AMD Radeon PRO W7900 vs Intel Arc G3 Comparison

Head-to-Head Benchmarks

The recorded data for these two GPUs shows a stark contrast in benchmark availability. The AMD Radeon PRO W7900 has two completed benchmark runs in the database, while the Intel Arc G3 has no recorded benchmark scores at all. The database shows a single average benchmark score for the W7900 of 110,725, placing it in the 94th percentile of all GPUs. The Arc G3 sits at the 50th percentile with an average benchmark score of zero, indicating no measurable performance data has been collected.

The W7900 delivers 84,379 in Geekbench OpenCL and 137,070 in Geekbench Vulkan. The OpenCL score reflects compute workloads that rely on raw shading throughput, while the Vulkan score shows stronger behavior in graphics API workloads, a common pattern for RDNA architectures. The Arc G3 provides no comparable figures, so any head-to-head comparison must rely on architectural specifications rather than measured outcomes.

In the nearest rivals table, the W7900 sits within a narrow performance band. It trails the NVIDIA Tesla V100 SXM2 16 GB by 3.2 percent, whose average score is 114,395. It also trails the NVIDIA RTX A5500 Mobile by 2.8 percent, with that card averaging 113,944. Against AMD's own Radeon Pro W6600X, the W7900 leads by 3.2 percent, that card scoring 107,342. The closest competitor is the Radeon Pro Vega II, which scores 109,617, a delta of only 1 percent. These margins indicate that the W7900 sits in a competitive mid-to-high range where small percentage differences separate adjacent products.

The Arc G3 has no rivals listed, no wins, and no head-to-head benchmark entries. This absence of data means the database cannot substantiate any direct performance claims for the Intel part.

Architecture Differences

The two GPUs diverge fundamentally in their design targets. The AMD Radeon PRO W7900 uses the Navi 31 chip on the RDNA 3.0 architecture, with the Plum Bonito codename. It belongs to the Radeon Pro Navi generation, specifically the Navi III Series. The Intel Arc G3 uses the Panther Lake chip on the Xe3-LPG architecture and falls under the Arc Graphics-M generation. The W7900 is built on a 5 nm process at TSMC, while the Arc G3 uses a 3 nm process at Intel's own foundry. The W7900 integrates 57,700 million transistors across a 529 mm² die, yielding a transistor density of 109.1 million per square millimeter. The Arc G3 has unknown transistor counts and die size in the database, so no density figure exists.

Memory configuration separates these products completely. The W7900 carries 48 GB of GDDR6 on a 384-bit bus, producing 864.0 GB/s of bandwidth. Its memory clock runs at 2250 MHz, or 18 Gbps effective. The Arc G3 uses system shared memory, with type, bus width, and bandwidth all listed as system dependent. This indicates the Intel part relies on the host platform's memory subsystem rather than dedicated VRAM.

Compute resources show a large scale difference. The W7900 has 6,144 shading units, 384 texture mapping units, 192 raster operation units, and 96 ray tracing cores. The Arc G3 has 1,280 shading units, 40 TMUs, 20 ROPs, and 10 ray tracing cores. Pixel rates reflect this gap: the W7900 reaches 479.0 GPixel/s, while the Arc G3 manages 48.00 GPixel/s. Texture rates are 958.1 GTexel/s versus 96.00 GTexel/s. Floating point performance also diverges sharply. The W7900 delivers 61.32 TFLOPS in FP32 and the same 61.32 TFLOPS in FP16 at a 1:1 ratio. The Arc G3 produces 6.144 TFLOPS in FP32 and 12.29 TFLOPS in FP16 at a 2:1 ratio, meaning it trades FP32 throughput for doubled FP16 work.

Clock behavior differs as well. The W7900 has a 1760 MHz base clock and a 2495 MHz boost clock. The Arc G3 starts at 300 MHz base and boosts to 2400 MHz. The lower base clock for the Intel part suggests a power-constrained design that ramps up under load. Power consumption reflects this: the W7900 has a TDP of 295 W with two 8-pin power connectors and a suggested PSU of 600 W. The Arc G3 has a 25 W TDP, no power connectors, and no suggested PSU, indicating an integrated graphics processor designed for portable devices.

Physical and connectivity differences follow the same pattern. The W7900 is triple-slot, 280 mm long, 110 mm tall, and 51 mm wide, with three DisplayPort 2.1 outputs plus one mini-DisplayPort 2.1. It uses a PCIe 4.0 x16 bus interface. The Arc G3 is an IGP with no slot width, no dimensions, no power connectors, and display outputs described as portable device dependent. Its bus interface is also IGP, meaning it connects directly to the processor package. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical.

Release timing differs by about three years. The W7900 launched on 2023-05-25, while the Arc G3 is scheduled for 2026-05-31. The W7900 has a predecessor in the Radeon Pro Vega line, while the Arc G3 has no predecessor recorded. Both are currently marked as active production status.

The Verdict

The database shows two products with entirely different roles. The AMD Radeon PRO W7900 is a dedicated workstation GPU with substantial compute resources, dedicated memory, and measured benchmark scores. The Intel Arc G3 is a low-power integrated graphics solution with no benchmark data and a fraction of the shading units, memory bandwidth, and pixel throughput.

For workloads that demand maximum FP32 compute, large frame buffers, or high memory bandwidth, the W7900 is the only option with recorded evidence. Its 48 GB GDDR6 configuration and 864.0 GB/s bandwidth support large datasets, while its 61.32 TFLOPS FP32 rating indicates strong compute throughput. The Arc G3 cannot match these specifications; its system shared memory and 6.144 TFLOPS FP32 place it in a different performance class.

For power-sensitive applications in portable devices, the Arc G3 has a clear advantage. Its 25 W TDP and IGP form factor require no external power and no add-in card slot. The W7900 needs 295 W, a triple-slot cooler, and a 600 W PSU recommendation, making it unsuitable for compact or mobile systems.

The percentile ranking supports this split. The W7900 sits in the 94th percentile of all GPUs, while the Arc G3 sits in the 50th percentile. That difference indicates the W7900 outperforms the vast majority of recorded GPUs, while the Arc G3 lands exactly in the middle of the distribution. No head-to-head benchmark results exist, so the verdict rests on specifications and the W7900's measured scores.

Where Each One Wins

The AMD Radeon PRO W7900 wins in every category where the database has measurable data. Its average benchmark score of 110,725 places it 1 percent ahead of the Radeon Pro Vega II, 3.2 percent ahead of the Radeon Pro W6600X, and within 3 percent of the NVIDIA RTX A5500 Mobile and Tesla V100 SXM2 16 GB. Those margins confirm the W7900 competes at a high level despite not leading its immediate rivals. The 94th percentile ranking reinforces this position.

The W7900's architectural advantages map directly to professional workloads. Its 6,144 shading units and 96 ray tracing cores provide ample parallelism for compute-heavy tasks. The 48 GB memory capacity supports large models and datasets that would exceed smaller frame buffers. The 864.0 GB/s bandwidth moves data quickly enough to feed those shading units. The triple-slot cooler and 295 W TDP indicate sustained operation under load, not burst performance.

The Intel Arc G3 wins on integration and power efficiency. Its 25 W TDP is a fraction of the W7900's 295 W, and its IGP form factor eliminates the need for a discrete card, power connectors, or extra cooling. The 3 nm process at Intel suggests a modern manufacturing node, though the database records no transistor count or die size to confirm density. The 2:1 FP16 ratio, delivering 12.29 TFLOPS, indicates the Arc G3 can double its throughput on half-precision workloads, which could benefit certain AI or media tasks. The 2400 MHz boost clock is close to the W7900's 2495 MHz, showing the Intel part can reach competitive clock speeds despite its low base clock.

The Arc G3 also wins on release timing. Scheduled for 2026-05-31, it is newer than the W7900's 2023-05-25 launch. Newer architecture and process node do not guarantee higher performance, as the specifications show, but they suggest the Intel part benefits from more recent design techniques.

In practical terms, the W7900 wins for dedicated workstations, rendering farms, or any environment where compute throughput and memory capacity take priority over power draw. The Arc G3 wins for thin-and-light laptops, low-power embedded systems, or any device where a discrete GPU is impractical. The database provides no evidence that the Arc G3 can approach the W7900 in raw performance, so the choice depends entirely on the target platform and workload requirements.
