Intel Arc G3 vs NVIDIA GeForce RTX 4070 Comparison

Head-to-Head Benchmarks

The recorded data presents an unusual comparison. The Intel Arc G3 has no benchmark scores in the database, while the NVIDIA GeForce RTX 4070 has a substantial set of recorded measurements. This means the head-to-head analysis is necessarily one-sided, drawing on the RTX 4070's results and the Arc G3's theoretical specifications.

The RTX 4070 posts an average benchmark score of 37,648 across all recorded tests. Its percentile ranking sits at 81, placing it in the upper fifth of all GPUs tracked by the database. The Arc G3, by contrast, has a percentile ranking of 50, indicating a median position, and its average benchmark score is recorded as zero due to the absence of test data.

Looking at the RTX 4070's individual results, the strongest showing comes from the Geekbench Vulkan test, where it scores 174,152. The Geekbench OpenCL result is close behind at 154,858. In the Passmark suite, the G3D test delivers a score of 26,927, while the GPU Compute test reaches 14,720. The DirectX 11 test produces a score of 244, with DirectX 9 at 320 and DirectX 10 at 139. The DirectX 12 result is the lowest of the DirectX tests at 103. The Passmark G2D score, which measures 2D graphics performance, is 1,164.

The RTX 4070's nearest rivals in the database provide context for these numbers. The NVIDIA Tesla P4 averages 37,628, just 0.1% below the RTX 4070. The AMD Radeon RX Vega 56 averages 37,507, a 0.4% gap. The NVIDIA GeForce RTX 4080 Mobile averages 38,135, which is 1.3% higher than the RTX 4070. The AMD Radeon PRO W6400 averages 37,157, putting it 1.3% lower. These tight margins show the RTX 4070 sits in a competitive cluster, though the data does not provide comparable scores for the Arc G3.

Since the Arc G3 has no benchmark entries, the database offers no measured wins for either side. The wins counter records zero for both products. Any performance assessment for the Arc G3 must therefore rely on its architectural specifications rather than empirical results.

Architecture Differences

The two GPUs come from different manufacturers and use entirely distinct design approaches. The Intel Arc G3 is built on the Panther Lake chip with the Xe3-LPG architecture, part of the Arc Graphics-M generation. It uses a 3 nm process node manufactured by Intel itself. The NVIDIA GeForce RTX 4070 uses the AD104 chip with the Ada Lovelace architecture, part of the GeForce 40 series. It is built on a 5 nm process at TSMC. The process node difference is notable: the Arc G3 uses a smaller 3 nm node, which typically allows for higher transistor density and better power efficiency per area, though the RTX 4070's larger node is offset by a much bigger chip.

The RTX 4070 contains 35,800 million transistors on a die size of 294 mm², giving a transistor density of 121.8 million per mm². The Arc G3's transistor count and die size are listed as unknown in the database. This makes direct comparisons of physical scale impossible, but the specifications reveal a significant difference in resource allocation.

The Arc G3 has 1,280 shading units, 40 texture mapping units, and 20 raster output units. The RTX 4070 has 5,888 shading units, 184 texture mapping units, and 64 raster output units. These numbers indicate the RTX 4070 has roughly 4.6 times the shading units, 4.6 times the texture units, and 3.2 times the raster units. The RTX 4070 also has 46 ray tracing cores and 184 tensor cores, while the Arc G3 has 10 ray tracing cores and no tensor cores listed.

Clock speeds differ as well. The Arc G3 runs at a base clock of 300 MHz with a boost clock of 2,400 MHz. The RTX 4070 has a base clock of 1,920 MHz and a boost clock of 2,475 MHz. The boost clocks are close, but the base clocks are drastically different, with the RTX 4070 starting much higher.

The resulting throughput figures reflect these differences. The RTX 4070 achieves 158.4 GPixel/s in pixel rate and 455.4 GTexel/s in texture rate. The Arc G3 manages 48.00 GPixel/s and 96.00 GTexel/s respectively. In floating point performance, the RTX 4070 delivers 29.15 TFLOPS for both FP32 and FP16, with a 1:1 ratio. The Arc G3 delivers 6.144 TFLOPS for FP32 and 12.29 TFLOPS for FP16, using a 2:1 ratio. The RTX 4070's FP32 output is approximately 4.7 times higher.

Memory configurations are fundamentally different. The Arc G3 uses system shared memory, with its size, type, and bus width all listed as system dependent. Its bandwidth depends on the host system. The RTX 4070 has 12 GB of dedicated GDDR6X memory on a 192-bit bus, delivering 504.2 GB/s of bandwidth. The memory clock is 1,313 MHz, translating to 21 Gbps effective.

Power characteristics also diverge sharply. The Arc G3 has a TDP of 25 W and uses no power connectors, since it is an integrated graphics processor (IGP). The RTX 4070 has a TDP of 200 W, uses a single 16-pin power connector, and requires a suggested power supply of 550 W. The Arc G3's slot width is listed as IGP, while the RTX 4070 is a dual-slot card measuring 240 mm in length, 110 mm in height, and 40 mm in width.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs differ: the Arc G3's outputs are portable device dependent, while the RTX 4070 offers 1x HDMI 2.1 and 3x DisplayPort 1.4a.

The Verdict

The data shows two products aimed at entirely different segments. The Intel Arc G3 is an integrated GPU with a 25 W TDP, designed for portable devices where power consumption is critical. The NVIDIA GeForce RTX 4070 is a discrete, dual-slot graphics card with a 200 W TDP, a dedicated 12 GB memory pool, and a 550 W suggested power supply.

Benchmark results confirm the RTX 4070 performs at a high level, with an average score of 37,648 and a percentile ranking of 81. Its nearest rivals all fall within a 1.3% band, indicating it is a well-positioned mid-to-high-end card. The Arc G3 has no recorded benchmarks, so its real-world performance cannot be confirmed from the database.

For users who need a dedicated graphics card for demanding workloads, the RTX 4070 is the only option with measured data. Its 29.15 TFLOPS FP32 performance, 504.2 GB/s memory bandwidth, and 46 ray tracing cores provide a substantial hardware foundation. The Arc G3's 6.144 TFLOPS FP32 and system-dependent memory place it in a much lower performance tier, suitable for basic graphics tasks in compact devices.

The RTX 4070 is listed as end-of-life, with the GeForce 50 series as its successor. The Arc G3 is listed as active production. This suggests the Intel product is current, while the NVIDIA product is being phased out, though the RTX 4070 remains available in the market with a launch MSRP of 599 USD.

Where Each One Wins

The NVIDIA GeForce RTX 4070 wins in every category where measured data exists. Its 29.15 TFLOPS FP32 performance is roughly 4.7 times the Arc G3's 6.144 TFLOPS. Its texture rate of 455.4 GTexel/s is more than 4.7 times the Arc G3's 96.00 GTexel/s. Its pixel rate of 158.4 GPixel/s is more than 3.3 times the Arc G3's 48.00 GPixel/s.

The RTX 4070 also wins on memory. Its 504.2 GB/s dedicated bandwidth vastly exceeds the Arc G3's system-dependent shared memory. The 12 GB dedicated frame buffer allows for higher resolution textures and larger datasets without competing with the CPU for system memory.

The RTX 4070's 184 tensor cores provide dedicated AI acceleration hardware, which the Arc G3 lacks entirely. Its 46 ray tracing cores also outnumber the Arc G3's 10, giving it a substantial advantage in ray-traced workloads.

The Intel Arc G3 wins on power efficiency. Its 25 W TDP is one-eighth of the RTX 4070's 200 W. It requires no power connectors and no separate power supply recommendation. It is an integrated GPU, meaning it occupies no expansion slot and adds no physical footprint to a device. For battery-powered portable devices, this makes it the only viable option between the two.

The Arc G3 also wins on production status. It is listed as active, while the RTX 4070 is end-of-life. The RTX 4070's successor, the GeForce 50 series, is already recorded in the database.
