AMD Ryzen Z2 GPU vs Intel Arc Pro B390 Comparison

Head-to-Head Benchmarks

The recorded database contains no direct benchmark scores for either the AMD Ryzen Z2 GPU or the Intel Arc Pro B390. Both entries show an average benchmark score of 0, and the head-to-head comparison table is empty. The win count for each GPU is also zero, meaning there is no measured performance data available to determine a definitive leader in computational workloads.

Both GPUs sit at the 50th percentile against all GPUs in the database, which places them in the middle of the overall performance distribution. Without specific benchmark results, the percentile ranking indicates that neither GPU has demonstrated an advantage over the other in the recorded measurements. The lack of scores means any claims about relative performance must rely on architectural specifications rather than empirical testing.

The absence of benchmark data does not diminish the value of the specification comparison. The recorded information shows that the AMD Ryzen Z2 GPU delivers 8.294 TFLOPS of FP32 compute, while the Intel Arc Pro B390 delivers 7.680 TFLOPS. This difference is modest, roughly 8% in favor of the AMD part based on the raw numbers. In FP16 workloads, the Intel GPU takes a clear lead with 15.36 TFLOPS, compared to 8.294 TFLOPS for the AMD GPU, which executes FP16 at a 1:1 ratio with FP32.

Pixel throughput favors the AMD GPU, which records 86.40 GPixel/s versus 60.00 GPixel/s for the Intel part. Texture throughput is closer, with the AMD GPU at 129.6 GTexel/s and the Intel GPU at 120.0 GTexel/s. These figures suggest that the AMD GPU has an edge in rasterization-heavy scenes, while the Intel GPU offers superior half-precision compute performance.

Architecture Differences

The two GPUs come from different architectural lineages. The AMD Ryzen Z2 GPU uses the RDNA 3.0 architecture, built on the Hawk Point chip, and belongs to the Console GPU generation from AMD. The Intel Arc Pro B390 uses the Xe3-LPG architecture, built on the Panther Lake chip, and belongs to the Arc Graphics-WM generation from Intel.

Manufacturing processes differ significantly. The AMD GPU is fabricated on a 4 nm process at TSMC, while the Intel GPU uses a 3 nm process at Intel's own foundry. The AMD chip contains 25,390 million transistors on a die size of 178 mm², giving a transistor density of 142.6 million transistors per square millimeter. Intel has not disclosed the transistor count or die size for the Arc Pro B390 in the database.

Core configurations reveal different design philosophies. The AMD GPU has 768 shading units, 48 texture mapping units, and 32 render output units. The Intel GPU has double the shading units at 1536, the same 48 TMUs, and fewer ROPs at 24. Both GPUs have 12 ray tracing cores, a direct architectural parallel. The Intel GPU's higher shading unit count does not translate into higher FP32 throughput due to its lower clock speeds.

Clock speeds diverge sharply. The AMD GPU runs at a base clock of 800 MHz and boosts to 2700 MHz. The Intel GPU has a base clock of 300 MHz and boosts to 2500 MHz. The AMD GPU's higher clocks contribute to its pixel rate advantage, while the Intel GPU's wider shader array powers its FP16 throughput.

Memory configurations are fundamentally different. The AMD GPU uses 16 GB of LPDDR5X memory on a 128-bit bus, delivering 119.9 GB/s of bandwidth. Memory clocks run at 937 MHz, which translates to 7.5 Gbps effective. The Intel GPU relies on system shared memory, with the type, bus width, and bandwidth all marked as system dependent. This means the Intel GPU's memory performance depends entirely on the host platform.

Power requirements show a major distinction. The AMD GPU has a TDP of 28 W, while the Intel GPU has a TDP of 80 W. Neither GPU requires external power connectors. The Intel GPU is classified as an integrated graphics processor (IGP) with a slot width of IGP and a bus interface of IGP. The AMD GPU has no recorded slot width or bus interface information.

Display outputs also differ. The AMD GPU provides a single USB Type-C output. The Intel GPU's display outputs are portable device dependent, meaning they vary based on the system it is integrated into.

Both GPUs support identical API levels: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. This parity means software compatibility is equivalent across the two parts.

Release timing separates the products. The AMD Ryzen Z2 GPU was released on 2024-12-31, while the Intel Arc Pro B390 has a release date of 2026-01-26. The Intel GPU has a listed predecessor, HD Graphics-WM, while the AMD GPU has no predecessor or successor recorded in the database. Both GPUs are marked as active production status.

The Verdict

The data indicates that neither GPU has a benchmark-derived performance advantage, as both share the same 50th percentile ranking and have no recorded scores. The choice between them depends on the workload and system context.

For rasterization-focused tasks, the AMD Ryzen Z2 GPU presents a stronger profile. Its pixel rate of 86.40 GPixel/s exceeds the Intel GPU's 60.00 GPixel/s, and its texture rate of 129.6 GTexel/s beats the Intel GPU's 120.0 GTexel/s. The AMD GPU also has more ROPs, 32 versus 24, which supports higher fill rates. Its 28 W TDP makes it suitable for power-constrained environments, and its dedicated 16 GB LPDDR5X memory with 119.9 GB/s bandwidth provides predictable memory performance.

For compute-heavy workloads that leverage half precision, the Intel Arc Pro B390 offers a distinct advantage. Its FP16 throughput of 15.36 TFLOPS nearly doubles the AMD GPU's 8.294 TFLOPS. The Intel GPU's 1536 shading units provide a wider execution array, even at lower clock speeds. The system shared memory model means the Intel GPU can scale with the host's memory capacity, though bandwidth remains system dependent.

The Intel GPU's 80 W TDP is nearly three times that of the AMD GPU, which may matter in compact or battery-powered systems. The AMD GPU's single USB Type-C display output contrasts with the Intel GPU's portable device dependent outputs, which reflects their different target platforms. The AMD GPU belongs to a console GPU generation and was released earlier, on 2024-12-31, while the Intel GPU targets the Arc Graphics-WM segment with a later release date of 2026-01-26.

The architectural split is clear: AMD concentrates on higher clocks and dedicated memory for consistent raster performance, while Intel relies on a wider shader array and process node advantage for compute throughput. The 3 nm Intel process versus the 4 nm TSMC process gives Intel a manufacturing edge, but the lack of disclosed transistor and die size data prevents a density comparison.

Both GPUs support the same API feature set, so software compatibility is not a differentiator. The AMD GPU's higher FP32 and pixel rates suggest it is better suited for traditional graphics pipelines, while the Intel GPU's FP16 capability points toward machine learning and compute applications that use reduced precision.

The absence of benchmark scores means these conclusions rest on specification analysis rather than measured results. The database shows both GPUs at the 50th percentile, which is a neutral position, but the underlying hardware characteristics provide clear directional guidance. The AMD Ryzen Z2 GPU is the more efficient rasterizer with dedicated memory, and the Intel Arc Pro B390 is the higher-throughput compute part with a wider shader array and newer process node.
