AMD Ryzen 7 8700G vs Intel Core 5 315 Comparison

Head-to-Head Benchmarks

The recorded benchmark data shows a decisive overall advantage for the AMD Ryzen 7 8700G, which wins 11 of the 15 head-to-head comparisons. The Intel Core 5 315 takes 4 wins, but the margin of victory in those cases is narrow, while the AMD processor's wins are frequently massive.

The largest single gap appears in PassMark integer math, where the AMD Ryzen 7 8700G scores 103,107 against 31,690 for the Intel Core 5 315, a delta of 225.4%. This is the most extreme difference in the entire dataset and reflects the AMD processor's substantial advantage in basic arithmetic throughput.

PassMark data compression shows a similarly dominant result. The AMD part scores 386,811 versus 146,143, a 164.7% lead. Random string sorting follows at 162.2% in favor of AMD, with scores of 46,025 and 17,551 respectively. Extended instructions go to AMD by 121.2% (29,067 versus 13,143), and the multithread workload shows a 107.5% advantage (31,690 versus 15,272).

Cinebench R15 multicore shows a 105.9% lead for AMD (2,693 versus 1,308), while data encryption comes in at 105.4% (22,842 versus 11,119). Even Cinebench R23 multicore, which narrows the gap, still favors AMD by 31.9% (17,128 versus 12,981). Floating point math favors AMD by 50.4% (63,815 versus 42,441), and physics shows a 41.6% advantage (1,647 versus 1,163).

The Intel Core 5 315's four wins are all in single-thread or light-thread workloads, and each is small. PassMark single-thread shows Intel ahead by 2.3% (4,021 versus 3,928), and the same delta appears in the duplicate singlethread entry. Cinebench R23 single-core goes to Intel by just 0.8% (1,832 versus 1,817). The single largest Intel win is in PassMark find prime numbers, where Intel scores 112 against AMD's 103, an 8% margin.

Architecture Differences

The two processors come from entirely different design points. The AMD Ryzen 7 8700G uses the Zen 4 architecture under the Phoenix codename, built on a 4 nm process at TSMC. It packs 8 cores and 16 threads, enabling simultaneous multithreading. The Intel Core 5 315 uses the Wildcat Lake codename on a 3 nm Intel process, with 6 cores and 6 threads, meaning no hyperthreading support.

The cache layouts differ structurally. AMD allocates 64 KB of L1 per core and 1 MB of L2 per core, with 16 MB of shared L3. Intel provides 192 KB of L1 total, 2.5 MB of L2, and 6 MB of shared L3. The per-core L2 approach on AMD gives each of its 8 cores a full 1 MB, while Intel's aggregate figures must be divided across 6 cores.

Memory architecture diverges sharply. AMD uses dual-channel DDR5 with a recorded bandwidth of 83.2 GB/s. Intel supports DDR5 and LPDDR5X but only through a single-channel memory bus, yielding 59.7 GB/s. That bandwidth gap helps explain AMD's large leads in memory-sensitive workloads like data compression and random string sorting.

PCIe lane counts also differ. AMD provides 20 Gen 4 lanes from the CPU, while Intel provides 6 Gen 4 lanes. For a desktop processor with discrete GPU ambitions, that difference is substantial. The AMD part has an unlocked multiplier, while Intel's is locked.

The integrated graphics differ as well. AMD uses the Radeon 780M, while Intel uses Xe3 Graphics with 2 Xe cores. Neither benchmark set in this comparison includes graphics tests, so the data cannot quantify that difference.

The AMD processor is a desktop part on Socket AM5, with a 65 W TDP and a launch MSRP of $329. The Intel processor is a mobile part on BGA 1516, with a 15 W TDP and a launch MSRP of $340. The Intel part releases later in the database timeline and targets a different physical form factor.

Where Each One Wins

The AMD Ryzen 7 8700G wins across every multithreaded and throughput-oriented workload in the dataset. The 8-core, 16-thread configuration with dual-channel memory produces leads ranging from 31.9% in Cinebench R23 multicore to 225.4% in integer math. Any workload that scales with core count, memory bandwidth, or both will favor AMD heavily.

The Intel Core 5 315 wins only in narrow single-thread scenarios. Its 4.40 GHz boost clock, despite a much lower 1.50 GHz base, allows it to edge out AMD in PassMark single-thread and Cinebench R23 single-core. The find prime numbers result also goes to Intel, suggesting its architecture handles that specific algorithm slightly better per thread.

The data suggests a clear use-case split. For rendering, compression, encryption, physics simulation, or any parallel compute task, the AMD processor delivers between 41.6% and 225.4% more performance. For lightly threaded applications where a single core does most of the work, Intel holds a small but consistent edge, never exceeding 8%.

However, the magnitude of the wins matters. AMD's smallest victory is 31.9%, while Intel's largest is 8%. Even in the workloads Intel wins, the margin is small enough that real-world perceptible differences would be minimal. In the workloads AMD wins, the margins are large enough to change the nature of the task, such as cutting compression time by more than half.

FAQ

Q: Which processor has a higher average benchmark score?

A: The AMD Ryzen 7 8700G has an average benchmark score of 33,089, while the Intel Core 5 315 averages 18,188. AMD also sits at the 83rd percentile of all CPUs, compared to Intel's 72nd percentile.

Q: How large is the gap in Cinebench R23 multicore?

A: AMD scores 17,128 against Intel's 12,981, a 31.9% advantage. That is AMD's smallest multicore win in the dataset, yet still substantial.

Q: Does the Intel Core 5 315 win any benchmark by a large margin?

The Verdict

The benchmark data points to a clear hierarchy. The AMD Ryzen 7 8700G outperforms the Intel Core 5 315 in 11 of 15 tests, with wins ranging from 31.9% to 225.4%. The Intel processor wins 4 tests, none by more than 8%. The average benchmark scores reinforce this: 33,089 for AMD versus 18,188 for Intel.

The architectural differences explain the results. AMD offers more cores, more threads, dual-channel memory with higher bandwidth, more PCIe lanes, and a desktop-class 65 W TDP. Intel offers a smaller 3 nm process, higher base clock efficiency per watt, and a mobile form factor at 15 W, but its single-channel memory and lack of multithreading cap its throughput.

For desktop users who need compute throughput, rendering performance, compression speed, or any parallel workload, the AMD Ryzen 7 8700G is the clear choice from the data. Its 83rd percentile standing and nearest rivals at the same average score, including the AMD Ryzen 7 7800X3D, place it in strong company.

For users constrained by power or form factor, the Intel Core 5 315 may fit a mobile chassis where 15 W and BGA packaging are required. Its single-thread performance is marginally better, but the 0.8% Cinebench R23 single-core lead and 2.3% PassMark single-thread lead are unlikely to offset the massive multicore deficit.

The data does not support a scenario where the Intel Core 5 315 competes with the AMD Ryzen 7 8700G on equal footing. The AMD processor wins the multicore tests by margins that range from large to enormous, and it also wins most single-thread tests. The only Intel wins are in narrow single-thread scenarios, and those margins are small. The verdict from the recorded benchmarks is unambiguous: the AMD Ryzen 7 8700G is the stronger processor in nearly every measurable workload.
