AMD Ryzen Z2 Extreme GPU vs Intel Arc Pro B390 Comparison

The AMD Ryzen Z2 Extreme GPU and Intel Arc Pro B390 represent two very different approaches to integrated graphics. The AMD part is a mature, shipping product built on a proven architecture, while the Intel part is a newer design aimed at a different segment. The recorded data shows a stark contrast in their positioning, with the AMD component having a measurable benchmark score, while the Intel component has no recorded benchmark results in the database. This analysis relies strictly on the available specifications and the single benchmark score for the AMD processor.

Where Each One Wins

The AMD Ryzen Z2 Extreme GPU currently holds the only recorded performance data point. Its average benchmark score of 516 in the 3DMark Steel Nomad DX12 test places it in the 1st percentile of all GPUs. This figure, while modest, indicates that it is a functional entry-level graphics solution capable of running the benchmark. The Intel Arc Pro B390, by contrast, has an average benchmark score of 0, which means it has no validated performance data in the database. The Intel part is listed in the 50th percentile of all GPUs, but this is based on its specifications rather than any measured score.

The AMD unit wins decisively in the category of available performance evidence. It has a concrete score, a fully populated specification sheet, and a known production status. The Intel Arc Pro B390 wins in the category of raw theoretical specifications, offering a higher FP32 throughput of 7.680 TFLOPS compared to the AMD's 5.530 TFLOPS. However, without a benchmark result, this theoretical advantage cannot be confirmed in practice.

The AMD part also wins on power efficiency in terms of the performance-to-power ratio that can be derived from the data. It delivers its 5.530 TFLOPS within a 28 W TDP, while the Intel part consumes 80 W for its 7.680 TFLOPS. The AMD component achieves a higher ratio of compute per watt, suggesting it is the more efficient solution in the available data.

Architecture Differences

The two GPUs use fundamentally different architectures and manufacturing processes. The AMD Ryzen Z2 Extreme GPU is built on the Strix Point chip, utilizing the RDNA 3.5 architecture. It is fabricated on a 4 nm process by TSMC, containing 34,000 million transistors on a 233 mm² die. This results in a transistor density of 145.9 million transistors per square millimeter.

The Intel Arc Pro B390 uses the Panther Lake chip with the Xe3-LPG architecture, fabricated on a 3 nm process by Intel. Its transistor count and die size are listed as unknown in the database, so no density figure can be calculated. The AMD part uses a dedicated 16 GB LPDDR5X memory pool with a 128-bit bus, providing 128.0 GB/s of bandwidth. The Intel part uses System Shared memory, with its bus width and bandwidth listed as System Dependent.

The compute configurations differ significantly. The AMD GPU has 1024 shading units, 64 texture mapping units, and 48 render output units. It also includes 16 ray tracing cores. The Intel GPU has a higher count of 1536 shading units but fewer TMUs at 48 and fewer ROPs at 24. It includes 12 ray tracing cores. The AMD part has a higher pixel rate of 129.6 GPixel/s versus the Intel's 60.00 GPixel/s, and a higher texture rate of 172.8 GTexel/s versus 120.0 GTexel/s. The Intel part has a higher FP32 compute rating, but the AMD part has a higher pixel fill rate, which can matter for certain rendering workloads.

The FP16 compute differs as well. The AMD GPU delivers 5.530 TFLOPS at FP16 with a 1:1 ratio to FP32, meaning there is no dedicated half-precision boost. The Intel GPU delivers 15.36 TFLOPS at FP16 with a 2:1 ratio, indicating a dedicated path for half-precision math that doubles its throughput.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between these two GPUs. The AMD Ryzen Z2 Extreme GPU has one recorded 3DMark Steel Nomad DX12 score of 516. The Intel Arc Pro B390 has no benchmark entries at all, with an average score of 0.

The AMD part's nearest rivals in the database provide context for its performance. It sits 3.4% behind the Intel HD Graphics P4000, which scores 534, and 3.7% behind the AMD Radeon HD 6870, which scores 536. It sits 6.6% ahead of the AMD Radeon HD 6750M, which scores 484, and 9.3% behind the AMD Radeon HD 6770M, which scores 569. These deltas place the AMD GPU in a narrow performance band among older discrete and integrated parts.

The Intel Arc Pro B390 has no nearest rivals listed, which further confirms the absence of measured performance data. Its 50th percentile ranking is a speculative placement based on its specifications, not on observed results. The FP32 throughput difference suggests the Intel part could outperform the AMD part if its architectural efficiency matches its compute rating, but the data does not confirm this.

The Verdict

The data indicates that the AMD Ryzen Z2 Extreme GPU is a verified, low-power integrated solution with a modest but confirmed performance profile. Its 516 score in 3DMark Steel Nomad DX12, its 1st percentile ranking, and its 28 W TDP make it a known quantity for light graphics workloads. Its nearest rivals, all scoring between 484 and 569, show that it operates in a narrow band of older hardware performance.

The Intel Arc Pro B390 presents a theoretical alternative. Its higher FP32 throughput of 7.680 TFLOPS and its FP16 capability of 15.36 TFLOPS suggest a more capable compute engine on paper. Its 80 W TDP and System Shared memory indicate a design intended for portable devices, as its display outputs are listed as Portable Device Dependent. Its 50th percentile ranking implies a higher specification placement, but the complete absence of benchmark results means this cannot be validated.

The AMD part is the only one with measured performance. The Intel part is the only one with a higher theoretical compute ceiling. The two do not overlap in the data, so a direct comparison of real-world speed is not possible. The AMD Ryzen Z2 Extreme GPU is the choice for confirmed, low-power graphics. The Intel Arc Pro B390 is a specification-based prospect with unproven performance.
