AMD Radeon PRO W7800 vs Intel Arc G3 Extreme Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive performance separation between the AMD Radeon PRO W7800 and the Intel Arc G3 Extreme. The AMD Radeon PRO W7800 delivers an average benchmark score of 164,894 across its two recorded tests, placing it in the 97th percentile of all GPUs in the database. The Intel Arc G3 Extreme, by contrast, currently has no recorded benchmark scores, an average score of 0, and sits in the 50th percentile. This places the two products at opposite ends of the performance spectrum.

In the Geekbench OpenCL test, the AMD Radeon PRO W7800 scores 154,366 points. The Intel Arc G3 Extreme has no recorded result for this workload. The Geekbench Vulkan test shows the AMD part scoring 175,422 points, again with no corresponding Intel result. The absence of any benchmark data for the Intel Arc G3 Extreme means the database cannot compute a head-to-head win count for either product; both entries show zero wins in direct comparisons.

The AMD Radeon PRO W7800's average score of 164,894 places it within a tight competitive cluster. It trails the NVIDIA RTX 4500 Ada Generation by 0.7 percent (that card averages 166,094), sits 0.2 percent behind the NVIDIA RTX A5500 (165,217), and runs 1.5 percent ahead of the NVIDIA A100 PCIe 40 GB (162,504). The AMD Radeon Pro W6900X leads it by 2.2 percent with a score of 168,574. These margins are small, indicating that the Radeon PRO W7800 is firmly positioned among established workstation and data-center class accelerators.

The Intel Arc G3 Extreme's 50th percentile ranking and lack of scores mean it cannot be placed relative to any rivals in the database. Its performance class is effectively undefined until measurements are recorded. The only concrete signal from the data is that its theoretical specifications are far below the AMD part, which aligns with its position as an integrated graphics processor rather than a discrete workstation card.

The Verdict

The data supports a clear distinction: the AMD Radeon PRO W7800 is a high-end discrete workstation GPU with validated benchmark results, while the Intel Arc G3 Extreme is an integrated graphics processor with no recorded performance data. For any workload that relies on measured compute results, the Radeon PRO W7800 is the only option with evidence of capability. Its 97th percentile ranking and an average score of 164,894 place it in the upper tier of all GPUs tracked by the database.

The Intel Arc G3 Extreme, with its 50th percentile placement and zero average score, cannot be recommended for any task where performance numbers matter. The database shows no results for OpenCL or Vulkan, and its nearest rivals list is empty. This is not a close contest; it is a comparison between a measured product and one that has yet to produce any data.

From the specification perspective, the AMD part is designed for demanding professional workloads. It carries 32 GB of dedicated GDDR6 memory, a 256-bit bus, and 576.0 GB/s of bandwidth. The Intel part uses system shared memory, making its bandwidth system dependent. The AMD card also offers 4,480 shading units, 280 TMUs, and 128 ROPs, compared to 1,536 shading units, 48 TMUs, and 24 ROPs on the Intel part. These are not minor gaps; the AMD GPU has roughly three times the shading units and five times the ROPs.

The only scenario where the Intel Arc G3 Extreme makes sense from the data is one where a discrete GPU is not an option. It is an integrated processor (IGP) with a 80 W TDP, no power connectors, and portable device dependent display outputs. The AMD Radeon PRO W7800 requires a 600 W suggested power supply, dual-slot spacing, and two 8-pin connectors. For a compact, low-power integrated solution, the Intel part fits that profile, but it cannot compete on measured performance.

Specification Differences

The two GPUs differ across nearly every measurable specification. The AMD Radeon PRO W7800 uses the Navi 31 chip built on TSMC's 5 nm process, with 57,700 million transistors on a 529 mm² die. The Intel Arc G3 Extreme uses the Panther Lake chip on Intel's 3 nm process, with transistor count and die size listed as unknown. The AMD part has a transistor density of 109.1M per mm², a figure not applicable to the Intel part.

Clock speeds show a notable divergence. The Radeon PRO W7800 runs at a base clock of 1895 MHz and a boost clock of 2525 MHz, with memory at 2250 MHz (18 Gbps effective). The Arc G3 Extreme has a base clock of 300 MHz and a boost clock of 2500 MHz, with system shared memory that has no fixed clock. The AMD card's memory bandwidth is a fixed 576.0 GB/s, while the Intel part's bandwidth is system dependent.

Compute resources differ by a wide margin. The Radeon PRO W7800 has 4,480 shading units, 280 TMUs, 128 ROPs, and 70 ray tracing cores. The Arc G3 Extreme has 1,536 shading units, 48 TMUs, 24 ROPs, and 12 ray tracing cores. The AMD part also produces 323.2 GPixel/s and 707.0 GTexel/s, versus 60.00 GPixel/s and 120.0 GTexel/s for the Intel part. Floating point performance is 45.25 TFLOPS FP32 and 90.50 TFLOPS FP16 for AMD, compared to 7.680 TFLOPS FP32 and 15.36 TFLOPS FP16 for Intel.

Power and physical specifications diverge sharply. The AMD card has a 260 W TDP, dual-slot width, two 8-pin power connectors, and a 600 W suggested power supply. The Intel part has an 80 W TDP, is an IGP with no power connectors and no suggested PSU. The Radeon PRO W7800 measures 280 mm by 110 mm by 40 mm, while the Arc G3 Extreme has no listed dimensions. The AMD card uses a PCIe 4.0 x16 bus interface; the Intel part uses IGP. Display outputs also differ: the AMD card offers 3x DisplayPort 2.1 and 1x mini-DisplayPort 2.1, while the Intel card's outputs are portable device dependent.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The AMD Radeon PRO W7800 has a launch MSRP of 2,499 USD; the Intel Arc G3 Extreme has no launch MSRP listed.

Architecture Differences

The AMD Radeon PRO W7800 is built on the RDNA 3.0 architecture, with the codename Plum Bonito, and belongs to the Radeon Pro Navi generation (Navi III Series). The Intel Arc G3 Extreme uses the Xe3-LPG architecture, belongs to the Arc Graphics-M generation (Panther Lake), and has no codename listed in the database.

The manufacturing approach differs fundamentally. AMD uses TSMC as its foundry with a 5 nm process, while Intel uses its own foundry with a 3 nm process. The AMD chip integrates 57,700 million transistors, a figure that is unknown for the Intel part. The die size for AMD is 529 mm², while Intel's is unknown. This reflects the discrete versus integrated nature of the two designs.

Memory architecture is a core distinction. The Radeon PRO W7800 uses dedicated 32 GB GDDR6 memory with a 256-bit bus, providing fixed 576.0 GB/s bandwidth. The Arc G3 Extreme relies on system shared memory, meaning its memory size, type, bus width, and bandwidth are all system dependent. This makes the Intel part's memory performance variable based on the host system, while the AMD card has predictable, dedicated bandwidth.

Ray tracing hardware also differs. The AMD part includes 70 ray tracing cores, while the Intel part has 12. The compute pipeline scales accordingly, with the AMD card's FP32 throughput of 45.25 TFLOPS dwarfing the Intel part's 7.680 TFLOPS. The same ratio holds for FP16: 90.50 TFLOPS versus 15.36 TFLOPS. The AMD GPU's texture rate of 707.0 GTexel/s and pixel rate of 323.2 GPixel/s are both more than five times the Intel part's respective figures.

The release timeline shows a generational gap. The AMD Radeon PRO W7800 launched on 2023-04-12 and lists its predecessor as the Radeon Pro Vega. The Intel Arc G3 Extreme has a release date of 2026-05-31, with no predecessor listed. Both are currently marked as Active in production status, but the Intel part is an integrated solution tied to a mobile or portable platform, while the AMD card is a full-size discrete workstation accelerator. The architecture choices reflect those roles: RDNA 3.0 prioritizes raw throughput for professional rendering and compute, while Xe3-LPG targets power efficiency and integration within a system-on-chip design.
