Intel Arc G3 vs NVIDIA GeForce RTX 5070 SUPER Comparison

Intel Arc G3 and NVIDIA GeForce RTX 5070 SUPER occupy opposite ends of the GPU spectrum, with the former designed as an integrated graphics solution for mobile platforms and the latter as a high-performance discrete add-in board. The recorded data shows a fundamental split in their intended use cases, architectural priorities, and physical requirements. The Intel part is an IGP with a 25 W power envelope, while the NVIDIA card is a dual-slot PCIe 5.0 x16 board with a 275 W demand and a 245 mm length. This analysis covers their differing strengths, internal designs, and benchmark positioning based strictly on the database entries.

Where Each One Wins

The Intel Arc G3 wins in scenarios where physical footprint, power draw, and system integration are the primary constraints. Its IGP slot width and bus interface mean it requires no expansion slot, no auxiliary power connectors, and no separate cooling solution. The 25 W TDP allows it to operate within a laptop or compact device's thermal budget, and its display outputs are listed as "Portable Device Dependent," confirming its role in mobile systems. For a thin-and-light device, the Arc G3's 300 MHz base and 2400 MHz boost clocks provide a functional graphics baseline without the need for a discrete card.

The NVIDIA GeForce RTX 5070 SUPER wins in raw graphics throughput, memory bandwidth, and API feature execution. Its benchmark result in 3DMark Steel Nomad DX12 is 2690 points, placing it in the 18th percentile of all GPUs in the database. The Intel Arc G3 has no recorded benchmark scores and sits at the 50th percentile by default, meaning the database contains no direct performance measurements for it. The RTX 5070 SUPER's nearest rivals in the database are all lower-end discrete cards: the NVIDIA Quadro K1100M at 2664 points (1% behind), the NVIDIA GeForce GT 1030 at 2662 points (1.1% behind), the Intel Arc Pro B50 at 2660 points (1.1% behind), and the NVIDIA GeForce GT 440 at 2645 points (1.7% behind). These deltas show that the RTX 5070 SUPER leads this specific cluster by a narrow margin, with its 2690 score representing a 1% advantage over the closest competitor.

For gaming and compute workloads that demand high frame rates, large textures, or heavy ray tracing, the RTX 5070 SUPER's 18 GB GDDR7 memory on a 192-bit bus with 672.0 GB/s bandwidth is the clear choice. The Arc G3's system-shared memory and system-dependent bandwidth mean its performance scales with the host platform's RAM, not with a dedicated VRAM pool. The data indicates no benchmark wins for the Arc G3 in any recorded test, while the RTX 5070 SUPER holds the sole benchmark entry.

Architecture Differences

The Intel Arc G3 uses the Xe3-LPG architecture built on Intel's 3 nm process node, with the chip codenamed Panther Lake. It belongs to the Arc Graphics-M (Panther Lake) generation and is manufactured by Intel. The NVIDIA GeForce RTX 5070 SUPER uses the Blackwell 2.0 architecture on TSMC's 5 nm process, with the chip designated GB205 and belonging to the GeForce 50 generation. The NVIDIA part has 31,100 million transistors on a 263 mm² die, yielding a transistor density of 118.3 million per square millimeter. The Intel part's transistor count and die size are listed as unknown in the database, so no density comparison is possible.

The shading resources differ sharply. The Arc G3 has 1280 shading units, 40 texture mapping units, 20 raster output units, and 10 ray tracing cores. The RTX 5070 SUPER has 6400 shading units, 200 TMUs, 80 ROPs, 50 RT cores, and 200 tensor cores. The Intel part has no tensor core field filled in, while the NVIDIA part includes a dedicated tensor core count for AI acceleration. The Arc G3's pixel rate is 48.00 GPixel/s and its texture rate is 96.00 GTexel/s, versus the RTX 5070 SUPER's 201.0 GPixel/s and 502.4 GTexel/s. The FP32 throughput is 6.144 TFLOPS for Intel and 32.15 TFLOPS for NVIDIA, while the FP16 rates are 12.29 TFLOPS (2:1 ratio) for Intel and 32.15 TFLOPS (1:1 ratio) for NVIDIA.

Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so the API feature set is identical at the specification level. The architectures differ fundamentally in their memory models: the Arc G3 uses system-shared memory with no dedicated VRAM, while the RTX 5070 SUPER uses 18 GB of GDDR7 on a 192-bit interface. The clock behavior also diverges, with the Intel part's base clock at 300 MHz and boost at 2400 MHz, while the NVIDIA part's base is 2325 MHz and boost is 2512 MHz.

Head-to-Head Benchmarks

The database contains only one benchmark result for either GPU, and it belongs to the RTX 5070 SUPER. The 3DMark Steel Nomad DX12 test produced a score of 2690, with an average benchmark score of 2690 across the recorded runs. The Intel Arc G3 has an empty benchmark array and an average score of zero, meaning no comparable measurement exists in the database.

The RTX 5070 SUPER's nearest rivals provide context for its absolute score. The Quadro K1100M trails by 1% with 2664 points, the GT 1030 trails by 1.1% with 2662 points, the Arc Pro B50 trails by 1.1% with 2660 points, and the GT 440 trails by 1.7% with 2645 points. The RTX 5070 SUPER's 2690 score sits at the 18th percentile of all GPUs, which indicates that this specific test result places it in the lower fifth of the database's overall distribution. Without a recorded score for the Arc G3, the head-to-head comparison cannot be quantified; the data only shows that the RTX 5070 SUPER has a measured result and the Arc G3 does not.

The performance gap implied by the specifications is substantial. The RTX 5070 SUPER's FP32 throughput is 32.15 TFLOPS versus the Arc G3's 6.144 TFLOPS, a factor of roughly 5.2 based on the recorded numbers. The texture rate of 502.4 GTexel/s versus 96.00 GTexel/s similarly shows a large advantage for NVIDIA, as does the pixel rate of 201.0 GPixel/s versus 48.00 GPixel/s. These figures come from the database's clock and unit counts, not from direct benchmark comparisons.

Specification Differences

The two GPUs differ in every major specification field except for API support and production status. The process node is 3 nm for Intel versus 5 nm for NVIDIA, with different foundries (Intel versus TSMC). The RTX 5070 SUPER has known transistor and die data (31,100 million and 263 mm²), while the Arc G3's are unknown. The base clock is 300 MHz for Intel and 2325 MHz for NVIDIA, and the boost clock is 2400 MHz for Intel and 2512 MHz for NVIDIA. The NVIDIA memory clock is 1750 MHz with 28 Gbps effective, while the Intel memory clock is listed as "System Shared."

Memory configuration shows the largest split: the Arc G3 has system-shared size, type, bus width, and system-dependent bandwidth, while the RTX 5070 SUPER has 18 GB GDDR7 on a 192-bit bus with 672.0 GB/s. The shading units are 1280 versus 6400, TMUs are 40 versus 200, ROPs are 20 versus 80, RT cores are 10 versus 50, and tensor cores are absent for Intel versus 200 for NVIDIA. The pixel rate is 48.00 GPixel/s versus 201.0 GPixel/s, and the texture rate is 96.00 GTexel/s versus 502.4 GTexel/s. FP32 is 6.144 TFLOPS versus 32.15 TFLOPS, and FP16 is 12.29 TFLOPS (2:1) versus 32.15 TFLOPS (1:1).

The TDP is 25 W for Intel and 275 W for NVIDIA. The slot width is IGP for Intel and dual-slot for NVIDIA. Power connectors are "None" for Intel and "1x 16-pin" for NVIDIA. The bus interface is IGP for Intel and PCIe 5.0 x16 for NVIDIA. Display outputs are "Portable Device Dependent" for Intel and "1x HDMI 2.1b 3x DisplayPort 2.1b" for NVIDIA. The NVIDIA card has physical dimensions of 245 mm length, 115 mm height, and 40 mm width, while the Intel part has no listed dimensions. The release dates differ by five months, with the Arc G3 dated 2026-05-31 and the RTX 5070 SUPER dated 2025-12-31.
