AMD Ryzen 7 4700G vs Intel Core i9-7900X Comparison

Head-to-Head Benchmarks

The benchmark data presents a remarkably consistent picture: the Intel Core i9-7900X wins every single head-to-head comparison against the AMD Ryzen 7 4700G. Across six Cinebench tests, the Intel part takes the top spot each time, with margins that hover tightly between 3.3% and 3.4%. This uniformity is striking; the results do not show a single workload category where the Ryzen part manages to close the gap.

In Cinebench R15 multicore, the Intel Core i9-7900X scores 1782 against the AMD's 1724, a 3.4% advantage. The single-core result in the same suite shows 251 versus 243, also a 3.3% edge for Intel. Moving to Cinebench R20, the pattern repeats: 7425 versus 7186 in multicore (3.3% delta) and 1048 versus 1014 in single-core (3.4% delta). The newest suite, Cinebench R23, delivers the same story with a multicore score of 17680 versus 17111 (3.3% delta) and a single-core result of 2496 versus 2415 (3.4% delta).

The narrow, almost mechanical spread of these deltas suggests the performance gap is systemic rather than workload-specific. Every test measures roughly the same proportional difference, which points to a consistent architectural or configuration advantage rather than a benchmark that happens to favor one chip. The Intel part holds a 10-core, 20-thread configuration, while the AMD part is an 8-core, 16-thread design. Yet the multicore advantage for Intel is only about 3.3%, which implies that the Ryzen 7 4700G's higher base clock of 3.60 GHz (versus 3.30 GHz) and its Zen 2 efficiency help it stay close despite having two fewer cores and four fewer threads.

Single-core results are equally telling. The Intel boost clock of 4.50 GHz is slightly higher than the AMD boost of 4.40 GHz, and the recorded single-core deltas of 3.3% to 3.4% align with that clock differential. The Ryzen 7 4700G is not far behind in any single test, but it never leads in any recorded measurement.

Where Each One Wins

From a pure benchmark-win standpoint, the Intel Core i9-7900X wins in every measured category. That includes both multicore and single-core variants of Cinebench R15, R20, and R23. There are no recorded tests in the database where the AMD Ryzen 7 4700G takes the lead. The win count is 6 for Intel and 0 for AMD.

However, the use-case split is not merely a matter of counting wins. The Ryzen 7 4700G has characteristics that matter outside of raw render scores. It includes integrated Radeon Vega 8 graphics, which means a system can operate without a discrete GPU. The Intel part has no integrated graphics recorded in the database. For a compact desktop or an office machine where a separate graphics card is unnecessary, the AMD part offers a functional advantage that benchmarks like Cinebench do not capture.

The AMD part also operates at a much lower TDP: 65 watts versus 140 watts for Intel. This is a substantial difference in thermal and power characteristics, which can influence system design, cooling choices, and noise levels. A lower TDP typically allows for smaller cooling solutions and lower operating temperatures in constrained chassis.

Memory bandwidth is another point of differentiation. The Intel Core i9-7900X supports quad-channel DDR4 with a recorded memory bandwidth of 85.3 GB/s. The AMD Ryzen 7 4700G uses dual-channel DDR4 with a memory bandwidth of 51.2 GB/s. For workloads that are sensitive to memory bandwidth, such as certain data compression, rendering, or database operations, the Intel platform offers a clear theoretical advantage. The head-to-head render scores, however, show that this bandwidth advantage does not translate into a large Cinebench margin, likely because Cinebench is not heavily bandwidth-limited.

The AMD part is also built on a 7 nm process from TSMC, with 9,800 million transistors on a 156 mm² die. The Intel part uses Intel's 14 nm process. The process node difference is significant for efficiency, which helps explain how an 8-core chip with a higher base clock can stay within about 3.3% of a 10-core chip in multicore workloads.

The Verdict

The data in the database is unambiguous: the Intel Core i9-7900X outperforms the AMD Ryzen 7 4700G in all six recorded Cinebench benchmarks. If the decision rests solely on raw CPU rendering performance, the Intel part is the one to choose. It is ahead by 3.3% to 3.4% in every test, from Cinebench R15 single-core to Cinebench R23 multicore.

The AMD Ryzen 7 4700G, however, has its own case. It carries integrated Radeon Vega 8 graphics, a feature entirely absent from the Intel part. It also draws far less power, with a 65 watt TDP versus 140 watts, and it is built on a more advanced 7 nm process. For a system that does not need a discrete GPU, where power efficiency is a priority, or where the platform requires an AM4 motherboard with a smaller footprint, the Ryzen 7 4700G is the practical choice even though it loses every benchmark comparison.

The average benchmark scores reflect the overall positioning. The Intel part has an average benchmark score of 5120, placing it in the 60th percentile of all CPUs. The AMD part has an average score of 4949, placing it in the 59th percentile. The Intel part's nearest rivals include the AMD EPYC 7262 (0.2% ahead of the Intel part in average score), the Intel Core i7-11850HE (0.5% behind), the Intel Xeon W-2155 (0.9% behind), and the AMD Ryzen 7 PRO 5750GE (1% behind). The AMD part's nearest rivals include the Intel Xeon W-1290 (0.3% ahead), the AMD Ryzen Embedded V3C48 (0.4% behind), the Intel Core i5-12600HE (0.6% behind), and the Intel Core i7-1375PRE (0.7% behind).

In short, the Intel Core i9-7900X is the faster processor in every measured test, but the AMD Ryzen 7 4700G is the more integrated and efficient platform option. The choice depends on whether raw score or system-level features dominate the use case.

Architecture Differences

The two processors come from different architectural eras and design philosophies. The Intel Core i9-7900X is built on the Skylake architecture, specifically the Skylake-X variant, using a 14 nm process from Intel's own foundry. It belongs to the Core i9 X-Series 7th Generation and uses the Intel Socket 2066 platform. The AMD Ryzen 7 4700G uses the Zen 2 architecture, codenamed Renoir, built on a 7 nm process from TSMC. It belongs to the Ryzen 7 4000 series and uses the AMD Socket AM4 platform.

Core counts differ: the Intel part has 10 cores and 20 threads, while the AMD part has 8 cores and 16 threads. The Intel part has a base clock of 3.30 GHz and a boost clock of 4.50 GHz. The AMD part has a base clock of 3.60 GHz and a boost clock of 4.40 GHz. The AMD part runs at a higher base clock but a lower boost clock.

Cache layouts also differ. The Intel part has 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 14 MB of shared L3 cache. The AMD part has 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 8 MB of L3 cache. The Intel part has a larger L2 cache per core and a larger total L3 cache.

Memory support is another differentiator. The Intel part supports quad-channel DDR4 with a memory bandwidth of 85.3 GB/s. The AMD part supports dual-channel DDR4 with a memory bandwidth of 51.2 GB/s. Neither supports ECC memory. PCIe connectivity also differs: the Intel part provides Gen 3 with 44 lanes (CPU only), while the AMD part provides Gen 3 with 16 lanes (CPU only).

The transistor count and die size are only recorded for the AMD part: 9,800 million transistors on a 156 mm² die. The Intel part has no transistor or die size data in the database.

The AMD part includes Radeon Vega 8 integrated graphics, a feature not present on the Intel part. Both CPUs have an unlocked multiplier. The Intel part was released in June 2017 and is end-of-life, while the AMD part was released in July 2020 and remains active in production. The Intel part has a recorded launch MSRP of $999; the AMD part has no launch MSRP recorded. The process node difference, 14 nm for Intel versus 7 nm for AMD, is a fundamental architectural gap that explains the AMD part's lower TDP and higher base clock despite having fewer cores.
