AMD Ryzen 7 PRO 3700 vs Intel Core i9-9900X Comparison

Head-to-Head Benchmarks

The recorded benchmark data shows a clean sweep for the AMD Ryzen 7 PRO 3700 across all six shared Cinebench tests. The largest margin appears in Cinebench R15 multi-core, where the AMD part scores 1955 against the Intel Core i9-9900X's 1851, a 5.6% advantage. The single-core R15 test follows a similar pattern: 275 versus 261, a 5.4% lead for AMD.

Moving to the newer Cinebench versions, the story remains consistent. In Cinebench R20 multi-core, the Ryzen 7 PRO 3700 posts 8146, while the i9-9900X manages 7713, again a 5.6% difference. The R20 single-core result shows the AMD processor at 1149 against Intel's 1088, with the same 5.6% delta. Cinebench R23 multi-core reinforces the trend: 19397 for AMD versus 18365 for Intel, a 5.6% gap. The R23 single-core test shows 2738 against 2592, also a 5.6% margin.

Notably, the i9-9900X has two additional Geekbench entries in the database, but no comparable Geekbench scores exist for the Ryzen 7 PRO 3700, so those results cannot be used for a direct head-to-head comparison. Across all tests where both processors have recorded scores, the AMD chip wins every round, which translates to 6 wins for the Ryzen 7 PRO 3700 and 0 for the i9-9900X. The consistency of the 5.6% delta across R20 and R23 suggests a stable performance advantage rather than a test-specific anomaly.

The average benchmark score also favors AMD. The Ryzen 7 PRO 3700 holds an average of 5610 across its recorded tests, while the i9-9900X averages 5301. This places the AMD part in the 61st percentile of all CPUs in the database, slightly above the Intel part's 60th percentile. The nearest rivals for the AMD chip include the Intel Core i7-12700T at 5606 (0.1% behind) and the Intel Atom x7433RE at 5601 (0.2% behind), showing that the Ryzen 7 PRO 3700 sits in a dense cluster of comparable processors. For the Intel i9-9900X, the closest competitors are the AMD Ryzen Threadripper 1920X at 5306 (0.1% ahead of the Intel part) and the AMD EPYC 7281 at 5315 (0.3% ahead), indicating the i9-9900X is slightly below its nearest performance peers.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 7 PRO 3700 uses the Zen 2 architecture with the Matisse codename, built on a 7 nm process at TSMC. It packs 3,800 million transistors into a 74 mm² die. The Intel Core i9-9900X, by contrast, uses the older Skylake architecture with the Skylake-X codename, fabricated on Intel's 14 nm process. The database does not list transistor count or die size for the Intel part.

Core counts differ significantly. The Ryzen 7 PRO 3700 has 8 cores and 16 threads, while the i9-9900X offers 10 cores and 20 threads. Despite having fewer cores, the AMD processor still outperforms the Intel part in every recorded multi-core benchmark, which points to superior per-core efficiency. The base clocks are close: 3.60 GHz for AMD versus 3.50 GHz for Intel. The boost clocks are also near each other, with the Intel part slightly higher at 4.50 GHz versus 4.40 GHz for AMD.

Cache hierarchies reveal different strategies. Both processors have 64 KB of L1 cache per core. The L2 cache differs: the Ryzen 7 PRO 3700 has 512 KB per core, while the i9-9900X has a larger 1 MB per core. The L3 cache is where AMD takes a clear lead in total capacity: 32 MB for the Ryzen 7 PRO 3700 versus 19.25 MB shared for the i9-9900X. This larger L3 cache likely contributes to the AMD part's performance advantage in cache-sensitive workloads.

Memory support also diverges. Both support DDR4 memory, but the Ryzen 7 PRO 3700 uses a dual-channel memory bus with 51.2 GB/s bandwidth, while the i9-9900X uses a quad-channel bus with 85.3 GB/s bandwidth. The Intel part has a theoretical memory bandwidth advantage of roughly 67%, yet this does not translate into benchmark wins in the recorded data. Neither processor supports ECC memory.

PCI Express capabilities differ by generation and lane count. The Ryzen 7 PRO 3700 provides PCIe Gen 4 with 24 lanes from the CPU, while the i9-9900X provides PCIe Gen 3 with 44 lanes. The AMD part offers a newer PCIe standard, while the Intel part offers more lanes. The socket and platform are entirely different: AMD uses Socket AM4, and Intel uses Socket 2066. The production status also differs, with the Ryzen 7 PRO 3700 listed as active and the i9-9900X marked as end-of-life.

FAQ

Q: Which processor wins in multi-core performance?

A: The AMD Ryzen 7 PRO 3700 wins every multi-core test in the database. In Cinebench R23 multi-core, it scores 19397 versus 18365 for the Intel Core i9-9900X, a 5.6% advantage. The R20 multi-core result shows a similar gap: 8146 versus 7713.

Q: How do single-core scores compare?

A: The AMD processor also leads in single-core tests. In Cinebench R23 single-core, the Ryzen 7 PRO 3700 scores 2738 against 2592 for the i9-9900X, a 5.6% margin. The R15 single-core test shows 275 versus 261, a 5.4% lead.

Q: Does the Intel processor have more cores?

A: Yes, the Intel Core i9-9900X has 10 cores and 20 threads, while the AMD Ryzen 7 PRO 3700 has 8 cores and 16 threads. Despite having fewer cores, the AMD part still beats the Intel part in all recorded multi-core benchmarks.

Q: What are the TDP ratings for each processor?

A: The AMD Ryzen 7 PRO 3700 has a TDP of 65 watts, while the Intel Core i9-9900X has a TDP of 165 watts. The AMD part delivers higher benchmark scores with a substantially lower thermal design power.

Q: Which processor has more L3 cache?

A: The AMD Ryzen 7 PRO 3700 has 32 MB of L3 cache, while the Intel Core i9-9900X has 19.25 MB of shared L3 cache. The AMD part has roughly 66% more L3 cache capacity.

Q: How do the memory buses differ?

A: The AMD Ryzen 7 PRO 3700 uses a dual-channel memory bus with 51.2 GB/s bandwidth. The Intel Core i9-9900X uses a quad-channel memory bus with 85.3 GB/s bandwidth. The Intel part has higher theoretical memory bandwidth, but this does not produce a benchmark win.

The Verdict

The benchmark data clearly favors the AMD Ryzen 7 PRO 3700. It wins all six shared Cinebench tests with deltas ranging from 5.4% to 5.6%. The AMD processor achieves this with 8 cores versus 10 cores for Intel, a 65-watt TDP versus 165 watts, and a smaller process node at 7 nm versus 14 nm. The average benchmark score of 5610 for AMD exceeds the Intel part's 5301, and the AMD chip sits at the 61st percentile of all CPUs, one point higher than the Intel part's 60th percentile.

For users who prioritize raw compute performance in the tested workloads, the Ryzen 7 PRO 3700 is the stronger choice based on the recorded data. It also offers a more modern platform with PCIe Gen 4 support and an active production status. The Intel Core i9-9900X provides more cores, more PCIe lanes, and higher memory bandwidth on paper, but these advantages do not translate into wins in the Cinebench suite. The Intel part is also listed as end-of-life, which may matter for long-term system planning. The database shows no scenario where the i9-9900X outperforms the Ryzen 7 PRO 3700 in the shared tests.

Where Each One Wins

The AMD Ryzen 7 PRO 3700 wins in every benchmark category where both processors have recorded scores. This includes Cinebench R15, R20, and R23 in both single-core and multi-core variants. The margins are consistent, mostly at 5.6%, with the R15 single-core test showing a slightly smaller 5.4% gap. The AMD part also holds a higher average benchmark score (5610 versus 5301) and a higher percentile ranking (61st versus 60th). For users running applications similar to the Cinebench workload, the Ryzen 7 PRO 3700 is the clear performer.

The Intel Core i9-9900X does not record a single benchmark win against the AMD part in the shared test suite. Its theoretical advantages lie in areas not represented by the benchmark wins: 10 cores versus 8, 44 PCIe Gen 3 lanes versus 24 PCIe Gen 4 lanes, and 85.3 GB/s memory bandwidth versus 51.2 GB/s. The Intel part also has a higher boost clock at 4.50 GHz versus 4.40 GHz. These factors could matter in workloads that benefit from additional cores, more PCIe lanes for expansion, or higher memory bandwidth, but the database does not include benchmark results that demonstrate such an advantage. The i9-9900X also carries a launch MSRP of $989, while the AMD part has no listed launch MSRP. For any use case measured in the database, the AMD Ryzen 7 PRO 3700 is the recommended choice.
