Intel Arc G3 vs NVIDIA RTX PRO 4000 Blackwell Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries for the Intel Arc G3 and NVIDIA RTX PRO 4000 Blackwell, so the comparison must be built from the RTX PRO 4000's recorded benchmark scores and the Arc G3's architectural limits. The RTX PRO 4000 Blackwell sits at the 72nd percentile of all GPUs in the database, while the Arc G3 sits at the 50th percentile. That gap alone indicates a substantial performance separation, with the RTX PRO 4000 outpacing the Arc G3 across every measure the database records.

The RTX PRO 4000 Blackwell's average benchmark score is 27,135. Its nearest rivals in the database include the AMD Radeon RX 6700 XT at 27,425 (1.1% ahead), the NVIDIA GeForce RTX 4070 Mobile at 27,435 (1.1% ahead), the NVIDIA GeForce RTX 3090 at 27,565 (1.6% ahead), and the NVIDIA RTX A4000 at 26,683 (1.7% behind). This places the RTX PRO 4000 firmly in the upper-midrange tier, competitive with desktop cards from previous generations.

The Arc G3 has no benchmark scores recorded in the database, with an average benchmark score of exactly 0. Its specification sheet, however, makes the performance gap predictable. The Arc G3 delivers 6.144 TFLOPS of FP32 compute, while the RTX PRO 4000 delivers 36.83 TFLOPS, a 6-fold advantage for the NVIDIA card. The pixel rate tells a similar story: the Arc G3 outputs 48.00 GPixel/s, while the RTX PRO 4000 outputs 197.3 GPixel/s, roughly 4.1 times higher. The texture rate gap is even wider, with the Arc G3 at 96.00 GTexel/s versus the RTX PRO 4000's 575.4 GTexel/s, a 6-fold difference.

The RTX PRO 4000's PassMark G3D score of 28,427 confirms strong rasterization performance.

The 3DMark Steel Nomad DX12 score of 4,648 provides a modern DirectX 12 workload result. The Arc G3 has no comparable entries in the database, so no direct numerical comparison is possible, but the specification gap strongly suggests the RTX PRO 4000 would dominate in every recorded test category.

Architecture Differences

The two GPUs come from fundamentally different design philosophies. The Intel Arc G3 uses the Xe3-LPG architecture on a 3 nm process node, fabricated by Intel itself. It is built around the Panther Lake chip and belongs to the Arc Graphics-M (Panther Lake) generation. This is an integrated graphics processor, as indicated by its IGP slot width, IGP bus interface, and lack of power connectors. It is designed to be part of a mobile processor package, sharing system memory rather than carrying dedicated VRAM.

The NVIDIA RTX PRO 4000 Blackwell uses the Blackwell 2.0 architecture on a 5 nm process node, fabricated by TSMC. It is built around the GB203 chip and belongs to the Blackwell PRO W (x000) generation. This is a discrete workstation card with a single-slot form factor, a PCIe 5.0 x16 interface, and a 16-pin power connector. The database records 45,600 million transistors on a 378 mm² die, resulting in a transistor density of 120.6M per mm². The Arc G3's transistor count, die size, and transistor density are all listed as unknown.

The memory systems could not be more different. The Arc G3 uses shared system memory, with its size, type, and bus width all listed as "System Shared" and bandwidth listed as "System Dependent." The RTX PRO 4000 carries 24 GB of dedicated GDDR7 memory on a 192-bit bus, delivering 672.0 GB/s of bandwidth. This is a fundamental difference in memory architecture: the RTX PRO 4000 has predictable, high-bandwidth VRAM, while the Arc G3's memory performance depends entirely on the host system's RAM configuration.

The compute resources also diverge sharply. The Arc G3 has 1,280 shading units, 40 texture mapping units, 20 render output units, and 10 ray tracing cores. It has no tensor cores listed. The RTX PRO 4000 has 8,960 shading units, 280 TMUs, 96 ROPs, 70 RT cores, and 280 tensor cores. The RTX PRO 4000 has 7 times the shading units, 7 times the TMUs, 4.8 times the ROPs, and 7 times the RT cores. The FP16 ratio also differs: the Arc G3 runs FP16 at a 2:1 rate relative to FP32, reaching 12.29 TFLOPS, while the RTX PRO 4000 runs FP16 at a 1:1 rate, delivering 36.83 TFLOPS.

Clock speeds tell a nuanced story. The Arc G3 has a base clock of 300 MHz and a boost clock of 2,400 MHz. The RTX PRO 4000 has a base clock of 1,230 MHz and a boost clock of 2,055 MHz. The Arc G3 has a higher boost clock, but its dramatically lower base clock and far fewer execution units mean it cannot translate that clock advantage into competitive throughput.

The RTX PRO 4000 was released on March 17, 2025, with a predecessor listed as Workstation Ada. The Arc G3 was released on May 31, 2026. Both are marked as Active in production status. The RTX PRO 4000 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Arc G3 supports the same API set, so software compatibility is not a differentiator.

Where Each One Wins

The RTX PRO 4000 Blackwell is the clear winner in every performance category the database records. Its 36.83 TFLOPS of FP32 compute, 575.4 GTexel/s texture rate, and 197.3 GPixel/s pixel rate position it as a professional workstation and content creation GPU. The 24 GB of GDDR7 memory with 672.0 GB/s bandwidth supports large datasets, high-resolution textures, and GPU compute workloads that require substantial VRAM. Its 280 tensor cores enable AI acceleration, and its 70 RT cores handle ray tracing workloads. The PassMark G3D score of 28,427 and PassMark GPU compute score of 14,805 confirm broad applicability across rasterization and compute tasks. The 3DMark Steel Nomad DX12 score of 4,648 indicates strong performance in modern DirectX 12 games.

The Arc G3 wins in power efficiency and integration. Its 25 W TDP is dramatically lower than the RTX PRO 4000's 140 W TDP. The Arc G3 requires no power connectors and no separate power supply recommendation, while the RTX PRO 4000 requires a 16-pin connector and a 300 W suggested PSU. The Arc G3 is an integrated GPU, meaning it occupies no expansion slot and uses no additional board space. Its display outputs are listed as "Portable Device Dependent," indicating it is designed for laptops and compact mobile systems. The RTX PRO 4000, by contrast, is a 241 mm long, 111 mm tall, 20 mm wide single-slot card with four DisplayPort 2.1b outputs.

The Arc G3 also has a higher boost clock at 2,400 MHz versus 2,055 MHz, though this does not translate into higher throughput given its far smaller execution resource pool. The database shows the Arc G3 at the 50th percentile of all GPUs, which places it at the median, while the RTX PRO 4000 at the 72nd percentile sits well above the median. For workloads that fit within the Arc G3's 6.144 TFLOPS FP32 budget and shared memory constraints, it can handle light productivity, basic 3D rendering, and casual gaming. The RTX PRO 4000 is designed for demanding professional workloads where raw throughput, dedicated memory, and API feature completeness matter more than power draw.

The Verdict

The data presents a one-sided comparison. The NVIDIA RTX PRO 4000 Blackwell outperforms the Intel Arc G3 in every measurable category: compute throughput, pixel rate, texture rate, memory bandwidth, ray tracing cores, tensor cores, and benchmark scores. The RTX PRO 4000's 36.83 TFLOPS FP32 performance, 672.0 GB/s memory bandwidth, and 24 GB of GDDR7 VRAM make it suitable for professional workstation tasks, GPU compute, AI workloads, and demanding content creation. Its benchmark scores confirm this: the PassMark G3D score of 28,427 and 3DMark Steel Nomad DX12 score of 4,648 place it near the AMD Radeon RX 6700 XT, the NVIDIA GeForce RTX 4070 Mobile, and the NVIDIA GeForce RTX 3090 in the database's nearest rivals list.

The Intel Arc G3 serves a completely different purpose. Its 25 W TDP, integrated design, and shared memory architecture make it appropriate for compact mobile devices where power efficiency and physical footprint matter more than raw performance. Its 6.144 TFLOPS FP32 compute and 10 ray tracing cores provide entry-level graphics capability, but the lack of dedicated VRAM and the system-dependent memory bandwidth limit its usefulness for professional workloads.

Users who need a discrete workstation GPU with dedicated memory, high compute throughput, and professional feature support should select the RTX PRO 4000 Blackwell. Users who need integrated graphics in a low-power mobile processor package should consider the Arc G3. The RTX PRO 4000 is the only one of the two with recorded benchmark results, and those results show a GPU that competes with desktop cards from the previous generation. The Arc G3's specifications indicate a capable integrated solution, but the database contains no performance measurements to validate its real-world behavior.
