Intel Arc B580 vs NVIDIA GeForce RTX 5070 Ti Mobile Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive sweep: the NVIDIA GeForce RTX 5070 Ti Mobile wins all nine head-to-head comparisons against the Intel Arc B580. The widest margin appears in the PassMark DirectX 10 test, where NVIDIA scores 151 against Intel's 76, a 49.7% advantage. DirectX 11 follows with NVIDIA at 237 versus 128, a 46% gap. These legacy API results indicate that the NVIDIA part maintains strong performance even in older workloads where its desktop-oriented rival might be expected to fare better.

The compute-oriented tests also favor NVIDIA substantially. In Geekbench OpenCL, the RTX 5070 Ti Mobile records 143870 points, which is 35.5% ahead of the Arc B580's 92821. The Vulkan result is closer but still firmly in NVIDIA's favor: 139213 versus 109672, a 21.2% lead. GPU compute through PassMark shows NVIDIA at 10101 against 7729, a 23.5% margin. These numbers suggest that the NVIDIA mobile GPU delivers more raw compute throughput across both vendor-agnostic and vendor-specific APIs.

The 3D gaming-oriented benchmarks reinforce the pattern. PassMark G3D shows NVIDIA at 24004 versus Intel's 15748, a 34.4% lead. DirectX 12 results are less lopsided: NVIDIA scores 102 while Intel scores 76, a 25.5% gap. DirectX 9 shows NVIDIA at 259 against 183, a 29.3% advantage. The 2D test, PassMark G2D, gives NVIDIA 981 points against Intel's 709, a 27.7% margin. Every category, from legacy APIs to modern ones, from compute to rasterization, lands in favor of the RTX 5070 Ti Mobile.

The average benchmark score tells a similar story. The NVIDIA GPU averages 35435 across all recorded tests, while the Intel Arc B580 averages 23021. That difference places the two cards in different competitive tiers. The Arc B580's nearest rivals include the AMD Radeon RX 580 2048SP, which scores 23061 (0.2% ahead), and the NVIDIA GeForce RTX 3080 at 23172 (0.7% ahead). The RTX 5070 Ti Mobile sits alongside the NVIDIA Quadro GV100 at 35520 (0.2% ahead) and the AMD Radeon Pro Duo at 35860 (1.2% ahead). In other words, the Intel card competes with last-generation desktop parts, while the NVIDIA mobile GPU trades blows with professional workstation-class hardware.

Where Each One Wins

The RTX 5070 Ti Mobile wins every recorded benchmark, so the use-case split is straightforward. Its strongest relative advantages come in older DirectX APIs, where it beats the Arc B580 by nearly half in DirectX 10 and by 46% in DirectX 11. That makes it the better choice for legacy application compatibility and for games that still rely on those render paths. Modern DirectX 12 workloads show a narrower gap of 25.5%, but NVIDIA still holds the lead.

Compute performance is another clear win for NVIDIA. The Geekbench OpenCL result of 143870 is the single highest score recorded for either card in any test, and it beats the Arc B580 by 35.5%. The Vulkan score of 139213 is similarly strong. Users running GPU-accelerated compute tasks, whether through OpenCL or Vulkan, will see a meaningful performance advantage on the NVIDIA part. The PassMark GPU compute score of 10101 versus 7729 confirms this trend.

The Arc B580 does not win any category, but its closest relative performance comes in DirectX 12, where the deficit is 25.5%, and in Vulkan, where it trails by 21.2%. Its absolute scores are still respectable: 109672 in Vulkan and 15748 in PassMark G3D place it well above entry-level GPUs. The percentile data reinforces this. The Arc B580 sits at the 68th percentile among all GPUs, while the RTX 5070 Ti Mobile sits at the 80th percentile. Both are above average, but NVIDIA occupies a higher tier.

For users constrained to the Arc B580's performance envelope, the data shows it is most competitive in modern, low-level APIs like Vulkan and DirectX 12, where the architectural advantages of Xe2-HPG partially offset the raw compute deficit. In legacy APIs and in compute-heavy workloads, the gap widens considerably.

Architecture Differences

The two GPUs come from different architectural lineages. The Intel Arc B580 uses the Xe2-HPG architecture, built on the BMG-G21 chip, and belongs to the Battlemage generation under the Arc 5 series. The NVIDIA GeForce RTX 5070 Ti Mobile uses the Blackwell 2.0 architecture, built on the GB205 chip, and belongs to the GeForce 50 Mobile series.

Both chips are fabricated on a 5 nm process at TSMC, but the transistor counts differ dramatically. The NVIDIA GB205 packs 31,100 million transistors on a 263 mm² die, yielding a transistor density of 118.3 million per mm². The Intel BMG-G21 contains 19,600 million transistors on a slightly larger 272 mm² die, giving a density of 72.1 million per mm². The NVIDIA chip achieves nearly 59% more transistors per square millimeter, which contributes to its higher compute throughput despite the smaller physical die.

The shader configurations diverge sharply. The NVIDIA GPU has 5888 shading units, 184 texture mapping units, and 80 raster output units. The Intel GPU has 2560 shading units, 160 TMUs, and 80 ROPs. NVIDIA's shading unit count is more than double Intel's, while TMU counts are closer. Both cards have identical ROP counts at 80.

Ray tracing and tensor hardware also differ. The RTX 5070 Ti Mobile includes 46 ray tracing cores and 184 tensor cores. The Arc B580 has 20 ray tracing cores and no tensor core field recorded in the database. NVIDIA's ray tracing core count is more than double Intel's, and the tensor cores add dedicated AI acceleration hardware that the Intel part lacks entirely.

Clock behavior reflects the different design targets. The Intel Arc B580 runs at a constant 2670 MHz for both base and boost clocks. The NVIDIA mobile GPU runs at 847 MHz base and 1447 MHz boost. Despite running at roughly half the clock speed, the NVIDIA GPU delivers higher FP32 throughput at 17.04 TFLOPS versus 13.67 TFLOPS for Intel. This is a direct consequence of the much higher shader count. The FP16 picture is more complicated: Intel reaches 27.34 TFLOPS using a 2:1 ratio, while NVIDIA achieves 17.04 TFLOPS at a 1:1 ratio.

Specification Differences

The memory subsystems differ in type and bandwidth but share size and bus width. Both cards have 12 GB of memory on a 192-bit bus. The Intel Arc B580 uses GDDR6 at 2375 MHz with 19 Gbps effective speed, producing 456.0 GB/s of bandwidth. The NVIDIA RTX 5070 Ti Mobile uses GDDR7 at 1750 MHz with 28 Gbps effective speed, producing 672.0 GB/s. NVIDIA's memory bandwidth is 47% higher, which helps feed its larger shader array.

Power and physical design show the starkest differences. The Intel Arc B580 is a dual-slot desktop card with a 190 W TDP, a single 8-pin power connector, and a suggested 450 W PSU. Its dimensions are 272 mm in length, 115 mm in height, and 45 mm in width. The NVIDIA RTX 5070 Ti Mobile is an integrated graphics package for laptops with a 60 W TDP, no power connectors, and no recorded dimensions. The database lists its slot width as IGP, meaning it is soldered into the laptop rather than installed as a discrete card. The power disparity is enormous: the NVIDIA mobile part draws less than one-third the power of the Intel desktop card while delivering significantly higher performance.

The bus interfaces also differ. Intel uses PCIe 4.0 x8, while NVIDIA uses PCIe 5.0 x16. The NVIDIA interface offers more lanes and a newer standard, which matters for bandwidth-sensitive workloads. Display outputs are another differentiator: the Arc B580 provides 1x HDMI 2.1a and 3x DisplayPort 2.1, while the RTX 5070 Ti Mobile's outputs are listed as portable device dependent, reflecting its laptop integration.

API support is identical across both cards. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Release dates are close: the Intel GPU launched on December 12, 2024, and the NVIDIA GPU launched on February 28, 2025. The Intel card lists a launch MSRP of 249 USD; the NVIDIA card has no recorded MSRP. Production status for both is active. The Intel card's predecessor is Alchemist, while the NVIDIA card's predecessor is GeForce 40 Mobile.
