Architecture Differences

The AMD Radeon RX 6550S is built on the RDNA 2.0 architecture, a mature design from the Radeon RX 6000 series. Its chip is Navi 24, manufactured on a 6 nm process at TSMC. The die measures 107 mm² and contains 5,400 million transistors, resulting in a transistor density of 50.5M per mm². The architecture uses a first-generation hardware ray tracing implementation with 16 dedicated ray tracing cores.

The Intel Arc Pro B370 uses the Xe3-LPG architecture, part of the Arc Graphics-WM generation built around Panther Lake. This GPU is manufactured on a 3 nm process at Intel's own foundry. The transistor count and die size are unknown in the database, but the process node advantage suggests a significantly more compact design. The Xe3-LPG architecture provides 10 ray tracing cores, fewer than the RX 6550S but paired with a higher shading unit count.

Clock behavior differs substantially between the two. The RX 6550S has a base clock of 2000 MHz, a game clock of 2170 MHz, and a boost clock of 2400 MHz. The Arc Pro B370 has an unusually low base clock of 300 MHz but matches the RX 6550S with a 2400 MHz boost clock. This wide clock range on the Intel part indicates aggressive power management, likely tied to its lower TDP. The Arc Pro B370's memory clock is system dependent, whereas the RX 6550S runs its GDDR6 at 2000 MHz with 16 Gbps effective speed.

Both GPUs are mobile-oriented, integrated parts with IGP slot width and no power connectors. The RX 6550S uses a PCIe 4.0 x4 bus interface, while the Arc Pro B370 uses an IGP bus interface. Display outputs for both are portable device dependent. The RX 6550S succeeds Polaris Mobile, and the Arc Pro B370 succeeds HD Graphics-WM.

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark results for these two GPUs. Both have an average benchmark score of 0 and no nearest rivals listed. Their percentile versus all GPUs is identical at 50, placing both in the middle of the performance distribution. Without direct measurement data, the comparison relies on specification-derived performance estimates.

The compute throughput comparison shows a clear advantage for the Intel part. The Arc Pro B370 delivers 6.144 TFLOPS of FP32 performance, which is 25% higher than the RX 6550S at 4.915 TFLOPS. The FP16 figures follow the same pattern: 12.29 TFLOPS for the Arc Pro B370 versus 9.830 TFLOPS for the RX 6550S, both using a 2:1 ratio.

Texture and pixel processing tell a different story. The RX 6550S has a texture rate of 153.6 GTexel/s, which is 60% higher than the Arc Pro B370's 96.00 GTexel/s. The pixel rate also favors AMD: 76.80 GPixel/s versus 48.00 GPixel/s, a 60% advantage. These differences stem from the resource allocation: the RX 6550S has 64 texture mapping units and 32 ROPs, while the Arc Pro B370 has 40 TMUs and 20 ROPs.

The shading unit count favors Intel at 1280 versus 1024 for AMD, a 25% difference that aligns with the FP32 compute gap. However, the AMD part's higher TMU and ROP counts give it an edge in fill-rate-bound workloads. The RX 6550S also has 16 ray tracing cores versus 10 on the Arc Pro B370, suggesting different ray tracing throughput characteristics despite the lack of benchmark data.

Memory bandwidth heavily favors AMD. The RX 6550S has 128.0 GB/s of dedicated bandwidth from its 4 GB GDDR6 pool, while the Arc Pro B370's bandwidth is system dependent. For workloads that rely on sustained memory access, the dedicated GDDR6 solution provides predictable performance. The Arc Pro B370's shared memory approach depends entirely on the host platform's memory configuration.

Where Each One Wins

The AMD Radeon RX 6550S wins in memory-intensive scenarios. Its dedicated 4 GB GDDR6 pool with 128.0 GB/s bandwidth provides consistent performance regardless of system memory configuration. The RX 6550S also dominates fill-rate workloads, with 60% higher texture rate and 60% higher pixel rate than the Arc Pro B370. These advantages point toward traditional rasterization tasks where texture sampling and pixel output are the primary bottlenecks. The 16 ray tracing cores, while not benchmarked, offer a higher ray tracing core count than the Intel part.

The Intel Arc Pro B370 wins in compute-bound workloads. Its 25% higher FP32 throughput and matching 25% advantage in shading units indicate stronger general-purpose compute performance. The 3 nm Intel process node delivers this performance at half the TDP: 25 W versus 50 W. For systems where power efficiency is critical, the Arc Pro B370 provides superior compute per watt based on the specification data. The lower TDP also suggests simpler thermal management requirements in compact portable devices.

The RX 6550S has the advantage of a longer production history, having been released on 2023-01-03, while the Arc Pro B370 is a newer part from 2026-01-26. The RX 6550S uses the PCIe 4.0 x4 interface, which allows it to function in systems with dedicated PCIe slots, whereas the Arc Pro B370 is limited to IGP integration.

The Verdict

The specification data shows two GPUs designed for different priorities. The AMD Radeon RX 6550S targets rasterization performance with its 64 TMUs, 32 ROPs, and dedicated GDDR6 memory. Its 153.6 GTexel/s texture rate and 76.80 GPixel/s pixel rate are the highest figures in this comparison, and the 128.0 GB/s dedicated bandwidth removes any dependency on system memory quality. The 50 W TDP reflects the cost of these dedicated resources.

The Intel Arc Pro B370 prioritizes compute efficiency. Its 6.144 TFLOPS FP32 throughput at 25 W TDP represents a compute-per-watt ratio that the RX 6550S cannot match, given the RX 6550S delivers 4.915 TFLOPS at double the power draw. The 1280 shading units and newer 3 nm process give it a clear edge in shader-heavy workloads. However, the system shared memory design makes its real-world bandwidth dependent on the host platform.

For applications that involve heavy texture sampling, pixel fill, or ray tracing core counts, the RX 6550S provides the more capable feature set on paper. For compute-oriented tasks where FP32 throughput and power efficiency matter more than memory bandwidth, the Arc Pro B370 holds the advantage. The absence of recorded benchmark results means these conclusions derive from specification analysis rather than measured performance. The equal 50th percentile ranking for both GPUs in the database suggests they occupy a similar overall performance tier, but the specification differences indicate they will respond very differently to various workload types.
