Intel Arc Pro B390 vs NVIDIA GeForce RTX 4070 GDDR6 Comparison

The Verdict

The recorded data presents two fundamentally different products. The Intel Arc Pro B390 is an integrated graphics processor (IGP) built on a 3 nm process, while the NVIDIA GeForce RTX 4070 GDDR6 is a discrete, dual-slot add-in card. The database shows the RTX 4070 GDDR6 holds a decisive performance advantage in the one recorded 3DMark Steel Nomad DX12 test, scoring 4334.5 points. The Arc Pro B390 has no recorded benchmark scores, an average benchmark score of zero, and sits at the 50th percentile among all GPUs. The RTX 4070 GDDR6, despite its higher raw capability, sits at the 25th percentile, which reflects the distribution of all recorded GPUs in the database rather than its absolute capability.

For users requiring a discrete graphics card with dedicated memory, the RTX 4070 GDDR6 is the only option with measured gaming performance data. The Arc Pro B390, with its system-shared memory and integrated design, suits systems where no expansion slot or external power connector is available. The RTX 4070 GDDR6 requires a 550 W suggested power supply and a 16-pin connector. The Arc Pro B390 draws 80 W and uses no power connectors. The data indicates these products target separate market segments. The RTX 4070 GDDR6 is end-of-life, while the Arc Pro B390 remains in active production.

Architecture Differences

The two GPUs use completely different architectures and manufacturing approaches. Intel builds the Arc Pro B390 on a 3 nm process at Intel foundries, using the Xe3-LPG architecture. The chip is codenamed Panther Lake and belongs to the Arc Graphics-WM generation. NVIDIA manufactures the RTX 4070 GDDR6 on a 5 nm process at TSMC, using the Ada Lovelace architecture with the AD104 chip. The RTX 4070 GDDR6 contains 35,800 million transistors on a 294 mm² die, with a transistor density of 121.8M per mm². The Arc Pro B390's transistor count and die size are listed as unknown in the database.

The Arc Pro B390 integrates 1,536 shading units, 48 texture mapping units, 24 raster output pipelines, and 12 ray tracing cores. It has no dedicated tensor core count listed. The RTX 4070 GDDR6 fields 5,888 shading units, 184 TMUs, 64 ROPs, 46 ray tracing cores, and 184 tensor cores. These resource counts explain the large gap in raw throughput. The Arc Pro B390 delivers 7.680 TFLOPS FP32 and 15.36 TFLOPS FP16 with a 2:1 ratio. The RTX 4070 GDDR6 delivers 29.15 TFLOPS FP32 and the same 29.15 TFLOPS FP16 at a 1:1 ratio.

Memory architecture differs completely. The Arc Pro B390 uses system-shared memory with system-dependent bandwidth. The RTX 4070 GDDR6 carries 12 GB of GDDR6 memory on a 192-bit bus, delivering 480.0 GB/s bandwidth. Clock behavior also differs. The Arc Pro B390 has a 300 MHz base clock and a 2,500 MHz boost clock. The RTX 4070 GDDR6 starts at 1,920 MHz base and boosts to 2,475 MHz. Memory clocks are 2,500 MHz with 20 Gbps effective for the NVIDIA card, while the Intel part lists system-shared memory.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX 4070 GDDR6 connects via PCIe 4.0 x16 and outputs 1x HDMI 2.1 and 3x DisplayPort 1.4a. The Arc Pro B390 uses an IGP bus interface with portable-device-dependent display outputs. Physical dimensions underline the divide: the RTX 4070 GDDR6 measures 240 mm in length, 110 mm in height, and 40 mm in width, while the Arc Pro B390 has no listed dimensions.

Head-to-Head Benchmarks

The database contains one recorded benchmark for the RTX 4070 GDDR6 and none for the Arc Pro B390. In 3DMark Steel Nomad DX12, the RTX 4070 GDDR6 scores 4334.5 points. The average benchmark score for the NVIDIA card is 4335. The Arc Pro B390 has an average benchmark score of zero, meaning no comparable measurement exists in the database.

The RTX 4070 GDDR6's nearest rivals in the database are all low-end or older parts. The Intel Iris Pro Graphics 5200 scores 4360, which is 0.6% above the RTX 4070 GDDR6. The NVIDIA GeForce 930M scores 4388, 1.2% higher. The AMD FirePro W2100 scores 4295, 0.9% below. The NVIDIA GeForce GTX 460M scores 4282, 1.2% below. These deltas place the RTX 4070 GDDR6 within a tight cluster around 4,300 points, despite its much larger shading unit count and memory bandwidth. The recorded data suggests the single Steel Nomad result may not represent the card's full capability, as the percentile ranking of 25 among all GPUs contradicts the raw resource advantage.

Texture and pixel throughput figures favor the RTX 4070 GDDR6 substantially. The NVIDIA card achieves 455.4 GTexel/s versus 120.0 GTexel/s for the Intel part, a 3.8 times advantage. Pixel rate reaches 158.4 GPixel/s versus 60.00 GPixel/s, a 2.64 times advantage. FP32 throughput of 29.15 TFLOPS versus 7.680 TFLOPS represents the same 3.8 times gap. The RTX 4070 GDDR6 also matches FP16 to FP32 at 29.15 TFLOPS, whereas the Arc Pro B390 halves FP16 to 15.36 TFLOPS.

Where Each One Wins

The RTX 4070 GDDR6 wins on every measured performance axis. It has 3.8 times the shading units, 3.8 times the TMUs, 2.7 times the ROPs, 3.8 times the ray tracing cores, and 184 tensor cores versus none listed. It delivers 3.8 times the FP32 throughput, 3.8 times the texture rate, 2.64 times the pixel rate, and 480.0 GB/s of dedicated bandwidth versus system-dependent shared memory. The 12 GB GDDR6 frame buffer allows local data storage without competing with system RAM. The PCIe 4.0 x16 interface provides a standard expansion path, and the display outputs support multiple external monitors directly.

The Arc Pro B390 wins on power efficiency and integration. Its 80 W TDP is 120 W lower than the RTX 4070 GDDR6's 200 W. It requires no power connectors and no additional PCIe slot, as it is an IGP. The 3 nm process node gives it a manufacturing advantage in density, although transistor count remains unknown. Its 2,500 MHz boost clock is 25 MHz higher than the NVIDIA card. The Arc Pro B390's active production status and 2026 release date indicate current availability, while the RTX 4070 GDDR6 is end-of-life.

For systems with limited space or power budgets, the Arc Pro B390 eliminates the need for a discrete card entirely. For applications requiring measured 3D performance, the RTX 4070 GDDR6 provides the only recorded benchmark data, with a 4334.5 Steel Nomad score. The database shows no head-to-head benchmark results between these two GPUs, so direct comparative measurements remain unavailable. The wins for each product are defined by the recorded specifications: the NVIDIA card dominates raw compute and memory metrics, while the Intel part offers lower power draw, integrated form factor, and a newer manufacturing process.
