AMD Radeon RX 9050 vs Intel Arc Pro B390 Comparison

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark results between the AMD Radeon RX 9050 and the Intel Arc Pro B390. Neither unit has an average benchmark score recorded, and both sit at the 50th percentile among all GPUs in the database. This means the two cards are positioned at the same performance tier in the aggregate rankings, but the lack of direct comparison scores prevents a definitive statement on which unit holds a measurable performance advantage in any specific workload.

What the data does provide is a set of compute and throughput figures that can be examined side by side. The AMD Radeon RX 9050 delivers 10.65 TFLOPS of FP32 compute, while the Intel Arc Pro B390 delivers 7.680 TFLOPS. That places the AMD part approximately 39% higher in single-precision floating-point throughput. In FP16, the AMD card again outputs 10.65 TFLOPS with a 1:1 ratio, whereas the Intel card outputs 15.36 TFLOPS with a 2:1 ratio, meaning Intel has a notable lead in half-precision work. The pixel rate favors AMD at 166.4 GPixel/s versus Intel’s 60.00 GPixel/s, and the texture rate also favors AMD at 166.4 GTexel/s versus Intel’s 120.0 GTexel/s.

Memory bandwidth differs substantially. The AMD Radeon RX 9050 uses 8 GB of GDDR6 over a 128-bit bus, yielding 288.0 GB/s of dedicated bandwidth. The Intel Arc Pro B390 uses system shared memory, with bandwidth listed as system dependent and a bus width that is also system shared. This means the AMD part has a fixed, dedicated memory pipeline, while the Intel part relies on whatever system memory configuration is present, which can vary by platform.

The shading unit count favors Intel, which has 1536 shading units versus AMD’s 1024. However, the AMD card has 64 texture mapping units and 64 raster operation pipelines, while the Intel card has 48 TMUs and 24 ROPs. The AMD part also includes 16 ray tracing cores, while the Intel part includes 12. Clock speeds show AMD boosting to 2600 MHz with a game clock of 1920 MHz and a base of 1330 MHz. Intel boosts to 2500 MHz but has a much lower base of 300 MHz, which suggests the Intel part is designed for variable power states in a portable or integrated context.

Without direct benchmark scores, the only clear numerical conclusion is that AMD leads in FP32, pixel fill, texture fill, and dedicated memory bandwidth, while Intel leads in FP16 throughput and shading unit count. The practical impact of those leads depends on the workload and the system memory architecture behind the Intel part.

Where Each One Wins

The AMD Radeon RX 9050 wins in scenarios that depend on dedicated memory bandwidth and high raster throughput. Its 288.0 GB/s of dedicated GDDR6 bandwidth is fixed and independent of system configuration, which matters for texture-heavy rendering and high-resolution framebuffer work. The pixel rate of 166.4 GPixel/s and texture rate of 166.4 GTexel/s are both roughly 39% higher than the Intel part’s pixel rate of 60.00 GPixel/s and texture rate of 120.0 GTexel/s. This makes the AMD card the stronger choice for conventional 3D rendering that relies on fill rate and memory latency.

The Intel Arc Pro B390 wins in half-precision compute tasks. Its FP16 output of 15.36 TFLOPS is approximately 44% higher than the AMD part’s 10.65 TFLOPS, and the 2:1 FP16 ratio indicates the Intel architecture is optimized for reduced-precision workloads. The higher shading unit count of 1536 also gives Intel an advantage in workloads that scale with shader occupancy rather than texture or ROP throughput. Integrated into a system with fast shared memory, the Intel part could be competitive for compute-heavy tasks that use FP16 math, such as certain machine learning inference or image processing pipelines.

The AMD card also wins on clock stability. A base clock of 1330 MHz and a game clock of 1920 MHz mean the AMD part maintains high frequency under sustained load. Intel’s base clock of 300 MHz with a boost of 2500 MHz suggests a wider frequency swing and a design that may spend more time at lower clocks during light workloads.

The Verdict

The data points to two different intended roles. The AMD Radeon RX 9050 is a discrete, dual-slot card with dedicated GDDR6 memory, a fixed 288.0 GB/s bandwidth, and higher raster throughput. It leads in FP32 compute at 10.65 TFLOPS, pixel fill at 166.4 GPixel/s, and texture fill at 166.4 GTexel/s. Its base clock of 1330 MHz and game clock of 1920 MHz indicate sustained performance under load. It also has more ROPs (64 versus 24) and more ray tracing cores (16 versus 12).

The Intel Arc Pro B390 is an integrated processor with shared memory, no power connectors, and a low 300 MHz base clock. It leads in FP16 compute at 15.36 TFLOPS and has more shading units at 1536. Its 80 W TDP and IGP form factor mean it draws power from the host system and requires no separate power supply.

For users who need a fixed, dedicated memory pipeline and high fill rates, the AMD Radeon RX 9050 is the clear choice based on the recorded specifications. For workloads that rely on half-precision math and higher shader occupancy, the Intel Arc Pro B390 offers a different capability profile, but its performance depends entirely on the host system’s shared memory configuration.

The percentile ranking places both at the 50th percentile among all GPUs, and neither has an average benchmark score. The absence of direct benchmark data means the verdict rests on specification analysis. The AMD part appears built for consistent discrete rendering performance. The Intel part appears built for integrated compute flexibility with variable memory performance. Users selecting between them should consider whether their workload favors dedicated bandwidth and raster throughput or half-precision compute and shader count.
