Intel Arc G3 vs NVIDIA GeForce RTX 5070 Mobile Comparison

Intel Arc G3 is an integrated graphics processor built on Intel's Panther Lake platform, using the Xe3-LPG architecture and a 3 nm process. The NVIDIA GeForce RTX 5070 Mobile is a discrete mobile GPU based on the GB206 chip, Blackwell 2.0 architecture, and a 5 nm process fabricated by TSMC. The database contains no direct head-to-head benchmark results between these two parts, so the comparison relies on the recorded specifications and the available benchmark scores for the RTX 5070 Mobile.

Head-to-Head Benchmarks

The database does not include any shared benchmark entries for the Intel Arc G3 and the NVIDIA GeForce RTX 5070 Mobile. The Intel Arc G3 has no recorded benchmark scores and an average benchmark score of zero. The NVIDIA GeForce RTX 5070 Mobile, by contrast, has a substantial set of recorded results across multiple test suites. Its average benchmark score is 29928, placing it at the 75th percentile of all GPUs in the database. The Intel Arc G3 sits at the 50th percentile, a figure derived from its specification profile rather than direct measurement.

The RTX 5070 Mobile's recorded scores show strong performance in compute and graphics workloads. In Geekbench OpenCL, it scores 122238, and in Geekbench Vulkan, it scores 116960. Passmark results include a G3D score of 20355, a GPU compute score of 8279, and DirectX 11 performance at 192. The DirectX 12 score is 93, DirectX 10 is 129, and DirectX 9 is 214. The 2D graphics score is 896. These numbers indicate a capable mobile GPU, but without a corresponding set of Intel Arc G3 results, no direct percentage comparison can be made between the two.

The nearest rivals to the RTX 5070 Mobile in the database provide context for its standing. The NVIDIA GeForce RTX 3070 Ti has an average score of 29945, which is 0.1 percent lower than the RTX 5070 Mobile. The AMD Radeon RX 6800 scores 30095, 0.6 percent higher. The NVIDIA GeForce RTX 2080 Ti scores 29783, which is 0.5 percent lower. The AMD Radeon RX 6700 scores 30433, 1.7 percent higher. These deltas show the RTX 5070 Mobile sits within a tight band of desktop-class GPUs, slightly behind the RX 6700 and RX 6800, and slightly ahead of the RTX 2080 Ti and RTX 3070 Ti. The Intel Arc G3 has no such rival data, so its relative position can only be inferred from its specifications.

Architecture Differences

The two GPUs diverge sharply in their underlying architecture. The Intel Arc G3 uses the Xe3-LPG architecture on a 3 nm process, while the NVIDIA GeForce RTX 5070 Mobile uses Blackwell 2.0 on a 5 nm process. The Intel chip is built in-house by Intel, whereas the RTX 5070 Mobile is fabricated by TSMC. The RTX 5070 Mobile has a known transistor count of 21,900 million on a die size of 181 mm², giving a transistor density of 121.0 million per mm². The Intel Arc G3 lists both transistor count and die size as unknown, so no density figure can be derived.

The compute resources differ by a wide margin. The Intel Arc G3 has 1280 shading units, 40 texture mapping units, 20 raster operation units, and 10 ray tracing cores. The NVIDIA GeForce RTX 5070 Mobile has 4608 shading units, 144 TMUs, 48 ROPs, 36 ray tracing cores, and 144 tensor cores. The Intel part does not list a tensor core count. The RTX 5070 Mobile's shading unit count is 3.6 times higher, and its TMU count is 3.6 times higher as well. The ROP count is 2.4 times higher.

Clock speeds also differ significantly. The Intel Arc G3 runs at a base clock of 300 MHz and a boost clock of 2400 MHz. The RTX 5070 Mobile has a base clock of 907 MHz and a boost clock of 1425 MHz. The memory clocks are fundamentally different: the Intel part uses system shared memory with the clock listed as "System Shared," while the RTX 5070 Mobile has a memory clock of 1500 MHz, described as 24 Gbps effective.

Memory configuration is a major architectural split. The Intel Arc G3 relies on system shared memory, with size, type, bus width, and bandwidth all marked as system dependent. The RTX 5070 Mobile has dedicated 8 GB of GDDR7 memory on a 128 bit bus, with a bandwidth of 384.0 GB/s. This gives the NVIDIA part a fixed and substantial memory bandwidth, while the Intel part's bandwidth is entirely dependent on the host system's memory subsystem.

The bus interface and power profile differ as well. The Intel Arc G3 is an integrated GPU with an IGP bus interface and a 25 W TDP. The RTX 5070 Mobile is also listed as IGP slot width, but it uses a PCIe 5.0 x16 interface and has a 50 W TDP, double the Intel part's power limit. Neither GPU uses external power connectors, and both have display outputs marked as portable device dependent.

The API support is identical on paper: both list DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The performance ceilings, however, are far apart. The Intel Arc G3 delivers 6.144 TFLOPS of FP32 compute and 12.29 TFLOPS of FP16 with a 2:1 ratio. The RTX 5070 Mobile delivers 13.13 TFLOPS of FP32 and 13.13 TFLOPS of FP16 with a 1:1 ratio. The pixel rate for the Intel part is 48.00 GPixel/s, and the texture rate is 96.00 GTexel/s. The RTX 5070 Mobile reaches 68.40 GPixel/s and 205.2 GTexel/s, respectively.

The Verdict

The data from the database shows a clear separation in capability between these two GPUs. The RTX 5070 Mobile has a recorded average benchmark score of 29928 and sits at the 75th percentile, while the Intel Arc G3 has no recorded scores and sits at the 50th percentile based on specifications alone. The RTX 5070 Mobile more than doubles the Intel part's FP32 throughput, with 13.13 TFLOPS versus 6.144 TFLOPS, and offers dedicated 8 GB GDDR7 memory with 384.0 GB/s bandwidth, while the Intel part depends entirely on system memory.

For users who need a discrete GPU with proven benchmark results, the RTX 5070 Mobile is the clear choice. Its score places it within 1.7 percent of the AMD Radeon RX 6700 and 0.6 percent of the RX 6800, and slightly ahead of the RTX 2080 Ti and RTX 3070 Ti. The Intel Arc G3, as an integrated part with a 25 W TDP and no benchmark data, is positioned for a different role, likely in thin and light portable devices where the 50 W TDP and PCIe 5.0 x16 interface of the RTX 5070 Mobile would not be applicable.

The RTX 5070 Mobile also leads in raw resources: 4608 shading units versus 1280, 144 TMUs versus 40, 48 ROPs versus 20, 36 ray tracing cores versus 10, and 144 tensor cores where the Intel part lists none. The pixel rate is 68.40 GPixel/s versus 48.00 GPixel/s, and the texture rate is 205.2 GTexel/s versus 96.00 GTexel/s. The RTX 5070 Mobile has a higher base clock (907 MHz versus 300 MHz) but a lower boost clock (1425 MHz versus 2400 MHz), which is typical of a discrete GPU with a larger die and higher power envelope.

The architecture differences reinforce the performance gap. The RTX 5070 Mobile uses a 21,900 million transistor chip on a 181 mm² die, while the Intel Arc G3 does not disclose these figures. The RTX 5070 Mobile's 50 W TDP is double the Intel part's 25 W TDP, and it requires a PCIe 5.0 x16 connection rather than an integrated bus. The Intel Arc G3 is an integrated GPU, which means its memory bandwidth is system dependent and cannot be compared directly to the fixed 384.0 GB/s of the RTX 5070 Mobile.

The release dates differ as well. The RTX 5070 Mobile was released in 2025, while the Intel Arc G3 is listed for a later release. The RTX 5070 Mobile has a predecessor in the GeForce 40 Mobile series, while the Intel Arc G3 has no listed predecessor or successor.
