two desktop processors along fairly clear lines. The AMD Ryzen 7 5700X3D wins 9 of the 25 head-to-head tests, while the Intel Core i5-13400F takes the remaining 16. That raw count favors Intel, but the nature of those wins tells the real story.

The Ryzen 7 5700X3D dominates in workloads that stress the memory subsystem and cache hierarchy. Its biggest victory is in PassMark's find prime numbers test, where it scores 224 versus Intel's 83, a massive 169.9% advantage. Physics simulation also favors AMD heavily: 2686 versus 1437, an 86.9% lead. Data encryption shows a 13.1% edge (18788 vs 16608), and extended instructions land 6.8% ahead (21202 vs 19847). These are classic cache-sensitive, latency-sensitive tasks where the 3D V-Cache design pays off.

The Intel Core i5-13400F counters in throughput-heavy and floating-point workloads. Its most lopsided win is PassMark floating point math, scoring 60539 against AMD's 46492, a 23.2% margin. Single-thread performance also favors Intel decisively, with PassMark single thread at 3634 versus 2970 (18.3% ahead) and 3DMark single thread at 960 versus 804 (16.2% ahead). The 3DMark thread scaling tests all go Intel's way, with the 2-thread test showing a 16.2% gap and the 4-thread test at 10.5%.

For mixed real-world use, Cinebench results are close. R23 multicore goes to Intel by just 1.1% (22604 vs 22366), while R20 multicore goes to AMD by 5.6% (9393 vs 8892). Geekbench multicore is nearly a tie, with AMD ahead by only 0.2% (11086 vs 11068). The overall average benchmark scores reflect this: Intel sits at 25292, AMD at 24709, a gap of roughly 2.4%. Both CPUs hold the 77th percentile among all processors in the database.

Architecture Differences

The two chips come from fundamentally different design philosophies. The AMD Ryzen 7 5700X3D uses Zen 3 architecture on TSMC's 7 nm process, with the Vermeer codename. It packs 8 cores and 16 threads on an 74 mm² die containing 8,850 million transistors. The defining feature is the 96 MB shared L3 cache, which is what gives it that massive advantage in cache-sensitive workloads.

The Intel Core i5-13400F uses Raptor Lake architecture on Intel's 10 nm process, with a much larger 215 mm² die. It offers 10 cores and 16 threads, but those are not all equal: the configuration mixes performance and efficiency cores, which explains why it matches AMD's thread count despite having more physical cores. Its L3 cache is a comparatively modest 20 MB shared, though it makes up for that with a larger L2 allocation of 1.25 MB per core versus AMD's 512 KB per core.

Memory support differs in an important way. The AMD chip supports only DDR4 with dual-channel memory and a bandwidth of 51.2 GB/s. The Intel chip supports both DDR4 and DDR5, also dual-channel, though the database does not record a bandwidth figure for it. That memory flexibility is a practical consideration for anyone choosing a platform. AMD also supports ECC memory; Intel does not.

PCIe connectivity also differs. The AMD chip provides Gen 4 with 20 CPU lanes, while Intel provides Gen 5 with 16 CPU lanes. For most desktops, the extra generation on Intel's side is offset by fewer total lanes. Neither chip has an unlocked multiplier, so overclocking is not an official option on either. The AMD chip has no integrated graphics; the Intel F-series part also lacks integrated graphics by design, as the F suffix indicates.

Process node and foundry differences matter for efficiency and heat characteristics. The AMD chip lists a TDP of 105 watts, while Intel lists 65 watts. The Intel chip also runs a higher boost clock at 4.60 GHz versus 4.10 GHz on AMD, with a lower base clock at 2.50 GHz versus 3.00 GHz. The AMD part is manufactured by TSMC; the Intel part by Intel's own fabs.

Head-to-Head Benchmarks

Starting with the 3DMark suite, Intel wins every test. The 16-thread test shows 7314 versus 6764 (7.5% ahead), and the max-thread test is similar at 7307 versus 6755 (7.6% ahead). The gap widens at lower thread counts: 8-thread is 5591 versus 5357 (4.2%), 4-thread is 3459 versus 3097 (10.5%), and 2-thread is 1880 versus 1575 (16.2%). The single-thread test also goes to Intel at 960 versus 804 (16.2%). This pattern suggests Intel's higher boost clock and per-core efficiency give it a clear edge in lightly threaded and gaming-style synthetic loads.

Cinebench results are more split. R15 multicore goes to Intel by a hair: 2278 versus 2254, just 1.1%. R15 singlecore is even closer, 321 versus 318, a 0.9% gap. R20 flips to AMD, with multicore at 9393 versus 8892 (5.6% ahead) and singlecore at 1325 versus 1255 (5.6% ahead). R23 returns to Intel, with multicore at 22604 versus 22366 (1.1%) and singlecore at 3191 versus 3157 (1.1%). The alternating pattern indicates these chips trade blows depending on the specific Cinebench version and its workload characteristics.

Geekbench shows a near tie in multicore, with AMD at 11086 and Intel at 11068, a 0.2% margin. Singlecore goes to Intel decisively at 1996 versus 1849, a 7.4% gap. That single-thread deficit is the AMD chip's most consistent weakness across the entire benchmark suite.

PassMark tests reveal the architectural split most clearly. Intel wins data compression (311364 vs 307237, 1.3%), floating point math (60539 vs 46492, 23.2%), random string sorting (32076 vs 31492, 1.8%), and single thread (3634 vs 2970, 18.3%). AMD wins data encryption (18788 vs 16608, 13.1%), extended instructions (21202 vs 19847, 6.8%), find prime numbers (224 vs 83, 169.9%), integer math (81257 vs 79942, 1.6%), multithread (26318 vs 25032, 5.1%), and physics (2686 vs 1437, 86.9%). The prime number and physics results are outliers in magnitude, showing how extreme the cache advantage can become.

FAQ

Q: Which CPU is better for gaming?

A: The data points to the AMD Ryzen 7 5700X3D for cache-sensitive gaming scenarios. Its 96 MB L3 cache produces a 169.9% win in prime number finding and an 86.9% win in physics simulation, both of which correlate with game-like workloads. The Intel chip wins 3DMark thread tests, but those favor raw clock speed rather than cache behavior.

Q: Which CPU has better single-thread performance?

A: The Intel Core i5-13400F clearly wins every single-thread test. PassMark single thread shows 3634 versus 2970 (18.3% ahead), 3DMark single thread shows 960 versus 804 (16.2% ahead), and Geekbench singlecore shows 1996 versus 1849 (7.4% ahead). Intel's 4.60 GHz boost clock versus AMD's 4.10 GHz is the likely driver.

Q: Do these CPUs support the same memory types?

A: No. The AMD chip supports DDR4 only, with 51.2 GB/s bandwidth. The Intel chip supports both DDR4 and DDR5. Intel also lacks ECC memory support, which AMD includes. This makes the AMD platform more constrained for future memory upgrades but potentially more stable for error-sensitive workloads.

The AMD chip launched on 2024-01-07 with a launch MSRP of $249. The Intel chip launched on 2023-01-03 with a launch MSRP of $196. Both remain in active production.

The Verdict

If the workload is cache-sensitive, the AMD Ryzen 7 5700X3D is the clear pick. The data shows a 169.9% lead in prime number finding, an 86.9% lead in physics, a 13.1% lead in encryption, and a 6.8% lead in extended instructions. Those are not marginal differences; they reflect a fundamental architectural advantage in handling repeated data access. For simulation, scientific workloads, or any task that benefits from a massive L3 cache, the AMD chip is the one to choose.

If the workload is throughput-heavy or floating-point intensive, the Intel Core i5-13400F is the better option. It wins 16 of 25 head-to-head tests, including a 23.2% margin in floating point math and an 18.3% margin in single-thread performance. Its lower TDP of 65 watts versus 105 watts also makes it an easier fit for modest cooling setups. The higher boost clock of 4.60 GHz gives it a consistent edge in lightly threaded and bursty workloads.

The overall average scores put Intel ahead at 25292 versus 24709, but that aggregate hides the split personality of these chips. In Cinebench R23 multicore, the gap is only 1.1% in Intel's favor. In R20 multicore, AMD leads by 5.6%. These are not chips where one simply outperforms the other; they are tools for different jobs.

The practical recommendation from the database is straightforward. For a gaming-focused build where cache behavior dominates, the AMD Ryzen 7 5700X3D delivers outsized wins in the exact workloads that matter. For a general-purpose desktop with mixed productivity, media encoding, and light gaming, the Intel Core i5-13400F offers more consistent performance across a broader set of tests, with lower specified power draw and dual memory support. Both hold the 77th percentile, so neither is a weak choice. The deciding factor should be which benchmark categories match the intended daily use.
