Intel Arc B390 vs Intel Arc Pro B65 Comparison

Where Each One Wins

The benchmark data available for these two Intel GPUs is extremely limited, which makes the use-case split unusually stark. The Intel Arc B390 has one recorded benchmark result in the database: a 3DMark Steel Nomad DX12 score of 1482 points. The Intel Arc Pro B65 currently has no recorded benchmark scores at all, and its average benchmark score is listed as zero. This means the Arc B390 is the only one of the two that can be evaluated through direct performance measurements.

For the Arc B390, its single benchmark result places it at the 9th percentile among all GPUs in the database. That is a low overall standing, but the recorded data shows it is competitive with a specific cluster of older NVIDIA parts. The nearest rivals for the Arc B390 are the GeForce GT 520MX at 1463 points (1.3% behind), the GeForce 800M at 1460 points (1.5% behind), the GeForce GT 625 OEM at 1446 points (2.5% behind), and the GeForce GT 710 at 1443 points (2.7% behind). The Arc B390 leads all four of these by small margins, ranging from 1.3% to 2.7%.

The Arc Pro B65, by contrast, has no wins in the database because it has no benchmark entries. Its percentile ranking is 50, which reflects its position in the database structure rather than a measured performance result. The data cannot assign it any wins in head-to-head testing, as the head-to-head benchmark list between the two products is empty. The wins count for both products is zero.

What can be stated from the available measurements is that the Arc B390 is a low-power integrated graphics solution whose only measured score puts it in the entry-level segment, while the Arc Pro B65 is a professional workstation GPU with no measured scores recorded. The use-case split therefore comes down to what the specifications indicate: the Arc B390 is designed for portable devices, given its IGP bus interface, integrated form factor, and system-shared memory, while the Arc Pro B65 is a dual-slot add-in card with dedicated GDDR6 memory and four DisplayPort 2.1 outputs, aimed at professional display workloads.

The Verdict

The data supports a clear but conditional conclusion. For users who need a measured performance number, the Intel Arc B390 is the only option with a benchmark result on record. Its 1482 points in 3DMark Steel Nomad DX12 places it ahead of four NVIDIA rivals by narrow margins, but its 9th percentile standing indicates it sits at the low end of the overall GPU performance distribution.

The Intel Arc Pro B65, on the other hand, has no recorded benchmark scores, so the database cannot confirm its performance relative to any other GPU. Its specifications, however, indicate a substantially different class of hardware. The Arc Pro B65 uses a 5 nm TSMC process, has 19,600 million transistors on a 272 mm² die, and features 2560 shading units, 160 texture mapping units, 80 ROPs, and 20 ray tracing cores. Its FP32 compute is 12.29 TFLOPS, its texture rate is 384.0 GTexel/s, and its pixel rate is 192.0 GPixel/s. It has 32 GB of GDDR6 memory on a 256-bit bus with 608.0 GB/s of bandwidth.

The Arc B390, by comparison, has 1536 shading units, 48 TMUs, 24 ROPs, and 12 ray tracing cores. Its FP32 compute is 7.680 TFLOPS, its texture rate is 120.0 GTexel/s, and its pixel rate is 60.00 GPixel/s. Its memory is system-shared, meaning it uses the host system's memory rather than dedicated VRAM.

From the recorded data, the verdict is that the Arc B390 is the only one with a measurable benchmark presence, and it delivers a score that edges out several older NVIDIA parts by 1.3% to 2.7%. The Arc Pro B65 is the more capable part on paper, with roughly 60% more shading units, over three times the texture rate, over three times the pixel rate, and 60% higher FP32 compute. But without a recorded benchmark score, the database cannot offer a verified performance comparison. The Arc B390 is the part to choose when a measured result matters; the Arc Pro B65 is the part whose specifications promise far greater throughput, but whose benchmark data is absent.

Head-to-Head Benchmarks

The head-to-head benchmark list between the Intel Arc B390 and the Intel Arc Pro B65 is empty. There are no recorded tests where both products ran the same workload. The wins count for each product is zero, and there is no delta percentage to report between them.

The only benchmark score in the entire dataset belongs to the Arc B390. In 3DMark Steel Nomad DX12, it scored 1482 points. The nearest rival to that score is the NVIDIA GeForce GT 520MX at 1463 points, which is 1.3% behind. The GeForce 800M scores 1460 points, 1.5% behind. The GeForce GT 625 OEM scores 1446 points, 2.5% behind. The GeForce GT 710 scores 1443 points, 2.7% behind. These deltas are small, but they are consistent: the Arc B390 leads every one of its nearest rivals.

The Arc Pro B65 has no benchmark entries, no average score, and no nearest rivals listed. Its percentile rank of 50 is a database placeholder, not a measured result. The data cannot show any head-to-head wins for the Arc Pro B65 because there are no measurements to analyze.

The biggest win in either direction, therefore, is the Arc B390's measured lead over its closest rivals. A 1.3% advantage over the GT 520MX and a 2.7% advantage over the GT 710 represent the full extent of confirmed performance differences in the recorded data. The Arc Pro B65's superior specifications, such as its 12.29 TFLOPS FP32 versus the Arc B390's 7.680 TFLOPS, indicate that a head-to-head test would likely favor the Arc Pro B65, but the database does not contain that measurement.

Architecture Differences

The two GPUs come from different Intel architectures and different fabrication processes. The Intel Arc B390 uses the Xe3-LPG architecture, built on a 3 nm process node at Intel's own foundry. Its chip is codenamed Panther Lake and it belongs to the Arc Graphics-M (Panther Lake) generation. The Intel Arc Pro B65 uses the Xe2-HPG architecture, built on a 5 nm process node at TSMC. Its chip is codenamed BMG-G21 and it belongs to the Battlemage (Pro Series) generation.

The transistor count and die size differ substantially. The Arc Pro B65 has 19,600 million transistors on a 272 mm² die, with a transistor density of 72.1M per mm². The Arc B390's transistor count and die size are listed as unknown in the database.

The compute resources differ across every unit type. The Arc B390 has 1536 shading units, 48 texture mapping units, 24 ROPs, and 12 ray tracing cores. The Arc Pro B65 has 2560 shading units, 160 texture mapping units, 80 ROPs, and 20 ray tracing cores. Neither GPU lists tensor cores.

The FP32 and FP16 throughput figures reflect these differences. The Arc B390 delivers 7.680 TFLOPS of FP32 and 15.36 TFLOPS of FP16 (at a 2:1 ratio). The Arc Pro B65 delivers 12.29 TFLOPS of FP32 and 24.58 TFLOPS of FP16 (also at a 2:1 ratio). The pixel rate is 60.00 GPixel/s for the Arc B390 versus 192.0 GPixel/s for the Arc Pro B65.

The API support is identical: both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Specification Differences

The most significant specification difference is the memory subsystem. The Intel Arc B390 uses system-shared memory, with a system-shared size, type, bus width, and system-dependent bandwidth. The Intel Arc Pro B65 uses 32 GB of dedicated GDDR6 memory on a 256-bit bus, with a bandwidth of 608.0 GB/s. The Arc Pro B65's memory clock is listed as 2375 MHz with 19 Gbps effective.

Clock speeds differ as well. The Arc B390 has a base clock of 300 MHz and a boost clock of 2500 MHz. The Arc Pro B65 has a base clock of 2400 MHz and a boost clock of 2400 MHz, meaning it runs at a fixed clock.

Power and physical specifications diverge sharply. The Arc B390 has a TDP of 80 W, a slot width of IGP, no power connectors, and an IGP bus interface. The Arc Pro B65 has a TDP of 200 W, a dual-slot form factor, a single 8-pin power connector, a suggested PSU of 550 W, and a PCIe 5.0 x16 bus interface.

Display outputs also differ. The Arc B390's display outputs are listed as portable device dependent. The Arc Pro B65 has four DisplayPort 2.1 outputs.

Release dates differ by a few months. The Arc B390 was released on 2026-01-26, and the Arc Pro B65 was released on 2026-03-31. Both are listed as active production parts. Neither has a recorded launch MSRP in the database. Memory bandwidth is the largest single gap: 608.0 GB/s for the Arc Pro B65 versus system-dependent for the Arc B390. The Arc Pro B65 also has a much higher pixel rate at 192.0 GPixel/s versus 60.00 GPixel/s, and a higher texture rate at 384.0 GTexel/s versus 120.0 GTexel/s.
