AMD Ryzen 3 4300G vs Intel Core i7-9750H Comparison

The Intel Core i7-9750H and AMD Ryzen 3 4300G are direct rivals in the aggregate benchmark database, with both earning a 69th percentile ranking among all tested CPUs. The Intel part, a 6-core/12-thread mobile processor, wins 14 of 17 head-to-head comparisons, while the AMD 4-core/8-thread desktop chip claims only three victories. However, the nature of those wins reveals a clear split: the i7-9750H dominates compute-heavy and multi-threaded workloads, while the Ryzen 3 4300G takes the crown in encryption and single-threaded PassMark tests. Average benchmark scores are close—14,886 for Intel versus 14,503 for AMD—but the distribution of performance tells a more nuanced story.

The Verdict

The data points to a straightforward recommendation: choose the Intel Core i7-9750H for any workload that stresses multiple cores or demands raw computational throughput. It leads in every Cinebench test, with margins of 6.7% to 7% across R15, R20, and R23 in both single- and multi-core runs. The Intel chip also wins the PassMark multithread test by 8.3% and extends that lead dramatically in integer math (27.2% ahead), floating-point math (32.8% ahead), and physics (47.6% ahead). For content creation, rendering, or scientific computing, the i7-9750H is the clear choice.

The AMD Ryzen 3 4300G, by contrast, is not without merit. Its 54.1% advantage in data encryption is a massive outlier, and it edges out Intel in single-threaded PassMark by 0.9%. If your primary task is AES encryption or similar cryptographic workloads, the Ryzen 3 4300G is the better pick. It also carries a 65W TDP versus Intel’s 45W, but the data shows no performance penalty for that higher power envelope. For general desktop use where encryption is a priority, or where the unlocked multiplier is desirable, the AMD chip makes sense—but for everything else in this comparison, Intel wins.

Architecture Differences

The two processors represent fundamentally different design philosophies. The Intel Core i7-9750H is built on a 14 nm process at Intel’s foundry, using the Coffee Lake architecture (codename Coffee Lake-HR). It packs 6 cores and 12 threads, with a base clock of 2.60 GHz and a boost clock of 4.50 GHz. The L3 cache is 12 MB shared, and each core gets 64 KB of L1 and 256 KB of L2. The die size is 149 mm², and the chip uses the Intel BGA 1440 socket, marking it as a mobile part. It ships with UHD 630 integrated graphics and supports DDR4 memory over a dual-channel bus with 42.7 GB/s bandwidth.

AMD’s Ryzen 3 4300G takes a different route: a 7 nm process from TSMC, Zen 2 architecture (codename Renoir), and 4 cores with 8 threads. Base clock is 3.80 GHz, boosting to 4.00 GHz. The L3 cache is significantly smaller at 4 MB shared, but each core has 512 KB of L2—double Intel’s per-core allocation. The die size is 156 mm², slightly larger than Intel’s, and the transistor count is listed at 9,800 million. The chip uses the AMD Socket AM4 and features Radeon Vega 6 integrated graphics. Memory support is DDR4 dual-channel, but bandwidth is higher at 51.2 GB/s. Notably, the Ryzen 3 4300G has an unlocked multiplier, while the i7-9750H does not. Both support PCIe Gen 3, though AMD specifies 16 lanes on the CPU only.

Where Each One Wins

The Intel Core i7-9750H wins on almost every front. In Cinebench tests, it holds a consistent 6.7% to 7% edge across R15, R20, and R23, covering both single- and multi-core scenarios. PassMark results amplify this: the Intel chip is 60% faster in finding prime numbers, 37% faster in random string sorting, 32.8% faster in floating-point math, and 27.2% faster in integer math. The physics test shows a 47.6% Intel advantage, and data compression is 9.3% better. Even extended instructions, a niche workload, goes to Intel by 0.4%. The multithread score is 8.3% higher, and the average benchmark score is 383 points higher.

The AMD Ryzen 3 4300G wins in three specific areas. The standout is data encryption, where it beats Intel by 54.1%—a decisive margin that suggests a hardware-accelerated advantage in cryptographic operations. It also wins both PassMark single-thread tests (listed as passmark_single_thread and passmark_singlethread, both scoring 2425 versus 2404), though the margin is just 0.9%. These wins are narrow except for encryption, which is a category Apple-to-oranges outlier. The Ryzen also has a higher memory bandwidth figure (51.2 GB/s versus 42.7 GB/s), though that does not translate into benchmark victories in the tested workloads.

FAQ

Q: Which CPU is faster in multi-core workloads?

A: The Intel Core i7-9750H wins all three Cinebench multi-core tests: R15 (904 vs 845), R20 (3768 vs 3522), and R23 (8973 vs 8387), each by 7%. The PassMark multithread score also favors Intel at 10671 versus 9849 (8.3% higher).

Q: Is the AMD Ryzen 3 4300G better at anything?

A: Yes, it wins data encryption by a wide margin (8176 vs 3756, a 54.1% advantage). It also edges out Intel in PassMark single-thread score (2425 vs 2404, or 0.9% higher).

Q: How do their single-core scores compare?

A: In Cinebench, Intel wins single-core tests: R15 (127 vs 119, 6.7%), R20 (531 vs 497, 6.8%), and R23 (1266 vs 1184, 6.9%). However, in PassMark single-thread, AMD wins by a hair at 2425 versus 2404.

Q: What are the core and thread counts?

A: The Intel Core i7-9750H has 6 cores and 12 threads. The AMD Ryzen 3 4300G has 4 cores and 8 threads. The Intel part also has a larger L3 cache at 12 MB shared versus 4 MB shared on the AMD.

Q: Which chip is more power-efficient?

A: The Intel Core i7-9750H has a 45W TDP, while the AMD Ryzen 3 4300G has a 65W TDP. Despite the higher power rating, the AMD chip does not win any multi-core benchmarks, so the data does not show a power-to-performance advantage for AMD.

Q: Are these processors still in production?

A: The Intel Core i7-9750H is marked as end-of-life, released on 2019-04-22. The AMD Ryzen 3 4300G is listed as active, released on 2020-07-20. Both are in the 69th percentile of all CPUs.

Head-to-Head Benchmarks

The biggest Intel win comes in PassMark physics, where it scores 670 versus AMD’s 454—a 47.6% advantage. This is followed closely by prime number finding, where Intel’s 32 beats AMD’s 20 by a full 60%. Floating-point math shows Intel ahead 23343 to 17577 (32.8%), and integer math is 37822 to 29737 (27.2%). Random string sorting also favors Intel, 19862 to 14503 (37%). Data compression is Intel at 150443 versus 137681 (9.3%), and multithread is 10671 to 9849 (8.3%). Extended instructions are nearly identical, with Intel at 9187 and AMD at 9148 (0.4% difference).

In Cinebench, Intel maintains a uniform lead: R15 multicore is 904 to 845 (7%), R20 multicore is 3768 to 3522 (7%), and R23 multicore is 8973 to 8387 (7%). Single-core results are similarly consistent: R15 is 127 to 119 (6.7%), R20 is 531 to 497 (6.8%), and R23 is 1266 to 1184 (6.9%).

The AMD wins are concentrated in two areas. Data encryption is the headline: AMD’s 8176 crushes Intel’s 3756, a 54.1% delta. The single-thread PassMark tests are close but favor AMD, with 2425 to 2404, a 0.9% edge. These two wins, plus the duplicate single-thread listing, account for all three of AMD’s victories. The pattern is clear: Intel owns nearly every compute workload, while AMD holds a niche in encryption and a marginal single-thread PassMark advantage that does not appear in Cinebench single-core tests.
