Intel Arc B580 vs Intel Graphics 24EU Mobile Comparison

Head-to-Head Benchmarks

The Intel Arc B580 and Intel Graphics 24EU Mobile occupy entirely different performance strata, and the recorded data reflects a gap that is not merely incremental but structural. The Arc B580 posts an average benchmark score of 23021 across ten tests, while the 24EU Mobile has no recorded benchmark entries in the database, yielding an average score of zero. This absence of data for the integrated part means every head-to-head comparison must rely on the Arc B580's absolute scores and its positioning against discrete rivals.

In 3DMark Steel Nomad DX12, the Arc B580 records 3068 points. That score places it within 0.2% of the AMD Radeon RX 580 2048SP (23061 average) and 0.6% ahead of the NVIDIA GeForce RTX 2080 (22895 average). The Geekbench OpenCL result of 92821 and Vulkan result of 109672 confirm strong compute throughput. Passmark G3D shows 15748, while GPU compute reaches 7729. DirectX 11 yields 128, DirectX 9 yields 183, and both DirectX 10 and DirectX 12 return 76. The G2D score is 709.

The 24EU Mobile, by contrast, has no scores to compare. Its percentile rank of 50 versus the Arc B580's 68 indicates the database places the integrated chip at the median of all GPUs, though without benchmark confirmation this rank appears derived from its specification class rather than measured performance. The Arc B580's 68th percentile means it outperforms roughly two-thirds of all recorded GPUs, a position supported by its proximity to the RTX 3080 (23172 average, Arc B580 trails by 0.7%) and the NVIDIA P106-100 (23249 average, Arc B580 trails by 1%).

The largest measurable deltas come from the Arc B580's compute-heavy workloads. Its FP32 throughput of 13.67 TFLOPS and texture rate of 427.2 GTexel/s are orders of magnitude above the 24EU Mobile's 384.0 GFLOPS and 12.00 GTexel/s. Pixel rate tells the same story: 213.6 GPixel/s versus 4.000 GPixel/s. The Arc B580 delivers 456.0 GB/s of memory bandwidth from 12 GB of GDDR6 on a 192-bit bus, while the 24EU Mobile relies on system-shared memory with bandwidth described only as system dependent.

Where Each One Wins

The Arc B580 wins every measurable category where data exists. Its 2560 shading units, 160 TMUs, and 80 ROPs dwarf the 24EU Mobile's 192 shading units, 12 TMUs, and 4 ROPs. The Arc B580 also includes 20 ray tracing cores, a feature entirely absent from the 24EU Mobile. For gaming workloads, the Arc B580's DirectX 12 Ultimate (12_2) support enables features the 24EU Mobile's DirectX 12 (12_1) cannot access. The discrete card's 190 W TDP and dual-slot design indicate sustained high-load capability, whereas the 24EU Mobile's 6 W TDP and IGP form factor target power-constrained mobile environments.

The 24EU Mobile wins only in portability and integration. As an IGP on a Ring Bus interface, it requires no power connectors and no suggested PSU. Its display outputs are listed as portable device dependent, meaning it adapts to whatever panel the host device provides. The Arc B580, in contrast, needs a 450 W suggested PSU, a single 8-pin connector, and occupies 272 mm of length with a dual-slot width. For systems where physical space and power budgets are the primary constraints, the 24EU Mobile is the only viable option. For any performance-oriented task, the Arc B580 wins outright.

The database shows no wins for the 24EU Mobile in any benchmark, and its empty benchmark array confirms that no measured performance data exists. The Arc B580's nearest rivals are all discrete desktop GPUs from AMD and NVIDIA, which indicates the database classifies it as a high-end part. The 24EU Mobile's nearest rivals list is empty, reinforcing that it has no comparable peers in the recorded data.

Architecture Differences

The Arc B580 uses the Xe2-HPG architecture on a 5 nm TSMC process, built around the BMG-G21 chip. It belongs to the Battlemage generation within the Arc 5 series. The chip contains 19,600 million transistors across a 272 mm² die, yielding a transistor density of 72.1M per mm². The 24EU Mobile uses the older Xe-LP architecture on Intel's 10 nm process, built around the Twin Lake chip. It belongs to the HD Graphics-T generation. Transistor count and die size are listed as unknown, with no density figure.

The Arc B580's memory subsystem is discrete: 12 GB of GDDR6 at 2375 MHz with 19 Gbps effective speed, a 192-bit bus, and 456.0 GB/s bandwidth. The 24EU Mobile shares system memory with no dedicated VRAM, no fixed bus width, and bandwidth that varies with the host platform. This fundamental difference explains the performance gap in memory-intensive workloads.

Clock behavior differs substantially. The Arc B580 runs at a constant 2670 MHz for both base and boost, indicating a fixed operating point. The 24EU Mobile has a 300 MHz base and 1000 MHz boost, a wide range that suggests aggressive power management. The Arc B580's FP32 throughput of 13.67 TFLOPS and FP16 of 27.34 TFLOPS (2:1) compare with the 24EU Mobile's 384.0 GFLOPS and 768.0 GFLOPS (2:1), a factor of roughly 35 in both cases.

API support shows a partial convergence. Both parts support OpenGL 4.6 and Vulkan 1.4. The Arc B580 reaches DirectX 12 Ultimate (12_2), while the 24EU Mobile stops at DirectX 12 (12_1). The Arc B580's display outputs include 1x HDMI 2.1a and 3x DisplayPort 2.1, whereas the 24EU Mobile's outputs are portable device dependent, meaning they are dictated by the host laptop or mini PC. The Arc B580 uses PCIe 4.0 x8, while the 24EU Mobile uses a Ring Bus interface, reflecting its integrated nature.

The Verdict

The data supports only one conclusion for performance-sensitive buyers: the Intel Arc B580 is the clear choice. Its 68th percentile rank, average score of 23021, and proximity to the RTX 3080 and RX 580 2048SP in the database place it firmly in discrete desktop class. The 24EU Mobile's 50th percentile rank with no benchmark data makes it suitable only for basic display output and light compute tasks where power consumption of 6 W is paramount.

The Arc B580's launch MSRP is 249 USD, and it was released on 2024-12-12. The 24EU Mobile was released on 2024-12-31 with no MSRP listed, as it is an integrated part sold as part of a larger system. For users building a desktop with a PCIe slot, the Arc B580 delivers measured performance across all recorded tests. For users requiring an IGP with 6 W power draw and no additional hardware, the 24EU Mobile is the only option that fits the form factor.

The Arc B580's ray tracing cores and DirectX 12 Ultimate support give it a feature set that the 24EU Mobile lacks entirely. The 24EU Mobile has no RT cores and only DirectX 12 (12_1). The Arc B580's 12 GB VRAM provides headroom for large textures and datasets, while the 24EU Mobile's shared memory is system dependent. The verdict from the database is unambiguous: the Arc B580 for any workload that benefits from GPU acceleration, the 24EU Mobile only for minimum-power integrated scenarios.
