AMD Radeon PRO W7700 vs Intel Arc G3 Comparison

Where Each One Wins

The AMD Radeon PRO W7700 and Intel Arc G3 occupy completely different segments of the graphics hardware landscape. The Radeon PRO W7700 is a discrete workstation card designed for sustained, high-throughput compute and professional rendering workloads. Its benchmark results place it in the 95th percentile of all GPUs in the database, with an average benchmark score of 118,976. The Intel Arc G3, by contrast, is an integrated graphics processor (IGP) built into the Panther Lake mobile platform, carrying a 50th percentile ranking and no recorded standalone benchmark scores.

The use-case split is stark. The Radeon PRO W7700 delivers recorded performance in Geekbench OpenCL and Vulkan tests, scoring 108,245 and 129,706 respectively. These are compute-oriented workloads that stress raw shading throughput, memory bandwidth, and geometry processing. The Arc G3 has no benchmark entries in the database, which means the data cannot confirm any performance wins for it in head-to-head testing. Its role is defined by its specifications: a 25 W TDP, integrated form factor, and system-shared memory, all pointing toward lightweight, power-constrained mobile use rather than dedicated compute tasks.

The Radeon PRO W7700 wins on every measurable front in the database. It holds 3,072 shading units against the Arc G3's 1,280, 192 texture mapping units against 40, and 96 render output units against 20. Its FP32 throughput of 31.95 TFLOPS dwarfs the Arc G3's 6.144 TFLOPS. Memory bandwidth tells a similar story: 576.0 GB/s of dedicated GDDR6 bandwidth versus system-dependent shared memory. The Arc G3's only clear advantage is power consumption, drawing 25 W compared to 190 W, and its integrated nature requires no power connectors or dedicated slot.

Architecture Differences

The two GPUs come from different fabs, different architectures, and different design philosophies. The Radeon PRO W7700 uses the Navi 32 chip built on RDNA 3.0 architecture, fabricated by TSMC on a 5 nm process. Its die measures 346 mm² and contains 28,100 million transistors, yielding a transistor density of 81.2 million per square millimeter. The chip carries the codename Wheat Nas and belongs to the Radeon Pro Navi (Navi III Series) generation.

The Intel Arc G3 uses the Panther Lake chip with Xe3-LPG architecture, fabricated by Intel on a 3 nm process. Its transistor count and die size are listed as unknown in the database, and no codename is recorded. The generation field identifies it as Arc Graphics-M (Panther Lake), indicating a mobile-focused integrated solution.

Architectural features diverge significantly. The Radeon PRO W7700 includes 48 ray tracing cores, while the Arc G3 has 10. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level feature parity exists despite the internal differences. The Radeon PRO W7700 offers 16 GB of dedicated GDDR6 memory on a 256-bit bus, while the Arc G3 relies entirely on system-shared memory with system-dependent bandwidth. The Radeon PRO W7700 connects via PCIe 4.0 x16, whereas the Arc G3 is an IGP with no bus interface. Display outputs also differ: the Radeon PRO W7700 provides 4x DisplayPort 2.1, while the Arc G3's outputs are described as portable device dependent.

Clock behavior reveals further divergence. The Radeon PRO W7700 has a base clock of 1900 MHz and a boost clock of 2600 MHz, with memory running at 2250 MHz (18 Gbps effective). The Arc G3 has a 300 MHz base clock and 2400 MHz boost, with system-shared memory. The Radeon PRO W7700 achieves a pixel rate of 249.6 GPixel/s and texture rate of 499.2 GTexel/s. The Arc G3 delivers 48.00 GPixel/s and 96.00 GTexel/s, roughly one-fifth the pixel throughput and one-fifth the texture throughput.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between these two GPUs, and the win counters show zero for both sides. This absence of recorded comparative data means the analysis must rely on the individually recorded benchmarks and the specification differences.

The Radeon PRO W7700's Geekbench OpenCL score of 108,245 and Vulkan score of 129,706 place it firmly in the upper tier of the database. Its average benchmark score of 118,976 puts it 1.3% ahead of the NVIDIA GB10, 1.6% ahead of the NVIDIA RTX 4000 SFF Ada Generation, 4% ahead of the NVIDIA Tesla V100 SXM2 16 GB, and 4.4% ahead of the NVIDIA RTX A5500 Mobile. These nearest rival deltas show that the Radeon PRO W7700 sits in competitive territory among professional and high-end workstation GPUs.

The Intel Arc G3, with an average benchmark score of 0 and no entries in its benchmark array, cannot be placed relative to any rivals in the database. Its percentile ranking of 50 places it at the median of all GPUs, but without recorded scores, this ranking likely reflects its specification-based classification rather than measured performance.

The compute gap between the two is quantifiable through specifications. The Radeon PRO W7700's FP32 throughput of 31.95 TFLOPS is roughly 5.2 times the Arc G3's 6.144 TFLOPS. The Radeon PRO W7700's 249.6 GPixel/s pixel rate is 5.2 times the Arc G3's 48.00 GPixel/s. The texture rate of 499.2 GTexel/s versus 96.00 GTexel/s shows the same approximate ratio. These consistent multipliers indicate that the Radeon PRO W7700 is designed for roughly five times the rasterization and compute workload of the Arc G3.

The Verdict

The recorded data supports only one conclusion for compute-heavy professional workloads: the AMD Radeon PRO W7700 is the significantly more capable GPU. Its 95th percentile ranking, average benchmark score of 118,976, and recorded Geekbench OpenCL and Vulkan scores demonstrate measurable performance that the Intel Arc G3 cannot match, as the Arc G3 has no recorded benchmarks at all. The Radeon PRO W7700's nearest rivals, including the NVIDIA GB10 and RTX 4000 SFF Ada Generation, sit within 1.3% to 1.6% of its average score, confirming its position among serious workstation hardware.

The Intel Arc G3 is a different kind of product entirely. As an integrated GPU with a 25 W TDP, no power connectors, and system-shared memory, it is built for power efficiency and portability, not compute throughput. Its 50th percentile ranking and absence of benchmark data mean the database cannot substantiate any performance claims for it. The 3 nm Intel process node and active production status suggest a modern, efficient design, but efficiency does not translate into workstation-class compute results.

For users requiring dedicated GPU compute, 16 GB of GDDR6 memory, and 576.0 GB/s of bandwidth, the Radeon PRO W7700 is the only option with recorded data supporting its capabilities. The Arc G3 suits a scenario where 25 W power draw and integrated form factor matter more than raw throughput, but the database offers no measured evidence of its performance in any workload. The choice, based strictly on the recorded facts, is clear: the Radeon PRO W7700 for compute, the Arc G3 for ultra-low-power integrated graphics.
