AMD Ryzen 7 5800XT vs Intel Core 5 315 Comparison

The Verdict

The recorded data positions the AMD Ryzen 7 5800XT as the dominant performer in nearly every measured workload, winning 15 of the 17 head-to-head benchmark comparisons against the Intel Core 5 315. The AMD part delivers substantially higher multi-threaded throughput, with an average benchmark score of 29879 compared to 18188 for the Intel, placing the Ryzen in the 81st percentile of all CPUs versus the Core 5's 72nd percentile.

The Intel Core 5 315 claims only two wins, both in single-threaded PassMark tests, where it scores 4021 against the AMD's 3535, a 12.1% advantage. This makes the Intel part the better choice for workloads that are purely single-threaded and rely on that specific PassMark metric. However, the AMD processor wins every Cinebench test across R15, R20, and R23, in both single-core and multi-core variants, with deltas ranging from 83.3% to 83.7%. The Ryzen also wins all PassMark multi-threaded and math-heavy tests, including integer math with a 196.4% delta and data compression with a 140.9% delta.

For desktop users building a system around a socketed AM4 motherboard, the Ryzen 7 5800XT is the clear choice based on raw performance data. It offers 8 cores and 16 threads, an unlocked multiplier, and a 105 W TDP. The Intel Core 5 315 is a mobile part on BGA 1516, with 6 cores and 6 threads, a locked multiplier, and a 15 W TDP, making it suitable for thin-and-light laptops where power efficiency matters more than absolute performance. Users who need the single-thread PassMark edge, integrated graphics, or a low-power mobile platform would select the Intel part; anyone prioritizing multi-core compute, encryption, compression, or general desktop responsiveness from the database should select the AMD.

Architecture Differences

The AMD Ryzen 7 5800XT uses the Zen 3 architecture, codenamed Vermeer, built on a 7 nm process at TSMC. It integrates 4,150 million transistors on a 74 mm² die. The Intel Core 5 315 uses the Wildcat Lake codename with a 3 nm process at Intel, with transistor count and die size not recorded in the database.

Core and thread counts differ sharply: the AMD part has 8 cores and 16 threads, while the Intel part has 6 cores and 6 threads. The AMD processor has no integrated graphics, whereas the Intel Core 5 315 includes Intel Xe3 Graphics with 2 Xe cores. Cache hierarchies also diverge: the Ryzen 7 5800XT provides 64 KB of L1 per core, 512 KB of L2 per core, and 32 MB of shared L3. The Intel part lists 192 KB of L1 total, 2.5 MB of L2 total, and 6 MB of shared L3.

Memory support differs fundamentally. The AMD processor uses DDR4 with a dual-channel memory bus and 51.2 GB/s bandwidth, and it supports ECC memory. The Intel part supports DDR5 and LPDDR5X over a single-channel memory bus with 59.7 GB/s bandwidth, and it does not support ECC. PCIe connectivity also differs: the AMD offers Gen 4 with 20 lanes from the CPU, while the Intel offers Gen 4 with 6 lanes from the CPU.

The AMD processor uses the AMD Socket AM4, while the Intel part uses Intel BGA 1516, indicating a soldered mobile design. The AMD multiplier is unlocked, allowing overclocking; the Intel multiplier is locked. The AMD part launched on 2024-07-30 with a launch MSRP of $249, while the Intel part launched on 2026-04-15 with a launch MSRP of $340.

Where Each One Wins

The AMD Ryzen 7 5800XT wins all Cinebench tests, which measure rendering and general CPU compute. In Cinebench R23 multi-core, the AMD scores 23794 against the Intel's 12981, an 83.3% delta. In single-core R23, the AMD scores 3359 against 1832, an 83.4% delta. This pattern holds across R15 and R20, with deltas of 83.3% to 83.7%, confirming that the AMD part is faster in both lightly threaded and heavily threaded rendering workloads.

The AMD processor also dominates PassMark tests that stress data throughput. It scores 352002 in data compression versus 146143 for Intel, a 140.9% delta. Integer math shows the largest gap: 93942 versus 31690, a 196.4% delta. Random string sorting favors AMD by 104.6%, data encryption by 93%, and extended instructions by 84.7%. Floating point math and multithread tests show AMD advantages of 26.8% and 83.7%, respectively. Even the narrowest AMD win, find prime numbers at 6.3%, still favors the Ryzen.

The Intel Core 5 315 wins only the PassMark single-thread and singlethread tests, scoring 4021 in both against the AMD's 3535, a 12.1% advantage. This indicates a specific strength in lightly threaded integer workloads as measured by PassMark, but it does not translate to Cinebench single-core, where AMD leads by over 83%. The Intel part also carries integrated graphics, which the AMD lacks, making it the only option in this comparison for systems that need a GPU without a discrete card.
