AMD Radeon RX 9050 OEM vs Intel Arc B370 Comparison

AMD Radeon RX 9050 OEM and Intel Arc B370 occupy very different positions in the recorded data. The RX 9050 OEM is a discrete desktop add-in board from the Radeon RX 9000 series, built on the Navi 44 chip with RDNA 4.0 architecture. The Arc B370 is an integrated graphics processor within Intel's Panther Lake mobile platform, using Xe3-LPG architecture. The database shows the RX 9050 OEM at the 50th percentile among all GPUs, while the Arc B370 sits at the 5th percentile. This gap in percentile ranking, combined with their divergent specifications, indicates these products serve entirely separate use cases despite sharing API support.

Where Each One Wins

The AMD Radeon RX 9050 OEM wins in raw rasterization throughput. Its shading units total 1024, compared to 1280 on the Arc B370, yet the AMD part delivers 10.65 TFLOPS of FP32 compute against the Intel part's 6.144 TFLOPS. The RX 9050 OEM also holds a substantial advantage in pixel throughput at 166.4 GPixel/s versus 48.00 GPixel/s, and in texture rate at 166.4 GTexel/s versus 96.00 GTexel/s. These figures indicate the RX 9050 OEM handles high-resolution rendering and texture-heavy workloads with significantly more headroom.

The RX 9050 OEM wins in memory bandwidth. It uses 4 GB of dedicated GDDR6 memory on a 64-bit bus, delivering 144.0 GB/s of bandwidth. The Arc B370 relies on System Shared memory, with bandwidth listed as System Dependent, meaning its performance scales with the host platform's memory configuration rather than a fixed dedicated pool. For applications sensitive to memory throughput, the dedicated VRAM of the RX 9050 OEM provides a predictable advantage.

The Arc B370 wins in power efficiency. Its TDP is 25 W, versus 92 W for the RX 9050 OEM. The Arc B370 also requires no power connectors and uses an IGP slot interface, making it suitable for compact portable devices where thermal and power budgets are constrained. The RX 9050 OEM, by contrast, needs a dual-slot cooler, a single 8-pin power connector, and a 250 W suggested PSU.

The Arc B370 wins in FP16 compute. It delivers 12.29 TFLOPS with a 2:1 ratio, exceeding the RX 9050 OEM's 10.65 TFLOPS which runs at a 1:1 ratio. This makes the Intel part more capable in workloads that leverage half-precision arithmetic, such as certain AI inference tasks, even though its FP32 throughput is lower.

Architecture Differences

The RX 9050 OEM uses the Navi 44 chip fabricated on a 4 nm process at TSMC, containing 29,700 million transistors on a 199 mm² die, resulting in a transistor density of 149.2M per mm². The Arc B370 uses the Panther Lake chip on a 3 nm process at Intel, though its transistor count and die size are recorded as unknown. The manufacturing processes differ by foundry and node, with the Intel part using the smaller 3 nm node.

The RX 9050 OEM has 64 texture mapping units and 64 ROPs, while the Arc B370 has 40 TMUs and 20 ROPs. The RX 9050 OEM carries 16 ray tracing cores, the Arc B370 has 10. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RX 9050 OEM uses a PCIe 5.0 x16 bus interface, whereas the Arc B370 is an IGP with no independent bus interface. The Arc B370 operates with a base clock of 300 MHz and a boost clock of 2400 MHz; the RX 9050 OEM has a base clock of 1330 MHz, a game clock of 1920 MHz, and a boost clock of 2600 MHz.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between the RX 9050 OEM and the Arc B370. The wins counter shows zero for both sides in head-to-head testing. However, the Arc B370 has a single recorded benchmark score: 1184 in 3dmark_3dmark_steel_nomad_dx12. This places it at the 5th percentile among all GPUs. Its nearest rivals in that benchmark are ATI Mobility Radeon HD 5570 with an average score of 1186 and a delta of -0.2%, ATI Radeon HD 5770 with 1190 and -0.5%, AMD Radeon HD 7650M with 1192 and -0.7%, and AMD FirePro M2000 with 1168 and 1.4%. These deltas are all within roughly one and a half percent, indicating the Arc B370's performance clusters tightly with older discrete and mobile GPUs from the HD 5000 and HD 7000 generations.

The RX 9050 OEM has no recorded benchmark scores, so its measured performance cannot be directly compared to the Arc B370 or any other GPU in the database. Its 50th percentile ranking is based on its overall standing among all GPUs, not on a specific test result. Given the specification data, the RX 9050 OEM's FP32 throughput of 10.65 TFLOPS is 73% higher than the Arc B370's 6.144 TFLOPS. Its pixel rate of 166.4 GPixel/s is more than triple the Arc B370's 48.00 GPixel/s. Its texture rate of 166.4 GTexel/s is 73% higher than 96.00 GTexel/s. These compute and throughput advantages suggest the RX 9050 OEM would score considerably higher in rasterization-focused benchmarks, though no direct measurement exists in the database to confirm this.

The Verdict

The data indicates the RX 9050 OEM is the choice for workloads that demand high rasterization throughput, dedicated memory bandwidth, and ray tracing capacity. Its 10.65 TFLOPS FP32, 166.4 GPixel/s pixel rate, 144.0 GB/s dedicated bandwidth, and 16 ray tracing cores position it for gaming and content creation on a desktop platform with a PCIe 5.0 x16 slot and a 250 W suggested PSU. Its 92 W TDP and dual-slot cooler require a conventional desktop chassis with an 8-pin power connector.

The Arc B370 is the choice for power-constrained portable devices. Its 25 W TDP, IGP form factor, and no power connector requirement make it suitable for thin-and-light laptops where the RX 9050 OEM physically cannot fit. Its FP16 throughput of 12.29 TFLOPS exceeds the AMD part, giving it an edge in half-precision compute tasks. However, its benchmark score of 1184 in 3DMark Steel Nomad DX12 and its 5th percentile ranking show it performs in the range of much older GPUs, with nearest rivals from the ATI HD 5000 and HD 7000 generations all within 1.4% of its score. Users needing a discrete GPU for demanding rendering should select the RX 9050 OEM; users needing integrated graphics for a low-power mobile platform should select the Arc B370. The two products do not compete in the same market segment, as confirmed by their form factors, power requirements, and memory architectures.
