Intel Arc B390 is an integrated graphics processor built on Intel’s 3 nm Panther Lake process, using the Xe3-LPG architecture within the Arc Graphics-M (Panther Lake) generation. The data places this part in the 50th percentile of all GPUs, indicating a median position in the overall performance distribution, with its benchmark scores reflecting a design aimed at mainstream mobile and compact systems.
Benchmark Performance
The Intel Arc B390’s compute specifications establish a clear performance baseline. The GPU delivers 7.680 TFLOPS of FP32 throughput, with FP16 performance reaching 15.36 TFLOPS via a 2:1 ratio. Texture fill is rated at 120.0 GTexel/s, while pixel throughput sits at 60.00 GPixel/s. These figures, derived from 1536 shading units, 48 TMUs, and 24 ROPs, suggest balanced execution for both shader-heavy workloads and texture-bound scenarios. The 50th percentile ranking means the B390 sits exactly at the median of the benchmark database, outperforming half of all tracked GPUs while trailing the other half.
Clock behavior shows a base frequency of 300 MHz and a boost clock of 2500 MHz, a wide dynamic range that allows the chip to idle efficiently and ramp sharply under load. The memory subsystem is entirely system-dependent — size, type, bus width, and bandwidth are all marked as “System Shared” or “System Dependent,” meaning the B390’s effective performance will vary significantly based on the host platform’s RAM configuration. This is a critical caveat for interpreting scores: the 7.680 TFLOPS compute rate is fixed, but real-world throughput in memory-bound games will hinge on the shared memory bandwidth available from the host system.
In terms of raw output rates, the 60.00 GPixel/s pixel fill and 120.0 GTexel/s texture fill are modest figures compared to discrete solutions, but they are consistent with an integrated part designed for 1080p-class workloads. The FP32-to-pixel ratio (7.680 TFLOPS vs. 60.00 GPixel/s) indicates that compute-heavy operations like shader complexity will be handled more readily than pure rasterization throughput. The FP16 advantage, doubling to 15.36 TFLOPS, suggests that workloads leveraging reduced precision — common in some AI-assisted rendering or compute post-processing — can see a tangible uplift.
Who Should Consider It
Benchmark results indicate the Intel Arc B390 is best suited for users who prioritize efficiency and integration over absolute frame rates. The 80 W TDP, combined with an IGP slot width and no external power connectors, makes this a natural fit for thin-and-light laptops or compact desktops where thermal and power budgets are tight. The 50th percentile standing means it will handle esports titles and older AAA games at 1080p with reduced settings, but demanding modern releases will likely require significant graphical compromises.
For resolution targets, the data supports 1080p as the primary use case. The 60.00 GPixel/s pixel rate is sufficient for 1920×1080 output at moderate refresh rates, but attempting 1440p or 4K would strain the 24 ROPs and system-shared memory bandwidth. Users who play competitive shooters or MOBAs — where texture fill of 120.0 GTexel/s can keep up with lower-fidelity assets — will find the B390 adequate. Conversely, those seeking high-fidelity experiences in visually dense titles should look elsewhere, as the FP32 throughput and pixel fill are not competitive with even entry-level discrete GPUs in the database’s upper percentiles.
The 300 MHz base clock indicates excellent idle efficiency, while the 2500 MHz boost ensures responsiveness when needed. This dynamic range makes the B390 suitable for productivity tasks that involve occasional GPU acceleration, such as video encoding or light 3D rendering, without the power draw of a dedicated card. The absence of a suggested PSU rating reinforces its role in pre-configured systems where power delivery is already fixed. Ultimately, the data suggests a buyer who values portability and battery life over gaming headroom, or a secondary machine for light gaming and media consumption.
How It Compares
The FACT PACK lists no nearest rivals for the Intel Arc B390, which means the benchmark database currently has no direct comparison points within the specified proximity threshold. This absence is notable — it implies that the B390’s performance profile is either too unique or too newly added to match against other entries. Without deltaPct values or rival names, a positional analysis against specific competitors is not possible from the provided data.
Given the lack of nearest rivals, the 50th percentile is the sole reference marker. This ranking places the B390 in the middle of the entire GPU landscape, but the practical implications are limited because the percentile is not broken down by architecture, form factor, or generation. The B390’s integrated nature and system-shared memory mean that its effective standing could shift dramatically depending on the host system’s RAM speed and capacity — a factor that benchmark aggregation often normalizes or ignores.
The absence of rival data also means no direct speculation on relative strengths or weaknesses against specific parts. The B390’s 7.680 TFLOPS FP32 and 12 RT cores are fixed figures, but how they translate into game-by-game comparisons remains unquantified. Future database updates may populate the nearestRivals field, but as of the current FACT PACK, the B390 stands alone in the rankings, defined only by its absolute specifications and median percentile.

Ray Tracing and Feature Set
The Intel Arc B390 includes 12 RT cores, enabling hardware-accelerated ray tracing for supported titles. This is a dedicated set of cores within the Xe3-LPG architecture, distinct from the 1536 shading units. The presence of these cores means the B390 can handle ray-traced effects like shadows and reflections, though the overall compute budget of 7.680 TFLOPS will limit the complexity of ray-traced scenes. The 12 RT cores are a notable inclusion for an integrated GPU, as many IGP solutions omit dedicated ray tracing hardware entirely.
API support is comprehensive for modern gaming. The B390 supports DirectX 12 Ultimate with feature level 12_2, which includes hardware ray tracing and variable rate shading as part of the specification. OpenGL 4.6 is supported for legacy and professional applications, while Vulkan 1.4 provides low-level access for cross-platform titles and compute workloads. The DirectX 12 Ultimate certification ensures compatibility with the latest Windows games that require mesh shaders and other advanced features.
The feature set is rounded out by the 3 nm process node and Intel’s foundry production. The 80 W TDP and IGP form factor mean the B390 is not designed for standalone upgrade paths, but its integration into Panther Lake systems offers a baseline feature set that includes modern rendering APIs and dedicated ray tracing cores. The absence of a dedicated tensor core count in the FACT PACK means AI-accelerated features like DLSS-style upscaling are unquantified, though the FP16 throughput of 15.36 TFLOPS could support some compute-based enhancements. The display outputs are marked as portable-device dependent, reinforcing the mobile-centric design of this part.
