AMD Ryzen 5 PRO 2400G vs Intel Core i5-7640X Comparison

Where Each One Wins

The recorded head-to-head data is decisive: the AMD Ryzen 5 PRO 2400G wins all six benchmark comparisons against the Intel Core i5-7640X. There is no benchmark category where the Intel part takes a victory, whether the workload is single-threaded or multi-threaded. The AMD chip leads by a consistent margin across all Cinebench versions, with deltas between 17.0% and 17.5% in every test.

The Intel Core i5-7640X, despite its higher clock speeds and X-Series positioning, does not secure a single win in the database. Its average benchmark score sits at 2167, while the Ryzen 5 PRO 2400G averages 2101. In percentile terms, the Intel chip ranks at the 47th percentile of all CPUs, and the AMD part sits at the 46th percentile, so they occupy the same performance tier overall. The AMD advantage is concentrated specifically in the Cinebench workload suite, where its extra threads and architecture characteristics yield consistent leads.

For users who prioritize the Cinebench family of benchmarks, the AMD Ryzen 5 PRO 2400G is the clear choice. The Intel chip can still be relevant for other tasks, but within the measured data, the AMD processor outperforms it in every recorded test. The absence of any Intel wins means there is no "use case split" to describe from the benchmark results alone; the AMD part is categorically ahead in this dataset.

Architecture Differences

The two processors come from fundamentally different design philosophies, even though both are built on a 14 nm process. The Intel Core i5-7640X uses Kaby Lake architecture with the Kaby Lake-X codename, part of the Core i5 X-Series 7th Generation lineup. It has 4 cores and 4 threads, with no simultaneous multithreading. The AMD Ryzen 5 PRO 2400G uses Zen architecture under the Raven Ridge codename, part of the 2000 series, and offers 4 cores with 8 threads thanks to SMT.

Clock speeds favor the Intel chip on paper. The i5-7640X runs at a 3.90 GHz base clock and boosts to 4.30 GHz, while the Ryzen 5 PRO 2400G starts at 3.60 GHz and boosts to 3.90 GHz. However, the AMD processor compensates with its thread count and cache layout. The Intel chip has 64 KB of L1 cache per core and 256 KB of L2 per core, with 6 MB of shared L3. The AMD chip has 96 KB of L1 per core, 512 KB of L2 per core, but only 4 MB of shared L3, a smaller pool of last-level cache.

The manufacturing foundries differ: Intel fabricates its chip in-house, while AMD uses GlobalFoundries. The AMD die is 210 mm² with 4,950 million transistors, whereas Intel reports no die size or transistor count in the database. Memory support shows another split: the Intel chip uses quad-channel memory, while the AMD chip uses dual-channel. The AMD part also includes integrated Radeon RX Vega 11 graphics, which the Intel chip lacks entirely. ECC memory support is present on the AMD side but absent on the Intel side. The PCIe implementation also differs, with AMD offering Gen 3 with 8 CPU lanes, while Intel lists Gen 3 without a lane count.

The Intel chip has a 112 W TDP, nearly double the AMD part's 65 W TDP. Both processors have unlocked multipliers, and both target the desktop market segment.

Head-to-Head Benchmarks

Every recorded benchmark shows the AMD Ryzen 5 PRO 2400G ahead of the Intel Core i5-7640X. In Cinebench R15 multi-core, the AMD chip scores 732 against 607 for Intel, a 17.1% lead. In the single-core version of R15, AMD wins 103 to 85, a 17.5% margin. Moving to Cinebench R20, the AMD part scores 3051 in multi-core versus 2533, a 17% difference, and 430 versus 357 in single-core, also 17%. The R23 results follow the same pattern: AMD scores 7266 versus 6031 in multi-core, and 1025 versus 851 in single-core, both with a 17% delta.

The consistency of the 17% margin across all three Cinebench versions is notable. It suggests that the performance gap is structural rather than workload-specific. The AMD chip wins by a similar proportion in both single-threaded and multi-threaded tests, which means the advantage is not simply a matter of having more threads. In the Geekbench tests that appear only for the Intel chip, the i5-7640X records 5137 multi-core and 1736 single-core, but there are no corresponding AMD Geekbench scores in the database, so no head-to-head comparison is possible for that suite.

The AMD processor's single-core wins are particularly interesting given that the Intel chip has a higher boost clock, 4.30 GHz versus 3.90 GHz. The recorded data shows that raw clock speed does not translate into a benchmark advantage in this matchup. The AMD architecture extracts more performance per cycle, or the benchmark conditions favor its design, or both.

The Verdict

The data points to a single conclusion: the AMD Ryzen 5 PRO 2400G is the stronger performer in this comparison, at least within the Cinebench benchmark family. It wins all six recorded head-to-head tests, with consistent 17% margins in both single-core and multi-core workloads. The AMD chip also offers integrated graphics, ECC memory support, and a lower 65 W TDP, making it a more versatile and power-efficient option.

The Intel Core i5-7640X has higher clock speeds and a larger L3 cache, but these advantages do not translate into benchmark wins. Its 4-thread configuration and higher 112 W TDP place it at a disadvantage in multi-threaded workloads, and even in single-threaded tests, the AMD part is faster according to the recorded scores. The Intel chip occupies a similar overall percentile rank, 47th versus 46th for AMD, but the head-to-head results are unambiguous.

Users who depend on Cinebench scores should select the AMD Ryzen 5 PRO 2400G without hesitation. Users who need integrated graphics or ECC memory also have no choice but the AMD part, since the Intel chip lacks both. Users who specifically require quad-channel memory or the Intel Socket 2066 platform might consider the i5-7640X, but the benchmark data offers no performance justification for that choice. The verdict from the database is clear: the AMD Ryzen 5 PRO 2400G is the superior processor in every measured category.
