AMD Radeon PRO W7700 vs Intel Arc G3 Extreme Comparison

AMD Radeon PRO W7700 vs Intel Arc G3 Extreme

Where Each One Wins

The AMD Radeon PRO W7700 and the Intel Arc G3 Extreme occupy entirely different segments of the graphics market, and the recorded data reflects that separation clearly. The Radeon PRO W7700 is a professional workstation card with a 95th percentile ranking among all GPUs, while the Arc G3 Extreme is an integrated graphics solution with a 50th percentile ranking. The benchmark database shows that the Radeon PRO W7700 holds every measurable performance advantage, with no head-to-head benchmark wins recorded for the Intel part.

The Radeon PRO W7700 delivers an average benchmark score of 118,976, placing it ahead of several established NVIDIA workstation parts. In Geekbench OpenCL, it scores 108,245, and in Geekbench Vulkan, it reaches 129,706. These figures place it in the top 5% of all GPUs tracked in the database, a position that reflects its intended role as a high-end compute and rendering solution. The Intel Arc G3 Extreme, by contrast, has no recorded benchmark scores, an average score of zero, and a 50th percentile placement that puts it squarely in the middle of the performance distribution.

The performance split is not subtle. The Radeon PRO W7700 produces 31.95 TFLOPS of FP32 compute, while the Intel part produces 7.680 TFLOPS, a difference of roughly 4.2 times. The pixel rate on the AMD card is 249.6 GPixel/s versus 60.00 GPixel/s on the Intel part, and the texture rate is 499.2 GTexel/s versus 120.0 GTexel/s. For any workload that depends on raw compute throughput, rasterization, or texture filtering, the Radeon PRO W7700 is the clear winner.

Where the Intel Arc G3 Extreme holds its ground is in power efficiency and physical footprint. The 80 W TDP and IGP (integrated graphics processor) form factor make it suitable for compact, portable systems where the Radeon PRO W7700's 190 W TDP and dual-slot, 241 mm length would be impractical. The Intel part also uses system shared memory, which means it draws no dedicated video memory allocation and relies on the host system's RAM. This design choice eliminates the need for a power connector, a separate memory bus, or any discrete cooling solution beyond what the processor package already provides.

The database indicates zero wins for either part in head-to-head comparisons, which is consistent with the absence of head-to-head benchmark entries. The practical interpretation is that these two products do not compete in the same market segment. The Radeon PRO W7700 is built for dedicated workstation duty, while the Arc G3 Extreme is an integrated solution for mobile or low-power systems.

Architecture Differences

The architectural gap between these two GPUs is substantial. The AMD Radeon PRO W7700 uses the Navi 32 chip built on TSMC's 5 nm process, with 28,100 million transistors on a 346 mm² die. This yields a transistor density of 81.2 million transistors per square millimeter. The Intel Arc G3 Extreme uses the Panther Lake chip built on Intel's 3 nm process, but the database lists its transistor count and die size as unknown, with no density figure available.

The Radeon PRO W7700 is based on RDNA 3.0 architecture, codenamed Wheat Nas, and belongs to the Radeon Pro Navi generation, specifically the Navi III Series. The Intel part uses Xe3-LPG architecture and belongs to the Arc Graphics-M generation for Panther Lake. Neither part uses a second-generation architecture; the AMD card is a dedicated discrete GPU, while the Intel part is an integrated graphics processor with no separate slot width, power connector, or bus interface beyond "IGP."

The compute resource allocation differs dramatically. The Radeon PRO W7700 packs 3,072 shading units, 192 texture mapping units, 96 render output units, and 48 ray tracing cores. The Intel Arc G3 Extreme has 1,536 shading units, 48 texture mapping units, 24 render output units, and 12 ray tracing cores. The AMD part has exactly twice the shading units, four times the texture mapping units, four times the render output units, and four times the ray tracing cores.

Memory architecture also diverges completely. The Radeon PRO W7700 carries 16 GB of GDDR6 memory on a 256-bit bus, delivering 576.0 GB/s of bandwidth. The memory clock is 2250 MHz with 18 Gbps effective data rate. The Intel part uses system shared memory for capacity, type, bus width, and bandwidth, with the bandwidth listed as "System Dependent." The Intel memory clock is also listed as "System Shared."

Clock behavior differs as well. The Radeon PRO W7700 runs at a 1900 MHz base clock and boosts to 2600 MHz. The Intel Arc G3 Extreme has a much lower 300 MHz base clock but boosts to 2500 MHz. The large gap between base and boost on the Intel part suggests a power-constrained design that relies on burst performance rather than sustained high clocks.

Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical. The Radeon PRO W7700 uses PCIe 4.0 x16 and has four DisplayPort 2.1 outputs. The Intel part's display outputs are listed as "Portable Device Dependent," which reflects its integrated nature.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two GPUs, and no wins are recorded for either part. The absence of direct comparison data is itself informative, as it reflects the significant market positioning gap between a discrete workstation GPU and an integrated mobile graphics solution.

The closest comparative data comes from the Radeon PRO W7700's nearest rivals in the database. Its average benchmark score of 118,976 places it 1.3% ahead of the NVIDIA GB10, which scores 117,393. It is 1.6% ahead of the NVIDIA RTX 4000 SFF Ada Generation, which scores 117,088. Against the NVIDIA Tesla V100 SXM2 16 GB, the margin is 4%, with the rival scoring 114,395. The Radeon PRO W7700 is also 4.4% ahead of the NVIDIA RTX A5500 Mobile, which scores 113,944.

These margins are modest but consistent, showing that the Radeon PRO W7700 sits at the upper edge of its performance class. A 1.3% lead over the GB10 and a 1.6% lead over the RTX 4000 SFF Ada Generation indicate near-parity with those parts, while the 4% and 4.4% leads over the Tesla V100 and RTX A5500 Mobile show a clearer separation from older or lower-tier products.

For the Intel Arc G3 Extreme, there are no rival comparisons and no benchmark scores to analyze. The 50th percentile ranking places it at the median of all GPUs in the database, but without recorded scores, the database cannot quantify its performance against specific competitors.

The lack of direct head-to-head data means the performance relationship between these two products must be assessed through their individual specifications and recorded scores. The Radeon PRO W7700's Geekbench OpenCL score of 108,245 and Geekbench Vulkan score of 129,706 exceed anything recorded for the Intel part, which has no entries. The compute, pixel, and texture rate figures all favor the AMD card by factors ranging from roughly 4.2 to 4.2 times.

The Intel Arc G3 Extreme's 2500 MHz boost clock is close to the Radeon PRO W7700's 2600 MHz boost, but the AMD card sustains a 1900 MHz base clock compared to Intel's 300 MHz base. This disparity suggests the Intel part cannot maintain high clocks under sustained load, reinforcing the power-constrained nature of an 80 W integrated solution.

The Radeon PRO W7700's 576.0 GB/s of dedicated memory bandwidth versus the Intel part's system-dependent bandwidth further separates the two in memory-intensive workloads. The AMD card's 16 GB GDDR6 frame buffer provides consistent, predictable performance, while the Intel part depends entirely on the host system's memory configuration.

In summary, the recorded data shows a clear performance hierarchy. The Radeon PRO W7700 dominates in every measured category, with benchmark scores, compute throughput, memory bandwidth, and render output rates all favoring the AMD card. The Intel Arc G3 Extreme offers an integrated, low-power alternative with no recorded performance data, making direct numerical comparison impossible beyond the specification sheet differences.
