Architecture Differences

The two GPUs represent fundamentally different design philosophies. The Intel Arc Pro B390 is an integrated graphics processor built on the Panther Lake chip with Xe3-LPG architecture, fabricated on Intel's 3 nm process. It is part of the Arc Graphics-WM generation and serves as the successor to HD Graphics-WM. The NVIDIA RTX 5880 Ada Generation is a discrete workstation card built on the AD102 chip with Ada Lovelace architecture, fabricated on TSMC's 5 nm process. It belongs to the GeForce 50-series and the Workstation Ada generation.

The transistor counts reveal a massive scale difference. The NVIDIA chip contains 76,300 million transistors on a 609 mm² die, achieving a transistor density of 125.3M per mm². The Intel chip's transistor count and die size are listed as unknown in the database. The NVIDIA card uses a 5 nm process from TSMC, while the Intel part uses a 3 nm process from Intel's own foundry.

Compute resources differ by an order of magnitude. The RTX 5880 Ada Generation delivers 14,080 shading units, 440 TMUs, 176 ROPs, 110 ray tracing cores, and 440 tensor cores. The Intel Arc Pro B390 provides 1,536 shading units, 48 TMUs, 24 ROPs, and 12 ray tracing cores, with no tensor core count recorded. This disparity extends to the compute throughput figures: the NVIDIA card achieves 69.27 TFLOPS FP32 and 69.27 TFLOPS FP16 with a 1:1 ratio, while the Intel part reaches 7.680 TFLOPS FP32 and 15.36 TFLOPS FP16 with a 2:1 ratio.

The memory subsystems could not be more different. The NVIDIA card is equipped with 48 GB of GDDR6 memory on a 384-bit bus, delivering 864.0 GB/s of bandwidth. The Intel part uses system shared memory with system dependent bandwidth, meaning its performance is tied to the host platform's memory configuration rather than dedicated VRAM.

Clock behavior also diverges. The NVIDIA card has a 975 MHz base clock and 2460 MHz boost clock. The Intel part has a 300 MHz base clock and 2500 MHz boost clock. Despite the lower base clock, the Intel part's boost clock is slightly higher, though this advantage is meaningless given the enormous compute resource gap.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA card's API support matches the Intel part's, indicating both are current-generation products with modern feature sets.

Head-to-Head Benchmarks

The database contains recorded benchmark results for the NVIDIA RTX 5880 Ada Generation across multiple tests, while the Intel Arc Pro B390 has no recorded benchmark scores. This absence of data for the Intel part makes direct comparison impossible, but the NVIDIA card's scores can be contextualized against its nearest rivals.

The RTX 5880 Ada Generation achieves a Geekbench OpenCL score of 326,898. In Passmark tests, it scores 167 in DirectX 10, 228 in DirectX 11, 70 in DirectX 12, and 335 in DirectX 9. Its Passmark G2D score is 777, G3D score is 25,096, and GPU compute score is 14,208.

The average benchmark score for the RTX 5880 Ada Generation is 45,972, placing it at the 85th percentile among all GPUs. Its nearest rivals in the database are the NVIDIA RTX A2000 with an average score of 46,043 and a delta of -0.2%, the Intel Arc A730M with 45,592 and a delta of 0.8%, the AMD Radeon Pro 5500 XT with 45,384 and a delta of 1.3%, and the AMD Radeon RX 5600M with 46,601 and a delta of -1.4%.

The delta percentages indicate that the RTX 5880 Ada Generation is essentially tied with its closest competitors. It trails the RTX A2000 by 0.2% and the RX 5600M by 1.4%, while leading the Arc A730M by 0.8% and the Radeon Pro 5500 XT by 1.3%. These are all single-digit percentage differences, suggesting that the RTX 5880 Ada Generation sits in a competitive performance band rather than dominating its price-adjacent peers.

The Intel Arc Pro B390 has no benchmark entries, no average score, and no nearest rivals recorded in the database. Its percentile ranking of 50 among all GPUs appears to be a default or estimated value rather than a measurement-derived figure. This means the database cannot provide any validated performance data for the Intel part.

The wins counter shows zero wins for both GPUs in head-to-head comparisons, reflecting the absence of paired benchmark runs between these two specific products.

The Verdict

The recorded data presents a stark asymmetry. The NVIDIA RTX 5880 Ada Generation is a fully characterized discrete workstation GPU with 48 GB of dedicated GDDR6 memory, 864.0 GB/s of bandwidth, 69.27 TFLOPS of FP32 compute, and a comprehensive set of benchmark scores. It operates at the 85th percentile among all GPUs and delivers an average benchmark score of 45,972.

The Intel Arc Pro B390 is an integrated GPU with system shared memory, 7.680 TFLOPS of FP32 compute, and no recorded benchmark performance. Its specification sheet shows 1,536 shading units against the NVIDIA card's 14,080, 48 TMUs against 440, and 24 ROPs against 176. The compute throughput gap is roughly 9x in FP32, and the memory bandwidth situation is not directly comparable because the Intel part depends on system memory.

Organizations requiring validated workstation GPU performance should select the RTX 5880 Ada Generation based on the benchmark data. The 285 W TDP and dual-slot form factor indicate a dedicated add-in card with its own cooling and power delivery. The 267 mm length and 112 mm height define its physical footprint.

The Intel Arc Pro B390, as an integrated processor with 80 W TDP and no power connectors, targets systems where a discrete GPU is not feasible. Its lack of recorded benchmarks means the database cannot validate any performance claims for this part. Users needing a known quantity for GPU-accelerated workloads have only one option in this comparison with empirical data: the RTX 5880 Ada Generation.

The production status for both parts is Active, and both were released within two years of each other: the NVIDIA card on January 4, 2024, and the Intel part on January 26, 2026. The NVIDIA card's predecessor is Workstation Ampere and its successor is Blackwell PRO W, while the Intel part's predecessor is HD Graphics-WM with no successor listed.
