Q: When were these GPUs released?

A: The AMD Radeon RX 6550S was released on January 3, 2023, while the Intel Arc Graphics 4 Xe Mobile has a release date of January 26, 2026. Both are currently listed as Active in production status.

Architecture Differences

The AMD Radeon RX 6550S belongs to the Radeon RX 6000 series, specifically the Navi Mobile (RX 6000M) generation. It uses the RDNA 2.0 architecture built on a 6 nm process at TSMC. The die measures 107 mm² and contains 5,400 million transistors, yielding a transistor density of 50.5 million per square millimeter. The chip is identified as Navi 24, and its predecessor is Polaris Mobile.

The Intel Arc Graphics 4 Xe Mobile comes from the Arc Graphics-M (Panther Lake) generation and uses the Xe3-LPG architecture. It is fabricated on a 3 nm process at Intel's own foundry. The database does not record the transistor count, die size, or transistor density for this part. The chip is named Panther Lake, and there is no listed predecessor.

The compute resources differ substantially. The AMD GPU has 1024 shading units, 64 texture mapping units, 32 raster operation pipelines, and 16 ray tracing cores. The Intel GPU has half the shading units at 512, half the TMUs at 32, half the ROPs at 16, and only 4 ray tracing cores, which is a quarter of the AMD count. Neither GPU includes tensor cores.

Clock behavior also diverges. The AMD part runs at a 2000 MHz base clock and reaches 2400 MHz boost, with a game clock of 2170 MHz. The Intel part starts at just 300 MHz base, which is typical for an integrated GPU that scales up under load, and boosts to 2300 MHz. The AMD memory clock is 2000 MHz with 16 Gbps effective data rate, while the Intel memory clock is listed as system shared.

The memory architecture is fundamentally different. The Radeon RX 6550S has 4 GB of dedicated GDDR6 on a 64-bit bus, delivering 128.0 GB/s bandwidth. The Intel Arc Graphics 4 Xe Mobile uses system shared memory for both capacity and bus width, with bandwidth described as system dependent. This means the Intel GPU's memory performance is tied to the host platform's memory subsystem.

Power delivery differs as well. The AMD GPU has a 50 W TDP, while the Intel GPU has a 25 W TDP. Both are classified as integrated-class parts (IGP) with no external power connectors. The bus interface also differs: the AMD GPU uses PCIe 4.0 x4, while the Intel GPU uses an integrated graphics path (IGP).

Head-to-Head Benchmarks

The database does not contain direct head-to-head benchmark scores for this pair, so the comparison relies on the theoretical throughput figures and the recorded specification deltas. The raw compute numbers show a clear gap. The AMD Radeon RX 6550S delivers 4.915 TFLOPS of FP32 throughput, while the Intel Arc Graphics 4 Xe Mobile delivers 2.355 TFLOPS. That places the AMD part at roughly double the single-precision compute capacity. In FP16, the AMD GPU reaches 9.830 TFLOPS (2:1 ratio), and the Intel GPU reaches 4.710 TFLOPS (2:1 ratio), maintaining the same approximate 2:1 advantage.

The pixel and texture throughput figures reinforce the trend. The AMD GPU has a pixel rate of 76.80 GPixel/s and a texture rate of 153.6 GTexel/s. The Intel GPU has a pixel rate of 36.80 GPixel/s and a texture rate of 73.60 GTexel/s. Both figures for the Intel part are almost exactly half of the AMD numbers, which aligns with the halved ROP and TMU counts.

The memory bandwidth difference is more pronounced than the compute gap. The AMD GPU's dedicated GDDR6 provides 128.0 GB/s, while the Intel GPU's system shared memory bandwidth is system dependent, so no fixed number exists in the database. In practice, the AMD part's dedicated memory avoids contention with the CPU for memory access, which can be a meaningful advantage in bandwidth-sensitive workloads.

The clock speeds tell a nuanced story. The AMD GPU's 2000 MHz base clock is far above the Intel GPU's 300 MHz base clock, but the boost clocks are close: 2400 MHz versus 2300 MHz. The Intel part's low base clock suggests it idles at very low power and ramps up under load, while the AMD part maintains a higher floor. The AMD game clock of 2170 MHz sits between its base and boost figures, indicating sustained performance under gaming load.

The ray tracing hardware also differs by a factor of four. The AMD GPU has 16 RT cores, while the Intel GPU has 4 RT cores. This suggests the AMD part is better equipped for ray-traced workloads, though the database does not provide specific ray tracing benchmark scores.

The ROP and TMU counts are also doubled on the AMD side: 32 ROPs versus 16, and 64 TMUs versus 32. This directly impacts fill-rate-bound scenarios, such as high-resolution rasterization and texture-heavy scenes.

The Verdict

The recorded data shows that the AMD Radeon RX 6550S holds a substantial theoretical performance advantage over the Intel Arc Graphics 4 Xe Mobile in nearly every measured category. The FP32 compute throughput is 4.915 TFLOPS versus 2.355 TFLOPS, the pixel rate is 76.80 GPixel/s versus 36.80 GPixel/s, and the texture rate is 153.6 GTexel/s versus 73.60 GTexel/s. The AMD part also has double the shading units, TMUs, ROPs, and four times the RT cores.

The Intel part is not without its merits. It has a lower TDP of 25 W versus 50 W, which makes it suitable for thinner, more power-constrained portable devices. Its system shared memory model reduces component count and cost at the system level, though the database does not quantify that benefit. The Intel GPU is built on a smaller 3 nm process versus the AMD's 6 nm, which suggests better transistor-level efficiency, though the AMD part's transistor count is recorded while the Intel part's is unknown.

For users who prioritize raw graphics throughput, the AMD Radeon RX 6550S is the clear choice based on the data. The doubled shading units, TMUs, and ROPs, combined with dedicated GDDR6 memory, position it ahead in compute-heavy and memory-sensitive workloads. The 128.0 GB/s dedicated bandwidth is a fixed figure that does not depend on system configuration, unlike the Intel part's system dependent bandwidth.

For users who prioritize power efficiency and system integration, the Intel Arc Graphics 4 Xe Mobile offers a lower power envelope at 25 W and uses system shared memory, which simplifies the system design. Its 3 nm process node is more advanced than the AMD's 6 nm node, potentially offering better power-per-transistor characteristics, though the database does not provide efficiency measurements.

The release dates also matter for platform planning. The AMD GPU launched on January 3, 2023, while the Intel GPU has a release date of January 26, 2026. The Intel part is a newer design by roughly three years, which could mean better driver maturity for newer APIs and features, though both support DirectX 12 Ultimate and Vulkan 1.4.

Both GPUs sit at the 50th percentile against all GPUs in the database, indicating they are mid-range parts overall. Neither has a launch MSRP recorded, so no pricing analysis is possible from the data.
