AMD Radeon PRO W7800 vs Intel Arc G3 Comparison

AMD Radeon PRO W7800 vs Intel Arc G3

The Verdict

The database shows two products at opposite ends of the graphics spectrum. The AMD Radeon PRO W7800 is a professional workstation card from the Navi III Series, built on the RDNA 3.0 architecture with a 5 nm process from TSMC. It targets compute-heavy workloads with 32 GB of dedicated GDDR6 memory, a 256 bit bus, and a 260 W TDP that requires a 600 W power supply. The Intel Arc G3 is a mobile integrated graphics processor from the Panther Lake generation, using the Xe3-LPG architecture on Intel's own 3 nm process. It uses system shared memory, draws just 25 W, and carries no power connectors at all.

The measured data decisively favors the AMD card. The W7800 posts an average benchmark score of 164894, placing it in the 97th percentile among all GPUs in the database. The Arc G3 has no recorded benchmark scores and sits at the 50th percentile, meaning it represents the midpoint of the performance distribution. For users who need professional rendering, large memory buffers, or sustained compute throughput, the W7800 is the only meaningful choice from this data. The Arc G3 is a low-power integrated solution that appears in portable devices where the GPU must share system resources and physical space with the CPU.

Architecture Differences

The two products share no common silicon. The AMD Radeon PRO W7800 uses the Navi 31 chip, codenamed Plum Bonito, built on RDNA 3.0. It is manufactured on a 5 nm process at TSMC with 57,700 million transistors on a 529 mm² die, yielding a transistor density of 109.1M per mm². The Intel Arc G3 uses the Panther Lake chip with the Xe3-LPG architecture, fabricated on Intel's own 3 nm process. The database lists its transistor count and die size as unknown, and no density figure is available.

The execution resources differ sharply. The W7800 carries 4,480 shading units, 280 texture mapping units, 128 ROPs, and 70 ray tracing cores. The Arc G3 carries 1,280 shading units, 40 TMUs, 20 ROPs, and 10 ray tracing cores. That puts the AMD card at 3.5 times the shading units, 7 times the TMUs, and 7 times the ROPs of the Intel part. Neither product lists tensor cores.

Clock behavior also diverges. The W7800 runs a base clock of 1895 MHz with a boost of 2525 MHz, while the Arc G3 runs a low 300 MHz base and a 2400 MHz boost. The memory subsystems are fundamentally different. The W7800 uses 32 GB of GDDR6 with a 256 bit bus and 576.0 GB/s of bandwidth. The Arc G3 uses system shared memory with a system dependent bus width and bandwidth. The AMD card's memory clock is 2250 MHz with 18 Gbps effective transfer, while the Intel part has no dedicated memory clock.

Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The W7800 delivers 323.2 GPixel/s pixel rate, 707.0 GTexel/s texture rate, 45.25 TFLOPS FP32, and 90.50 TFLOPS FP16 (2:1). The Arc G3 delivers 48.00 GPixel/s, 96.00 GTexel/s, 6.144 TFLOPS FP32, and 12.29 TFLOPS FP16 (2:1). The AMD card is roughly 7.4 times faster in FP32 compute.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between these two products, and the win counters for both sides are zero. The comparison must therefore rely on the individually recorded benchmark results and the architectural throughput figures.

The W7800 has two recorded benchmark results. In Geekbench OpenCL it scores 154366, and in Geekbench Vulkan it scores 175422. These produce an average benchmark score of 164894. The Arc G3 has no recorded benchmarks in the database, leaving its average score at zero.

The W7800's average score of 164894 places it near several NVIDIA workstation and data center parts. The closest rival is the NVIDIA RTX A5500 with an average score of 165217, which is 0.2% higher than the W7800. The NVIDIA RTX 4500 Ada Generation scores 166094, which is 0.7% higher. The AMD Radeon Pro W6900X scores 168574, which is 2.2% higher. The only rival the W7800 beats in this group is the NVIDIA A100 PCIe 40 GB at 162504, which sits 1.5% lower. The W7800's 97th percentile ranking confirms that it sits among the top tier of all GPUs in the database.

The Arc G3's 50th percentile with no scores means it cannot be compared to any specific rival in the recorded data. Its position in the middle of the distribution reflects the lack of measured performance, not an established result.

Where Each One Wins

The AMD Radeon PRO W7800 wins in every measured or recorded category. Its average benchmark score of 164894 places it in the 97th percentile of all GPUs, with Geekbench OpenCL at 154366 and Geekbench Vulkan at 175422. The Arc G3 has no recorded scores. The W7800 also wins decisively on memory capacity, memory bandwidth, shading units, TMUs, ROPs, RT cores, pixel rate, texture rate, and both FP32 and FP16 compute throughput.

The Arc G3 wins on power efficiency and physical integration. Its 25 W TDP versus the W7800's 260 W TDP means it draws roughly one tenth the power. It is an IGP with no power connectors, no suggested PSU, and no recorded dimensions, which indicates it is designed to be soldered directly into a portable device rather than installed in a desktop chassis.

The use case split is clear from the data. For workstation rendering, large memory workloads, or any task that benefits from 32 GB of GDDR6 and 576.0 GB/s of bandwidth, the W7800 is the product that delivers measurable results. Its nearest rivals are all professional NVIDIA and AMD cards within roughly 2.2% of its average score, confirming it competes in the upper tier of workstation GPUs. For a thin-and-light portable device where the GPU must share system memory and fit within a 25 W thermal envelope, the Arc G3 is the only applicable option, but the database contains no performance measurements to validate its capability.

The W7800's 2,499 USD launch MSRP reflects its position as a full-size professional accelerator. The Arc G3 has no recorded launch price, consistent with its role as an integrated component inside a larger portable product. Buyers choosing between these two are not making a performance trade-off; they are choosing between a dedicated workstation card and an integrated mobile GPU, and the recorded data supports the workstation card in every performance category.
