Intel Arc Graphics 32EU vs Intel Arc Pro B65 Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark results between the Intel Arc Graphics 32EU and the Intel Arc Pro B65. The database lists a single 3DMark Steel Nomad DX12 score of 733 for the Arc Graphics 32EU, placing it at the 3rd percentile among all GPUs. The Arc Pro B65 has no benchmark entries in the database, with an average score of zero and a 50th percentile standing. This makes a direct numeric comparison impossible. What can be analyzed is the relative positioning of each part based on the data that does exist.

The Arc Graphics 32EU, despite its low percentile rank, shows a peculiar clustering among its nearest rivals. It is exactly matched by the Intel Arc Graphics 24EU and the Intel Arc Graphics 64EU, both scoring 733 with a delta of 0. This indicates that within this specific benchmark, the 32EU configuration delivers identical performance to both the smaller 24EU and the larger 64EU variants. The data suggests that the Steel Nomad workload may not be sensitive to the shading unit count differences between these three Intel parts, or that the 32EU part is operating at a performance ceiling imposed by another factor such as memory bandwidth, which is listed as System Dependent.

The Arc Graphics 32EU edges out the AMD Radeon HD 6470M by 1.4 percent, scoring 733 against 723. It trails the NVIDIA GeForce GT 415M by 2.4 percent, with the NVIDIA part scoring 751. These deltas are small, placing all four GPUs within a narrow performance band of roughly 28 points. The 3rd percentile ranking reinforces the position of the Arc Graphics 32EU as a low-end integrated solution. The Arc Pro B65 has no comparable scores, so its relative performance against these same rivals cannot be derived from the database.

The Arc Pro B65 instead offers a different kind of evidence: its 50th percentile ranking places it at the median of all GPUs in the database. With no benchmark scores recorded, this percentile is likely derived from its specifications rather than measured results. The data presents a clear separation: one part has measured scores and a low percentile, the other has no scores and a median percentile. Any head-to-head comparison must therefore rely on the architecture, memory, and compute specifications listed for each.

Where Each One Wins

The Arc Graphics 32EU wins in the domain of integration and power efficiency. It is an IGP with a 65 W TDP, uses a Ring Bus interface, and relies on System Shared memory. Its display outputs are Motherboard Dependent, meaning it fits into systems without a discrete graphics card. The benchmark score of 733, while modest, is a measured result that confirms it can run the Steel Nomad workload. It also matches the performance of the 24EU and 64EU variants in that test, which is a notable outcome for a part with only 256 shading units.

The Arc Pro B65 wins in every raw compute and memory category recorded. It delivers 12.29 TFLOPS of FP32 performance versus 998.4 GFLOPS for the Arc Graphics 32EU, a difference of roughly 12.3 times. Its texture rate is 384.0 GTexel/s against 31.20 GTexel/s, and its pixel rate is 192.0 GPixel/s against 15.60 GPixel/s. The B65 has 32 GB of GDDR6 memory on a 256 bit bus with 608.0 GB/s of bandwidth, while the 32EU uses System Shared memory with System Dependent bandwidth. The B65 also includes 20 ray tracing cores, a feature entirely absent from the 32EU specification.

The use-case split follows these numbers. The Arc Graphics 32EU suits motherboards and processors that integrate graphics, offering a measured baseline of performance for everyday display output and light 3D workloads. The Arc Pro B65 targets professional and compute-heavy scenarios where 32 GB of dedicated GDDR6, 2560 shading units, and ray tracing support matter. The B65 is a Dual-slot card requiring a 550 W power supply and a single 8-pin connector, while the 32EU needs no additional power connectors and draws 65 W. The data does not record any workload where the 32EU outperforms the B65, but the absence of B65 benchmark scores prevents a definitive statement on real-world deltas.

Architecture Differences

The two GPUs come from different architectures, nodes, and process generations. The Arc Graphics 32EU is built on the Xe-LPG architecture, part of the Arc Graphics-M (Arrow Lake) generation, using a 3 nm process at TSMC. It contains 17,800 million transistors on a 243 mm² die, yielding a transistor density of 73.3M per mm². The chip is designated Arrow Lake-S. Its base clock is 300 MHz with a boost of 1950 MHz. The memory subsystem is System Shared, meaning capacity, type, and bus width all depend on the host system.

The Arc Pro B65 uses the Xe2-HPG architecture, part of the Battlemage (Pro Series) generation, built on a 5 nm process at TSMC. It carries 19,600 million transistors on a 272 mm² die, with a transistor density of 72.1M per mm². The chip is BMG-G21. Clocks are locked at 2400 MHz for both base and boost. Memory is 32 GB of GDDR6 running at 2375 MHz, or 19 Gbps effective, on a 256 bit bus delivering 608.0 GB/s.

The compute resources differ sharply. The 32EU has 256 shading units, 16 TMUs, and 8 ROPs. The B65 has 2560 shading units, 160 TMUs, and 80 ROPs. The B65 adds 20 ray tracing cores; the 32EU has none listed. The B65 connects via PCIe 5.0 x16, while the 32EU uses a Ring Bus. The B65 provides 4x DisplayPort 2.1 outputs, while the 32EU depends on the motherboard for display connectivity. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical. The transistor density is nearly the same, 73.3M vs 72.1M per mm², which is expected given the different process nodes and die sizes.

Power and physical specifications also diverge. The 32EU is an IGP with a 65 W TDP and no power connectors. The B65 is a Dual-slot card with a 200 W TDP, a single 8-pin power connector, and a suggested power supply of 550 W. Release dates place the 32EU on 2024-10-23 and the B65 on 2026-03-31. The 32EU lists HD Graphics-M as its predecessor; the B65 has no predecessor recorded.

The Verdict

The data separates these two GPUs into distinct roles. The Intel Arc Graphics 32EU is an integrated graphics solution for Arrow Lake-S systems. Its measured Steel Nomad score of 733, its 3rd percentile ranking, and its 65 W TDP place it firmly in the entry-level integrated segment. It matches the 24EU and 64EU variants in the recorded benchmark, which indicates that its 256 shading units are sufficient for that specific workload, but its System Shared memory and Motherboard Dependent outputs restrict it to general desktop use.

The Intel Arc Pro B65 is a discrete, professional-grade card. Its 50th percentile ranking, 2560 shading units, 20 ray tracing cores, 32 GB of GDDR6, and 608.0 GB/s of bandwidth put it in a different performance class. The 12.29 TFLOPS of FP32 compute is over 12 times the 998.4 GFLOPS of the 32EU. Its 200 W TDP, Dual-slot design, and 550 W suggested power supply confirm it is built for dedicated workstations, not integrated systems.

For users with an Arrow Lake-S platform, the 32EU provides a measured, if modest, graphics baseline without additional hardware. For users needing dedicated memory, ray tracing, and high compute throughput, the B65 is the only one of the two with the specifications to deliver it. The absence of B65 benchmark scores means the database cannot quantify the exact performance gap, but the specification differences are substantial enough to define the choice. The 32EU is for integrated convenience; the B65 is for dedicated compute.
