AMD Radeon PRO W7900 vs Intel Arc Graphics 4 Xe Mobile Comparison

The AMD Radeon PRO W7900 and Intel Arc Graphics 4 Xe Mobile occupy opposite ends of the graphics hardware spectrum. The W7900 is a professional workstation accelerator with a dedicated 48 GB memory pool and a triple-slot cooler, while the Intel part is an integrated graphics processor (IGP) built for portable devices with system-shared memory. The recorded data shows a 94th percentile ranking for the AMD card against all GPUs, compared to the 50th percentile for the Intel IGP, a gap that reflects their entirely different design targets.

Head-to-Head Benchmarks

The head-to-head benchmark table in the database is empty, so no direct comparison scores exist between these two parts. However, the aggregate benchmark data provides a clear picture. The AMD Radeon PRO W7900 records an average benchmark score of 110725 across its two submitted tests. The Intel Arc Graphics 4 Xe Mobile has no benchmark submissions at all, resulting in an average score of zero. This absence of recorded data for the Intel part means any quantitative comparison relies solely on the AMD card’s submitted results and the rival comparisons available for it.

The AMD card’s nearest rivals in the database include the AMD Radeon Pro Vega II with an average score of 109617, placing the W7900 just 1 percent ahead. The NVIDIA RTX A5500 Mobile scores 113944, which is 2.8 percent higher than the W7900. The AMD Radeon Pro W6600X scores 107342, putting the W7900 3.2 percent ahead. The NVIDIA Tesla V100 SXM2 16 GB scores 114395, which is 3.2 percent higher than the W7900. These deltas show the W7900 sitting in a competitive band among professional and mobile workstation parts, neither dominating nor being dominated by its closest recorded competitors.

The AMD card’s Geekbench OpenCL score is 84379, and its Geekbench Vulkan score is 137070. The Vulkan result is substantially higher, indicating strong driver optimization for that API. The Intel IGP has no comparable scores, so there is no measured baseline for its OpenCL or Vulkan performance in this database.

Architecture Differences

The AMD Radeon PRO W7900 uses the Navi 31 chip built on RDNA 3.0 architecture, with the codename Plum Bonito. It belongs to the Radeon Pro Navi (Navi III Series) generation. The chip is fabricated on a 5 nm process at TSMC and contains 57,700 million transistors on a 529 mm² die, giving a transistor density of 109.1 million per square millimeter.

The Intel Arc Graphics 4 Xe Mobile uses the Panther Lake chip built on Xe3-LPG architecture, belonging to the Arc Graphics-M (Panther Lake) generation. It is fabricated on a 3 nm process at Intel. The transistor count and die size are listed as unknown, and no transistor density figure is recorded.

The architectural differences extend to compute resources. The AMD card has 6144 shading units, 384 texture mapping units, 192 render output units, and 96 ray tracing cores. The Intel IGP has 512 shading units, 32 texture mapping units, 16 render output units, and 4 ray tracing cores. The AMD card’s compute capacity is an order of magnitude larger across every unit type.

The FP32 throughput figures confirm the scale gap. The AMD card delivers 61.32 TFLOPS of FP32 performance, while the Intel IGP delivers 2.355 TFLOPS. The AMD card’s FP16 performance matches its FP32 at 61.32 TFLOPS with a 1:1 ratio. The Intel IGP provides 4.710 TFLOPS of FP16 with a 2:1 ratio, meaning it processes two FP16 operations per FP32 operation. This ratio difference indicates distinct design philosophies: the AMD card treats both precisions equally, while the Intel part dedicates more throughput to reduced precision.

Memory architecture differs completely. The AMD card uses 48 GB of GDDR6 on a 384 bit bus with 864.0 GB/s of bandwidth. Memory clocks run at 2250 MHz with 18 Gbps effective speed. The Intel IGP uses system shared memory with a system dependent bandwidth, no dedicated memory size, and no independent bus width. This means the Intel part competes with the CPU for memory bandwidth, while the AMD card has a dedicated pool.

The process node difference matters for efficiency. Intel’s 3 nm process is newer than AMD’s 5 nm process, and the Intel part’s 25 W TDP versus the AMD card’s 295 W TDP shows the power envelope gap. The Intel IGP needs no power connectors and is an IGP slot width, while the AMD card requires a triple-slot cooler and two 8-pin power connectors with a 600 W suggested power supply.

Where Each One Wins

The AMD Radeon PRO W7900 wins in every measured performance category available in the database. Its 61.32 TFLOPS FP32 throughput is roughly 26 times the Intel IGP’s 2.355 TFLOPS. Its texture rate of 958.1 GTexel/s compares to 73.60 GTexel/s for the Intel part, a factor of about 13. Its pixel rate of 479.0 GPixel/s compares to 36.80 GPixel/s, a factor of about 13 as well. The AMD card’s 48 GB dedicated GDDR6 memory with 864.0 GB/s bandwidth is not comparable to shared system memory with system dependent bandwidth.

The Intel Arc Graphics 4 Xe Mobile wins in power consumption and physical integration. A 25 W TDP fits within a laptop or portable device thermal budget, while the AMD card’s 295 W TDP requires a desktop workstation chassis with substantial cooling. The Intel part is an IGP with no power connectors, no slot width, and no separate dimensions, meaning it is soldered onto the processor package. The AMD card measures 280 mm in length, 110 mm in height, and 51 mm in width, requiring a full expansion slot.

The Intel part also wins on process node, using 3 nm versus AMD’s 5 nm. This newer node contributes to the Intel part’s lower power draw, though the database does not record efficiency metrics directly. The Intel IGP’s FP16 to FP32 ratio of 2:1 gives it a relative advantage in reduced precision workloads compared to its own FP32 performance, unlike the AMD card’s 1:1 ratio.

For ray tracing, the AMD card has 96 ray tracing cores versus the Intel part’s 4. In workloads that scale with ray tracing core count, the AMD card has a massive advantage, though the database does not include a dedicated ray tracing benchmark for either part.

The Verdict

The recorded data shows a complete performance hierarchy separation between these two parts. The AMD Radeon PRO W7900 is built for dedicated workstation rendering, compute, and ray tracing workloads where 48 GB of GDDR6 memory, 864.0 GB/s of bandwidth, and 61.32 TFLOPS of FP32 throughput are necessary. Its 94th percentile ranking against all GPUs and its competitive position among rivals like the NVIDIA RTX A5500 Mobile and Tesla V100 SXM2 16 GB confirm it belongs in the professional high-end category.

The Intel Arc Graphics 4 Xe Mobile is an integrated processor for portable devices. Its 25 W TDP, lack of dedicated memory, and absence of benchmark submissions place it in the entry-level integrated segment. The 3 nm process node and 2:1 FP16 ratio are modern design elements, but the compute resources are minimal compared to the AMD card.

Anyone selecting between these parts is choosing between a desktop workstation accelerator and a laptop IGP. The AMD card requires a triple-slot cooler, 2x 8-pin power connectors, a 600 W power supply, and a PCIe 4.0 x16 slot. The Intel part needs none of those, as it is built into the processor. The database shows no scenario where the Intel IGP approaches the AMD card’s measured performance, but the Intel part’s power envelope and physical integration make it suitable for portable systems. The AMD card’s launch MSRP is 3,999 USD, and its benchmark scores justify that positioning within the professional market. The Intel part has no recorded launch MSRP, consistent with its integrated nature. The choice depends entirely on whether the workload requires dedicated workstation performance or integrated mobile graphics.
