AMD Radeon PRO W7900D vs Intel Arc Graphics 4 Xe Mobile Comparison

Where Each One Wins

The AMD Radeon PRO W7900D and the Intel Arc Graphics 4 Xe Mobile occupy entirely separate segments of the GPU market, and the recorded data reflects this divide clearly. The AMD part is a triple-slot, 295 W discrete workstation accelerator built around the Navi 31 chip with 48 GB of GDDR6 memory. The Intel part is a 25 W integrated graphics processor (IGP) designed for mobile Panther Lake systems. There are no shared benchmark wins between the two; they do not compete in the same performance class, and the database records zero head-to-head benchmark results for this pairing.

The AMD Radeon PRO W7900D wins in every metric that matters for raw compute throughput, memory bandwidth, and rendering capacity. Its shading units, texture mapping units, render output units, and ray tracing cores all outnumber the Intel part by a wide margin. The data shows 6144 shading units, 384 TMUs, 192 ROPs, and 96 RT cores for the AMD card, versus 512 shading units, 32 TMUs, 16 ROPs, and 4 RT cores for the Intel IGP. The AMD card also holds the advantage in pixel rate, texture rate, and FP32 throughput, making it the clear choice for workstation rendering, simulation, and compute workloads.

The Intel Arc Graphics 4 Xe Mobile wins in power efficiency and integration. Its 25 W TDP is a fraction of the AMD card's 295 W requirement, and it requires no power connectors, no auxiliary cooling beyond the laptop chassis, and no dedicated slot space. The Intel part uses system shared memory, which means it can scale with whatever memory the host system provides, though the bandwidth is system dependent. For thin-and-light mobile devices, the Intel IGP is the only viable option between the two, since the AMD card is a triple-slot, 280 mm long add-in board that cannot physically fit into such systems.

The production timeline also separates these parts. The AMD Radeon PRO W7900D has a release date of 2025-09-24, while the Intel Arc Graphics 4 Xe Mobile has a release date of 2026-01-26. Both are listed as Active in production status. The AMD card's predecessor is the Radeon Pro Vega, while the Intel part has no recorded predecessor. Neither has a recorded successor.

Head-to-Head Benchmarks

The database records no head-to-head benchmark results between these two GPUs. The winsA and winsB counters are both zero, and the headToHeadBenchmarks array is empty. This is expected given the fundamental differences in form factor, target platform, and performance envelope. A comparison of their recorded specifications, however, provides a clear picture of the performance gap.

The most decisive difference lies in FP32 throughput. The AMD Radeon PRO W7900D delivers 52.99 TFLOPS, which is 22.5 times the Intel Arc Graphics 4 Xe Mobile's 2.355 TFLOPS. This ratio is consistent across other compute metrics. The AMD card's texture rate is 827.9 GTexel/s versus 73.60 GTexel/s for the Intel part, a factor of roughly 11.2. The pixel rate shows a similar pattern: 414.0 GPixel/s for AMD versus 36.80 GPixel/s for Intel, a factor of about 11.25.

Memory bandwidth is another area of complete separation. The AMD card provides 864.0 GB/s from its 48 GB GDDR6 configuration on a 384 bit bus. The Intel part relies on System Shared memory, with bandwidth listed as System Dependent. This means the Intel IGP's memory performance is entirely contingent on the host system's memory configuration, which cannot match a dedicated 384 bit GDDR6 interface.

The clock speeds also differ significantly, though the comparison is nuanced. The AMD card has a base clock of 1327 MHz and a boost clock of 2156 MHz. The Intel part has a base clock of 300 MHz and a boost clock of 2300 MHz. While the Intel part has a higher boost clock, its lower base clock and far smaller execution resources mean its overall throughput remains far below the AMD card's.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level feature parity exists. However, the raw execution resources are so different that no realistic workload would show the Intel part competing with the AMD card on raw performance.

Specification Differences

The two GPUs differ in nearly every physical and performance specification. The AMD Radeon PRO W7900D uses the Navi 31 chip built on TSMC's 5 nm process, with a die size of 529 mm² and 57,700 million transistors. The Intel Arc Graphics 4 Xe Mobile uses the Panther Lake chip on Intel's 3 nm process, with transistor count and die size both listed as unknown.

Memory configurations are completely different. The AMD card has 48 GB of GDDR6 on a 384 bit bus with 864.0 GB/s bandwidth. The Intel part uses System Shared memory, with type, bus width, and bandwidth all listed as System Shared or System Dependent.

Compute resources show a 12:1 ratio in the AMD card's favor. The AMD part has 6144 shading units, 384 TMUs, 192 ROPs, and 96 RT cores. The Intel part has 512 shading units, 32 TMUs, 16 ROPs, and 4 RT cores.

Clock behavior differs in both base and boost values. The AMD card runs at 1327 MHz base and 2156 MHz boost. The Intel part runs at 300 MHz base and 2300 MHz boost. Memory clock for the AMD card is 2250 MHz with 18 Gbps effective speed, while the Intel part has no dedicated memory clock.

Power and physical characteristics are polar opposites. The AMD card has a 295 W TDP, is triple-slot, requires 2x 8-pin power connectors, and has a suggested PSU of 600 W. Its dimensions are 280 mm length, 110 mm height, and 51 mm width. The Intel part has a 25 W TDP, is an IGP, requires no power connectors, has no suggested PSU, and has no recorded dimensions.

The AMD card uses a PCIe 4.0 x16 bus interface and provides 3x DisplayPort 2.1 plus 1x mini-DisplayPort 2.1 outputs. The Intel part has an IGP bus interface and its display outputs are listed as Portable Device Dependent.

Release dates differ by roughly four months, with the AMD card releasing on 2025-09-24 and the Intel part on 2026-01-26.

Architecture Differences

The AMD Radeon PRO W7900D is built on the RDNA 3.0 architecture, with the codename Plum Bonito, and belongs to the Radeon Pro Navi generation (Navi III Series). The Intel Arc Graphics 4 Xe Mobile uses the Xe3-LPG architecture and belongs to the Arc Graphics-M generation (Panther Lake). These are fundamentally different GPU designs with different design goals.

The RDNA 3.0 architecture in the AMD card is a high-performance discrete GPU design. It uses a chiplet-based approach with the Navi 31 die, fabricated on TSMC's 5 nm process. The 57,700 million transistor count on a 529 mm² die gives a transistor density of 109.1M per mm². This architecture prioritizes raw throughput, with a 1:1 FP16 to FP32 ratio that allows full-rate FP16 compute. The 96 RT cores indicate a dedicated ray tracing pipeline designed for professional visualization workloads.

The Xe3-LPG architecture in the Intel part is a low-power graphics design integrated into the Panther Lake mobile processor. It is fabricated on Intel's 3 nm process, though the transistor count and die size are not recorded. The 2:1 FP16 to FP32 ratio indicates that FP16 runs at double the rate of FP32, a common design for integrated graphics that need to handle mixed media workloads efficiently. The 4 RT cores provide basic ray tracing capability, but the architecture is clearly optimized for power efficiency rather than peak compute.

The memory architecture differences are structural. The AMD card uses dedicated GDDR6 memory with a full 384 bit bus, which is standard for discrete workstation GPUs. The Intel part uses system shared memory, meaning it accesses the host system's main memory through the IGP's memory controller. This eliminates the need for dedicated VRAM but makes bandwidth dependent on the host system's memory subsystem.

The display output strategy also reflects their intended platforms. The AMD card provides standard workstation display outputs (3x DisplayPort 2.1 and 1x mini-DisplayPort 2.1), while the Intel part's outputs are Portable Device Dependent, meaning they are determined by the laptop or mobile device manufacturer.

Both architectures support the same API feature set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. This means software targeting these APIs can run on either GPU, though performance will vary dramatically based on the hardware resources available.
