Intel Arc Pro B390 vs NVIDIA GeForce RTX 4080 SUPER Comparison

Where Each One Wins

The recorded data presents an extreme asymmetry between these two graphics solutions. The Intel Arc Pro B390, an integrated graphics processor within the Panther Lake chip, carries no benchmark entries in the database. Its average benchmark score is recorded as 0, and its percentile versus all GPUs sits at 50. The NVIDIA GeForce RTX 4080 SUPER, by contrast, holds a substantial set of measured results, an average benchmark score of 54209, and an 86th percentile rank among all GPUs.

For the Arc Pro B390, the absence of benchmark data means the database cannot assign it any wins in any workload category. Every head-to-head comparison field is empty, and the wins counter for Intel is 0. The product is positioned as an integrated processor solution with an 80 W TDP and system-shared memory, which suggests it targets platforms where a discrete card is not present. In that context, its role is to provide graphics output and basic acceleration rather than to compete with high-end discrete offerings.

The RTX 4080 SUPER wins in every measurable category by default. With 10240 shading units, 320 TMUs, and 112 ROPs, its raw throughput metrics dwarf those of the integrated part. The benchmark scores confirm this: in Passmark G3D, the NVIDIA card scores 34245, while in Geekbench Vulkan it reaches 260075. The Intel part has no comparable recorded scores. The use-case split is therefore clear: the RTX 4080 SUPER is the only option in this comparison with any measured performance data, making it the sole winner in every benchmark category, including DirectX 9, 10, 11, 12, OpenCL, Vulkan, G2D, G3D, and GPU compute.

Architecture Differences

The two products come from fundamentally different design philosophies and manufacturing processes. The Intel Arc Pro B390 uses the Panther Lake chip with the Xe3-LPG architecture, built on a 3 nm process node at Intel's own foundry. Its transistor count and die size are both listed as unknown in the database. The NVIDIA GeForce RTX 4080 SUPER employs the AD103 chip with Ada Lovelace architecture, fabricated on a 5 nm process at TSMC. The NVIDIA chip contains 45,900 million transistors on a 379 mm² die, yielding a transistor density of 121.1M per mm².

The clock behavior differs markedly. The Intel part runs at a 300 MHz base clock and boosts to 2500 MHz. The RTX 4080 SUPER starts at 2295 MHz base and boosts to 2550 MHz. Memory architecture is entirely different: the Intel solution uses system-shared memory with system-dependent bandwidth, while the NVIDIA card has 16 GB of dedicated GDDR6X memory on a 256-bit bus, delivering 736.3 GB/s of bandwidth. The memory clock for NVIDIA is listed as 1438 MHz with 23 Gbps effective data rate.

Compute resources vary by an order of magnitude. The Arc Pro B390 has 1536 shading units, 48 TMUs, 24 ROPs, and 12 ray tracing cores. The RTX 4080 SUPER has 10240 shading units, 320 TMUs, 112 ROPs, and 80 ray tracing cores. Additionally, the NVIDIA card includes 320 tensor cores, a feature entirely absent from the Intel specification. The Intel part reports FP32 performance of 7.680 TFLOPS and FP16 of 15.36 TFLOPS with a 2:1 ratio. The NVIDIA part reaches 52.22 TFLOPS for both FP32 and FP16 with a 1:1 ratio.

The process node difference is notable: 3 nm for Intel versus 5 nm for NVIDIA. This gives the Intel part a theoretical density advantage, but the lack of transistor and die size data prevents a direct comparison. The Intel architecture is newer in generation, listed under Arc Graphics-WM (Panther Lake), while NVIDIA is in the GeForce 40 generation with Ada Lovelace. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API feature parity exists despite the hardware gulf.

Head-to-Head Benchmarks

The database contains no paired head-to-head benchmark results between these two products. The headToHeadBenchmarks field is empty, and neither product has a wins counter above 0. This is the critical finding: the Intel Arc Pro B390 has zero benchmark entries, while the RTX 4080 SUPER has ten recorded tests.

For the RTX 4080 SUPER, the benchmark suite reveals its strengths across different APIs. In 3DMark Steel Nomad DX12, it scores 6600. Geekbench OpenCL yields 219065, and Geekbench Vulkan reaches 260075. The Passmark suite shows DirectX 9 at 381, DirectX 10 at 193, DirectX 11 at 301, and DirectX 12 at 134. The G2D score is 1270, while G3D reaches 34245. GPU compute scores 19822.

The average benchmark score for the RTX 4080 SUPER is 54209, placing it at the 86th percentile among all GPUs in the database. Its nearest rivals are the NVIDIA GeForce RTX 4080 with an average score of 54247 and a delta of -0.1%, the AMD Radeon Pro W5700X at 54828 with -1.1%, the AMD Radeon RX 6750 GRE 12 GB at 55698 with -2.7%, and the AMD Radeon 8060S at 55757 with -2.8%. These deltas are all negative, meaning the RTX 4080 SUPER sits slightly below each rival in average score, though the margins are small, ranging from 0.1% to 2.8%.

For the Intel Arc Pro B390, the average benchmark score is 0, and its percentile is 50. With no recorded tests, there is no data point to compare against the NVIDIA card, nor against any other product in the database. The Intel part cannot be ranked relative to the RTX 4080 SUPER in any specific workload because no measurement exists.

Specification Differences

The two products differ across nearly every specification field in the database. The manufacturing process differs: Intel uses 3 nm at its own foundry, while NVIDIA uses 5 nm at TSMC. The Intel chip has no transistor or die size data, whereas NVIDIA lists 45,900 million transistors and a 379 mm² die. The RTX 4080 SUPER also has a transistor density figure of 121.1M per mm², which the Intel part lacks.

Clock speeds diverge significantly. The Intel base clock is 300 MHz versus 2295 MHz for NVIDIA, and boost clocks are 2500 MHz versus 2550 MHz respectively. Memory configurations are incompatible: Intel uses system-shared memory with system-dependent bandwidth, while NVIDIA has 16 GB of GDDR6X on a 256-bit bus with 736.3 GB/s bandwidth. The memory clock differs as well, with NVIDIA running at 1438 MHz and 23 Gbps effective.

Compute unit counts show a massive gap. Shading units: 1536 for Intel versus 10240 for NVIDIA. TMUs: 48 versus 320. ROPs: 24 versus 112. Ray tracing cores: 12 versus 80. Tensor cores: none listed for Intel versus 320 for NVIDIA. Pixel rate: 60.00 GPixel/s for Intel versus 285.6 GPixel/s for NVIDIA. Texture rate: 120.0 GTexel/s versus 816.0 GTexel/s. FP32: 7.680 TFLOPS versus 52.22 TFLOPS. FP16: 15.36 TFLOPS with 2:1 ratio versus 52.22 TFLOPS with 1:1 ratio.

Power and physical specifications also differ. The Intel TDP is 80 W with no power connectors and an IGP slot width. The NVIDIA TDP is 320 W, uses a triple-slot design with a single 16-pin connector, and requires a 700 W suggested PSU. The bus interface is IGP for Intel and PCIe 4.0 x16 for NVIDIA. Display outputs are portable device dependent for Intel versus 1x HDMI 2.13x DisplayPort 1.4a for NVIDIA. Dimensions are absent for Intel but present for NVIDIA: 310 mm length, 140 mm height, 61 mm width. Production status shows Intel as active and NVIDIA as end-of-life. Release dates differ: Intel on 2026-01-26 and NVIDIA on 2024-01-30. The NVIDIA predecessor is GeForce 30 and successor is GeForce 50, while Intel lists HD Graphics-WM as predecessor. The launch MSRP for the RTX 4080 SUPER is 999 USD; the Intel part has no recorded launch MSRP.
