Intel Arc Pro B390 vs NVIDIA RTX 4000 Ada Generation Comparison

Head-to-Head Benchmarks

The benchmark data available for this comparison is one-sided. The Intel Arc Pro B390 has no recorded benchmark scores in the database, while the NVIDIA RTX 4000 Ada Generation has two entries. The RTX 4000 Ada Generation scores 146593 in Geekbench OpenCL and 123842 in Geekbench Vulkan. Its average benchmark score sits at 135218, placing it in the 95th percentile of all GPUs in the database.

Without any recorded scores for the Arc Pro B390, a direct numerical comparison is impossible. The RTX 4000 Ada Generation’s nearest rivals provide context for its standing. The NVIDIA A10M averages 135230, a delta of 0 percent. The AMD Radeon PRO W6800 averages 135396, a delta of -0.1 percent. The AMD Radeon Pro W6800X Duo averages 135774, a delta of -0.4 percent. The AMD Radeon PRO V620 averages 136472, a delta of -0.9 percent. The RTX 4000 Ada Generation trails the V620 by 0.9 percent and sits essentially level with the A10M and W6800.

The Intel Arc Pro B390 holds a 50th percentile ranking among all GPUs, while the RTX 4000 Ada Generation holds the 95th. This percentile gap indicates a significant gulf in expected performance, though it derives from the absence of measured data for the Intel part. The RTX 4000 Ada Generation’s recorded scores show strong OpenCL and Vulkan results, with the OpenCL figure exceeding the Vulkan figure by 22751 points.

Architecture Differences

The two GPUs come from different architectural lineages. The Intel Arc Pro B390 uses the Panther Lake chip with Xe3-LPG architecture, part of the Arc Graphics-WM generation. It is built on a 3 nm process at Intel’s foundry. The NVIDIA RTX 4000 Ada Generation uses the AD104 chip with Ada Lovelace architecture, part of the Workstation Ada generation. It is built on a 5 nm process at TSMC.

The RTX 4000 Ada Generation has 35,800 million transistors on a 294 mm² die, giving a transistor density of 121.8M per mm². The Intel part lists unknown transistor count and die size. Process node differences suggest the Intel chip uses a more advanced manufacturing process, but the NVIDIA chip carries a massive transistor budget.

Compute resources differ substantially. The Intel Arc Pro B390 has 1536 shading units, 48 texture mapping units, and 24 raster output pipelines. The RTX 4000 Ada Generation has 6144 shading units, 192 TMUs, and 64 ROPs. That is four times the shading units, four times the TMUs, and over 2.5 times the ROPs.

Ray tracing hardware also diverges. The Intel part has 12 ray tracing cores. The NVIDIA part has 48 RT cores and 192 tensor cores. The Intel part lists no tensor core count. The RTX 4000 Ada Generation’s tensor cores support AI workloads, a feature absent from the Arc Pro B390’s listed specifications.

Clock behavior differs. The Intel GPU runs at a 300 MHz base and 2500 MHz boost. The NVIDIA GPU runs at a 1500 MHz base and 2175 MHz boost. The Intel part boosts higher, but its much lower base clock and far fewer execution units limit its peak throughput.

Memory architecture is fundamentally different. The Intel Arc Pro B390 uses system shared memory with a system dependent bus width and bandwidth. The RTX 4000 Ada Generation has 20 GB of dedicated GDDR6 memory on a 160-bit bus, delivering 360.0 GB/s bandwidth. The NVIDIA memory clock is listed as 2250 MHz with 18 Gbps effective. The Intel part’s memory performance depends entirely on the host system.

Power and physical design differ as well. The Intel Arc Pro B390 is an integrated graphics processor with an 80 W TDP, occupying the IGP slot width with no power connectors. The RTX 4000 Ada Generation is a single-slot card with a 130 W TDP, a 1x 16-pin power connector, and a suggested PSU of 300 W. Its dimensions are 245 mm in length and 112 mm in height.

Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX 4000 Ada Generation outputs 4x DisplayPort 1.4a. The Intel part’s display outputs are portable device dependent.

The Verdict

The recorded data favors the NVIDIA RTX 4000 Ada Generation overwhelmingly. It has measured benchmark scores, a 95th percentile ranking, and an average score of 135218. The Intel Arc Pro B390 has no recorded scores and sits at the 50th percentile. For any workload where raw compute matters, the RTX 4000 Ada Generation is the clear choice based on available evidence.

The RTX 4000 Ada Generation delivers 26.73 TFLOPS FP32 and 26.73 TFLOPS FP16 at a 1:1 ratio. The Intel Arc Pro B390 delivers 7.680 TFLOPS FP32 and 15.36 TFLOPS FP16 at a 2:1 ratio. The NVIDIA part offers 3.5 times the FP32 throughput and 1.7 times the FP16 throughput. Pixel rate favors NVIDIA at 139.2 GPixel/s versus 60.00 GPixel/s. Texture rate favors NVIDIA at 417.6 GTexel/s versus 120.0 GTexel/s.

The RTX 4000 Ada Generation also has dedicated memory. Its 20 GB GDDR6 frame buffer with 360.0 GB/s bandwidth provides predictable performance. The Intel part’s system shared memory makes its bandwidth system dependent, introducing variability that the NVIDIA card avoids.

The Intel Arc Pro B390 does have advantages in the data. Its 80 W TDP is lower than the 130 W TDP of the RTX 4000 Ada Generation. It is an integrated part, requiring no power connectors and no separate slot. For compact or power-constrained portable devices, the Intel part fits where a single-slot 245 mm card cannot.

Users who need a discrete workstation GPU with measured performance, large memory capacity, and AI tensor core support should choose the NVIDIA RTX 4000 Ada Generation. Users who require an integrated graphics solution with low power draw and no additional hardware should consider the Intel Arc Pro B390, but they must accept unmeasured performance and system-dependent memory behavior.

Where Each One Wins

The NVIDIA RTX 4000 Ada Generation wins in every measured compute category. Its FP32 throughput of 26.73 TFLOPS dwarfs the Intel part’s 7.680 TFLOPS. Its FP16 throughput of 26.73 TFLOPS exceeds the Intel part’s 15.36 TFLOPS. The pixel rate of 139.2 GPixel/s more than doubles the Intel part’s 60.00 GPixel/s. The texture rate of 417.6 GTexel/s is 3.5 times the Intel part’s 120.0 GTexel/s.

The RTX 4000 Ada Generation wins in memory capacity and bandwidth. Its dedicated 20 GB GDDR6 frame buffer with 360.0 GB/s bandwidth provides consistent performance. The Intel part’s system shared memory makes bandwidth dependent on the host system, creating a variable performance profile.

The RTX 4000 Ada Generation wins in hardware features. Its 192 tensor cores enable AI acceleration, a capability the Intel part lacks. Its 48 RT cores provide four times the ray tracing hardware of the Intel part’s 12 RT cores. Its 6144 shading units and 192 TMUs provide substantial parallel processing resources.

The Intel Arc Pro B390 wins in power efficiency and integration. Its 80 W TDP is 50 W lower than the RTX 4000 Ada Generation’s 130 W TDP. It occupies the IGP slot width, requiring no expansion slot. It uses no power connectors, simplifying installation in portable devices. Its display outputs are portable device dependent, aligning with integrated use cases.

The Intel part also wins on boost clock. Its 2500 MHz boost exceeds the RTX 4000 Ada Generation’s 2175 MHz boost. This higher boost clock partially compensates for its lower base clock of 300 MHz versus 1500 MHz, but the NVIDIA part’s massive execution unit count still dominates throughput.

The RTX 4000 Ada Generation wins on form factor flexibility for desktop workstations. Its single-slot design with 4x DisplayPort 1.4a outputs suits multi-monitor setups. Its PCIe 4.0 x16 interface provides a standard connection path. The Intel part’s IGP bus interface limits it to systems with the Panther Lake chip integrated.

For workloads requiring maximum compute throughput, dedicated memory, AI tensor operations, or ray tracing density, the RTX 4000 Ada Generation is the data-backed winner. For ultra-low-power integrated graphics in portable devices, the Intel Arc Pro B390 offers a functional path, though its performance remains unmeasured in the database.
