AMD Radeon PRO W7900D vs Intel Arc Graphics 2 Xe Mobile Comparison

Where Each One Wins

The recorded data shows two GPUs with completely different roles. The AMD Radeon PRO W7900D is a discrete workstation accelerator aimed at professional rendering, compute, and multi-display workloads. The Intel Arc Graphics 2 Xe Mobile is an integrated graphics solution built into a processor, designed for portable devices where power draw and physical space are constrained.

In raw compute throughput, the AMD part dominates decisively. It delivers 52.99 TFLOPS of FP32 compute, while the Intel integrated solution produces 1,280.0 GFLOPS (1.28 TFLOPS). That is a roughly 41x advantage in single-precision floating point performance. For FP16, the AMD card provides 52.99 TFLOPS with a 1:1 ratio, while the Intel part offers 2.560 TFLOPS with a 2:1 ratio. The AMD card wins every shading, texturing, and rasterization metric in the database.

The Intel part wins in efficiency and integration. Its TDP is 25 W, versus 295 W for the AMD card. It requires no power connectors and no separate slot. It is an IGP with system-shared memory, meaning it draws from the host system's memory pool rather than dedicated VRAM. The AMD card needs 2x 8-pin power connectors and a 600 W suggested PSU. For thin-and-light portables, the Intel solution is the only viable option of the two.

The AMD card also wins in memory capacity and bandwidth. It has 48 GB of GDDR6 on a 384-bit bus, delivering 864.0 GB/s of bandwidth. The Intel part uses system-shared memory with bandwidth that is system dependent, so no fixed figure exists. For large datasets, 3D scenes, or AI inference workloads that exceed integrated memory limits, the AMD card is the clear choice.

The Intel part wins on process node. It uses a 3 nm process from Intel, while the AMD card uses a 5 nm process from TSMC. The AMD card has 57,700 million transistors on a 529 mm² die, giving a transistor density of 109.1M per mm². The Intel part's transistor count and die size are listed as unknown in the database.

Neither GPU has recorded benchmark scores in the database. Both sit at the 50th percentile versus all GPUs, with an average benchmark score of 0. There are no head-to-head benchmark entries, and neither has nearest rivals listed. The analysis below therefore relies on architectural specifications and computed rates rather than application tests.

Architecture Differences

The AMD Radeon PRO W7900D uses the Navi 31 chip with RDNA 3.0 architecture, codenamed Plum Bonito. It belongs to the Radeon Pro Navi generation (Navi III Series). The Intel Arc Graphics 2 Xe Mobile uses the Wildcat Lake chip with Xe3-LPG architecture, belonging to the Arc Graphics-M generation (Wildcat Lake).

The process nodes differ. AMD uses a 5 nm process from TSMC. Intel uses a 3 nm process from its own foundry. The AMD chip integrates 57,700 million transistors on a 529 mm² die. Intel's transistor count and die size are not recorded in the database.

The core configurations are vastly different. The AMD card has 6,144 shading units, 384 texture mapping units, 192 ROPs, and 96 ray tracing cores. The Intel part has 256 shading units, 16 TMUs, 8 ROPs, and 2 ray tracing cores. The AMD card has 24 times the shading units, 24 times the TMUs, and 24 times the ROPs. It has 48 times the ray tracing cores.

Clock behavior differs significantly. The AMD card runs at a 1327 MHz base clock and 2156 MHz boost clock. The Intel part has a 300 MHz base clock and 2500 MHz boost clock. The Intel part boosts higher, but with far fewer execution units. The AMD card's memory clock is 2250 MHz with 18 Gbps effective data rate. The Intel part uses system-shared memory, so no dedicated memory clock exists.

Memory architecture separates these two completely. The AMD card has 48 GB of GDDR6 on a 384-bit bus. The Intel part has no dedicated VRAM; it shares system memory, with the bus width and bandwidth listed as system dependent. This is the fundamental architectural difference: one is a discrete GPU with its own memory pool, the other is an integrated GPU borrowing from the host.

The AMD card uses a PCIe 4.0 x16 bus interface. The Intel part is an IGP with no bus interface beyond the processor's internal fabric. Power delivery reflects this: the AMD card is triple-slot with 2x 8-pin connectors and a 600 W suggested PSU, while the Intel part is an IGP with no power connectors.

Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Neither has tensor cores listed in the database. The AMD card has 3x DisplayPort 2.1 plus 1x mini-DisplayPort 2.1. The Intel part's display outputs are portable device dependent.

The AMD card is 280 mm long, 110 mm high, and 51 mm wide. The Intel part has no recorded dimensions because it is integrated into a processor package. The AMD card was released on 2025-09-24, while the Intel part follows on 2026-04-15. Both are listed as active production parts. The AMD card's predecessor is Radeon Pro Vega, and the Intel part's predecessor is HD Graphics-M. Neither has a recorded successor.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between these two GPUs. The wins count is 0 for both sides, and the head-to-head benchmark array is empty. Neither GPU has an average benchmark score recorded; both show 0. Their percentile versus all GPUs is identical at 50. There are no nearest rivals listed for either part.

Without application-level test data, the comparison must rely on the computed rates and fixed specifications. The AMD card's pixel rate is 414.0 GPixel/s, which is 20.7 times the Intel part's 20.00 GPixel/s. The texture rate difference is even starker: 827.9 GTexel/s versus 40.00 GTexel/s, a factor of roughly 20.7. FP32 throughput shows a factor of approximately 41.4. FP16 throughput shows a factor of approximately 20.7 when comparing 52.99 TFLOPS to 2.560 TFLOPS.

Memory bandwidth is the largest gap. The AMD card sustains 864.0 GB/s from dedicated GDDR6. The Intel part's bandwidth is system dependent, meaning it varies with the host memory configuration. In any realistic portable system, shared memory bandwidth will be far lower than 864.0 GB/s, but the database does not record a fixed figure.

Clock speeds tell a different story. The Intel part boosts to 2500 MHz, which is 344 MHz higher than the AMD card's 2156 MHz boost. The Intel part also has a much lower base clock at 300 MHz versus 1327 MHz. Higher boost clocks on the Intel part do not compensate for the 24x difference in shading units, TMUs, and ROPs.

Ray tracing hardware follows the same pattern. The AMD card has 96 ray tracing cores, the Intel part has 2. That is a 48x difference. Both support DirectX 12 Ultimate with ray tracing feature levels, but the execution resources are not comparable.

The process node favors Intel. A 3 nm process versus 5 nm is a meaningful architectural advantage in density and power efficiency per transistor. The AMD card compensates with a massive die: 529 mm² containing 57,700 million transistors. Intel's die size and transistor count are unknown, so no density comparison is possible.

Power consumption is the clearest differentiator in the opposite direction. The AMD card draws 295 W and requires a 600 W suggested PSU. The Intel part fits within a 25 W TDP and needs no external power. For a desktop workstation with a triple-slot card measuring 280 mm in length, the AMD card is appropriate. For a portable device, the Intel IGP is the only option.

The Verdict

The data supports a clear split by use case. The AMD Radeon PRO W7900D is a workstation-class discrete GPU for systems that can accommodate a 295 W, triple-slot card with 2x 8-pin power connectors and a 600 W suggested PSU. It provides 48 GB of dedicated GDDR6 memory, 864.0 GB/s of bandwidth, and 52.99 TFLOPS of FP32 compute. Its 96 ray tracing cores and 6,144 shading units make it suited for professional rendering, large-scale compute, and multi-display workstation setups. The release date of 2025-09-24 places it earlier in the database timeline.

The Intel Arc Graphics 2 Xe Mobile is an integrated GPU for portable devices. Its 25 W TDP, lack of power connectors, and IGP form factor mean it fits into processors for thin-and-light systems. It shares system memory, so capacity and bandwidth depend on the host. Its 2,500 MHz boost clock and 3 nm process are modern, but its 256 shading units and 2 ray tracing cores limit it to light graphics workloads. The release date of 2026-04-15 places it later in the database timeline.

Neither GPU has benchmark scores, percentile rankings beyond the neutral 50th percentile, or rival comparisons in the database. The specifications alone determine the verdict. A system builder with a workstation chassis and a power budget should select the AMD Radeon PRO W7900D. A portable device designer constrained by power and space should select the Intel Arc Graphics 2 Xe Mobile. The two do not compete in the same market segment, and the recorded data confirms that.
