Intel Arc Pro B390 vs NVIDIA RTX 4000 SFF Ada Generation Comparison

Intel Arc Pro B390 and NVIDIA RTX 4000 SFF Ada Generation target different segments entirely, and the recorded data confirms that split. The RTX 4000 SFF Ada Generation holds a commanding lead in every measurable performance category, while the Arc Pro B390 functions as an integrated graphics solution with system-shared memory and no dedicated VRAM. The database shows the NVIDIA card at the 95th percentile among all GPUs, compared to the 50th percentile for the Intel part, a gap that reflects their distinct design goals.

Where Each One Wins

The NVIDIA RTX 4000 SFF Ada Generation wins in all recorded performance scenarios. Its Geekbench OpenCL score of 124812 and Vulkan score of 109364 place it far ahead of the Intel Arc Pro B390, which has no benchmark entries in the database. The Intel part, by contrast, offers a unique advantage in form factor: it is an IGP (integrated graphics processor) with no slot width, no power connectors, and system-shared memory, meaning it requires no separate card installation. The NVIDIA card is a dual-slot, 168 mm long, 69 mm high add-in board with four mini-DisplayPort 1.4a outputs, while the Intel solution's display outputs are portable device dependent.

For workloads that demand sustained compute throughput, the RTX 4000 SFF Ada Generation delivers 19.17 TFLOPS FP32 and 19.17 TFLOPS FP16 (1:1), whereas the Arc Pro B390 provides 7.680 TFLOPS FP32 and 15.36 TFLOPS FP16 (2:1). The NVIDIA card's texture rate of 299.5 GTexel/s and pixel rate of 99.84 GPixel/s dwarf the Intel part's 120.0 GTexel/s and 60.00 GPixel/s. The Intel Arc Pro B390 wins only in terms of integration and power simplicity: it has no power connectors and a TDP of 80 W, while the NVIDIA card also has no power connectors but carries a TDP of 70 W and a suggested PSU of 250 W.

Architecture Differences

The two GPUs come from fundamentally different architectural lineages. The Intel Arc Pro B390 uses the Panther Lake chip with Xe3-LPG architecture, fabricated on a 3 nm process at Intel's own foundry. The NVIDIA RTX 4000 SFF Ada Generation uses the AD104 chip with Ada Lovelace architecture, built on a 5 nm process at TSMC. The Intel part belongs to the Arc Graphics-WM (Panther Lake) generation, while the NVIDIA card is from the Workstation Ada generation.

Core configurations diverge sharply. The NVIDIA card packs 6144 shading units, 192 texture mapping units, 64 ROPs, 48 ray tracing cores, and 192 tensor cores. The Intel Arc Pro B390 offers 1536 shading units, 48 TMUs, 24 ROPs, and 12 ray tracing cores, with no tensor core count listed. Clock behavior also differs: the Intel part runs at a 300 MHz base and 2500 MHz boost, while the NVIDIA card uses a 720 MHz base and 1560 MHz boost. The NVIDIA design compensates for lower clocks with far more parallel hardware.

Memory architecture represents the most significant divergence. The RTX 4000 SFF Ada Generation has 20 GB of dedicated GDDR6 memory on a 160-bit bus, delivering 280.0 GB/s bandwidth. The Arc Pro B390 relies entirely on system-shared memory, with bus width and bandwidth listed as system dependent. This means the Intel part's memory performance cannot be quantified independently, while the NVIDIA card's 280.0 GB/s is a fixed, measured figure.

Transistor counts and die sizes further separate the products. The NVIDIA AD104 contains 35,800 million transistors on a 294 mm² die, yielding a transistor density of 121.8 million per square millimeter. The Intel chip's transistor count and die size are unknown in the database. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API feature coverage matches.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between these two products, but the available Geekbench scores for the NVIDIA card provide context. The RTX 4000 SFF Ada Generation scores 124812 in OpenCL and 109364 in Vulkan, averaging 117088 across those two tests. Its nearest rivals in the database include the NVIDIA GB10 at 117393 (0.3% higher), the AMD Radeon PRO W7700 at 118976 (1.6% higher), the NVIDIA Tesla V100 SXM2 16 GB at 114395 (2.4% lower), and the NVIDIA RTX A5500 Mobile at 113944 (2.8% lower). This places the RTX 4000 SFF Ada Generation in a competitive band where it trades blows with high-end workstation and mobile parts.

The Intel Arc Pro B390 has no recorded benchmark scores, so no direct numerical comparison is possible. Its 50th percentile ranking versus the NVIDIA card's 95th percentile indicates that the Intel part lands in the middle of the GPU performance distribution, while the NVIDIA card sits near the top. In raw compute terms, the NVIDIA card delivers roughly 2.5 times the FP32 throughput (19.17 TFLOPS versus 7.680 TFLOPS), 2.5 times the texture rate (299.5 GTexel/s versus 120.0 GTexel/s), and 1.66 times the pixel rate (99.84 GPixel/s versus 60.00 GPixel/s). The NVIDIA card also has 4 times the shading units (6144 versus 1536), 4 times the TMUs (192 versus 48), and 4 times the ray tracing cores (48 versus 12).

Clock speed differences complicate a simple clock-for-clock comparison. The Intel part boosts to 2500 MHz, which is 60% higher than the NVIDIA card's 1560 MHz boost. However, the NVIDIA card's massive core count advantage overwhelms this clock gap. The Intel part's higher boost clock helps mitigate its smaller core configuration, but the recorded data shows the NVIDIA card still produces far higher fill rates and compute throughput.

The Verdict

The data clearly separates these two products by intended use. The NVIDIA RTX 4000 SFF Ada Generation is a dedicated workstation GPU with 20 GB of GDDR6 memory, 280.0 GB/s bandwidth, and 19.17 TFLOPS FP32 performance. Its 95th percentile ranking and benchmark scores in the 109000-125000 range demonstrate it belongs in professional rendering, simulation, and AI workloads where sustained compute and large memory pools matter. The dual-slot form factor, 168 mm length, and 69 mm height make it suitable for compact workstations, while its 70 W TDP and no power connectors keep power demands modest.

The Intel Arc Pro B390, as an IGP with system-shared memory, targets portable devices and integrated systems where a discrete card is impossible. Its 80 W TDP, no power connectors, and no slot width reflect a design that shares power and memory with the host processor. The 50th percentile ranking and lack of benchmark scores indicate it serves basic graphics duties rather than demanding compute tasks. Its 2500 MHz boost clock and 15.36 TFLOPS FP16 (2:1) capability suggest it can handle lightweight acceleration, but the system-shared memory bandwidth cannot match a dedicated 280.0 GB/s GDDR6 solution.

Users requiring a compact, low-power discrete GPU for professional workloads should select the RTX 4000 SFF Ada Generation. Users constrained to integrated graphics in portable devices should rely on the Arc Pro B390, understanding that its performance ceiling sits far below the NVIDIA card. The release dates confirm this timeline: the NVIDIA card arrived on 2023-03-20, while the Intel part launched on 2026-01-26, with the Intel product succeeding HD Graphics-WM and the NVIDIA card succeeding Workstation Ampere and preceding Blackwell PRO W.
