Intel Arc G3 Extreme vs NVIDIA RTX PRO 4500 Blackwell Comparison

The Verdict

The database comparison between the Intel Arc G3 Extreme and the NVIDIA RTX PRO 4500 Blackwell is defined by a massive performance gulf. The Arc G3 Extreme is an integrated graphics processor (IGP) with no recorded benchmark scores, an average score of zero, and a percentile ranking of 50 among all GPUs. The RTX PRO 4500 Blackwell, by contrast, is a discrete, dual-slot add-in board with recorded scores across nine different tests, an average benchmark score of 31,532, and a percentile ranking of 76. The data shows that the NVIDIA part is the only viable option for any measured graphics workload, while the Intel part serves a fundamentally different role as a portable device component. Any user requiring discrete performance, dedicated VRAM, or workstation-class compute should select the RTX PRO 4500 Blackwell. The Arc G3 Extreme, with its system-shared memory and IGP bus interface, is strictly a low-power integrated solution for devices where a separate graphics card is not an option.

Legacy DirectX tests show scores of 204 in DirectX 10, 320 in DirectX 11, 119 in DirectX 12, and 397 in DirectX 9. The Arc G3 Extreme has no comparable recorded figures, so its performance in these workloads cannot be quantified from the database. The only conclusion available from the recorded data is that the RTX PRO 4500 Blackwell delivers measurable performance across synthetic, compute, and legacy API tests, while the Intel part does not appear in any benchmark result.

The nearest rivals to the RTX PRO 4500 Blackwell provide context for its positioning.

Where Each One Wins

The RTX PRO 4500 Blackwell wins every category where recorded data exists. Its 50.53 TFLOPS of FP32 compute dwarfs the Arc G3 Extreme's 7.680 TFLOPS, indicating a roughly 6.6x raw throughput advantage based on the recorded figures. Pixel rate favors the NVIDIA part at 269.6 GPixel/s versus 60.00 GPixel/s, and texture rate favors it at 789.5 GTexel/s versus 120.0 GTexel/s. The NVIDIA GPU's 32 GB of GDDR7 memory with 896.0 GB/s bandwidth provides dedicated, high-speed storage for large datasets, whereas the Intel GPU's system-shared memory offers no dedicated bandwidth figure and is entirely host dependent. The RTX PRO 4500 Blackwell also includes 328 tensor cores, which the Intel part lacks entirely, making the NVIDIA card the only one of the two with any recorded tensor processing capability.

The Arc G3 Extreme wins on integration and power envelope. Its 80 W TDP is 120 W lower than the RTX PRO 4500 Blackwell's 200 W. It is an IGP with no power connectors and no slot width beyond the integrated form factor, which makes it suitable for portable devices where a dual-slot, 267 mm long, 111 mm tall, 40 mm wide add-in board cannot fit. The NVIDIA card requires a 550 W suggested PSU and a PCIe 5.0 x16 slot, while the Intel part uses the IGP bus interface and draws power from the host system. The Arc G3 Extreme is also fabricated on a smaller 3 nm process compared to the RTX PRO 4500 Blackwell's 5 nm process, although the database does not provide transistor counts or die size for the Intel part to quantify the density difference.

For workstation-class rendering, AI inference, or any workload that uses tensor cores, the RTX PRO 4500 Blackwell is the only choice in this comparison. Its FP16 throughput of 50.53 TFLOPS at a 1:1 ratio means it does not accelerate FP16 relative to FP32, but the absolute figure is still far above the Intel GPU's 15.36 TFLOPS at a 2:1 ratio. For legacy API compatibility, the Passmark DirectX 9 score of 397 and DirectX 11 score of 320 show the NVIDIA GPU handles older workloads, although no comparable data exists for the Intel part. The Arc G3 Extreme's role is limited to portable devices where an integrated GPU is the only option, and its performance in that role cannot be assessed from the database because it has no recorded benchmark scores. The data confirms that the RTX PRO 4500 Blackwell delivers measurable, competitive performance in its class, while the Arc G3 Extreme remains a specification-only entry with no benchmark presence.
