Intel Arc G3 Extreme vs NVIDIA GeForce RTX 5070 Mobile Comparison

The Intel Arc G3 Extreme is an integrated graphics processor built on Intel’s 3 nm Panther Lake chip, using the Xe3-LPG architecture and an 80 W power envelope. The NVIDIA GeForce RTX 5070 Mobile is a discrete-class mobile GPU on TSMC’s 5 nm process, using the Blackwell 2.0 architecture with a 50 W TDP. Both support DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, and both are integrated into portable devices with display outputs dependent on the host laptop. The comparison is heavily one-sided in recorded benchmarks, as the Intel part has no entry in the database’s benchmark suite, while the NVIDIA part has nine recorded scores across multiple APIs.

Head-to-Head Benchmarks

The database contains no matched head-to-head benchmark runs for these two parts. The Intel Arc G3 Extreme has an empty benchmark list and an average benchmark score of zero, meaning there are no recorded performance measurements for it in any of the database’s standard tests. The NVIDIA GeForce RTX 5070 Mobile, by contrast, has a full set of nine benchmark results, including Geekbench OpenCL, Geekbench Vulkan, and seven Passmark tests spanning DirectX 9 through DirectX 12, 2D, 3D, and compute workloads.

The strongest recorded result for the NVIDIA part is in Geekbench OpenCL, where it scores 122238. Its Geekbench Vulkan result is 116960, which is close behind but still a substantial score. In the Passmark suite, the highest score is the G3D test at 20355, followed by the GPU Compute test at 8279. The DirectX 11 test returns 192, DirectX 9 returns 214, DirectX 10 returns 129, and DirectX 12 returns 93. The 2D test, which measures rasterization and basic drawing performance, returns 896.

Because the Intel part has no recorded scores, there is no direct percentage comparison available between the two. The database’s head-to-head benchmark array is empty, and the win counters show zero wins for each side. This means any analysis of relative performance must rely on the NVIDIA part’s absolute scores and its standing against other GPUs, not on a direct comparison with the Intel part.

The NVIDIA part’s average benchmark score across all recorded tests is 29928. Its percentile rank among all GPUs in the database is 75, meaning it sits above the majority of recorded graphics processors. The Intel part’s percentile rank is 50, which is the median position, but with no benchmark scores to back it up, that percentile likely reflects its position in the database rather than measured performance.

The closest rivals to the NVIDIA part in the database are all desktop GPUs. The NVIDIA GeForce RTX 3070 Ti has an average score of 29945, which is 0.1% higher than the RTX 5070 Mobile. The AMD Radeon RX 6800 averages 30095, 0.6% higher. The NVIDIA GeForce RTX 2080 Ti averages 29783, 0.5% lower. The AMD Radeon RX 6700 averages 30433, 1.7% higher. These deltas are all within roughly two percent, indicating that the RTX 5070 Mobile performs in the same band as these older desktop cards despite being a mobile part with lower power draw.

The FP32 throughput figures are notable. The NVIDIA part delivers 13.13 TFLOPS of FP32 compute, while the Intel part delivers 7.680 TFLOPS. That gives the NVIDIA part roughly 71% more raw single-precision compute on paper. The NVIDIA part also has more texture units, 144 versus 48, and more ROPs, 48 versus 24. Its texture rate is 205.2 GTexel/s versus 120.0 GTexel/s for the Intel part. Pixel rates are closer: 68.40 GPixel/s for NVIDIA versus 60.00 GPixel/s for Intel, a difference of about 14%.

Memory is another major gap. The NVIDIA part uses 8 GB of GDDR7 on a 128-bit bus with 384.0 GB/s of bandwidth. The Intel part uses system shared memory, with bandwidth listed as system dependent and bus width listed as system shared. That means the Intel part’s memory performance is entirely dependent on the host laptop’s DRAM configuration, which is a fundamental disadvantage for bandwidth-heavy workloads.

The Verdict

The recorded data strongly favors the NVIDIA GeForce RTX 5070 Mobile for any measurable performance comparison. It has nine benchmark scores in the database, an average score of 29928, and a percentile rank of 75. The Intel Arc G3 Extreme has no benchmark scores, an average of zero, and a percentile rank of 50. There is no scenario in the recorded data where the Intel part wins a head-to-head test, because no such tests exist and no scores are recorded for it.

The NVIDIA part’s nearest rivals are desktop GPUs from previous generations, and it trades blows with them within a narrow two percent band. Against the RTX 3070 Ti, it is effectively tied at 0.1% lower. Against the RTX 2080 Ti, it is 0.5% higher. Against the RX 6800, it is 0.6% lower. Against the RX 6700, it is 1.7% lower. This suggests that the RTX 5070 Mobile, despite being a 50 W mobile part, delivers desktop-class performance from the previous generation.

The Intel part’s specifications, including 1536 shading units, 48 TMUs, 24 ROPs, and 12 ray tracing cores, are not backed by any recorded benchmark result. Its FP32 rate of 7.680 TFLOPS and pixel rate of 60.00 GPixel/s are the only quantitative performance indicators available, and they trail the NVIDIA part in every category except clock speed. The Intel part boosts to 2500 MHz, while the NVIDIA part boosts to 1425 MHz, but the NVIDIA part’s much larger shader count more than compensates.

For users who need a GPU with proven, recorded performance, the data points exclusively to the NVIDIA part. For users considering the Intel part, the database provides no measured evidence of its performance in any workload. That absence of data is itself the key finding.

Where Each One Wins

The NVIDIA GeForce RTX 5070 Mobile wins in every category where the database has recorded measurements. Its Geekbench OpenCL score of 122238 and Vulkan score of 116960 indicate strong general compute and graphics API performance. Its Passmark G3D score of 20355 places it in a competitive position against desktop GPUs from the previous generation. Its GPU Compute score of 8279 confirms that compute workloads are handled well.

The Intel Arc G3 Extreme has no recorded wins in the database. Its win counter is zero, and its benchmark list is empty. The only areas where it could be considered competitive are not measured: its 2500 MHz boost clock is higher than the NVIDIA part’s 1425 MHz, and its FP16 rate of 15.36 TFLOPS with a 2:1 ratio exceeds its own FP32 rate, but neither of these figures appears in any benchmark result.

The Intel part’s memory architecture is system shared, which means its bandwidth is system dependent. In a laptop with fast dual-channel memory, it could theoretically perform better than the listed figures suggest, but the database records no such configuration. The NVIDIA part’s dedicated 8 GB GDDR7 pool with 384.0 GB/s bandwidth is a fixed, known quantity that does not depend on the host system.

For ray tracing, the NVIDIA part has 36 RT cores, while the Intel part has 12. The NVIDIA part also has 144 tensor cores, while the Intel part has no tensor core count listed. These architectural advantages would likely show up in ray-traced and AI-accelerated workloads, but again, the database has no benchmarks for the Intel part to confirm the magnitude.

The power draw difference is also notable. The NVIDIA part is rated at 50 W, while the Intel part is rated at 80 W. That means the NVIDIA part delivers higher recorded performance while consuming less power. The NVIDIA part also uses a PCIe 5.0 x16 bus interface, while the Intel part uses an integrated graphics processor interface with no external bus.

The memory systems are fundamentally different. The Intel part uses system shared memory with a system dependent bandwidth and bus width. The NVIDIA part has a dedicated 8 GB GDDR7 pool on a 128-bit bus with 384.0 GB/s of bandwidth and a 1500 MHz memory clock with 24 Gbps effective data rate.

The power characteristics are also recorded with different values. The Intel part is rated at 80 W, while the NVIDIA part is rated at 50 W. Both use no external power connectors and have an IGP slot width. The NVIDIA part uses a PCIe 5.0 x16 bus interface, while the Intel part uses an integrated graphics processor interface.

The release dates are different as well. The NVIDIA part was released on 2025-04-14, while the Intel part has a release date of 2026-05-31. Both parts are listed as active in production. The NVIDIA part has a predecessor recorded as GeForce 40 Mobile, while the Intel part has no predecessor or successor listed.

Architecturally, the NVIDIA part supports FP16 at a 1:1 ratio with FP32, both at 13.13 TFLOPS. The Intel part supports FP16 at a 2:1 ratio, delivering 15.36 TFLOPS of FP16 against 7.680 TFLOPS of FP32. The pixel rates are 68.40 GPixel/s for NVIDIA and 60.00 GPixel/s for Intel. The texture rates are 205.2 GTexel/s for NVIDIA and 120.0 GTexel/s for Intel.

The API support is identical across both parts: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs for both are portable device dependent, meaning the actual connectors and supported resolutions depend on the host laptop, not the GPU itself.

The database’s percentile ranks place the NVIDIA part at 75, which is above the median, and the Intel part at 50, which is exactly the median. However, the Intel part’s rank is not supported by any benchmark scores, so it should not be interpreted as measured performance. The NVIDIA part’s rank is supported by nine recorded scores.
