Architecture Differences

The AMD Ryzen 7 5705GE uses the Zen 3 architecture under the Cezanne codename, produced on a 7 nm process at TSMC. It integrates 10,700 million transistors on a die size of 180 mm². The Intel Core 5 315 uses the Wildcat Lake codename, produced on a 3 nm process at Intel's own foundry. No transistor count or die size data is recorded for the Intel part.

Cache structures differ substantially. The AMD processor has 64 KB of L1 cache per core and 512 KB of L2 cache per core, resulting in 8 MB of total L2 across 8 cores, plus a 16 MB L3 cache. The Intel processor lists 192 KB of L1 cache, 2.5 MB of L2 cache, and 6 MB of shared L3 cache. The AMD part therefore provides a larger aggregate cache pool, which can benefit workloads with repeated data access patterns.

Memory architecture also separates the two. AMD uses DDR4 with a dual-channel memory bus and a recorded bandwidth of 51.2 GB/s. Intel uses DDR5 or LPDDR5X with a single-channel memory bus and a recorded bandwidth of 59.7 GB/s. Despite the single-channel limitation, the Intel part has a higher theoretical memory bandwidth figure. ECC memory is not supported by either processor.

PCIe connectivity differs. The AMD processor provides Gen 3 with 16 lanes from the CPU, while the Intel processor provides Gen 4 with 6 lanes from the CPU. The integrated graphics are also different: AMD uses Radeon Graphics with 512 shader processors, while Intel uses Xe3 Graphics with 2 Xe cores.

The AMD processor has an unlocked multiplier, while the Intel processor is locked. The AMD part is socketed for AM4, while the Intel part is in a BGA 1516 package, which means it is soldered to the board.

Where Each One Wins

The Intel Core 5 315 wins in single-threaded and lightly threaded workloads. Its benchmark results show a Cinebench R23 single-core score of 1832, a Cinebench R20 single-core score of 769, and a Cinebench R15 single-core score of 184. PassMark single-thread results also favor the Intel chip at 4021. These figures indicate that the Intel part delivers strong per-core performance, likely aided by its higher memory bandwidth and newer process node.

The AMD Ryzen 7 5705GE wins in heavily threaded workloads due to its 8 cores and 16 threads versus the Intel part's 6 cores and 6 threads. The AMD processor also has a much higher base clock of 3.80 GHz versus 1.50 GHz, which helps in sustained multi-threaded tasks. Its larger L3 cache of 16 MB versus 6 MB on the Intel part gives it an advantage in workloads that benefit from larger working sets.

The Intel part is a mobile processor with a 15 watt TDP, making it suited for low-power and thermally constrained environments. The AMD part is a desktop processor with a 35 watt TDP, which allows for more sustained performance but requires a proper desktop cooling solution. The Intel part's single-channel memory bus may be a drawback in memory-sensitive tasks, but its higher bandwidth figure of 59.7 GB/s partially compensates.

Specification Differences

The two processors differ across nearly every major specification field. The AMD Ryzen 7 5705GE has 8 cores and 16 threads, while the Intel Core 5 315 has 6 cores and 6 threads. Base clocks are 3.80 GHz for AMD and 1.50 GHz for Intel. Boost clocks are 4.60 GHz for AMD and 4.40 GHz for Intel. TDP is 35 watts for AMD and 15 watts for Intel.

The sockets differ completely: AMD uses Socket AM4, while Intel uses BGA 1516. The process nodes are 7 nm (TSMC) for AMD and 3 nm (Intel) for Intel. The AMD part has a transistor count of 10,700 million and a die size of 180 mm², while the Intel part has no recorded transistor count or die size.

Cache allocations differ. AMD has 64 KB L1 per core, 512 KB L2 per core, and 16 MB L3. Intel has 192 KB L1 total, 2.5 MB L2 total, and 6 MB shared L3. Memory support is DDR4 dual-channel for AMD versus DDR5 and LPDDR5X single-channel for Intel. Memory bandwidth is 51.2 GB/s for AMD versus 59.7 GB/s for Intel. PCIe is Gen 3 with 16 lanes for AMD versus Gen 4 with 6 lanes for Intel.

Integrated graphics differ: Radeon Graphics 512SP for AMD versus Intel Xe3 Graphics with 2 Xe for Intel. The AMD processor has an unlocked multiplier; the Intel processor does not. The launch MSRP for the Intel Core 5 315 is $340. The AMD part has no recorded launch MSRP.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between these two processors. However, recorded benchmark data for the Intel Core 5 315 provides a basis for interpreting its performance profile. The Intel part achieves a Cinebench R23 multi-core score of 12981, a Cinebench R20 multi-core score of 5452, and a Cinebench R15 multi-core score of 1308. Its PassMark multi-thread score is 15272.

The AMD Ryzen 7 5705GE has no recorded benchmark scores in the database, so a direct numeric comparison is not possible. The Intel part's average benchmark score is 18188, and it sits at the 72nd percentile of all CPUs. Its nearest rivals include the AMD EPYC 9274F at 18189 (0% delta), the Intel Core i7-9700 at 18180 (0% delta), the Intel Core i7-1365U at 18177 (0.1% delta), and the AMD Ryzen 7 5700U at 18176 (0.1% delta). These rivals are effectively tied in average score, which places the Intel Core 5 315 in a competitive performance band.

The Intel part's PassMark sub-scores show its character. Data compression scores 146143, data encryption scores 11119, extended instructions score 13143, find prime numbers scores 112, floating point math scores 42441, integer math scores 31690, physics scores 1163, and random string sorting scores 17551. The single-thread score of 4021 is strong relative to its multi-thread score, confirming that the Intel part favors single-core performance.

Given the AMD part's 8 cores and 16 threads, the expected outcome in multi-threaded benchmarks would favor AMD, but the absence of recorded AMD benchmark scores means the exact margin cannot be stated. The Intel part's 6 cores and 6 threads limit its parallel throughput, but its 3 nm process and higher memory bandwidth give it an edge in tasks that depend on single-core speed.

The Verdict

The data shows two processors with opposite design priorities. The AMD Ryzen 7 5705GE is a desktop chip with 8 cores, 16 threads, a 35 watt TDP, and an unlocked multiplier. It targets multi-threaded workloads and users who want a socketed AM4 processor with upgrade flexibility. Its 16 MB L3 cache and dual-channel DDR4 support suit it to applications that scale with core count and cache capacity.

The Intel Core 5 315 is a mobile chip with 6 cores, 6 threads, a 15 watt TDP, and a locked multiplier. Its 3 nm process, single-channel DDR5 or LPDDR5X support, and recorded benchmark scores place it in the 72nd percentile of all CPUs. Its single-thread performance, as shown by the 4021 PassMark single-thread score and 1832 Cinebench R23 single-core score, is its strongest asset. The launch MSRP is $340.

For users who prioritize multi-threaded throughput and desktop expandability, the AMD part is the logical choice based on its 8-core, 16-thread configuration and larger cache. For users who prioritize single-core performance and low power consumption in a mobile form factor, the Intel part is the better fit. The Intel part's 15 watt TDP and BGA package target laptops and compact systems, while the AMD part's 35 watt TDP and AM4 socket target desktop builds. The absence of AMD benchmark scores in the database means the exact performance delta between the two cannot be quantified, but the specification differences clearly indicate distinct use cases.
