AMD Ryzen 5 PRO 2400G vs Intel Core i7-8705G Comparison

Head-to-Head Benchmarks

The head-to-head data presents a consistent and unambiguous picture. Across every Cinebench iteration recorded in the database, the AMD Ryzen 5 PRO 2400G outperforms the Intel Core i7-8705G. The benchmark results show the AMD part winning all six recorded tests, with the Intel part recording zero wins.

The margins are remarkably uniform. In the Cinebench R15 suite, the AMD processor scores 732 points in the multicore test against Intel's 651, a 12.4% advantage. The single-core R15 test shows a similar gap: 103 versus 91, which translates to a 13.2% lead for AMD. This is the largest single delta in the entire head-to-head comparison.

Moving to Cinebench R20, the pattern repeats. The AMD Ryzen 5 PRO 2400G scores 3051 in multicore performance, while the Intel Core i7-8705G manages 2714. That is again a 12.4% difference. In single-core R20, the scores are 430 and 383 respectively, a 12.3% margin. The consistency across these different workloads suggests the performance gap is structural rather than workload-specific.

The most recent benchmarks in the database, Cinebench R23, confirm the trend. The AMD chip scores 7266 in multicore and 1025 in single-core. The Intel chip scores 6464 and 912 respectively. Both deltas sit at 12.4%. It is notable that the percentage gap does not widen or narrow as the workload becomes more demanding; it stays fixed around the 12% to 13% range across all six tests.

The average benchmark score in the database reinforces this hierarchy. The AMD Ryzen 5 PRO 2400G posts an average score of 2101, while the Intel Core i7-8705G averages 2058. When placed against their respective nearest rivals, both processors sit in the 46th percentile of all CPUs, indicating they occupy a similar tier in the overall performance distribution. However, the direct comparison shows the AMD part has a clear edge.

Architecture Differences

The architectural split between these two processors is substantial, despite both being built on a 14 nm process node. The AMD Ryzen 5 PRO 2400G uses the Zen architecture with the Raven Ridge codename, fabricated by GlobalFoundries. The Intel Core i7-8705G uses the Kaby Lake architecture with the Kaby Lake G codename, fabricated by Intel's own foundries.

The transistor counts differ sharply. AMD lists 4,950 million transistors on a 210 mm² die. Intel does not provide a transistor count in the database, but the die size is recorded at 125 mm². This means the AMD die is nearly 70% larger in physical area, which correlates with its larger cache allocation.

Cache configurations show meaningful divergence. The AMD processor carries 96 KB of L1 cache per core, 512 KB of L2 per core, and 4 MB of shared L3 cache. The Intel processor carries 64 KB of L1 per core, 256 KB of L2 per core, but doubles the L3 to 8 MB shared. So Intel has more last-level cache, while AMD has more per-core L1 and L2. The total cache strategy is different: AMD spreads its cache closer to the cores, while Intel concentrates it in a larger shared pool.

Memory bandwidth also favors AMD. The Ryzen 5 PRO 2400G supports dual-channel DDR4 with a recorded bandwidth of 46.9 GB/s. The Intel Core i7-8705G also supports dual-channel DDR4 but is limited to 38.4 GB/s. That is an 8.5 GB/s deficit for Intel, which could matter in bandwidth-sensitive workloads.

ECC memory support is another differentiator. AMD enables ECC memory, while Intel does not. This positions the AMD part for reliability-focused scenarios where memory error correction is required.

The integrated graphics are entirely different. AMD pairs the CPU with Radeon RX Vega 11, a substantial integrated GPU. Intel uses HD Graphics 630. The database does not include graphics benchmarks, but the naming alone indicates a significant capability gap. The AMD part is a Desktop segment product on AMD Socket AM4, while the Intel part is a Mobile segment product on Intel BGA 2270. The Intel chip is also a soldered mobile part, not socketed.

Production status differs as well. The AMD Ryzen 5 PRO 2400G is listed as Active, while the Intel Core i7-8705G is listed as End-of-life. The AMD part also has an unlocked multiplier, while the Intel multiplier is locked. The release dates show the Intel part came first in January 2018, with AMD following in May 2018.

The clock speed trade-off is worth noting. Intel has the higher boost clock by 0.20 GHz, but AMD has a 0.50 GHz higher base clock. In sustained workloads, the base clock often matters more, which may explain the AMD advantage in the benchmark results.

Where Each One Wins

The recorded benchmark data shows the AMD Ryzen 5 PRO 2400G winning every single Cinebench test. There is no recorded benchmark in the database where the Intel Core i7-8705G takes the lead. This makes the use-case split somewhat one-sided from a pure CPU performance perspective.

For multi-threaded workloads, the AMD part is consistently ahead. The Cinebench R15, R20, and R23 multicore tests all show a 12.4% advantage for AMD. This suggests that rendering, video encoding, and other parallel workloads will see a measurable benefit from choosing the AMD processor.

For single-threaded workloads, the AMD part also wins, but the margins vary slightly. The R15 single-core test shows a 13.2% lead, while R20 shows 12.3% and R23 shows 12.4%. Even though Intel has a higher boost clock, the AMD part still comes out ahead in these tests. This implies that the higher base clock on AMD, combined with its per-core cache configuration, offsets Intel's boost advantage.

The Intel Core i7-8705G does have advantages in specific areas, but not in CPU benchmark scores. It has double the L3 cache, which could benefit certain cache-sensitive workloads that the Cinebench suite does not capture. Its smaller die size at 125 mm² suggests it may be more power-efficient per unit area, though the TDP is identical at 65 watts for both. The Intel part also has an earlier release date, but it is now end-of-life, while AMD remains active.

From a platform perspective, the AMD part offers ECC memory support and an unlocked multiplier, making it more flexible for overclocking and reliability-focused builds. The Intel part is a soldered mobile chip with a locked multiplier, which limits its appeal for enthusiasts.

The Verdict

The data points to a clear conclusion. The AMD Ryzen 5 PRO 2400G is the superior CPU in every recorded benchmark. It wins all six head-to-head tests with margins between 12.3% and 13.2%. Its average benchmark score of 2101 exceeds the Intel Core i7-8705G's 2058 by a meaningful margin.

For a user building a desktop system, the AMD part is the obvious choice. It is socketed on AM4, has an unlocked multiplier, supports ECC memory, and remains in active production. Its integrated Radeon RX Vega 11 graphics outclass Intel's HD Graphics 630, at least by name. The 46.9 GB/s memory bandwidth gives it a further edge.

The Intel Core i7-8705G is a mobile part that is end-of-life. Its only recorded advantages are a higher boost clock of 4.10 GHz and double the L3 cache at 8 MB. Yet these advantages do not translate into benchmark wins. The Intel chip loses every Cinebench test despite the boost clock and cache lead.

The verdict is simple: the AMD Ryzen 5 PRO 2400G should be the pick for anyone choosing between these two based on the available data. The Intel Core i7-8705G may have specific niche uses where its larger L3 cache or soldered mobile form factor matters, but the recorded benchmarks do not show any scenario where it outperforms AMD. The 12.4% multicore advantage across all three Cinebench versions is decisive and consistent.
