AMD Radeon 840M vs Intel Arc Pro B60 Dual Comparison

Head-to-Head Benchmarks

The recorded data for this comparison contains no direct head-to-head benchmark results. The database lists zero benchmark scores for the AMD Radeon 840M and zero for the Intel Arc Pro B60 Dual, and the wins tally stands at zero for each side. This absence of measured performance data means that conclusions must be drawn exclusively from the architectural specifications and the percentile rankings.

Both products sit at the 50th percentile against all GPUs in the database, a parity that is unusual given the massive gap in their physical and electrical characteristics. The Intel Arc Pro B60 Dual is a discrete, dual-slot card with a 400 W TDP, while the AMD Radeon 840M is an integrated graphics processor (IGP) with a 15 W TDP. The percentile score suggests that, in the database's overall ranking system, these two are treated as equivalent mid-pack performers, despite the stark differences in their design goals.

Without benchmark numbers, the most telling quantitative comparison comes from raw throughput figures. The Intel card delivers 12.29 TFLOPS of FP32 compute, which is roughly 8.3 times the 1,484.8 GFLOPS (1.48 TFLOPS) of the AMD IGP. In pixel throughput, the Intel card achieves 192.0 GPixel/s against 23.20 GPixel/s for the AMD part, an 8.3-fold advantage. Texture rate follows the same pattern: 384.0 GTexel/s versus 46.40 GTexel/s. These ratios dwarf the percentile parity and indicate that the database's ranking system may weight factors beyond raw speed, such as power efficiency, availability, or market segment.

The FP16 comparison is notable for the different ratio approaches. The AMD Radeon 840M lists FP16 at 1,484.8 GFLOPS with a 1:1 ratio to FP32, meaning it offers no half-precision acceleration. The Intel Arc Pro B60 Dual lists FP16 at 24.58 TFLOPS with a 2:1 ratio, doubling its FP32 rate. This gives the Intel card a 16.5-fold advantage in FP16 workloads, a larger margin than the FP32 gap. For compute tasks that leverage half-precision, such as certain AI inference or graphics post-processing, the Intel architecture holds a clear specification edge.

Architecture Differences

The two GPUs come from entirely different design philosophies and process technologies. The AMD Radeon 840M uses the RDNA 3.5 architecture on a 4 nm TSMC node, a refinement of the RDNA line aimed at energy-efficient mobile graphics. It is part of the Navi III IGP generation for Strix Point Mobile and uses the Krackan Point chip. The Intel Arc Pro B60 Dual uses Xe2-HPG architecture on a 5 nm TSMC node, representing the Battlemage generation for the Pro Series. The process node difference, 4 nm versus 5 nm, favors AMD in theoretical density, but the Intel chip compensates with a much larger physical implementation.

The Intel part is a substantial die: 19,600 million transistors on a 272 mm² die, with a transistor density of 72.1M per mm². The AMD IGP's transistor count and die size are listed as unknown in the database, preventing a direct density comparison. What is clear is the scale difference: the Intel GPU uses 2,560 shading units, 160 texture mapping units, and 80 render output units. The AMD IGP uses 256 shading units, 16 TMUs, and 8 ROPs. That is a 10:1 ratio in shading units and TMUs, and a 10:1 ratio in ROPs as well.

Ray tracing hardware also differs significantly. The AMD part includes 4 RT cores, while the Intel card includes 20 RT cores, a 5:1 advantage. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API feature levels are identical. Neither lists tensor cores, so AI acceleration is not quantified separately in the database.

Clock behavior reveals a different strategy. The AMD Radeon 840M has a base clock of 400 MHz and a boost clock of 2900 MHz, a 7.25x boost range that is typical for power-constrained mobile parts. The Intel Arc Pro B60 Dual has a base clock of 2000 MHz and a boost of 2400 MHz, a modest 1.2x range, reflecting a high-idle, high-sustained design for a discrete card with dedicated cooling. Memory clocks diverge even more: AMD uses system-shared memory with a system-dependent bandwidth, while Intel uses 2375 MHz (19 Gbps effective) GDDR6.

The memory subsystem is where the Intel card's dominance becomes absolute. It offers 24 GB of GDDR6 on a 192-bit bus with 456.0 GB/s bandwidth. The AMD IGP shares system memory with no dedicated VRAM, no fixed bus width, and bandwidth that depends entirely on the host platform's DRAM configuration. For any workload that saturates memory bandwidth, the Intel card has a hard architectural advantage that no driver or software optimization can overcome.

The Verdict

The database shows a clear structural verdict: the Intel Arc Pro B60 Dual is a professional-grade discrete GPU with massive advantages in every measured compute and memory metric. Its 12.29 TFLOPS FP32, 24 GB GDDR6, and 456.0 GB/s bandwidth place it in a different performance class from the AMD Radeon 840M, a 15 W integrated solution with system-shared memory. The 400 W TDP and dual-slot cooler confirm that Intel's part is designed for sustained, high-throughput workloads in a desktop or workstation chassis.

The AMD Radeon 840M, by contrast, is an IGP for mobile platforms. Its 4 nm process and 15 W TDP indicate a design goal of delivering modest graphics capability within a tight power envelope. The 2900 MHz boost clock on a 400 MHz base suggests aggressive power management, ramping up only when thermal and power headroom allow. Its system-shared memory means performance scales with the host CPU's memory subsystem, a variable the database cannot quantify.

The percentile parity (50th for both) is the only metric where they match, but this likely reflects the database's normalization across all GPUs, where an IGP and a workstation card can occupy the same rank for different reasons. The release dates differ by about six months, with the AMD part launching on February 28, 2025, and the Intel part on September 4, 2025. The Intel card carries a launch MSRP of 1,199 USD, while the AMD IGP has no standalone price because it is integrated into a processor.

Where Each One Wins

The Intel Arc Pro B60 Dual wins in every scenario that demands raw graphics throughput, high-resolution texture work, or large memory footprints. Its 10:1 advantages in shading units, TMUs, and ROPs, plus its 20 RT cores, make it suited for rendering, simulation, and content creation. The 24 GB GDDR6 frame buffer supports large datasets, and the 456.0 GB/s bandwidth sustains heavy memory traffic. The 4x mini-DisplayPort 2.1 outputs and PCIe 5.0 x8 interface position it for multi-display professional setups.

The AMD Radeon 840M wins in scenarios where power draw and physical footprint are the primary constraints. Its 15 W TDP means it can operate without additional power connectors, inside a laptop or compact mobile device. The 4 nm process node and 1:1 FP16 ratio indicate a design tuned for efficiency rather than peak throughput. The 2900 MHz boost clock shows it can reach high frequencies when needed, but the system-shared memory and 8 ROPs limit its ceiling for pixel-heavy tasks.

For mobile productivity, light gaming, or basic 3D acceleration in a thin-and-light chassis, the AMD IGP is the only viable option of the two, since a dual-slot, 400 W card cannot physically fit or be powered in such a system. For any stationary workstation, the Intel Arc Pro B60 Dual wins outright on every specification that matters for performance. The data does not support a middle ground: the two products occupy opposite ends of the GPU spectrum, and the choice is dictated entirely by the target platform.
