AMD Radeon 680M vs Intel Arc Pro B65 Comparison

Head-to-Head Benchmarks

The benchmark database contains no direct head-to-head test results between the AMD Radeon 680M and the Intel Arc Pro B65. The headToHeadBenchmarks field is empty, and neither product has a recorded win in direct comparison. This absence of matched testing means any performance comparison must rely on the individual benchmark scores each product has generated in the database.

For the AMD Radeon 680M, the recorded measurements show three benchmark results. In 3DMark Steel Nomad DX12, the 680M scores 378 points. Its Geekbench OpenCL result is 23,468 points, while the Vulkan test returns 21,965 points. The average benchmark score for the 680M across all recorded tests is 15,270 points. That average places the 680M in the 57th percentile of all GPUs in the database.

The Intel Arc Pro B65 has no benchmark scores recorded in the database. The benchmarks array is empty, and the average benchmark score is listed as 0. The percentile ranking sits at 50, which represents the default midpoint rather than a measured performance position. With no recorded data points, the Arc Pro B65 cannot be positioned against the 680M through direct measurement.

The nearest rivals for the 680M provide context for its standing. The NVIDIA GeForce GTX 580 averages 15,283 points, which is 0.1% higher than the 680M's average. The NVIDIA GeForce RTX 2060 averages 15,290 points, also 0.1% higher. The NVIDIA GeForce RTX 3050 OEM averages 15,199 points, which is 0.5% lower than the 680M. The AMD Radeon RX 7600 averages 15,171 points, 0.7% lower. These deltas indicate the 680M sits in a tight cluster with those discrete GPUs, essentially matching their aggregate performance despite being an integrated graphics processor.

For the Arc Pro B65, there are no nearest rivals listed in the database. Without benchmark scores or rival comparisons, the data provides no basis for a quantitative performance assessment. The only measurable facts are its hardware specifications, which can be analyzed for architectural capability but not for tested performance.

Architecture Differences

The two processors represent fundamentally different design approaches. The AMD Radeon 680M uses the Rembrandt+ chip built on RDNA 2.0 architecture, belonging to the Navi II IGP generation for Rembrandt Mobile. It is manufactured on a 6 nm process at TSMC. The Intel Arc Pro B65 uses the BMG-G21 chip built on Xe2-HPG architecture, belonging to the Battlemage generation for the Pro Series. It is manufactured on a 5 nm process, also at TSMC.

Transistor counts differ substantially. The 680M contains 13,100 million transistors on a 208 mm² die, yielding a transistor density of 63.0 million per square millimeter. The Arc Pro B65 contains 19,600 million transistors on a 272 mm² die, yielding a density of 72.1 million per square millimeter. The Intel part packs roughly 50% more transistors onto a die that is about 31% larger, with a higher density figure.

Clock behavior shows a notable divergence. The 680M runs at a 2000 MHz base clock and boosts to 2200 MHz. The Arc Pro B65 operates at a fixed 2400 MHz for both base and boost, meaning it does not rely on dynamic boost headroom. The memory clock for the Arc Pro B65 is listed as 2375 MHz with 19 Gbps effective data rate.

Compute resources scale in favor of the Intel part. The 680M has 768 shading units, 48 texture mapping units, and 32 raster operation pipelines. It also includes 12 ray tracing cores. The Arc Pro B65 has 2,560 shading units, 160 TMUs, and 80 ROPs, with 20 ray tracing cores. The Intel GPU offers more than three times the shading units and TMUs, and two and a half times the ROPs.

The memory subsystem is the most dramatic difference. The 680M uses system shared memory with no dedicated VRAM, making its bandwidth system dependent. The Arc Pro B65 has 32 GB of GDDR6 memory on a 256-bit bus, delivering 608.0 GB/s of bandwidth. That dedicated memory bandwidth is a fundamental architectural advantage for workloads that stress memory throughput.

Pixel and texture rates reflect the compute advantage. The 680M delivers 70.40 GPixel/s and 105.6 GTexel/s. The Arc Pro B65 delivers 192.0 GPixel/s and 384.0 GTexel/s. Floating point performance follows the same pattern: the 680M reaches 3.379 TFLOPS FP32 and 6.758 TFLOPS FP16, while the Arc Pro B65 reaches 12.29 TFLOPS FP32 and 24.58 TFLOPS FP16.

Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The power envelope differs widely: the 680M is rated at 50 W TDP and is an IGP with no power connectors, while the Arc Pro B65 is rated at 200 W TDP, occupies a dual-slot form factor, and requires a single 8-pin power connector with a suggested 550 W power supply. The bus interface also differs: PCIe 4.0 x8 for the 680M versus PCIe 5.0 x16 for the Arc Pro B65. Display outputs for the 680M are portable device dependent, while the Arc Pro B65 provides four DisplayPort 2.1 outputs.

The Verdict

The recorded data shows two products at opposite ends of the GPU spectrum. The AMD Radeon 680M is an integrated graphics processor with a 50 W TDP, system shared memory, and a 57th percentile ranking based on an average benchmark score of 15,270 points. Its nearest rivals include the GeForce GTX 580, RTX 2060, RTX 3050 OEM, and Radeon RX 7600, all within 0.7% of its average score. The 680M delivers performance comparable to those discrete GPUs while drawing a fraction of their power and fitting into an IGP form factor.

The Intel Arc Pro B65 has no recorded benchmark scores, no rivals, and an average score of 0. The database cannot confirm its performance position. What the data does show is a hardware specification that is dramatically more capable on paper: 2,560 shading units, 32 GB of GDDR6, 608.0 GB/s bandwidth, 12.29 TFLOPS FP32, and 20 ray tracing cores. The 200 W TDP and dual-slot design confirm it is a discrete, high-power graphics card.

For the 680M, the data supports a clear position: it is an integrated GPU that matches entry-level discrete graphics cards from several generations. The percentile ranking of 57 and the tight clustering with the GTX 580, RTX 2060, RTX 3050 OEM, and RX 7600 indicate consistent performance across varied workloads.

For the Arc Pro B65, the data supports a hardware capability assessment only. The specification sheet indicates a professional-oriented discrete GPU with substantial compute resources, large dedicated memory, and modern display outputs. Without benchmark results, the database cannot rank it against other GPUs or confirm its real-world performance.

Where Each One Wins

The AMD Radeon 680M wins in scenarios where power efficiency and integration matter. Its 50 W TDP versus 200 W TDP means it suits systems without dedicated power connectors, as its IGP form factor and lack of power connectors confirm. The system shared memory approach eliminates the need for separate VRAM allocation. The PCIe 4.0 x8 interface is sufficient for an integrated part. The 680M also holds the only recorded benchmark advantage: its 57th percentile ranking versus the Arc Pro B65's default 50th percentile, though the Arc Pro B65 has no measured scores to substantiate that position.

The Intel Arc Pro B65 wins in raw compute capability based on specification data. It has more than three times the shading units (2,560 versus 768), more than three times the TMUs (160 versus 48), and two and a half times the ROPs (80 versus 32). Its FP32 performance of 12.29 TFLOPS is more than three and a half times the 680M's 3.379 TFLOPS. The 32 GB of GDDR6 memory with 608.0 GB/s bandwidth versus system shared memory gives it a decisive advantage in memory-bound workloads. The 20 ray tracing cores versus 12 also favor the Intel part for ray-traced content.

The Arc Pro B65 also wins on connectivity. Four DisplayPort 2.1 outputs provide professional display flexibility, whereas the 680M's display outputs are portable device dependent. The PCIe 5.0 x16 interface offers substantially more host bandwidth than the PCIe 4.0 x8 interface on the 680M. The dual-slot design with a single 8-pin power connector and 550 W suggested PSU indicates a card intended for desktop workstations, not mobile or compact systems.

The 680M's release date of January 2023 versus the Arc Pro B65's March 2026 release date means the AMD part has been available for a longer period, though both are listed as Active in production status. The 680M has a predecessor (Vega II IGP) and successor (Navi III IGP) in the database, while the Arc Pro B65 has neither, indicating it is the first entry in its product line.
