Intel Arc G3 vs NVIDIA RTX PRO 2000 Blackwell Comparison

Where Each One Wins

The recorded data splits these two GPUs into entirely different performance classes. The NVIDIA RTX PRO 2000 Blackwell holds every benchmark win in the database, with a comprehensive set of scores across DirectX, compute, and general workloads. The Intel Arc G3 has no recorded benchmark entries, meaning its average benchmark score sits at zero and its percentile versus all GPUs is 50. The NVIDIA part, by contrast, posts an average benchmark score of 25269 and sits at the 70th percentile, which places it above the midpoint of all tracked GPUs.

The Intel Arc G3 is positioned as an integrated graphics processor, using system shared memory and drawing power from the host platform. Its role is fundamentally different: it is an IGP with a 25 W TDP, designed for portable devices where the display outputs are device dependent. The NVIDIA RTX PRO 2000 Blackwell is a dual-slot, 70 W discrete workstation card with its own 16 GB GDDR7 memory and a dedicated 288.0 GB/s memory bus. The use-case split is therefore clear: the Intel part serves integrated scenarios with modest expectations, while the NVIDIA part serves professional workstation workloads that demand sustained throughput.

In terms of raw compute, the NVIDIA card delivers 17.03 TFLOPS FP32 and 17.03 TFLOPS FP16 (1:1), while the Intel IGP offers 6.144 TFLOPS FP32 and 12.29 TFLOPS FP16 (2:1). That is a 2.77x advantage for NVIDIA in FP32 throughput. The gap narrows for FP16 but NVIDIA still leads by roughly 1.39x. For professional applications that rely on single-precision compute, the NVIDIA part is decisively ahead. The Intel part's FP16 advantage relative to its own FP32 figure indicates a 2:1 ratio, which is typical for consumer-oriented integrated graphics, but the absolute numbers remain lower.

The NVIDIA card also dominates in memory bandwidth. It has 288.0 GB/s of dedicated bandwidth via a 128-bit GDDR7 interface, whereas the Intel part's bandwidth is system dependent and its memory bus is shared with the host. For workloads that stream large datasets, such as neural network inference or large 3D scenes, the NVIDIA card's dedicated memory subsystem is a substantial advantage. The Intel IGP's performance will vary with the host system's RAM configuration, making it less predictable in professional settings.

Head-to-Head Benchmarks

Since the Intel Arc G3 has no entries in the benchmark database, every head-to-head comparison defaults to the NVIDIA RTX PRO 2000 Blackwell's recorded scores. The NVIDIA card's strongest result comes from Geekbench Vulkan, where it scores 113865. Its Geekbench OpenCL score is 106087, showing strong cross-API compute performance. In Passmark G3D, the card scores 20049, while its Passmark GPU Compute score is 8396. These figures place the card well above the median GPU in the database, consistent with its 70th percentile ranking.

The Passmark DirectX results show a notable spread across API generations. The card scores 241 in DirectX 9, 174 in DirectX 11, 122 in DirectX 10, and only 80 in DirectX 12. This pattern suggests that the card's performance is more optimized for legacy DirectX workloads in the Passmark suite, or that the Passmark DirectX 12 test is less favorable to this architecture. The 3DMark Steel Nomad DX12 score of 2374.5 provides a separate, modern DirectX 12 measurement that indicates capable performance in current-generation game engines.

The nearest rival data contextualizes the NVIDIA card's position. The AMD Radeon RX 6700M posts an average score of 25633, which is 1.4% higher than the NVIDIA card's 25269. The AMD Radeon Pro W5700 scores 25726, 1.8% higher. The NVIDIA GeForce RTX 3080 Ti Mobile also scores 25740, 1.8% higher. The NVIDIA RTX A5000 Mobile scores 24763, which is 2.0% lower than the RTX PRO 2000 Blackwell. This places the RTX PRO 2000 Blackwell in a tight cluster, slightly below three mobile gaming and workstation parts but ahead of one professional mobile card.

The Intel Arc G3's absence from the benchmark suite means no direct numerical comparison is possible. Its 50th percentile ranking is a default value that reflects no recorded performance data, not a measured result. Any assessment of the Intel part must rely on its specifications: 1280 shading units, 40 TMUs, 20 ROPs, 10 RT cores, and a 2400 MHz boost clock. These specifications indicate an entry-level integrated solution, but without benchmark scores, the database cannot quantify its real-world performance.

Specification Differences

The two GPUs differ across nearly every measurable specification. The Intel Arc G3 uses a 3 nm process node at Intel's foundry, while the NVIDIA card uses a 5 nm node at TSMC. NVIDIA's transistor count is recorded at 21,900 million on a 181 mm² die, giving a density of 121.0M per mm². Intel's transistor count and die size are listed as unknown.

Clock speeds diverge sharply. The Intel part has a base clock of 300 MHz and a boost of 2400 MHz. The NVIDIA card has a base of 982 MHz and a boost of 1957 MHz. Despite the lower boost clock, the NVIDIA card achieves much higher throughput due to its larger shader count: 4352 vs 1280. The NVIDIA card also has 136 TMUs vs 40, 48 ROPs vs 20, 34 RT cores vs 10, and 136 tensor cores vs none listed on the Intel part.

Memory is a fundamental differentiator. The Intel Arc G3 uses system shared memory with no dedicated VRAM, no fixed bus width, and bandwidth that depends on the host system. The NVIDIA card has 16 GB of GDDR7, a 128-bit bus, and 288.0 GB/s of fixed bandwidth. The memory clock on the NVIDIA card is 1125 MHz with 18 Gbps effective. The Intel part's memory clock is also system dependent.

Form factor and power differ completely. The Intel part is an IGP with no slot width, no power connectors, and a 25 W TDP. The NVIDIA card is dual-slot, 167 mm long, 69 mm high, and 20 mm wide, with no power connectors but a suggested PSU of 250 W and a 70 W TDP. The bus interface is IGP for Intel and PCIe 5.0 x8 for NVIDIA. Display outputs are portable device dependent for Intel, while NVIDIA provides 4x mini-DisplayPort 2.1b.

Architecture Differences

The Intel Arc G3 is built on the Xe3-LPG architecture, part of the Arc Graphics-M generation for Panther Lake. This is an integrated architecture designed for low power consumption within a 25 W envelope. The Xe3-LPG architecture supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Its FP16 throughput of 12.29 TFLOPS at a 2:1 ratio indicates a consumer-oriented design that can accelerate half-precision workloads but prioritizes power efficiency over raw compute.

The NVIDIA RTX PRO 2000 Blackwell uses the Blackwell 2.0 architecture, built on the GB206 chip, and belongs to the Blackwell PRO W (x000) generation. This is a discrete workstation architecture with a 70 W TDP. It includes 136 tensor cores, which are absent from the Intel part's specification list. The tensor cores enable dedicated AI and deep learning acceleration, a feature set that the Intel IGP does not advertise. The NVIDIA card's FP16 performance is 17.03 TFLOPS at a 1:1 ratio, meaning it does not rely on a packed-to-FP32 conversion rate; it delivers full-rate FP16.

The NVIDIA card's predecessor is listed as Workstation Ada, indicating a direct lineage in the professional workstation segment. The Intel part has no predecessor or successor listed. Both support the same API set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA card's release date is recorded as 2025-08-10, while the Intel part's release date is 2026-05-31, making the Intel part newer by roughly nine months.

The 5 nm TSMC process on the NVIDIA card allows for a high transistor density of 121.0M per mm². The Intel part's 3 nm process at Intel's own foundry is a newer node, but without transistor or die size data, the density cannot be compared. The NVIDIA card's 21,900 million transistors on a 181 mm² die indicate a large, complex chip. The Intel part's unknown transistor count makes architectural comparison incomplete, but the shading unit count alone (1280 vs 4352) suggests a much smaller execution footprint.

The Verdict

The data supports a clear verdict: the NVIDIA RTX PRO 2000 Blackwell is the superior performer in every measured category, while the Intel Arc G3 serves a fundamentally different purpose. The NVIDIA card's 17.03 TFLOPS FP32 is nearly three times the Intel part's 6.144 TFLOPS. Its 288.0 GB/s dedicated memory bandwidth is not only higher but also fixed and predictable, unlike the Intel part's system dependent bandwidth. The NVIDIA card's 34 RT cores and 136 tensor cores provide dedicated hardware for ray tracing and AI workloads, neither of which the Intel part matches in count or capability.

The benchmark database records zero results for the Intel Arc G3. Its 50th percentile ranking is a placeholder, not a measurement. The NVIDIA card, by contrast, has ten recorded benchmark scores and a 70th percentile ranking, with an average score of 25269 that places it within 2% of several strong mobile and workstation rivals. The NVIDIA card's nearest rival data shows it is 2.0% ahead of the RTX A5000 Mobile and within 1.8% of the GeForce RTX 3080 Ti Mobile, indicating that it performs at a competitive level for its class.

For users selecting between these two, the choice is dictated by form factor and workload. The Intel Arc G3 is an integrated solution for portable devices, with a 25 W TDP and no dedicated memory. It is suitable for basic graphics and compute within a constrained power envelope. The NVIDIA RTX PRO 2000 Blackwell is a discrete workstation card with 16 GB of GDDR7, a 70 W TDP, and a dual-slot footprint. It is designed for professional applications that require sustained FP32 throughput, dedicated ray tracing, and tensor core acceleration. The data shows no scenario where the Intel part outperforms the NVIDIA card, and the NVIDIA card's benchmark results confirm its workstation-grade capability. The Intel part's value lies in its integration and low power draw, not in competitive performance against a discrete 70 W card.
