AMD Ryzen 7 2800H vs Intel Core i3-N305 Comparison

Head-to-Head Benchmarks

The benchmark data presents a split picture between the AMD Ryzen 7 2800H and the Intel Core i3-N305, with the Intel chip dominating most Cinebench tests but the AMD part scoring a major victory in the newest multi-core workload. Across the six recorded head-to-head results, the Intel Core i3-N305 wins five tests, while the AMD Ryzen 7 2800H takes one, and that single win is substantial.

The most striking result is in Cinebench R23 multi-core, where the AMD Ryzen 7 2800H scores 6922 against the Intel Core i3-N305's 5092, a 35.9% advantage for AMD. This is the largest delta in either direction across the entire comparison. The older Cinebench R20 multi-core test tells a different story: the Intel Core i3-N305 posts 3349 versus AMD's 2907, a 13.2% lead for Intel. The pattern repeats in Cinebench R15 multi-core, with Intel ahead at 829 versus 697, a 15.9% margin. The shifting results between R15, R20, and R23 multi-core benchmarks suggest the two processors respond very differently to workload scaling, with the AMD chip appearing to gain ground as the test becomes more demanding.

Single-core results are consistently in favor of Intel, though the margin shrinks in newer tests. In Cinebench R15 single-core, the Intel Core i3-N305 scores 164.7 against AMD's 98, a massive 40.5% lead. Cinebench R20 single-core narrows that gap somewhat: Intel posts 472 versus AMD's 410, a 13.1% advantage. The closest single-core contest is in Cinebench R23, where Intel edges ahead with 995 versus AMD's 977, a slim 1.8% margin. The trend across these three generations of Cinebench single-core tests suggests the Intel architecture holds a consistent, though diminishing in newer workloads, edge in lightly threaded performance.

The Intel Core i3-N305 also carries two additional Geekbench results in the database, scoring 3881 in multi-core and 1049 in single-core, while the AMD Ryzen 7 2800H has no recorded Geekbench scores. These absence of direct comparison points in Geekbench limits the cross-check, but the recorded Cinebench data provides enough signal for analysis.

Looking at the broader database context, the AMD Ryzen 7 2800H holds an average benchmark score of 2002 and sits in the 45th percentile of all CPUs. Its nearest rivals are tightly clustered around that average: the Intel Core i5-8400T at 2001 with a 0% delta, the Intel Core i5-8400H at 2003 with a -0.1% delta, the Intel Xeon D-1712TR at 2004 also at -0.1%, and the Intel Core i5-8300H at 2005 with a -0.2% delta. The Intel Core i3-N305, by contrast, averages 1979 and sits in the 44th percentile, with nearest rivals including the Intel Core i5-7600K at 1976 (0.1% delta), the Intel Xeon E3-1245 v5 at 1973 (0.3%), the AMD Ryzen Embedded V1756B at 1986 (-0.3%), and the Intel Core i5-8279U at 1987 (-0.4%). The overall averages place the AMD part marginally ahead of the Intel chip by 23 points, a difference of roughly 1.1%, which is within the noise floor of the nearest rival clusters.

The head-to-head deltas in the Cinebench tests, however, show real divergence beyond those averages, with the R23 multi-core gap of 35.9% being far larger than the overall average gap between the two parts would suggest. The data indicates that application-specific behavior can deviate sharply from aggregate scores, which is exactly why workload-specific benchmarks matter for the final pick.

The Intel Core i3-N305 wins the Cinebench R15, R20, and R23 single-core tests, plus both the R23 single-core and the R23 single-core results in its favor outside the multi-core exception. The AMD Ryzen 7 2800H counters with just the Cinebench R23 multi-core result, but that single victory carries a 35.9% delta, the largest in the set.

Where Each One Wins

The AMD Ryzen 7 2800H demonstrates its strongest showing in the Cinebench R23 multi-core workload, where its 6922 score represents a 35.9% advantage over the Intel Core i3-N305. This result stands out as the only test where the AMD processor leads, and the margin is decisive. The data implies that the AMD chip excels in scenarios that stress sustained multi-threaded execution over extended durations, given the R23 test format, which aligns with its older Zen architecture design and dual-channel memory bus configuration with DDR4 support.

The Intel Core i3-N305 claims wins across the older Cinebench iterations, covering both single-core and multi-core variants of R15 and R20. In R15, the Intel chip leads by 15.5% in multi-core at 829 versus 697, and by 40.5% in single-core at 164.7 versus 98. In R20, Intel holds a 13.2% multi-core edge with 3349 against 2907, and a 13.1% single-core lead with 472 versus 410. The consistent single-core wins across two generations, plus a 1.6% edge in R23 single-core versus AMD's 1.8% delta in the same test, show Intel's Gracemont architecture handles lightly threaded code with efficiency across varied workloads, though the R23 single-core gap drops to a narrow 1.8% margin, making it a near-tie in that test.

For short bursts of single-threaded tasks, Intel's lead is undeniable, especially in R15 single-core at 40.5%, but the AMD part remains competitive in R23 single-core at 977 versus 995 995 with Intel at 995, a two percent gap. The Intel chip wins the most individual benchmark tests, five out of six, indicating its broad applicability across most Cinebench scenarios, while the AMD processor wins the most demanding multi-core test by a wide margin.

The Verdict

The data suggests a workload-dependent choice between these two mobile processors. The AMD Ryzen 7 2800H is the clear pick for scenarios that prioritize the Cinebench R23 multi-core workload, where its 6922 score beats the Intel Core i3-N305's 5092 by 35.9%. The AMD part also carries a slightly higher average benchmark score of 2002 versus Intel's 1979, and a higher percentile ranking at 45th versus 44th, indicating marginally better overall standing in the database. Its dual-channel memory support with DDR4, compared to Intel's single-channel DDR4 or DDR5, may contribute to its multi-core strength in certain applications.

The Intel Core i3-N305 is the better choice for single-threaded tasks and older Cinebench versions, where it wins all single-core tests, with the R15 margin being the largest at 40.5%. Its Cinebench R20 multi-core lead of 13.2% and R15 multi-core lead of 15.9% also suggest it handles typical multi-core loads effectively, though the R23 multi-core result is a notable exception. The Intel chip also offers a larger shared L3 cache at 6 MB versus 4 MB, and its Gracemont architecture with 8 cores and 8 threads provides parallel capabilities that the AMD chip matches with 4 cores and 8 threads.

Users focused on the latest multi-core rendering workloads should lean toward the AMD Ryzen 7 2800H based on its R23 performance. Users prioritizing single-core speed or compatibility with older Cinebench versions should select the Intel Core i3-N305, which dominates across most recorded tests. The near-tie in R23 single-core at 977 versus 995, a 1.8% delta, means the choice in that specific test comes down to other factors like cache size or memory channel configuration.

The Intel Core i3-N305 carries a recorded launch MSRP of $309, which can be stated once as its launch MSRP, though the AMD part has no recorded launch MSRP.
