AMD Ryzen Embedded 9900X3D vs Intel Core 5 315 Comparison

Where Each One Wins

The AMD Ryzen Embedded 9900X3D and Intel Core 5 315 occupy opposite ends of the computing spectrum, and the recorded data reflects that split clearly. The AMD part is a desktop-class 12-core, 24-thread processor built for sustained multi-threaded workloads, while the Intel part is a mobile-focused 6-core, 6-thread chip designed around efficiency and single-thread responsiveness.

The AMD Ryzen Embedded 9900X3D wins in scenarios that scale with core count and cache capacity. Its 128 MB of L3 cache and 24 threads give it a decisive advantage in rendering, scientific computing, and any workload that parallelizes across many cores. The Intel Core 5 315, by contrast, wins in power-constrained environments and in tasks that rely on burst performance from a single core. Its 15 W TDP against the AMD part's 120 W TDP means the Intel chip fits into thin-and-light mobile systems where thermals and battery life take priority over raw throughput.

The database's percentile ranking supports this split. The Intel Core 5 315 sits at the 72nd percentile of all CPUs, while the AMD Ryzen Embedded 9900X3D is listed at the 50th percentile. That difference reflects the Intel part's strong position in the mobile segment, where its combination of modest power draw and competitive single-thread results places it above many peers. The AMD chip, despite its heavier power envelope and larger core count, ranks lower relative to all CPUs because the desktop segment includes many high-core-count server and workstation parts.

The Intel Core 5 315 has an average benchmark score of 18,188, placing it directly alongside the AMD EPYC 9274F at 18,189 and the Intel Core i7-9700 at 18,180. The AMD Ryzen Embedded 9900X3D has an average benchmark score of 0 in the current database, meaning no aggregate result is available for comparison. The strengths of the AMD part must therefore be inferred from its specifications and the Intel part's benchmark breakdown.

Architecture Differences

The two processors come from different foundries and use different process nodes. The AMD Ryzen Embedded 9900X3D uses a 4 nm process from TSMC, while the Intel Core 5 315 uses a 3 nm process from Intel. The AMD chip is built on the Granite Ridge codename with Zen 5 architecture, part of the Ryzen Embedded generation. The Intel chip uses the Wildcat Lake codename with Core 5 branding.

Core counts differ sharply. The AMD part has 12 cores and 24 threads, enabling simultaneous multithreading across all cores. The Intel part has 6 cores and 6 threads with no hyper-threading, so each core handles exactly one thread. This difference alone explains why the AMD chip dominates heavily parallel workloads.

Clock speeds also diverge substantially. The AMD Ryzen Embedded 9900X3D has a base clock of 4.40 GHz and a boost clock of 5.50 GHz. The Intel Core 5 315 has a base clock of 1.50 GHz and a boost clock of 4.40 GHz. The AMD part's base clock is nearly three times higher, which matters for sustained workloads that cannot rely on boost behavior.

Cache hierarchies reflect different design philosophies. The AMD part provides 80 KB of L1 cache per core, 1 MB of L2 cache per core, and 128 MB of L3 cache. The Intel part has 192 KB of total L1 cache, 2.5 MB of L2 cache, and 6 MB of shared L3 cache. The AMD chip's 128 MB L3 cache is a defining feature, far exceeding the Intel part's 6 MB.

Memory support differs in both type and channel count. The AMD chip supports DDR5 memory over a dual-channel bus with 89.6 GB/s of bandwidth. The Intel chip supports DDR5 and LPDDR5X over a single-channel bus with 59.7 GB/s of bandwidth. The AMD part also supports ECC memory, while the Intel part does not.

PCIe connectivity favors the AMD chip with Gen 5 and 24 CPU lanes, versus Gen 4 with 6 CPU lanes for the Intel part. The AMD chip has an unlocked multiplier, while the Intel part is locked. The AMD chip uses AMD Socket AM5, while the Intel part uses Intel BGA 1516, a soldered mobile socket.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between these two processors, so the comparison relies on the Intel Core 5 315's individual benchmark scores and the AMD part's specification sheet. The Intel chip's recorded results provide the reference points.

In Cinebench R23, the Intel Core 5 315 scores 12,981 in multi-core and 1,832 in single-core. The multi-core result, achieved with only 6 threads, is respectable for a mobile chip. The single-core score indicates strong per-thread performance from the 4.40 GHz boost clock and the 3 nm Intel process.

Cinebench R20 shows 5,452 multi-core and 769 single-core for the Intel part. Cinebench R15 shows 1,308 multi-core and 184 single-core. These results track the expected scaling across the different benchmark versions.

The Passmark suite gives a fuller picture of the Intel chip's strengths. The multi-thread score is 15,272, while the single-thread score is 4,021. The data compression score is 146,143, which is the highest single result in the Intel chip's benchmark list. Data encryption scores 11,119, and extended instructions score 13,143. Floating point math reaches 42,441, while integer math reaches 31,690. Random string sorting scores 17,551, and physics scores 1,163. The prime number search score is 112.

The AMD Ryzen Embedded 9900X3D has no benchmark scores in the database. Its 12 cores and 24 threads would theoretically place it well above the Intel part in any multi-threaded test, but the database does not record such results. The Intel part's nearest rivals include the AMD EPYC 9274F with an average score of 18,189 and a 0% delta, the Intel Core i7-9700 at 18,180 with a 0% delta, the Intel Core i7-1365U at 18,177 with a 0.1% delta, and the AMD Ryzen 7 5700U at 18,176 with a 0.1% delta. The Intel Core 5 315's average score of 18,188 puts it within 0.1% of these competitors, showing that it performs on par with established desktop and mobile processors from previous generations.
