AMD Radeon RX 6550S vs Intel Arc Graphics 2 Xe Mobile Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark entries for the AMD Radeon RX 6550S versus the Intel Arc Graphics 2 Xe Mobile. Both entries have zero benchmark scores, zero wins each, and no nearest rival data. Consequently, the analysis below relies entirely on the architectural and specification fields captured in the database.

The only quantitative comparison available comes from the peak FP32 and texture rates. AMD’s part delivers 4.915 TFLOPS of FP32 compute against Intel’s 1,280.0 GFLOPS, a factor of roughly 3.84x in favor of AMD. In texture throughput, AMD reaches 153.6 GTexel/s while Intel manages 40.00 GTexel/s, again a 3.84x gap. Pixel fill rates narrow only slightly: AMD produces 76.80 GPixel/s versus Intel’s 20.00 GPixel/s, a 3.84x difference again, consistent across all three rate metrics.

Clock behavior also differs sharply. AMD’s base clock sits at 2000 MHz with a boost of 2400 MHz and a game clock of 2170 MHz. Intel starts at a very low 300 MHz base but boosts to 2500 MHz. That 2200 MHz delta between base and boost on the Intel side suggests a power-constrained design that ramps aggressively under load, while AMD runs a much narrower 400 MHz span from base to boost.

Memory bandwidth is another decisive separator. AMD uses 4 GB of GDDR6 on a 64-bit bus, yielding 128.0 GB/s. Intel’s memory is system shared, with bandwidth marked as system dependent. No fixed bandwidth number exists for the Intel part, so the comparison remains qualitative: dedicated VRAM versus shared system memory.

Architecture Differences

The two GPUs come from different foundries and process nodes. AMD builds the Navi 24 chip on TSMC’s 6 nm process, with 5,400 million transistors packed into a 107 mm² die. That yields a transistor density of 50.5M per mm². Intel’s Wildcat Lake chip uses Intel’s 3 nm process, but the database lists transistor count and die size as unknown, so no density figure can be computed.

Architecturally, AMD uses RDNA 2.0, while Intel uses Xe3-LPG. AMD’s generation is listed as Navi Mobile (RX 6000M), and Intel’s as Arc Graphics-M (Wildcat Lake). The execution resources diverge substantially. AMD has 1024 shading units, 64 texture mapping units, and 32 ROPs. Intel has 256 shading units, 16 TMUs, and 8 ROPs. AMD also carries 16 ray tracing cores against Intel’s 2.

FP16 compute tells a similar story. AMD reaches 9.830 TFLOPS using a 2:1 ratio, while Intel reaches 2.560 TFLOPS with the same 2:1 ratio. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API feature parity exists on paper. The bus interface differs: AMD uses PCIe 4.0 x4, while Intel is listed as IGP, meaning it connects through the integrated graphics path rather than a dedicated PCIe link.

Power envelopes are far apart. AMD’s TDP is 50 W, and Intel’s is 25 W. Both are IGP-class slot widths with no power connectors. Display outputs for both are portable device dependent, indicating they target laptops or embedded mobile systems rather than desktop cards.

FAQ

Q: Which GPU has higher peak FP32 performance?

A: The AMD Radeon RX 6550S delivers 4.915 TFLOPS, compared to 1,280.0 GFLOPS for the Intel Arc Graphics 2 Xe Mobile, making AMD approximately 3.84x faster in this metric.

Q: How do the memory subsystems differ?

A: AMD uses 4 GB of GDDR6 on a 64-bit bus with 128.0 GB/s bandwidth. Intel uses system shared memory with a system dependent bandwidth, so no fixed capacity or bandwidth figure is recorded.

Q: Are the API feature sets identical?

A: Yes, both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4 according to the database.

Q: What process nodes do the two chips use?

A: AMD’s Navi 24 is fabricated on TSMC’s 6 nm process. Intel’s Wildcat Lake is fabricated on Intel’s 3 nm process. Intel’s transistor count and die size are unknown.

Q: How large is the difference in shading units?

A: AMD has 1024 shading units, while Intel has 256, a 4x difference in favor of AMD.

Q: Which GPU has a higher boost clock?

A: Intel’s boost clock is 2500 MHz, slightly higher than AMD’s 2400 MHz boost. However, Intel’s base clock is only 300 MHz versus AMD’s 2000 MHz.

The Verdict

Based strictly on the recorded data, the AMD Radeon RX 6550S dominates the Intel Arc Graphics 2 Xe Mobile in nearly every quantitative metric. AMD has 4x the shading units, 4x the TMUs, 4x the ROPs, 8x the ray tracing cores, and roughly 3.84x the FP32 throughput, texture rate, and pixel rate. AMD also provides dedicated 4 GB GDDR6 memory with 128.0 GB/s bandwidth, whereas Intel relies on system shared memory.

The Intel part does have advantages in two specific areas. It uses a more advanced 3 nm process node from Intel, and it has a higher boost clock at 2500 MHz. Additionally, Intel’s 25 W TDP is half of AMD’s 50 W, which may matter for thermal and battery considerations in thin mobile devices.

However, the performance gap is so large that the Intel part cannot be considered a direct competitor in raw rendering capability. The database shows no benchmark scores, so real-world application performance remains unmeasured, but the architectural deltas strongly favor AMD for any compute or graphics workload that scales with shading units and memory bandwidth.

Where Each One Wins

AMD wins decisively in every compute and graphics throughput category. The 4x shading unit advantage, 4x texture unit advantage, and 4x ROP advantage directly translate into higher fill rates and texture rates. The 3.84x FP32 lead means AMD handles more complex shaders and compute workloads per clock. The dedicated 128.0 GB/s GDDR6 bandwidth avoids the latency and contention issues of shared system memory, which is critical for texture-heavy games and high-resolution rendering. AMD also has 16 ray tracing cores versus Intel’s 2, giving it a substantial edge in ray-traced scenes.

Intel’s wins are limited to power efficiency and clock headroom. At 25 W TDP, the Intel part consumes half the power of AMD’s 50 W design. This could translate into longer battery life or quieter operation in thermally constrained chassis. The 2500 MHz boost clock edges out AMD’s 2400 MHz, suggesting Intel can spike higher in short bursts, though its 300 MHz base clock indicates it spends most of its time at low power states. The 3 nm Intel process node also represents a more advanced manufacturing technology, which may yield better idle efficiency despite the lower transistor count.

For use cases involving sustained 3D rendering, GPU compute, or gaming at meaningful settings, the AMD Radeon RX 6550S is the clear choice based on the recorded specifications. For ultra-portable devices prioritizing low power draw and minimal heat output, the Intel Arc Graphics 2 Xe Mobile may fit a narrower niche, provided the workload does not demand high throughput. The database shows no benchmark scores to validate real-world performance, so these conclusions rest entirely on the architectural and rate-based fields above.
