Architecture Differences

The AMD Ryzen 7 PRO 4750G is built on TSMC's 7 nm process with a die size of 156 mm² and 9,800 million transistors. The Intel Core i9-9900KS uses Intel's 14 nm process with a 180 mm² die, and the database records no transistor count for it. The process node difference is substantial: 7 nm versus 14 nm, which helps explain the AMD part's 65 W TDP against Intel's 127 W TDP.

The Ryzen 7 PRO 4750G belongs to the Zen 2 architecture under the Renoir codename. The Core i9-9900KS is Coffee Lake, specifically Coffee Lake-R, which is a refresh of Intel's earlier architecture. The AMD chip sits on the AM4 socket, while Intel uses Socket 1151. AMD's L3 cache is 8 MB, whereas Intel's L3 cache is 16 MB shared. Per-core L2 differs too: AMD provides 512 KB per core, Intel provides 256 KB per core. Both have 64 KB L1 per core.

Memory bandwidth favors AMD at 51.2 GB/s versus Intel's 42.7 GB/s, though both use dual-channel DDR4. AMD includes ECC memory support, a feature absent on the Intel part. Integrated graphics differ as well: AMD packs Radeon Vega 8, Intel uses UHD 630. Both offer PCIe Gen 3 with 16 CPU lanes. The AMD processor has a locked multiplier, while the Intel Core i9-9900KS has an unlocked multiplier. Production status also separates them: AMD is active, Intel is end-of-life.

The release dates show AMD arriving nearly nine months later: July 20, 2020 for the Ryzen 7 PRO 4750G, October 27, 2019 for the Core i9-9900KS. The Intel part carries a launch MSRP of $513; the AMD part has no recorded launch MSRP.

The Verdict

The data paints a clear picture for Cinebench workloads: the AMD Ryzen 7 PRO 4750G outperforms the Intel Core i9-9900KS by 4.6% in every Cinebench R15, R20, and R23 test, both multi-core and single-core. This consistency across six benchmarks suggests a structural advantage in rendering and compute tasks, not a fluke. The AMD part achieves this with a 65 W TDP against Intel's 127 W TDP, making it the more power-efficient choice for sustained workloads.

However, the Intel Core i9-9900KS dominates in Geekbench multi-core by 22.8%, a significant margin that cannot be ignored. For workloads that resemble Geekbench's mixed integer and floating-point patterns, Intel is the stronger performer. The single-core Geekbench result also favors Intel, though by a narrower 5.1%.

The average benchmark scores place AMD slightly ahead overall: 4,879 versus 4,738. Both processors sit at the 59th percentile, indicating they target the same performance tier. The Ryzen 7 PRO 4750G offers ECC memory support, a feature that matters for workstation reliability, while the Core i9-9900KS offers an unlocked multiplier for enthusiasts. Given that the Intel chip is end-of-life and the AMD chip remains active, the AMD part has the longer support horizon.

Who should pick which? For Cinebench-heavy workflows, power-sensitive builds, or ECC requirements, the AMD Ryzen 7 PRO 4750G is the data-backed choice. For applications that mirror Geekbench's multi-threaded patterns, or for overclocking flexibility, the Intel Core i9-9900KS holds the edge. The Intel part's 5.00 GHz boost clock also makes it attractive for lightly threaded tasks where raw frequency matters, though the Cinebench single-core results show AMD still wins those tests.

Head-to-Head Benchmarks

The AMD Ryzen 7 PRO 4750G sweeps the Cinebench suite with a uniform 4.6% margin across all six tests. In Cinebench R15 multi-core, AMD scores 1,734 against Intel's 1,657. The single-core R15 test shows 244 versus 233, a 4.7% win. Moving to R20, AMD posts 7,225 multi-core and 1,019 single-core, while Intel records 6,907 and 974. The R23 results continue the pattern: 17,204 versus 16,446 in multi-core, and 2,428 versus 2,321 in single-core. These margins are small but remarkably consistent, suggesting the Zen 2 architecture delivers a steady efficiency advantage across rendering generations.

The Intel Core i9-9900KS answers in Geekbench. The multi-core test gives Intel a decisive 9,771 score against AMD's 7,547, a 22.8% gap. This is the largest performance difference in the entire comparison. The single-core Geekbench test also goes to Intel with 1,715 versus 1,628, a 5.1% lead. Interestingly, the Geekbench multi-core result contradicts the Cinebench multi-core result, highlighting how different benchmark suites stress the chips in different ways. Cinebench scales well with AMD's memory bandwidth and cache layout, while Geekbench's workload distribution favors Intel's higher frequency and larger shared L3 cache.

The final tally stands at 6 wins for AMD and 2 for Intel. The AMD part's average benchmark score of 4,879 edges out Intel's 4,738, though both land at the 59th percentile. The nearest rivals in the database reinforce the positioning: the AMD chip sits within 1.1% of the Ryzen 7 5800HS and within 1.1% of the Xeon W-1290, while the Intel chip trades places with the Core i7-6950X and EPYC 7252 within 0.8%. Neither chip breaks dramatically away from its peers, but the AMD part's consistency in Cinebench and its active production status make it the more future-proof option in the database's view.
