Intel Arc Graphics 24EU vs Intel Arc Pro B65 Comparison

Intel Arc Graphics 24EU and Intel Arc Pro B65 occupy separate corners of Intel’s graphics lineup, one designed for integration into desktop processors and the other for professional discrete workloads. The recorded data shows a substantial capability gap between them, driven by differences in architecture, memory configuration, and execution resources. This analysis compares the two strictly from database measurements.

Head-to-Head Benchmarks

The database contains a single benchmark entry for the Intel Arc Graphics 24EU: a 3DMark Steel Nomad DX12 score of 733. The Intel Arc Pro B65 has no recorded benchmark scores in the database, and no head-to-head benchmark entries exist for the pair. Consequently, direct score comparisons are limited to the 24EU’s position against its nearest rivals.

The 24EU’s 733 score places it at the 3rd percentile of all GPUs, indicating performance at the very low end of the database spectrum. Its nearest rival, the Intel Arc Graphics 32EU, also scores 733, showing a 0% difference. The Intel Arc Graphics 64EU matches that score as well, also at 0% delta. This suggests that within the Arc Graphics integrated family, increasing execution units from 24 to 64 does not translate into a measurable improvement in this particular DirectX 12 workload, at least according to the recorded data.

Against older discrete parts, the 24EU sits narrowly ahead of the AMD Radeon HD 6470M, which scores 723, a 1.4% advantage for the Intel part. The NVIDIA GeForce GT 415M scores 751, placing it 2.4% ahead of the 24EU. These deltas are small, keeping the 24EU in a tight performance cluster with these legacy mobile GPUs. The Arc Pro B65, with no benchmark score recorded, cannot be positioned against the 24EU or any other part using measured results. Its 50th percentile ranking across all GPUs, however, indicates a mid-pack standing, a stark contrast to the 24EU’s 3rd percentile placement.

Where Each One Wins

Based on the available data, the Intel Arc Graphics 24EU wins in scenarios where an integrated GPU with minimal power draw is sufficient. Its 65 W TDP, IGP slot width, and system-shared memory make it suitable for basic desktop tasks and light 2D acceleration. It matches the performance of the Arc Graphics 32EU and 64EU in the Steel Nomad test, meaning users with standard office workloads or media playback would not see a difference between these integrated options. The 24EU also edges out the AMD Radeon HD 6470M by 1.4%, confirming it can handle the same legacy workload class.

The Intel Arc Pro B65 wins in every compute-heavy and professional scenario by virtue of its specifications, even without a benchmark score. It delivers 2560 shading units against the 24EU’s 192, a 13.3x difference in raw shader count. Its pixel rate of 192.0 GPixel/s is 16x higher than the 24EU’s 12.00 GPixel/s, and its texture rate of 384.0 GTexel/s is 16x higher than 24.00 GTexel/s. FP32 throughput measures 12.29 TFLOPS versus 768.0 GFLOPS, a 16x advantage. The Pro B65 also has 20 ray tracing cores, which the 24EU lacks entirely. For 3D rendering, video encoding, CAD, or any workload that uses ray tracing, the Pro B65 is the only viable option between the two.

Memory bandwidth separates them further. The Pro B65 uses 32 GB of GDDR6 on a 256-bit bus, delivering 608.0 GB/s. The 24EU relies on system shared memory with bandwidth listed as system dependent. The Pro B65’s dedicated memory avoids contention with the CPU and provides predictable bandwidth for large datasets. The 24EU’s performance in memory-sensitive tasks will vary with the host system’s RAM configuration, a factor the database cannot quantify.

Architecture Differences

The two GPUs use different architectures and process nodes. The Intel Arc Graphics 24EU is built on Xe-LPG architecture, fabricated by TSMC on a 3 nm process. The chip is part of the Arrow Lake-S processor family, with a die size of 243 mm² and 17,800 million transistors. Transistor density measures 73.3M per mm². The Intel Arc Pro B65 uses Xe2-HPG architecture, fabricated by TSMC on a 5 nm process. Its chip, BMG-G21, has a die size of 272 mm² and 19,600 million transistors, with a density of 72.1M per mm². The newer 3 nm node gives the 24EU a slightly higher transistor density despite having fewer total transistors.

Execution resource counts diverge sharply. The 24EU has 192 shading units, 12 texture mapping units, and 6 render output units. The Pro B65 has 2560 shading units, 160 TMUs, and 80 ROPs. The Pro B65 also includes 20 ray tracing cores; the 24EU has none. Neither part lists tensor cores in the database. Clock speeds differ as well: the 24EU runs at a 300 MHz base and 2000 MHz boost, while the Pro B65 runs at a flat 2400 MHz for both base and boost. The Pro B65’s higher clock rate, combined with its much larger shader count, accounts for its massive throughput advantage.

Memory architecture reflects their different roles. The 24EU uses system shared memory with no dedicated VRAM, a typical configuration for integrated graphics. The Pro B65 has 32 GB of GDDR6 running at 2375 MHz (19 Gbps effective) on a 256-bit bus. The Pro B65’s bus interface is PCIe 5.0 x16, while the 24EU uses a Ring Bus connection, consistent with its integrated nature. Display outputs also differ: the 24EU’s outputs are motherboard dependent, while the Pro B65 provides 4x DisplayPort 2.1.

Power and physical specs reinforce the divide. The 24EU has a 65 W TDP and is listed as IGP slot width with no power connectors. The Pro B65 has a 200 W TDP, is dual-slot, requires a single 8-pin power connector, and suggests a 550 W power supply. The Pro B65’s release date is later in the database, with the 24EU appearing first.

The Verdict

The data draws a clear line. The Intel Arc Graphics 24EU is an integrated solution for systems where a discrete GPU is absent or unnecessary. Its 3rd percentile ranking and 733 Steel Nomad score place it at the entry level, competitive only with legacy mobile parts like the Radeon HD 6470M and GeForce GT 415M. It matches the 32EU and 64EU variants in the recorded test, so users with basic needs will find it sufficient. Its 65 W TDP and system shared memory make it a low-power option for office machines or media centers.

The Intel Arc Pro B65 is a professional discrete GPU aimed at workloads that demand throughput. Its 50th percentile standing, while not a top-tier rank, indicates mainstream capability. The 16x advantage in FP32, pixel rate, and texture rate over the 24EU, combined with 20 ray tracing cores and 608.0 GB/s of dedicated bandwidth, positions it for 3D rendering, compute tasks, and high-resolution display output. Its 200 W TDP and 550 W suggested PSU reflect the power needed for that performance.

The choice depends on the task. For integrated graphics with minimal power draw, the 24EU delivers baseline performance. For any workload that stresses the GPU, the Pro B65 is the only one of the two that can handle it, and its specifications confirm that role. The absence of benchmark scores for the Pro B65 means its exact performance relative to other discrete GPUs remains unmeasured in the database, but its resource counts and memory subsystem leave no doubt about its advantage over the 24EU.
