AMD Radeon 680M vs NVIDIA RTX PRO 6000 Blackwell Comparison

Head-to-Head Benchmarks

The data set contains one shared benchmark between these two GPUs, and the result is a decisive victory for the NVIDIA RTX PRO 6000 Blackwell. In the 3DMark Steel Nomad DX12 test, the NVIDIA card scores 16,408 points against the AMD Radeon 680M's 378 points. That translates to a delta of 4,240.7% in favor of the NVIDIA part. This is not a close contest; the NVIDIA GPU outperforms the integrated AMD solution by a factor of roughly 43x in this synthetic DirectX 12 workload.

Context from the nearest-rival data reinforces how different these products are in the benchmark hierarchy. The RTX PRO 6000 Blackwell's average benchmark score of 16,408 places it within 0.6% of the NVIDIA GeForce RTX 5090 D V2 (16,504), and essentially tied with the AMD Radeon PRO W7500 (16,415, 0% delta) and the AMD Radeon RX 5700 XT (16,361, 0.3% delta). It sits at the 59th percentile among all GPUs tracked. The Radeon 680M, by contrast, averages 15,270 across its three submitted benchmarks, a figure dragged down heavily by its 378-point Steel Nomad result. Its other scores — 23,468 in Geekbench OpenCL and 21,965 in Geekbench Vulkan — are more competitive with older discrete cards, but they are not part of the head-to-head comparison. In the 680M's nearest-rival group, it trades blows with the NVIDIA GeForce GTX 580 (15,283, -0.1% delta), the NVIDIA GeForce RTX 2060 (15,290, -0.1% delta), and the AMD Radeon RX 7600 (15,171, 0.7% delta), while sitting at the 57th percentile overall.

The conclusion from the benchmark data is unambiguous: on the single metric where both have results, the NVIDIA RTX PRO 6000 Blackwell is in a different performance class entirely. The 680M's wins column is zero; the RTX PRO 6000's is one. No amount of averaging across other tests changes the fundamental gap in this shared workload.

Architecture Differences

These two GPUs come from opposite ends of the hardware spectrum, and the architectural data confirms it. The NVIDIA RTX PRO 6000 Blackwell uses the GB202 chip built on TSMC's 5 nm process, with a die size of 750 mm² and 92,200 million transistors. That yields a transistor density of 122.9 million per square millimeter. The AMD Radeon 680M is a Ryzen-integrated graphics processor (IGP) based on the Rembrandt+ chip, fabricated on TSMC's 6 nm node. Its die is 208 mm² with 13,100 million transistors, for a density of 63.0 million per square millimeter. The NVIDIA part is over five times larger in die area and holds roughly seven times more transistors.

The compute configurations are wildly different in scale. The RTX PRO 6000 Blackwell packs 24,064 shading units, 752 texture mapping units (TMUs), and 192 raster output units (ROPs). It also includes 188 ray tracing cores and 752 tensor cores. The Radeon 680M, by comparison, has 768 shading units, 48 TMUs, and 32 ROPs, with just 12 ray tracing cores and no tensor cores at all. Clock speeds tell a partial story: the AMD IGP runs at a 2,000 MHz base and 2,200 MHz boost, while the NVIDIA card runs at 1,590 MHz base and 2,617 MHz boost. The higher boost clock on the NVIDIA part, combined with its massive shader count, explains the enormous throughput difference.

Memory architecture is another fundamental split. The RTX PRO 6000 Blackwell has 96 GB of GDDR7 memory on a 512-bit bus, delivering 1.79 TB/s of bandwidth. The Radeon 680M uses system-shared memory, with its bus width and bandwidth listed as "System Dependent." The NVIDIA card's memory clock is 1,750 MHz (28 Gbps effective), while the AMD part has no dedicated memory clock. In terms of raw output rates, the NVIDIA GPU achieves 502.5 GPixel/s pixel fill and 1,968.0 GTexel/s texture fill, versus the 680M's 70.40 GPixel/s and 105.6 GTexel/s. FP32 compute is 126.0 TFLOPS for the NVIDIA card versus 3.379 TFLOPS for the AMD IGP. FP16 on the NVIDIA part is identical at 126.0 TFLOPS (1:1 ratio), while the AMD chip offers 6.758 TFLOPS at a 2:1 ratio.

Power and physical design differ just as dramatically. The RTX PRO 6000 Blackwell has a 600 W TDP, requires a 1000 W suggested power supply, uses a dual-slot cooler with a 16-pin connector, and measures 304 mm by 137 mm by 40 mm. The Radeon 680M is an integrated part with a 50 W TDP, no power connectors, no slot width (listed as "IGP"), and no discrete dimensions. The NVIDIA card uses PCIe 5.0 x16, while the AMD IGP uses PCIe 4.0 x8. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, but the NVIDIA card offers 4x DisplayPort 2.1b outputs, whereas the AMD part's display outputs are "Portable Device Dependent."

Where Each One Wins

The benchmark data gives only one head-to-head result, so the use-case split must follow from the specifications. The NVIDIA RTX PRO 6000 Blackwell wins every category where the shared benchmark applies. In 3DMark Steel Nomad DX12, it is 4,240.7% faster. That single result, combined with its 96 GB of GDDR7 memory and 1.79 TB/s bandwidth, points to workloads like professional 3D rendering, large-scale simulation, and high-resolution texture streaming. The 188 ray tracing cores and 752 tensor cores further position it for ray-traced visualization and AI-accelerated tasks. Its 126.0 TFLOPS of FP32 and FP16 compute make it suitable for heavy compute workloads that the 680M cannot approach.

The AMD Radeon 680M is an integrated GPU designed for portability and low power. Its 50 W TDP and IGP form factor mean it fits into laptops and compact systems where a 600 W dual-slot card is physically impossible. Its benchmark results show it can handle lighter loads: the Geekbench OpenCL score of 23,468 and Vulkan score of 21,965 indicate reasonable performance for an integrated solution, though these tests are not shared with the RTX PRO 6000 Blackwell. The 680M's nearest rivals include the GeForce GTX 580 and RTX 2060, which suggests it competes with older or entry-level discrete GPUs in some scenarios. For users constrained by power and space, the 680M's 6 nm process and 13,100 million transistors in a 208 mm² die represent an efficient use of silicon — but efficiency does not translate to raw performance wins here.

In short, the RTX PRO 6000 Blackwell wins any task that demands throughput. The 680M wins scenarios where the alternative is no discrete GPU at all, or where the system must remain within a 50 W power envelope.

The Verdict

The data leads to one conclusion: these are not competing products. The NVIDIA RTX PRO 6000 Blackwell is a workstation-class discrete GPU with 24,064 shading units, 96 GB of GDDR7 memory, and 126.0 TFLOPS of FP32 compute. The AMD Radeon 680M is an integrated graphics processor with 768 shading units, shared memory, and 3.379 TFLOPS. In the only shared benchmark, the NVIDIA card is 4,240.7% faster. The 680M's wins column is empty, and its nearest rivals are older discrete cards like the GeForce GTX 580 and RTX 2060, not modern workstation parts.

Who should pick the RTX PRO 6000 Blackwell? Anyone whose workload requires the benchmark results shown here: professional rendering, compute-heavy tasks, or applications that can use 96 GB of VRAM and 1.79 TB/s of bandwidth. Its 600 W TDP and dual-slot form factor mean it belongs in a desktop workstation with a 1000 W power supply. The 59th percentile ranking among all GPUs, combined with a 0.6% delta to the GeForce RTX 5090 D V2, indicates it is a top-tier performer.

Who should pick the Radeon 680M? Users who need a GPU that fits within a 50 W power budget and an IGP form factor. It has no discrete dimensions, no power connectors, and its display outputs depend on the portable device. Its benchmark scores — 23,468 in Geekbench OpenCL and 21,965 in Geekbench Vulkan — show it can handle moderate graphics workloads, but its 378-point Steel Nomad result proves it is not built for high-end DX12 gaming or professional rendering. The 680M is the right choice for a thin laptop or compact system where the RTX PRO 6000 physically cannot exist.

The verdict is straightforward: if the task requires the performance level shown in the head-to-head benchmark, the RTX PRO 6000 Blackwell is the only option. If the task requires integrated graphics with minimal power draw, the 680M is the only option. There is no overlap.
