AMD Radeon RX 7900M vs NVIDIA Quadro P6000 Comparison

# AMD Radeon RX 7900M vs NVIDIA Quadro P6000

The database places these two GPUs in very different eras of graphics hardware. The AMD Radeon RX 7900M is a modern mobile part from the Radeon RX 7000 series, built for laptops, while the NVIDIA Quadro P6000 is a professional workstation card from the Quadro Pascal generation, now end-of-life. Their benchmark profiles are starkly separated: the RX 7900M holds a 95.1% lead in Geekbench OpenCL and a 115.7% lead in Geekbench Vulkan over the P6000. Yet the P6000 counters with 24 GB of memory versus 16 GB, and it carries a launch MSRP of 5,999 USD. The data suggests these cards serve entirely different workloads, and the comparison reveals how far mobile graphics have come since 2016.

Where Each One Wins

The AMD Radeon RX 7900M wins decisively in every recorded benchmark in the head-to-head comparison. In Geekbench OpenCL, the RX 7900M scores 129,499 against the P6000's 66,382, a 95.1% advantage. In Geekbench Vulkan, the gap widens further: 158,760 versus 73,590, a 115.7% lead for the AMD part. These are not marginal victories; they represent roughly double the compute performance in the same API tests.

The RX 7900M's overall average benchmark score of 97,487 places it in the 94th percentile of all GPUs in the database. Its nearest rivals include the NVIDIA Quadro RTX 6000 at 101,872 (4.3% faster), the AMD Radeon Pro VII at 97,131 (0.4% slower), and the AMD Radeon Instinct MI60 at 92,466 (5.4% slower). The RX 7900M sits comfortably above its closest competitors and is only meaningfully outperformed by the Quadro RTX 6000.

The Quadro P6000, by contrast, averages 69,986 across its benchmark results, placing it in the 90th percentile. Its nearest rivals are tightly clustered: the AMD Radeon Pro WX 8200 at 69,870 (0.2% slower), the NVIDIA RTX A3000 Mobile at 70,140 (0.2% faster), and the AMD Radeon RX 6600 LE at 70,829 (1.2% faster). The P6000 is competitive with these contemporaries, but it cannot approach the RX 7900M's absolute performance.

The use-case split is clear. The RX 7900M wins on raw compute throughput and modern API support, while the P6000 offers more memory capacity but significantly slower execution. For tasks that stress parallel compute, the AMD card is the dominant choice. For workloads that require large framebuffers or datasets exceeding 16 GB, the P6000's 24 GB allocation provides headroom the RX 7900M cannot match.

Architecture Differences

The two GPUs come from completely different architectural eras. The AMD Radeon RX 7900M uses the Navi 31 chip with RDNA 3.0 architecture, codenamed Plum Bonito, fabricated on TSMC's 5 nm process. It contains 57,700 million transistors on a 529 mm² die, yielding a transistor density of 109.1 million per square millimeter. The NVIDIA Quadro P6000 uses the GP102 chip with Pascal architecture, built on TSMC's 16 nm process. It packs 11,800 million transistors on a 471 mm² die, with a density of 25.1 million per square millimeter.

The process node difference is dramatic: 5 nm versus 16 nm. This explains the transistor density disparity, with the AMD chip packing over four times more transistors per square millimeter. The RX 7900M also has a larger die, 529 mm² versus 471 mm², despite having fewer physical resources in some categories.

Shading unit counts differ significantly. The RX 7900M has 4,608 shading units, 288 texture mapping units, and 192 raster output pipelines. The P6000 has 3,840 shading units, 240 TMUs, and 96 ROPs. The AMD card also includes 72 ray tracing cores, a feature entirely absent from the Pascal-based P6000, which has no RT cores and no tensor cores. Neither card has tensor cores listed in the database.

Memory architecture diverges substantially. The RX 7900M uses 16 GB of GDDR6 on a 256-bit bus, delivering 576.0 GB/s of bandwidth. The P6000 uses 24 GB of GDDR5X on a 384-bit bus, achieving 432.8 GB/s. Despite the P6000's wider bus and larger capacity, the RX 7900M's faster GDDR6 memory provides 33.1% more bandwidth. Clock speeds tell a similar story: the RX 7900M runs at 1825 MHz base and 2090 MHz boost, while the P6000 runs at 1506 MHz base and 1645 MHz boost. The memory clocks also favor AMD: 2250 MHz (18 Gbps effective) versus 1127 MHz (9 Gbps effective).

Compute throughput is where the RX 7900M dominates. It delivers 38.52 TFLOPS FP32 and 77.05 TFLOPS FP16 (2:1 ratio). The P6000 manages 12.63 TFLOPS FP32 and a mere 197.4 GFLOPS FP16 (1:64 ratio). The FP32 gap is 205% in favor of AMD. Pixel and texture rates follow suit: 401.3 GPixel/s and 601.9 GTexel/s for the RX 7900M, versus 157.9 GPixel/s and 394.8 GTexel/s for the P6000.

API support differs in DirectX version. The RX 7900M supports DirectX 12 Ultimate (12_2), while the P6000 is limited to DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4. The RX 7900M uses PCIe 4.0 x16, while the P6000 uses PCIe 3.0 x16. Power consumption also differs: the RX 7900M is rated at 180 W with no power connectors (an IGP form factor), while the P6000 is a dual-slot card at 250 W requiring one 8-pin connector and a suggested 600 W PSU.

The Verdict

The benchmark data is unambiguous about compute performance. The AMD Radeon RX 7900M outperforms the NVIDIA Quadro P6000 by 95.1% in OpenCL and 115.7% in Vulkan. Any workload that depends on raw shader throughput, FP32 compute, or modern API features will favor the AMD card overwhelmingly. The RX 7900M's ray tracing cores and DirectX 12 Ultimate support make it the only choice for those features, as the P6000 has neither.

However, the P6000's 24 GB memory capacity is its sole clear advantage. The database shows 24 GB versus 16 GB, a 50% capacity increase. For professionals working with large datasets, high-resolution textures, or multi-display configurations that exceed 16 GB, the P6000 provides necessary headroom. But that capacity comes with a bandwidth penalty: 432.8 GB/s versus 576.0 GB/s, making the RX 7900M faster at moving data despite its smaller pool.

The production status differentiates them further. The RX 7900M is listed as Active, released in 2023, while the P6000 is End-of-life, released in 2016. The P6000's successor is Quadro Volta, and its predecessor was Quadro Maxwell. The RX 7900M's predecessor is Polaris Mobile, and no successor is listed.

For modern workloads, the RX 7900M is the clear choice from the recorded data. Its performance is roughly double the P6000's, its feature set is more advanced, and it consumes less power (180 W versus 250 W). The P6000 only makes sense if the 24 GB memory capacity is an absolute requirement and the user can tolerate its slower compute and legacy architecture. The data does not support any other argument for the P6000.
