Intel Arc Graphics 128EU Mobile vs Intel Arc Pro B60 Dual Comparison

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark results between the Intel Arc Graphics 128EU Mobile and the Intel Arc Pro B60 Dual. Both products show an average benchmark score of 0 and a percentile rank of 50 among all GPUs, with no nearest rivals listed. This absence of measured data means the comparison must be built entirely from the recorded specification sheets, which reveal a substantial performance gulf.

The raw compute figures set the tone. The Arc Pro B60 Dual delivers 12.29 TFLOPS of FP32 performance, which is 2.67 times the 4.608 TFLOPS offered by the Arc Graphics 128EU Mobile. The gap widens in FP16: the Pro B60 reaches 24.58 TFLOPS (2:1) versus 9.216 TFLOPS (2:1) for the mobile part, a 2.67x advantage as well. Pixel throughput follows the same pattern, with the Pro B60 handling 192.0 GPixel/s compared to 72.00 GPixel/s on the mobile chip, a 2.67x difference. Texture rate is likewise 384.0 GTexel/s versus 144.0 GTexel/s, again a 2.67x margin.

These ratios are not coincidental. The Pro B60 packs 2560 shading units against 1024, 160 texture mapping units against 64, and 80 ROPs against 32. Every compute block scales by the same factor of 2.5, while the clock speeds close part of the gap: the Pro B60 boosts to 2400 MHz versus 2250 MHz on the mobile chip, a 6.7% higher frequency. The combination produces the uniform 2.67x performance advantage across all measured throughput categories.

Memory bandwidth tells an even more lopsided story. The Arc Pro B60 Dual uses 24 GB of GDDR6 on a 192-bit bus, delivering 456.0 GB/s of bandwidth. The Arc Graphics 128EU Mobile has system-shared memory with bandwidth described as "System Dependent", meaning its effective throughput cannot be stated as a fixed number. In any realistic configuration, dedicated GDDR6 at 456.0 GB/s will vastly outpace shared system memory, which must contend with CPU traffic and memory controller latency.

The shading unit count reinforces the compute hierarchy. With 2560 shading units, the Pro B60 offers 2.5 times the parallel execution width of the 1024-shader mobile part. The Pro B60 also includes 20 dedicated RT cores, while the mobile chip lists no RT core count at all, indicating a structural difference in ray tracing capability rather than just a numerical one.

Neither product has recorded benchmark scores in the database, so the percentile ranking of 50 for both reflects the absence of data rather than measured parity. The specification sheets, however, point decisively in one direction: the Arc Pro B60 Dual is designed for a completely different performance class, with roughly 2.7 times the raw throughput and a dedicated memory subsystem that the mobile IGP cannot match.

The Verdict

The data supports a clear separation of roles. The Intel Arc Pro B60 Dual is the dominant performer in every measurable specification: 2.67x higher FP32 throughput, 2.67x higher pixel rate, 2.67x higher texture rate, and a dedicated 456.0 GB/s memory system versus system-shared memory. It also adds 20 RT cores that the mobile chip lacks entirely.

The Arc Graphics 128EU Mobile is an integrated GPU with a 28 W TDP, designed to operate within a Meteor Lake processor. Its 4.608 TFLOPS of FP32 compute and 72.00 GPixel/s pixel rate are respectable for an IGP, but they operate in a different performance universe from the Pro B60's 12.29 TFLOPS and 192.0 GPixel/s.

The Pro B60 is a dual-slot, 400 W add-in card with a 300 mm length, 110 mm height, and 40 mm width. It requires an 800 W power supply and a PCIe 5.0 x8 slot. The mobile chip is an IGP with a Ring Bus interface, consuming 28 W and requiring no separate power connector. These are not competing products; they are complementary solutions for different physical and electrical environments.

The recorded production status for both is "Active", and both support DirectX 12 (12_1 for mobile, 12 Ultimate 12_2 for Pro), OpenGL 4.6, and Vulkan 1.4. The Pro B60 adds 12 Ultimate support and four mini-DisplayPort 2.1 outputs, while the mobile part's display outputs are "Portable Device Dependent".

The verdict from the data is unambiguous: the Arc Pro B60 Dual is the high-performance choice for workloads that demand maximum throughput and dedicated memory. The Arc Graphics 128EU Mobile is the integrated solution for portable devices where 28 W power draw and system-shared memory are the operating constraints.

Architecture Differences

The two GPUs come from different architectural generations and manufacturing processes. The Arc Graphics 128EU Mobile uses the Xe-LPG architecture on a 10 nm Intel process, fabricated by Intel itself. The Arc Pro B60 Dual uses the Xe2-HPG architecture on a 5 nm TSMC process, with 19,600 million transistors on a 272 mm² die, yielding a transistor density of 72.1M per mm².

The compute pipelines are organized differently. The mobile chip has 1024 shading units, 64 TMUs, and 32 ROPs. The Pro B60 has 2560 shading units, 160 TMUs, and 80 ROPs, giving it 2.5 times the execution resources in each category. The Pro B60 also carries 20 RT cores, a feature absent from the mobile part's specification sheet.

Memory architecture is fundamentally different. The mobile GPU relies on system-shared memory with unspecified bandwidth, while the Pro B60 has 24 GB of dedicated GDDR6 on a 192-bit interface running at 2375 MHz with 19 Gbps effective speed, producing 456.0 GB/s of bandwidth. The Pro B60 uses a PCIe 5.0 x8 bus interface, whereas the mobile chip connects via Ring Bus.

Clock behavior also differs. The mobile chip has a 300 MHz base clock that boosts to 2250 MHz, a 7.5x boost range that reflects power-constrained mobile operation. The Pro B60 runs at a 2000 MHz base clock and boosts to 2400 MHz, a much narrower 20% boost range that indicates sustained desktop-class power delivery.

The API support shows a generation gap. The Pro B60 supports DirectX 12 Ultimate (12_2), while the mobile chip supports DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4. The Pro B60 was released on 2025-09-04, nearly two years after the mobile chip's 2023-12-13 release, and the architecture names reflect that timeline: Xe2-HPG (Battlemage) versus Xe-LPG (Meteor Lake).

Where Each One Wins

The Intel Arc Pro B60 Dual wins in every raw performance metric recorded in the database. It produces 2.67x the FP32 throughput, 2.67x the FP16 throughput, 2.67x the pixel rate, and 2.67x the texture rate of the mobile chip. It offers 2.5x the shading units, 2.5x the TMUs, and 2.5x the ROPs. Its 456.0 GB/s memory bandwidth is a fixed, dedicated resource versus the mobile chip's system-dependent shared memory. The Pro B60 also adds 20 RT cores, hardware that the mobile GPU does not list at all.

The Arc Graphics 128EU Mobile wins in power efficiency and physical integration. Its 28 W TDP is 14.3x lower than the Pro B60's 400 W TDP. It requires no external power connector, no dedicated slot beyond an IGP footprint, and no separate PSU recommendation. Its Ring Bus interface means it operates within the Meteor Lake processor package, making it suitable for portable devices where the Pro B60's dual-slot, 300 mm length, 110 mm height, and 40 mm width would be physically impossible.

The Pro B60's display output configuration is fixed at 4x mini-DisplayPort 2.1, which suits professional multi-monitor setups. The mobile chip's display outputs are "Portable Device Dependent", meaning they vary with the host laptop or handheld design. The Pro B60's PCIe 5.0 x8 interface provides dedicated bandwidth for data transfer, while the mobile chip's Ring Bus shares the system fabric.

The release timeline also matters. The Pro B60 launched on 2025-09-04 with a launch MSRP of 1,199 USD. The mobile chip launched on 2023-12-13 with no MSRP listed. The Pro B60's newer architecture (Xe2-HPG) and newer process (5 nm TSMC versus 10 nm Intel) explain its higher transistor count of 19,600 million and larger die of 272 mm².

For workloads that demand maximum throughput, dedicated memory bandwidth, and ray tracing hardware, the Arc Pro B60 Dual is the only choice between the two. For battery-powered portable systems where 28 W is the entire GPU power budget and system-shared memory is the only option, the Arc Graphics 128EU Mobile is the functional solution. The data does not support any scenario where the mobile IGP outperforms the Pro B60 in compute, memory, or feature set; the Pro B60's advantages are consistent and multiplicative across every recorded specification.
