AMD Radeon PRO W7400 vs Intel Arc G3 Extreme Comparison

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark entries for the AMD Radeon PRO W7400 against the Intel Arc G3 Extreme. Both GPUs have an empty head-to-head benchmark array, and neither has a wins tally in direct comparisons. The average benchmark score for both entries is 0, and both sit at the 50th percentile among all GPUs in the database. Without direct measurement data, the performance relationship between these two parts must be established from their respective architectural specifications and computed throughput rates.

FP32 compute is nearly identical between the two. The AMD Radeon PRO W7400 delivers 7.885 TFLOPS, while the Intel Arc G3 Extreme delivers 7.680 TFLOPS. The AMD part holds a margin of 0.205 TFLOPS, approximately 2.7% higher. This is a narrow lead, and in real workloads the difference would be within run-to-run variance. Pixel throughput favors AMD at 70.40 GPixel/s versus 60.00 GPixel/s, a 10.40 GPixel/s gap, roughly 17.3% higher. Texture rate is closer: 123.2 GTexel/s for AMD versus 120.0 GTexel/s for Intel, a difference of 3.2 GTexel/s, about 2.7%.

The Intel part pulls ahead decisively in half-precision compute. The Arc G3 Extreme delivers 15.36 TFLOPS FP16, exactly double its FP32 rate, while the AMD Radeon PRO W7400 offers 7.885 TFLOPS FP16 at a 1:1 ratio with FP32. The Intel advantage here is 7.475 TFLOPS, meaning it processes FP16 at approximately 1.95 times the AMD rate. For workloads that can exploit packed FP16 or mixed-precision math, the Intel architecture provides substantially more throughput.

Clock behavior also separates the two. The Intel Arc G3 Extreme boosts to 2500 MHz, while the AMD Radeon PRO W7400 boosts to 1100 MHz with a base clock of 330 MHz. The Intel base clock is 300 MHz. Despite the lower clock, the AMD part achieves higher pixel and texture rates through a wider execution pipeline. The AMD GPU has 1792 shading units, 112 TMUs, and 64 ROPs, while the Intel GPU has 1536 shading units, 48 TMUs, and 24 ROPs. The AMD ROP count is 2.67 times higher, and the TMU count is 2.33 times higher.

Memory bandwidth heavily favors AMD. The Radeon PRO W7400 uses 8 GB of GDDR6 on a 128-bit bus, delivering 172.8 GB/s. The Intel Arc G3 Extreme uses system shared memory with bandwidth listed as system dependent. No fixed bandwidth figure exists for the Intel part, so direct comparison is not possible from the database. The AMD memory clock is 1350 MHz, translating to 10.8 Gbps effective. The Intel memory clock is simply listed as system shared.

Where Each One Wins

The AMD Radeon PRO W7400 wins in rasterization throughput. Its pixel rate of 70.40 GPixel/s and texture rate of 123.2 GTexel/s exceed the Intel figures of 60.00 GPixel/s and 120.0 GTexel/s. The ROP count of 64 versus 24 gives AMD a clear structural advantage in fill-rate-bound scenes, such as high-resolution rendering with heavy overdraw. The TMU count of 112 versus 48 supports more texture fetches per clock, benefiting detailed material workloads.

The AMD part also wins in memory capacity and dedicated bandwidth characteristics. It has 8 GB of dedicated GDDR6, while the Intel GPU shares system memory. For GPU-bound tasks where memory traffic is isolated from CPU traffic, the AMD design provides consistent bandwidth of 172.8 GB/s. The Intel part depends on the host platform's memory subsystem, so its bandwidth cannot be guaranteed and varies with system configuration.

The Intel Arc G3 Extreme wins in FP16 compute. Its 15.36 TFLOPS FP16 throughput is roughly double its FP32 rate, making it better suited for workloads that use half-precision arithmetic. Machine learning inference, certain image processing pipelines, and some compute shaders can use FP16 to double throughput. The AMD part provides 7.885 TFLOPS regardless of precision, so FP16 workloads gain nothing over FP32.

The Intel part also wins in clock speed. A boost of 2500 MHz is more than double the AMD boost of 1100 MHz. For latency-sensitive workloads that do not scale with parallel width, the higher clock can reduce per-thread execution time. The Intel design also has a lower base clock of 300 MHz versus 330 MHz, but the boost advantage is substantial.

Power consumption differs, with the AMD part rated at 55 W TDP and the Intel part at 80 W TDP. The AMD GPU delivers its rasterization advantages within a lower power envelope. The Intel GPU requires more power but offers higher clocks and double-rate FP16.

Architecture Differences

The AMD Radeon PRO W7400 uses the Navi 33 chip built on RDNA 3.0 architecture, with the codename Hotpink Bonefish. It belongs to the Radeon Pro Navi (Navi III Series) generation. The process node is 6 nm at TSMC. The die contains 13,300 million transistors on a 204 mm² area, giving a transistor density of 65.2 million per square millimeter. The manufacturing process is a mature node with a relatively large die for the transistor count.

The Intel Arc G3 Extreme uses the Panther Lake chip built on Xe3-LPG architecture. It belongs to the Arc Graphics-M (Panther Lake) generation. The process node is 3 nm at Intel's own foundry. Transistor count and die size are listed as unknown in the database, so no density figure is available. The 3 nm node is a more advanced manufacturing process than the AMD 6 nm node, which typically allows higher transistor density and lower power per transistor.

Ray tracing hardware differs. The AMD GPU has 28 ray tracing cores, while the Intel GPU has 12. The AMD count is more than double. However, ray tracing performance depends on architecture efficiency, not just core count. The database does not include ray tracing benchmark data for either part.

API support is identical. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Neither part has tensor cores listed. The AMD GPU has no tensor core field populated, and the Intel GPU also has a null tensor core value. Both are 12 Ultimate compliant, meaning they support hardware ray tracing, mesh shaders, variable rate shading, and other DX12 Ultimate features.

The AMD part is a discrete add-in board. It uses a PCIe 4.0 x8 bus interface, requires no power connectors, and fits in a single slot. Its dimensions are 168 mm length, 69 mm height, and 20 mm width. The Intel part is an integrated graphics processor with an IGP bus interface. It has no slot width, no dimensions listed, and no separate power connectors. It relies on the host system for power delivery.

Memory architecture is fundamentally different. The AMD GPU has dedicated GDDR6 memory with a fixed 128-bit bus and fixed bandwidth. The Intel GPU uses system shared memory, meaning it accesses the host's main memory through the system bus. This affects memory latency, bandwidth, and capacity, all of which are system dependent for the Intel part.
