AMD Ryzen 9 9850HX vs Intel Core 5 315 Comparison

The AMD Ryzen 9 9850HX and the Intel Core 5 315 occupy different tiers of the mobile processor market, and the recorded benchmark data reflects a substantial performance gap. The Ryzen 9 9850HX, a 12-core Zen 5 part, dominates the PassMark suite, winning all 11 head-to-head comparisons. The Intel Core 5 315, a 6-core Wildcat Lake chip, trails significantly in raw throughput but offers its own advantages in platform efficiency and integrated graphics. This analysis breaks down the measured performance, architectural differences, and the specific use cases each processor serves based solely on the database figures.

Where Each One Wins

The head-to-head benchmark results show a clear sweep: the AMD Ryzen 9 9850HX wins every single recorded comparison. The largest margins come in compute-heavy workloads. In passmark_integer_math, the Ryzen 9 scores 172,943 against Intel's 31,690, a delta of 445.7%. Data compression follows closely, with AMD at 662,381 versus 146,143, a 353.2% advantage. Extended instructions show a 309.5% lead (53,817 vs. 13,143), and random string sorting shows a 299.8% lead (70,175 vs. 17,551). These are not marginal wins; the Ryzen 9 delivers between three and five times the throughput in these specific tests.

The gap narrows considerably in single-threaded performance. The passmark_single_thread test records 4,461 for the AMD part and 4,021 for the Intel part, a delta of only 10.9%. This indicates that while the Ryzen 9 holds the single-thread crown, the Intel Core 5 315 is competitive in lightly threaded tasks, making it a more reasonable option for everyday responsiveness where multi-core scaling is limited.

The Intel Core 5 315 does have a separate set of Cinebench results in the database, which the AMD chip lacks. Its strengths there are relative to its own class, not against the Ryzen 9. The data shows a Cinebench R23 multi-core score of 12,981 and a single-core score of 1,832. These figures position the Intel part as a capable mainstream mobile processor, but the absence of comparable AMD Cinebench data prevents a direct cross-reference. The overall percentile ranking reinforces the hierarchy: the Ryzen 9 9850HX sits at the 97th percentile of all CPUs, while the Core 5 315 sits at the 72nd.

Architecture Differences

The two processors are built on fundamentally different designs. The AMD Ryzen 9 9850HX uses the Zen 5 architecture, codenamed Fire Range, fabricated on a 4 nm TSMC process. It contains 12 cores and 24 threads, with a base clock of 3.00 GHz and a boost clock of 5.20 GHz. The thermal design power is 55 W. The chip packages 16,630 million transistors across a dual-chip die configuration, with each die measuring 70.6 mm². Cache is organized per core: 80 KB of L1 and 1 MB of L2 per core, with a shared 64 MB L3 pool. Memory support includes DDR5 over a dual-channel bus, providing a bandwidth of 89.6 GB/s. ECC memory is supported. PCIe connectivity is Gen 5 with 28 lanes from the CPU. The integrated graphics are Radeon 610M. The multiplier is unlocked, and the socket is AMD Socket FL1.

The Intel Core 5 315 uses the Wildcat Lake codename, built on a 3 nm Intel process. It has 6 cores and 6 threads, meaning no simultaneous multithreading. Base clock is 1.50 GHz, boost clock is 4.40 GHz, and the TDP is 15 W. The cache layout is simpler: 192 KB of L1, 2.5 MB of L2, and 6 MB of shared L3. Memory support covers DDR5 and LPDDR5X, but the bus is single-channel, capping bandwidth at 59.7 GB/s. ECC memory is not supported. PCIe is Gen 4 with 6 lanes from the CPU. The integrated graphics are Intel Xe3 Graphics with 2 Xe cores. The multiplier is locked, and the socket is Intel BGA 1516.

The process node difference is notable: Intel's 3 nm versus TSMC's 4 nm. The Intel part also carries a much lower 15 W TDP compared to the 55 W AMD part, which suggests a very different thermal envelope and power draw profile. The AMD chip compensates with more cores, more threads, a higher boost clock, and roughly triple the L3 cache. The Intel part compensates with a newer process node and a more efficient power target, plus a wider memory type selection (LPDDR5X support).

The Verdict

The recorded data indicates two distinct market positions. The AMD Ryzen 9 9850HX is the clear performance leader across every measured PassMark test. For workloads that scale with core count and thread count, such as integer math, data compression, and multi-threaded rendering, the Ryzen 9 delivers overwhelming advantages, often exceeding 200% to 400% over the Intel part. Its 97th percentile ranking places it among the top processors in the database, with nearest rivals like the Intel Xeon w7-3555 (0.2% delta) and the Intel Xeon w7-2595X (2.1% delta) confirming its position in high-end workstation territory.

The Intel Core 5 315 is not designed to compete in that class. Its 72nd percentile ranking and nearest rivals, including the Intel Core i7-9700 and the AMD Ryzen 7 5700U with 0.0% and 0.1% deltas respectively, place it in the mainstream mobile segment. Its 15 W TDP and single-channel memory bus indicate a focus on power efficiency rather than peak performance. The single-thread gap of 10.9% shows that for basic tasks, the Core 5 315 is not far behind, making it a reasonable choice for thin-and-light notebooks where battery life and thermals take priority over multi-core muscle.

The choice between these two processors depends entirely on the workload profile. The data shows no scenario in which the Intel part wins a benchmark, so the Ryzen 9 9850HX is the only option for maximum compute performance. The Intel Core 5 315 is the only option for minimal power draw, as its 15 W TDP is less than a third of the AMD chip's 55 W TDP. The launch MSRP of the Intel part is $340, which can be stated as a reference point, but the database does not provide a launch MSRP for the AMD chip.

Head-to-Head Benchmarks

The most decisive victory for the AMD Ryzen 9 9850HX comes in passmark_integer_math, where it scores 172,943 against 31,690, a 445.7% advantage. This is the largest percentage delta in the entire head-to-head set. Data compression is the next biggest, with the AMD chip at 662,381 versus 146,143, a 353.2% lead. Extended instructions show a 309.5% margin (53,817 vs. 13,143), and random string sorting shows a 299.8% margin (70,175 vs. 17,551). These four tests all involve heavy data manipulation or algorithmic throughput, and the AMD chip's larger core count, higher clocks, and larger cache all contribute to the result.

In passmark_multithread, the Ryzen 9 scores 51,722, which is 238.7% ahead of the Intel part's 15,272. This test is a direct measure of parallel execution capability, and the 12-core/24-thread AMD design crushes the 6-core/6-thread Intel design. Data encryption shows a 189% lead (32,139 vs. 11,119), and prime number finding shows a 188.4% lead (323 vs. 112). Floating point math is 171.1% ahead (115,062 vs. 42,441), and physics is 162.6% ahead (3,054 vs. 1,163). All of these tests favor the AMD chip by margins exceeding 150%.

The narrowest win for the AMD Ryzen 9 9850HX is in passmark_single_thread, where it scores 4,461 versus 4,021, a 10.9% delta. This is the only test where the gap is under 100%, and it indicates that the Intel Core 5 315's single-core performance, driven by its 4.40 GHz boost clock, is within striking distance of the AMD chip's 5.20 GHz boost. The passmark_singlethread result is identical, confirming the same 10.9% margin. Across all 11 head-to-head benchmarks, the AMD Ryzen 9 9850HX records 11 wins and 0 losses, with an average benchmark score of 106,413 compared to the Intel Core 5 315's 18,188. The overall performance class difference is substantial, and the data provides no evidence of any workload category where the Intel part can outpace the AMD chip.
