AMD Ryzen 3 4300G vs Intel Core i7-8750H Comparison

Head-to-Head Benchmarks

The recorded data presents a fascinating split: the AMD Ryzen 3 4300G takes 11 of the 17 head-to-head benchmarks, but the Intel Core i7-8750H wins the remaining 6. The margins tell a more nuanced story than the raw win count suggests.

In the Cinebench suite, the AMD chip is consistently ahead, though by narrow margins. In Cinebench R15 multicore, the Ryzen 3 4300G scores 845 against 834 for the Intel part, a 1.3% advantage. The single-core result is similar: 119 versus 117, a 1.7% lead. Moving to R20, the AMD processor maintains a 1.4% edge in both multicore (3522 vs 3475) and single-core (497 vs 490). The R23 results follow the same pattern: 8387 vs 8274 in multicore and 1184 vs 1168 in single-core, both 1.4% ahead.

The Passmark suite reveals where each processor dominates. The AMD Ryzen 3 4300G crushes the Intel chip in data encryption, scoring 8176 against 3388, a staggering 141.3% delta. This is the single largest margin in the entire comparison. The AMD part also leads in extended instructions (9148 vs 8637, 5.9%) and in single-thread performance (2425 vs 2276, 6.5%). The multithread score is nearly a tie, with AMD ahead by just 0.5% (9849 vs 9799).

The Intel Core i7-8750H fights back in several computationally intensive workloads. It wins floating point math by 20.7% (22179 vs 17577), integer math by 16.5% (35629 vs 29737), and physics by 24.8% (604 vs 454). The Intel chip also takes random string sorting (18622 vs 14503, 22.1% ahead) and prime number finding (27 vs 20, 25.9% ahead). Data compression is a narrow Intel victory at 139418 vs 137681, a 1.2% margin.

The overall average benchmark score favors the AMD chip: 14503 versus 13868, which places the Ryzen 3 4300G at the 69th percentile of all CPUs while the Intel part sits at the 68th percentile. The nearest rivals data confirms these are closely matched processors, with the AMD chip's closest competitor being the AMD Ryzen 3 4100 at 14505 (0% delta), while the Intel part's nearest rival is the AMD EPYC 7443 at 13936 (-0.5%).

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 3 4300G is built on TSMC's 7 nm process node as part of the Zen 2 architecture, codenamed Renoir. It belongs to AMD's 4000 series and targets the desktop market. The chip contains 9,800 million transistors on a 156 mm² die, a remarkably dense design for its era.

The Intel Core i7-8750H, by contrast, uses Intel's 14 nm process node with the Coffee Lake architecture, specifically Coffee Lake-H. This is a mobile processor soldered to Intel BGA 1440. Its die size is 149 mm², and while the transistor count is not recorded in the database, the older process node suggests lower density.

Core configuration differs substantially. The AMD part offers 4 cores and 8 threads, while the Intel chip provides 6 cores and 12 threads. Despite the Intel chip having 50% more cores and 50% more threads, the AMD processor still manages to win the Cinebench multicore tests, which speaks to the efficiency of the Zen 2 architecture.

Cache hierarchies also diverge. Both share 64 KB of L1 cache per core. The AMD chip has 512 KB of L2 per core versus 256 KB for Intel, giving it double the L2 capacity per core. However, the Intel chip has 12 MB of shared L3 cache, triple the 4 MB shared L3 on the AMD part. This trade-off between per-core L2 and shared L3 could explain some of the workload-specific performance differences.

Clock speeds show the AMD chip running at 3.80 GHz base and 4.00 GHz boost, while the Intel part starts lower at 2.20 GHz base but boosts higher to 4.10 GHz. The TDP difference is notable: 65 watts for AMD versus 45 watts for Intel. This makes sense given the different market segments, but the AMD chip's higher TDP at a smaller process node suggests strong power efficiency.

Memory support is similar, with both supporting DDR4 in dual-channel configuration on the AMD side. The AMD processor has a recorded memory bandwidth of 51.2 GB/s, while the Intel part's bandwidth is not listed. Neither supports ECC memory. The AMD chip offers PCIe Gen 3 with 16 lanes from the CPU, while the Intel part's PCIe configuration is not recorded.

Integrated graphics differ: the AMD Ryzen 3 4300G includes Radeon Vega 6, while the Intel Core i7-8750H has UHD 630. The AMD chip has an unlocked multiplier, allowing overclocking, while the Intel part is locked. Production status also separates them, with AMD active and Intel end-of-life.

The Verdict

The data presents a compelling case for the AMD Ryzen 3 4300G as the overall benchmark winner. It secures 11 of 17 head-to-head victories, including all six Cinebench tests and the higher average benchmark score (14503 vs 13868). The AMD chip also reaches the 69th percentile of all CPUs, one point above the Intel part.

The Intel Core i7-8750H's wins are concentrated in math-heavy workloads: floating point, integer, physics, and prime numbers. These are meaningful advantages, with margins between 16.5% and 25.9%. However, the AMD chip's encryption advantage is so overwhelming that it dwarfs all other differences.

For users prioritizing Cinebench-style rendering workloads, the AMD Ryzen 3 4300G is the clear choice. Its single-thread performance is also 6.5% ahead, which benefits everyday responsiveness. The active production status and unlocked multiplier offer additional flexibility.

The Intel Core i7-8750H remains viable for specific computational tasks. Its higher core count and larger L3 cache clearly help in floating point, integer, and physics simulations. The 45-watt TDP also suggests better suitability for thermally constrained environments, though the AMD chip's 65-watt envelope is not extreme.

The end-of-life status of the Intel part is a practical consideration. The AMD chip remains in active production, which the database records. This distinction matters for system builders seeking current availability.

Where Each One Wins

AMD Ryzen 3 4300G wins in:

• All Cinebench tests (R15, R20, R23, both single and multicore), with margins from 1.3% to 1.7%
• Data encryption, with a 141.3% advantage, an exceptional outlier
• Extended instructions, 5.9% ahead
• Single-thread performance, 6.5% ahead
• Passmark multithread, though by only 0.5%

Intel Core i7-8750H wins in:

• Physics calculations, 24.8% ahead (604 vs 454)
• Prime number finding, 25.9% ahead (27 vs 20)
• Floating point math, 20.7% ahead (22179 vs 17577)
• Integer math, 16.5% ahead (35629 vs 29737)
• Random string sorting, 22.1% ahead (18622 vs 14503)
• Data compression, 1.2% ahead (139418 vs 137681)

The workload split is clear. The AMD processor excels in general-purpose computing, encryption, and single-threaded tasks. The Intel chip dominates in raw mathematical throughput and specific algorithm-heavy workloads. Users with workloads matching the Intel wins, such as scientific computing or heavy integer operations, would find the Core i7-8750H advantageous. Those with mixed or rendering-oriented workloads should prefer the Ryzen 3 4300G.
