AMD Ryzen 5 PRO 2400G vs Intel Core i7-7820HK Comparison

The Verdict

The benchmark data is unambiguous: the AMD Ryzen 5 PRO 2400G wins every single head-to-head comparison against the Intel Core i7-7820HK. Across six Cinebench tests, the AMD part takes all six victories, with deltas ranging from 15.2% to 15.7%. The Intel processor never once posts a higher score in the recorded tests. For any workload captured in this database, the Ryzen 5 PRO 2400G is the stronger choice.

The Ryzen 5 PRO 2400G sits at the 46th percentile of all CPUs, while the Core i7-7820HK also sits at the 46th percentile. Their average benchmark scores are close: 2101 for the AMD part versus 2048 for the Intel part. However, the head-to-head Cinebench results tell a clearer story. The AMD processor leads by roughly 15% in every measured Cinebench workload, both single-core and multi-core. The Intel chip's average score is pulled slightly upward by its Geekbench results, which are not part of the head-to-head set, but those results do not appear in the direct comparison table.

Who should pick which? The data says the Ryzen 5 PRO 2400G for anyone prioritizing Cinebench-style rendering performance, and it does so across every test generation: R15, R20, and R23. The Intel Core i7-7820HK remains a viable option only in contexts not covered by these benchmarks, since the recorded data shows no test where it wins. Its 45 W TDP is lower than the AMD part's 65 W TDP, which matters for mobile chassis design, but that is a specification difference, not a performance advantage in the measured workloads.

Where Each One Wins

The AMD Ryzen 5 PRO 2400G wins everywhere the database records a comparison. In Cinebench R15 multi-core, it scores 732 against 635, a 15.3% advantage. In Cinebench R15 single-core, it scores 103 against 89, a 15.7% advantage. Moving to Cinebench R20, the AMD part scores 3051 versus 2648 in multi-core, a 15.2% lead, and 430 versus 373 in single-core, a 15.3% lead. Cinebench R23 shows the same pattern: 7266 versus 6306 in multi-core, 15.2% ahead, and 1025 versus 890 in single-core, 15.2% ahead.

The Intel part's only recorded non-Cinebench results are in Geekbench: 4173 multi-core and 1273 single-core. These are not part of the head-to-head table, so the database does not credit them as wins. In the six direct comparisons, the Intel Core i7-7820HK has zero wins. The AMD processor wins all six.

For use-case planning, the implication is straightforward. Rendering workloads that scale with Cinebench scores will favor the AMD processor. Single-threaded tasks, often considered an Intel strength historically, also favor the AMD part in this comparison. The 15% single-core advantage in R23 (1025 versus 890) is particularly notable, as it suggests the Ryzen 5 PRO 2400G is not merely a multi-core specialist in this pairing.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen 5 PRO 2400G uses the Zen architecture, codenamed Raven Ridge, built on a 14 nm process at GlobalFoundries. It packs 4,950 million transistors on a 210 mm² die. The Intel Core i7-7820HK uses Kaby Lake, specifically Kaby Lake-H, also on a 14 nm process but fabricated by Intel, with a 126 mm² die size. Intel does not list a transistor count in the database.

Cache layouts differ significantly. The AMD part has 96 KB of L1 cache per core, 512 KB of L2 per core, and 4 MB of shared L3. The Intel part has 64 KB of L1 per core, 256 KB of L2 per core, and 8 MB of shared L3. The Intel chip has twice the L3 cache, but the AMD chip has larger per-core L1 and L2 allocations. The total L3 field is null for both, so the shared values are the only comparable figures.

Memory support also diverges. The AMD processor supports DDR4 only, with dual-channel memory and a recorded memory bandwidth of 46.9 GB/s. It also supports ECC memory. The Intel processor supports both DDR3 and DDR4, dual-channel, but has no recorded memory bandwidth figure and does not support ECC. PCIe connectivity differs: the Ryzen 5 PRO 2400G provides Gen 3 with 8 lanes from the CPU, while the Core i7-7820HK provides Gen 3 with 16 lanes from the CPU.

Integrated graphics separate them clearly. The AMD part carries Radeon RX Vega 11, while the Intel part carries Intel HD Graphics 630. Both are unlocked in terms of multiplier, and both use four cores and eight threads. The AMD part's base clock is 3.60 GHz with a 3.90 GHz boost; the Intel part's base clock is 2.90 GHz with the same 3.90 GHz boost. The lower base clock on the Intel chip may explain part of its deficit in sustained workloads.

The AMD processor is a desktop part on AMD Socket AM4, still in active production. The Intel processor is a mobile part on Intel BGA 1440, and its production status is end-of-life. The AMD part released on 2018-05-09, while the Intel part released on 2017-01-02. The Intel part has a launch MSRP of $378, while the AMD part has no recorded launch MSRP.

FAQ

Head-to-Head Benchmarks

The head-to-head table contains six entries, and the AMD Ryzen 5 PRO 2400G wins every one. The smallest margin is 15.2%, appearing in Cinebench R20 multi-core, R23 multi-core, and R23 single-core. The largest margin is 15.7%, in Cinebench R15 single-core.

Cinebench R15 multi-core: the AMD part scores 732, the Intel part scores 635. That is a 97-point gap, a 15.3% delta. This test favors processors with strong sustained multi-threaded throughput, and the AMD part delivers.

Cinebench R15 single-core: the AMD part scores 103, the Intel part scores 89. The 14-point gap translates to 15.7%, the largest relative margin in the entire comparison. This is a surprising result for a Zen-based part against Kaby Lake, but the recorded data is clear.

Cinebench R20 multi-core: the AMD part scores 3051, the Intel part scores 2648. The 403-point gap is a 15.2% delta. The pattern from R15 repeats almost exactly.

Cinebench R20 single-core: the AMD part scores 430, the Intel part scores 373. The 57-point gap is a 15.3% delta.

Cinebench R23 multi-core: the AMD part scores 7266, the Intel part scores 6306. The 960-point gap is a 15.2% delta.

Cinebench R23 single-core: the AMD part scores 1025, the Intel part scores 890. The 135-point gap is a 15.2% delta.

The consistency of the margins is striking. Across six tests spanning three Cinebench generations, the AMD processor maintains a lead between 15.2% and 15.7%. There is no test where the Intel chip narrows the gap below 15%. The Intel part's Geekbench scores, 4173 multi-core and 1273 single-core, are recorded in its benchmark list but do not appear in the head-to-head table, so they cannot offset any of these Cinebench losses in the direct comparison.

Nearest rival data places both processors in similar company. The AMD part's closest rivals include the Intel Core i3-8350K with an average score of 2096, a 0.3% delta, and the AMD Ryzen 7 1700X with an average score of 2094, also a 0.3% delta. The Intel part's closest rivals include the Intel Xeon E3-1270 v5 with an identical average score of 2048, a 0% delta, and the AMD Ryzen 5 7520U at 2046, a 0.1% delta. These figures confirm that both processors perform near their respective peer groups, with the AMD part slightly higher on average.
