Intel Arc Pro B390 vs NVIDIA GeForce RTX 5070 SUPER Comparison

Where Each One Wins

The recorded data splits these two products into completely different usage classes. The Intel Arc Pro B390 is an integrated graphics processor (IGP) designed for portable devices, with system-shared memory and no dedicated power connectors. Its benchmark presence is effectively absent from the database, showing a 50th percentile standing among all GPUs and no recorded benchmark scores. The NVIDIA GeForce RTX 5070 SUPER, by contrast, is a discrete dual-slot add-in card with 18 GB of dedicated GDDR7 memory, a PCIe 5.0 x16 interface, and a recorded 3DMark Steel Nomad DX12 score of 2690 points.

The RTX 5070 SUPER occupies the 18th percentile among all GPUs in the database, which places it ahead of roughly 82 percent of recorded graphics hardware. Its nearest rivals in the database are the NVIDIA Quadro K1100M at 2664 points (1 percent behind), the NVIDIA GeForce GT 1030 at 2662 points (1.1 percent behind), the Intel Arc Pro B50 at 2660 points (1.1 percent behind), and the NVIDIA GeForce GT 440 at 2645 points (1.7 percent behind). These margins are small in percentage terms, but the RTX 5070 SUPER still leads every one of its listed nearest rivals in the Steel Nomad workload.

The Intel Arc Pro B390 wins in the categories of power draw and physical footprint. Its 80 W TDP is dramatically lower than the 275 W TDP of the RTX 5070 SUPER. As an IGP, it consumes no expansion slot, requires no external power connector, and has no separate card dimensions. The RTX 5070 SUPER requires a dual-slot cooler, a 16-pin power connector, and measures 245 mm by 115 mm by 40 mm. For systems where space and thermal headroom are constrained, the B390 is the only viable option between the two.

Architecture Differences

The Intel Arc Pro B390 uses the Panther Lake chip with the Xe3-LPG architecture, built on Intel's 3 nm process node. It belongs to the Arc Graphics-WM (Panther Lake) generation and succeeds HD Graphics-WM. The RTX 5070 SUPER uses the GB205 chip with the Blackwell 2.0 architecture, built on TSMC's 5 nm process. It belongs to the GeForce 50 series generation.

The B390 integrates 1536 shading units, 48 texture mapping units, 24 raster operation units, and 12 ray tracing cores. It reports no dedicated tensor core count. The RTX 5070 SUPER carries 6400 shading units, 200 TMUs, 80 ROPs, 50 RT cores, and 200 tensor cores. The NVIDIA part has roughly 4.2 times the shading units, 4.2 times the TMUs, 3.3 times the ROPs, and 4.2 times the RT cores compared to the Intel part.

Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level feature parity is present. The fundamental architectural split is integrated versus discrete. The B390 shares system memory with the host processor, making its bandwidth "System Dependent." The RTX 5070 SUPER has dedicated GDDR7 memory on a 192-bit bus with 672.0 GB/s of bandwidth. The B390's memory clock is listed as "System Shared" with no fixed bandwidth figure.

The RTX 5070 SUPER's transistor count is recorded at 31,100 million on a 263 mm² die, giving a transistor density of 118.3 million transistors per square millimeter. The B390's transistor count and die size are listed as unknown. The process node gap (3 nm for Intel versus 5 nm for TSMC) does not translate into a performance advantage for the integrated part in the recorded data; the discrete card's much larger shader array and dedicated memory dominate.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between the Intel Arc Pro B390 and the NVIDIA GeForce RTX 5070 SUPER. The wins counter shows zero wins for each product in paired testing. The only recorded benchmark for either product is the RTX 5070 SUPER's 3DMark Steel Nomad DX12 score of 2690 points.

That score places the RTX 5070 SUPER 1 percent ahead of the NVIDIA Quadro K1100M (2664), 1.1 percent ahead of the GeForce GT 1030 (2662), 1.1 percent ahead of the Intel Arc Pro B50 (2660), and 1.7 percent ahead of the GeForce GT 440 (2645). The margins are narrow, but the direction is consistent: the RTX 5070 SUPER beats all four nearest rivals in the database by measurable, if small, percentages.

The Intel Arc Pro B390 has no benchmark scores recorded and no nearest rivals listed. Its average benchmark score is zero, which means the database cannot substantiate any performance comparison between the two cards in synthetic workloads. The only numerical comparison available is structural: the B390 produces 7.680 TFLOPS of FP32 compute, 120.0 GTexel/s of texture fill, and 60.00 GPixel/s of pixel fill. The RTX 5070 SUPER produces 32.15 TFLOPS of FP32, 502.4 GTexel/s of texture fill, and 201.0 GPixel/s of pixel fill. In raw throughput terms, the RTX 5070 SUPER delivers about 4.2 times the FP32 compute, 4.2 times the texture rate, and 3.35 times the pixel rate of the B390.

Clock speeds tell a similar story. The B390 has a base clock of 300 MHz and a boost clock of 2500 MHz. The RTX 5070 SUPER has a base clock of 2325 MHz and a boost clock of 2512 MHz. The NVIDIA part starts far higher at base and slightly exceeds the Intel part at boost. Memory clocks differ categorically: the B390 uses system-shared memory with no fixed clock, while the RTX 5070 SUPER runs its GDDR7 at 1750 MHz (28 Gbps effective).

The Verdict

The data draws a clear line between these two products. The Intel Arc Pro B390 is an integrated graphics solution for portable devices. It uses 80 W of power, shares system memory, requires no PCIe slot, and has no recorded performance scores. Its 50th percentile standing among all GPUs comes without a single benchmark result to support it. The NVIDIA GeForce RTX 5070 SUPER is a discrete, dual-slot card with 18 GB of dedicated GDDR7, a 275 W TDP, a 16-pin power connector, and a recorded Steel Nomad score of 2690 points that beats all four of its nearest database rivals by 1 to 1.7 percent.

For any workload that requires dedicated graphics memory, high fill rates, or tensor core acceleration, the RTX 5070 SUPER is the only defensible choice in the database. Its 32.15 TFLOPS of FP32 compute is more than four times the B390's 7.680 TFLOPS. Its 672.0 GB/s of memory bandwidth is fixed and independent of host system configuration, whereas the B390's bandwidth is system dependent. Its 200 tensor cores provide a capability the B390 does not list at all.

For a portable device where the CPU package must include graphics, where no expansion slot exists, and where power draw must stay near 80 W, the B390 is the only one of the two that can physically fit. It cannot be installed in a PCIe 5.0 x16 slot because it is not a card at all. It cannot drive the same display configuration as the RTX 5070 SUPER, because its display outputs are portable-device dependent rather than fixed HDMI and DisplayPort connectors.

The release dates are close: the RTX 5070 SUPER arrived on 2025-12-31, and the B390 followed on 2026-01-26. Both are listed as active production products. Neither has a recorded launch MSRP in the database, so no price comparison is possible from the recorded data.

The practical verdict from the recorded measurements is straightforward. The RTX 5070 SUPER is the higher-performing part by every recorded metric: compute throughput, texture rate, pixel rate, memory bandwidth, shading units, RT cores, and tensor cores. The B390 wins only in power draw, physical footprint, and integration simplicity. The RTX 5070 SUPER's nearest rivals in the database are all older or lower-tier parts, and it leads each of them in the one benchmark where it was tested. The B390 has no benchmark data to challenge any of those results. A builder assembling a desktop workstation with a PCIe slot should select the RTX 5070 SUPER. A system designer integrating graphics into a Panther Lake portable platform has no choice but the B390. The two products do not compete on the same field.
