Intel Arc B390 vs NVIDIA RTX 5880 Ada Generation Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between the Intel Arc B390 and the NVIDIA RTX 5880 Ada Generation. The recorded data instead places each product in separate performance brackets, and the gap between those brackets is substantial. The Intel Arc B390 holds a single recorded 3DMark Steel Nomad DX12 score of 1482, which places it at the 9th percentile among all GPUs in the database. Its nearest rivals, all at the low end of the performance spectrum, include the NVIDIA GeForce GT 520MX at 1463 (1.3% behind), the NVIDIA GeForce 800M at 1460 (1.5% behind), the NVIDIA GeForce GT 625 OEM at 1446 (2.5% behind), and the NVIDIA GeForce GT 710 at 1443 (2.7% behind). These deltas are narrow, indicating the Arc B390 sits in a crowded field of entry-level parts where a 2.7% difference separates the top from the bottom of its immediate peer group.

The NVIDIA RTX 5880 Ada Generation, by contrast, records a broader benchmark profile. Its average benchmark score across eight tests is 45972, which places it at the 85th percentile among all GPUs. Its nearest rivals include the NVIDIA RTX A2000 at 46043 (0.2% ahead of the RTX 5880), the Intel Arc A730M at 45592 (0.8% behind), the AMD Radeon Pro 5500 XT at 45384 (1.3% behind), and the AMD Radeon RX 5600M at 46601 (1.4% ahead). The RTX 5880's closest competitor, the RTX A2000, is statistically indistinguishable in average score, yet the RTX 5880 carries dramatically higher raw specifications, a point explored in later sections.

The single-score comparison is stark. The Arc B390's 1482 in 3DMark Steel Nomad DX12 is a fraction of the RTX 5880's average of 45972. Even the RTX 5880's weakest recorded test, PassMark DirectX 12 at 70, undercuts the Arc B390's 1482, but that test measures a different workload. The strongest RTX 5880 result, Geekbench OpenCL at 326898, dwarfs the Arc B390's entire benchmark history. No extrapolation is needed: the record shows the RTX 5880 operates in a performance class roughly thirty times higher by average score, and the percentile gap (9th versus 85th) confirms that the two cards serve entirely different segments of the market.

Where Each One Wins

The RTX 5880 Ada Generation wins decisively across raw compute metrics. Its FP32 throughput of 69.27 TFLOPS is roughly nine times the Arc B390's 7.680 TFLOPS. Its FP16 output is also 69.27 TFLOPS at a 1:1 ratio, whereas the Arc B390 delivers 15.36 TFLOPS at a 2:1 ratio, meaning the RTX 5880's FP16 advantage is even larger when accounting for the ratio difference. Pixel rate favors the RTX 5880 at 433.0 GPixel/s versus 60.00 GPixel/s, and texture rate favors it at 1,082.4 GTexel/s versus 120.0 GTexel/s. The RTX 5880 also carries 110 ray tracing cores and 440 tensor cores, while the Arc B390 has 12 ray tracing cores and no tensor cores recorded.

The Arc B390's wins are confined to efficiency-oriented characteristics. It has a TDP of 80 W versus 285 W for the RTX 5880, and it requires no power connectors, as it is an integrated graphics processor (IGP). The RTX 5880 requires a single 16-pin connector and a suggested 600 W power supply. The Arc B390's base clock of 300 MHz and boost clock of 2500 MHz both exceed the RTX 5880's respective clocks in boost terms, but this does not translate into compute wins. The Arc B390 also wins on physical footprint, being an IGP with no slot width, whereas the RTX 5880 is a dual-slot card measuring 267 mm in length and 112 mm in height.

For workloads, the RTX 5880 is the only option for high-throughput tasks. Its Geekbench OpenCL score of 326898 and PassMark G3D score of 25096 indicate strong general compute and 3D rendering. Its PassMark GPU Compute score of 14208 further confirms compute capability. The Arc B390 has no equivalent test scores in the database, so its performance outside the single 3DMark test is unrecorded. For any task requiring substantial memory, the RTX 5880's 48 GB GDDR6 pool with 864.0 GB/s bandwidth is the clear choice; the Arc B390 relies on system memory with dependent bandwidth.

Specification Differences

The two cards differ in nearly every measurable specification. The Arc B390 uses 3 nm process technology from Intel's foundry, while the RTX 5880 uses 5 nm from TSMC. The RTX 5880 has a recorded transistor count of 76,300 million on a 609 mm² die, with a transistor density of 125.3M per mm². The Arc B390's transistor count and die size are listed as unknown.

Memory differs fundamentally: the Arc B390 uses system shared memory with no dedicated size, type, bus width, or bandwidth, while the RTX 5880 has 48 GB of GDDR6 on a 384-bit bus with 864.0 GB/s bandwidth and an effective memory clock of 18 Gbps. The Arc B390's memory clock is listed as system shared.

Physical specifications diverge completely. The Arc B390 is an IGP with no slot width, no power connectors, and display outputs dependent on the portable device. The RTX 5880 is a dual-slot card with a 16-pin power connector, a suggested 600 W power supply, a PCIe 4.0 x16 interface, and four DisplayPort 1.4a outputs. The RTX 5880's dimensions are 267 mm by 112 mm; the Arc B390 has no recorded dimensions.

Compute resources differ by an order of magnitude. The Arc B390 has 1,536 shading units, 48 TMUs, 24 ROPs, and 12 ray tracing cores. The RTX 5880 has 14,080 shading units, 440 TMUs, 176 ROPs, 110 ray tracing cores, and 440 tensor cores. The Arc B390 has no tensor cores recorded.

Clock behavior also differs. The Arc B390 has a base clock of 300 MHz and a boost clock of 2500 MHz. The RTX 5880 has a base clock of 975 MHz and a boost clock of 2460 MHz. Both cards advertise identical API support: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Architecture Differences

The Intel Arc B390 is built on the Xe3-LPG architecture, specifically from the Panther Lake chip within the Arc Graphics-M (Panther Lake) generation. The RTX 5880 Ada Generation uses the Ada Lovelace architecture on the AD102 chip, belonging to the Workstation Ada (x000A) generation. The Arc B390's process node is 3 nm fabricated by Intel, while the RTX 5880 uses 5 nm fabricated by TSMC.

The RTX 5880's architecture includes tensor cores (440 of them) and ray tracing cores (110), which are absent or minimal on the Arc B390 (12 ray tracing cores, no tensor cores). The RTX 5880's FP16 performance matches its FP32 at 69.27 TFLOPS with a 1:1 ratio, indicating full-rate half-precision compute. The Arc B390's FP16 of 15.36 TFLOPS is achieved at a 2:1 ratio, meaning it halves the FP32 rate. This architectural choice suggests the RTX 5880 is designed for workloads that demand equal FP16 and FP32 throughput, while the Arc B390 prioritizes power efficiency.

The RTX 5880's predecessor is Workstation Ampere, and its successor is Blackwell PRO W, positioning it in a clear generational lineage. The Arc B390 has no predecessor or successor recorded. The release dates also differ: the Arc B390 entered production with a release date of 2026-01-26, while the RTX 5880 was released on 2024-01-04. Both are listed as active production status.

Memory architecture reflects their different roles. The RTX 5880's dedicated 48 GB GDDR6 with 864.0 GB/s bandwidth is a workstation-class memory subsystem. The Arc B390's system shared memory means it draws from the host system's RAM, which is typically slower and shared with the CPU. The RTX 5880's 384-bit bus width versus the Arc B390's system dependent bus further underscores the architectural gap.

The Verdict

The data points to a categorical difference in performance class. The Intel Arc B390, with its 9th percentile ranking and a single benchmark score of 1482, is positioned among entry-level discrete or integrated graphics solutions. Its nearest rivals are all older NVIDIA mobile or OEM parts, and its margins over them are between 1.3% and 2.7%. The RTX 5880 Ada Generation, at the 85th percentile with an average score of 45972, sits in the upper tier of the database, alongside workstation cards like the RTX A2000 and mobile parts like the Arc A730M.

For users selecting a GPU for high-throughput compute, rendering, or AI-adjacent workloads, the RTX 5880 is the only defensible choice from this data. Its 69.27 TFLOPS FP32, 69.27 TFLOPS FP16 at 1:1 ratio, 110 ray tracing cores, and 440 tensor cores provide a hardware feature set that the Arc B390 cannot match. The 48 GB memory capacity and 864.0 GB/s bandwidth are workstation-class specifications.

The Arc B390's role is limited to low-power integrated graphics. Its 80 W TDP, lack of power connectors, and IGP form factor make it suitable for compact or portable systems where add-in card installation is impossible. Its boost clock of 2500 MHz is higher than the RTX 5880's, but that advantage does not appear in any recorded benchmark result. The Arc B390's percentile rank of 9% indicates it outperforms only a small fraction of the database, while the RTX 5880 outperforms 85% of all listed GPUs.

The RTX 5880's nearest rival, the RTX A2000, scores 46043, which is 0.2% higher. This near-tie in average score is notable because the RTX 5880 carries substantially more memory (48 GB versus the A2000's unspecified capacity in the rival data) and higher core counts. The performance parity suggests that average benchmark scores may not fully capture the RTX 5880's advantage in memory-bound or high-core-count workloads. The Arc B390, by comparison, has no such ambiguity: it leads its rivals by at most 2.7%, and no recorded test suggests it can approach the RTX 5880's performance tier.

Selecting between them requires no trade-off analysis. The RTX 5880 is a dual-slot, 285 W workstation card with a 16-pin connector. The Arc B390 is an integrated GPU with no physical installation requirements. Any workload that fits the RTX 5880's capabilities should use it. Any system that cannot accommodate a discrete card will rely on the Arc B390, accepting its 9th percentile performance. The database records no head-to-head benchmark, but the average score differential of 44,490 points between the two cards makes the performance hierarchy unambiguous.
