AMD Ryzen AI 7 450G vs Intel Core 5 315 Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive overall margin for the AMD Ryzen AI 7 450G, which wins 10 of the 11 shared benchmark comparisons. The most striking result is in integer math, where the AMD part scores 99,732 against Intel’s 31,690, a 214.7% advantage. This is the largest single-test gap in the dataset and reflects a fundamental difference in parallel throughput capability.

Data compression follows a similar pattern. The Ryzen AI 7 450G scores 402,831 versus 146,143 for the Core 5 315, a 175.6% lead. Random string sorting shows a 143.1% gap, with 42,663 versus 17,551. Extended instruction workloads favor AMD by 114.7%, at 28,223 versus 13,143. These four tests all involve heavy multi-threaded workloads, and the pattern is consistent: the AMD processor delivers more than double the throughput in several cases.

Multithreaded performance overall lands at 30,422 for the Ryzen AI 7 450G, nearly double the Intel part’s 15,272, a 99.2% difference. Floating point math shows a 50.1% lead, 63,683 versus 42,441. Data encryption is closer but still firmly in AMD’s favor, 18,937 versus 11,119, a 70.3% margin. Physics simulation scores 1,440 versus 1,163, a 23.8% advantage for AMD.

The single-thread comparison is much tighter. The Ryzen AI 7 450G scores 4,309, while the Core 5 315 scores 4,021, a 7.2% difference. This indicates that while AMD holds the lead in single-core performance, it is not overwhelming. The Intel part’s single-thread score is competitive, which matters for lightly threaded applications.

The Intel Core 5 315 does claim one win. In the find prime numbers test, it scores 112 against AMD’s 87, a 22.3% margin in Intel’s favor. This is an isolated result, but it is a genuine victory and suggests that the Intel architecture handles this specific workload more efficiently. Across all other shared tests, AMD’s lead ranges from modest to massive.

The average benchmark score for the AMD Ryzen AI 7 450G is 63,331, placing it at the 93rd percentile among all recorded CPUs. The Intel Core 5 315 averages 18,188, at the 72nd percentile. This places the two processors in entirely different performance tiers, with AMD’s average score being roughly 3.5 times higher. The nearest rivals for the AMD part include the Intel Core Ultra 7 265HX, which scores 63,173 (0.2% lower), and the AMD Ryzen AI Max PRO 390 at 63,765 (0.7% higher). The Intel Core 5 315 sits alongside the AMD EPYC 9274F at 18,189 and the Intel Core i7-9700 at 18,180, effectively matching both within 0.1%.

The Verdict

The data supports a clear split: the AMD Ryzen AI 7 450G is the stronger compute processor in nearly every measurable way. Its 8 cores and 16 threads provide substantial multi-threaded headroom, and the 99.2% lead in the multithread PassMark test confirms that. The 214.7% advantage in integer math and 175.6% lead in data compression are not marginal gains; they represent a different class of throughput. Anyone running CPU-bound parallel workloads, content creation tasks, or heavy data processing should favor the AMD part based solely on these numbers.

The Intel Core 5 315 has a narrower role. Its single-thread score of 4,021 is within 7.2% of the AMD part, and its win in the prime number test shows that it can outperform in specific algorithmic patterns. The Intel processor also carries a 15 W TDP versus AMD’s 65 W, which makes it the more power-efficient choice for constrained thermal environments. The data does not show the Intel part as competitive in raw performance, but it does indicate a viable option for systems where power draw is the primary constraint.

For buyers prioritizing raw benchmark performance, the Ryzen AI 7 450G wins decisively. For buyers prioritizing low power consumption in a mobile form factor, the Core 5 315 is the logical pick. Neither processor is a substitute for the other based on the recorded scores.

Architecture Differences

The two processors come from different process nodes. AMD uses TSMC’s 4 nm process for the Ryzen AI 7 450G, while Intel uses its own 3 nm process for the Core 5 315. The AMD part is built on the Gorgon Point codename, part of the Ryzen AI 400 generation with Zen 5 and Zen 5c cores. Intel’s part uses the Wildcat Lake codename, from the Core 5 generation. The AMD processor has 8 cores and 16 threads, while Intel offers 6 cores and 6 threads, meaning no simultaneous multi-threading on the Intel side.

Cache layouts differ significantly. The AMD processor provides 80 KB of L1 per core and 1 MB of L2 per core, with 8 MB of L3. The Intel part lists 192 KB of L1 total, 2.5 MB of L2, and 6 MB of shared L3. The per-core L2 allocation on AMD is larger, which contributes to its multi-threaded performance advantage.

Memory architecture also diverges. Both support DDR5 and LPDDR5X, but AMD uses a dual-channel memory bus with 89.6 GB/s of bandwidth, while Intel uses a single-channel bus with 59.7 GB/s. This 33% bandwidth difference likely plays a role in the large gaps seen in memory-sensitive benchmarks like data compression and integer math. AMD also supports ECC memory, which Intel does not.

PCIe connectivity differs as well. The AMD part offers Gen 4 with 12 CPU lanes, while Intel provides Gen 4 with 6 CPU lanes. The integrated graphics are also different: AMD uses the Radeon 860M, while Intel uses Xe3 Graphics with 2 Xe cores. The AMD processor is unlocked for overclocking, while the Intel part is locked. The AMD socket is AMD Socket AM5, and the Intel socket is BGA 1516, reflecting the desktop versus mobile market positioning.
