AMD Ryzen 7 5700X3D vs Intel Core i7-13620H Comparison

The Intel Core i7-13620H and AMD Ryzen 7 5700X3D are both 77th-percentile performers, but they achieve that status through entirely different strengths. The data shows the Intel chip wins 10 benchmark comparisons, while the AMD chip takes 13, yet the margin of victory in each case tells the real story. The i7-13620H dominates in low-thread-count and floating-point workloads, while the 5700X3D crushes multi-threaded rendering and physics tests by margins as large as 55.8%.

Head-to-Head Benchmarks

The 3DMark suite is decisively in Intel’s favor. The i7-13620H leads by 25.4% in single-thread performance (1008 vs 804) and by 24.6% in 2-thread workloads (1963 vs 1575). The gap narrows as threads scale, but Intel still holds a 4.3% edge at 16 threads (7056 vs 6764) and a 6.3% edge at max threads (7178 vs 6755). This pattern suggests the Raptor Lake architecture translates single-core efficiency into consistent multi-thread scaling within this benchmark.

PassMark results split sharply. The i7-13620H wins floating-point math by 28.5% (59762 vs 46492) and single-thread by 20.8% (3589 vs 2970). However, the 5700X3D takes the integer math test by a hair-thin 0.4% margin (81257 vs 80948), making that result effectively a tie. The AMD chip also leads in multithread by 8.1% (26318 vs 24192), data compression by 8.4% (307237 vs 281335), and random string sorting by 6.7% (31492 vs 29395).

The Cinebench results are where the 5700X3D runs away with it. In Cinebench R23 multicore, the AMD chip scores 22366 versus Intel’s 15176, a 32.1% advantage. The single-core gap is even more pronounced: 3157 vs 1833, a 41.9% lead. Cinebench R20 shows a similar pattern with AMD ahead by 11.6% in multicore (9393 vs 8305) and 11.5% in single-core (1325 vs 1172). The only Cinebench test Intel wins is R15 multicore, by a narrow 1.2% (2281 vs 2254).

AMD’s biggest single victory comes in PassMark’s find prime numbers test, where it scores 224 against Intel’s 99 — a 55.8% blowout. The 5700X3D also wins physics by 37.8% (2686 vs 1671), extended instructions by 17.4% (21202 vs 17513), and data encryption by 17.1% (18788 vs 15568). Intel’s largest win outside of 3DMark is the 28.5% floating-point margin.

The Verdict

The data points to two distinct buyer profiles. The Intel Core i7-13620H is the pick for anyone whose work or play leans on light-thread responsiveness — its 25.4% single-thread 3DMark win and 20.8% PassMark single-thread lead make it the smoother choice for everyday application snappiness and older games that rely on one or two strong cores. It also holds a 28.5% edge in floating-point math, which can matter for scientific or financial workloads.

The AMD Ryzen 7 5700X3D is the clear winner for sustained multi-core throughput. Its 32.1% Cinebench R23 multicore advantage and 37.8% physics lead indicate superior performance in rendering, video encoding, and simulation tasks. The 55.8% margin in prime-number finding suggests the 96 MB of shared L3 cache gives it a massive edge in cache-sensitive workloads. If the task can use all 16 threads, the 5700X3D is the stronger choice.

The overall average benchmark scores are nearly identical — 24911 for Intel versus 24709 for AMD — so neither chip is a slouch. But the distribution of wins matters more than the aggregate. Intel’s 10 wins are concentrated at low thread counts; AMD’s 13 wins are spread across heavy compute tasks. Choose based on workload, not headline numbers.

Where Each One Wins

The i7-13620H wins in scenarios where latency and clock speed dominate. Its 4.90 GHz boost clock versus the 5700X3D’s 4.10 GHz aligns with its 3DMark single-thread and 2-thread victories. This makes it the better fit for lightly-threaded applications, legacy software, and games that haven’t been optimized for many cores. The floating-point math advantage also points to CAD or simulation software that relies on FPU throughput.

The 5700X3D wins in cache-heavy and fully-threaded workloads. Its 96 MB of shared L3 cache — four times Intel’s 24 MB — explains the data compression, random string sorting, and prime number results. The physics benchmark win suggests better performance in game physics engines and rigid-body simulations. Video editors and 3D renderers will see the biggest benefit from its 22366 Cinebench R23 multicore score.

Consider the platform implications. The i7-13620H is a mobile part on Intel BGA 1744 with a 45 W TDP, while the 5700X3D is a desktop chip on AMD Socket AM4 with a 105 W TDP. The Intel chip includes UHD Graphics 770, so it can run without a discrete GPU. The AMD chip has no integrated graphics, requiring a separate video card. The 5700X3D supports ECC memory and PCIe Gen 4 with 20 lanes; the i7 uses PCIe Gen 5 with 8 lanes.

Architecture Differences

The two chips come from fundamentally different design philosophies. Intel’s Raptor Lake-H architecture uses a 10 nm process and packs 10 cores with 16 threads, relying on a hybrid layout to balance performance and efficiency. AMD’s Zen 3 architecture, codenamed Vermeer, uses TSMC’s 7 nm node and offers 8 cores with 16 threads. The AMD chip has 8,850 million transistors on a 74 mm² die; no transistor or die size data is provided for the Intel part.

Cache configurations diverge sharply. Intel provides 80 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3. AMD provides 64 KB of L1 per core, 512 KB of L2 per core, and 96 MB of shared L3. The 72 MB difference in L3 is the most significant architectural gap and directly correlates with AMD’s wins in cache-sensitive benchmarks.

Process node and foundry also differ. Intel fabricates its chip on its own 10 nm process, while AMD uses TSMC’s 7 nm node. The 5700X3D’s smaller node likely contributes to its higher base clock of 3.00 GHz versus Intel’s 2.40 GHz, though Intel’s boost clock of 4.90 GHz exceeds AMD’s 4.10 GHz.

Platform features set them apart further. The Intel chip supports PCIe Gen 5 with 8 CPU lanes; the AMD chip uses PCIe Gen 4 with 20 CPU lanes. AMD supports ECC memory and lists 51.2 GB/s memory bandwidth, while Intel does not support ECC and provides no bandwidth figure. The Intel part includes integrated UHD Graphics 770; the AMD part has none.

Specification Differences

The core and thread counts differ: Intel has 10 cores and 16 threads, AMD has 8 cores and 16 threads. Both processors are locked (multiplier unlocked: false), so neither offers manual overclocking via multiplier adjustment.

Clock speeds vary significantly. The Intel chip has a 2.40 GHz base clock and 4.90 GHz boost. The AMD chip has a 3.00 GHz base and 4.10 GHz boost. Intel’s higher boost clock explains its single-thread wins in 3DMark and PassMark, while AMD’s higher base clock helps with sustained all-core loads.

Thermal design power differs by 60 W: Intel is rated at 45 W, AMD at 105 W. This reflects the desktop versus mobile market split. The Intel part uses the Intel BGA 1744 socket, while the AMD part uses AMD Socket AM4.

Memory support diverges: Intel accepts DDR4 and DDR5, AMD only DDR4. Both run dual-channel. The AMD chip lists 51.2 GB/s memory bandwidth; Intel has no listed bandwidth figure.

PCIe capabilities differ: Intel offers Gen 5 with 8 lanes, AMD offers Gen 4 with 20 lanes. The Intel chip includes UHD Graphics 770; the AMD chip has no integrated graphics. Market segments also differ: Intel is mobile, AMD is desktop.

Release timing and pricing differ. Intel launched on 2023-01-03 with a launch MSRP of $502. AMD launched on 2024-01-07 with a launch MSRP of $249. Both are active production parts. The part numbers are SRMJ0 for Intel and 100-000001503100-100001503WOF for AMD.

ECC memory support is exclusive to AMD. The Intel chip does not support ECC. This makes the 5700X3D more suitable for error-sensitive compute tasks, though the platform choice will ultimately dictate whether ECC is usable.
