AMD Radeon AI PRO 9600D vs Intel Arc Pro B390 Comparison

The Verdict

The AMD Radeon AI PRO 9600D and Intel Arc Pro B390 occupy fundamentally different positions in the hardware landscape. The database shows the AMD part as a discrete, single-slot PCIe 5.0 x16 card with 32 GB of dedicated GDDR6 memory, 3,072 shading units, and a 150 W TDP. The Intel part is an integrated graphics processor (IGP) with system-shared memory, 1,536 shading units, and an 80 W TDP. These are not direct competitors in the traditional sense; they serve distinct form factors and workloads. The AMD Radeon AI PRO 9600D is the choice for systems requiring a dedicated, high-throughput GPU with substantial local memory and a wide 256-bit memory bus. The Intel Arc Pro B390 is the choice for compact, low-power, portable devices where an integrated solution with no additional power connectors is mandatory. The data indicates the AMD card delivers roughly 3.2 times the FP32 compute throughput of the Intel part (24.82 TFLOPS versus 7.680 TFLOPS) and more than three times the texture rate (387.8 GTexel/s versus 120.0 GTexel/s). For any workload that stresses raw shader throughput or memory bandwidth, the discrete AMD card is the clear pick. For ultra-portable or embedded designs where power draw and physical space are the primary constraints, the Intel IGP is the only viable option between the two.

Architecture Differences

The AMD Radeon AI PRO 9600D is built on the RDNA 4.0 architecture using the Navi 48 chip, fabricated on a 4 nm process at TSMC. The Intel Arc Pro B390 uses the Xe3-LPG architecture with the Panther Lake chip, fabricated on a 3 nm process at Intel. The process node difference (4 nm versus 3 nm) is notable, though the Intel part's transistor density is not recorded.

The AMD chip integrates 48 ray tracing cores, whereas the Intel chip integrates 12. The AMD GPU has 192 texture mapping units and 96 ROPs, while the Intel GPU has 48 TMUs and 24 ROPs. The shading unit counts differ significantly: 3,072 on the AMD part versus 1,536 on the Intel part.

The AMD Radeon AI PRO 9600D computes FP16 at a 1:1 ratio with FP32, delivering 24.82 TFLOPS for both. The Intel Arc Pro B390 computes FP16 at a 2:1 ratio, delivering 15.36 TFLOPS FP16 versus 7.680 TFLOPS FP32. This architectural difference indicates the Intel part has dedicated FP16 throughput that doubles its FP32 rate, while the AMD part maintains equal throughput across both precisions.

The AMD card is a discrete solution with PCIe 5.0 x16 bus interface and a single DisplayPort 2.1a output. The Intel part is an IGP with a "Portable Device Dependent" display output and no dedicated bus interface beyond the integrated graphics path.

Specification Differences

The two GPUs differ across nearly every recorded specification field. The AMD Radeon AI PRO 9600D has a base clock of 1080 MHz and a game clock of 1080 MHz, while the Intel Arc Pro B390 has a base clock of 300 MHz and no recorded game clock. The boost clocks are 2020 MHz for AMD and 2500 MHz for Intel.

Memory specifications are fundamentally different. The AMD card uses 32 GB of GDDR6 with a 256-bit bus and 576.0 GB/s bandwidth, running at 2250 MHz (18 Gbps effective). The Intel IGP uses system-shared memory with a system-dependent bus width and bandwidth.

Compute resources show a wide gap. The AMD card has 3,072 shading units, 192 TMUs, 96 ROPs, and 48 RT cores. The Intel IGP has 1,536 shading units, 48 TMUs, 24 ROPs, and 12 RT cores. Pixel rate is 193.9 GPixel/s for AMD versus 60.00 GPixel/s for Intel. Texture rate is 387.8 GTexel/s for AMD versus 120.0 GTexel/s for Intel. FP32 throughput is 24.82 TFLOPS for AMD versus 7.680 TFLOPS for Intel.

Power and physical specifications differ sharply. The AMD card has a 150 W TDP, a single-slot form factor, a 1x 16-pin power connector, and a 450 W suggested PSU. The Intel IGP has an 80 W TDP, no power connectors, no suggested PSU, and an IGP slot width. The AMD card measures 241 mm by 111 mm by 19 mm. The Intel part has no recorded dimensions.

Both GPUs share the same API support: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both are listed as Active production status. The AMD card's predecessor is the Radeon Pro Vega, while the Intel part's predecessor is the HD Graphics-WM. The AMD card released on 2025-12-10, and the Intel part released on 2026-01-26.

Head-to-Head Benchmarks

The recorded head-to-head benchmark data contains no entries, and both GPUs have an average benchmark score of zero. However, the specification differences allow for direct computational comparisons based on the documented rates.

The most significant win for the AMD Radeon AI PRO 9600D is in FP32 throughput. The AMD card delivers 24.82 TFLOPS, which is 3.23 times the Intel Arc Pro B390's 7.680 TFLOPS. This translates to a 223% advantage in raw single-precision compute. For FP16 workloads, the AMD card delivers 24.82 TFLOPS, while the Intel part delivers 15.36 TFLOPS, giving AMD a 61.6% lead in that precision.

Texture throughput heavily favors the AMD card. The AMD GPU achieves 387.8 GTexel/s versus 120.0 GTexel/s for the Intel GPU, a 3.23x advantage. This indicates a substantial lead in texturing-heavy workloads such as traditional rasterization with complex material sampling.

Pixel fill rate also favors AMD, with 193.9 GPixel/s versus 60.00 GPixel/s. This 3.23x ratio mirrors the texture rate advantage, confirming that the AMD card's additional TMUs and ROPs scale its output rates proportionally.

Memory bandwidth is a decisive differentiator. The AMD card provides 576.0 GB/s of dedicated GDDR6 bandwidth, while the Intel IGP's bandwidth is system-dependent and not quantified in the database. For workloads that saturate memory, the AMD card's dedicated 256-bit bus provides a fixed, high-bandwidth path that the shared-memory Intel solution cannot match.

The Intel Arc Pro B390 does hold advantages in specific areas. Its boost clock of 2500 MHz exceeds the AMD card's 2020 MHz by 23.8%. Its FP16 to FP32 ratio of 2:1 indicates that the Intel architecture can double its FP32 rate when operating in FP16 mode, a feature the AMD card does not offer (1:1 ratio). The Intel part also consumes 80 W versus 150 W for the AMD card, a 46.7% reduction in TDP, making it more suitable for thermally constrained environments.

The transistor and die size data are incomplete for the Intel part, but the AMD card's 53,900 million transistors on a 357 mm² die yield a density of 151.0M transistors per mm². The Intel 3 nm process node is smaller than the AMD 4 nm node, but without die size data, direct density comparisons are not possible.

Both GPUs share identical API support, meaning software feature levels do not differentiate them. The AMD card's PCIe 5.0 x16 interface provides a high-bandwidth host connection, while the Intel IGP's bandwidth is determined by the host system's shared memory architecture.

In the absence of recorded benchmark scores, the specification-derived rates indicate the AMD Radeon AI PRO 9600D dominates in raw throughput metrics, while the Intel Arc Pro B390 offers higher clock speeds, lower power consumption, and a 2:1 FP16 advantage. The choice between them depends entirely on the target platform: discrete expansion slot versus integrated portable device.
