AMD Ryzen 7 9850X3D vs Intel Core 5 315 Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive sweep: the AMD Ryzen 7 9850X3D wins all 15 shared benchmark comparisons against the Intel Core 5 315. No test favors the Intel part. The margins, however, vary widely, revealing where each architecture's strengths and weaknesses lie.

The largest gaps appear in compute-heavy and integer workloads. In PassMark integer math, the AMD part scores 123,140 against Intel's 31,690, a delta of 288.6%. Prime number finding shows a similar story: 435 versus 112, a 288.4% advantage. These are the kind of workloads that scale with core count, thread count, and raw throughput, and the AMD chip holds massive leads there.

Data compression is another blowout. The Ryzen 7 9850X3D records 474,501 in PassMark data compression, while the Core 5 315 manages 146,143. That is a 224.7% difference. Extended instructions follow at 198.8% (39,272 versus 13,143). Floating point math is comparatively closer but still lopsided: 81,998 versus 42,441, a 93.2% gap. Physics simulation shows 4,171 against 1,163, a 258.6% delta.

Multithreaded rendering tests reinforce the pattern. In Cinebench R15 multicore, the AMD processor scores 3,551 to Intel's 1,308, a 171.5% lead. Cinebench R23 multicore shows 22,807 versus 12,981, a 75.7% gap. PassMark multithread lands at 41,318 versus 15,272, a 170.5% difference. Random string sorting, often sensitive to memory subsystem behavior, shows 49,764 against 17,551, a 183.5% delta.

Single-thread results narrow the divide considerably. Cinebench R15 single-core has the AMD chip at 343 versus 184, an 86.4% lead. Cinebench R23 single-core shows 2,228 versus 1,832, a 21.6% gap. PassMark single-thread records 4,704 versus 4,021, a 17% difference. Data encryption shows 22,856 versus 11,119, a 105.6% lead. These single-thread numbers indicate that the Intel part is not outclassed in basic clock-for-clock efficiency, but it simply cannot overcome the AMD chip's higher boost clock and larger core complement.

The overall average benchmark score for the AMD Ryzen 7 9850X3D is 58,386, placing it in the 92nd percentile of all CPUs in the database. Its nearest rivals include the Intel Xeon Platinum 8260M (58,323, delta of 0.1%), the Intel Xeon w5-2545 (58,504, delta of -0.2%), the Intel Core i9-14900 (58,115, delta of 0.5%), and the AMD Ryzen AI 9 HX 470 (58,826, delta of -0.7%). That puts it in a tight cluster of high-end desktop and workstation parts, within 1% of all four neighbors.

The Intel Core 5 315, by contrast, has an average benchmark score of 18,188, placing it in the 72nd percentile. Its nearest rivals are the AMD EPYC 9274F (18,189, delta of 0%), the Intel Core i7-9700 (18,180, delta of 0%), the Intel Core i7-1365U (18,177, delta of 0.1%), and the AMD Ryzen 7 5700U (18,176, delta of 0.1%). It sits in a much lower performance tier, roughly one-third the average score of the AMD part.

The Verdict

The data is unambiguous. The AMD Ryzen 7 9850X3D outperforms the Intel Core 5 315 in every recorded benchmark, with deltas ranging from 17% in single-threaded PassMark tests to nearly 289% in integer math. The AMD chip is a desktop processor with 8 cores, 16 threads, a 5.60 GHz boost clock, and a 96 MB shared L3 cache. The Intel part is a mobile processor with 6 cores, 6 threads, a 4.40 GHz boost clock, and a 6 MB shared L3 cache. Those specification differences explain the performance gap almost entirely.

For workloads that scale with thread count, such as Cinebench R23 multicore, PassMark multithread, data compression, and integer math, the AMD Ryzen 7 9850X3D is the clear choice. Its 16 threads and 96 MB L3 cache give it a massive advantage over the Intel Core 5 315's 6 threads and 6 MB L3. Even in single-threaded tests, where the Intel part's 3 nm process and higher per-core efficiency might be expected to help, the AMD chip still leads by 17% to 86%, depending on the test.

The Intel Core 5 315 is a low-power mobile chip with a 15 W TDP and a single-channel memory bus. Its performance profile places it alongside older desktop parts like the Intel Core i7-9700 and mobile parts like the Intel Core i7-1365U, all within 0.1% of its average score. It is not designed to compete with the Ryzen 7 9850X3D, and the benchmark data confirms that.

Who should pick which? The AMD Ryzen 7 9850X3D suits desktop users who need maximum multi-threaded throughput, large cache capacity, and the highest available single-thread scores in this comparison. The Intel Core 5 315 suits compact, low-power mobile systems where the 15 W TDP and integrated Intel Xe3 Graphics are more relevant than raw benchmark dominance.
