AMD Radeon RX 7900M vs NVIDIA RTX PRO 5000 Blackwell Comparison

The Verdict

The benchmark database positions the NVIDIA RTX PRO 5000 Blackwell as the clear performance leader between these two GPUs, winning all three recorded head-to-head tests. The NVIDIA card delivers a 128% higher score in 3DMark Steel Nomad DX12, a 96.2% advantage in Geekbench OpenCL, and a 78% lead in Geekbench Vulkan. The average benchmark score of 182,109 for the RTX PRO 5000 Blackwell versus 97,487 for the Radeon RX 7900M illustrates a substantial gap that spans both synthetic gaming workloads and general compute APIs.

The RTX PRO 5000 Blackwell is the choice for professionals who need maximum compute throughput, 48 GB of GDDR7 memory, and workstation-oriented features. Its 98th percentile ranking among all GPUs places it among the top tier of hardware currently tracked, while the Radeon RX 7900M sits at the 94th percentile. The NVIDIA card also carries the advantage of a PCIe 5.0 x16 interface, dual-slot cooling, and a 700 W suggested power supply, making it suitable for desktop workstation environments where space and power are not limiting factors.

The AMD Radeon RX 7900M serves a different purpose entirely. As an integrated graphics processor (IGP) with a 180 W TDP and no power connectors, it is designed for portable systems. Its 16 GB of GDDR6 memory and 256-bit bus deliver 576.0 GB/s of bandwidth, which is respectable for a mobile part but far below the desktop-class NVIDIA solution. Users who require a capable mobile GPU for creative work or light rendering should consider the RX 7900M, but those who need maximum performance and have no portability constraint should select the RTX PRO 5000 Blackwell.

The data does not support any scenario where the Radeon RX 7900M outperforms the NVIDIA card in the recorded benchmarks. The decision ultimately comes down to form factor and intended use: the RX 7900M fits into laptops and compact systems, while the RTX PRO 5000 Blackwell demands a full desktop slot but rewards the user with roughly double the performance in every measured test.

Architecture Differences

The NVIDIA RTX PRO 5000 Blackwell is built on the GB202 chip using the Blackwell 2.0 architecture, manufactured on TSMC's 5 nm process. The chip contains 92,200 million transistors on a 750 mm² die, yielding a transistor density of 122.9 million per square millimeter. This desktop workstation GPU belongs to the Blackwell PRO W (x000) generation and succeeds the Workstation Ada lineup.

The AMD Radeon RX 7900M uses the Navi 31 chip with the RDNA 3.0 architecture, codenamed Plum Bonito. It is also fabricated on TSMC's 5 nm process but packs 57,700 million transistors on a 529 mm² die, resulting in a lower transistor density of 109.1 million per square millimeter. This mobile GPU is part of the Radeon RX 7000 series and the Navi Mobile (RX 7000M) generation, succeeding Polaris Mobile.

The NVIDIA architecture incorporates 110 RT cores and 440 tensor cores, reflecting its workstation AI and ray tracing focus. The AMD architecture includes 72 RT cores and no tensor cores, meaning it lacks dedicated AI acceleration hardware. Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical.

The shading unit counts diverge significantly: the RTX PRO 5000 Blackwell has 14,080 shading units, while the Radeon RX 7900M has 4,608. This difference translates directly into compute throughput, with the NVIDIA card achieving 66.94 TFLOPS FP32 versus 38.52 TFLOPS for the AMD card. Interestingly, the AMD GPU reaches 77.05 TFLOPS FP16 with a 2:1 ratio, while the NVIDIA card delivers 66.94 TFLOPS FP16 at a 1:1 ratio.

The bus interface differs as well, with the NVIDIA card using PCIe 5.0 x16 and the AMD card using PCIe 4.0 x16. This gives the RTX PRO 5000 Blackwell twice the available bandwidth to the host system, which can matter for large data transfers in professional workloads.

Specification Differences

The process node is identical at 5 nm TSMC for both GPUs, but nearly every other specification diverges. The NVIDIA RTX PRO 5000 Blackwell operates with a base clock of 1740 MHz and a boost clock of 2377 MHz, while the AMD Radeon RX 7900M runs at 1825 MHz base and 2090 MHz boost. The AMD card has a higher base clock, but the NVIDIA card boosts significantly higher.

Memory configurations differ substantially. The RTX PRO 5000 Blackwell offers 48 GB of GDDR7 at 1750 MHz with 28 Gbps effective speed, a 384-bit bus, and 1.34 TB/s bandwidth. The Radeon RX 7900M provides 16 GB of GDDR6 at 2250 MHz with 18 Gbps effective speed, a 256-bit bus, and 576.0 GB/s bandwidth. The NVIDIA card has three times the memory capacity and more than double the bandwidth.

The compute resources favor NVIDIA across the board: 14,080 shading units versus 4,608, 440 TMUs versus 288, and 160 ROPs versus 192. The AMD card actually has more ROPs, which helps explain its higher pixel rate of 401.3 GPixel/s compared to 380.3 GPixel/s for the NVIDIA card. However, the NVIDIA card achieves a much higher texture rate of 1,045.9 GTexel/s versus 601.9 GTexel/s.

Power and physical specifications could not be more different. The NVIDIA card consumes 300 W with a 700 W suggested PSU, uses a dual-slot cooler, measures 267 mm by 111 mm by 40 mm, and requires a single 16-pin power connector. The AMD card draws only 180 W, is classified as an IGP, requires no power connectors, and has no listed dimensions since it is designed for portable devices.

Display outputs also reflect their intended environments. The RTX PRO 5000 Blackwell provides four DisplayPort 2.1b outputs, while the Radeon RX 7900M's outputs are portable device dependent. The NVIDIA card launched at 5,099 USD MSRP, while the AMD card has no recorded launch MSRP in the database.

Head-to-Head Benchmarks

The 3DMark Steel Nomad DX12 test shows the most dramatic gap between the two GPUs. The NVIDIA RTX PRO 5000 Blackwell scores 9,579.5, while the AMD Radeon RX 7900M manages 4,201. This 128% delta represents more than double the performance and suggests the NVIDIA card is vastly better suited for modern DX12 gaming and rendering workloads. The RTX 5000 Ada Generation, a close rival with only 1.4% higher average score than the RTX PRO 5000 Blackwell, provides context for how competitive this result is within NVIDIA's own lineup.

In Geekbench OpenCL, the NVIDIA card scores 254,116 versus 129,499 for the AMD card, a 96.2% advantage. This test measures general-purpose compute performance and reflects the raw FP32 throughput difference between the two cards. The NVIDIA A100 SXM4 80 GB, which sits just 0.9% below the RTX PRO 5000 Blackwell in average score, shows that the Blackwell GPU competes with data center accelerators in compute-oriented tasks.

Geekbench Vulkan shows the closest relative result, with the NVIDIA card scoring 282,631 against 158,760 for the AMD card, a 78% advantage. Vulkan performance benefits from the NVIDIA card's 110 RT cores and 440 tensor cores, which accelerate the kinds of workloads this API supports. The Radeon RX 7900M's 72 RT cores and lack of tensor cores place it at a structural disadvantage in this test.

Across all three benchmarks, the RTX PRO 5000 Blackwell wins decisively. The smallest delta is still 78%, and the largest reaches 128%. The Radeon RX 7900M records zero wins in the head-to-head comparison. For users evaluating these GPUs, the benchmark data consistently points to the NVIDIA card as the superior performer, with the AMD card's appeal resting entirely on its mobile form factor and lower power requirements.
