AMD Ryzen 3 4300U vs Intel Core i3-1315UE Comparison

The Verdict

The benchmark data splits these two mobile processors cleanly down the middle, with each winning two of the four head-to-head tests. The AMD Ryzen 3 4300U takes both single-core Cinebench contests, while the Intel Core i3-1315UE dominates both multi-core tests. The overall average benchmark scores are nearly identical — 1742 for AMD versus 1739 for Intel — and both sit at the 41st percentile among all CPUs. Neither chip is a clear overall winner.

For users whose workloads rely on lightly threaded performance — older applications, everyday responsiveness, or tasks that scale poorly across cores — the Ryzen 3 4300U is the data-backed choice. Its single-core advantage is substantial: 92.8% ahead in Cinebench R15 single-core and 26.5% ahead in Cinebench R23 single-core. Conversely, the Core i3-1315UE is the pick for multi-threaded workloads such as video encoding, compilation, or rendering, where it leads by 7.2% in Cinebench R15 multi-core and a commanding 40.6% in Cinebench R23 multi-core.

The Ryzen 3 4300U also holds a notable edge in Geekbench, scoring 3798 multi-core and 1281 single-core, though the Intel chip lacks a directly comparable Geekbench result in the data. The i3-1315UE counters with additional Cinebench R20 results (2525 multi-core, 356 single-core) that the Ryzen lacks, suggesting the Intel part was benchmarked against a broader test suite. Given the 0.2% average score delta between them, the decision hinges entirely on which benchmark family reflects the buyer's intended usage.

Where Each One Wins

The AMD Ryzen 3 4300U wins exclusively in single-core Cinebench tests. Its 163.9 R15 single-core score versus Intel's 85 represents a 92.8% blowout — the largest margin in any test. The R23 single-core result is similarly decisive at 1074 versus 849, a 26.5% advantage. These results indicate that the Zen 2 architecture in the 4300U delivers superior instructions-per-clock in lightly threaded scenarios, despite its lower 3.70 GHz boost clock compared to Intel's 4.50 GHz.

The Intel Core i3-1315UE wins in multi-core Cinebench tests, where its six cores and eight threads (versus four cores and four threads for AMD) provide a structural advantage. The R15 multi-core margin is modest at 606 versus 562.5 (7.2%), but the R23 multi-core gap is massive: 6013 versus 3571, a 40.6% lead. The R23 test is more demanding and better reflects sustained multi-threaded performance, making this Intel's most meaningful victory. The i3-1315UE also has R20 results available (2525 multi-core, 356 single-core), indicating it was evaluated in additional scenarios where the Ryzen has no recorded data.

In terms of raw specifications, the i3-1315UE packs more cores (6 versus 4), more threads (8 versus 4), and a larger shared L3 cache (10 MB versus 4 MB). The Ryzen counters with a smaller process node (7 nm versus 10 nm) and higher memory bandwidth (51.2 GB/s versus absent data for Intel). Both ship with integrated graphics — Radeon Graphics 320SP for AMD versus UHD Graphics 64EU for Intel — but no graphics benchmarks are provided.

Architecture Differences

The two processors come from different design philosophies and manufacturing generations. The AMD Ryzen 3 4300U uses the Zen 2 architecture on a 7 nm process fabricated by TSMC, with the Renoir codename. It integrates 9,800 million transistors on a 156 mm² die. The Intel Core i3-1315UE uses the Raptor Lake architecture on a 10 nm process fabricated by Intel, with the Raptor Lake-U codename. Intel does not report transistor count or die size in the data.

Core and thread counts differ fundamentally. The Ryzen 3 4300U has 4 cores and 4 threads — no simultaneous multithreading — while the Core i3-1315UE has 6 cores and 8 threads, indicating two of its cores support hyper-threading. This explains the multi-core benchmark divergence. The Intel part's base clock is listed as 1200.00 MHz, which is unusually low compared to the Ryzen's 2.70 GHz base, though Intel's boost clock of 4.50 GHz exceeds AMD's 3.70 GHz.

Cache hierarchies also diverge significantly. The Ryzen 3 4300U has 64 KB of L1 cache per core, 512 KB of L2 per core, and 4 MB of shared L3. The Core i3-1315UE has 80 KB of L1 per core, 1.25 MB of L2 per core, and 10 MB of shared L3. The Intel part's substantially larger L2 and L3 caches likely contribute to its multi-core performance, while the AMD part's efficiency per clock drives its single-core wins.

Memory support differs as well. The Ryzen 3 4300U supports DDR4 and LPDDR4 with dual-channel memory and 51.2 GB/s bandwidth. The Core i3-1315UE supports DDR4 and DDR5, also dual-channel, but memory bandwidth is not reported. PCIe capabilities favor Intel: Gen 4 with 8 lanes (CPU only) versus Gen 3 for AMD. Neither chip supports ECC memory, and both are locked (multiplier not unlocked). The Ryzen uses AMD Socket FP6, while Intel uses BGA 1744.

A: Only the AMD Ryzen 3 4300U has Geekbench results in the data: 3798 multi-core and 1281 single-core. The Intel Core i3-1315UE has no Geekbench score recorded, so no direct comparison is possible from the provided benchmarks.

Head-to-Head Benchmarks

The four direct comparisons reveal a split personality. The most lopsided result is Cinebench R15 single-core, where the Ryzen 3 4300U scores 163.9 against the Core i3-1315UE's 85 — a 92.8% advantage. This is the clearest signal that the Zen 2 core design has superior per-thread throughput in legacy workloads. The R23 single-core test tells the same story with a smaller margin: 1074 versus 849, a 26.5% win for AMD. The shrinking delta from R15 to R23 suggests newer Cinebench versions close the gap between the architectures, but AMD still leads.

Multi-core results flip the script entirely. In Cinebench R15 multi-core, the Core i3-1315UE scores 606 versus 562.5 — a modest 7.2% edge that reflects the Intel part's extra two cores and four threads. The R23 multi-core test amplifies this advantage to a 40.6% margin, with Intel scoring 6013 versus AMD's 3571. This nearly 1.7x difference indicates that the Intel part scales far better under sustained multi-threaded load, likely due to its higher core count and larger 10 MB shared L3 cache.

The win tally is even: two tests for each processor. However, the magnitude of Intel's multi-core wins (especially the 40.6% R23 gap) is larger than AMD's single-core wins in percentage terms, except for the R15 single-core blowout. The Ryzen's 92.8% R15 single-core victory is the single largest delta in either direction, but it comes from an older, less demanding benchmark. The R23 results — both single-core and multi-core — are more representative of modern workloads, and there AMD's single-core lead is 26.5% while Intel's multi-core lead is 40.6%.

Notably, the Ryzen 3 4300U has Geekbench scores (3798 multi-core, 1281 single-core) but no R20 results, while the Core i3-1315UE has R20 scores (2525 multi-core, 356 single-core) but no Geekbench results. This uneven test coverage means the true performance relationship could shift if both chips were evaluated on identical suites. The average benchmark scores — 1742 for AMD and 1739 for Intel — suggest that, across all recorded tests, the two are effectively tied.
