AMD Radeon PRO W7900D vs Intel Arc G3 Extreme Comparison

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark results for the AMD Radeon PRO W7900D versus the Intel Arc G3 Extreme. Both products have empty benchmark arrays in the database, and the win counts are zero for each. The average benchmark score for both is 0, and each sits at the 50th percentile against all GPUs. Without measured frames per second, render times, or synthetic scores, the numerical comparison must rely entirely on the architectural and specification data provided.

What the data does allow is a computed comparison of raw throughput limits. The AMD Radeon PRO W7900D delivers 52.99 TFLOPS of FP32 compute, while the Intel Arc G3 Extreme delivers 7.680 TFLOPS. That places the AMD part at roughly 6.9 times the FP32 throughput of the Intel part. In FP16, the AMD card offers 52.99 TFLOPS at a 1:1 ratio, while the Intel part offers 15.36 TFLOPS at a 2:1 ratio. The AMD card leads by a factor of approximately 3.45 in FP16. Pixel throughput favors the AMD card at 414.0 GPixel/s versus 60.00 GPixel/s, a 6.9x advantage. Texture rate follows the same pattern: 827.9 GTexel/s versus 120.0 GTexel/s, again a 6.9x gap. These are theoretical peak rates, not application results, but they define the performance envelope for both devices.

Architecture Differences

The AMD Radeon PRO W7900D uses the Navi 31 chip built on RDNA 3.0 architecture, with the codename Plum Bonito. It belongs to the Radeon Pro Navi generation, specifically the Navi III Series. The process node is 5 nm at TSMC. The chip contains 57,700 million transistors on a 529 mm² die, yielding a transistor density of 109.1M per mm². The Intel Arc G3 Extreme uses the Panther Lake chip built on Xe3-LPG architecture and belongs to the Arc Graphics-M (Panther Lake) generation. It is fabricated on a 3 nm process at Intel. Transistor count and die size are listed as unknown in the database, so no density figure can be derived.

The AMD card is a discrete, triple-slot add-in board with 2x 8-pin power connectors and a suggested power supply of 600 W. Its thermal design power is 295 W. The Intel part is an integrated graphics processor, or IGP, with no power connectors and an 80 W TDP. The bus interface for the AMD card is PCIe 4.0 x16, while the Intel part uses an IGP bus interface. The AMD card measures 280 mm in length, 110 mm in height, and 51 mm in width. The Intel part has no recorded dimensions because it is integrated into a mobile or portable platform.

Memory architecture differs fundamentally. The AMD Radeon PRO W7900D has 48 GB of GDDR6 on a 384-bit bus, with a memory clock of 2250 MHz or 18 Gbps effective, producing 864.0 GB/s of bandwidth. The Intel Arc G3 Extreme uses system shared memory, with the type, bus width, and bandwidth all listed as system dependent. This means the Intel part's memory performance is tied to the host platform's system memory configuration, not a dedicated VRAM subsystem.

Clock behavior also diverges. The AMD card has a base clock of 1327 MHz and a boost clock of 2156 MHz. The Intel part has a base clock of 300 MHz and a boost clock of 2500 MHz. The Intel part boosts higher, but the AMD part sustains a much higher base clock. The AMD card operates with 6144 shading units, 384 texture mapping units, 192 render output units, and 96 ray tracing cores. The Intel part has 1536 shading units, 48 TMUs, 24 ROPs, and 12 ray tracing cores. Neither product lists tensor cores in the database.

API support is identical on paper: both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs differ. The AMD card has 3x DisplayPort 2.1 and 1x mini-DisplayPort 2.1. The Intel part's display outputs are listed as portable device dependent, reflecting its integrated nature. The AMD card's release date is 2025-09-24, and its predecessor is listed as Radeon Pro Vega. The Intel part's release date is 2026-05-31, with no predecessor recorded. Both are marked as active in production.

The FP16 ratio is a key architectural distinction. The AMD card executes FP16 at 1:1 with FP32, meaning the same 52.99 TFLOPS rate for both. The Intel card executes FP16 at 2:1, giving 15.36 TFLOPS of FP16 against 7.680 TFLOPS of FP32. This indicates the Intel architecture uses a packed FP16 path, while the AMD architecture does not double-rate FP16 on this part.

The Verdict

The data separates these two products by every measurable hardware category. The AMD Radeon PRO W7900D is a discrete workstation GPU with dedicated 48 GB GDDR6 memory, 864.0 GB/s of bandwidth, 52.99 TFLOPS FP32, and a 295 W TDP. The Intel Arc G3 Extreme is an integrated GPU on a 3 nm process with system shared memory, 7.680 TFLOPS FP32, and an 80 W TDP. Any workload that demands sustained compute throughput, high memory bandwidth, or large on-card memory capacity points to the AMD part. The Intel part is defined by its integration and low power draw, not by raw performance.

The database lists no launch MSRP for either product, so no cost comparison is possible from the recorded data. The AMD card launched on 2025-09-24, the Intel part is dated 2026-05-31. Both sit at the 50th percentile versus all GPUs, but that percentile is computed from an average benchmark score of 0 for each, so it carries no comparative weight.

Where Each One Wins

The AMD Radeon PRO W7900D wins in every raw compute category recorded. FP32 throughput is 52.99 TFLOPS against 7.680 TFLOPS. FP16 throughput is 52.99 TFLOPS against 15.36 TFLOPS. Pixel rate is 414.0 GPixel/s against 60.00 GPixel/s. Texture rate is 827.9 GTexel/s against 120.0 GTexel/s. The AMD card has 6144 shading units, 384 TMUs, 192 ROPs, and 96 ray tracing cores, all substantially higher than the Intel part's 1536 shading units, 48 TMUs, 24 ROPs, and 12 ray tracing cores. Memory bandwidth is 864.0 GB/s from dedicated GDDR6, versus system shared memory with no fixed bandwidth figure. The AMD card also has a higher base clock of 1327 MHz compared to 300 MHz, and it is a discrete PCIe 4.0 x16 card with dedicated display outputs, 3x DisplayPort 2.1 and 1x mini-DisplayPort 2.1. Workloads that stress sustained compute, large datasets that exceed 48 GB, or high-bandwidth rendering favor the AMD part.

The Intel Arc G3 Extreme wins in power efficiency and integration. Its TDP is 80 W versus 295 W, and it requires no power connectors or suggested power supply rating. It is an IGP, so it occupies no expansion slot and has no board dimensions to accommodate. Its process node is smaller at 3 nm versus 5 nm, and its boost clock is higher at 2500 MHz versus 2156 MHz. The Intel part also achieves its FP16 throughput at a 2:1 ratio, meaning it gets double the FP16 rate relative to its FP32 rate, a feature the AMD card does not provide on this part. For portable devices where the display output is device dependent and system memory is shared, the Intel part fits a low-power integrated design. The AMD card is a triple-slot board measuring 280 mm by 110 mm by 51 mm, which requires a case with substantial clearance. The Intel part has no such physical footprint.

The Intel part also carries a later release date of 2026-05-31, while the AMD card was released on 2025-09-24. Both products are active in production. The AMD card's predecessor is Radeon Pro Vega; the Intel part has no predecessor listed. The database records no direct benchmark wins for either product, so the win split is entirely derived from the specification deltas. The AMD Radeon PRO W7900D is the choice for compute and memory bound tasks. The Intel Arc G3 Extreme is the choice for integrated, low power platforms.
