AMD Ryzen 5 5500X3D vs Intel Core 5 315 Comparison

The AMD Ryzen 5 5500X3D and the Intel Core 5 315 represent two very different philosophies for a six-core processor. The AMD part is a desktop chip built on a mature platform, while the Intel part is a low-power mobile processor. The benchmark data shows a clear split: the AMD Ryzen 5 5500X3D dominates in multi-threaded and memory-heavy tasks, while the Intel Core 5 315 takes a decisive lead in single-threaded performance. The recorded measurements place the AMD chip in the 85th percentile of all CPUs, with an average benchmark score of 37018. The Intel chip sits in the 72nd percentile, with an average score of 18188. These figures establish the baseline for a comparison that reveals significant architectural and performance differences.

Head-to-Head Benchmarks

The most lopsided result in the head-to-head data is the PassMark physics test. The AMD Ryzen 5 5500X3D scores 2282, while the Intel Core 5 315 manages only 1163. That is a 96.2% advantage for the AMD processor, the largest delta in any of the recorded tests. Physics workloads often scale with thread count and cache capacity, both of which favor the AMD part.

The integer math test also shows a massive gap. AMD scores 60033 versus Intel's 31690, a 89.4% difference. This is the strongest indicator of the AMD chip's raw multi-core execution advantage. The data compression test follows a similar pattern, with AMD at 230392 and Intel at 146143, a 57.6% lead. Encryption workloads show AMD ahead by 25.6%, with scores of 13967 and 11119 respectively. Extended instruction performance favors AMD by 21.2%, with a score of 15925 against 13143. Prime number finding, a test that stresses integer throughput and cache latency, gives AMD a 51.8% lead with 170 versus 112.

The multithread score is another clear win for AMD. The Ryzen 5 5500X3D records 20363, compared to 15272 for the Intel Core 5 315, a 33.3% advantage. Random string sorting shows AMD ahead by 34.9%, with scores of 23675 and 17551. Across eight of the eleven recorded head-to-head benchmarks, the AMD processor comes out on top, with the largest wins in physics, integer math, and data compression.

The Intel Core 5 315 wins the remaining three tests, and it wins them convincingly. The single-thread benchmark is the most important of these. Intel scores 4021, while AMD scores 2941, a 26.9% advantage. This result appears twice in the data, once as passmark_single_thread and once as passmark_singlethread, confirming the same measurement. The floating point math test also goes to Intel, with a score of 42441 against AMD's 34511, an 18.7% lead. These two wins show that the Intel chip has a stronger per-core execution capability, despite having fewer threads.

The head-to-head tally is 8 wins for AMD and 3 for Intel. The magnitude of AMD's wins, however, is generally larger than Intel's. The physics delta of 96.2% and the integer math delta of 89.4% are far greater than Intel's 26.9% single-thread margin. This suggests that the AMD processor's advantages are not just broad but also deep in the workloads where it excels.

The Verdict

The data points to two distinct use cases. The AMD Ryzen 5 5500X3D is the stronger processor for multi-threaded work. It wins the multithread test by 33.3%, and its 96.2% lead in physics and 89.4% lead in integer math indicate a substantial capacity for parallel workloads. The 12 threads, compared to the Intel chip's 6, provide a structural advantage that shows up across most of the benchmark suite. The AMD chip also delivers a 57.6% win in data compression, a task that benefits from both thread count and large cache.

The Intel Core 5 315 is the stronger processor for single-threaded responsiveness. Its 4021 single-thread score beats the AMD chip's 2941 by 26.9%. The 18.7% lead in floating point math also indicates strong per-core capability. For workloads that rely on a single thread or lightly threaded execution, the Intel part has the edge.

The average benchmark scores confirm the overall hierarchy. AMD's 37018 average is more than double Intel's 18188. The nearest rival data for AMD shows a tight cluster: the AMD Ryzen 5 5600F scores 36945, a 0.2% difference, the AMD Ryzen AI 7 PRO 450 scores 37093, a -0.2% difference, the Intel Core Ultra 5 225 scores 36938, a 0.2% difference, and the Intel Core i9-12900T scores 37112, a -0.3% difference. The Ryzen 5 5500X3D sits squarely in that group, performing within fractions of a percent of those four chips.

The Intel Core 5 315's nearest rivals are a different class entirely. The AMD EPYC 9274F matches its 18189 average exactly, the Intel Core i7-9700 scores 18180, the Intel Core i7-1365U scores 18177, and the AMD Ryzen 7 5700U scores 18176. These are all within 0.1% of the Intel chip's average. This places the Core 5 315 in the same performance tier as older desktop parts and mid-range mobile chips, rather than competing with the top of the desktop stack.

Architecture Differences

The two processors come from different manufacturing and design lineages. The AMD Ryzen 5 5500X3D uses the Zen 3 architecture, codenamed Vermeer, built on a 7 nm process at TSMC. The Intel Core 5 315 uses a 3 nm process at Intel, with the codename Wildcat Lake. This is a two-generation process node gap in Intel's favor, which explains the Intel chip's higher boost clock of 4.40 GHz against AMD's 4.00 GHz. The base clocks differ even more dramatically: Intel runs at 1.50 GHz, while AMD runs at 3.00 GHz. The Intel chip's lower base clock and higher boost clock reflect a design aimed at power efficiency rather than sustained all-core throughput.

Both chips have 6 cores. The AMD part has 12 threads, while the Intel part has 6 threads. This means the AMD chip can process twice as many concurrent threads, which is the primary reason for its dominance in multi-threaded tests. The AMD chip has a 96 MB shared L3 cache, a hallmark of the X3D series, while the Intel chip has a 6 MB shared L3 cache. That is a 16x difference in L3 capacity. The per-core L1 and L2 caches also differ. AMD lists 64 KB of L1 per core and 512 KB of L2 per core. Intel lists 192 KB of L1 and 2.5 MB of L2 in total. AMD's die size is recorded as 74 mm².

Memory support is another major split. The AMD processor uses DDR4 with a dual-channel memory bus and a bandwidth of 51.2 GB/s. The Intel processor supports DDR5 and LPDDR5X, but only with a single-channel memory bus, achieving a bandwidth of 59.7 GB/s. Despite the single channel, Intel's newer memory technology gives it a higher peak bandwidth figure. AMD supports ECC memory, while Intel does not. PCIe connectivity also differs: AMD offers Gen 4 with 20 lanes from the CPU, while Intel offers Gen 4 with only 6 lanes.

The integrated graphics situation is stark. The AMD chip has no integrated graphics, listed as N/A. The Intel chip includes Intel Xe3 Graphics with 2 Xe cores. This makes the Intel part a complete package for a mobile system without a discrete GPU, while the AMD part requires a separate graphics card.

The socket and form factor are completely different. AMD uses Socket AM4, a desktop socket with a 105 W TDP. Intel uses BGA 1516, a soldered mobile package with a 15 W TDP. That is a 90 W difference in thermal design power. The Intel chip is designed for thin-and-light laptops, while the AMD chip is designed for desktop towers. The release dates also differ: AMD launched on June 4, 2025, and Intel on April 15, 2026. The Intel chip has a launch MSRP of $340.

Where Each One Wins

The AMD Ryzen 5 5500X3D wins in every multi-threaded category measured. The multithread score of 20363 beats Intel's 15272 by 33.3%. The physics test, which often reflects real-time simulation and gaming physics, shows a 96.2% advantage. Integer math, a proxy for general arithmetic processing, is 89.4% faster. Data compression and encryption workloads also favor AMD by 57.6% and 25.6% respectively. The 12 threads and the 96 MB L3 cache are the structural reasons for these wins. The 85th percentile ranking also places the AMD chip far above the Intel chip's 72nd percentile in the global CPU distribution.

The Intel Core 5 315 wins in single-threaded performance and floating point math. The 4021 single-thread score is 26.9% ahead of AMD. The floating point score of 42441 is 18.7% ahead. The 4.40 GHz boost clock and the 3 nm process node support these results. The Intel chip also brings integrated graphics, which the AMD chip lacks, and a much lower TDP of 15 W versus 105 W. For a mobile system running lightly threaded applications, the Intel part is the stronger choice. The single-channel memory bus and 6 MB L3 cache limit its multi-threaded potential, but the data shows it handles single-thread tasks efficiently. The 59.7 GB/s memory bandwidth also gives it a slight peak bandwidth edge over AMD's 51.2 GB/s, despite the single channel.

The AMD chip's nearest rivals all sit within 0.3% of its average score, showing that it is a stable, well-positioned desktop part. The Intel chip's nearest rivals, including the Intel Core i7-9700 and the AMD Ryzen 7 5700U, show that it competes with previous-generation desktop and current mobile parts. The data does not suggest a single winner across all workloads. It suggests a desktop processor with massive cache and thread advantages versus a mobile processor with per-core speed and efficiency advantages. The choice depends entirely on the workload and the platform.
