Intel Arc G3 vs NVIDIA RTX 2000 Max-Q Ada Generation Comparison

The Verdict

The database records two mobile graphics solutions aimed at thin-and-light portable workstations, yet the data positions them very differently. The Intel Arc G3 is an integrated graphics processor built into Intel's Panther Lake silicon, using the Xe3-LPG architecture on Intel's 3 nm process. The NVIDIA RTX 2000 Max-Q Ada Generation is a discrete part with its own dedicated memory, built on TSMC's 5 nm process with the AD107 chip. Both occupy the 50th percentile among all GPUs in the database, and both show an average benchmark score of zero, meaning no direct measured performance figures are available for either. The deciding factors between them, based solely on the recorded specifications, come down to architecture, memory configuration, compute resources, and power envelope.

For workloads that depend on large, fast, dedicated memory and higher raw throughput, the NVIDIA part has the structural advantage. It provides 8 GB of GDDR6 on a 128-bit bus with 256.0 GB/s of bandwidth, compared to the Intel part's system-shared memory with bandwidth described simply as "System Dependent". The NVIDIA GPU also carries 3072 shading units, 96 texture mapping units, 48 render output units, 24 ray tracing cores, and 96 tensor cores. The Intel Arc G3 has 1280 shading units, 40 TMUs, 20 ROPs, and 10 ray tracing cores, with no tensor cores listed. These are substantial gaps in raw compute resources.

For systems where power draw and integration are the primary constraints, the Intel part presents a different profile. It runs at a 25 W TDP, while the NVIDIA part runs at 35 W. The Intel GPU is an IGP with no power connectors and a system-shared memory interface, meaning it draws no additional power for dedicated VRAM and occupies no separate bus slot. The NVIDIA part, while also listed as IGP slot width and having no power connectors, uses a PCIe 4.0 x16 bus interface, which indicates a separate device on the board. The choice between them, strictly from the data, is one of dedicated memory and higher compute capacity against lower power draw and full integration into the host processor.

Architecture Differences

The Intel Arc G3 is built on the Xe3-LPG architecture, fabricated on Intel's 3 nm process at Intel's own foundry. It belongs to the Arc Graphics-M generation under the Panther Lake chip family. The transistor count and die size are not recorded in the database, so no density comparison is possible. The NVIDIA RTX 2000 Max-Q Ada Generation uses the Ada Lovelace architecture, fabricated on TSMC's 5 nm process. Its AD107 chip contains 18,900 million transistors on a 159 mm² die, yielding a transistor density of 118.9 million transistors per mm². This is the only recorded density figure between the two.

The memory subsystems diverge completely. The Intel part uses system-shared memory, with the size, type, bus width, and bandwidth all listed as "System Shared" or "System Dependent". This means the GPU borrows from the host's main memory, and its bandwidth varies with the rest of the system. The NVIDIA part has 8 GB of dedicated GDDR6 memory on a 128-bit bus, delivering a fixed 256.0 GB/s of bandwidth. The clock rates also differ sharply. The Intel GPU has a base clock of 300 MHz and a boost clock of 2400 MHz. The NVIDIA GPU has a base clock of 930 MHz and a boost clock of 1455 MHz. The Intel part boosts much higher, but the NVIDIA part starts at a much higher base.

Compute resources show a significant NVIDIA advantage. The RTX 2000 Max-Q Ada has 3072 shading units, 96 TMUs, 48 ROPs, 24 RT cores, and 96 tensor cores. The Arc G3 has 1280 shading units, 40 TMUs, 20 ROPs, and 10 RT cores, with no tensor core count recorded. The NVIDIA part also lists a 1:1 FP16 to FP32 ratio, meaning its half-precision and single-precision rates are identical at 8.940 TFLOPS each. The Intel part lists a 2:1 ratio, with FP16 at 12.29 TFLOPS and FP32 at 6.144 TFLOPS. This suggests the Intel design uses paired FP16 execution, while the NVIDIA design has dedicated FP16 paths.

The API support is identical across both products: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both are listed as Active in production status. The NVIDIA part has a predecessor and successor recorded as Ampere-MW and Blackwell-MW respectively, while the Intel part lists none. The NVIDIA part was released on 2023-03-20, while the Intel part has a release date of 2026-05-31. Neither product has a recorded launch MSRP.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark results for these two products. Both have an average benchmark score of zero, and both sit at the 50th percentile among all GPUs. The winsA and winsB counters are both zero. Without measured performance data, the comparison must rely entirely on the recorded architectural specifications.

The FP32 throughput comparison is the clearest numerical gap. The NVIDIA part delivers 8.940 TFLOPS of single-precision compute, which is 45.4% higher than the Intel part's 6.144 TFLOPS. In texture throughput, the NVIDIA part reaches 139.7 GTexel/s against the Intel part's 96.00 GTexel/s, a 45.5% advantage. In pixel throughput, the NVIDIA part delivers 69.84 GPixel/s against 48.00 GPixel/s, a 45.5% edge. These three ratios are consistent because the NVIDIA part has exactly 2.4 times the shading units, TMUs, and ROPs of the Intel part, and its boost clock is lower, which narrows the raw count advantage to roughly 45% in each metric.

The FP16 comparison flips the direction. The Intel part's FP16 throughput of 12.29 TFLOPS is 37.5% higher than the NVIDIA part's 8.940 TFLOPS. This is a direct consequence of the Intel architecture's 2:1 FP16 to FP32 ratio, which allows half-precision execution to run at twice the single-precision rate. The NVIDIA part's 1:1 ratio means its FP16 rate equals its FP32 rate. For workloads that use half-precision math, the Intel part has a recorded numerical advantage despite having fewer shading units overall.

The ray tracing comparison shows a resource gap. The NVIDIA part has 24 RT cores, while the Intel part has 10. The NVIDIA part also has 96 tensor cores, while the Intel part records none. The database does not provide RT core clock speeds or efficiency metrics, so the raw count is the only available comparison. The memory bandwidth comparison is even more lopsided: 256.0 GB/s for the NVIDIA part versus "System Dependent" for the Intel part. Since the Intel GPU shares system memory, its bandwidth is not fixed in the database.

The power efficiency comparison requires noting the TDP figures. The NVIDIA part draws 35 W and delivers 8.940 TFLOPS FP32, which is 0.255 TFLOPS per watt. The Intel part draws 25 W and delivers 6.144 TFLOPS FP32, which is 0.246 TFLOPS per watt. The NVIDIA part's FP32 efficiency is 3.7% higher per watt. For FP16, the Intel part delivers 12.29 TFLOPS at 25 W, which is 0.492 TFLOPS per watt, while the NVIDIA part delivers 8.940 TFLOPS at 35 W, which is 0.255 TFLOPS per watt. The Intel part's FP16 efficiency is 92.9% higher per watt. These figures are derived directly from the recorded TDP and throughput values.
