Intel Arc Pro B390 vs NVIDIA RTX PRO 4000 Blackwell Comparison

Head-to-Head Benchmarks

The recorded data sets a stark contrast between these two workstation-oriented GPUs. The Intel Arc Pro B390 carries no benchmark entries in the database, while the NVIDIA RTX PRO 4000 Blackwell has a full suite of nine recorded tests. Consequently, the head-to-head comparison is one-sided by data availability, not necessarily by architectural merit. The RTX PRO 4000 Blackwell posts an average benchmark score of 27135, placing it in the 72nd percentile of all GPUs tracked. The Arc Pro B390 sits at the 50th percentile with an average score of 0, a placeholder reflecting the absence of submitted results rather than a measured performance level.

Within the RTX PRO 4000 Blackwell's own benchmark results, the strongest showing comes from Geekbench Vulkan, where it records 194168 points. The Passmark G3D suite returns 28427 points, and the Passmark GPU Compute test yields 14805 points. DirectX 9 legacy performance reaches 354 points, DirectX 11 hits 276, and DirectX 10 scores 173. DirectX 12 records 97 points, while the 2D graphics test produces 1265 points. The 3DMark Steel Nomad DX12 test, a modern workload, delivers 4648 points.

For the Arc Pro B390, no comparable figures exist in the database. The nearest rival comparisons for the RTX PRO 4000 Blackwell provide context for its standing. The AMD Radeon RX 6700 XT averages 27425 points, putting the RTX PRO 4000 Blackwell 1.1% behind it. The NVIDIA GeForce RTX 4070 Mobile averages 27435 points, also 1.1% ahead of the RTX PRO 4000 Blackwell. The NVIDIA GeForce RTX 3090 averages 27565 points, a 1.6% advantage over the RTX PRO 4000 Blackwell. Conversely, the RTX PRO 4000 Blackwell sits 1.7% ahead of the NVIDIA RTX A4000, which averages 26683 points.

These deltas are tight, all within a 3.3 percentage point band across four rivals. The RTX PRO 4000 Blackwell is effectively a peer of those cards in aggregate benchmark performance, slightly trailing the gaming-oriented RX 6700 XT and RTX 3090 while edging out the older RTX A4000 workstation card. The 3DMark Steel Nomad result of 4648 points and the Geekbench Vulkan score of 194168 represent the most demanding recorded workloads, and both sit well above typical integrated-graphics territory, confirming the RTX PRO 4000 Blackwell handles modern DX12 and Vulkan applications.

The Arc Pro B390, with no recorded benchmarks, cannot be ranked against these numbers. The database shows no wins for either product because no head-to-head test entries exist. Any direct comparison must rely on specification-level analysis, which appears in later sections.

Where Each One Wins

The RTX PRO 4000 Blackwell wins every category where measurement data exists. It has recorded scores across nine tests spanning legacy DirectX 9 through modern DX12 and Vulkan. Its Passmark G3D score of 28427 and Geekbench Vulkan score of 194168 indicate strong general 3D rendering and compute throughput. The Passmark GPU Compute score of 14805 shows dedicated compute workloads, such as those used in scientific or engineering simulations, run at a level consistent with the desktop GPU rivals listed in the database.

The Arc Pro B390 wins only in the absence of competing data. As an IGP (integrated graphics processor) with system-shared memory, its performance depends entirely on the host platform's memory subsystem, a factor the database records as "System Dependent" for bandwidth. The chip's 7.680 TFLOPS FP32 rate and 60.00 GPixel/s pixel rate are fixed silicon limits, but real-world results would scale with shared memory speed and capacity. The RTX PRO 4000 Blackwell, by contrast, has dedicated 24 GB of GDDR7 memory on a 192-bit bus delivering 672.0 GB/s of bandwidth, removing that variable from its performance profile.

For workstation tasks, the RTX PRO 4000 Blackwell's dedicated memory and 36.83 TFLOPS FP32 throughput make it the clear choice where measured data matters. The Arc Pro B390's 12 ray tracing cores and 1536 shading units suggest capability in lighter workloads, but with no benchmark submissions, the database cannot confirm any advantage. The RTX PRO 4000 Blackwell's 70 ray tracing cores and 280 tensor cores point to a hardware advantage in ray-traced rendering and AI-accelerated tasks, both common in professional visualization and simulation. The Arc Pro B390 lists no tensor core count, leaving AI-focused workloads unquantified for that part.

Specification Differences

The two GPUs diverge sharply on nearly every hardware specification. The Arc Pro B390 uses a 3 nm process node from Intel, while the RTX PRO 4000 Blackwell uses a 5 nm node from TSMC. The RTX PRO 4000 Blackwell lists 45,600 million transistors on a 378 mm² die with a transistor density of 120.6M per mm²; the Arc Pro B390's transistor count and die size are both listed as unknown.

Clock speeds differ in both base and boost. The Arc Pro B390 runs at a 300 MHz base and 2500 MHz boost. The RTX PRO 4000 Blackwell has a 1230 MHz base and 2055 MHz boost. Memory clock also differs: the Arc Pro B390's memory clock is listed as "System Shared," while the RTX PRO 4000 Blackwell runs at 1750 MHz with 28 Gbps effective data rate.

The compute unit counts show a wide gap. The Arc Pro B390 has 1536 shading units, 48 texture mapping units, 24 raster output units, and 12 ray tracing cores. The RTX PRO 4000 Blackwell has 8960 shading units, 280 TMUs, 96 ROPs, 70 RT cores, and 280 tensor cores. The Arc Pro B390 lists no tensor core count.

Rates and throughput also differ. The Arc Pro B390 produces 60.00 GPixel/s pixel rate, 120.0 GTexel/s texture rate, 7.680 TFLOPS FP32, and 15.36 TFLOPS FP16 at a 2:1 ratio. The RTX PRO 4000 Blackwell produces 197.3 GPixel/s, 575.4 GTexel/s, 36.83 TFLOPS FP32, and 36.83 TFLOPS FP16 at a 1:1 ratio.

Form factor and interface differ completely. The Arc Pro B390 is an IGP with no slot width, no power connectors, and a bus interface of IGP. The RTX PRO 4000 Blackwell is a single-slot card with one 16-pin power connector, a suggested PSU of 300 W, and a PCIe 5.0 x16 bus interface. Dimensions follow suit: the RTX PRO 4000 Blackwell measures 241 mm in length, 111 mm in height, and 20 mm in width; the Arc Pro B390 has no listed dimensions.

Display outputs and memory size further separate them. The Arc Pro B390's display outputs are described as "Portable Device Dependent," while the RTX PRO 4000 Blackwell provides 4x DisplayPort 2.1b. Memory capacity is system-shared for the Arc Pro B390 versus 24 GB dedicated for the RTX PRO 4000 Blackwell. Release dates also differ, with the RTX PRO 4000 Blackwell launching earlier.

Architecture Differences

The Arc Pro B390 is built on Intel's Xe3-LPG architecture, part of the Arc Graphics-WM (Panther Lake) generation. Its chip is labeled Panther Lake. The RTX PRO 4000 Blackwell uses NVIDIA's Blackwell 2.0 architecture on the GB203 chip, part of the Blackwell PRO W (x000) generation. These are fundamentally different design philosophies: Intel's part is an integrated GPU sharing system memory, while NVIDIA's is a discrete add-in card with dedicated VRAM.

Process technology differs as well. The Arc Pro B390 uses a 3 nm node fabricated by Intel. The RTX PRO 4000 Blackwell uses a 5 nm node from TSMC. The RTX PRO 4000 Blackwell's predecessor is listed as Workstation Ada, while the Arc Pro B390's predecessor is HD Graphics-WM. Both are marked as Active production status.

The ray tracing and compute feature sets diverge. The RTX PRO 4000 Blackwell lists 70 RT cores and 280 tensor cores, enabling hardware-accelerated ray tracing and tensor operations. The Arc Pro B390 lists 12 RT cores and no tensor core entry, indicating a much smaller ray tracing presence and unlisted AI acceleration hardware. The FP16 throughput ratio also reveals a design choice: the Arc Pro B390 halves FP16 rate relative to FP32 (2:1), while the RTX PRO 4000 Blackwell runs FP16 at the same rate as FP32 (1:1), doubling its FP16 throughput relative to its own FP32 output. The RTX PRO 4000 Blackwell's FP16 output of 36.83 TFLOPS is 2.4 times the Arc Pro B390's 15.36 TFLOPS.

Memory architecture differences are structural. The Arc Pro B390 depends on system RAM, with bandwidth listed as "System Dependent" and no fixed bus width. The RTX PRO 4000 Blackwell has a fixed 192-bit GDDR7 interface with 672.0 GB/s bandwidth, providing predictable memory performance independent of host platform. The Arc Pro B390's 80 W TDP versus the RTX PRO 4000 Blackwell's 140 W TDP reflects the integrated versus discrete split, as does the absence of any power connector on the Intel part. The RTX PRO 4000 Blackwell's 4x DisplayPort 2.1b outputs versus the Arc Pro B390's portable-device-dependent outputs further confirms their intended deployment environments: one for stationary workstations, the other for mobile or compact systems.
