AMD Ryzen Embedded 9900X3D vs Intel Arc G3 Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark results for the AMD Ryzen Embedded 9900X3D and the Intel Arc G3. Neither processor has an average benchmark score, and the wins counters show zero for both parts. The percentile versus all CPUs is identical for both, each sitting at the 50th percentile in the database. Without measured scores, the comparison must rely entirely on the specification and architectural data recorded for each unit.

The AMD Ryzen Embedded 9900X3D carries a boost clock of 5.50 GHz against the Intel Arc G3's 4.60 GHz. That 0.90 GHz difference in maximum frequency favors the AMD part for single-thread burst workloads, assuming IPC parity, which the database does not measure directly. The base clocks differ more substantially: 4.40 GHz for the AMD versus 1.90 GHz for the Intel. The AMD part's base clock is more than double the Intel part's base clock, indicating that sustained all-core workloads at stock settings will run at significantly higher frequency on the AMD chip.

The Intel Arc G3 counters with a higher memory bandwidth figure. The database records 136.5 GB/s for the Intel part against 89.6 GB/s for the AMD part. That 46.9 GB/s advantage gives the Intel chip a meaningful edge in memory-bound operations such as large data streaming, certain database workloads, and tasks that saturate memory channels.

Thread counts diverge sharply. The AMD Ryzen Embedded 9900X3D provides 12 cores and 24 threads, while the Intel Arc G3 provides 14 cores and 14 threads. The AMD part has 10 more threads, a 71.4% thread advantage. However, the Intel part has 2 more physical cores. For workloads that scale with physical core count and do not benefit from simultaneous multithreading, the Intel chip holds a modest core-count lead. For workloads that scale with thread count, the AMD chip holds a commanding lead.

Thermal design power differs by a factor of nearly five. The AMD part is rated at 120 W, while the Intel Arc G3 is rated at 25 W. That 95 W gap means the Intel part consumes far less power under load. The database does not record measured power draw, but the TDP figures indicate the Intel chip fits into thermal envelopes where the AMD part cannot operate.

Where Each One Wins

The AMD Ryzen Embedded 9900X3D wins in scenarios that demand high per-thread performance and heavy multi-threading. Its 5.50 GHz boost clock and 4.40 GHz base clock provide strong frequency headroom. Its 24 threads handle parallel workloads that can utilize simultaneous multithreading. The 128 MB L3 cache, which the database records for the AMD part, gives it a large temporary storage area for working sets that fit within that capacity, reducing repeated memory accesses. The AMD part also supports ECC memory, which matters for data integrity in embedded and server-adjacent deployments.

The Intel Arc G3 wins in scenarios constrained by power and physical space. Its 25 W TDP allows operation in fanless or low-power designs where a 120 W part would require substantial cooling. Its 136.5 GB/s memory bandwidth exceeds the AMD part's 89.6 GB/s, giving it an advantage in workloads that stream large datasets through memory. The Intel part also has 2 more physical cores, which benefits workloads that scale with core count and do not benefit from extra threads per core. The Intel chip's 4-lane PCIe Gen 5 connection, while narrower than the AMD part's 24 lanes, suits compact mobile or embedded systems with limited expansion needs.

The AMD part uses the AMD Socket AM5, a standard desktop socket, and has an unlocked multiplier. The Intel part uses Intel BGA 2540, a soldered mobile socket, and has a locked multiplier. The AMD chip targets desktop and embedded systems where the user can swap processors, while the Intel chip targets integrated mobile platforms where the CPU is permanently attached. The AMD part's 24 PCIe Gen 5 lanes allow multiple high-speed devices, while the Intel part's 4 lanes limit expansion to a single fast device or a few slower ones.

Architecture Differences

The two processors come from different manufacturers and use different process nodes. The AMD Ryzen Embedded 9900X3D uses a 4 nm process from TSMC. The Intel Arc G3 uses a 3 nm process from Intel. The Intel node is one step smaller in the process generation naming, but the database provides no transistor density or performance-per-watt measurements, so no direct efficiency conclusion can be drawn from the node alone.

The AMD part codenames as Granite Ridge and belongs to the Ryzen Embedded generation built on Zen 5. The Intel part codenames as Panther Lake and belongs to the Arc G3 generation. These are entirely separate microarchitectures with no shared design lineage.

The AMD part uses a dual-chiplet design. The database records a die size of 2x 70.6 mm², indicating two separate silicon dies. The transistor count is recorded as 16,630 million for the AMD part. The Intel part has no die size or transistor count recorded in the database, so a direct comparison of silicon area and transistor budget is not possible.

Cache hierarchies differ in structure and capacity. The AMD part has 80 KB of L1 cache per core and 1 MB of L2 cache per core. The Intel part has 192 KB of L1 cache per core and 2.5 MB of L2 cache per core. Per core, the Intel part has more than double the L1 cache and 2.5 times the L2 cache. The AMD part has 128 MB of L3 cache, while the Intel part has 18 MB of shared L3 cache. The AMD part's L3 cache is more than seven times larger than the Intel part's L3 cache. The database does not record a 3D V-Cache designation for either part, so the AMD L3 advantage comes from its standard cache configuration.

The AMD part supports DDR5 memory in a dual-channel configuration. The Intel part supports LPDDR5X memory in a dual-channel configuration. LPDDR5X is a low-power memory standard typically used in mobile devices, while DDR5 is a standard desktop and server memory type. The Intel part's higher recorded memory bandwidth of 136.5 GB/s comes with the LPDDR5X interface, while the AMD part's 89.6 GB/s comes with the DDR5 interface.

The AMD part includes Radeon Graphics as integrated graphics. The Intel part includes Arc B370 as integrated graphics. Both parts have on-die or on-package graphics, but the database records no graphics performance measurements.
