Intel Arc Pro B390 vs NVIDIA GeForce RTX 4090 D Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark comparisons between the Intel Arc Pro B390 and the NVIDIA GeForce RTX 4090 D. The database lists no shared test results, no comparative scores, and no win counts for either product. This absence of overlapping benchmarks means a direct numerical comparison across identical workloads is not possible from the available measurements.

What the database does provide is a set of standalone benchmark results for the NVIDIA GeForce RTX 4090 D. Three tests are recorded: 3DMark Steel Nomad DX12 at 8,587 points, Geekbench OpenCL at 278,621 points, and Geekbench Vulkan at 246,941 points. The average benchmark score across these tests is 178,050. This places the RTX 4090 D in the 98th percentile of all GPUs in the database, indicating it outperforms the vast majority of recorded graphics hardware.

The Intel Arc Pro B390 has no benchmark entries in the database. Its average benchmark score is listed as 0, and its percentile rank is 50. Without any recorded test scores, the database cannot establish a performance baseline for the Arc Pro B390. The percentile value of 50 is a default placeholder rather than a measured result, as the absence of benchmark data means no meaningful percentile can be derived from actual performance.

When examining the nearest rivals of the RTX 4090 D, the data shows how close its performance sits to other high-end cards. The NVIDIA RTX PRO 5000 Blackwell has an average score of 182,109, which is 2.2% higher than the RTX 4090 D. The NVIDIA A100 SXM4 80 GB scores 183,725, a 3.1% advantage. The NVIDIA RTX 5000 Ada Generation reaches 184,664, 3.6% ahead. The NVIDIA A100 SXM4 40 GB leads with 187,147, 4.9% higher. These margins are all within 5%, demonstrating that the RTX 4090 D sits in a tightly contested performance tier.

The lack of Intel Arc Pro B390 benchmark data means the database cannot confirm any single win for either product. The wins counter shows 0 for both items. This is not a statement of equivalence; it is a reflection of missing comparative measurements. Users seeking a direct performance verdict will need to rely on the RTX 4090 D's standalone scores and the architectural differences outlined below.

Architecture Differences

The two GPUs diverge fundamentally in their design and target usage. The Intel Arc Pro B390 uses the Panther Lake chip with the Xe3-LPG architecture, built on a 3 nm process at Intel's own foundry. It belongs to the Arc Graphics-WM (Panther Lake) generation. The NVIDIA GeForce RTX 4090 D uses the AD102 chip with Ada Lovelace architecture, manufactured on a 5 nm process by TSMC. NVIDIA places it in the GeForce 40-series generation.

The RTX 4090 D contains 76,300 million transistors on a 609 mm² die, giving it a transistor density of 125.3 million per square millimeter. The Intel Arc Pro B390 has an unknown transistor count and die size, so no density comparison can be made. What is clear is the scale difference: the NVIDIA chip is a discrete, triple-slot card measuring 304 mm in length, 137 mm in height, and 61 mm in width. The Intel part is an integrated graphics processor (IGP) with no expansion slot width, no power connectors, and no dimensions listed. It draws its power from the host system rather than a dedicated supply.

Clock behavior highlights the different design philosophies. The Arc Pro B390 has a base clock of 300 MHz and a boost clock of 2,500 MHz. The RTX 4090 D starts at 2,280 MHz base and boosts to 2,520 MHz. While the boost clocks are similar, the base clock disparity is enormous: the NVIDIA card runs at over seven times the Intel part's base frequency. This suggests the Arc Pro B390 is designed for power efficiency and integrated operation, while the RTX 4090 D is built for sustained high-frequency workloads.

Memory architecture is another major split. The Arc Pro B390 uses system shared memory, with its size, type, bus width, and bandwidth all listed as "System Shared" or "System Dependent." This means it borrows from the host system's RAM and has no dedicated video memory. The RTX 4090 D has 24 GB of GDDR6X memory on a 384-bit bus, delivering 1.01 TB/s of bandwidth. The memory clock is listed at 1,313 MHz with 21 Gbps effective speed. This dedicated high-bandwidth memory is essential for the RTX 4090 D's performance class.

Compute resources show the NVIDIA card's overwhelming numerical advantage. The RTX 4090 D has 14,592 shading units, 456 texture mapping units, 176 ROPs, 114 RT cores, and 456 tensor cores. The Arc Pro B390 has 1,536 shading units, 48 TMUs, 24 ROPs, and 12 RT cores, with no tensor core count listed. In FP32 compute, the RTX 4090 D delivers 73.54 TFLOPS, while the Arc Pro B390 manages 7.680 TFLOPS. That is roughly a 9.6x difference. The RTX 4090 D also outputs 1,149.1 GTexel/s in texture rate and 443.5 GPixel/s in pixel rate, versus 120.0 GTexel/s and 60.00 GPixel/s for the Intel part.

FP16 performance tells a similar story but with a different ratio. The RTX 4090 D achieves 73.54 TFLOPS at a 1:1 ratio, meaning FP16 and FP32 are processed at the same rate. The Arc Pro B390 reaches 15.36 TFLOPS at a 2:1 ratio, where FP16 is twice the FP32 rate. Even with the 2:1 advantage, the Intel part's FP16 output is only about one-fifth of the NVIDIA card's.

Power consumption reflects the performance gap. The RTX 4090 D has a TDP of 425 W, requires a single 16-pin power connector, and needs an 800 W suggested power supply. The Arc Pro B390 has an 80 W TDP, uses no power connectors, and has no suggested PSU because it draws from the host system. The NVIDIA card uses PCIe 4.0 x16 as its bus interface, while the Intel part uses IGP.

Display outputs differ in practicality. The RTX 4090 D has 1x HDMI 2.1 and 3x DisplayPort 1.4a. The Arc Pro B390's display outputs are "Portable Device Dependent," meaning they rely entirely on the host laptop or portable device. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Production status and release timing also differ. The Arc Pro B390 is Active and was released on 2026-01-26, with the HD Graphics-WM as its predecessor. The RTX 4090 D is End-of-life, released on 2023-12-27, with the GeForce 30 series as predecessor and GeForce 50 as successor. The launch MSRP for the RTX 4090 D is 1,599 USD; the Arc Pro B390 has no launch MSRP recorded.

The Verdict

The data points to a straightforward conclusion: the NVIDIA GeForce RTX 4090 D is a discrete, high-power, high-performance GPU designed for demanding desktop workloads, while the Intel Arc Pro B390 is an integrated graphics solution for portable devices. The RTX 4090 D's benchmark scores place it in the 98th percentile of all GPUs, with an average score of 178,050 across three tests. The Arc Pro B390 has no recorded benchmarks, meaning the database cannot verify any level of real-world performance for it.

The architectural differences are decisive. The RTX 4090 D has 9.6x the FP32 throughput, 9.6x the texture rate, 7.4x the pixel rate, and a dedicated 24 GB memory subsystem with 1.01 TB/s bandwidth. It also carries 456 tensor cores, which the Intel part lacks. The RTX 4090 D is a triple-slot card with its own power delivery and a 425 W TDP. The Arc Pro B390 is an IGP with an 80 W TDP and no dedicated memory.

For users who need maximum compute performance, the RTX 4090 D is the only option with measured results. Its nearest rivals are within 2.2% to 4.9% of its average score, confirming it competes at the top tier. The Arc Pro B390, by contrast, offers no benchmark data and no performance percentile beyond the default 50. The database cannot recommend it for any performance-critical workload based on available evidence.

Where Each One Wins

The NVIDIA GeForce RTX 4090 D wins in every measured performance category. Its FP32 throughput of 73.54 TFLOPS dwarfs the Arc Pro B390's 7.680 TFLOPS. Its texture rate of 1,149.1 GTexel/s is roughly 9.6 times the Intel part's 120.0 GTexel/s. Pixel rate shows a similar pattern: 443.5 GPixel/s versus 60.00 GPixel/s. The RTX 4090 D also has 456 TMUs and 176 ROPs, compared to 48 and 24 respectively on the Arc Pro B390. RT core counts are 114 versus 12.

The RTX 4090 D wins on memory as well. A dedicated 24 GB GDDR6X pool with 1.01 TB/s bandwidth provides consistent high-speed access across workloads. The Arc Pro B390's reliance on system shared memory introduces dependency on host RAM performance, which the database lists as "System Dependent" and therefore variable.

The Arc Pro B390 wins on power efficiency and integration footprint. Its 80 W TDP is less than one-fifth of the RTX 4090 D's 425 W. It requires no power connectors, no external PSU recommendation, and fits as an IGP with no slot width. This makes it suitable for portable devices where space and battery are constrained. The RTX 4090 D demands a triple-slot chassis, a 1x 16-pin power connector, and an 800 W PSU.

The Arc Pro B390 also uses a newer manufacturing process at 3 nm versus 5 nm, though this does not translate into performance advantages in the recorded data. Its base clock of 300 MHz is far lower than the RTX 4090 D's 2,280 MHz, but its boost clock of 2,500 MHz is nearly identical to the NVIDIA card's 2,520 MHz. This suggests the Intel part can reach competitive peak frequencies when needed, but its integrated design limits sustained output.

For FP16 workloads, the Arc Pro B390's 2:1 ratio means it processes half-precision at 15.36 TFLOPS, which is still only about one-fifth of the RTX 4090 D's 73.54 TFLOPS at 1:1. The NVIDIA card's 1:1 ratio means FP16 provides no throughput advantage over FP32, but the absolute numbers remain far higher.

In terms of longevity, the RTX 4090 D is End-of-life with the GeForce 50 as successor, while the Arc Pro B390 is Active. However, active production status does not compensate for the lack of benchmark data. The database's only objective performance evidence comes from the RTX 4090 D's three recorded tests.
