AMD Ryzen Embedded 9900X3D vs Intel Processor 300 Comparison

Head-to-Head Benchmarks

The recorded database contains no benchmark scores for either the AMD Ryzen Embedded 9900X3D or the Intel Processor 300. With zero benchmark entries and zero wins recorded for either processor, the head-to-head comparison relies entirely on architectural and specification data rather than measured performance results. Both parts sit at the 50th percentile among all CPUs in the database, though this figure reflects their placement based on available data, not actual workload testing.

The AMD Ryzen Embedded 9900X3D presents a 12-core, 24-thread configuration with a base clock of 4.40 GHz and a boost clock of 5.50 GHz. The Intel Processor 300 offers 2 cores and 4 threads, with a base clock of 3.90 GHz and no listed boost clock. The core count delta is substantial: the AMD part delivers 6 times the cores and 6 times the threads of the Intel part. This translates directly into parallel workload capability, where the Ryzen Embedded 9900X3D can process significantly more simultaneous threads.

The L3 cache difference is decisive. The AMD processor carries 128 MB of L3 cache, while the Intel Processor 300 has 6 MB shared. That is a 21.3x advantage in last-level cache capacity for the AMD part. The Ryzen Embedded 9900X3D also includes 80 KB of L1 cache per core and 1 MB of L2 cache per core, while the Intel Processor 300 has the same 80 KB L1 per core but 1.25 MB of L2 per core, giving Intel a slight edge in per-core L2. However, the aggregate cache hierarchy strongly favors AMD.

Memory bandwidth further separates the two. The AMD processor lists 89.6 GB/s of memory bandwidth, a figure the Intel part does not report at all. Both support dual-channel memory, but the AMD part is limited to DDR5, whereas the Intel Processor 300 supports both DDR4 and DDR5. That flexibility on the Intel side is a practical advantage for system builders with existing DDR4 modules, but it does not compensate for the bandwidth shortfall in raw throughput.

The thermal design power (TDP) values show a wide gap: 120 watts for the AMD Ryzen Embedded 9900X3D versus 46 watts for the Intel Processor 300. The AMD part draws 2.6x more power, reflecting its larger core count and higher clock speeds. The Intel part, with its modest 46-watt envelope, fits into low-power and compact builds where heat dissipation is a primary concern.

A: The launch MSRP is $82.

The Verdict

The data indicates two processors with fundamentally different target use cases. The AMD Ryzen Embedded 9900X3D is built for heavy parallel workloads: 12 cores, 24 threads, 128 MB of L3 cache, and 89.6 GB/s of memory bandwidth. Its 5.50 GHz boost clock and unlocked multiplier suggest headroom for overclocking, and its ECC memory support points toward reliability-sensitive applications such as servers or embedded systems requiring data integrity.

The Intel Processor 300 is a low-power, entry-level desktop part. Its 2 cores and 4 threads handle basic tasks, its 46-watt TDP suits compact or passively cooled systems, and its support for both DDR4 and DDR5 offers memory flexibility. The unlocked multiplier is absent, meaning no overclocking, and the lack of ECC memory restricts its use in error-checking environments.

Benchmark results are absent, so the verdict rests on specification analysis. For multi-threaded, cache-heavy, or memory-bandwidth-intensive workloads, the AMD Ryzen Embedded 9900X3D is the clear choice based on its core count, cache size, and bandwidth figures. For low-power, simple desktop tasks where cost and thermal footprint matter, the Intel Processor 300 is the appropriate option, especially given its $82 launch MSRP. The database shows no recorded wins for either part, so the decision falls to workload requirements rather than measured performance.

Specification Differences

The two processors differ across nearly every specification field. The AMD Ryzen Embedded 9900X3D uses 12 cores and 24 threads, while the Intel Processor 300 uses 2 cores and 4 threads. The AMD base clock is 4.40 GHz versus 3.90 GHz for Intel, and the AMD boost clock is 5.50 GHz, with no boost clock listed for Intel. TDP is 120 watts for AMD versus 46 watts for Intel.

Socket compatibility diverges: AMD uses Socket AM5, while Intel uses Socket 1700. The AMD part has an unlocked multiplier, the Intel part does not. ECC memory is supported on the AMD processor but not on the Intel processor. Memory support differs: AMD only supports DDR5, while Intel supports both DDR4 and DDR5. Memory bandwidth is listed at 89.6 GB/s for AMD, with no figure for Intel.

PCIe lanes also differ: the AMD Ryzen Embedded 9900X3D provides Gen 5 with 24 lanes (CPU only), while the Intel Processor 300 provides Gen 5 with 16 lanes (CPU only). Integrated graphics differ as well: AMD includes Radeon Graphics, Intel includes UHD Graphics 710. The release dates show the AMD part launched on 2025-10-06, while the Intel part launched on 2024-01-07. The part numbers are distinct: 100-000001368E for AMD and SRN3J for Intel.

Architecture Differences

The AMD Ryzen Embedded 9900X3D belongs to the 9000 series and uses the Granite Ridge codename, part of the Ryzen Embedded line built on Zen 5 (Granite Ridge) generation. It is manufactured on a 4 nm process by TSMC, with 16,630 million transistors and a die size of 2x 70.6 mm². The Intel Processor 300 uses the Raptor Lake architecture with the Raptor Lake-S codename, part of the Intel Processor (Raptor Lake) generation. It is manufactured on a 10 nm process by Intel, with a die size of 163 mm²; transistor count is not listed.

Cache architecture differs in structure. The AMD processor has 80 KB of L1 cache per core, 1 MB of L2 cache per core, and 128 MB of L3 cache. The Intel processor has 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and 6 MB of shared L3 cache. The AMD L3 cache is over 20 times larger, which benefits workloads with large working sets that repeatedly access the same data.

The process node difference is notable: 4 nm for AMD against 10 nm for Intel. This implies a denser transistor layout for AMD, which aligns with its higher core count and smaller total die area despite a much larger transistor count. The AMD part uses two separate 70.6 mm² dies, while the Intel part uses a single 163 mm² die. The dual-die design for AMD likely facilitates the large L3 cache, while the monolithic Intel die keeps power and complexity lower.

The AMD processor is marked as Active in production status, as is the Intel processor. Both target the desktop market segment. The AMD processor has an unlocked multiplier for overclocking, while the Intel processor is locked. The AMD processor supports ECC memory and includes Radeon Graphics, while the Intel processor lacks ECC support and includes UHD Graphics 710. The AMD part also has more PCIe lanes (24 versus 16), which supports additional expansion devices such as GPUs, NVMe drives, or network cards.
