Intel Arc B390 vs NVIDIA RTX 5000 Ada Generation Comparison

Head-to-Head Benchmarks

The recorded data contains no shared benchmark tests between the Intel Arc B390 and the NVIDIA RTX 5000 Ada Generation, so a direct per-test comparison is not possible. Instead, the database places each product in a different performance class based on its average benchmark score and nearest rivals. The Intel Arc B390 has an average benchmark score of 1482, which places it in the 9th percentile of all GPUs. Its closest rivals in the database are legacy mobile and OEM parts: the NVIDIA GeForce GT 520MX (average score 1463, 1.3% behind), NVIDIA GeForce 800M (average score 1460, 1.5% behind), NVIDIA GeForce GT 625 OEM (average score 1446, 2.5% behind), and NVIDIA GeForce GT 710 (average score 1443, 2.7% behind). The Arc B390 leads its nearest recorded rival by 1.3 points, a margin that is within normal run-to-run variance for low-end integrated graphics.

The NVIDIA RTX 5000 Ada Generation sits in the 98th percentile of all GPUs, one of the highest positions in the database. Its average benchmark score is 184664, derived from two recorded tests: Geekbench OpenCL at 175286 and Geekbench Vulkan at 194041. The nearest rivals for this card are all high-end accelerators and workstation products. The NVIDIA A100 SXM4 80 GB scores 183725, which is 0.5% behind the RTX 5000 Ada. The NVIDIA A100 SXM4 40 GB scores 187147, putting it 1.3% ahead. The NVIDIA RTX PRO 5000 Blackwell scores 182109, 1.4% behind, and the NVIDIA GeForce RTX 4090 D scores 178050, 3.7% behind. These margins show that the RTX 5000 Ada sits in a tightly contested band at the top of the performance distribution, trading places with the A100 variants and the RTX PRO 5000 Blackwell depending on the workload.

The performance gap between the two products being compared is enormous. The RTX 5000 Ada Generation's average score of 184664 is roughly 124.6 times the Arc B390's average score of 1482. The Arc B390's best recorded result, a 3DMark Steel Nomad DX12 score of 1482, is orders of magnitude below either Geekbench result for the RTX 5000 Ada. The data indicates that these two products are not competitors; they serve entirely different segments of the GPU market.

The Arc B390 also shows a notable discrepancy between its theoretical compute rates and its actual benchmark standing. Its FP32 throughput is rated at 7.680 TFLOPS, yet its benchmark score places it near GPUs from over a decade ago. This suggests that the integrated part's performance is constrained by system-dependent factors such as shared memory bandwidth, which the database records as "System Dependent." The RTX 5000 Ada, by contrast, delivers 65.28 TFLOPS FP32 and its benchmark results confirm that compute throughput translates into top-tier measured performance.

Architecture Differences

The two GPUs come from fundamentally different design lineages. The Intel Arc B390 is built on the Panther Lake chip using the Xe3-LPG architecture, part of the Arc Graphics-M (Panther Lake) generation. It is fabricated on a 3 nm process at Intel. The transistor count and die size for the Arc B390 are recorded as unknown. The RTX 5000 Ada Generation uses the AD102 chip with the Ada Lovelace architecture, part of the Workstation Ada generation. It is fabricated on a 5 nm process at TSMC, with 76,300 million transistors on a 609 mm² die, giving a transistor density of 125.3M per mm².

The compute pipelines are vastly different in scale. The Arc B390 has 1536 shading units, 48 texture mapping units, 24 raster output units, and 12 ray tracing cores. It has no recorded tensor cores. The RTX 5000 Ada Generation has 12800 shading units, 400 texture mapping units, 176 raster output units, 100 ray tracing cores, and 400 tensor cores. The RTX 5000 Ada has roughly 8.3 times the shading units and 8.3 times the raster output units of the Arc B390, and more than 8 times the ray tracing cores.

Clock behavior also differs. The Arc B390 runs at a base clock of 300 MHz and a boost clock of 2500 MHz. The RTX 5000 Ada Generation runs at a base clock of 1155 MHz and a boost clock of 2550 MHz. The RTX 5000 Ada has a higher base clock by 855 MHz, but the boost clocks are close, with the RTX 5000 Ada leading by only 50 MHz. The Arc B390's very low base clock suggests that it is designed to idle aggressively and ramp up under load, typical of integrated graphics.

Rasterization and texture throughput reflect the pipeline differences. The Arc B390 delivers a pixel rate of 60.00 GPixel/s and a texture rate of 120.0 GTexel/s. The RTX 5000 Ada Generation delivers a pixel rate of 448.8 GPixel/s, which is 7.48 times higher, and a texture rate of 1,020.0 GTexel/s, which is 8.5 times higher.

Compute precision handling is another point of divergence. The Arc B390 offers FP32 performance of 7.680 TFLOPS and FP16 performance of 15.36 TFLOPS at a 2:1 ratio, meaning it uses half the rate for FP32 as for FP16. The RTX 5000 Ada Generation offers 65.28 TFLOPS for both FP32 and FP16 at a 1:1 ratio, meaning it does not gain a throughput advantage from reduced precision. The RTX 5000 Ada's FP32 throughput is 8.5 times higher than the Arc B390's.

The API support is identical: both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs differ, with the Arc B390 using Portable Device Dependent outputs and the RTX 5000 Ada Generation offering 4x DisplayPort 1.4a.

Specification Differences

The two products differ across nearly every recorded specification field. The process node is 3 nm for the Intel Arc B390 and 5 nm for the NVIDIA RTX 5000 Ada Generation. The foundry is Intel for the former and TSMC for the latter. The RTX 5000 Ada has a recorded transistor count of 76,300 million and a die size of 609 mm², while the Arc B390 lists both as unknown.

Memory is a major differentiator. The Arc B390 uses System Shared memory with a System Shared bus width and System Dependent bandwidth. The RTX 5000 Ada Generation uses 32 GB of GDDR6 on a 256-bit bus with a bandwidth of 576.0 GB/s and a memory clock of 2250 MHz (18 Gbps effective).

Power and physical specifications differ sharply. The Arc B390 has a TDP of 80 W, an IGP slot width, no power connectors, and no suggested PSU. The RTX 5000 Ada Generation has a TDP of 250 W, a dual-slot width, one 16-pin power connector, and a suggested PSU of 600 W. The bus interface is IGP for the Arc B390 and PCIe 4.0 x16 for the RTX 5000 Ada Generation.

Dimensions are recorded only for the RTX 5000 Ada Generation, at 267 mm (10.5 inches) in length and 112 mm (4.4 inches) in height. The Arc B390 has no recorded dimensions, consistent with its integrated design. The RTX 5000 Ada Generation also has a recorded predecessor, Workstation Ampere, and successor, Blackwell PRO W, while the Arc B390 has neither.

Release dates differ by roughly two and a half years. The RTX 5000 Ada Generation was released on 2023-08-08, and the Arc B390 was released on 2026-01-26. Both are listed as Active in production status. Neither product has a recorded launch MSRP.

The compute specifications show the scale of the difference: shading units are 1536 versus 12800, TMUs are 48 versus 400, ROPs are 24 versus 176, RT cores are 12 versus 100, and tensor cores are absent versus 400. Pixel rate is 60.00 GPixel/s versus 448.8 GPixel/s, texture rate is 120.0 GTexel/s versus 1,020.0 GTexel/s, FP32 is 7.680 TFLOPS versus 65.28 TFLOPS, and FP16 is 15.36 TFLOPS (2:1) versus 65.28 TFLOPS (1:1).

The Verdict

The database places these two products at opposite ends of the GPU performance distribution. The Intel Arc B390 sits in the 9th percentile with an average score of 1482, competing with the NVIDIA GeForce GT 520MX, GeForce 800M, GeForce GT 625 OEM, and GeForce GT 710. The NVIDIA RTX 5000 Ada Generation sits in the 98th percentile with an average score of 184664, competing with the NVIDIA A100 SXM4 80 GB, A100 SXM4 40 GB, RTX PRO 5000 Blackwell, and GeForce RTX 4090 D. There is no overlap in their rival sets.

The Arc B390 is an integrated graphics part with an 80 W TDP, no power connectors, and system-shared memory. Its performance class, as measured by the database, is at the level of entry-level discrete GPUs from past generations. Its single recorded benchmark, 3DMark Steel Nomad DX12 at 1482, is its only data point. The product is designed for mobility and low power, not for high-end rendering or compute workloads.

The RTX 5000 Ada Generation is a dual-slot workstation card with a 250 W TDP, a 16-pin power connector, a 600 W suggested PSU, and 32 GB of dedicated GDDR6 memory. Its benchmark results, 175286 in Geekbench OpenCL and 194041 in Geekbench Vulkan, place it among the fastest GPUs in the database, within a few percent of the A100 SXM4 variants and the RTX PRO 5000 Blackwell. The 400 tensor cores and 100 ray tracing cores give it capabilities that the Arc B390 does not record at all.

The data supports a clear separation of use cases. The Arc B390 belongs in systems where power draw, physical footprint, and integration matter more than raw throughput. The RTX 5000 Ada Generation belongs in workstations where compute density, memory capacity, and measured performance at the 98th percentile are the priorities. Benchmark results indicate that no workload in the recorded data would place these two products in the same comparison bracket.
