Intel Arc Graphics 4 Xe Mobile vs Intel Arc Pro B60 Dual Comparison

The Verdict

The Intel Arc Graphics 4 Xe Mobile and the Intel Arc Pro B60 Dual occupy opposite ends of the computing spectrum. The database shows the Arc Graphics 4 Xe Mobile is an integrated graphics processor (IGP) built for the Panther Lake mobile platform, sharing system memory and drawing only 25 W. The Arc Pro B60 Dual is a massive, dual-slot, 400 W discrete workstation card with 24 GB of dedicated GDDR6 memory. Benchmark results indicate these products target completely different workloads and form factors, so the selection is dictated by the system type and the performance ceiling required.

The Arc Pro B60 Dual is the clear choice for any desktop workstation requiring sustained, high-throughput compute, as it delivers 12.29 TFLOPS of FP32 performance and 456.0 GB/s of memory bandwidth. The Arc Graphics 4 Xe Mobile, with 2.355 TFLOPS and system-dependent bandwidth, is designed for portable devices where power efficiency and integration matter more than absolute throughput. The data indicates the mobile part is best suited for thin-and-light laptops, while the Pro B60 is a professional desktop accelerator. There is no scenario in the recorded data where the mobile IGP competes on raw performance with the discrete card; the decision rests on platform compatibility and power envelope constraints.

Architecture Differences

The two processors are built on fundamentally different architectures, process nodes, and manufacturing approaches. The Intel Arc Graphics 4 Xe Mobile uses the Xe3-LPG architecture, part of the Arc Graphics-M (Panther Lake) generation, fabricated on a 3 nm process at Intel. The Arc Pro B60 Dual uses the Xe2-HPG architecture from the Battlemage (Pro Series) generation, fabricated on a 5 nm process at TSMC. The process node difference is significant: the mobile part uses a more advanced 3 nm node, while the Pro card uses a 5 nm node from a different foundry.

The transistor counts tell a dramatic story. The Arc Pro B60 Dual contains 19,600 million transistors on a 272 mm² die, yielding a density of 72.1M per mm². The mobile part lists its transistor count as unknown, but its status as a 3 nm IGP indicates a much smaller implementation. The Pro B60's die size is more than double that of a typical integrated solution, and its 400 W TDP compared to the mobile part's 25 W TDP underscores the scale difference.

Core configurations differ substantially. The Arc Graphics 4 Xe Mobile has 512 shading units, 32 texture mapping units, 16 raster operation units, and 4 ray tracing cores. The Arc Pro B60 Dual has 2560 shading units, 160 TMUs, 80 ROPs, and 20 ray tracing cores. That is a 5x difference in shading units, a 5x difference in TMUs, and a 5x difference in ROPs. The Pro B60 also has 4x the ray tracing cores of the mobile part.

Memory architecture is another fundamental split. The mobile GPU uses system shared memory with system-dependent bandwidth, while the Pro B60 has 24 GB of GDDR6 on a 192-bit bus delivering 456.0 GB/s. The Pro B60's memory clock is listed at 2375 MHz with 19 Gbps effective data rate. The mobile part's memory type, bus width, and bandwidth are all listed as system-dependent, meaning performance scales with the host laptop's memory configuration.

Clock speeds also differ. The mobile part boosts to 2300 MHz from a 300 MHz base, while the Pro B60 boosts to 2400 MHz from a 2000 MHz base. Despite the higher boost clock on the Pro B60, the mobile part's much lower base clock illustrates its power-saving design intent.

Both parts share the same API support: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Pro B60 uses a PCIe 5.0 x8 interface and has four mini-DisplayPort 2.1 outputs, while the mobile part has no bus interface other than IGP and its display outputs are portable device dependent.

Where Each One Wins

The Arc Pro B60 Dual wins in every raw performance metric recorded in the database. Its pixel rate is 192.0 GPixel/s versus 36.80 GPixel/s for the mobile part, a 5.2x advantage. Texture rate is 384.0 GTexel/s versus 73.60 GTexel/s, also a 5.2x advantage. FP32 compute is 12.29 TFLOPS versus 2.355 TFLOPS, a 5.2x difference. FP16 performance follows the same pattern at 24.58 TFLOPS versus 4.710 TFLOPS. Memory bandwidth is 456.0 GB/s versus system-dependent values, which on any realistic laptop would be far below the discrete card's dedicated bandwidth.

The Arc Graphics 4 Xe Mobile wins in power efficiency and physical footprint. Its 25 W TDP is 16x lower than the Pro B60's 400 W TDP. The mobile part is an IGP with no slot width and no power connectors, while the Pro B60 is a dual-slot card measuring 300 mm in length, 110 mm in height, and 40 mm in width, requiring a 16-pin power connector and an 800 W suggested power supply. The mobile part needs no additional power supply, no PCIe slot, and no cooling solution beyond what the laptop chassis provides.

The Pro B60 is the only one of the two with a launch MSRP of 1,199 USD. The mobile part has no recorded launch MSRP, as it is an integrated component sold as part of a Panther Lake laptop platform.

Head-to-Head Benchmarks

The database lists no direct head-to-head benchmark entries between these two products, and neither has recorded average benchmark scores. However, the theoretical peak rates in the specification data provide a complete basis for comparison, since both parts list the same metric types.

The largest single-metric advantage for the Arc Pro B60 Dual is in memory bandwidth. The discrete card provides 456.0 GB/s of dedicated GDDR6 bandwidth, while the mobile part's bandwidth is listed as system dependent. On any laptop using shared system memory, the bandwidth would be constrained by the system memory channels and would not approach the dedicated 456.0 GB/s figure. This difference matters most for large dataset workloads, where the Pro B60 can sustain data movement far beyond what an IGP can achieve.

In pixel throughput, the Pro B60's 192.0 GPixel/s versus the mobile part's 36.80 GPixel/s represents a 5.22x advantage. This metric affects fill-rate-bound scenarios such as high-resolution rendering with heavy fragment shading. The texture rate comparison shows the same ratio: 384.0 GTexel/s versus 73.60 GTexel/s, which benefits the Pro B60 in texture-heavy scenes.

Compute throughput follows the identical pattern. FP32 performance of 12.29 TFLOPS versus 2.355 TFLOPS gives the Pro B60 a 5.22x lead. FP16 performance of 24.58 TFLOPS versus 4.710 TFLOPS maintains the same ratio. These figures indicate the Pro B60 can process roughly five times as many floating-point operations per second in both single and half precision, which directly translates to faster simulation, rendering, and compute workloads.

The ray tracing hardware difference is equally pronounced. The Pro B60 has 20 ray tracing cores versus 4 on the mobile part, a 5x difference. In ray-traced workloads, the Pro B60 has substantially more dedicated hardware to handle intersection and traversal calculations.

Clock speeds provide a nuanced comparison. The Pro B60 has a 2400 MHz boost clock versus 2300 MHz on the mobile part, a modest 4.3% advantage. However, the base clocks differ far more dramatically: 2000 MHz versus 300 MHz. This means the Pro B60 maintains near-peak performance under sustained load, while the mobile part can drop to 300 MHz when power or thermal limits force it down. The mobile part's 25 W TDP makes sustained high-clock operation unlikely under heavy load.

The ROP and TMU counts reinforce the same conclusion. The Pro B60's 80 ROPs and 160 TMUs compare to 16 ROPs and 32 TMUs on the mobile part, again a 5x difference. These fixed-function units scale directly with the shading engine count, so the Pro B60's advantage is consistent across all rendering stages.

The Pro B60's transistor budget of 19,600 million versus an unknown count for the mobile part, combined with the 272 mm² die size, indicates the discrete card dedicates far more silicon to compute resources. The mobile part's 3 nm process allows it to pack its smaller configuration into an integrated footprint, but the total resource count remains far lower.

The release dates place the mobile part later, with a 2026-01-26 date, while the Pro B60 was released on 2025-09-04. Both are listed as active production parts. The Pro B60 is the only one with a launch MSRP, recorded at 1,199 USD.

In professional workstation contexts, the Pro B60's 24 GB of GDDR6 memory and 456.0 GB/s bandwidth support larger datasets than the shared-memory mobile part can access. The mobile IGP is limited by the host system's memory allocation and bandwidth, which is shared with the CPU and other system components. The Pro B60's dedicated memory eliminates this contention entirely.

The physical comparison is stark. The Pro B60 requires a dual-slot chassis, a 16-pin power connector, an 800 W suggested power supply, and a PCIe 5.0 x8 slot. The mobile part requires none of these, operating entirely within the laptop's existing power and cooling infrastructure. The Pro B60's 400 W TDP alone exceeds the total power budget of many portable devices, making the two products mutually exclusive in practical deployment.
