Intel Arc A530M vs Intel Arc Pro B390 Comparison

Intel Arc A530M vs Intel Arc Pro B390

The Intel Arc A530M and Intel Arc Pro B390 occupy two very different positions in the recorded database. The A530M is a mature mobile part with a measured average benchmark score of 46614, placing it in the 85th percentile of all GPUs. The Pro B390, by contrast, has no recorded benchmark scores, sits at the 50th percentile, and carries an average benchmark score of zero. This means the data can only describe the A530M through direct performance measurements, while the Pro B390 must be analyzed through its architectural specifications alone. The A530M is a discrete graphics solution with dedicated GDDR6 memory, while the Pro B390 is an integrated processor graphics solution that shares system memory. These are fundamentally different products that happen to share the same manufacturer and similar shading unit counts.

The Verdict

The database shows a clear division of roles. The Intel Arc A530M is the only one of the two with measurable performance data, and its 85th percentile ranking indicates it sits comfortably above the median GPU in the database. Its average benchmark score of 46614 places it directly alongside the AMD Radeon RX 5600M, which scores 46601, a difference of zero percent. It also edges out the NVIDIA RTX A2000 by 1.2 percent (46043) and the NVIDIA RTX 5880 Ada Generation by 1.4 percent (45972). The nearest rival on the other side is the AMD Radeon RX 6550M at 46702, which leads the A530M by 0.2 percent. These deltas are small, so the A530M is essentially performance-equivalent to a tight cluster of mid-range discrete GPUs.

The Intel Arc Pro B390 has no benchmark entries in the database, so its average score is recorded as zero and its percentile is 50. It cannot be compared numerically to the A530M or any other GPU. What the data does show is that the Pro B390 is built on a newer architecture and a smaller process node, and it delivers a higher theoretical compute throughput. Its FP32 figure of 7.680 TFLOPS is nearly double the A530M's 3.994 TFLOPS. However, it is an integrated part with system-shared memory, so its real-world performance depends entirely on the host platform's memory configuration, which the database records as System Dependent.

The data implies that a user who needs a known, measurable discrete GPU should look at the A530M. It has recorded scores, a proven place in the 85th percentile, and direct comparisons to four named rivals. A user who needs a modern integrated GPU with high theoretical compute and low power integration should consider the Pro B390, but the database provides no evidence of its actual benchmark performance.

Architecture Differences

The two GPUs come from different architectural generations. The Intel Arc A530M uses the DG2-256 chip built on the Xe-HPG architecture, belonging to the Alchemist generation within the Arc 5 Mobile family. It is fabricated on a 6 nm process at TSMC, with 11,500 million transistors on a 269 mm² die, giving a transistor density of 42.8 million transistors per square millimeter. The Intel Arc Pro B390 uses the Panther Lake chip built on the Xe3-LPG architecture, belonging to the Arc Graphics-WM generation. It is fabricated on a 3 nm process at Intel, with transistor count and die size both recorded as unknown.

The process node difference is significant: 6 nm from TSMC versus 3 nm from Intel. The Pro B390 also lists a predecessor, HD Graphics-WM, while the A530M lists none. The A530M was released on 2023-07-31, while the Pro B390 has a release date of 2026-01-26, a gap of roughly two and a half years. Both are marked as Active production status.

Despite the architectural gap, both GPUs share identical shading unit counts of 1536 and identical ray tracing core counts of 12. Both support the same API set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The A530M's Xe-HPG architecture is a discrete design with its own memory interface, while the Pro B390's Xe3-LPG architecture is an integrated design with no dedicated memory bus listed. The memory system is the largest architectural divergence: the A530M uses 8 GB of GDDR6 over a 128 bit bus with 224.0 GB/s of bandwidth, while the Pro B390 uses System Shared memory with a System Shared bus width and System Dependent bandwidth.

Head-to-Head Benchmarks

There are no head-to-head benchmark entries in the database for these two GPUs, so no direct comparison scores exist. The A530M has two recorded benchmark results: a Geekbench OpenCL score of 49735 and a Geekbench Vulkan score of 43492. The Pro B390 has no benchmark results whatsoever. This absence of data is itself a finding: the database cannot confirm how the Pro B390 performs under any workload.

The A530M's average benchmark score of 46614 is the central reference point. Its nearest rival list shows a tight grouping. The AMD Radeon RX 5600M matches it exactly at 46601 with a delta of zero percent. The AMD Radeon RX 6550M leads by 0.2 percent with a score of 46702. The NVIDIA RTX A2000 trails by 1.2 percent at 46043, and the NVIDIA RTX 5880 Ada Generation trails by 1.4 percent at 45972. These numbers indicate that the A530M performs in a narrow band around 46,000 to 46,700 points, with no rival in its immediate vicinity exceeding a two percent spread.

The Pro B390's average score of zero and 50th percentile placement mean it cannot be positioned relative to any rival. It has no nearest rivals listed. Any statement about its performance relative to the A530M would be unsupported by the recorded data. The only quantifiable comparison available is theoretical throughput, where the Pro B390 leads.

Specification Differences

The two parts differ across nearly every hardware specification except shading units, RT cores, API support, slot width, and production status.

The A530M has a base clock of 900 MHz and a boost clock of 1300 MHz, with memory running at 1750 MHz and 14 Gbps effective. The Pro B390 has a base clock of 300 MHz and a boost clock of 2500 MHz, with memory listed as System Shared. The Pro B390's boost clock is substantially higher, 2500 MHz versus 1300 MHz, while its base clock is lower, 300 MHz versus 900 MHz. This suggests a design that idles low and boosts aggressively, typical of an integrated part, though the database does not state this explicitly.

The A530M's memory configuration is fully specified: 8 GB of GDDR6, 128 bit bus, 224.0 GB/s bandwidth. The Pro B390's memory configuration is entirely System Shared, with bandwidth marked System Dependent. This is the single most important functional difference. The A530M has guaranteed memory bandwidth; the Pro B390 does not.

Texture and pixel throughput also differ. The A530M has 96 texture mapping units and 48 render output units, producing a pixel rate of 62.40 GPixel/s and a texture rate of 124.8 GTexel/s. The Pro B390 has 48 texture mapping units and 24 render output units, producing a pixel rate of 60.00 GPixel/s and a texture rate of 120.0 GTexel/s. The A530M leads in both rates, despite the Pro B390's higher compute figures.

Compute throughput favors the Pro B390. The A530M delivers 3.994 TFLOPS FP32 and 7.987 TFLOPS FP16. The Pro B390 delivers 7.680 TFLOPS FP32 and 15.36 TFLOPS FP16. This is the only metric where the Pro B390 roughly doubles the A530M. The power draw also differs: the A530M has a TDP of 65 W, while the Pro B390 has a TDP of 80 W. The Pro B390 lists no power connectors, while the A530M lists none as well, but the Pro B390 explicitly states None.

The A530M uses a PCIe 4.0 x8 bus interface, while the Pro B390 uses an IGP bus interface. Both are listed with slot width IGP, and both have display outputs marked Portable Device Dependent. Neither has a launch MSRP recorded, so no pricing information can be stated.

Where Each One Wins

The Arc A530M wins in every measured and directly quantifiable category. It has a recorded average benchmark score of 46614, a Geekbench OpenCL score of 49735, and a Geekbench Vulkan score of 43492. It has a higher pixel rate of 62.40 GPixel/s versus 60.00 GPixel/s, and a higher texture rate of 124.8 GTexel/s versus 120.0 GTexel/s. It has more texture mapping units (96 versus 48) and more render output units (48 versus 24). It has dedicated 8 GB GDDR6 memory with 224.0 GB/s bandwidth, which removes any dependency on host system memory. It also has a lower TDP of 65 W versus 80 W. Its nearest rival comparisons place it in a known performance band, and its 85th percentile ranking confirms it outranks the majority of GPUs in the database.

The Arc Pro B390 wins in architectural modernity and theoretical compute. It uses a newer Xe3-LPG architecture on a 3 nm Intel process, compared to the older Xe-HPG architecture on a 6 nm TSMC process. It delivers 7.680 TFLOPS FP32, roughly 92 percent higher than the A530M's 3.994 TFLOPS. Its FP16 output of 15.36 TFLOPS is similarly about 92 percent higher than 7.987 TFLOPS. It has a much higher boost clock of 2500 MHz versus 1300 MHz. It is an integrated part with no power connectors and an IGP bus interface, meaning it can be deployed in systems where a discrete GPU is not an option. Its release date of 2026-01-26 makes it the newer product by several years, and it lists a predecessor, HD Graphics-WM, indicating a direct lineage in the integrated graphics space.

The data does not show a single overall winner because the two products serve different hardware classes. The A530M is the only one with benchmark evidence, and it performs in a competitive cluster around the RX 5600M and RX 6550M. The Pro B390 has no measured evidence, so its higher theoretical compute cannot be verified through the database. A user choosing between them would be selecting between a proven discrete GPU with dedicated memory and an unproven integrated GPU with higher compute ceilings and complete dependence on system memory.
